Can't decide on tire size, need advice.

I have a 2015 Rubicon X or Hard Rock ordered and I am going to put different tires and wheels on it. I will leave the suspension stock and am wanting AEV Pintler wheels. My question is tire size. 285/75/17 or 305/70/17. I don't want to do a spacer lift and I don't mind trimming the lower air dam if I have to.

The lions share of my off roading will be in the sand, so a lot of flex, beyond stock is not an issue for me.

I am old school and just want a 33x12.50, but metric sized on a different Jeep than what I am used to is throwing me off. I don't want to big or too small.

Thanks so much for your advice.

I believe that the 285's are about the same size as 33's. Even 33's aren't 33 inches tall most of the time. They should be safe even with some flexing. As far as I can tell, the Pintlers have more backspacing (they position the tire closer to the frame) than most aftermarket wheels. 4.5 is ideal and those have 5.2, I think. Maybe someone with Pintlers and 33's will chime in.

You could run the 305's but you might rub when flexed but you could run 35's with properly backspaced wheels on the street and mild trails with no issue. If you're wanting to get rid of the rake but not get much lift, try a leveling kit. Teraflex and Rancho both have good kits that won't affect geometry enough to worry about.

Wait, you have a 2015 Wrangler?

It's ordered. Like I said, I have decided on the Pintler wheels, just need to decide on tire size.

Pictures would be awesome as well!! *hint, hint*

I have a 14 rubicon with Pintlers and 285/75-17's which are true 33's and actually marked 34x11.5 on the tire. I can tell you from experience that you will need a little lift and for sure you will need to trim your air dam and they will be pretty close to your bumper ends. They are much more then 2" larger then stock in real life. I think they are a good size for most situations.


without a lift and proper bumpstops you will be rubbing like crazy on even mild stuff.

That is the exact look I am wanting. Do you have a lift of some sort?

I just figured out that a 295/70/17 is almost an inch shorter and about a half inch wider than the 285/75/17. In that size, I have found a couple tires I like. From what you have said, that may solve my potential "might need a lift" issue?

I also found a couple 33x12.50x17 tires too, but the width may be a problem?

jadmt what size bump stops would you recommend for a 285/75r17 with a 1.5- 2" lift?

You need at least 1.5-2" lift. Mine is 2"

You could do the stubby bumper conversion from VDP, cut the flares to make them flat and trim the air dam. If you already have a jig saw and reciprocating saw then your cost is only $65 for the stubby bumper end caps.

May not need to do the spacer lift then.
