When it comes to your EZGO RXV Golf Cart, they are the most forgiving in terms of being able to fit taller tires on a stock ride height (without a lift kit) installed. But to go above 20" in tire size, your EZ-GO RXV will need a lift kit! EZGO RXV golf carts can fit the following tire sizes depending on whether or not they have a lift kit installed:
Up to 20.5" tires with no lift kit installed - (all normal non-lifted tires sizes + these taller tires will fit stock: 205/65-10", 215/50-12", 205/30-14", 20x10-10")
Up to 22" tall tires with 3" lift kit installed - (which means with a 3" lift, even taller tires will fit: 22x11-10", 22x10-10", etc.)
Up to 23" tall tires with 5" or 6" lift kit installed - (the tallest tires will fit with these lifts installed: 23x10.5-12", 23x10-12", 22x10-12", 23x10-14", etc.)
