In order to ensure the safety of real winter countries, the marking 3PMSF (Three Peak Mountain Snow Flake) has been established; the recognizable Alpine symbol of a snowflake on the background of the three peaks. This is the only reliable symbol that confirms winter properties of the tire. Models with this marking are suitable for demanding winter weather and they do not lose their properties at temperatures below zero. The standard and the EU-controlled mark 3PMSF is a guarantee that the product meets the conditions of the strict tests and is suitable for use in extreme weather conditions.
The code "MS" stands for "Mud & Snow". The manufacturer wants to indicate that the car tyre can take a beating. The tyres are deemed suitable for maintaining sufficient grip in wet, cold and muddy conditions.
Unfortunately, this does not mean that your truck tyre is also officially an approved all-season tyre or even a winter tyre.
The rolling of tyres on the road generates noise. How loud this noise is, is measured in decibels (dB). There are 3 sound classes: 1 sound wave shows that the tyre produces little sound. 2 sound waves show that it is an average tyre and 3 sound waves show that it is a tyre that produces a lot of sound. A 72 dB tyre makes twice as much noise as a 69 dB tyre. Every increase of 3 dB is in fact a darkening of the sound.
The "Grip" label shows the tyre's braking ability on wet roads. The rating runs from A (high wet grip) to G (very low wet grip). Tyres with high grip are more likely to bring the vehicle to a stop than tyres with less grip.
Depending on the rolling resistance of your tyre, the fuel efficiency rating varies from A, the most fuel-efficient tyre that saves you fuel, to G, the least fuel-efficient tyre that consumes the most fuel.
