Just got my MtR back and they tried to tell me no worries all done no charge but i kept pumping them. They were a bit reluctant to talk but i got out of them]
-It had no puncture
- They pulled the tube out and fitted a tubeless valve and coated it with sealer and it blew up with no discernable leaks when put in a tank
- the tube was not of a type that they use.
- the rim damage was nothing like what may cause a leak
I can only assume that I do know that rim had a tube when i took it in there to get the MTR fitted from a previos flat when running Toyos and they just left the tube in there. This is even more bizzare coz this rim had a flat when i went in ther to get the MTR fitted
I really wasnt expecting much of an answer and i didnt get one except it seems the MTR probably was not at fault
BTW the tube had a 30cm tear in it except it didnt look like a tear just like a knife had cut it but not along a seam

Davoe.

Was the new tyre a tubeless or tube type?
There is a difference.
Tubes should not really be fitted to tubeless tyres.
Can cause the tube to fold & pinch just like the tear you described.
No expert, just worked as a tyre fitter 30 years ago. (done a lot of jobs!)

Thiswas a follow up to a post I made of the same name I think it is on page 2 now. They aretubeless tyres with about 500km on them the one that went flat had a tube in it. The Boss at the tyre store was at a loss to explain why a tube was fitted with a brand new tyre the other 3 were fitted tubeless

Davoe, Further to the question was it a tubeless type trye did it have any stickers inside it ? I had some BFG's, tubeless type, incorrectly fitted with tubes and the rubbing of the tube on the edge of the plastic sticker cut through the tube to about 3/4 of this thickness and naturally the air got out!
Hard to explain how 3 got fitted without and one with though.

Davoe, have you ever actually seen the damage that you sugest say can be caused by fitting a tube to a tubeless tyre ?

I have always used tubes in tubeless tyres so that I can run very low pressures and if I break a bead I can just pump up the tube to get home.

I have never had or heard of anyone actually ever having the trouble you sugest. I have however heard lots of people say the same as you - that it should not be done !

Ken i dont know if it had stickers inside
Kiwi. I am not saying it is that much of a bad thing but a fairly pontless thing especially considering a ran 5psi on the beach my last trip to clear a difficult cutting and the only tyre i ran off the rim was the one with a tube and once again this trip the tyre with the drama was the one with the tube. there was no indication of any problem with the setup except the pointless tube that was fitted - failed
Tubes are for split rims in conjunction with crossply tryres not radials on one peice rims

The only sticker I noticed on it was on the bead near the valve. There were no stickers on the inner tube and I didnt notice any inside the tyre.

Bloody lucky the beads held and the air only escaped thru the valve hole and didnt get blown out, especially on a dirt road could have been nasty. Good to hear you got it sorted and were not out of pocket.
Bloody apprentices.
I'm still mystified why the tube was so damn hot compared to the rest of the tyre.

Looks like the MT/Rs still hold their name.
