Since there is alot of talk about tires lately I figured I would take some measurements.

Stock 650 tires:
25x8x12 25x10x12
24"x7" 24.5"x9"

589 MT's mounted, but not on wheeler with 5 PSI
26x9x12 26x12x12
26.25"x9.25" 26.25"x10.5"

These measurements were taken by me using just a tape measure. It would be nice if anyone else with other brands/types of tires would do the same. Most tires from what it says on the sidewall to what they actually measure is two different sizes.
Thanks, I hope this helps someone.

 

Mudzilla 28x8-12 are 27" tall, 8.5" wide,
Mudzilla 28x10-12 are 27" tall 10.5 wide

They have huge rim protectors

I want to repeat this one fact for all the 650 owners concerned about needing a lift kit:

My front tires have rubbed slightly about 4 times or so. I do not think I need a lift kit. It is insignificant.

Other other thing. ATV news says these tires are 28" tall. Not for me, not that tall.

My quad did gain a full 2" ground clearance. These tires don't pooch much.
