Wet grip B
B
EU tyre label — wet gripShort wet braking, one step off the best. Grade 2 of 5, A to E.
A grade most premium tyres reach; the step from B to A is where the engineering gets expensive.
C1–C3
Only comparable within one classA truck tyre's B is not a car tyre's B
Car (C1), van (C2) and truck (C3) tyres are graded against different thresholds, so the same letter means a different measured result on each. Compare like with like.
Label
Where to find itOn the label, not the sidewall
This grade is on the sticker that comes with the tyre and in the seller's listing — it is not moulded into the rubber, so there is nothing to look for on the wall. See the whole label, part by part.
