Load Index
Load Range


Safety Rating is a combination of two values: Load Index and Speed Rating for P-Metric and Euro Metric tire sizes; and Load Range and Speed Rating in the case of heavy duty LT (light truck) sizes.

Speed Rating is based on the speed that the tire is designed to be driven at for extended periods of time. All tires in the in the U.S. are designed to maintain legal U.S. speed limits. The speed rating of tires must match the maximum driving speed of the vehicle.

Load Index is used on P metric and Euro Metric sized tires and denotes a tire's load-carrying capacity at a specified inflation pressure. The load index is represented by a number, the higher the Load Index Value the greater the load the tire can safely carry. Vehicle manufacturers recommend a maximum load capacity based on a recommended minimum load index.

Tire Class


Tire Class reflects how the tire will be used. There are four major categories: All-Season, Max Performance, Summer-Only and Winter-Use.

All-Season tires are suitable for year-round driving in all weather conditions.

Summer-Only & Max Performance tires are specifically designed for high-performance driving. Tire compound, tread design and speed ratings all combine to hug the road and maintain grip. Summer tires by nature are not ideal for winter driving due to lack of siding to grip winter roads.

Winter-Use tires have tread compounds and patterns that are specially designed for grip on snowy or icy road surfaces. They are not suitable for year-round use. The rubber compound used will wear more quickly on dry, summer roads. It is recommended that winter tires are fitted as a complete set to avoid potential handling issues.

Tread Type


Tread Type is an important consideration when choosing a tire. There are four main types: Passenger, Highway, All-Terrain and Mud-Terrain.

Passenger denotes a tread that is suitable for normal use, a good all-round tread for normal driving.

Highway is a tread type unique to SUV and truck tires. The tread is optimized for normal everyday driving on paved surfaces. These tires can be driven off pavement, but are not ideally suited for off road traction. Highway tread patterns deliver a quiet ride.

For light trucks and specialty vehicles, All-Terrain tread types provide better off-road traction than standard highway truck tires. There more aggressive tread tends to be less quiet on paved roads. All Terrain tires are suitable for everyday use.

Mud-Terrain treads are specifically designed with wider tread blocks and higher void ratios to gain traction in off-road conditions. Mud Terrain tires can generate higher noise levels and tend to carry lower mileage warranties than other tread designs.

UTQG - Uniform Tire Quality Grade

UTQG (Uniform Tire Quality Grade) is made up of three values: treadwear, traction and temperature.

Treadwear is a relative numeric score, based on manufacturer tests, showing how well a tire can be expected to wear compared to other tires. A higher score means a tire could be expected to wear better.

Traction measures the tire's ability to stop a vehicle on wet roads. It doesn't reflect a tire's acceleration, cornering, or hydroplaning performance. Traction grades range from AA (highest) to C (lowest).

Temperature grades the tire's ability to withstand heat build-up, with A being the highest grade and C the lowest.

A - Over 115 mph
B - Between 100 to 115 mph
C - Between 85 to 100 mph
Traction Asphalt - gForce
AA - Above 0.54
A - Above 0.47
B - Above 0.38
C - Less Than 0.38
A - Over 115 mph
B - Between 100 and 115 mph
C - Between 85 and 100 mph

Drive / Ride Performance Characteristics

All tires have the following six performance characteristics, divided into three sets of trade-offs. In most cases, a tire may perform excellently in one characteristic but only standard in the other.
Standard Ride Comfort & Standard Handling
Handling: Get stiff side wall for precise steering and cornering but settle for a firm ride with increased road noise.
Ride Comfort: Enjoy a quiet, smooth ride but lose some cornering ability.
Standard Treadwear & Standard Traction
Traction: Stop faster in wet conditions but expect a shorter tread life.
Treadwear: Get long, uniform wear across your tread pattern but expect less traction in wet conditions.
Standard Low Rolling Resistance & Standard High Speed Performance
High-Speed Performance: Get increased performance at higher speeds but sacrifice some fuel economy.
Low Rolling Resistance: Enjoy improved fuel efficiency but expect less high-speed cornering ability.

Rated 4 out of 5 by Great On time and good service Ill do it again.... Haven't run the tire yet but I will find out in the fall when on the trip to Florida... August 27, 2015
Rated 5 out of 5 by great wear characteristics I use these tires on my 28 foot tandem axle trailer. They were incredibly well! I do not have to rotate them near as often as I have other tires. The ride is smooth. No complaints whatsoever. October 17, 2014
Rated 5 out of 5 by 2011 32' Toy Hauler Tires and Service I have been using Pep Boys for most of my service needs, so when it came time to replace my trailer tires LRE ST225/75R15 I replaced them with the Carlisle tire from Pep Boys after about 30,000 miles on the original tires. Just had a side wall bubble after about 30,000 more miles. The tire showed little wear at all. They replaced the defective tire prorated at $15. The mounting and Road hazard cost another $40 but they did a great job. Larry is the service manager at the Pep Boys in Chino Hills and makes me feel happy to go to Pep Boys. Thanks Larry and Robert.

Rated 5 out of 5 by excellent load range e in a 15 inch trailer tire great service, I ordered on line and picked up the tires the next day. Everything was ready when I got there and i paid for the tires and I was out the door in 10 minutes. August 5, 2014
Rated 4 out of 5 by Just as advertised Received the product quickly and in great shape. Since it is a spare, I hope I never have to use it. October 28, 2013
Rated 5 out of 5 by Great Service Here's a rare example of great service. I took a trailer rim in for a new tire and metal valve stem. The rim had a small dent in it when it was running on the rim when the tire blew. The guys there and manager were working fast and efficient. They fixed the dent (no charge) mounted the tire and shook my hand when I left. September 4, 2013
