You guys may get sick of me but your so helpful.
Ok 2001 sportsman 500 ho. What is the factory tire/wheel size? The quad I bought had new tires and wheels and they are Front- 26-9-12 & Back 26-11-12. Since they are not stock does anyone see a problem running these? They feel fine and don't rub but don't know if they could put undo stress on quad.
Since I'm on the subject they are G-Force slammer wheels with STI Mud Trax tires. They look good but I'm more concerned with function and durability. Any opinions on these.

Thanks again.

 

Stock size is 25-8-12 front rear is 25-11-10. I don't think you will hurt anything running these tires, they aren't much bigger than stock. However anytime you ad a more aggressive, heavier tire. it will put more stress on drivetrain parts. I am not that familiar with that tire.

 

The guy did you a favor changing the back 10" rims with much more common 12" rims.

26" and 9 wide are fine on the front. The backs have alot more room to spare and your width is still stock 11" anyways.
I,d just but them on and go.

The stock rims of the 2001 are steel so if the new rims are alloy they should weigh the same even with the larger 26" tires on them.
