I just found this board, and have received a ton of help from Cory so far.

I have a 89 v-6 extra cab, and I'm putting a 4" suspension lift on it...any suggestions on the perfect wheel/tire size combo to complement the lift?

I live in Western Montana and do an ample amount of off roading, and highway driving.

Thanks for any help you can give me with the wheel/tire question, and thanks again Corey for a GREAT web site.

 

33x12.5s

I strongly reccomend re-gearing your differentials to 4.56 so Your speedometer, odometer, and general driveability don't suffer. If not you will have acceleration problems.

 

What he said. The 33s will fit just right, you cannot go any bigger without a body lift or trimming your fenders.

 

35's with a 2" body lift added, otherwise stay with 33s. I'd actually go with 5.29s if your going to regear.
