The familiar size on a tire sidewall is only the beginning of its identity. Two listings can share the same dimensions while differing in load capacity, speed designation, construction, original-equipment specification or seasonal purpose.

Read past the large numbers

Compare the complete service description and any additional designation, such as extra load or run-flat construction. Then check the exact model and product code. If a seller substitutes a similarly named item, ask for its full specification instead of assuming the change is cosmetic.

Start with the vehicle's requirements

Use the vehicle placard and owner's manual to establish the original requirements. Modified wheels or a different tire size require a separate fitment assessment. A larger number in one specification does not compensate for a mismatch somewhere else: load suitability, wheel compatibility and vehicle requirements need to agree.

Keep the comparison practical

When calling a tire shop, provide a clear photo of the existing tire markings and placard, along with vehicle details. If you are comparing two listings, send both links. This lets the shop explain the actual difference instead of guessing which version an advertisement means. It also reduces the chance that a low quoted price refers to a different product from the one you intended to buy.

Frequently asked questions

Is matching the size enough when replacing one tire?

No. The remaining tires, drivetrain requirements, service description and product construction also matter. Ask for a vehicle-specific comparison before selecting a replacement.
