What sort of tyre pressures do you lot run

for road and track if you know.

I just noticed I seem to be getting a far bit of tyre wall marking when cornering fast lol

I think last time I put something like 30/32 but cant remember to be sure :?

cheers

I usually prefer about 34f/30r when tyres are warmed up to operating temperatures. Get a good tyre gauge.

Don't forget to rotate the tyres too. The front tyres wear quite a bit more than rear tyres after 1k or 2k of driving. Rotating them will bring the grip back to the front.

But grip at the back is just as important :D if not more, just run the fronts down and get a new pair :D

32 all-round, but I'm going to try a little lower on road, cos the ride is rather harsher than it should be I reckon.

The front tyres do most of the work on these cars. The way I drive them, I like the rear to lose traction round tight corners with throttle-lift. And, with grippy fronts and a torquey engine, just power down again to straighten the car. They just don't make FWD cars like this anymore.

your best tread should always be at the back.......

IMO, Handling is too neutral on the Williams when there's too much rear grip. Just doesn't feel French to me when the rear is tamed. Plus with all that torque to pull the car out of trouble, I don't really have to worry much about what the back it doing.

Going to stop off at the garage on the way home and give 33/34 front and stick to 30 in the rears :)

cheers for all the info every one :D

yea but if you have it like that mate, you have to be very careful what your doing, its all very well having it so it slides out at the back, but what about when you have another car at the side of you

I doubt he's going to get himself into a situation where he's going sideways with another car in very close proximity. And as he's had the car for over 10 years, it proves he's had no problems with that setup so far!

I had this discussion with Stromba ages ago. He rightly said, and as tyre manufacturers recommend, the best tyres should go on the back. But personally I'd always go for the better on the front, because a FWD completely lives on front-end grip.

Of course, if you're driving around on tyres you'd be nervous about putting on the back, they shouldn't be on the car at all.

Well I put 33 in the front and 28 in the back (only because the rear is stripped out at the moment).

Will give the tyre shine time to wear off and then give it a hammering :D

No worries. Am mostly an 80% limit driver, plus not so much slipping these days anyway. But it's a handy option to be able to throttle steer tighter into a corner - if I need to. Frankly, the car does most of the work for me when it is set up properly.

But am curious, what's the reasoning on putting grippier tyres at the back? I would have thought it logical to put the grippier ones in front to tame the understeering tendencies of FWD cars. I thought grippier rear was more for RWD cars.

It's safer. Understeer, rather than oversteer, is easier for your average driver to handle. That's why tyre manufacturers recommend putting the best tyres on the back. And it's also why car manufacturers now setup cars with an understeering nature nowadays, and why they don't make FWD cars like they used to :wink:

^^^Its for gheys as well!

Garages always tell you to put new tyres on the rear, giving better rear grip (understeer) like zollo said, but imo fwd cars need to have better grip at the front as thats where the power is being put down, and all the weight is. Id rather a touch of oversteer than a bundle of understeer and end up in a hedge!!!

Imo the back only snaps on clios if your pelting round a corner far too fast and its slippy, or if you force it into a lift-off oversteer situation.

Heh, being the kind of guy that never listens to advise nor read the ****ing manual - oversteering in a FWD car has always been my cup of tea. And with most french FWD, their chassis are all so "talkative" at the limit - it's a piece of cake for an above-average driver to pick up throttle-steer. It's not so much about showboating (maybe sometimes :)) but having an extra dimension of control when cornering fast.

found a down side to running higher pressures in the front, great understeer in the wet this morning lol
