What is the difference between a "performance tire" and a "passenger-highway" tire?

Question

I am shopping for new tires for my GMC Jimmy. I only use it on the road - no towing or crazy off-road stuff. I am confused about the different tire types... performance, passenger-highway, passenger-standard, light truck-highway, light truck -standard, etc. How do these types differ? THANKS

Answer 1

typically in the thread patterns and their materials. Performance tires for sports cars usually have an aggressive tread pattern...one that will offer the most traction and stability in the wet. They also come in softer materials, increasing grip but shortening their lives.

A standard highway tire will have a fairly standard tread pattern and a harder material. It'll be meant for quiet on the highway and fuel economy.

Answer 2

Automobile tires are produced in several styles with different cord construction and rubber compounds. Different styles offer some differences in smoothness of ride, and in the grip on the road for cornering, braking and acceleration.

"Performance" tires are normally wider than standard, with softer rubber compounds, for better grip on the road, but they will also wear out faster in daily use. Passenger highway and standard tires are usually built for a smoother ride on the highway, and a bit harder rubber for better tire wear and a longer service life. Light truck tires are generally built to carry heavier loads, and will also give a harsher ride, but longer tread life. There are also different tread patterns from standard highway treads to rain and snow treads.

The original tires that came with your Jimmy were probably a general-purpose mud & snow rated tire with good all-season performance and tire wear characteristics. If you have been happy with the performance and durability of your original tires, then you should replace them with something similar to what you have now.

Hoo boy....got a couple of hours?

Seriously though, you do not need performance-type tires on this vehicle. In North America P-metric tires, as opposed to LT-metric, have speed ratings. "S" or "T" speed rated tires are considered passenger tires. "H", "V" and "Z" speed rated tires are considered performance tires. You can find this on the sidewall of the tire, in the service description, e.g. P235/70R15 91T.


What to buy? Ask a qualified tire professional in your area for advice. Be sure that you give preferences i.e.: ride comfort, longevity, price,noise, etc. If you are specific in your wants and needs, you will drive away happy.
