Thanks for all the replies, the ‘blackcircles’ price has increased by over £100, so if anyone can suggest another supplier that would be great
Is that £100 per tyre? If so you must be looking at the Sprint Classic, which is about £100 more than the T-TTrac 2.
I bought 4 TTrack-2s 7 years ago for £221, now they would be about £280 from Black Circles.
