I've been riding Continental Grand Prix tires for years on my road bikes. Last time I needed a tire I cheaped out and got a Continental Sport 1000, on sale for $12. I couldn't resist since the Grand Prix is about $45. I've ridden the Sport 1000 on the rear for 2,000 miles and honestly can't feel a difference from the Grand Prix (which I still have on the front).
As I mentioned in another post, it failed today with a sidewall slash after I rode through some finely ground glass. I was surprised such small pieces of glass could have produced such a large cut. It's close to half an inch long (after reinflating the tube), perpendicular to the tire tangent (meaning radiating out along the line of a spoke). It starts in the middle of the sidwall and extends up into the tread.
I'm wondering if the cheaper tire is responsible. I've never had a sidewall problem on the Grand Prixes, and I've gone through 3 or 4 of them, getting about 3,000 miles on each on the rear.
Is the cheaper Conti tire more susceptible to sidewall cuts?

Thanks, Michael
if I'm not mistaken the more expensive tire has an additional ply and more rated strength than the Sport. I ride on tires that have Aramid fibers in them: Vittoria Randonneur. I've not had any problems with them so far. The only gripe I have about them is the cost: $30 each.

The sidewall of the cheaper tire is probably thicker than the GP. Use a cheap tire. All will work just about the same. Durability, long life is the thing you should be after. Particularly for just use guys that ride around.

I never have understood why people JRA ride the lightweight racing tires... Seems like a complete waste of money to me.
Mike Riding Michelin Prestige tires and lovin it!

I can only go on my personal experience. I've gone 10,000 miles on Specialized Armadillos and 10,000 miles on Conti Grand Prixes with no problems ever, but got a slashed sidewall on my first cheapo Sport 1000.
Maybe just coincidence, but I don't mind spending the extra $25 per year on superstition.

Your $25 are not going towards superstition. I've owned three pairs of Sport 1000's and half of them have developed tears from general use. None of them have more than 2000 miles. But, for the price, I'm very happy with their performance.

Well I'm jealous. I have the opposite problem. Seems like whenever I spring for an expensive tire, it gets end-of- lifed by a glass cut long before I have the pleasure of wearing it out. The cheap ones, however, last forever and I get sick and tired of them and swap them out while they still have miles left, just for a change. That is exactly what happened the one time I tried Conti Sport 1000s. I did not think that they rode as nice as Ultra 2000s, though.
I think that your experience was atypical and that you should continue to buy Sport 1000s -- but for $9.99 on sale.

That's because the expensive tires you got were Conti's.
