Before you call for a tire quote, find the size molded into the side of your tire and the tire information label inside your driver's door. Those two details help us discuss the right options for your vehicle. This guide explains what to copy, what the markings mean, and what to ask when comparing tires at Marco's & Son Tires in Jersey City.
Read a tire size: 225/65R17
225/65R17 is an example, not a recommendation for your vehicle. Read the whole code; “17-inch tires” alone leaves out important measurements.
| Marking | Meaning |
|---|---|
| 225 | The tire's nominal section width in millimeters. |
| 65 | The aspect ratio: sidewall height is 65% of the section width. It is not a height in millimeters. |
| R | Radial construction. |
| 17 | The wheel diameter in inches that the tire is designed to fit. It is not the tire's overall diameter. |
Copy any additional markings, too, such as P, LT, XL or an original-equipment designation. They can matter when choosing a replacement. See Michelin's tire marking guide for more examples.
Keep the load index and speed rating
A number and letter may follow the size, such as 102H. The number is a load index: a code for how much weight one tire can support under specified conditions. It is not a weight in pounds. The letter is a speed rating, describing the tire's rated speed capability under specified conditions.
Two tires with the same size can have different ratings. Replacements must meet the vehicle manufacturer's requirements; do not choose by dimensions alone. A higher load index does not increase your vehicle's permitted carrying capacity. Keep the full size and rating together when requesting a quote. Michelin explains load and speed ratings in more detail.
Check the door label before ordering
The tire currently fitted is useful information, but confirm the recommended size using the vehicle's Tire and Loading Information label or owner's manual. The label is usually on the driver's door edge or pillar. Check whether front and rear specifications differ. If the installed size differs from the label, or the vehicle has aftermarket wheels or suspension changes, tell the shop before ordering. Matching one number does not confirm fitment.
Use the vehicle's pressure recommendation
The maximum pressure marked on a tire's sidewall is not your vehicle's recommended operating pressure. Follow the vehicle manufacturer's cold-pressure guidance on the door label or in the owner's manual. NHTSA describes cold tires as tires on a vehicle that has not been driven for at least three hours. Front and rear recommendations can differ. If a label is missing or your setup has changed, have the correct specification confirmed. See NHTSA's tire safety guidance.
Have these details ready for a quote
- Your vehicle's year, make, model and trim, if known.
- The complete tire size and ratings, plus any different front or rear specifications.
- How many tires you need and whether you prefer new or used options.
- Any required brand or model, your budget, and how you normally use the vehicle.
- Any wheel or suspension changes, air loss, vibration, pulling or uneven wear.
- Which shop you plan to visit and when you need the tires.
Keep a clear photo of the sidewall and door label handy so you can read the details accurately. Ask the shop to confirm stock, suitability, and the total quote, including which installation services are included. For a used tire, ask about the specific tire available, including its brand, condition and tread; an online photo alone does not establish those details.
Compare options and plan your visit
Browse tires by size, compare new tires and used tires, then call to confirm your selection. If you notice pulling or uneven wear, mention it when asking about wheel alignment in Jersey City so the concern can be assessed.
