After the clay mud kicked the stock tire's butt, I figured it was time to step the game up some. Stock tires were 25x8x12 front, 25x10x12 rear. I chose a Maxxis Zilla 27x9 front and 27x11 rear. Got em mounted yesterday.

Bump this....

 

I put 26" Zillas on my last 350 Bruin/Grizzly and notice no power loss. You have to go 26" or higher to get the 1.19" lug.
They are the lightest 6ply tire out there , your new 27" probably are the same weight as your old 25" tires if you looked it up.

I may get them again for this 350 I bought, I sold the other 350 Grizzly with the 27" Zilla because it did not have IRS or Diff lock.


Your old tires do not look bad BTW. Sell those.

 

Like some other folks have said, I never new the Chinese made such a large ATV....surprizing. Have you got all the "bugs" worked out of it? How is it holding up/performing?

 

At least they picked a good quad to copy. I think they made a Rhino clone too.
