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.
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.
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.
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.
