Below is some tyre jargon you might have overheard somewhere but you did not know what it means.
High Performance Tyres
High Performance tyres are tyres made to achieve a better transfer of energy from the vehicle to the road. This gives them a better acceleration and top speed than would be achieved with general market tyres. This increased performance can be significant but it comes at the cost of nearly everything else, high-performance tyres are made from soft rubber compounds so that they get lower tread wear ratings and a shorter lifespan.
All Season Tyres
All season is a manufacturer determination that their tyres are capable for performing in year round weather. This normally means that sacrifices have been made to allow them to perform at below freezing conditions. The idea is to design a tyre in which these sacrifices are small enough that the benefit of not having to change tyres for winter outweighs the cost. Technology has improved to the point that many current all season tyres perform at the level a high performance tyre would have in the past. Though in comparison to contemporary tyres, the technology for other types of tyres has also improved and so all season tyres are still a convenience measure.
Often these tyres are aimed at a target market that is more interested in utility over performance and therefore they are also designed for quiet comfortable ride.
An early tyre that was marketed as an all season tyre was the Goodyear Tiempo and it is from that marketing campaign that the concept of all season tyres would grow. With the slogan "Snow tyre, rain tyre, sun tyre; one tyre does it all!", it was a very successful tyre and other companies would look to develop their own products in this range.
Tire Studs are generally metal screw in points and are used to improve the grip in winter conditions. These studs help tires dig into ice and can yield improved traction. When there is no ice on the road however they can do a lot of damage to road surfaces and for this reason there are often regulations on their use and in some cases complete bans. Tire studs are usually installed into tires with stud points using a pneumatic tool that screws the studs deep into the rubber of the tire surface.
