Rim backspacing question

Hello, I have a 99 f250 which i have the kit to level the front 2.7 inches. I am looking into putting 12.5 wide by 35 inch tires on the truck. I know of a set of 16.5 eagle alloy rims which are 9.8 wide with 4.81 backspacing. Will i have any major problems with that size tire on that rim with that backspacing? the ad im looking at, the guy says the rims are off a 2004 f350. I know the backspacing might be different on those trucks. But i looked up the rim and it is 4.81 backspacing. Please help me out

Might rub on a tight turn, or off-road turning.

Re: Rim backspacing question

Never heard of a wheel with those specs. Are they a 10" rim, or did the guy measure 9.8" which would indicate a 9" wide wheel (measured in the bead area). If they are 9" rims with 4.81" backspace then the offset is around 0 to +6mm which should fit like a stock wheel. Depending on how aggressive the tread is, you may have slight rubbing on the springs at full lock.
