Okay, I have an 09 Reg Cab 5-Lugger (15" wheels). Just ordered my 3" lift and am trying to figure out wheels and tires. I was going to go with new rims, but I'd like to save some money and maybe get them at a later point. So, what issues (if any) will I have putting 31x10.5x15 General Grabber AT2s on the stock rims? I've been looking for the width of the stock wheel, but havent' found much. Tirerack says you can use between a 7" to a 9" rim, and measured with an 8.5". I have a feeling the stock rim is closer to 6", but I'm not sure. If I can't fit this tire, what would be a close size that would work? Thanks.
PS Here's a pic of someone who's got stock rims with what looks like 31's (BFGs). I don't think it looks too bad.
