I have had the ill fate of braking an axle due to a heavy a tire/ wheel combo. the combo was XTR with 14" rims. you just have to choose a tire wheel combo with less rolling resistance. But unless you spend a lot of time in the deep mud as most do down here than go with a milder tire.

You are absolutely correct. A taller tire/wheel combination changes your gear ratio. It is pretty difficult to find larger tires and after market wheels that weigh less than the factory sets do. If you go to a radial design you will add more weight. It is really up to the owner of the quad as to what he or she wants. I have had experience with issues caused by going too big in the tire and wheel department and was just passing on the information. With 27" tires on a 420 Rancher you WILL see a pretty substantial loss in power the first time you drop off into a large mud pit. I will add, the larger/heavier wheel tire combination can cause added stress on the drive train, clutches and etc.
