So I just pulled a wheel (15x8 with a 4.5BS and a Mickey Thomson L60 I Tire) off my GTO to test it on the Malibu and it hit the frame. These tires measure 28" tall, 12.1" section & 10" tread. So I think I may be able to get away with the 275/50/15 which section is only 11.3" and a 10" tread. I believe it will be super close like you guys said 1/4". If I put a 1/4" spacer on with that I should be okay. Then again, The car sits about 3-4"s over the tires, so height is not a problem, I may just go with the 3.5BS. Anyone want to buy Prostars that are nearly new? Thanks again for all you input.
