new wheels and tires on my 850 Spyder

[Dave Bassett]

I use 22 psi front, 25 psi rear cold.

Is that for track or street?

I can see that for a track tire. I used as low as 19 cold on my Nittos and Falkens. On street tires I run 32psi

They are Nankang ARI's which are R spec tyres and road legal. They are not that far off the handbook recommendations. The fronts are higher. The recommended pressure for the tyres from the tyre manufacturer is 27 psi hot. I think it's best to start with the tyre makers' recommendation and get the right ratio between the front and rear till you are happy. The Yokohamas I had previously were higher. The front of these cars are very light so the fronts don't really get warm enough. The fronts are up to 22 mainly to reduce the understeer!

It's for the track but would be fine on the road.

Mine are curently at 20/25 front/rear for leisurely around town street use.
