Seems they sent me the wrong backspacing. I have Moto Metal 951's with +30mm backspacing. Will they fit on my truck with a 6" lift with 13.50 inch wide tires or will they rub? The lift is a Fabtech.

 

30mm+ isn't backspacing that's offset, but there are a lot of conversion charts that will tell you what that amount of offset will turn into for backspacing. I believe you said your new wheels are 18x9's and with 30mm+ offset that would give you 6.18" of backspacing. I don't know what fabtech recommends for wheel width and/or backspacing (should say in the instructions or you could give them a call) but you might or might not rub. Oh and in case you're wondering how much your new wheels will stick out compared to your stock wheels it's 0.82 of an inch further...AKA not much further

 

THanks yeah I knew the backspacing was 6.18 brain fart I am so pissed this is not what I ordered and everything is being installed tomorrow and I am in Iraq.

 

I'd personally would have them return the wheels and get same ones but with 5" or 4.5" of backspacing. I know how messed up orders can **** you off when over there...has happened to me a few times

 

I'm not sure, but I don't think you can use a wheel with 6 inches of bs with a Fabtech lift. I believe the oem wheels may fit using oem size tires.

 

yeah I am hoping the shop installing my lift can swap them out. He offered to put on some billet cast spacers but I don't want to go that route if I don't have too.
