hi, what do you guys run tyres pressures at when HOT for maximum grip. yoko 048r on 13's. MK indy 1800 Zetec, Alpha 2d, webers etc
regards, dom

At the end of the day the requirement for tyre pressures is going to depend on quite a few factors (tracking / suspension setup, ride height etc for one)....
20ish is IIRC what most people start at...

plenty of negative camber on front - slight tow out on front - spring rates and damping set to perfection - 4" off the deck

17psi, dont forget , its a very light car.

Agreed - I run 18psi all round - 16psi felt too sloppy.

16 PSI all round 18 felt to hard !!lol

(maybe that's because I'm bigger than you... )

Not only depends on the car, but the tyre too.

I've had a number of different makes of tyre on my car now, and they all respond best to differing tyre pressures.

The Goodyear Ventura's were happiest on 18psi
Changed to Hankook Ventus. Happiest at 20psi.
Changed to Toyo T1S's. Performed best at 16psi.
Currently on Bridgestone SO2's. Experimented as low as 11psi with these tyres! The only tyre so far that has performed best with different pressures front (16psi) and rear (18psi). Maybe because of the extra grip these superb (not sadly not made anymore) tyres give in the first place?
