I would like to go with a 10 inch rear wheel and 8 inch up front in my shorty stepper, is this possible without any mods to the bed?
Thanks

I have 9" on mine with offset (about 4") it is tight........size tire 275/70/17 so 15" might be ok.....depending on the tire size.

this is how tight it is on the rear of my truck:

bed wood tolerance on rear of truck:

Is the front is your truck stock or do you have a later model crossmember and drop spindles. If so you could go with 8" wide wheels but not any offset like my truck.

15x8 on front with a 91 crossmember and no drop spindles:

17x9 ; no offset, 91 front crossmember 2.5" drop spindles:

it is tight up front when turning lock to lock !!!!

Hope this helps Kieth

Truck is stock best I can tell, I think I will go with 15 inch, How can I tell if it has drop spindles? I bought the truck as you see it here.
Thanks

You can have the lip of the fender rolled to get about another inch or so of room. If you go that route make sure you find someone with a rolled made for it. The PO of my truck cut the lip off and now the bed is all screwed up and its going to take a lot of time to fix it.

It's not stock in height. crawl under and look and take pics if you don't know what you're looking for. Someone will tell you what's been done. By the way, nice truck.

The guy I got it from heated to coils to lower it, now it rides like its on rails, got a set coming 1 inch in front 3 in back, hope that helps the ride.
Thanks guys for all your help!

I went 4 in the back and will have 2 1/2 spindles in the front and 2 in springs. The PO cut the front and took too much out so it bottoms out. I really noticed how bad it was when I redid the rear suspension. Now it rides great in the back and the front is horrible. lol
