No way is 80psi over-inflated either. I run around 100psi.. bit more when racing.. and most tyres will handle a lot more before self-destruction.
clefty: Do you fit the tyres with tools (tyre levers, screwdriver, angle grinder) or with your hands/fingers only?[/quote]
when i first put the contis on this weekend there was a lot of levering involved with a couple of tyre levers, however when i changed the rear one the first time (after the initial tube popped whilst pumping it - which now makes me a bit jumpy round track pumps as well - but that was definitely a mixture of bad installation, hurting fingers and tiredness) i took out one side of the tyre bead to remove/fit the new tube then got as much in with my fingers until i had to use tryre levers for the last 5 inches of tyre or so.
I think maybe i just gotta be less brutal, i thought i was uber careful seating the tube round the rim with my fingers last time, pumped it up slightly them re checked it to make sure it was seated, then pumped it up again to 80psi, I rode about 30 miles on that back tyre before i got back home, topped it up a little - still not over 90psi..which is when it went pop -half an hour later in my hallway..
maybe its just the tube in general that hates me..i can't win - when I take the Northern line it screws up, now when i try to cycle the tube fails again! Is this TFL getting their own back for them not getting my travelcard money anymore?
