I think somewhere i saw someone say with tires and air they weighed like 38 lbs or something like that. I wish I could remember where it was. He said he pulled the wheels off and weighed them and got that. I think he had the stock 16" tho, not totally sure tho
GabrielTRD: I would assume the 205/50/15 tires would be the grippiest tires you could get as they are the widest, and would have the largest contact patch for an agressive launch. But there are more people on this board with more knowledge about this than me. I should let them answer.
