With bikes usually an inferior compound or tread depth just look at the code on the two sets of tyres. I have budget tyres on the Ancient Volvo a third of the price they have lasted many miles and due for replacement tread depth is the main thing for me I don't need the super grip as don't drive that way the bike its different I want the best grip and have to pay... But have noticed at jumbles and such like the tyres on sale though branded are of inferior quality..
My views only. Dont need a video to tell me.
