I have experimented throughout last season and I found my 185/14 (60
profile) tyres gave the best grip/handling at speed with 32psi fron and
34/35psi rear. Working on the +5psi rule for circuit work this would
mean, of course, 28psi front and 30 rear - but I normally don't worry
about front/rear differences when just driving normally and would stick
with 28/30psi all round.
You still haven't let on with your tyre sizes?
BTW I think my poor little car is going too fast for my 185s now - so I
am just about to put in my order for 205s (making up five and a half
inch wide rims on standard centres to try to keep within trak). You
reckon *you* have heavy steering!
Oh yeah, I had better acknowledge Barney's tyre advice before he tells
me off!
