Car Forum / Land Rover Cars / October 2004Tyer pressures for a 110CSW
Please , anybody. -- Your help is, as always, greatfully receved. Rory Manton 1957 109 Series One, Daisy 1965 Series 11 SWB GS , Rose. >Please , anybody. what size tyres? when I had mine, with 31x10.5R15 on it, I used to run about 34 all round, and up the rears for heavy loads. ISTR 36 all round for 235/85R16 which were on it before, and similar for load. The heavy loads mine got were transferred from a big trailer. Later found that I was loading it nose-heavy; in the unlikely event that I haul hay on it again, I'll pay more attention to the load distribution. 36psi all round > 36psi all round This is about what I use. I've messed about with various diferent pressures and have settled on this which seems fine for everything I do and the tyres look to be wearing OK. The 28 that others have mentioned for the front seemed a bit too soft, but that may be because I've got the weight of an 8274 + bumper, whatever that weighs. On a normal 110 it may be fine.

On a normal 110 it may be fine. Remember too that when manufacturers set tyre pressures they err on the low side to keep road noise down and ride quality up. Much of the Ford Explorer/Firestone tyre fiasco in the US is being pinned on the recommended tyre pressures being significantly too low for extended road use at speed. Radial tyres do not suffer from the problems of uneven wear from incorrect inflation anywhere near as much as cross plies - and with their softer sidewalls do need significantly more pressure to stop them deforming whilst cornering.

It is true that running 36 in the front of the disco makes it a bit harsher. however, it also makes a big improvement to the handling. Difficult to get a definitive answer as no one seems to give official figures. Even Lode Lane have'nt got a clue nor most dealers. I found somewhere a set of figures at 28/35 but uprate on a load with 235 tyres, this seems to have given me about 50k miles on BFG AT's, but I have no idea whether this is good or not. Main thing is the tyre temp does'nt seem too bad at "high" speed so it must be near correct. > Please , anybody. > -- [quoted text clipped - 4 lines] > 1957 109 Series One, Daisy > 1965 Series 11 SWB GS , Rose. > Difficult to get a definitive answer as no one seems to give official > figures.

Official tyre pressures in my Australian owner's manual and vehicle placard vary from 35/35 unloaded and speeds below 120kph to 45/65 for full load and speeds above 140kph. I use 35/35 light loads, 35/45 moderate loads, 45/55 full load, as there are no speed limits above 110kph round here. JD Twas Wed, 29 Sep 2004 18:58:55 +0100 when Rory Manton <rory@griffon65.freeserve.co.uk> put finger to keyboard producing: >Please , anybody. I have the original handbook for my 1984 110 here. on the back it says..... 7.50 R16...... 25/25 - 30/42 7.50 x 16...... 25/30 - 30/48 now why the hell would crossplies need higher pressure at the back compared to the front when unladen and radials do not? odd that I have 7.50x16 cross plies and I run at 30 all round (rarely carry much weight).
