[07'Grizz]

Hello, I'm new to the forum so please bear with me........ I have an 07' Yamaha Grizzly 660. I am looking into putting on Maxxis Bighorn tires in the 26x12 size or the 26x14 size and ITP C-7 rims. I have been compairing tire sizes and weights but haven't been able to find any statistics for rim weights. I have found that the 14 in. tires are lighter than the 12 in.. If the 14 in. rims aren't too much heavier than the 12 in. I will go with the 14 in. set up since the entire package will be lighter and take less power to operate. Plus handleing is supposed to be better. Does anyone out there have a 14 in. set up on there machine and if so how does it handle and have there been any problems?
Any help will be appreciated!!!

Welcome aboard Dan!

I have the ITP C-7 wheels with 26" Mudlite XTRs on them. That was the setup I started with but always wanted to go with 14" tires/wheels for handling purposes. I finally got another set of ITP wheels in 14" and put 26" tires on them. It is not only an amazing difference in handling but damn does it look better too.

I actually really like the mudlite XTRs so much I want to put them back on, but can't force myself to go back to a 12" configuration.

As for durability/dependability, I really haven't had any issues at all. You will find the ride is a little more rough with the 14" setup but not enough in my opinion to make you unhappy with your decision. If you generally do a lot of rocky technical stuff, obviously the 2" smaller diameter won't give as much sidewall protection with the 14" wheels as you would get for 12" wheels. I was doing some pretty technical creek maneuvering right after I got mine and a large log wedged in and scuffed my new wheel. But, I doubt the tire/wheel size combo caused this. Either way, I'm not too concerned.

I hope that helps!

I personally think that there would be a very minimal difference in weights while compared between the 12" and 14" combinations. They are both heavier than stock which will affect performance a little but the additional traction and performance a compromise that is well worth the sacrifice.

Gald to see you here on the site! I agree that the 14" looks awesome, my dad has an 07 Grizz 660 with 14" ss112's and the 27" XTR's and is SWEET! As for handling and performance, I say handling is a little better and ride is a little better with the radial, comapred to my mudlites. However, you will lose some of you bottom end power since you are going to a bigger wheel and tire, and it wieghs more. You can do some other mods and gain you power back if it is that big of an issue for ya! I say "GOPHER" the 14's you will be very happy!

I noticed a difference in power when switching from this (26" Maxxis Mud Bugs on 12" SS108s):

To this (26" Maxxis BigHorns on 14" SS112s):

The difference wasn't extreme, but I could notice it. Or maybe it was just me??? However, adding simple weights to your CVT can correct power issues. Or you can go all out and install a clutch kit.

i don't know about the different wheel sizes, but I do know that Griz looks SWEET!

Here are some of mine with the 14's.
