bigger tires on a mule

[ffemt1271]

What is the largest sized tire that can be put on a factory 4010 mule without a lift kit. I am about to purchase one and need to pick out some tires. they will only be installed during hunting season, and i would prefer to stay away from a lift. Thanks

i purchased a mule yesterday, and for reference you can put 25'' tires on that are the same width as fatory without rubbing or a lift
