I've been experiencing ABS/PSM problems ever since replacing worn out rear tires and using a different wheels on my MY02 996 C4S manual. I replaced the rears with exactly the same OEM sized tires, but with different wheels. Prior to tire/wheel replacement I've never experienced any ABS/PSM issues. New Sumitomo HRZ-III 295/30-18 at the rear on original C4S solid spoke turbo twist wheels, 11x18. 60% worn Sumitomo HRZ-III 225/40-18 at the front on 996TT hollow spoke turbo twist wheels, 8x18. Under normal braking in left and right hand turns, ABS or PSM activates causing slight disruption in balance of car. Normally the warning light would just flash on for a second (or not at all). This is fairly repeatable in certain turns, but not others. No problems straight line braking. Today, after an ABS activation incident, I received an ABS failure and a PSM failure warnings that stayed on. Both warning lights on dash and computer on dash saying to drive to workshop. Drove to safe location, pulled off and parked, turned car off, waited a minute, turned car back on and no warnings. I know mixing tire brands/models are bad; mixing old and new tires left and right are bad; but is it ok to mix hollow and solid spoke wheels front and back?
