Finally Decided, New Wheels/Tires

So I think I've finally decided on a new set of wheels and tires to go on the commander after a 2 inch lift.

I want to go with the Nitto Terra Grappler 275/65/18's on an 18 inch kmc rockstar rim.

Those tires specs are 32.1 inches in diameter and a little under 11 inches in width. What are your guys thoughts on this tire? I would be running them with 1.5 inch spidertraxx. Also, I need some help getting the right offset/backspacing for the wheel, can you guys help me out?

I can definately help you out. But first I have a question for you. Why would you want to run wheel spacers if you are buying new wheels. If you get the wheels in the proper back spacing/offset, spacers are not needed.

Give me a few minutes to do a little research and ill let you know if the rockstars come in a back spacing that will work out for you. Also just so you know, with that tire size, youll definately have to bend over the pinch weld and trim or re mold the plastic inner fender well.

Ok. The KMC Rockstars come in a 18x9 in the 5 on 5 bolt patten with +0mm offset (5 inches of back spacing). With that wheel/tire combo (275/65R18), you would stick out about a half inch further then guys running 265/70R17's with 1.5 inch wheel spacers.

Here is my XK with 265/70R17's and 1.25 inch wheel spacers. That setup with the KMC's would stick out 3/4 of an inch further then mine.

Awesome man thanks alot for the help, and to answer your question, I just figured I would need the spacers so i'll definitely be happy saving the extra money if i don't need them. Would there be a problem clearing the ball joint bolt with no spacer? I have mine ground down already but when I put the lift on I'll have to buy new bolts and grind them down again if I need too. So what do you think about that setup then? Its hard work finding an aggresive looking tire that will fit and 18 inch rim and still fit on the commander.

You wont have any problem clearing the ball joint bolt with that setup. If you decide to replace the ball joints, you wouldnt even have to trim down the bolts againit as you will have plenty of room. Also, you really shouldnt have to replace the ball joint either. Just use an impact to get the nut off.

I think that setup would work out really well. Like I said earlier though. You will definately have to bend over the pinch weld and do a little trimming. Do you mind if the tire/wheel combo sits out that far? Some guys dont like the tires/wheels sitting out past the fenders. Honestly, I think it would look awsome!

Perfect just what I wanted to hear, I definitely don't mind if the tire sticks out a little. What if I used a 1 inch or 1.25 inch spacer, would it give it more clearance in the wheel well?

No, it wouldn't give you more clearance in the wheel well. It would make everything sit way to far out though and you would have crazy rubbing everywhere when turning. Not only that but there would be a lot of added stress to the wheel bearing and other parts.

No spacers needed and won't push the wheels beyond the fender, which seems to be the cause of tire rubbing on the XK.
