I am interested to know if anybody has put tires on there 300 other than stock. If so, what kind, and how did the 300 handle them.....rob any power, etc.

 

If your worried about loosing power then you might want to stick with the same size tire, but get one with a better tread design. I always felt the 25" bearclaws would be a great tire for a 300 prarie.
I put 26" mudrunners on my 400 4x4 prarie and they did drain some of my off the line zipp. I also cannot slide the rear in a corner like I used to.

 

In 2013 I put a set of Sedona Mud Rebel Rear Tire
Color- --, Size- 25x11-10
SKU#179537
purchased from: Motorcycle Superstore [CustomerSupport@motorcycle-superstore.com]

So far they have been great.

 

What are the stock size on your 300? I put 26" Maxxis Zillas on my last 350 Grizzly/Bruin and they ran great . I'm sure 50cc more is not going to make a difference in power.
Stock the 350 Grizzly has 25".

 

I believe the stock size was the 25x11-10. I no longer have the originals to verify.
