OK here's the back story. Out on run this past weekend. Ripped up front tire on 2015 900 Trail. I didn't have spare ,but used up 10 plugs and limped it back to base camp. I find out this guy has 4 wheels and tires he had from 2013-2014 ? RZR 800 and he's asking $120 for all 4 !!!!!! The next day I look him up and the tires are great at least 3/4 tread and mounted on nice looking rims. I checked out the bolt pattern on my 2015 /900 trail before I left to go and look at or buy the used ones., and checked the spacing on the used ones ,every thing good. So I buy them. Only to find out when I go to mount the used rims that the stud DIA. on my 2015 is, I believe to be 12MM and I am learning the stud dia from the older 800 is 3/8" :rollfinger: So my question to everyone is this. Is it possible to drill out the used rim stud holes from (3/8"..375") to accommodate the 12mm (.472") dia studs.
