I want to upgrade my tires to the Mud Lites 27" 10 x 12 front and 12 x 12 rears, Are the 27" to big for the Grizzly? The dealer says to only go one size up to the 26" is this true???

No this isn't true! You can run tires up to 28" without problems. The reason most people run 26" is that it keeps the gear ratio closer to stock form and still gets you the deep lugs. Think of it this way, the 27" tires give you 0.5 inches more clearance than the 26" tires. However, you increase the unsprung weight and make the "gear ratio" higher and therefore make the low range higher so when you go to accelerate from a stop it takes more gas to move both because of larger tire (gear ratio) and heaver tire.

With all that said, if you do lots of mudding and don't care about the acceleration and use low range more than high then get the 27" tires and Love Life!! I used to run 27" 589's and they were AWESOME in the mud!!! however, they were not the greatest for trail riding or speed runs hehe...its just a matter of picking what you want.

I like the 26" because its kind of like the best of both worlds for me as I do 25% mud 50% rocks and trails.

Enjoy your ride!! and welcome to the forum!

I have 27" Mudlites and C5 rims excellent choice of tyre and rims, Ride is much better than stock, goes anywhere through anything. You do need the overfenders or u will get covered in mud etc!!! The 27's do rub on the black plastic behind your feet at first when the springs get compressed but the tyres wear the plastic down on the first hour of hard riding and make a perfect shape (better than trying to cut it yourself).
I have already trashed one of the front bearings I do not know if it is because of the extra weight or because half of the time the gizzly is up to the lights in water!!!! But beware as it is only a couple of months old with 1300kms on it. Dealer is fixing on guarntee so I can't complain.

The T5 rims are more durable than the stock ones for sure!! Dont get the T6's as they are "finshed" and look better but are not as hard a metal and dont have the beed protector that the T5's have.

You cant go wrong with any choice of aftermarket tire as ANYTHING is better than the paper thin crap that they call stock tires..

Tindy,
I see you have a 05 Grizzly. My only advice to you is that if you have a warranty, watch the bigger tires. Yamaha will not cover problems with your ATV if they know that you bigger tires on it. Remember that bigger is not always better.

Just broke a rear axle on my Grizz over the weekend and I placed my 25" tires back on for when I take it into the shop. Hopefully they won't say anything about the HMF exhaust and they have no way of knowing about the clutch kit. Anything else I have done should not be a warranty stopper.

What did you do to break the axle? I run the **** out of my '02 and I haven't had any major problems like I hear on this board.

Went to cross a small stream in 2wd and the machine just sunk in the mud and I stopped moving. Put it in 4wd and then noticed that my right rear wheel wasn't moving. It must have been ready to go because I wasn't on it at all. But I have been before!!!!

Tindy i think you should go with 26 inches tires But i'm not sure about the mud lites. I have 26" mudzilla's and love them, i do a lot of mud riding. You know what they say, GO BIG OR GO HOME.

Thanks Big Gun for the suggestion. I'll think about it. Ask your wife (zia) when she'll let you go riding again. We need to get out there soon....Nice machine.
