get some volks....u can get 17" volks that weigh the same as your stock 15's and a set of nitto neo gen tires will only run u about 420 bucks....just shop around...order tires online, if u go someplace like sears, they'll try to charge u 1300 just for 4 tires..i know, they tried that shit with me...i got my 17" Volk Racing SE37K's and 215/45ZR17 nitto Neo Gen tires for 2800 total...not bad considering the volks list for between 575-635 per wheel before tax and shipping....good luck wheel hunting
