I have a 2006 F150 STX 4X4 with stock 17 X 7.5 rims on. At this time, I'm looking to just upgrade the tires for winter that will last me a while until I can do a real lift or a leveling kit and then throw on 33's or 35's on it. On that stock rim, how wide and tall can I go with out rubbing? The stock size is a : LT255/70R17. I know I can run a LT265, no problem, but can I run a
LT285/70R17 without rubbing issues? The LT285 does fit on a 7.5 wide rim but I don't know with the offset if it will rub the inside or outside to much? Has anyone done this and had no problems?

 

I've got 35's on my 17 stockers and I rub, but when I had 33's I had no problems!

 

The 285x70's should fit easily on a stock 4x4, leveled you can fit a 295x70 or 305x70. A 315x70 can be squeezed on but you may get some rubbing with the stock wheels.

 

I agree.

 

Thanks for the insight. I put my hands behind the top of the tire and felt around, it seemed like I might rub on a sway bar or upper arm but I think I'll probably run LT265/70R17 on the stockers for now and then upgrade with a leveling kit later on so I can run 33's, or add a body lift to run 35's. Thanks for the knowledge guys

 

You can run 35's on a leveled 4x4 on the stock wheels or aftermarket wheels with close to stock specs. You don't need a body lift. Don't forget about the 305x70x17 which is a 34" tire, probably a better fit on a leveled truck.
