The trackmaster I ran a 100/100-18 rear, but the 100, 110, and 120 rear will fit. The AC-10 I have a 110 rear and its much bigger than the 100 trackmaster. I think I'll be going back to the trackmaster rear after the AC-10 is gone, for the $20 price difference it doesn't perform any better or worse. The front AC-10 I DO NOT LIKE in the soft sand and its kinda sketchy in mud. Its fine on pavement. The Kenda776F front is a much better offroad biased front tire than the AC-10. Its only pavement drawback is it is quite loud.

 

How do those two rear tires compare in size to the stock 603?

 

I have 500 miles on a set of AC10's great tire in the soft sand of the jersey shore. They also seem fine on the street and in the rain. If any body needs stock tires, I have a set you can have.

 

The 110/100 TM is pretty close to the stock 4.6 Dunlop 603...I think 4.6 is the width in inches of the Dunlop, so 110mm TM equals about 4.3-inches wide...I just put a new 110/100 TM2 on the back after running a 100/100 TM2 and already am thinking about going to the 120/80 TM2 (I think they come in that size) as I do not notice any width difference from the 100/100, but I definately notice a height difference. I went from touching with the ***** of my feet to tip-toes, but it may mostly be the new *****.

 

Stock tires ,eh?

What kind fo condition are they in?
How much do you want for them?
Where are you located?

 

The AC-10's are better in sand than stock, but not as good as the 776F. The AC-10 I've had washout more times than the 776 and it never feels quite as planted as the 776 did. That might have to do with its more rounded profile than the wider more square 776.

 

Dunlop D0606's with the new titanium and kevlar cord, sticky 5ive-Ten puncture proof Sleath rubber compound - killer performance and major longevity!

 

Hmmm....So maybe the 606 or the Kenda's....

ac-10 rear might be an option, but I dont like what I'm hearing about the front.

 

I can't wait for the Kenda K-270 tires to wear out so I can put another Dunlop 606 back on, but the way the Kenda is wearing its going to be a couple of years before that happens. [&:] I really liked the 606. I have 1500 miles on these Kenda tires and they still look new. Sheesh. I mean yea that's good, but I need an excuse to get another 606 on.

 

I don't have the patience for that. I yanked those k270's off my bike after about 1000 with plenty of tread left and put on TM-II's. I ended up giving the K270's to a friend.
