Re:tire sizes for rzr 800
redbrutejr, as several folks have told you, you can run any front to back size you want with that lift. On side x sides I recommend skinny/wides for most applications. Also why are you running a tire like a Mudlite with a 5" lift ? If you plan to mud ride at all, you might want to consider a tire that will really do good in bad mud. If you would like to chat about tires, please give me a call at (800) 699-0947, ext. 6038. Thanks !!!
