How big can I go on my rear tires without causing traction problems on the front. Today I have 275 / 35 / ZR18 on back Michelin Pilot Super Sports and 225/40/ZR18 Falken on front. Bummed the new rear tires wore out fast 18 months compared to front used over 3 years. I'm told that big on back can create front oversteer. So what should I do to optimize balance, treadwear and traction yet still have fun taking fast hard turns freeway or racetrack?
