Picking up my 570 tomorrow and wondering if I should go with 28 or 29.5 ol2? Or should I go origiginal outlaws. Plan on using stock rims if possible. If anybody is awar if I can use stock rims with no rubbing please let me know. Also do they make hotseat or looney tunes slip on for the 570?

Haven’t had a quad for 6 years and also wondering any other tires I should look at maybe that would be the same size and fit also
