What does wet grip C mean?
Reduced rating levels: Fuel efficiency and wet grip are now rated in 5 levels (from A to E) instead of 7. External rolling noise is rated from A (lowest noise level) to C (highest noise level)

What is a good tire traction rating?
A tire graded “A” is the highest, “B” is average and “C” the lowest. A tire having a higher grade should allow a car to stop on a wet road in a shorter distance than a tire with a lower grade. Traction is graded “AA” (highest), “A,” “B” or “C” (lowest).
Does more surface area increase grip?
Traction, or the grip of a tire on the road surface, can actually be improved by increasing the size of the contact patch. A larger contact patch increases the chances of the maximum coefficient of friction being achieved between the car tire and the uneven road surface.
Do wider Tyres give more grip?
From a safety point of view, both types have their good sides: On a dry road, wider tires will offer more grip than narrow ones, but the risk of aquaplaning will be higher with wide tires. – In the winter, narrow tires are better under extreme conditions as they provide higher surface pressure against the road.
What does tyre wet grip mean?
Wet grip The wet grip rating indicates how well the tire will perform in wet conditions, with performance graded from class A down to E. A high grade means short braking distances on wet roads.
Why do softer tires have more grip?
softer tires have a larger coefficient of friction, therefore better traction. Wear in a tire is related to contact patch. Harder compound tires wear much longer, and can be narrower. They do, however have a lower coefficient of friction, therefore less traction.
Are soft or hard tyres faster?
“The softer a tyre is, the faster it wears.” During the usage a tyre gradually wears, leaving rubber on the tarmac. When a tyre wears, its grip, its stickiness starts to decrease. When the grip is lower, the car goes slower and lap times increase.
Is a higher treadwear rating better?
Tread wear (the durability rating) This number designation is designed to give you a picture of the durability or life you can expect from your tire. The higher the tread wear number, the longer the tread wear will last. In this case, a higher number is better than a lower number.
What are the specs for ultra grip tires?
Tire Prices vary based on specifications such as speed rating, load index and sidewall. The following are all of the sizes and specifications for the Ultra Grip ® Winter. Learn more about what each specification means in our tire glossary.
What are the mechanics of grip on a tyre?
The mechanics of grip are to be explained by the astonishing visco-elastic properties of the tyre’s rubber which within the contact patch produce a host of physical phenomena that strive to counteract any untimely skidding over the road surface. Page 4 Page 5 Grip
What kind of surface can Prismo tyregrip be used on?
It provides a well textured surface typically 5mm thick for the standard road grade and 2-3mm thick for the pedestrian grade. The system can be readily applied to asphalt, macadam and concrete surfaces providing the latter is suitably primed.st applications.
How do you know the size of a tyre?
Tyre have a code system moulded into their sidewall which allows you to understand their technical capabilities. This code provides information on tyre size, construction (e.g. radial), its load-carrying capacity and its speed rating.
