Default 36x13.50R18

I wanted to run 18'' Ultra Magnus Wheels on 36x13.50R18 KM2s with a 3'' TF lift.
I am unfamiliar with the 13.50 wide, is there anything special i need to do to run these?

whats your backspacing? 4.5 is what you need or get some spacers

Extra backspace and a rim in the recommended width for the wider tires. Shouldn't be too much of an issue.

I have that wheel in a 20" with KM2s with roughly those same outside measurements, so Ill give my input.

First. Do you have the wheels already?
If not, read my thread regarding that wheel.
You may not find it anywhere.
ULTRA MAGNUS WHEELS



Next, you will need to do quite a bit of cutting and replace or chop your fenders to fit the tires without cutting them up and rubbing.
Mine rubbed badly and tore up my tires, and my 3" lift is over 4".
Spacers are not necessary with the right backspacing, but you will have to look at what wheels you can actually get with a spacing great enough to put your wheels where you want them to sit.

The only 18 inch Magnus wheel with a JK bolt pattern has a 5"BS with 0 offset.
All Magnus wheels are 9" wide except for the 22s which are 9.5".


My adapters act as 2" spacers, but I actually got wheels with a positive offset (+18) that would suck them back in over the adapters and place the wheels and tires at the width I wanted, whereas most people prefer a negative offset to push the wheels further out. .

Just make sure the wheels are at least 8.5" wide. I considered thpse tires but they won't fit on the stock wheels. BTW, by the time you install them they will be close to a true 35".

also what from bumper are you running, if its stock you will have to remove the air dam or you will rub, maybe even have to cut the rock rails if you have a rubi, i know joey2times had to do it with his 35's
