Anti-Puncture Tyres At-a-glance

I'm just about to replace my Continental Grand Prix 4000 tyres. They've been in use for over a year and have about 4,500 miles on them.

I'm only replacing them out of caution as they've not punctured once and the outer does show a number of marks but nothing substantial. I'm a firm believer of replacing before something it fails.

I'm replacing them with the newer Continental Grand Prix 4000s. Hopefully they'll prove as good as the ones I'm taking off.

Hi Velocio,

Heard you on Resonance, was a good show. So how are the 4000s's faring? Are they as good or better? Thinkinhg of trying one out on the back.

Cheers.
