I'm fixing to order mudrunners for my P650 26x9x12 and 26x12x12. Will they fit on my stock wheels? Does anyone know how much the stock dunflops weigh? Is there much power loss with the 26-inch tires? Any other comments about the mudrunners would be helpful.

Thanks in advance.

 

Stock Dunflops weigh 14lb front, 17lb rear. They should fit I have 27x12 DD's on stock rims in the rear and 27x10 DD's in the front.

 

Can I add two cents? I like my mudrunners, I only use them in the front. they ride well, steer great.

You won't notice much power loss. However 26" mudrunners are one of the poorest matched for diameter. The rear ones are a lot taller than the front. You can still get them, and pump the fronts up high and leave the backs low to reduce the difference in rolling distance.

Stock wheels are probably good for you to use. It would be better to put the 26" front mudrunner on a 6" wide wheel and the rear one on an 8" wide wheel (douglas makes 6 fronts and 8 rears) to keep the rear tire not so tall. Don't do this with 7" wide wheels all around, you will make it worse.

Lots of people drive around with different rolling distances, it doesn't really hurt anything that we know of. It does create more drag in 4x4. It does make the 4x4 shifter clank louder. Evenly matched tires make steering more difficult. The best thing I know of is to only have the fronts a little shorter than the rear, not the same and not a lot different.

Here is an additional cent. I mounted the mudrunners myself. The are the easiest tire I have ever mounted. I bet you can't get the stock dunlops off, not even if you rent a PA system to cuss into. Mouting tires is a no brainer, and is so easy and fun I look forward to doing it for friends.

 

Thanks for the info guys. I can't understand why Goodyear, with all of their tire experience, would design the tires with a 3" Rolling Cir. difference. Anyway, I emailed Goodyear with the question. If they reply I will post it.

 

My friend with a griz noticed a 4" rolling distance difference in his 27" goodyears.

Their website lists the 27" rear tires mounted on a 9" wide wheel. Ever see a 9" wide wheel on a quad? My friend is still trying to find a 9" wide rear wheel. His are 7" wide I think, and 9" wide would shorten the tire down a bit.

He has been pretty upset at goodyear. My mudzillas had a few inches rolling distance difference until I got them on the right rim widths. Now they are fine.

 

I looked on the Goodyear web site, the rim width in the specs are 6" in the front and 9.5" in back. I take that to mean that there is a 3" difference in the Rolling Cir. with the wider rear rim. If that is the case, my stock rims will make it worse.
Every time I think I have made up my mind on a tire something comes up and screws me up. Maybe I should just go with the Titan 589M/T. They are the same dia. designed to rims at 7 and 8 inch widths. The stock rims would not make that much of a difference.

 

That is a good tire choice. However, I hate to sour you against mudrunners. I think you would like them, it is just that the 26" ones are worse dia matched than the 25" and 27".

I am tickled pink about the combo listed in my signature. It is the lightest 26" set you can get. Totally and completely fun.

 

Nyroc:

I hate to do this to you buddy, but I'm not sure I agree with you on this. Yeah the facts and numbers may indicate otherwise, but I can't see any problems with these 26" mudrunners. MDG: I have the exact same set-up (26x9x12 and 26x12x12 Mudrunners) on my 650's stock rims and do not notice anything. The fronts might be slightly taller, but you can't notice it at all. The 26" overall diameter probably exactly what your looking for, slightly larger than stock....they are taller than stock and the rolling circumference difference is not noticeable at all, in fact I hadn't ever heard about it until now. There was no real power loss I never felt it, maybe 1-2 mph but certainly an easy compromise compared to the traction and weakness of stock tires. The tires don't rub and they steer easier than stock, even in 4wd.

I know that Susex7 put 26x9x12 and 26x12x12 589 M/S's on his 650 and I tried them out last week. Great tire with great hardpack traction, but mudding ability was slightly limited. The mudrunners had great mud ability but its hardpack traction wasn't as good as the 589's. Thats ok cause it fits my riding style just fine...it makes cornering much more interesting when your poking along at 20 mph, bank a 90 degree left or right turn and go WFO with the throttle around it. But thats besides the point.

Now, I just had 26x10x12 and 26x12x12 Dirt Devils put on stock rims of my dads 650. These tires are a hair shorter than stock (compared to my neighbors brand new 650...if you notice the trend, I have infected my close friends and neighbors with the V-twin disease). I was no doubt disappointed with the size of these tires, however they are unbelievable smooth. Too bad they didn't size up. They seem to have a short sidewall and the rears are much smaller than the fronts. But again, there is no ride difference, I can't feel any problems with it.

I guess what it comes down to is that some people may be bothered by numbers and/or looks AS MUCH as performance...and some don't. But they work well...I highly recommend the Mudrunners and do not feel these differences create any problems or drawbacks.

Just my $0.02....later

 

Parker, you may be right. But it would be nice if you measured it and told us how far the fronts roll compared to the backs in one revolution. 2 inches or less tends to not drag much or make the 4x4 clunk much. Maybe your 26" set is a lot better than my friend's 27" set.

My friend's 27" mudrunners rolling distance is 4" different, and causes a lot of drag. He started running 6psi rear and 3 psi front to even it out, but now he doesn't like the pressure high in front and low in back. He put paint on one lug and rolled it along his driveway and measured the distance. I used Miracle whip, cuz it washes off the driveway easier.

The numbers on goodyear's web page tell us that the 26" ones are just about the worst matched, but maybe thats wrong. You know better than the rest of us.

I do know for a fact that Goodyear has done a really crappy job of diameter matching the 27" ones.

 

Parker,

I hate to ask but, if it's not to much trouble, it would be interesting and very helpful if you could measure it.

I suggest mustard instead of miracle whip. You can see it better and it would look more professional. haha

If you can get to it or not, Thanks for the info.
