Tire Differences
Tire Differences
My '93 KDX currently has a rear Dunlop D756 100/100x18 and a front Metzler Unicross 90/90x21. Buykawasaki.com has the factory of 100/100x18 rear and 80/100x21. In looking into getting new tires I am looking at a Michelin S12 front and M12 rear. The 100/100x18 I have not found anywhere yet so I am asking what the differences are in a definition sense of say a 130/18x18 and a 120/19x18. Is the tire descriptor the same as a car, my corvette has 275/35ZR18 front 325/30ZR19 rear and know that that relates to tread width, sidewall and rim. Also what would be a recommened generalized spec be. I guess I would ask what is the difference between a 130/18x18 and a 120/19x18 and same for front. Advantages disadvantages etc.
Thanks guys!

I think it goes width first and then height percentage to width. 100/80 is 100 wide and 80% as tall. I THINK !

I've done a lot of searching re: "tires". What I understand is that people run the M12 NOT because it lasts longer...but because it grips better. The S12 has a "sideways knob" in its tread pattern & doesn't hang on as well as the M12 in some situations, according to reports - not my "real world" experience!

re: 'I guess I would ask what is the difference between a 130/18x18 and a 120/19x18 and same for front.'
Neither of those are valid sizes. Typos? I don't know.
The tire sizing does fit/relate to automobile tires...namely width first, ratio second, wheel size third.
Where the confusion comes in is the 'old' vs: 'new' method of sizing. At least Michelin's sizing is different. Don't know about other european outfits..like Pirelli.
I finally found another rider (local shop owner..MX racer guy)that has the same opinion as I do regarding the S12. Traction is great...brakes like it's on snot. You actually speed up when you put on the binders! But, throw a roost? Oh yeah. About 10" wide!! Sounds like a newly sharpened rip profile chain cutting the air (chain saw). The thing actually moans!

re:Braking
Again... different schools of thought on this too!
85% of effective braking is front and 15% rear. This is my school of thought and found this true of street and dirt. The rears have to have some effectiveness but not nearly as much as the fronts.
