Question: Does Load Rating Matter On Tires?

Do tires with higher load rating last longer?

Expert Reply: Going to a tire with a higher rated load range will mean you will need a higher psi rating.

The problem with going to a higher rated tire is that it may result in a stiffer ride..

What does 400 AA mean on a tire?

“UTQG” stands for “Uniform Tire Quality Grading”. A system developed by the Department of Transportation, which helps consumers compare and rate tires on tread wear, traction, and temperature. … So the tire rated at 400 would wear four times longer than the government’s mandated tire.

What does load rating mean on tires?

Tire load index is an assigned number that corresponds to the maximum weight that a tire can support when properly inflated. The higher the tire’s load index number, the greater its load carrying capacity.

Should all 4 tires be the same brand?

For optimal safety and performance, it is recommended that vehicles are fitted with the same tires to every wheel position on your car. That means having the same brand, size, tread pattern, load index, and speed rating on the front and rear tires. However, there are exceptions that can lead to mixing tire brands.

Can you have 2 different brands of tires on your car?

We recommend that the same tyres are fitted on all wheel positions of your vehicle. If however, due to availability or economical considerations, mixing is necessary then it is permissible to mix brands and tread patterns as long as the same tread patterns and brands are fitted across the same axle.

How many miles is a 500 treadwear rating?

80,000 milesA tire with a treadwear rating of 320 should last for approximately 40,000 miles. This is a lower-middle level treadwear rating. Tires with a high-end rating of over 500 should deliver approximately 80,000 miles.

Can I use a tire with a lower load rating?

Can you use a tire with a lower load index? No. A tire with a lower load index than your OE specifications can’t properly support the weight of your vehicle and its load (passengers and ski equipment, for example)—or the forces applied to the tire in emergency manoeuvres.

Can you mix load rating tires?

You can mix tires if you install identical pairs on the same axle (i.e. front, rear). You can mix tires with varying speed ratings or load indexes, granted that they exceed the manufacturer’s minimum recommended threshold. … For better handling, any new tire with deeper treads should be fitted to the rear axle.

Should I get V or H rated tires?

To support running at higher speeds, V-rated tires will have a stiffer sidewall and slightly firmer ride than H-rated tires. For normal driving conditions the H-rated tire will provide a more comfortable ride and the V-rated should give slightly better handling.

Does tire speed rating affect ride quality?

Speed Ratings Refer to More Than Just Speed Speed ratings affect more than just speed, they also contribute to ride comfort, wear, and cornering capabilities. In general, the higher the speed rating, the better the grip and stopping power, but the lower the tread life.

Is a higher load rating better?

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.

What is the best traction rating for a tire?

The traction grade looks at the level of grip on a wet surface. Most ultra-high-performance tires achieve the best grade: AA. Most car tires get the next best grade of A; less than 22 percent of the tires have a B grade; and only one tire (out of more than 2,400 models) has the honor of a C grade.

Do all 4 tires have to match?

Ideally, you want all four tires to match in both type and wear, but a set of mismatched tires isn’t a deal breaker, so as long as they meet the following criteria: … A car with mismatched front and back tires should still be usable, especially if it is a two wheel drive vehicle.
