How long for new tyres to bed/wear in? Went out for quick spin last weekend, with 33 PSI after tyre fitted weekend before, what big mistake! I did'nt boot it since back felt slightly spongy! Got home, put it up to 40 PSI, then went out last night, it felt firmer, but thought the grip was'nt there when compared to the oems BS RE010 before. Mind you they were probably at the most grippiest when near the TWI. Hopefully the GY Eagle F1s will be brilliant when worn little! Only done 10 miles carefully at 33PSI and 15 miles at 40 PSI.
