Well on the RZR as much as i like BHs and BWs i like the PB Growlers in the snow way better so i ordered a set last week in 27.5x9x14.. After last Saturdays ride i finally got all the ice melted off of her and put on the new tires today… Looking forward to our 14th annual New Years Day ride on Friday… Will be cold with low of 5 and high of 20 degrees….
