i have a set of GP400 & GP400S continental tyres and on both there are a pair of dimples in the surface of the rubber - are these meant to wear indicators or are they both from dodgy batches?

    Wear indicators
  • Thanks, presumably then when the rest of the rubber wears down to the base of the dimples they're shot, right?

    They'll be shot long before that happens :lol:

    give it a few miles and you'll be more worried about the sidewalls pealing apart. I did always think though that having a thinner part of tyre for a wear indicator was a silly idea. I know the chances of either of those two bits running over something sharpish is small, but you know its going to happen in the dark and wet....
  • actually i the sidewalls are going first (after about 2000 miles) so i may change them this weekend

    :D Hopefully not! But its the reason I stopped using them, they seemed to start fraying really early.

    I think Continental tyres tend to have a flimsy carcass and soft and thin rubber, and the models I have tried wore quickly and were prone to cuts and punctures

    In the last 12 months, I've had GP4000 25c with reflective sidewalls, GP4000-S (little used as on best bike), GP4 Season.
    They've all been absolutely fine, and I've never had a puncture with any of them even though I ride on pretty poor quality roads, though to be fair the most miles on any of them was 2,000 on the GP4000 - and they're all still in service.

    People either love or hate Contis. My only poor quality pair were some cheap ones that I had on my 27x1 1/4" station hack - they blew off the rim!
