How are the tires holding up on your bicycle?
The rear 700x32 Continental Gator Hardshell (100 psi) on my touring bike last year went 2,000 miles easy, and still works but has a definite flat spot center tread and so should be replaced. Front one, same mileage, still looks good.
Truth be told though I haven't ridden that bike hardly at all since last summer. No bike trip this summer, but around 70-100 miles a week through the school year, urban street-riding on a mountain bike.
On that bike I've been using 26"x 2.0 Schwalbe Marathon Plus Tours (70 psi).
Maybe 3,000 miles on 'em now, slight wear on the rear, none noticeable on the front. User reviews rate 'em as being a 5,000 mile tire, I'd believe 'em. Almost no flats even in the broke glass and debris places I end up riding.
Hoping to ship my bike to the UK next summer and put in another 2,000 miles over there. Dunno if I'll take the touring bike or the mountain bike to do it on yet. But whichever I take it'll be on Schwalbe M.P. Tours, I like the tire that much.
About $60 per but worth every penny.
The Gator Hardshells are lighter and being slicks, got a bit less rolling resistance, but they don't offer much traction the times you gotta bail off the asphalt onto the roadside grass and dirt. The MP Tours OTOH have a fairly aggressive tread and grip good, yet still run pretty quiet on the asphalt.
