Will these wheels & tires fit my 13 Express?
 
Picked up a nice set of wheels/tires today for dirt cheap. They are 18x9 wheels and 35/12.5/18 Toyo MT's. I have to use some billet wheel adapters, which come between 1" and 1.5" thick. I haven't been able to remove a tire yet to measure the backspacing/offset, but they appear to have roughly a 3.5"-4.0" backspacing. I'm going to bring the truck up about 2.5" to clear the 35's, but wondering if I will have problems getting these wheels/tires to fit?

should be alright as long as have the right adapters, add that 2.5inch level, you should have very minimal to no rubbing, maybe some at full lock in reverse

I hope that's the case! My half-ass measurement for backspacing with the tire on was around 3.75"-4.00". Which would be like a -25mm to -32mm offset. I'm afraid they're gonna stick out too far with a 1.25" adapter & 12.5" tires on there.

You'll need to find out what the actual offset is of the wheels before I can give you some solid info. The wheel should list the offset on the back of one of the spokes....

If they are a -24 or larger you're going to rub, no question. Mine are -12 offset with 35x12.5 Toyo MT's and I rubbed when I had a 2.5" level. It was very minimal and I did get rid of most of it, but it was still there. With a -24 sticking out a half inch further you'll have even bigger problems. Then if you have to use the adapters to make them work you're screwed.... You'll be sticking out about 3.5-4 inches with that set up and you won't be able to turn very far before you either hit your fender or the bumper.

I appreciate your comment. What about going with less tall tire (33") be fine? Or maybe a more narrow tire, like a 265?

Going with a shorter tire would definitely be better for you. It's the height that will make you rub, not the width....

Honestly, your best bed would be to get a set of wheels with the proper bolt pattern so you don't have to use the adapters (I'm assuming that's why you're using them) and then run the 35x12.5's. That's what I would do at least....

hmmm lots to think about. Thanks again for the input. Just wish I were able to use these wheels since they're the type of wheel I originally wanted on the truck (Moto Metal 951 chrome), on the other hand I also want 35's. So you're probably right on the money with me selling the wheels (5x4.5) and keeping the tires.

Last question, since I've been thinking about doing a small body lift, like a 1.25" or 1.5", would that work with the level to not rub? I'm gonna run up to a tire shop in awhile & have them measure the wheel.


Edit: Got one of them measured. It is indeed 4.5" backspacing. And of course I noticed today a stamp on the spoke that says "ET -12". Didn't know what ET meant which is why I didn't mention it.

So the breakdown: 18x9 Moto Metal 951 on 5x4.5 Jeep bolt pattern, 4.5" backspacing (-12mm offset), 35x12.5 tire. Now I'm confused on what options I have if I were to use 1" or 1.25" wheel adapters. The size would be perfect for a 12.5" tire minus the wheel adapter width. Guy at Discount Tire urged me not to use a wheel adapter as he said he personally had a wheel come off one.

Last thoughts before they're sold?

Definitely not a fan of adapters... They just seem a little sketchy to me. And even with a 1" adapter you're going to run into rubbing issues. I'd be selling the rims and getting some with the proper bolt pattern.
