hi I am new to the forum. I have a 1992 f150 4.9 straight 6 4x4 I'm restoring and I have a few questions about tires. I want to know if I can get 33x12.50 tires to fit haven't decided if I'm gonna go aftermarket with rims or not if so what kind of offset will I need. I will first put a 2.5in leveling kit in the front Or what will I need to make this work? I like the look of a wider tires and a 33 just concerned with rubbing. Also I would like to stay away from lifting it don't want steering issues. Also will 33s be a bit much for the 4.9 to push?

What I've gathered from reading here is: 31" no problem, 32" maybe going to rub the radius arm a little, 33" better be lifted a bit, 35" lift it a lot.

What gear ratios do you have? I have 3.08 gears and that's the only reason I have the standard tire size on my truck

I have one with 3.08, and standard size 2.35 x 75, and I don't think I'd go much bigger, it isn't struggling now, and it seems geared properly. I have another one that the door post says 3.55, and if that can be believed, it is a bit too low even with 31" mudders on the stock Alcoa wheels. I need to put the 3.55 one on the lift and count rotations, I suspect it has it is lower than 3.55 .
