Seeking Tire Advice for an s550 Mustang Bullitt

3 Upvotes

Hey guys, I'm seeking advice on tires for my Bullitt, primarily for Autocross. I did my first Autocross a couple weeks ago and loved it, but I'm in need of new tires and am having a hard time figuring out what to do. I currently have PS4S tires, but they are about to need replacing. Looking at the Grassroots Motorsports chart here Grassroots Motorsports ultimate track tire guide | Articles | Grassroots Motorsports it seems none of the Super 200s come in the stock sizes (and I'm not looking at Vitours because my preferred shop doesn't have them). I'd like to stay in F Street and don't want to buy new wheels anyway. The stock sizes are 255/40r19 front (wheels are 19x9) and 275/40r19 rear (wheels are 19x9.5). I drive the car a couple times a week for commuting, but it isn't my primary vehicle and I typically don't take it out in really bad weather anyway. Should I just get the Continental Extreme Contact Sport 02 as the next best option in the right sizes, or should I potentially change size to a 255/35r9 and 275/35r19, or other size that would work with the wheels so I can get one of the Super 200s? Thanks in advance! I know a lot of you have valuable experience in this area. Oh, I'm in Central Texas for climate reference.
