What does 98Y mean on a tyre?
load index and speed symbol
For example, if your tyre’s sidewall markings were 235/45R18 98Y, the last section of the sidewall markings ’98Y’ indicate the load index and speed symbol. The first number, 98, refers to the load index of the tyre. The second letter, Y, refers to the speed symbol of the tyre.
How do you calculate tyre load rating?
You’ll find the load rating of your tyre on the sidewall, just to the right of the diameter. For example, a tyre with a load index of 91 can carry 615kg of weight. Load ratings and speed ratings should be looked at together when you buy a new tyre.
What is the meaning of 10.00 20 tyre?
20 inches, stands for the diameter of the wheel that the tyre is designed to fit. Radial construction. R stands for radial-ply construction. 10. 10 is the width in millimetres of the tyres cross section.

What does 4PR mean on tires?
ply rating
And this is how you read it: 3.00 = section width (inches) H = speed rating (see Speed Rating Chart ) 16 = rim diameter (inches) 4PR = ply rating.
What is a good tire load index?
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.
What does speed index mean on tyres?
The speed rating or speed index is represented by a letter and associated with the tyre’s maximum speed capability when operating at its maximum load carrying capacity. A tyre marked with a ‘Y’ speed rating, indicates it can be safely operated at a maximum speed of 300kph.

What is tyre SLR?
SLR Static Loaded Radius is the radius from the wheel centre down to the ground, at reference load and pressure. The difference between unloaded radius and static loaded radius is called deflection. This value varies between 15-30% of the tire section height, depending on tire type.

Which is better 6 ply or 8 ply tires?
Actually the 6 ply will last longer than the 8 ply. The reason is the extra size of the body plies in a trailer tire will actually produce more heat while rolling than a 6 ply rated tire. I definately recommend radila and not bias ply construction. Radial tires wear much better.
What is a 120 tire load index?
For example, a light truck tire with a load index of 120/116 means a load capacity for a single tire of 3,086 pounds and a load capacity of 2,756 pounds for two tires. The reason the capacity for two tires is lower than a single tire is to make sure that the vehicle can continue to carry the load should one tire fail.
What is a 121 load rating?
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.

Which speed rating tyre is best?
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.
What is the best speed rating for tires?
Everyday passenger vehicle tires can be S speed rated, but S tires often prioritize specific performance or function. An M speed rating indicates the tire has been approved for speeds up to 87 mph (140 km/h) and an N is approved for speeds up to just 81 mph (130 km/h) under optimal conditions.
