I decided to put new 19” wheels and tires on my 2002 Boxster S, Michelin Pilot 4 S Fronts are 225/35 ZR 19 & backs are 265/30 ZR 19. I inflated to std front 29lbs and rear to 36, but was wondering, is this the right amount? Also, my previously correct speedo is now off 3 to 4 mph reading faster than GPS.

I know I’m not the only one with this wheel size and probably others have the same tire. What have you learned?
