Too new to the 911 game to give advice on sizes, but for tires I can help. I’m assuming this is for DE? How much experience do you have? 888’s should last a bit longer then nt01’s, both are great, nt01’s have more grip, but that may not be a good thing if you’re newer to DE.

245/305 Nitto NT01’s are the way to go. Have them on my car for DE’s. Great setup. I also run 18’s 9” front 12” rear. You will want to run them at 32 F 34R HOT so first run you are going ou 23/24 psi cold.

thanks for the feedback I am new to DE’s so want to make sure I don’t go way overboard, but i figured this was a good start for tires.

You will find that most street tires will get torn up very quickly with DE use. The street tires provide good feedback and training when you start out doing DE’s. but get expensive. As you get more seat time having a dedicated set of wheels/tires is a good choice. My personal opinion is the Nitto is a great tire and preferred over the R888 at least here in the west, very consistent and you can run them to the cords.
