Trials tire???

Anyone use one on the WR²???? Gonna Mount a Pirelli MT 43 Tomorrow for the Northwest Singletrack...Anyone try one yet..?

I'll be interested to know how it goes (rolling radius, clearance etc). I need to fit one for my 'bit of fun' hare&hounds we're doing in a few weeks.

Tire fits, It is Taller than the 606...Super grippy and really smooth on the street. Pipe Wrap works well. Smokes a bit when you install it but no more melted pants and forest fires...

Looks good but I would be careful going down the highway as the tire is probably not rated for any kind of speed. Should check the speed rating on the tire...

Its DOT legal and rated to the mid 80's mph.

Says they're rated to 93mph... nothing on DOT rating but I've heard/seen from various places they are. RAMZ over on ADV uses them, and its something I'm considering for me next off-road tire when I wear out the Kenda's and the mostly fresh D606 I've got sitting here.

For Sure DOT...Rim Locks...and I really dont ride over 65-70....Lotta singletrack in Washington...

Waddya mean, on ADV; I'm here too

Here's a pair of DOT-rated trials-type tyres mounted on my WRR (heading over Tincup Pass on Sat afternoon):


Oops, can't see the tyres. Try this one:


The reason I say 'trials-type' is that the DOT-rated tyres are not really actual trials tyres. They just look like trials tyres. The rubber is quite a bit harder on the DOT-rated tyres and the rear tyres are bias ply, unlike real trials tires, which are radial. But for the sake of brevity, I'll just call 'em trials tyres like everyone else. (scuse me - trials tires).

Here is what is on the MT43:
Rear trials tire

That "64P" is the speed and load rating. I'll find my speed rating chart and post it up ASAP (see below), but as I recall, they're rated in the 80-90 MPH range.

On my ride Saturday, I was hitting 50 MPH on the paved road near the Taylor Park Trading Post - runs just fine. I can't begin to approach that with my CRF230F with an IRC TR-011 'real' trials tire on it. The CRF wiggles badly at anything over 40.

Here's one speed/load rating chart:

The speed section only:
Speed Rating Chart

Motorcycle Speed Ratings

Maximum Design/Test Speed
J Type 62 100
N Type 87 140
P Type 94 150
S Type 112 180
H Type 130 210
V Type 149 240
Z Type 149+ 240+

Wow - P is rated 94 MPH. That's fast enough for me.

I'd like to know how they do in serious off-road (as in deep mud). The tread design looks tight for expelling mud, and the Dunlop "trials universal" tires that came with early Yamaha enduro models were not good in mud. Of course we know that you can't go by looks, or else the Trail Wings would actually be good in mud.
