Rubber Meets Road: Continental Grand Prix 4 Season Review

Since moving to Tucson durable tires have become a must for me; there's nothing I hate more than a flat during a good ride or a double flat leading to a long walk. My trusty Ultra-Sports had stood up to the Flagstaff winter, but were no match for the myriad of debris that lives on the roads of Tucson.
Continental sent us some nice Grand Prix 4 Season tires to test, so I pulled off my Gatorskins to give them a try. I was worried about switching to Four Seasons over the nearly indestructible Gatorskins, but was interested in a tire that is billed as a faster training option. They mounted easily enough and I got off to a good-start on them.

The first concern was that the test tire lacked the triple layer Poly-X-Breaker of the Gatorskin, but the 4 Season is actually a more robust and durable offering, with a double layer Vectran Belt and a Dura-Skin wrap over the sidewalls. The puncture resistance of these tires was phenomenal, and I found myself really trying to test them. I rode gravel, loose wood bridges, through some good size piles of glass, and of course plenty of small bits of metal. In 1,500 miles of riding I never had a puncture. I had one flat in the entirety of my time on the tires, when one of my tubes blew in the furnace like June weather. I normally replace my tires every 2,000 miles or when they wear flat, but after 1500 miles they still have visible mold lines. A long wearing tire can often let down on speed and handling, and these tires needed an appropriate test to dispell that dogma.

Luckily Tucson has some great race-pace group rides, like the infamous Shootout, to put tires to the test. I expected to suffer a little bit more because of rotating weight and more rolling resistance, but these tires upped the ante again. While they weigh in at 242 grams for a 700x23, one gram more than the Ultra Gatorskin, the real difference comes in rolling resistance. By no means do they roll as well as a Black-Chili Grand Prix 4000; however, there is a palpable increase in speed versus a Gatorskin. I was easily able to power up and roll along in the front group without a noticeable amount of drag unlike my normal training tires. The cornering and grip was also phenomenal for an all season tire; most tires in the same class are notoriously gummy and weak in corners. They stuck in the corners and descents almost as well as race tires, and the little bit of tread made them acceptable on a few dirt-road excursions

On the whole, the tires met and surpassed my expectations. The only flaw for me was that the ride of 700x23s was a little harsh, but 700x25 tires are available, so it's not a drawback at all. A platform with exceptional puncture resistance and rolling performance, that wears well is a rarity and a pleasure. I'll definitely be riding them as my training tire in the future, and as race tires in a pinch
