Ok, I'm sorry if this is dumb to ask but here it goes. I was given some 28"x10.5 x 15 slicks. I want to find some el cheapo rims to play at the track. What do I need for a 15" rim on an 04 cobra? 15x10? 5 x ? lug. Also, I hope I dont need bead lockers. Sorry for being such a greenhorn. Thanks for any info/help!!:rolling:
