Does tire load rating matter?

Why Is Tire Load Index Important? The tire load index tells you how much weight your tire can carry, and overloading your tires is never a good idea! When you put too much weight on your tires, you can cause damage and wear them down prematurely. Even worse, you run the risk of experiencing a tire blowout.

Does load index matter on tires?

The higher the tire's load index number, the greater its load carrying capacity. Choosing a tire with a lower load index than the original equipment specifications means that the tire will not carry the load capacity of the original.

Is higher load rating tire better?

If you're thinking about up-sizing, you can switch to a tire with a higher load index, because that means your tire can safely carry more weight, but you can never go down.

Can I use a tire with a lower load rating?

No, under no circumstances can you use this tire. It is not safe. As sidewall height goes down, load carrying capacity goes down as well. Your OE tire has a load index of 111 (2,403 pounds per tire).

How does load rating affect ride?

Within the load index of a specific tire, one adjusts the tire pressure to achieve the desired load capacity; that tire pressure will also affect ride comfort and wear patterns on the tread (too high a pressure, and the tread will wear faster in the middle than at the side; too low a pressure, and the tread will wear ...

How important is wheel load rating?

Your wheel's load rating or weight capacity is an extremely important aspect of vehicle safety. The load rating determines how much weight your tires can safely carry at maximum air pressure.

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 is a good load index for tires?

The higher the tire's load index number, the greater its load carrying capacity. Choosing a tire with a lower load index than the original equipment specifications means that the tire will not carry the load capacity of the original. Most passenger-car tire load indexes range from 75 to 100, but some are higher.

Why do some tires have 2 load ratings?

Passenger vs.

The light truck tires have two load index ratings because light truck tires are often used on vehicles with dual rear wheels. As an example, if the tire's dual load index is 120/116, the load capacity for a single tire is 3,086 lbs and the load capacity for two tires is 2,756 lbs.

Can I use H-rated tires instead of V?

A V-rated car requires a tire designed to operate to a maximum of 149 mph and can thus not be fitted with an H-rated tire.

Can I use T rated tires instead of H?

A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h). It is important to note these markings and stay within those speed limits.

Can I use W rated tires instead of V?

V means that vehicles can safely use the tire with a top speed higher than 149mph. The rating W shows that the tire is safe to use for a vehicle with a top speed of 168mph.

What's better load range D or E?

Expert Reply: Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically the only difference between the two is the weight capacity.

Can I use ZR tires instead of R?

R indicates that the structure is RADIAL. So, VR indicates that the tyre has a RADIAL structure and a speed index equal to V. There is therefore no difference between a ZR or an R tyre with the same speed index.

What is the difference between Load Range E and F?

The difference between a load range E and load range F tire of the same size, 235/85-16, is the weight capacity and pressure. The Karrier Radial Tire, Load Range E, # AM10295, has a capacity of 3,640 pounds at 95 psi. The Load Range F Tire, # AM10501, has a capacity of 3,960 pounds at 95 psi.

Is Load Range D better than C?

A load range D tire may carry more weight than a load range C tire when properly inflated. At 65 psi, load range D tires can carry about 1,610 pounds, whereas load range C tires can carry 1,360 pounds at 50 psi.

Do I need 10 ply tires?

Understanding the tire ply rating system helps you understand how your tires support the weight of your vehicle (called load range or load index). If you drive a ¾ ton, one ton or even larger pickup or SUV (or haul a trailer) then you require 10-ply tires.

What does T & H mean on tires?

Speed rating. This letter denotes the maximum sustainable speed and is found directly after the load index. For S-speed-rated tires, it's 112 mph; for T, 118 mph. Speed ratings for other tires include Q, 99 mph; H, 130 mph; and V , 149 mph.

Should I put 80 psi in my tires?

The 80 psi is required if the tire is operating at rated load. You most likely have a load range E tire.

Should I increase tire pressure for a heavy load?

An increased pressure reading (typically 2 to 6 psi higher) is normal when tires are hot. If recommended by the vehicle manufacturer, increase tire pressures for towing, carrying heavy loads, or extended highway travel.

Are E rated tires 10-ply?

E-Rated Tires: Wrap Up

To conclude load rating E means that it's a 10-ply tire that can handle up anywhere between 60PSI to 85PSI when carrying the max load. To know the maximum weight capacity of a tire, you'll need to check the load index. The higher the number, the more weight it can hold up.

Do 10-ply tires ride rougher?

Yes, it will. The other downside is 10-plies are substantially heavier, which will drop your fuel mileage (you're going from low 40s lbs/tire to mid 50s). There are a fair number of P-metric 275/60R20s out there (with the Defender LTX M/S being one of the best options).
