Wow, what a difference! I put a set of Goodyear Tracker P's off of a Sportsman 500 (family member) on my Magnum 500 and am very pleased with the tire's performance in mud.

I used to have the Trackers on my Sportsman 400 and took it for granted that it was the 2 cycle power that was getting me through the mud. Wrong!.
The tires had a lot to do with it.

The original equipment Dunlop KT125s are not good mud tires.

The Dunlops offer two advantages only, a soft ride
and directional stability.

Other than that, The Dunlops are puncture prone and do not provide enough traction for the heavier Magnum in muddy conditions.

I'm glad I switched. I was starting to think that Mag 500 was not a mudder. No wonder Polaris puts these on the Sportsman 50o as standard equipment.

 

Thor, im glad the Goodyears worked good for you. I did not like the Dunlops that came stock on my Kodiak,i replaced them with Goodyear Mud Runners what a huge difference!!! The only good thing in my opinion about the stock Dunlops was the ride.

 

Exactly.

The Mudrunners are what Odin put on his Sportsman 500 HO. 26 inchers all the way around. He was negotiating mud holes with no problem at all over the weekend.

I got his "take offs".

 

Odin and Thor...mythological gods...no wonder you ride Polaris!!!
