what pressure to run Yokohama Advan A032R? ? ?

[Larry C Leung]

I'm guessing, since it's carcass is still that of a street tire (as are
all DOT tires, by law) you start at 43 psi. The only tire to run
significantly lower pressures is the now discontinued final generation
BFG Compt T/A R1 which had differentiated sidewall stiffnesses. The new
G-Force series has standard carcasses. Personally, start high, check
tread temps (ideally even across the tread, but on roll prone, strut
suspension cars (uh, Audis) I'd expect the outer third to be warmer. Go
as low as you can while keeping temps within say 4 degrees F across the
tread, if possible. (I'd be the first to say my stock class GTi on
regular carcass tires has about a 12 degree spread, until I took the
camber WAY negative (1.6 degrees). If you need to lower, do in about 2
psig increments.
