Here's how they worked: Loam About the worst place for a trials tire is where the traction is the best, so of course loam is far from home for these puppies. Here you are used to getting that full-on bite and dig of a true knobby, rewarding you with clawing action, and a trials tire is much more inclined to spin up with this much juice.
Flats You get pinch flats more readily on a trials tire due to the softer sidewalls, and it is a bit easier for sticks to stab through the softer rubber between the knobs. If you smack into rocks and nail square-edged bumps hard, you will pay in flat tires and in rim dings. Mud They might look like they'd pack up and not grip, but the knob spacing is so close that they do not let the mud reduce the bite of the tire too much.
And they seem to dig in deeper in soft stuff and float smoother on the slightly cakey mud than a normal knob. They don't work when spinning, and they are even worse when in a full-lock skid. Great for Trails One thing we've seen is that trials tires are great for trails. They don't displace too much dirt and since they hook up better in technical areas the parts of trails that get beat up the worst , they help preserve soil conditions.
And if you wonder how enemies of trail riders are going to go after us as soon as we conquer sound, I have one word for you: erosion. I am on my 2nd 18" Shinko and I've come to the conclusion that it's my last.
Too bad, because it performs great. It is very sticky and climbs anything. When I rode it at lower PSI like other trials tires, I smacked a root and the rim sliced two 1" cuts on both sides of the side wall. On my current one, I have a few heavy gashes, just not all the way through the sidewalls from glancing blows off sharp rocks. One reason I got the Pirelli is they are said to be a little tougher than the Dunlop A trade off for performance.
For 19" wheels , looks like there are two choices. We need a Vee Rubber ride report and an 18" trials tire shoot out. On several big block KTMs I've tried and liked the trials tyre, but only the Pirelli could stand up to the duty of the or cc motored bike. Only the Pirelli didn't shed most of its knobs after one long weekend of riding. I'm sure it sucks on a trials bike, but for a big block play day or racing for that matter I also disagree with some of the stuff said in this thread and in that dirtrider review.
The tires work great in nearly all conditions, and they outlast a knobby by a long margin. I see no disadvantage to the tires for woods riding period. About the only time I would say I'd wish I had a knobby on, would be if I were blazing new trails through a area with heavy pineneedle coverage on the ground, that is probably the one area the tire don't do good in.
So far I would say the tire to beat is the Dunlop For the money it is the best buy. I have used the michelin and felt it was a slightly better tire and it seemed to last much longer than the dunlop, but it is a much more expensive tire. I have used a shinko and it sucked I have used the IRC and it was okay, seemed to not have as much raw grip as the dunlop. Used the pirelli , and it doesn't have nearly the grip as the dunlop, it is so much less traction that I don't think it is worth using over a knobby.
I recently bought a few Vee Rubber tires and plan to use those I don't have much time on them, just two rides on my KX but so far from what Ive seen it seems to be about the same traction and wear as the dunlop. I will say that when I started riding trials tires I was slower than I am now. I was maybe a solid mid pack C rider. Back then, a Dunlop would last me for months. Now that I am on the edge of a promotion to the A class, I am finding that I am wearing these tires out much faster.
But they are still outlasting a knobby by more than double the hours and miles. I have tried going back and riding knobby's to see if I can be faster on one and the biggest negative thing I experience with a knobby is the harsher ride of the harder tire and I don't like the unpredictable behavior over exposed roots in the trail.
With the trials tire the back end pretty much follows the front end, over roots, rocks, whatever. Very stable and predictable. With a knobby that isn't the case.
I just killed my second Shinko in less than a year. Another cut sidewall. I've decided to go back to knobbies. The trials tire hooked up great for rocky singletrack and gnarly rocky wash type stuff. In addition to techy single track I like to get after it in the washes, where there's always a chance of slamming something hiding in the sand or a random helmet sized rock jumping out from under the bike in front of you. Forget about cornering, there's no traction out on the side of the tire.
Lean it a bit to far and you're sliding. WFO in a rocky wash will just burn the knobs right down to a nub. I can see a place for these tires, and maybe tire companies will make a tougher sidewall that won't cut as easy.
Maybe I just need another bike. I can now run it at 10 p. If you used a cheap shinko and you don't like trials tires, don't blame it on trials tires Thanks for the review by someone who has actually used all of the brands.
My previous "trials tire experience" was back in the 70's with the old "Death Wing" tires. That soured me to even trying a trials tire for a long time. A friend has the shinko 19 on his kxf, he didn't think much of it this summer when everything was dry. But now the rocks roots logs are slick he's liking it. ALL tires are conditions specific, hard soft intermediate paddle trials etc. Trying to say one is better than the other is pointless IMHO.
I installed the 18" Vee Rubber trials tire on my enduro bike last year for the DurtyDabbers. I've never owned a trials tire before this. I was told it's common to run low pressure 9psi and to make sure you have two rim.
The moment I started riding, I couldn't keep the bike straight and two guys following me told me I had a flat. I stopped and. It still felt like a flat tire, but not as bad as before. Later on, the guy. Once we got into some of the the snotty terrain, I could fully appreciate the tire. It still felt like a flat tire, but the traction on. It like I was cheating. It felt like I could pick any line in the rocks and it was guaranteed.
I still. The most surprising characteristic was this tire worked well even in regular soil and muddy conditions! I though for sure this tire. After numerous rock runs on my I want to buy another trials tire for my second enduro bike. As great as the Vee trials tire is, I'm wondering if there's better out.
Some people have told me their trials tire doesn't feel like it's gone flat. Maybe it's the nature of trials competition that. Check to see if your tire is seated on the rim.
