Types of Tires Explained: Which Kind Fits Your Car

Three questions sort every tire

Tire listings throw a lot of labels at you: all-season, grand touring, A/T, UHP, run-flat, directional. They make more sense once you see they answer three different questions:

1. What climate is it built for? Summer, winter, all-season or all-weather.
2. What kind of driving is it built for? Touring, performance or all-terrain, plus light truck construction for heavy loads.
3. How does it handle a puncture? A regular tire or a run-flat.

A single tire answers all three. A "touring all-season" is one climate type and one driving type. Here's what each label means, in the tire makers' own terms.

By climate: summer, winter, all-season, all-weather

Michelin draws the line at 45°F:

Continental describes summer tires as having a dedicated rubber compound that delivers excellent grip and handling on both dry and wet roads in warmer conditions, and all-season tires as a hybrid of summer and winter characteristics.

Two sidewall marks tell climate types apart. Michelin explains that M+S means the tire is designed for mud and snow based on the manufacturer's criteria, while the three-peak mountain snowflake (3PMSF) means it met standardized testing requirements for verified winter performance. Our guide to all-season vs all-weather tires goes deeper on that difference.

In South Florida, the realistic choice is between all-season, all-weather and summer tires. Snow isn't the deciding factor; wet grip, heat and tread life are.

By the kind of driving: touring, performance, all-terrain

Continental's definitions:

• Touring tires are built for long-distance driving, offering comfort, low noise, and durability.
• Performance (sport) tires have tread patterns aimed at strong traction in wet and dry conditions. Michelin notes their stiffer sidewalls and softer compound, which wears faster.
• All-terrain tires are a good match for off-road use on larger SUVs and trucks, with aggressive tread patterns.

Touring and performance tires are the main split for cars and crossovers; see touring vs performance tires. For pickups and SUVs, the split is highway vs all-terrain vs mud-terrain, covered in all-terrain vs highway tires.

Light truck (LT) and passenger tires

Construction is its own type. The federal tire standard defines an LT tire as one designated by its manufacturer as primarily intended for use on lightweight trucks or multipurpose passenger vehicles, and requires its load range letter on the sidewall. Many all-terrain sizes are LT tires, which changes load capacity and inflation pressures. Our LT vs P-metric guide covers when a truck needs LT.

By puncture handling: regular or run-flat

Most tires lose their ability to carry the car once they lose air. A run-flat tire is built to keep going for a limited distance after a puncture. Continental describes it as remaining operational until the driver can reach home or the nearest garage. Run-flats carry their own speed and distance limits from each maker, and they need a working TPMS because they don't look flat. See run-flat tires for those limits.

By tread pattern: symmetrical, asymmetric, directional

Inside any category, the tread itself comes in three layouts. Continental describes them:

The mounting rule matters at rotation time: directional tires can't simply be swapped side to side on the same wheels. Our rotation pattern tool shows which patterns work for your setup.

Two more labels you'll run into

• Temporary spare. Michelin lists T at the start of a size as the mark of a temporary spare. It's a get-you-to-a-shop tire with its own speed limit and pressure printed on it; see spare tire types.
• EV tires. Many electric cars come on tires tuned for weight, quietness and low rolling resistance, sometimes with higher load ratings. They're still one of the climate and driving types above; our guide to EV tires explains what's different.

A quick way to narrow it down

That's a starting point, not the answer. The answer starts with your door placard.

Whatever the type, match the placard

A tire type is a choice. The size, load index and speed rating are not. Replacement tires should match the size on your door placard and meet or exceed its load index and speed rating. If you're not sure what your car takes, find my tires looks it up by vehicle, and you can then shop by size within the type you want.
