250-500cc Trials tire, no adjustment?

Been running the Dunlop with the same chain length as the knobbies with no problems. Since I put the Perreli on I had to add a link which in turn moved the wheel back to the last notch on the swingarm. I'm assuming eveyone else is in the same boat, no issue's?

Running the Pirelli on my 310 I've ended up running it with the axle all the way back - and prefer it there. I had to ad 1 click of compression to the front because more weight up there and re-adjust the sag in the back. The Pirelli gets such good bite in all conditions I was having some problems with too much traction at the beginning of acceleration out of corners which would pick the front up unless I was WAY forward with the bike leaned WAY over - much more balanced now.

Traction is good, no complaint there. Problem is if any tension/adjustment is needed on the chain there isn't any?

With the MT43 I had to use a longer chain and move the axle all the way back. The flat profile of a trials tire will grow taller at high speed so you need more clearance than a knobby.

Tell me, I live and ride in eastern mountain country. WR250 W/300 kit. Steep snotty down hills and such. Make me understand how a trials tire will do any better or as good as a full knobby. I am interested and would like two try one out, although when I was a kid and would get an enduro bike, DT, SL and so on the first thing to go after the lights was the trials tire for a knobby. Just wondering?

Trials tires shine in wet rocks and roots. They are not so hot in deep mud or snow or if you like to brake slide in corners.

I have run the pirelli mt43 on my wr300 for a few months now. It rubbed slightly on one side of the mud flap because the mud flap had a little bend in it. No chain adjustments. I ride in rocks, roots all kind of stuff. The deep greasy mud is a problem sometimes but overall if you keep the tire pressure low the traction is pretty good. The tire holds up pretty well. I'm curious to see how other trials tires work.

A trials tire these days is nothing like a trials/universal they used to put on bikes in the seventies - do suggest you try it. Very cheap mod., for a huge change in performance. Traction is usually the issue, and a new trials tire will give you double the traction in most cases, be way more cushy to ride, and they last like crazy. Might add an extra rim lock 'though as I ripped out two valve stems this season due to the extra grip.

thanks for the reply, I might try one but probably not until next summer. winter season is almost upon us!
