35x18 or 37x20?!

I'm trying to decide between the two.

Looking to go with a 3.5 or 4" lift depending on the tire size, any photo reference help would be greatly appreciated.

Neither! Unless you are going for the ghetto hoopty look.

Neither 35x18 or 37x20 would be relatable to your aforementioned picture...

For instance:

3.5" - 35x18





4.5" - 37x20

Less rim, more tire is better for off road use. 37's will require new gearing, beefing up your C's and sleeving the front axle on the JK's. It really depends on what you're looking to do with your Jeep.

Check out this thread...lot's of different set ups to check out -

I've heard about 37s requiring new gearing -- ballpark, what would something like this end up costing?

Prolly around $1,200-$1,500. That would be gears, master install kit and labor all in. Check with some of the local shops. Make sure you put a couple heat cycles on them before a long trip. Swap the oil out at 500 miles.

35's on 18" wheel
37's on a 20" wheel
I have 35" on 20" wheel and it could use more sidewall, but works fine for what I do.

I have a 4" with flat fenders. I'm running 35" nitto trail grapplers on 20" rock star.
After seeing that black 4 door with the mud grappler, I will be getting those 37's next!
