WeatherTech SportsCar Championship, 6 hours (P, PC, GTLM & GTD) – July 2, 2017
Continental Tire SportsCar Challenge, 2 hours (GS & ST) – July 1, 2017

Tire Sets

In the WeatherTech SportsCar Championship P teams will be allotted 15 sets of tires (including dry and wet tires), PC 12 sets, and GTD teams will receive 12 sets while there is no set limit for the Continental Tire SportsCar Challenge.
Continental Tire has designated Blacks as the dry tire to be raced at Watkins Glen. If teams move to wet tires, the P and GTD classes will move to Blacks. This is the same tire that teams are currently scheduled to run at all other tracks (Daytona is the lone exception).

Track Characteristics

Dane Cameron (No 31 Whelen Engineering Cadillac DPi): Watkins Glen is challenging as it is a great mix of super quick corners and low speed corners. It can be tricky to get the car to have a nice feel and balance in the fast corners while being strong on brakes and traction in the slow corners. They did a great job with their repave last year and the track is incredibly fast and high grip, making for some of the highest cornering speeds and g-forces we see all year. 
Colin Braun (No. 54 CORE autosport Porsche 911 GT3 R): I think Watkins Glen is a really fun race track because of the repave job and how much grip the track makes. But it also presents quite a challenge because it’s such a grippy track compared to most of the places we go to. It’s a challenge to get your car set up well. It’s a specific and unique track that requires a little bit different set-up package. Trying to find that set-up package and quick time in practice makes it a tough thing. It’s also a six hour race so a lot of teams will opt for a third driver so you need to get him some time in practice, and develop the set-up, so all those things combined make for quite a challenge.
Tire Management

Dane Cameron (No 31 Whelen Engineering Cadillac DPi): Hard to know exactly what the tire strategy will be since this will be our first time running our new Cadillac DPi at Watkins Glen but typically we take new Continental tires at every fuel stop since we have so much time waiting for fuel. There could be some opportunities for people to try and double stint the Continental's on Watkins Glen’s exceptionally smooth new surface.
Colin Braun (No. 54 CORE autosport Porsche 911 GT3 R): The easy part about Watkins Glen is the fact that it is so easy on tires. After the re-pave it’s got a lot of grip and it seems to be incredibly good wear with the Continental tires. I think the tire strategy is a little bit easier. We obviously get a few more sets because its six hours compared to the normal sprint length. It’s pretty straight forward because it is so easy on tires. I think it’s easy to double stint, and you could probably get away with triple stinting the tires to be honest.
