I'm running 33X12.5's on my truck with about 1" of lift. I have spacers front and rear. I did a little trimming an pounding of the front wheel well. It was free, took about 45 minutes, and they clear fine. They are on stock wheels.

You can fit tires up to 33/10.50/15's on the truck with no lift at all. You may have to flatten the pinch weld in the front end so the tires don't rub when you're wheeling it though. Then you can lift it a little later on if you want to.

As far as gears go you will want 4.56's with 31 inch tuires, 4.88's with 33 inch tires and 5.29's for 35 inch tires. The gears are really easy to install if you can find a set of Toyota third members that have the gears already in them, then just swap in the thirds. This can be done in the driveway in a couple of hours with hand tools.

Decide what you want the final product to be and work towards that goal so you don't end up doing things twice.

 

One thing that is helpful on these forums is to fill out your signature with things like engine, lift, etc... Sometimes that can change what advice one gives.

TONS of pictures at the link in my signature showing 33x10.50 being wheeled hard with no front lift (I fixed the saggy butt that all 2nd gens seem to have)

But, yeah, if it's a 2WD, 31's is pushing it. My '89 rubbed BAD with 31's.

 

True, but I'm assuming you're lifting to fit bigger tires anyways, so you're gonna have that amount of COG increase anyways. The suspension or body lift increases the COG on top of the tire height.

 

axles going up is a good thing!!!!! keeping the body as low as possible while having the axles up higher, is good. Ground clearance is a good thing, no?

 

I was referring to raising the centre of gravity. No one will argue that more clearance under the axles is a bad thing.

 

sorry, your last sentence sums up the fact that it is the best for performance gains.
