Another vote for Continental Ultra Gatorskins.  I'm 6' 3", 210 and ride in San Diego on hot roads with lots of debris.  I've used some other pretty good road tires--Armadillos and Specialized--but have had the best luck with Continental Ultra Gatorskins.  Xlt flat resistence, roll smooth and corner well, and pretty beefy sidewalls.  I ride 700 x 23s.

I ride year round and can go 6 months/2,000 miles without a flat.  You're going to get your occasional nail, staple, or deep glass slash, but I hate to change tires on the road and these suckers keep me on the bike more than any tire I've ridden.

One complaint you will hear about Ultras, they are a bitch to mount, very tight over the rim, especially the wire version.  (You might just have your LBS mount them if this is a problem for you.)  The non-wire, folding version is $10 more and approx. 50 grams lighter per tire, so I've gone to those because they both are a bit easier to mount and also ostensibly faster due to weight.  When you can ride a tire 8-12+ months, the price really isn't much of a factor.  Pay for quality, get it.

I usually buy Ultras at Performance Bicycles when they have their sales, usually ten bucks off, around $40-45/tire.

The suggestion above about rotating the rear tire to the front after a certain amount of wear is xlt.  Back tire wears faster so smart move to milk the full life out of a pair.

Good riding!

Continental Grand Prix 4000 tires - 600 miles later and only on flat on the front tire.  Love the tires, though.  I may take a look at the Continental Gatorskins for my next set.

I used Lithions and split the rear tire on day #2. Trashed them and got a set of Maxxis Re-fuse. Great price and no flats, knock on wood. I have put 1,000 miles on them so far. I run over metal and other debris and nothing seems to puncture them. Not the fastest tires in the world but for the price/performance ratio, you cant go wrong. I run them at 115 - 117 psi.

GOOD LUCK!
