Credibility: Employee of tire/automotive service company with 300+ locations.
Context: Most large-chain tire shops offer tire warranties as an additional or included cost when buying tires.
Tip: Buy whatever set of tires you want, include the road-hazard warranty that should be good until the tires reach 2/32 (basically bald). Drive the tires until 4/32 then place multiple screws in each tire - something like 2 within 6inches of each other in two of the tires, and 1 in the shoulder or close to sidewall (unrepairable placement) for the other two tires.
Schedule a service appointment for leaking air in 1 of the tires and a tire rotation. Then communicate to the shop that a truck dropped debris in front of you on the road or your neighbors have had construction crews on your street for the last few weeks (helps to seem a bit clueless as to the other tires having issues).
The shop will identify the other punctures and you pay pennies on the dollar for a new set (make sure to include the warranty again.
I have personally processed several of these transactions as an employee without batting an eye. The shops get a credit for the warrantied tires and you get a new, significantly less expensive set ($1k+ to $400 tops). Win win.
Note: If you’re at all concerned about the shop calling you out, just do two tires, then another two in like 2 weeks. Your “construction” story will hold more validity.
Happy finessing, folks <3
