Sensible Tire Classification
Tire Rating
Symbol
Description
Green circle

Purely a street tire. Excellent road performance in braking, cornering, and life expectancy.
Not intended nor recommended for off-pavement use. Characterized by continuous tread blocking, narrow grooves, considerable rain siping.
Example: Michelin Pilot Road series
Blue square

Similar to a street tire but with much wider and deeper grooving and less reliance on rain siping. Tread blocking may be continuous or segregated into large, close spaced blocks. Suitable for fire roads roads, firm and rocky Jeep trails,any rolling two-track.
Not suitable for loose and slippery surfaces such as uphill gravel, mud, may be difficult in sand and gravel.
Example: Pirelli MT60
Black diamond

A street-legal knobby tire. Characterized by a fair amount of open space between the knobs, which may be small in size. Suitable for easy single track and moderately loose surfaces such as shale, gravel, sand, decomposed granite, etc.
May be difficult in deep, dry sand, deep gravel, and loose deep mud.
Example: Michelin Anakee
Double black diamond

An aggressive knobby which may or may not be street legal. Has very large knobs and equally large spacing between the knobs. Uncompromising approach to off-road traction; suitable for all of road conditions.
Not suitable for road use due to poor life expectancy, excessive noise and vibration.
Example: Metzeler MC360

Might re-space the text portion above, Tom? And add a couple more suggested examples to each catagory?

The text was copied and pasted so folks could easily edit it. The forum won't allow the uploading of a .docx file.

I'm open to suggestions of examples as well as edits to the words. My experience with tires is rather limited.

Nominate Kenda TrakMaster IIs for . . . I ain't sure! :)

DOT, but knobby as all get-out. Surprisingly versatile; quite rideable on pavement, but . . . I'd give'em TWO black diamonds; at least one-and-a-half!

Check out tread picture.

All those knobbies with huge rectangular gaps… gotta be double-diamond right? Barely for the road if at all? I've edited my earlier post and added it to the list!

Good job, and appropriately classified by you IMHO, samuel!

As mentioned: The TrakMaster IIs are versatile; better on pavement than one might think!

Surprising, to be sure, but . . . validated to me, from my experience, at least.

And . . . they are DOT (Department of Transportation) street-worthy! :)

So these are great for dirt, OK for street, noisy on the highway, and perhaps a lil' squirrelly in a crosswind (am I remembering that correctly)? Eventually I feel like I'm going to end up with >1 pair of tires… perhaps worth a look for camping days.

Damocles 01-13-2019 03:58 AM

Didn't notice excessive noise on the highway, nor particular difficulty in a crosswind. My riding style: I don't channel John Surtees on the pavement, myself, or race sport bikes in the twisties. Surely, the laws of physics apply to these tires, as they do to all knobbies. Certainly, the tread wears faster on the slab than does a less aggressive tread.

I have two sets of wheels for my KLR650; one fitted with 50/50 Kenda K270s; the other with TrakMaster IIs. I expected great road compromise with the knobbies; was surprised by their control and stability on asphalt and concrete.

No, the GP racers don't use knobbies; I'd just say I can ride TrakMaster IIs on the Interstate, within conservative reason, without becoming in my view a particular hazard and menace to safety; YMMV!

samuel 01-13-2019 03:01 PM

Ah, I must have been remembering something else… difficult to keep track of the various snippets as I scan past/present forums. TrakMaster IIs: impression updated.

Alright, I'm off for the second wave of carb tweaks. Wish me luck…
