With the Takeoff's I wouldn't chuck them after 3-4 runs, but I could definitely notice a difference. After about 6-7 runs I'd throw a new set on, and use the others for practice. Yet another reason i like foams better...no inserts to deal with...and no real handling difference as you use the tires (provided you don't chunk them).
