Ran over a rock on the weekend and sliced another sidewall.....Have new big horn tires, dealer told me to run around 8 psi in them. Think I pinched the tire with the rim because there is two slices one above the other. Have 14" rims from polaris, could it be the bigger rims causing the problem this is 3 tires in the last year.

Boy, do I know what you're going through. I went through 5 bighorns in the last year myself driving in the rocks around here. The rocks sure are big and sharp. :rm_thumbdown:

I noticed I have a bad slice in the sidewall of one of my bighorns but it seems to hold air just fine as of now.
They should consider redesigning their sidewall to carry more lugs or agressive patterens all around the outside of the wall to help withstand the sidewall abuse.

I suppose that would cut in on their sales in new tires though. LOL.

I have 12" rims with big horns and logged over 400 miles through rocks and such with no issues. I run between 6 and 10psi depending. If i rock crawled all of the time i believe i'd get a set of 12" rims for that. those 14's sure do look nice, but it pretty much ends there.

I think it is more the 14" rims than it is the tires. I have 14" rims on mine and have pinched my tire twice now. I switched to 12" and put about 300 miles on them and have not had a problem.

i run the 12" rims and big horns out in the arizona desert and there the best tire ive had. and our desert is nasty i run the psi way up so the tires are hard and no problems so you should be ok.

thanks for the replies....my first two tires were not BigHorns, they were what polaris put on the rims, goodyear mts I think. For the latest slice in the Bighorns, we were riding down a trail and there was a rock on the edge that no one saw... 3 out of 6 bikes, (two were side x sides, one atv) punctured their tires....sucks, but I guess thats riding

As already stated, it's the rims. You need to switch to 12"
rims. Otherwise you'll keep having to replace your tires.
I have the 12" rims with Bighorn tires and I've never had
any trouble. My RZR is gen 1 and it's had the Bighorns on
since I bought it, same set and there still in great shape.

You said in your post it was rim pinched, two cuts one above the other, doesnt matter what tire you run, a 14'' rim will do this to most any at low pressure.

Pit bull 8 ply tires .:)
8 plies are nice but how many are in the sidewall? I have not been able to find ANY ATV/UTV tire with more than a 2 ply sidewall

8 ply tire sure is heavy, Eversince I got into utv's in 04 I have run the Bighorns Because they look like the old BFgoodrich Rambo race tires. Ive never had a flat running my Bighorns in the desert I would say it was driver error OR the 14 inch wheel. Eather way it's part of the fun!

5 side wall pinches and 3 new tires in 1300 miles. 14" rims. It sucks when you do it with only 45 miles on a new tire. I have had the psi to 12-15 and have not had the problem since, or just that i have been lucky.

Sounds like it could be pinch flats. Get yourself some 12" rims and problem solved!
What are the geometric factors here that cause this pinching on the 14" vs. the 12" on rocks? I used to run 14" wheels on my ATV and never had any issues. Not really seeing why this would happen, but believe the stories....sucks for sure. Those BH tires are $$. Glad I have the factory 12s now.

14" rims look great but if you ride on the rocks, I dont care what the heck tire you have, YOU WILL GET FLATS! 12" rim and Bighorn all the way for me. 1800 miles on rocks and creeks and not one flat.

I ran Goodyears on 14"for 1500mi. Happier with with the B Horn tires, but a 2" slice in the middle of the sidewall this week end after 800mi does not help the budget.

I am almost convinced that it is the 14" rims however, the two other bikes, (one a rhino, the other a can am atv) both had 12" rims. Guess it was a bad shaped rock that we all ran over. We don't do rock crawling, we ride woods and swamps, and rough trails. We were on the old railway tracks, grown in a bit with trees and taller grass and ran over a tire killer rock. Looking at it on the way back, it wasn't much of a rock, I guess we just hit it the wrong way.

As I mentioned earlier..............SUCKS

I don't know boys but I have 14" rock crusher wheels and now run GBC Grim Reaper 8 ply radials. 14lb recommended pressure ... 1500 miles no problem. Also ran the original (14") Goodyears for 2500 miles no problems other than slow leaks. JMO. I'm not a believer that 14" wheel are the problem ... but hey what do I know ... :)
