147 1.6 TS, 3door. Nov 2003 18,890 miles in the UK

Tyres Dunlop Sport 2000E, 205/55R16 91V Front & Rear from new.

Front tyres approaching legal minimum and need replacing. Any advice
regarding other Brand/Type of replacement tyre. DO NOT intend replacing rear
tyres at present as they still have plenty of tread.

Any advice much appreciated.

Change the positon of the front and rear tyres in the manner that the frint
tyres put diagonal to the rear and vice versa.

NEVER diagonally change tyres; that's an old and old fashioned idea.
Keep them on the same side as most tyres are directionally bound nowadays.
If you put a tyre on the "wrong" side, it will be turning backwards when you
are driving ahead and i.e. the rain water will not be drained sufficiently.
And, although it sounds crazy for a front wheel drive car, on ANY car keep
the best tyres on the rear!!
So in your case, change the rear to front and put the new tyres on the rear.
Several threads in this NG have explained this in the pat, I won't repeat
that here.

For a 1.6 the tyres are not that important. Most brands/types will do.
If you're content with the present ones, I would suggest to buy 2 new onse;
at least you'll have the same tyres front and rear which is the best for
balance.

Nevertheless:
IMHO Alfa's perform best on Michelins. Although often the most expensive
(less cheap) tyre, the mileage is the highest, so per mile/km they often are
the cheapest in the end.

Don't forget to have the rear tyres balanced when you put them in frotn and
have the alignment checked. Mostly front tyres are unevenly worn due to
(slight) mis-alignment.

You dont change the tyre with the rim, only the tyre!!!!
Then you dont flip it!!!!!!!!!!!
It is not old fashioned, and it is stupid to have best tyres on the rear,
because you have to have better grip on front tyres!!

it's not stupid to have the best tires on the rear - even for front wheel
drive.
With best tires in front, in case of an emergency break, your car starts
spinning.
Always put the best tires in rear - they teach you that in advanced driver
classes (slip course etc)

cheers,

???? If you change a wheel diagonally (change car sides) you turn the
tyre and wheel around. Go and think about it! For a directional tyre,
it's illegal to have them on the wrong side of a car in the UK IIRC.
Usually they have 'outside' marked on one side.

>It is not old fashioned, and it is stupid to have best tyres on the rear,

Sorry..it IS old fashioned and you are wrong. Newer, more advanced
thought, considers it very bad to loose grip at the rear first. You
put your best tyres on the rear so the front looses grip first
(hopefully). This you can see and react to in a way you can't if the
rear goes first. The reasoning applies for all road vehicles. It's all
been explained here, and in other places, several times so, if you
need further clarification, do a google search.

I accept that losing the rear can be harder to control, however, the
majority of "offs" IMHO are through simply understeering off. Having said
all that there are many other factors such as weight distribution (having a
20 odd stone of people in the back, a boot full of compost etc.) that
probably have a greater influence. Add to that the nut behind the wheel
doing daft things like abruptly braking mid bend or failing to read road
conditions (the sign said 40mph therefore I must be able to go round this
bend in a monsoon at 40mph) and I am unconvinced a small difference between
front and back tyres really make the difference between spinning off and
staying in control.

However, a soft front and a hard rear maybe sufficient to change the
balance.

That's not the point though. If you're going so fast that the car will
understeer off the road, having the good tyres anywhere probably will
not help much.

Having the mother-in-law in the back seat should not affect where you
put your tyres - maybe their pressures though!

Having driven non-Alfas in the past, I can assure you that I've
experienced a huge difference. The 156 isn't too bothered, being
better balanced than some, but it's max cornering speed is also poor
compared to many cars these days.

I'd be surprised if the small hardness and softness difference of
modern road tyres had that much of an effect compared to wear
differences.

Considering the efforts manufacturers go to optimise weight distribution I
would suggest it does make a significant difference to the way a car
handles.

Unladen Transit vans can be quite tail happy!

I would say the reverse. The front end grip of my 156 with Bridgestones S03s
is incredibly different then the Contis it replaced (when new). Stick some
Dunlops on the front and it would understeer more. Stick some cheapo no name
tyres on the front and Goodyear F1s on the back and now check out the
balance...

Compared with worn tyres of the same type on one axle and new ones on the
other I believe the difference is less pronounced.

Well..it's fine by me if you want to swap your tyres round every time
you load or unload your Transit!

But you've now expanded the argument into comparing completely
different tyres from different manufacturers. I was talking about
softness vs hardness.

The point was the weight distribution makes more difference then the
relative tread levels front & rear

Well softer tyres = gripper tyres. Mixing new Pirelli P-Zeros and new p6000s
compared with new and worn P-Zeros would in my opinion have a greater
potential effect on balance.

Yes but do remember that the OP has a 147 and not a Transit and people
don't normally buy 147s if they're going to be loading them up
heavily!

Not always. Tread pattern, size and quality have an effect also.

We're just going round in opinionated circles now. I'm not convinced
by your arguments and you don't believe mine so..each to his own.

News,
Like I wrote, take some time reading earlier posts in this NG about where
the best tyres should be befor you start shouting about things you obviously
have no knowledge and experience on .......

I got Goodyear Eagle F1 GSD3s on my 156 and they have pretty good grip. Got
them off the internet from mytyres.co.uk and got them fitted at a local
wheel shop for £10 each. Ended up 40% cheaper then National or similar.

I'll second that. I've just had them fitted to the front for a second time.
Good grip in all conditions and they seem quieter than the factory fitted
Firestones and the Avons I've had in the past.

Having said all this, I have the 2.4jtd and do a good mix of all driving and
get about 10k miles from a set.

A few years ago, I studied some brands/types since my previous Michelin
tyres had no minimum tread after just 7.000 miles!
I decided to get me some new ones, Goodyear Eagle NCT5, and I still have
them, after 25.000 miles.

Don't try to let me believe that had anything to do with the tyres.
MUST have been a hughe out-of-line problem

No, seriously, no out-of-line problems.
But what was the case: only the side sections (inner en outer) were flat
(<2mm), the mid section had approx. 4mm. So my guess was that I drove to
hard through corners? The tyres weren't adjusted in-line afterwards, and the
next set of tyres didn't have these problems.

100% sure that that is a tyre pressure problem.
This indicates a much too low pressure!!!
Car should have been heavy steering as well.
Cornering too fast or out-of-line will show wear on the outside.

Bear in mind Dunlops are hard wearing tyres. Fitting softer, grippier tyres
to the front to replace hard worn ones may dramatically change the balance
of the car.

I would not agree that a 1.6 doesn't matter, you can corner just as hard as
a 3.2!

I was advised by one tyre fitter to fit Dunlops at the front and softer
tyres at the rear to prolong tyre life. As I was going in for 4 tyres I
preferred to get 4 Bridgestone Potenzas S03s all round and am really happy
with them. I will swap the fronts with the backs once the fronts are half
worn.

Tyre fitters are keen to promote grippier tyres at the rear to prevent
oversteer. Personally I think this is for the less clued up driver who lifts
off or brakes mid bend in the wet and blames the tyres for spinning off
backwards. However, if you are used to worn hard tyres at the front and
stick a set of Goodyear F1s or Bridgestone S03s on there you might find a
very different handling car underneath you.

Hope this helps
