UPDATED: w/Pictures 33's on Stock FORD rims (Bought some!)

I'm sure this has been asked before, but can 33x12.50x15's fit on Stock 15x7 Ford rims? A guy near me has some decent 33x12.50x15 BFG A/T's for $150 for all four of them.

There seems to be some debate on this... Some say it works, some say go with 15x8 or 15x10 rims.

When I had 31x10.5x15's on my stock Ford rims on my 2WD, they rubbed at full lock. I would imagine these 33's would be even worse, without some backspaced wheels.

I would consider getting some 15x10 rims if that would be the better route, I'd just need to know what backspacing I need to avoid extreme rubbing.

Thanks..

If I were you, I would get some 10 inch wide rims with 4 inch back spacing. Putting wide tires on narrow rims makes it "mushy" when you turn.

The stock rim size on your truck is most likely 7.5" or maybe even 8", those styled chrome rims never appeared in the 7" width as far as I know. But even with that a 12.5" tire is not recommended as it will very likely have problems keeping the bead set which could result in instant deflation at the worst possible time.. like when you're deep into a corner at speed. The better solution that will also look much better is a set of aftermarket 10" rims and to avoid excessive rubbing make sure they have no more than 4" backspacing and preferrably a little less.

YES. they will work. But the "recommended" width is 8-10"

Great, thanks for all the help guys. I don't want extreme rubbing on turns, so backspaced 10" wide rims will be more ideal for this.

mine seem to be what you are asking of (33 x 12.5 on stock Ford rims), and yes it does rub pretty bad because those huge lugs catch the radius arms at full lock, makes the whole truck shake. Get some nice 33's for that truck!!!

I have 33's on 10" wide with 4" backspacing and extended radius arms that have the clearance for bigger tires and they still rub at lock. Not nearly as bad as 8" wide wheels did though.

I've had 31x10.50's, 32x11.50's and 33x12.50's all on stock rims (8" wide wagon wheels) and they all rubbed the radius arms but only at full lock.

8" is the absolute minimum for a 12.50 tire IMO. I thought those wheels were 8" wide? Unless they're 4x2 rims?

My Bronco came with from the factory with 31x10.5R15 and it has never rubbed (AT or MT), but i can see any bigger/wider tires doing so.

I think they used a different rim. I used the stock wagon wheels on my 89 as well as on other trucks and they all rub at full lock. It just kisses with the 10.50's but it still rubs. 1/2" more offset and I bet they'd clear no problem.

Thanks Nick, I have always wondered what size tires you had on your awesome truck but never bothered to ask lol.

I would like to get some new rims for a summer set of tires while I'm at it but if $$$ is an issue then I'll just throw em on the stock Ford rims.

My truck is a 4x2, but the rims are off of a 4x4 truck. Not sure what the width is, I haven't measured them before. Maybe they are 8" wide, I'm not sure.

How about a 33x10.50x15 ?
Not a common size, but BFG makes 'em.

I like the look of a 33x10.5x15, but current funds won't allow for a brand new set. Used are fine as these will be my summer set of tires for the truck.

I would get some 33x10.5x15's if I found some for cheap around here, but the 12.50's seem to be more common on Craigslist.
