Have a read of the following and try to make some sense of it,the Pirelli is listed in Oz as a Flat Track speedway tyre,Radial trials tyres are supposed to get great traction from having flexible sidewalls and as such should not like spinning up and sliding and in other radial trials tyres are horrible on the road with low pressures ,not nice,anyway the Pirelli has a much stiffer sidewall,is great on the road,allowed spinning and rear slides,plus great traction on big hills without ripping the ground up,they work a bit like the mini knobbys the FIM use in the 6 day only with more traction,be interested in other opinions re these tyres.

Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!
Trails tire...WHY?

...cause they are a fun way to mix things up, that's why I ride them from time to time.
I prefer the IRC TR011 tubeless tire, it's sidewall is stiffer than the tube type and handles the road much better. I had trouble with the Dunlop bead staying seated at proper 5-7PSI pressures, no problem with either IRC but prefer the tubeless tire.

So you use the tubeless tire with a tube? Any known problems with this combo?

I've been running the same set-up (HD tube in a tubeless IRC) for over 5 years now with no problems. In that time I've had exactly 1 flat tire.

Trials people used to use tubes in the rear tire, but they have gone to tubeless. Tubeless & Tube type trials tires can both be used with tubes the difference is the bead is slightly different. But some trials people still use tube type in older trials bikes.
I used the Dunlap 803 rear tubeless type with tube and except for the bead unseating while it was sitting in the garage at low pressures it worked great. Many report the bead separates from the rim on Excel rims especially Husky & a few KTMs.
I've since switched to IRC tube type and it stays seated on the rim - but does not stick quite as well as the Dunlap, which in my case is a good thing (long story).

IMO the IRC cannot be beat for pure traction plus they are kind of fun on the road, gas it around the corner and your sideways.
I just finally tried the Pirelli and am very happy with it, its works great off road (way better than a knobby) and is very stable at speed even on the road, it does not have quite the traction on the IRC but it seems like more of an all around tire with the stiff side wall.

Why use them? Because sometimes there are rocky hills like in this movie lol. In the first 15 seconds you will see me on my WR messing around riding a wheelie with my feet down. There is a longer one of me on Grave Ridge row 15-28. It was the ticket on that day.

Definately, they have such a thin sidewall they seem to put more rubber on the ground, the drawback is that weak sidewall makes then squirly at speed.

I run mine until I'm missing more than 5 center knobs, unfortunately once 1 knob goes others seem to follow quickly.
Coffee;4658 said:
They work just as well as the IRC, but they last half as long...if that.
The knobs can't wait to take their leave, it seems.

Mmm...I'd say you'd have to lose a few more knobs in order to be less thorn-resistant, but once you start losing them they disappear fast. This tire started the day's long ride with a few missing knobs. It made it back to camp many miles later with no drama and didn't lose even 1psi...

8-10psi, and that tire had about a jillion miles on it...at least.
