Right now I have this wheel http://www.ultrawheel.com/wheel_deta...brand=1&id=146

I have the 18 inch wheel.

Mounted on 33'' Mud Grapplers. In the near future I am going to get a 4'' lift. Right now the tire I have mounted is a 33 by 12.5''. I might move to 37'' tires of the same grappler but in 37 by 13.5''. So my question is do I have to sell my rims or can I mount a 1'' wider tire on them?

I know this is a really stupid question this is just my first Modded "Offroad Vehicle" and I dont know much about cars because I'm in highschool and this is my first car and my Dad does not do anything car related. And no I'm not just some spoiled rich kid I did myself pay in full for my jeep and all other offroad parts.

 

I think you sould be ok with the rims you have. Not a hundred % sure but thay should work.

 

That wheel is 8.5" wide. A 13.50 should still fit, although that is probably as wide a tire as should go on there.

 

per Nitto's site for the 37x13.50R18 Mud Grapplers the approved rim width is 8.5" to 11" so you are good with the rims you have.

 

thanks for the help

 

Yes they should fit, and another thing. Please don't ever call a Wrangler a car.

 

LOL... I don't care who you are... that's funny!
