Continental tire has 7,080 miles and counting

This Continental Grand Prix 4000 S has 7,080 miles, and counting.

On March 20, 2017, I installed two new Continental Grand Prix 4000 S II 700c Road tires on my Ritchey, and they’re still going strong.

There’s only a tiny spot with sidewall fraying. That’s a sure sign that this tire’s days are numbered. I’ll only tempt fate so much to save a buck.

The tire has some flattening from wear, but I don’t think it’s all that bad. I’ve seen worse.

I’ve only had one flat. An increase in flats is another sign a tire is worn out.

I ride three other bikes, but those miles were omitted in my calculation.

My last tire with a record for miles was a Continental Gatorskin 700×28. It lasted 5,400 miles before I chucked it.

The Continental Grand Prix only cost $35, way less than the $52 I paid for the Gatorskin, back in 2014. So what gives? Why would a cheaper tire last longer?

I attribute most of it to how I’m riding these days — flat roads with little debris. In 2014 I rode a lot of dirt, mostly in the Santa Cruz Mountains, so the tires were stressed way more than they are now.

To be sure, the Continental Grand Prix 4000 S is a well made tire, one of the best. It’s still being sold, for $34-$40.

    You tires last a really long time because you don’t weigh very much! But even at 200+ I almost never get a flat–maybe every 10,000 miles. I remember how revolutionary the high pressure clinchers in the early ’80s were—but I remember flats were a pretty frequent occurrence then–maybe every 500 miles for me.

    BTW, how many miles do you estimate you have on that Ritchey frame of yours?

    Conti recently released their 5000 series tires. Hard to believe they could improve on such a good tire, but that appears to be the case.

    Jay, Ritchey has 45K miles since 2010. My Saso, built in 1987, has 150K or so.
