why do people think this ? you just shave a new tire down to the diameter of the existing tires.

Because while this is 100% a thing and anyone who has taken a vehicle to the track knows this, Les Schwab or Discount Tire aren't doing this for you.

Yeah I'll admit I've never seen a shop I've gone to offer that as a service; the closest I've gotten is getting the shop's extended warranty on the tires, and then they'll pro-rate the remaining tires on replacement. Still had to pay labor tho.

What kind of tire shops should I look for? Smaller ones or specialty ones?

Independent tire shops without known brands and/or racing-oriented stores.
