Hi,
A bit of background info - car is a 1.8SS with 15" CR500's. Only had the car since late last year and throughout winter on cold/damp roads treated the throttle with utmost respect to prevent any end swapping and have never had any issue. Until now....
Now that I have more confidence and have better weather I have been testing the boundaries somewhat, only to find they are nowhere near where I thought they'd be. Even with an open diff, on roundabouts at slow speed or even just pulling out of side roads the lightest use of throttle and the back end wants to get home before the front...
I noticed the rear tyres were looking a bit soft so checked the pressures all round - both fronts were 22psi (no issues with grip at the front at all, though that would seem a little high perhaps ?) and the rears were only 12psi, which I think is really rather soft.
I understand the rationale that more air = less grip, but is it possible the rears were so soft the sidewalls would deform under cornering forces and cause them to lose grip more easily ? I've put 18psi in them now but am wondering if they will be even more skittish when I'm next out or will they be better now ? Any thoughts ?
Cheers,
John
