195/50/15 Toyo T1-S and Toyo 888. Toyo recommend 17-20psi for a sub 800kg car. My 1500kg daily driver runs 35psi in the fronts, with a (for arguments sake) 60/40 weight split (so 450 kg per front tyre), thus 36 in a relatively light car seems seriously high. If it works, fair enough, but it seems theoretically quite some way from optimal.
I don't have any problem with excessive sidewall deflection with 17psi - it was one of the first things I checked when reviewing cornering shots.
