I have a 1996 F250 with a 4" lift. It currenlty still has the stock rims on it. However, now that I have the lift done I want to put after market rims and larger tires on it. I am not real good with sizes, etc of tires, but I would like to put larger tires and something with a little width to stick just outside the fender wells width wise. Any help on sizes that can work - tires and rims - would be appreciated.
I have a 96 F350 with a 4" lift too. I first had some 16x10 Weld Typhoons with 315/75-16 and they did stick out quite a bit. It was kind of annoying when it rained. The spray from the tires would reach all the way up to the windshield. I now have 16x8 MB rims and 285/75-16 tires. The front stick out maybe 1/2" to 1". The Typhoons are in the pic in my sig.
I have a '93 F-250 with aftermarket wheels/tires. It doesn't have a lift on it, but maybe it will give you a decent starting point.
Right now I'm running 33x12.50 BFG All-Terrains on 16.5x10.5 Pacer wheels. If I were you I would stay away from 16.5s. They are really hard to find tires for. If I had it to do over again I would have gotten a 16" wheel. The 10.5" width helps with fattening out the tires. My 33s measure about 31.5" tall on these wheels.
I've been looking at 4" lifts for awhile now and from what I've heard you can run a 36" tire without problems. A lot of places say you have to do some bumper trimming...but some people say you don't need to. If it were me and my driving habits I would probably get 35" BFGs or something equivalent. They are great tires that last a long time and handle really well on-road and in mild off-road.
You can go as high as what's available out there, 24", 26". They use the same bolt pattern as Dodges, and Chevys. I stuck with 16's because tires are cheaper. I'm over with 38's and 40's. It's a small fortune when you have to replace those. Besides they won't fit with a 4" lift. The most you can put are 35's, as recommended with the lift.
