This question has probably been answered here several time, but I can't find it through a search. I am looking at getting new BFG's for my X. I got what I thought was a great deal on a set of Sahara 18" moabs, so I sold my 17"s to my son. Now I see that the 18" tires are limited in sizes and also more expensive. KM2's come in 2 sizes for 18" wheels LT305/60R18 & 35X12.50R18 how much difference is there in the 2 & will I need lift or spacers to clear them?

 

The 305/60R18 works out to be 32.41" tall by 12.01" wide and should work without the use of lift and spacers.
To run the 35" you will need a lift and wheel spacers or you could use flat flairs and wheel spacers if you prefer.

 

I have 1.75" front and .75" in rear just to adjust the rake due to my bumper and winch. Will these allow me to mount the 35's and get by on the street until I add the 2.5" coil lift later?

 

Wow! sounds like the 35"s are some big guns, I might stay with the 33's, since I drive it more on the streets than trails....thanks for the advice but I'm still gonna get the lift.. don't tell my financial advisor (a.k.a wife) I don't really have to have it

 

You don't say whether you have a 2 or 4 dr. I have a 4 dr with 35's and really regret it. I should have gone with 37's. I can't imagine going with a small tire like a 33.

 

I have a 2 dr. Is there a difference in the clearance in the wheel wells or are you talking about the appearance due to the size difference of the 4 dr?

 

Kewl! just got a call from Shrockworks my sliders are ready. N2 are those Shrockworks sliders on your rig? If so how difficult are they to install? They want $227 to install them there. I'm no engineer, but I think I can put these on.

 

I'm pretty sure stock Sahara's tires measure close to 32"
If you are getting it lifted I would go with the 35's

 

Nope. It's just that the offroad performance of the 4 dr is better with the 37's and since the vehicle is bigger the larger size just looks right.
