Tire sizes, confused

[tony27]

Sometimes you buy a Michelin that has a sticker on the sidewall that has the "normal" size on it.

Michelin 120/90 = everyone else 100/100.
Michelin 130/80 = everyone else 110/100.
Michelin 140/80 = everyone else 120/100.

Yep that's correct..
It seems as though the enduro tyres use the different measuring system and the mx tyres the conventional way.
MH3 and MS3 are 100, 110 & 120 sizes

What do you expect from French company

Bugger I wanted some S 12 for my little KX and went with Dunlops because I didnt think they made a small enough one.

A little off the track, but while close to the subject,
Not a hell of a lot of choice in Knobbies for rear 17" donuts,,,,,,,,

But got great surprise and ongoing feeling of satisfaction, with a
Kenda 130/90-17 K760 Trakmaster II DOT Approvd 20% Road 80% Dirt Dual Sport Tire


If anyone has found a better 17" rear Knobby
Or any ideas for a 17" dirt track rear ?? please share

371112319869 ebay number for a Barum 400-18 rear tyre for the older cz. fitted one to my triumph metisse over there in '67, then it rained--saved my day did that tyre, plus the fact that the stator was unraveling & made it missfire so bad that it got more power to the ground lol--well, was my theory anyway.

[Mick D]

Yes, I thought they were ok on my 73 CZ400 too, Still have a new one in storage.
I wonder what their new Mitas ones are like??
Col Moody is a good fellow that has Been around the industry for years,
 I believe he is/or is attached to the Mitas importer?

PS; I am not going to a jab a sharp instrument at my stator to try your ignition theory

[OverTheHill]

yes, stator thing not recommended on a single cylinder or you'll be walking home lol. I had a spare cylinder so she was a 1.5 cylinder. Funny thing was it still barp bar barped its way around  christmas hills fast enough to pull endless wheelies & then get black flagged for it--or disqualified from the results of that race--was well in front in that one too, damn. Pissed down that day or i would have been totaly psyched out--hate dust.

here's a tyre trick i'd never admit too--oh ok--neighbours kids chinese 150 thingy with a bald & flat 12 on the back & no money, fitted a bigger tube & folded it over which worked for ages but the damaged tyre internal cords were cutting through the tube in the end, so [always happens at the weekend when i can't escape], found a 12 pushbike tyre & tube so fitted that with the 300 12 over the top, forgetting it wouldn't blow up to 300 diameter inside it's own bike tyre. Must've put 120psi in before twigging, so let it down to 50 & it's still going 6 months later [worried now], doubled the suspension with a cushioning squash gap between tyres. 'don't tell anyone it was me'!!. Might be onto something there for the 4 & 7 inch suspension rule.
