2002 griz 660 - needs new tires

1403 Views 10 Replies 9 Participants Last post by  Madkawi750
So My 660 Grizzly is ready for a new set of tires. I am strongly considering a set of Grim Reapers to install on my factory steel rims. I am also planning to go oversized from the stock 25x10x12 rears and 25x8x12 fronts. Just wondering if the added weight and size would be detrimental to overall performance. The size i'm considering is 26x11x12 rear and 26x9x12 fronts. I know the 8 ply of the grim reapers almost doubles the tire weight. Also wondering if a should expect any clearance issues. Any comments are appreciated!

I don't have a 660, but the Kenda HTR's I just put on in 26x11x12 weigh about 2 pounds less than the Grim reapers in the same size, but a LOT more than the stock 25" Dunlop's. I haven't been able to test them on dry ground yet, but everything Iv'e done so far in the snow and on my sanded driveway seems like that size and weight increase had little effect on my 700. Don't know if this helps you any, I'm sure others will chime in soon.

THANKS FOR THE RESPONSE. Well I received my Grim Reaper tires yesterday and am now concerned I made the wrong choice by going with the oversized 26x11 and 26x9s. not concerned about the height but the width of these tires seems much greater then the stated widths. the fronts measure 10 inches wide and the rears are 12 inches. Keep in mind these are unmounted at this point. I find it hard to believe the widths will pull in to the stated specs once mounted and inflated. Especially with the low inflation pressures generally used on these tires. Welcome any input!
I can tell you right now you are making a bigger deal out of this than you should. Measure the difference of the inside width and the outside. There is probably going to be a good bit of difference. That sidewall is going to straighten up and the difference is going to be remarkable. Also, if you would message me, I am curious about what made you go with grim reapers.

X2,

Grizzcrazy is 100% correct! You can't make too many conclusions until the tires are mounted and properly inflated.
You did not make a bad decision. Once you ride on them you'll wonder how you ever lived without them before.
Agreed. The tires will be fine. And if you notice a difference in low end performance, we can help with that also. 30 or 40 bucks and a little quality time with the griz and beer fridge will get your low end back (if it’s even an issue). You’re in good hands here at GC.
Just a follow-up. Got the 26s mounted and installed today. They look great! Haven't tried them out yet aside from driving across the yard a few times. Were expecting 3-5 inches of snow over the next day or so. Should be fun

Looks good let us know how they do
The Grim Reapers look great on your machine. We look forward to hearing your opinion of them on the trail.
Love the looks of Grim Reapers. They are not a tire any local shop carries and would be a special order with ZERO discounts, so they’re insanely expensive here.
If you want mudiltes, bearclaws or Zillas the local places have lots and offer 40% of retail on them, anything else and you’re out of luck unless cash flows from you like water.
