Car Forum / Land Rover Cars / March 2008Tires, tires, tires
All, I'll have to change my tires one day or another and I feel a bit puzzled. At the moment I have BFG trac-edge 7.50R16 on 5.5in (?) steel wheels on my 110. I am very happy with this tire but it seem to be very difficult to come by. I read that the BFG Commercial A/T Traction is a very good replacement for it. Unfortunately, it doesn't exist in that size. I don't really want to loose ground clearance so I reckon that a size such as 235/85 is the closest I can get (in fact would give me a bit more ground clearance). However, the rim size recommended for that tire/size is min 6in. Is that a big problem? What do people do? Fred P.S. Sorry for the FAQ, but I couldn't find an answer to it anywhere. Fred Labrosse typed: > All, > [quoted text clipped - 16 lines] > > P.S. Sorry for the FAQ, but I couldn't find an answer to it anywhere. 235/85 is almost identical to 7.50 - within a couple of mm or so. BFG AT are a fantastic tyre - mine were doing around 30k miles on average. I'm pretty sure they will fit your rims.  SignatureRich B Take out the obvious to email me. A life?

Most of my customers get at least 40 and sometimes 60 out of their BFGs The commercial TA is not the same as the BFG AT is the replacement to the much loved Track Edge.

Perhaps driving style had something to do with it? :-) Ackshirley, I was going to write 50k, but it was a while ago and I though, ah, bollocks, no-one will believe that, I must have misremembered, and put 30k. > The commercial TA is not the same as the BFG AT is the replacement to > the much loved Track Edge.

I had to fit Wranglers on the RR4.6 and they seemed to be well on the way out by 10k. The TracEdges I had on the 90 had done 30k when I took them off, and they were about half-worn.

What do people do? Fit the 235/85 tyres to the 5.5" rims. I've never had any problems with 'em. The only LR rims I'd not really reckon to fit that tyre to are the old SWB rims. Old LWB are the same as the 110 ones (well, early ones anyway). If you're especially bothered, you could buy a set of "wolf" rims, which, IIRC, will allow you to fit tubeless tyres as well, which you can't do on the old type riveted rims. 7.50R16 is sadly a vanishing breed... and the trac edge is now defunct, which is a pity as it was a good tyre.

The 235/85 is so close to the 7.50 in diameter as to make no difference, especially for emergency use. I've had 235/85 on the wheels and a 7.50 spare, and no MoT ester has ever mentioned it.

A fitted tyre of a different profile to the other three is an MOT failure, but is not a failure if in the spare position.

Every tester I've known checks the condition of the spare (if not the size) because the intention is to fit it if needed which would then be illegal if there was anything wrong with it (including the size).

Bollocks! The populist folklore in this part of the real world says "Don't be so bloody tight and spend another £100 on a matching tyre. :-) Martin >>>>>> AIUI spare is not part of MOT >>>>> [quoted text clipped - 18 lines] > > Martin Heh - I only became aware of the significance of the "they don't check the spare" rule when a popular and well known chain of tyre, exhaust & other consumable item fitters stuck 4 new tyres on my car pre-mot. 1 of the tyres was a different size to the 3 others (a fail), but the old good spare was the same size as the three, so the MOT tester (my brother in law) swapped the wrong for the spare, passed and filled me in on the legal requirement. However, if one had a very shagged spare in plain view on a carrier the station may recommend a fresh one. :) >> >>>> AIUI spare is not part of MOT >> >>> [quoted text clipped - 18 lines] > "Don't > be so bloody tight and spend another £100 on a matching tyre. :-) Sounds good to me. ;-) And anyway, many new cars are now fitted with tiny spares so indeed, this can't be illegal.

The vehicle presenter should be informed when it is noticed that there is a defective tyre on a spare wheel. So you'll get an advisory for a duff spare but shouldn't fail. My new thing for today "spare tyres don't have to be legal for the MOT". Of course it is probably very advisable for it to be legal 'cause if you have to use a non-legal spare you'll be commiting an offence.

Heh, that would be hilarious. Maybe then designers or stylists will work round fitting a proper spare wheel in the first place. I hadn't thought about changing the wheel twice though, that can be a PITA. Martin > Maybe then designers or stylists will work round fitting a proper spare > wheel in the first place.

That's what the AA/RAC/Green Flag etc are for... they do the roadside bit, then Qwikfit or Tyres R Us bloke puts the real road wheel back on for you. I expect the vast majority of drivers out there don't do anything to their vehicle(s) other than put fuel in and take it to be serviced, some people I know don't do the service bit at all. It's only us silly sods who get dirty doing it ourselves, cause it's quicker than waiting and hour for the RAC etc to turn up. Having said that I'll be calling the AA should I get a flat on the DII unless it's dry, warm, stopped in a safe place and I don't need to be somewhere. I've moved the wheels in the past and they are right heavy, awkward, bar stewards to get back on the studs. SignatureCheers Dave. >Heh, that would be hilarious.

The VW Toureg is a huge car , but has a space saver spare.......That you have to inflate before you can fit it !!!! How f'ing useless is that on a 4X4. (They do provide a compressor for the job, how many of them will be robbed by previous owners?) Once it is inflated it has about as much tread as a bald wheel barrow tyre. Then you have to deflate it to fit back in the boot. SignatureMarc Draper >> Heh, that would be hilarious.

Honda Civic, you only get a can of goo that is supposed to inflate and patch your puncture. The spare wheel well in the boot (under a flap) is carpeted so they can claim the boot is bigger then the Focus. A triumph of marketing over intelligence.

I agree, space saver spares are silly, especially on a motor which has enough room to carry a full-size one. However, the same rules mean that you can use a 7.50 (radial, mind) as a temporary-use spare for a LR fitted with 235/85s, or even with something like 31x10.5R15. Provided you accept that there may be handling compromises and modify your driving accordingly, of course. SignatureAustin Shackles. www.ddol-las.net my opinions are just that Travel The Galaxy!

SignatureRich B Take out the obvious to email me. A life? Cool - where can I download one of those? I have been specialising in 4x4 tyres for over 20 years and by far the most popular over the years with the L/Rover tribe has been the BFG Trac Edge, it's a shame that when you find a tyre that suits almost every condition they stop producing it. It is fact that you should only fit the 235 section tyre on a 6J wheel rim, what about "Wolf" rims ?, I think we have a set of new tubeless rims in stock. The 750x16 size is getting hard to find but we have got Michelin XZL and XPC's in at the moment. MOT testers don't seem to look at tyre enough in my opinion, judging by the state of some of the tyres we change, we get the comments like "it only passed the MOT last week, think there is some blindness when it comes to tyres, mind you I would say that seeing as that's how I make my living.

Says who? I'm not being rude or facetious, by the way, I genuinely want to know. I've had that size tyre fitted to standard 110/LWB wheels with zero comment and zero problems. I've known many others who've done the same and I've even seen them fitted to SWB rims, although they do look a bit narrow and I wouldn't recommend it. LR themselves OK'ed fitting 205R16 on the standard SWB rims as far back as the end of SIII production, and a 205 on a SWB rim is about the same in terms of tyre width/rim width ratio as a 235 on a LWB rim - it's nominally 2" wider than the 6.00x16 which was the standard fitment. I've not checked on this exhaustively, but I wouldn't mind betting that LR fit them to the standard rims as well. Not all the new 110s are on alloys, and 235/85 has been the standard tyre for some time. I've also seen 205R16 on 7" disco rims, and frankly, the tyre looks way too narrow for the rim. 235/70 look good on disco rims, and 255 will fit an not look silly.

I've just browsed 3 or 4 tyre catalogs on the shelf here - they all recommend a 6.0 - 8.0" rim for 235 section 4x4 tyres, whether they be 235/75R16 or 235/85R16.

Austin, There is no technical book that will say any different, 235 section tyres are recomended to be fitted to 6-8J wheel rims, yes i know there are lots of vehicles using 235/85x16 tyres on 5.5J wheel rims but almost certain they will be tube type rims and as yet I have not come across any tube type 235/85x16 tyres, so you will be or SHOULD be using tubes which are not ideal as the inside of the tyre is not designed to take a tube. We see from time to time tubeless tyres fitted to the standard 5.5J tube type wheel rim WITHOUT A TUBE, which is not safe as there is no safety ridge to help hold the tyre on, the risk of "de-beading" (instant deflation) is great, the latest standard 5.5J wheel rim supplied by L/Rover are now TUBELESS but the largest tyres fitted are 750R16. I am not trying to sell loads of wheel rims, just trying to point out the facts. If you had an accident and a nosy insurance accesor found the wrong width tyre fitted to the standard rim and the accident was caused by a tyre deflation who knows what might happen with the claim.

My understanding (after some years in a similar business to yours) is that the stories about not running a tube in a tyre marked as tubeless are just that - stories. I have never seen a tyre company recommendation about not doing so, and have on occasion seen advice to use a tube after any sort of puncture repair. >> There is no technical book that will say any different, 235 section tyres >> are recomended to be fitted to 6-8J wheel rims, yes i know there are lots [quoted text clipped - 8 lines] > doing so, and have on occasion seen advice to use a tube after any sort of > puncture repair. Yes I agree, the main problem is chaffing of the tube on the ribbing or on those blasted build tags which Trac Edge were famous for. You must also accept the problem with heat build up when fitting tubes in most tubeless tyres. I am sure that over the years you like I have seen some most spectacular tyre and wheel combo's >>>There is no technical book that will say any different, 235 section tyres >>>are recomended to be fitted to 6-8J wheel rims, yes i know there are lots [quoted text clipped - 11 lines] > Yes I agree, the main problem is chaffing of the tube on the ribbing or on > those blasted build tags which Trac Edge were famous for.

How fast do you have to go for this to be an issue? I don't hang arouind and have been using tubes in tubeless for years without even the slightest hint of a problem. I do run the pressures on the high side though which probably helps. > I am sure that over the years you like I have seen some most spectacular > tyre and wheel combo's > How fast do you have to go for this to be an issue?

I had tubes in tubeless tyres and had 5 tyre deflations in the first month, so I kept my speed down to a max of 60MPH and pumped them up harder and it was fine after that. One day I did an extended motorway drive, much of which was at 70MPH+ and one of the tyres blew out. In all the cases, the tyres didn't seem to have any marks or knicks on the inside, but apparently despite lots of chalk being applied, it can get hot and the tyre sticks to the tube. Then, once the car is parked and the tyres cool down, the tube gets torn. All my tyre deflations happened after a journey of half an hour or so, I'd park up and it'd be fine, but when I'd come back, I'd have a flat tyre. The blow-out was odd, first the truck started bumping up and down like mad then the tyre popped, I think the tube started bulging out through the tyre on that one, neither survived so I couldn't really check them.

That sounds like the tube deflated and broke up inside the tyre which retained pressure for a while, hence huge vibration until the tyre finally failed. >> There is no technical book that will say any different, 235 section tyres >> are recomended to be fitted to 6-8J wheel rims, yes i know there are lots of [quoted text clipped - 8 lines] >recommendation about not doing so, and have on occasion seen advice to >use a tube after any sort of puncture repair. I've also seen tyres marked "Tubeless" and "on tube type rim, use inner tube". I think the problems come really from cheap crappy inner tubes, more than the tyres themselves. I grant you that you shouldn't fit tubeless on LR rims, but then I'd never consider doing so, in any case. But the size, per se, is another matter, and as I also said, 205R16 on 7" rims looks undersized, to me. There's also the point that 205R16 have been recommended on (IIRC) 5" rims (standard SWB) in the past, and if 235 is a problem on 5.5" then 205 is equally bad on 5".

A 235 is nominally 30mm wider than a 205 so should really go on a rim at least an inch wider, but as I said my 235's are happy on 110 rims. >> I grant you that you shouldn't fit tubeless on LR rims, but then I'd never >> consider doing so, in any case.

This was published by LR and repeated in the Haynes BoL for the late series IIIs. The 235 is nominally (slightly) less wider than 7.50, IYSWIM.

But a 235 is, (nominally), 235mm or 9.25 inches, how can that be less than a 7.50 inch tyre, whereas a 205 (205mm) is approximately 8.1inches. Well, according to my tape measure, but it is a cheap one from Asda's. :-) Martin >>>> I grant you that you shouldn't fit tubeless on LR rims, but then >>>> I'd never consider doing so, in any case.

I forget the actual rim sizes, anyone what the SWB ones were/are? But that's my point, if 205s are OK instead of 6", then 235s should be OK instead of 7.50s.

I think another part of the equation that we haven't mentioned yet is sidewall stiffness. A radial tyre with a soft sidewall handles significantly less well on a narrow rim than a cross-ply tyre of inherently stiffer construction. >>>> I grant you that you shouldn't fit tubeless on LR rims, but then I'd >>>> never [quoted text clipped - 20 lines] > handles significantly less well on a narrow rim than a cross-ply tyre of > inherently stiffer construction. And a 205 on a 4.5" rim is pretty horrible! >>>> I grant you that you shouldn't fit tubeless on LR rims, but then I'd >>>> never [quoted text clipped - 17 lines] > handles significantly less well on a narrow rim than a cross-ply tyre of > inherently stiffer construction. And I wonder whether the BFG Commercial A/T Traction is not stiffer than the BFG All-Terrain A/T KO, which would help in that case. >I will be only too happy to help with tyre problems if needed. > >www.ajstyres.co.uk J8 M25 Surrey.

But I too am a BFG agent of some 10 years standing, an independent Landrover specialist for the past 15 years. I have shelves full of new and used parts. Racks full of tyres. And a field full of sales vehicles ranging from the scrap to very almost new. But on this forum I will hardly ever mention it as it is not set up with the idea of commercial gain.
