2003 HONDA RANCHER 350 ES 4X4 WITH SILVERBACK TIRES PLUS
So, I would not put 27 's under one odds are you will NOT be happy with the power the atv has afterwards, and might get stuck more often due to not having power to spin and self clean a tire!, plus you can damage drive train having heavier tires, more traction at time son them and, making motor work a LOT harder all the time to move them! IMO< going to any tire taller than a 26 on a rancher is asking way too much from your rancher, there geared higher, and don't have the HP to handle large heavier tires, So your front and rear drive train will not be turning at same speed and will cause binding, and breaking of parts IF tires do NOT slip first!> If so, you should NOT be running tires of different heights to the front and reatr, your asking for drive line problems and or damage!, they need to be of the same Diameter from and back for the 4x4 system to work properly, and not causing binding in things, taller tires turn less revolutions than do smaller one's First off, I am guessing this is a 4x4 rancher and not a 2 wheel drive model, correct?
