I just put the BFG AllTerrain T/A KO in LT315/70r/17 on my 2003 F250 Crew Cab 4x4 and am pretty surprised they fit with minimal rubbing. I put on 15mm spacers and still get some rubbing on the leaf springs about 1/2 turn before lock.

The rims are 2009 F250 17x7.5 like these .

People seem to report and say there would be clearance issues but I am fine in the fender wells, bumper, calipers etc... . just the slight rubbing against the leafs.

Anyone have a more specific size spacer and or brand? I used what was available which were similar to I would prefer to get perhaps a 2" spacer with 8x170 studs .

Overall diameter is about 1.5" taller.

 

These new BFG's got a test today in some of the worst kind of gross weather. It is about 20 Degrees F and has been for a few days then we had about an inch and a half of snow this morning. The roads were a mix of fluffy loose powder , slush , wet salty run off, plain old ice patches and all of the above on on-ramps and exit ramps. I drove everyy type of road from 20mph residential to 65mph highway and twist turny hilly roads. I left my hubs locked (manual) and only engaged 4WD to be safe going up a turn that was unsalted and compacted snow.

Overall I'm amazed with these tires bite into the road. I had no white knuckly moments, amazing predictable steerning and the only skid marks made were in my shorts when an SUV couldnt stop at an intersection I was in.

I know my Mickey Thompsons would not have gotten me out of my development.
