I bought an 2011 RZR LE with the 12" Aluminum Wheels and would like to upgrade to the Bighorn tires which will add a little width to the 50" RZR. My question is, should I get 12" bighorns for the stock 12" Rims, or buy new 14" rims and 14" bighorns to go with them. I ride mountain trails in WA. If the money wasn't an issue, which will have a better ride, the Bighorn 12" or the Bighorn 14". Conventional wisdom tells me that the 12" has more air and less wheel and should therefore have a better smoother ride over rough rocky trails. Anyone know the truth?
