I recently banged one of my rear wheels on some rocky terrain and there is a leak near the bend in the rim. I filed it with slime and aired it up and it's holding OK, but I'm looking to get it replaced before winter as I'll be using this machine to plow. What is my best option? I can't seem to find a stock POlaris rim on line anywhere. Delta Steel wheels seems like a good replacement but are the offsets the same as stock? I believe stock is 5x3 and I can't find a the same offset. also to confirm the bolt pattern is 4/156 right? I'm not home to measure currently.
