How to Read a Tire Size

What does load range 121 mean?

The load rating of the tire displays the weight a tire can carry. The product of the load capacity of a single tire and the number of tires determines the load carrying capacity of all the tires combined. The rating of 121 shows that it has a load capacity of 3297LBS.

Now comes a comparison of E1 vs E2 load range. As I feebly understand Discount Tire's own material, E-rated tires sized 305 and up carry an E-2 load range and a max inflation of 65 psi while E-rated tires sized below 305 carry an E-1 load range and a max inflation of 80 psi.

What load range is a 12 ply tire?

Tire Ply-Ratings

What does 121 118s mean on tires?

R – Designates the tire has radial construction. 17 – Wheel Diameter. 121/118 – Load Index. S – Speed Rating.

Can I use a lower load index tire?

What does 125s mean on a tire?

125 denotes that each tire can carry 3638 pounds at the maximum inflation pressure. The second number (122) refers to the load rating on a single tire used in a dual rear wheel application. “Q” refers to the tire's speed rating. In this case, the tire is rated at 99 mph for continuous use.

What is a 123 tire load index?

The first rating of 123 means that if the tire was the only tire on that side, it could haul up to 3417lbs. If one tire was to fail, the single tire would be able to support the load of the vehicle. If you don't have a dual-wheel rear axle, that is also the main number you focus on.

Is a higher load index better?

6) Load index

The higher the number, the higher the load it can safely handle. As an example, a tire with a load index of 89 can safely handle 1,279 pounds — while a tire with a load rating of 100 can safely handle as much as 1,764 pounds.

Does tire speed rating matter?

One of the most important aspects of any tire is its speed rating. The wrong tires with a less-than-adequate speed rating for your vehicle can cause safety issues, including tire failure and a loss in fuel efficiency.

What does the E stand for on tires?

E-rated tires refer to the load rating, which is how much pressure the tires can handle at max load. This rating is only used for Light Truck tires.

LT tires are usually 8-ply (Load Range D) or 10-ply (Load Range E). Passenger Tires usually have a 4-ply or 6-ply equivalent sidewall. The performance trade-off of this added weight is a harsher ride, less fuel efficiency, and less responsive handling.

What load rating do I need?

To roughly determine the load range capacity for each individual tire, take the vehicle's gross weight and divide by four. If the vehicle gross weight is 4,500 pounds, each tire should be able to safely support at least 1,125 pounds.

What's the best speed rating for tires?

As manufacturers developed bigger and better tires, it became necessary to regulate performance at standardized speeds to ensure safety. The "Limited V" category of 250 km/h (149 mph) was then created, and eventually the "Z" speed rating was added as the top speed rating.

How much weight can a load range D trailer tire carry?

The D load range is rated for 2,540 pounds at 65 psi. And the E load range is rated for 2,830 pounds at 80 psi. If you had a single axle trailer with a gross weight rating of 5,000 pounds, you would use the D or E tires in this size since the C tires would be under rated for the weight.

What ply tire is Load Range C?
