The current formula pro x guard tyre on there at present has nearly 4400km on them and the centre section of file thread is worn but the tyre looks like half way through it life according the wear dimple. the front 28mm RBCC tyre has 11000km on it and no wear to the file thread. These tyres can do huge miles. On a race bike with less rear load mileage would be higher. The roadlites i use on my race bike (lower Crr than the RBCC but less grip) have around 2000km on them and there is no wear not even rounding off. The formula lights I also use on the race bike have 3000km and again they almost pristine.
This is IRC's party trick. I can cope with a tight fit because once on it is one for a long time. I would not worry about a puncture. Over the life of the tyre for me it will be patched and stuffed with worms (flint everywhere and it slices through everything then add gravel road and farm track riding) and they solider on. I leave my tyres fitted untill they are bulging or worn which ever comes first.
The sannio will get some maxxis pardones when I get back from hongkong as I want to see how they fair on wet suffolk lanes.
Sanjay, the IRC's i use mostly are a tigher fit than most tubeless tyres but do not snap in place. The op sound as the bead locks is a schwalbe thing. the mavic tyres dont do that either. When a tyre pops it is because the bead is not sliding into the bead hook smoothly it is snapping into place. not all tubeless tyre do this.
To test the bead lock deflate the tyre and see if it stay locked in place with no sealant in place. If good thumb pressure has to be applied then you can ride with a flat. if it falls away with light pressure or with no thumb force then you cant ride with a flat and may get burping riding a low pressures after a puncture. hense why a good fit is important to me. I dont want to stop even to top up with air mainly because I can and do forget my pump.
thanks bm0p700f .... I'm well pleased with the IRC Formula Pro RBCC so far, and when I need to change them,(most probably in March), I will order the IRC Roadlite Tubeless ....
is there any info on the rolling resistance of the IRC tyres?
