Run-Flat Tire Replacement Cost: 225/45R18 U.S. Price Check

For a concrete U.S. comparison, Tire Rack lists a Bridgestone Turanza EL450 run-flat in 225/45R18 at $317.93 per tire, or $1,271.72 for four. Tire Rack’s listing identifies it as a 91W run-flat and says the wheel is not included. Discount Tire’s listing for a Pirelli Cinturato P7 225/45R18 run-flat showed $314 per tire and a four-tire cart of $1,256, plus free air checks, flat repair, and rotation. Its product page is a live seller listing, so availability and store can change.

The four-tire difference is $1,271.72 − $1,256 = $15.72 before installation, taxes, disposal, or road-hazard choices. The near match does not make the tires interchangeable: brand, model, OE marking, load index, speed rating, and vehicle fitment still need to match.

Tire-only prices

Seller and product	Size and rating shown	Tire-only price
Tire Rack Bridgestone Turanza EL450 RFT	225/45R18, 91W	$317.93 each; $1,271.72/set of four
Discount Tire Pirelli Cinturato P7	225/45R18, 95Y XL	$314 each; $1,256/set of four

Both pages are product prices, not a complete installed quote. Ask the shop to add mounting, balancing, TPMS valve or sensor service, disposal, taxes, alignment only if measurements require it, and road-hazard coverage. A tire seller’s free rotation or flat repair also does not equal a new-tire installation.

Confirm the car’s run-flat requirement

Give the provider the VIN and tire-placard size. Ask whether the vehicle requires an OE-marked run-flat and whether front/rear sizes are staggered. Tire Rack’s listing warns that run-flats are recommended only for vehicles originally equipped with self-supporting run-flats and a TPMS system. Do not substitute a conventional tire solely because its sticker price is lower.

The displayed listings support a current 225/45R18 shopping reference, not every run-flat size or a national average. Save the cart and product code, request an installed total, and refresh both pages before ordering because prices, inventory, and promotions are live.
