an update on my 2017 IRC Formula Pro RBCC tubeless ....
so far, I have used them for 1,177.5km .... one puncture on the front that self sealed ... these tyres still look brand new. They grip like superglue, and roll fast (I have not seen any rolling resistance data yet, but I'd rate them better than Conti GP4000 SII) ... I will try the IRC Roadlight Tubeless next (these are even faster rolling)
I asked the chap from Cycle Clinic about what sort of mileage I can expect from the IRC Formula Pro RBCC and this was his reply:
quote:
dim, on my commutor bike 9 kg with 6kg load min and 87kg of me I get 7000km from the last rear RBCC. it was bulging at that point from impact damage (ridden off road alot) but it was actually not fully worn. 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.
on a sidenote, I read that when you park your bike for long periods, you should ensure that the valves are not on the bottom of the tyres/wheels where the sealant pools (i.e. rotate the tyre so that the valve is on the top of the tyre .... I'm not sure if this is true, but I do it anyway
