When I bought my KRX I bought a spare wheel but without a tire. I wasn't going to buy 31 inch tires from the dealer when I could get 32's or 33's for the same price or cheaper somewhere else. Since I have a bare rim I thought I would measure the offset. The rim is 8 inches

wide. The offset is 6 3/8's x 1and5/8's. The bolts that hold the beadlock ring on thread into metal inserts in the rim instead of the aluminum rim.

What do the stock wheels weigh?

I didn't have a scale to weigh it.

I think big pine did a video on this. They said stock wheel and tire combo is 55 pounds.

Question for y’all. I’m getting ready to buy new tires. Will a 12.5” wide tire be ok?

Interested in this topic as I intend to buy a KRX in a couple months and have been tire shopping. Although a 10" or 10.5" wide tire would probably be better.... but there are a lot of 33x12.50 and 35x12.50 LT tires out there. And not as many 33x10.5 or 35x10.5. Maybe turn your wheel lock to lock and get some measurements? Check to see if some additional tire width would make contact with any suspension components. What tires are you looking at?

12.5 is a pretty big jump and will put extra stresses and loads on suspension steering system.

I’m looking at BFG K02 or the KM3. 33x12.5x15. The factory wheel is a 8” wide. I’m not sure why it wouldn’t work apart from maybe having rubbing issues. It is unlikely though.

Not much difference in weight though.

that 33x12.5 x 15 is a light truck tire, and is going to be a lot heavier and won't have the same sidewall flex as the 32x10x15 KM3 UTV tire carcass which is engineer for our 2000 pound machines, not a 4-5000 truck.

(Above) Exactly!!! I get your thinking with going wider, but you’re changing the whole geometry of the machine at that point.

Good Read on the UTV version:

BFG KM3 UTV Tires

Stumbled across a deal I couldn't pass up yesterday for my KRX. 4WheelParts has a sale on their BFG KM3 UTV tires. $180 off a set of four. Not a lot of info out on these tires, but what little I have found has been all good. Figured that since I was going to go to a 32" tire when I replaced the...

Check out SlickRock Productions. They have some strong arguments against this.

Exactly what Rocky said and the bead on an LT tire is thicker than the bead on a purpose built utv tire. Lt tires are built for high pai and speed/weight. Not low pressure and flexing around rocks etc. Plus a 12”wide tire would gain you nothing in the conditions we put these machines through. Sure you could probably make it “fit”, but why? There’s no good reason.

Not trying to disagree with anyone here and there are some valid points here. As I stated previously, I do believe a 10-10.5" wide is a better selection. However, the LT tire topic is an interesting one. I've owned several RZR's, Ranger, ATV's, and have plenty of tire experience on them. I have never tried an LT tire on any of these machines, but have also read some very positive reviews from serious riders that did run them (on SxS's). If you search you'll find some reviews on other forums. Yes it will have a thicker bead and stiffer sidewall. Likely also heavier (although in some cases, not much at all). But it will also have some durability and tread life benefits. IF I was to ever try a LT tire, it would be on the KRX as it is one of the physically biggest and heaviest machines out there and probably as good a candidate as any. Due to the stiffer sidewalls, the tires can also be run at very low PSI.

Question for those of you that already have the KRX and have changed your tires on them yourself: do the beadlock bolts look long enough to handle a thicker bead? If not I'm guessing a trip to the hardware store would solve that.

Ultimately I would say price. Being in the automotive industry I can get tires at cost. A 33x12.50 is cheaper than a 31x10.5. BFG K02. So in my situation I can get a bigger tire for cheaper. With the benefits of longer tread life. I may be the first to try out LT tires. Because why not right? Lol. If I encounter a catastrophic failure I can’t say I wasn’t warned.
