Only £20 for a tyre, what kinda cheapskate are you?
I used Conti’s for years & they are great for the price IMO, flawed (predicatable slides for the most part) but decent value.
Changed to slightly more expensive tyres and have found them to be better & am able to progress my riding with confidence due to them.
What’s the best bargain is ppl completely hating of a set of tyres after a couple of rides, I’ve had a couple of sets rejected by ppl at great prices that worked fine for me, the g/f or m8’s (Conti MK’s, Bonty ASX, Hutchinson Bulldog’s). Then other times you see ppl selling complete rubbish for almost full price, swings and round-abouts, of the STW classifieds
