I tried this in the wheel and tire forum and didnt get any response, so i figured i would ask her since you guys are always very helpful. I am kind of kicking around the idea of buying some 22x10's for the front of my 2wd Expedition and 22x12's for the back, with probably a 285-35-22 up front and a 305-35-22(or a little wider if i can find it) out back. Just wondering if anyone has done this or has any input on this. My current wheel/tire setup is 22x9.5's all around on 285-35-22. I just dont like how the 9.5's dont fill the wheel well in the back, and i would like to get a little more rubber out back for when i build the lightning motor for it later this year.

you would be able to fit a 305 on the 22x10s... you could probably go to a 315 or if you want to get crazy a 345 out back... i think its a good idea, you would have to do some measuring to make sure everything fits just right..

 

I run a 315-35-20's in the rear and 275-40-20's up front
Both are 28.6 overall diameter, but you have to run at least 10 inch rims with these tires.

It drives good with this combo, a little les wandering on uneven roads, but a little more sensitive around corners

 

Thanks for the input guys. I am in the process of taking a bunch of measurements. I know i can fit a 22x11, but if i did that i would always wonder if i could have gotten a 12 under there. I would love to get a 345 on the back for a tire but the problem is finding a 345-30-22, or a 345-25-22 ... i dont think they exist

 

just make sure the front and back tires are the same overall diamter, or your abs will do crazy things.

 

Id like more info on your rear tires please. What brand/make?

This is something i am stuck on right now. The 285-35-22 is stock height ( 30"), the 305-35-22 is 30.4". I need like a 325-30-22, that would be 30-30.2 in. but i dont think the size exists. Back to the drawing board.
