I was wondering what everyone was doing for rear tyres. I have been told the tube type michelin has been discontinued, is this true or not. I have a tubeless 36 spoke morad rim but am resisting using it as I would like to keep the bike looking period correct. I can get IRC tube type rears, but was concerned they might not stay on the rim, the bike is a bultaco with akront rims.

Cheers Greg

I have no trouble with IRC tube type staying on the rim with my M49 Bultaco even when I run them down to 4 psi.

The IRC tube type stays on nicely on the standard rim on my Cota 348 (1976 shoulderless Akront) and the standard rear rim on my M49 (1968 shouldered Akront)

I also stays on my Ty TS and I has one on a TY Mono.

I have found the the IRC tubed tyres stay on the Akront rims okay but you have to run higher pressures in them as the sidewalls are so soft. I found the older Dunlop tubeless come away from the bead and I just use tubeless Michelins which come away at 4 PSI but they will stay put using higher pressures. I gave up caring and just use Michelins as they do have the best grip and the best feel. I run the rear at 3.5 to 4 PSI and if the tyre wants to wobble around I just let it do so. I run two rim locks which helps. Graham.

Thanks for the replies and yes I have tried a Dunlop before but it kept coming off the rim at trials pressures,apparently OK on DID rims, so I guess its an IRC - can anyone confirm the whether or not the tubed michelin has been discontinued.

Thanks Greg

Tubed Mitch, not as good as tubed IRC, in my opinion.

I've used tubed and tubeless IRC on the Bultaco with akront rims for 5 years or so - always with tubes fitted. Run a 3 psi no problems ever.

 can anyone confirm the whether or not the tubed michelin has been discontinued.

Thanks Greg

 

 Here in the USA they've been gone for several years.

I've also been using IRC tubed (49,125) and tubeless (183) with no problems on my Bultacos

The IRC I used where TR11 not TR1 there is a difference. ( in price too ).

Thanks will order an IRC and give it a go

Cheers Greg

I live in France and can get tubed Michelin's no problem front and rear, from memory the last rear  one was 112 euros..  divided by 1.32 equals...... I use them and they are great, as are the IRC and another funny make a friend gets from the Uk . Howver its mostly dry here so even if they are knackered they work.
