Repair or Replace a Tire: Inspect First, Then Price

A flat tire is a reason to arrange an inspection. It is not proof that you need a new tire, and no photograph can settle it. The decision is made on the inside of the tire, which means the tire has to come off the wheel before anyone honestly answers the question.

The four rules, and where they come from

The US Tire Manufacturers Association publishes repair criteria. A trained technician must inspect the tire before approving a repair.

1. Tread area only. The shoulder looks like tread and flexes like a sidewall, which is why it is excluded. Nothing in the sidewall is repairable, ever.
2. No larger than a quarter of an inch, about 6mm. A framing nail qualifies. A gash does not.
3. The tire comes off the wheel so the inner liner can be inspected. Damage that looks trivial from outside is often much worse against the liner.
4. A plug fills the hole and a patch seals the liner, usually as one combined unit. Both, together, or neither.

Rule four is the one that decides which quotes are real. A plug pushed in from outside, with the tire still on the wheel, is not a repair under that guidance. It seals the hole without anyone looking at the damage inside and it leaves the steel belts open to moisture. We will not do one, and you should not accept one. Plug against patch is the full argument and a nail in the tire is the version with the diagrams.

What turns a repairable puncture into a replacement

• It was driven on flat. Driving while deflated can cause internal damage that is not visible from outside. Tell the technician what happened.
• Repairs too close together, or overlapping an old one. Not permitted.
• The tread is nearly finished. Repairing a tire with little left buys very little. When to replace tires and the tread law where you live, because the legal floor is not the same number in every state.
• It is a run-flat. Repairable far less often and under stricter conditions. Say so when you book. EV and run-flat tires.
• Sidewall or shoulder. USTMA limits puncture repairs to the tread area.

Do not pull the nail out

While the nail is in place it partly plugs the hole and the tire often holds enough air to stay on the rim. Pulling it out in the driveway turns a slow leak into a flat and tells you nothing, because the answer is on the inside. Check the pressure against the door placard, top it up if it holds, and book.

What HopTire's repair costs

HopTire charges $169 for the first tire and $50 for each additional tire repaired in the same scheduled visit. We remove the tire, inspect the liner, and use a combined plug-and-patch repair when the injury qualifies. If a technician attends but the tire cannot be repaired, we keep $99 for the visit and inspection and refund the rest of the repair charge. We do not charge for a repair that did not happen. A selected same-day visit adds the displayed $75 fee; it does not guarantee availability. See the repair service and start a request. The complete amount appears before payment, and we confirm the visit separately.

If a safe, suitable counter repair is available to you, it may cost less than a mobile visit. Confirm that the provider will remove the tire and inspect the inside. Free flat tire repair explains that option without treating a plug-only service as equivalent.

What replacement costs instead

If the answer is replacement, the tire product is priced separately from installation. What mobile tire replacement costs explains those parts.

For new tires we supply, installation has a metro-based mobile visit charge plus a per-tire charge for one to four tires. Mounting, balancing and old-tire disposal are included; tires are priced separately. See pricing. The total appears before payment. We supply the new tires we fit; ordinary customer-supplied new-tire fitting is not offered.

Ask how many you actually need before you buy four. For AWD, the answer depends on the vehicle maker's rule, the actual tires, and their condition. One bad tire on an AWD car gives the repair, match, and replacement decision. How many tires do I need is a general starting point, not fitment approval.

What to ask whoever you call

The vehicle is parked safely. The tire lost pressure, and I did or did not drive on it, for this far. Will you take the tire off the wheel and inspect the inner liner before quoting? Is the repair a plug and a patch together? What is the inspection charge if it cannot be repaired?

Ours: if the damage turns out not to be repairable after an attended inspection, you pay $99 for that visit and inspection, not the full repair price. Replacement needs your approval.

Questions people ask

• Can a nail in the tread always be repaired? No. It must be in the tread area, under a quarter of an inch, with the tire off the wheel for an internal inspection and no overlapping previous repair. The inspection decides, not the photograph.
• Is a plug on its own good enough? Not under the US Tire Manufacturers Association guidance, which requires the injury channel and the inner liner both repaired. We do not sell plug-only repair.
• How much is a mobile puncture repair? HopTire charges $169 for the first tire and $50 for each extra tire in the same visit.
• Do I pay if it cannot be repaired? If a technician attends and inspects it, we keep $99 for the visit and inspection and refund the rest of the repair charge.
• Does a repair mean I have to buy tires from you? No. A replacement is a separate decision and needs your approval. We can quote a supplied new tire and installation after fitment review; do not assume it can be completed in the repair visit.
