What is the max tire size i can run on my 97 f-250 with no lift and twin I beam with out rubbing the front bumper and still be able to run chains?

I don't know about the TTB front end but with my d60 and a trimmed bumper I'm running 315/75-16s and they only rub on the leafs when fully turned

It was on my gasser, but I had a pretty worn out set of 285/75-16 on it and they didn't rub. On my 97 with an add a leaf(I think, has three leafs) with 285s they only rub on something(don't know what) when I crank the wheels all the way, thats without trimming or shimming the bumper or anything.

you may want to figure out what they're rubbing because if its the leafs thats not gonna hurt anything as long as you dont keep rubbing them but if its the bumper it could easily slice your tires

Ya I know I should find out, but it will have to wait til spring, I don't drive the truck in the winter. Only have put about 5 miles on the new tires and I only did it once.

Well does anyone have any tips about trimming the bumper and make it look stock?

I don't have any tips about trimming the bumper, but my dad bought a 95 F350 with 305s I think and the bumper was trimmed, but also shimmed forward, didn't look too bad, it was like 3/4" or so. It may be an alternative to trimming it, just a thought.

I run 285/75 16's and it rubs on the leafs. Ive also got a set of 305/55 20's and i had to shim the bumper and trim it. Ill get pics in a bit of how i trimmed it and it doesnt look too bad you cant even notice from 10 ft away

i had 285x55x16 on my 250 (basically 33x10.5x16's)and the only time it may have rubbed would have been going over a big bump or ravine head on without turning the wheels. shimming the bumper would have helped but i put a bumper replacement on and never had a single problem with rubbing. it looked like this

i run 33x12.50r16.5 no issues, but i have a full replacement bumper on mine so no big deal on the bumper, but i dont rub anything either
