I ride maybe 5-10 times on my tires before they go flat
Ok, I’m frustrated. Need some advice. I don’t know much about the mechanics of my bike. I have a Trek. My husband has one too, same problem. I ride maybe 5-10 times on my tires before they go flat. Usually one 20-30 mile ride, and the rest are 10 miles, so we are talking about 120 miles on a tire. The tread still looks good, but goes flat. So I asked at the shop, they said watch your tire pressure, which I do. Yet I end up flat before long. I don’t trust my tires enough to go too far. What am I doing wrong? I never had this problem with my cheaper bikes, before I became more of a regular rider.
