I want to get some new rims for my sc430, cause the factory wheels look like crap. Does anyone know the offset for the lexus sc430? I heard that getting the new wheels will disable the tire pressure gauge. Is there anyway around it? I read the posting here and a lot of people are complaining about the run flat tire. i havent experience any problem with mine, no noise or anything, maybe i havent tried the other tires. anyways i was wonder if anyone knows if they come in the 19". Thanks.
