Re: \'06 John Deere Trail Gator
I have ITP Mudlites on my 2005 diesel Gator. They are larger in circumference and much more aggressive than the stock tires, and I can perceive no loss of power with them. That said, I have not had the stock tires on this Gator. I demo'd a gas model and decided on the diesel, but I think either would handle a moderately more aggressive and larger tire fine. The one other thing to think about: I went with the same size all around, rather than the smaller fronts as with the stock Gator. It really enhances the look and adds a bit of front ground clearance, plus you can rotate the tires based on wear.
