Question Question about tire size

Hey all,
It's been quite a while since I posted. Took me a long time to find the truck I really wanted. Now I'm back to the days of burning every dime on a truck

I ordered a set of Mickey Thompson Classic IIIs in 16x12 and I'm getting ready to order a 4" lift from rough country because the front springs are shot anyway. My question is, how tall of a tire can I run with that lift? Truck specifics are in my signature. Can I go an inch or two taller with bumper shims? And if the shims will help, how far should I shim it?

The kit recommends a 35x12.50 tire, but I know that I've seen people run those on an OBS F350 with just stock suspension, so I'm figuring I can go bigger.



97 F-350 ZF-5 CCLB 4x4 D60/10.25 3.55s. 216,000. 6637,FPR shim, 3" DP to 4" exhaust, leveled, ION Alloy 171's, 315/75/16 Kelly Safari TSR's, some cosmetic goodies.

NEEDS: Rosewood 160/30's, beans tunes, T500, Autometer gauges, lockers, some chassis parts, a few other things

Someday I'll do a full build on it.

Gone but never forgotten-1995 F-250 7.3 PSD 5 Speed 4x4 SC LB. Man-o-day did that truck get up and go.

A 35 is recommended I. The event of articulation where you will catch the bumper/fender/bed side

That being said I've seen 37's bumper shimmed maybe 1/2-1" but I would say go RSK over rough country

What all is needed for RSK? I've never actually seen a truck with that done. Be detailed if you can, I don't know much about it. And I'm assuming you run it with just blocks in the rear?

I'm more or less comparing the price of the kit with everything involved to do RSK, if that clarifies what I'm looking for.

Do a search on here. RSKs have been done a TON. they not only give you lift, but also give a much better ride. SuperDuty springs w the RSK give even a better ride

Looking for Blue 40-20-40 seats. PM me !!!!!!!

on a completely separate note, if i decide to hold off on the lift for a little while, what would need to be done to squeeze 315/75/16's under the truck?
