Default Tire Question

Would a 33 inch 12.50 tire fit my stock 20s on my 09? And yes the tires are for 20s. Thanks for any advice

They will not fit with the factory wheel setup.
The tires will make contact with the upper control arm.
You can do this setup with wheel spacers if you choose to keep the factory 20's.
You need another .75" roughly to clear those arms.
And then, you may run into rubbing on the rear of the fender liner.. mudflaps depending on how thick they are can be an issue as well.

I'm sure someone here can verify this, but i do know for a fact that anything wider than 11.25 - 11.5" or so.. depending on the side lug of the tire, will rub that control arm on the factory 20's. Go ahead and take your hand and run it along the inside of the tire, at the top.. and that will tell you how much room you have... or don't have in this case. Your Factory tires on the 20's are 11" wide just so you know.

Easy solution.. alot of guys are running a 285 width in a mud tire and clearing with ease.

Hope that helps. Anyone can correct me if I'm wrong.

Not completley true. I am running 33/12.50R20 Toyo M/T on my factory 20's with no spacers. Admittedly they are close, but after carefull cycling of the suspension during full and partial steer and full compression and droop I can asure you they do not rub the upper control arm.

As for the fender you are right, you really need at least a leveling kit. or you will rub the rear bottom of the fender. With a 2.5" leveling kit and stock wheels I have no clearance issues with the 33/12.50R20 tires.

Good to know. I guess different tires vary as well. We put a Goodyear Kevlar in that size and the lugs grabbed that control arm. And if you can live with a bit of rub at full turning lock, then that will work fine. I hate with a passion, any kind of rubbing.
Long story short.. I stand partially corrected haha.

Seeing as Goodyear generally runs small to size I find that very interesting!

I guess I should say in theory the stock 275/60/20 is about 33" by 10.8". Every manufactures ruler is a little different
Can't say I've ever actually measured the height/width of the stock tire. I'll have to check it out next time I'm home
