Get at least one size larger than you need when it comes to Zillas. My 27's are 26" It also plays a part in the advertised weight department. They are light, but not as light as they say.
So I should just buy 30's for my 360 prairie??? That should really kill it , it's already a dog.Do it right...just buy 30's front and rear like mine! They are low profile but one of the best mud/stable flotation tire out there!
