IRC Radial Trials Tire

Comments On Sep 19, 2012:I use these tires on the rear of my KTM 300 XC. They deliver excellent traction in all conditions and long wear. I use the tubliss system and am very comfortable runnning higher speeds with this tire. I previously used the michelin tube type trials tire, which also delivered good traction. However, it was considerably more unstable at higher speeds.

Excellent

Comments On Mar 21, 2012:I go back and forth between these and the Michelins - I honestly think these are a great value for the money - soft enough for great grip and still wear quite well - I use them on enduro bikes but have used them on my trials bike (when I had one) as well.

Don't Buy if you ride faster than 40mph!

Comments On Nov 27, 2011:I bought the IRC TR-11 trials for the 2011 LA-B2V dualsport ride. On pavement, if you exceed 40mph the sidewall flex is so bad it is difficult to control the bike. On dirt roads it's a little bit better, you can get up to 45 or so before the wobble gets too bad.
However, if you never exceed 40mph, the tire is amazing! Great hook-up in all conditions, including sand washes. Climbing decomposed granite and stair steps is a breeze. Wet, loamy soil is not a problem either.
On day two, after @ 100 miles of powerline roads & jeep trails, the center row of knobs had sheared off completely - all the way around the tire. With the center row gone the tire was fairly stable up to 50-55mph on graded dirt roads and pavement.
Great tire for slower trail riding. Stick with a MT43 for dualsport use or high speed conditions.

off road trail use on KTM 300 Christini

Comments On Jan 07, 2011:Off road use in mountains and desert rocks it gives good hook up. Tire lasts longer then knobes and works when half tread is gone. It does not stop as fast as knobes.

AWESOME!

Comments On Mar 15, 2008:I ride rocks, lots of rocks. Rock ledges, loose rocks, big rocks, little rocks. And all these rocks have mud and water somewhere between them.
This tire is like cheating. Run 12lbs air and you will have to get used to the traction, you WILL kill the motor learning the traction.
I got 1200 miles on my first one, 1100 on my second and now have 700 on my third. I'll never buy a knobby tire again.

Great traction

Comments On Mar 13, 2008:This was my first trials tire- and I was impressed. Traction was great, wear was phenomenal (I got 1500 hard off-road miles before I cut the side wall; normal knobbies give me around 700 miles). The price has gone up a lot since I purchased mine ($72 irc) so I will probably try the Dunlop trials tire next. Oh yeah- I might recommend the tube version because I could never get it to seat. & bring a repair kit- flat = you're NOT moving.
