What are the minimum changes necessart to run these tires/wheels?
Found a possible deal on a set of Wrangler MT/R 33 x 12.50 r15 tires with 15 x 10, 5 x 5.5 lug pattern wheels with 3.75 backspacing. Owner is going to larger wheels/tires and is selling these cheap. Looking to find out the minimum I need to do to my TJ to run this tire/wheel combination.
I've read so many threads about lifts that I am suffering from "lift overload". There appear to be so many options that I am confused. Looking for some suggestions...
At this time I'm going for the "look" over the "function". Will not do any off-roading or rock crawling at this time but might change my mind later.
Current suspension setup is stock with the following: Dana 30/186MM Front Axle, 3.07 Rear Axle Ratio, Dana M35/194MM Rear Axle, 4.0L I6
I know I'll need adapters/spacers to account for the 5x5.5 lug pattern but not sure about the rest.
Thanks in advance for your replies.
P.S. Also found a deal on a set of 5 wheels/tires off of a 2013 Wrangler. They are 16" factory rims with Goodyear Wrangler ST 225/75 R16 tires. These are 1" bigger than what I have right now but don't have the wide track look that I'm going for. May buy these as a backup set since they are so cheap.
I wouldn't do it personally, but with all that extra backspacing you might be able to make it work with no lift. With 3:07 gears you are going to lose a lot of power running 33's.
This is what is so confusing. Most of the threads I've read say that you are OK going up to 33s without worrying about the gears. Only when you go up to 35s or 37s do the gears come into play. What king of power loss am I looking at? 10%, 20%, more?
Right now I can pull out in traffic and get on down the road with no problem. I have more power than I need in most situations. A loss of 10% would not be an issue. A 30% loss would be a problem. Are there any charts or graphs that show this power loss through each gear?
A regear for 33's is pretty common if that's what you plan on staying with. And most people just deal with the power loss with 33's. I have a 4 banger with 33's and 4.10 gears. 1st-4th is fine. 5th is pretty much a total loss on uphill climbs and I top out at about 70-75 without any wind. But I didn't get this jeep for speed
But to your question about power loss. I've heard the 3.07 gears are a dog on the highway. But if you're worried about it, why not see if you can get some 32's instead? Especially since you don't plan on using it offroad. It'll give you the look with slightly less power loss.

IMO, those wheels would concern me. A 10" wide wheel with 3.75 backspacing, plus the added inch or so from the adapters, is going to make those tires stick out goofy far. Just curious if you have strict tire coverage laws in your state?
If it were me, and a deal that could not be passed up, I would sell the wheels and get some 15x8's with the correct bolt pattern.
This is how far my old 33x12.5 tires stuck out with 15x8 wheels, 3.75 bs, and no spacers. Not sure how wide of a look you are after, but I thought mine had a good stance back then.
TJDave, thanks for the pic. Puts things in better perspective. Maybe the best idea is to pass on the 33s and look for 32s or even 31s. I've seen the "goofy" wide tires on Jeeps before and certainly don't want to go that far.
