Tyre Pressure settings

  CTR EK9 turbo

Ive embarrasingly checked and noticed ive been driving around with really low pressures (around 1 bar lower than they should be!) and after pumping them up to 2.1 and 2.3 bar, rear and fronts respectively, the cars road holding and "adjustability" (if thats the right word) has been greatly improved! Its like driving a completely new car. Its slightly more twitchy but it grips better and the rear end is more "malluable" and can be "pointed". Basically the communication between driver and car is much better now ive done this.

Have any of you lot played around with your tyre pressures to achieve better lap times or quarter mile times etc?

thanks in advance, Si

The higher pressure you go the better steering response and qicker acceraltion from rolling starts however the grip will be reduced cause the tyre will have less downforce (i think thats the word) and will be more likely to slide under cornering.

and the higher the pressure, the less the tyre will flex under cornering and stay its intended shape, provided youve got enough grip on your tyres, should give better grip....? obviously dont go too high with pressure as itl slide like you say..
