What does 109t mean on a tire?
The load index number, 109, refers to the weight the tire can carry, in this case, 2271 lb. However, the load index is not a linear function (refer to the chart for common values). A load index of 120, which might be found on a 3/4-ton HD pickup, carries twice the weight of a load-index 95 tire.
How do you read a tire date code?
The last four numbers represent the manufacturer’s date. The first two numbers indicate the week, while the last two indicate the year. (For example, a tire with the number 2910 was manufactured in the 29th week of 2010.)
What does 91V mean on a tire?
Speed rating
The rating system uses letters from A to Z. Here, you can see that a tire with a 91V mark can them run at a maximum speed of 149 mph while carrying 615 kilograms or 1,356 pounds load.
What does 94v mean on a tire?
A 94 will support 1,477 pounds. V is a speed rating, or the maximum speed tires are designed to be driven for extended periods. Any V-rated tire will perform well while traveling at 149 miles per hour for an extended time — certainly fast enough for this writer.
How much weight can a 10 ply tire hold?
Tire Weight / Tire Pressure = Load Capacity Pounds per PSI
At 60 psi on a 10ply tire, the tire’s load carrying capacity is reduced to 2,314 pounds per tire. If the customer runs 65 psi in a 10 ply tire, his capacity is now able to carry 2,507 per tire.
Should I get H or V rated tires?
If you feel the need to drive at or above 130 mph then you should get a “V” speed rated set of tires. If you don’t plan on driving that fast, then an “H” speed rated set is the better option.
How many years do tires expire?

Do H or V-rated tires last longer?
Generally, tires built for higher speeds have a lower tread life. Therefore, V-rated tires will not last as long as H-rated tires. However, both of these tires generally last about the same amount of time – given that their maximum speed is pretty close.
What does 91v and 91h mean on tires?
The speed symbol (GSY) “V” – indicating the maximum permissible speed – is indicated right after load rating “91”. In this case, the tyre is V-rated, i.e. approved for speeds of up to 240 km/h. Other common speed symbols are T (up to 190 km/h), H (up to 210 km/h), W (up to 270 km/h) and Y (up to 300 km/h).
How long do V-rated tires last?
V-rated tires had an even shorter tread life of 48,260 miles. Mileages are projected to wear-out, based on Consumer Report 16,000 mile wear tests.
Should I get H or V-rated tires?
Which is better 10-ply or 12 ply?
10-ply tires are more than enough for most situations while also being more comfortable, cheaper, better-performing, and use less fuel. On the other hand, 12-ply tires are more durable, are better with towing and hauling, and should be able to tackle challenging terrains better.
Is a higher ply tire better?
The more ply, the more sidewall strength. When your sidewall isn’t strong enough, the load squashes the tires down into the road. The tread then pushes into the ground and spreads out in a way that was never intended by the manufacturer, leading to a blowout.
Do H or V rated tires last longer?
Can I mix H and V rated tires?
Just remember, never mix and match tires with different speed ratings on your vehicle. This will cause major problems with the handling of your vehicle. If tires of different speed ratings are mounted on a vehicle, the lower speed-rated tires should be placed on the front axle, regardless of which axle is driven.
Are 7 year old tires still good?
Some automakers suggest that tires be replaced as soon as they turn six years old. Some tire experts contend that tires can last anywhere from six to ten years if they’re stored and cared for properly. We recommend replacing tires aged 6-10 years, no matter how much tread remains.
Are 10 year old car tires safe?

Do tires expire if not used?
/General information /Tire care and maintenance /Tire Safety /How Long Do Tires Last if Not Used? If not used, tires last for 6-10 years, depending on the storage and environmental conditions. Overall, the time limits for stored tires are much the same as for tires that are being used.

What happens if you go faster than tire speed rating?
What happens if you exceed your tire’s speed rating? If you drive faster than the rated speed for your tires you are risking damage to the tires that could cause safety and performance problems down the road.
Can I use H-rated tires instead of V?
If you head to the maximum speed limit at 130-mph, you can choose H-rated tires. Meanwhile, the corresponding number of the V-rate tire is the limit at 149-mph. Each type of tire has a different top speed, and substituting a lower for a higher is often not good for the vehicle.
