14" rims

For those who ask about switching from 12" to 14" rims, here are two reasons why you should not do it. Two tires, $340 worth, in 8 months. Just did the 2nd one today. Never had that problem on my X2 with 12" rims. You need the extra sidewall if you ride rocky trails. Both of these happened from pinching the tire on the rim when I hit a rock just right. (or just wrong)

Bob, sure hate to hear that happening to you. Did you have any warranty on the tire? I'm not sure if Discount offered their warranty on the atv line of tires.

The main reason I went with 14" rims was to cure some handling characteristics. And the other reason was less tire to puncture. I haven't had any side wall issues with my set up not even a good scuff. Now the rims have there share of nicks and scrapes. I think there are a lot more variables to consider like tp, tire width at the tread and side wall, tire construction, rim design and dimensions. To name a few.

I run 7 psi in what is supposed to be one of the toughest atv tires you can buy. If my only problem was handling issues, I would use air pressure to cure that, as opposed to screwing up my off road capabilities by moving up to these tire killing 14" wheels.

" I think there are a lot more variables to consider like tp, tire width at the tread and side wall, tire construction, rim design and dimensions. To name a few."

I think I pretty much have all these covered about as well as possible, with the exception of sidewall. Low profile tires and 4x4 just don't mix. These are not high performance sport quads. They are not meant for track type events or sport quad style of riding. These are supposed to be for high performance off road use. If I didn't ride challenging terrain like I do, I suppose they would be ok, but I bought it to ride.

The only other option you have going to 30in tires and then you have to upgrade the clutch, which then you have to upgrade the axles and on and on. Thats too bad those tires should be able to handle your riding style.

I have to respectfully disagree with you...

I believe you're more apt to pinch a tire running 12" rims over 14"-
the more rubber on the side wall, the easier it is to fold & flex.

the biggest problem usually is not enough psi in the tire while riding rocky terrain- the sidewall collapses and gets pinched between the rim edge & the rock.
less rubber = less pinch / more rubber & low psi = more pinch & fold.

I've seen it at least a dozen times riding over the last 20 years- a lot of people who ride these rocky new england trails drop their tire pressure for a smoother ride, but end up folding the sidewall and slicing it open. especially when you're running tires 26" or larger on 12" rims- you need to stiffen up that sidewall with maybe 10-12 psi to prevent it from folding.

If anything, proper tire pressure for the riding style & picking a good line over rocky terrain has more than anything to do with these types of punctures than rim size by itself. I'm thinking you probably just ran into a bad circumstance.

(sorry about this being my first post on the site- I'm a long-time member over at atvconnection- same screen name, and we were discussing this same topic in a private forum over there and one of the members posted this link )

polaris axles will easily handle 30" tires- but the clutch upgrade would be a good idea.

Yeah ur not going to get certain characteristics buy upping the tire pressure on a 12" rim compared to running a more normal/lower tire pressure on a 14" rim. And homeboy u ain't the only one riding technical trails. When its time to pick it up we blast and when it gets dicey we crawl.

I've got your homeboy hanging bp. If you have nothing constructive to say, perhaps you should just keep to yourself.

Hey beergut, recognize you from there. I know in my years of riding the same trails with my X2 and 12's, I never had these problems. When riding my wifes 500 with 26" BH's on 12" wheels at 4-5 psi, I've never felt a hit that was enough to cause worry. My point is, same rider, same trails, same riding technique. The only difference is the wheel/tire combo. Since moving on to the XP, several times every ride you can feel the hard hits that worry you about pinch's. I run a minimum 20% higher pressures in the 14's than I ran with the 12's. I'm frustrated and irritated right at the moment. It's not about the money, I can afford the tires easily enough, it's about being broken down out on the trail.

Anyway, the whole reason for this thread is to give those who are questioning a wheel swap something to think about and consider. I'm not going to sit here and argue with everyone. I have stated my thought's on this matter several times, and have posted this as supporting backup. Take it or leave it. The proof is in the pictures.
