u can probly run those on stock rims but the back spacing makes a tracer so much more stable in turns. if u r going to buy get an 8" wide rim with 3" back spacing u can run up to a 12.50" wide tire with no problem. i use to run 31x13.5 TSL on these rims. get some chep white wagon wheels and rino line them with Wal-Mart special bedliner.
