Ever thought about using a Trials Tyre

[Anonymous]

They look funny. You get lots of strange comments, but they are definitely worth trying.

I have used a trials tyre on the back of my bike for a couple of years now and probably won’t go back to knobbies (unless off course someone gives me one )

The grip is awesome in 95% of terrain that most of us like to ride in. Probably the only terrain where a knobby excels over the trials tyre is deep soft muddy conditions. Due to the contact patch of the trials tyre, it is less harmful to the environment as it doesn’t rip up the ground like a knobby does. I have heard that there also reduce global warming, but this could just be bullshit.

I run my Dunlop D803 tyre with metzeler ulta heavy duty tubes. One of the main reasons is that I normally run 8-10 psi, which makes you more vulnerable to pinch flats.

My next tyre will be the Pirelli MT43 as by all accounts this seems to be a better tyre as far as wear and more suited to trail riding.

Next time you are due for a rear tyre, have a think about the option of a trials tyre. Here is an article about them.

Nice thought Champ but I have a few questions I am not meaning to shoot it down and maybe I dont understand so here goes maybe we can straighten me out.

1/ Dont you need a rekluse clutch to reduce or stop wheel spin, or the tyre would have all the knobs ripped of, I ask this because the tyre is super soft and wheel spin would destroy it? I did a short circuit race years ago after the race I went for a ride with a mate and destroyed the tyre in about 30kms, rekluse make the difference?

2/ 8 to 10 psi even with heavy duty tubes would still be a flat tyre waiting to happen wouldnt it, I see flats with ultra heavy duty tubes at 14 to 16 psi all the time and they have stronger ply side walls (normal tyres that is)than soft side wall trails tyres, and dented rims, ask chicken about dented rims, that worrys me I run mousse’s to stop that as tubes always end up with dents for me

Nigel,sorry mate I tend to agree with TB,my thoughts are trials tyres for trials bikes, knobby tyres for knobs oh eeerr shite you know what I mean:laugh: ill stick to my retreads!!

Fark it, I just spent 20 mins typing a reply addressing the issues raised and it timed out!!!

Mods, you gotta fix that problem up as it is a REAL pain in the arse. I now need to get remotivated to type it all over again. Maybe tomorrow.

Hey Ollie the local retread dude here is giving me one to try, so I will be running one for the first time on the XR600 this weekend. He is supplying me with a 120/90 which is what size I normally run.
How long have you been running them.

Nigel, If that happens again just hit your back button and then submit it again.
But to be safe, I always type long responses and posts into a word.doc then copy and paste it into the reply box.
Something else that will work is if you have a long post, copy it before submitting so you effectively save it in case shit goes wrong.

gyday Mick,ive been using them for about 7 years all up,originally started with the recross and liked them,and in the last 3 years have been a dealer for MX retreads.I’ll have a new front this weekend but will change the rear after the 3 days of riding this weekend.Mark Bearman (MX retreads guru)has told me that the tyre sizes all come out at 110/90 when they get re-capped,works fine on the Yami 4fitty.

if anybody wants to try a retread this weekend or on future rides give me a PM and I will bring some along only $70 each to old bulls (normally $80ea or $150 for 2)

cheers Ollie

1)To my mind, wheelspin can be caused by lack of grip or too much throttle. The trials tyre gives that extra amount of grip, and reduces wheelspin. It’s like a car spinning the wheel in the wet. You don’t just keep it hammered, you back off the power until you achieve traction again. It’s not uncommon to get over 1200km from a trials tyre as long as you don’t drive on tarmac, as the tyre doesn’t needlessly spin anywhere near as much as a knobby. A Rekluse clutch definitely also assists in reducing wheelspin, particulary when start off on a slippery surface or a hillside.

2)If you are getting flats running those sorts of pressures, then this tyre is not for you. They are not designed for high speed running and hitting square edges at high speed. The extra grip of the trials tyre allows the use of less momentum to overcome an obstacle on the trail, hence saving smashing the rim. You could always inflate the trials tyre to higher pressures but this simply defeats the purpose of how the tyre is designed to work through the deformation of the sidewall.

I am not out to convert anyone to the dark side (yeah been watching all the Starwars movies on TV latel) more a case of making one think of other option. It’s like homosexuality. Don’t knock it until you try it.

Just kidding about the above statement….not that there is anything wrong with that.

Firstly I am all for change and improvement and I didnt want my questions to sound like I was bagging you or your ideas or anyones for that matter

I drag alot of back brake to steer when I ride and steer it with the rear wheel on exiting corners and this gives tyres a fair bit of grief

I look forward to see this and as before stated your rekulse clutch in action

Again I am not bagging, just would like to see it work

Thats enough of the poofy talk boys next they will be making a movie about gay trailbike riders (brokeback hillclimb) :S
