I do not understand this. Ive tried putting 70 dollar (each) tires. But its not working. I'm thinking of getting thicker tubes because at this rate I'll be buying a new tube every other day. At 8 bucks a tube it adds up. I've also tried putting tire liners in but that does nothing as well. Has anyone else had this problem. Thanks.
Agree with those who think something is fishy in Scotland. I never obsess about tubes but put some thought into the tires and sometimes the tire liners. They are literally where the rubber meets the road. Tubes should not cost $8.00. Schwalbe Marathons are pretty flat resistant as is, with tire liners you would have about the most flat protection reasonable on a Giant Defy. On my race bike I am running Continental Ultra-Sports... there isn't too much choice in the 27" size...these are cheap, light, training tires with no flat resistance whatsoever, I have ridden right through broken glass with my heart in my mouth on a few occasions, but, so far no opportunities to do field work on the tires. I've only had the bike a couple of months. Especially listen to the poster who advised you check the tire after you open it up to fix the flat. Be obsessive! Go over every square inch of tire surface, inside and out, to make sure there isn't a tiny piece glass or wire, embedded in the tire carcass.
