What does 91h on a tire indicate?
1 Answers
91h on a tire indicates a maximum load capacity of 615kg per tire and a maximum speed of 210km/h under specified load conditions. The reasons for insufficient tire pressure are: 1. Air leakage from the tire valve; 2. Reduced tire sealing performance due to wheel hub deformation; 3. Uneven tire force distribution. The hazards of insufficient tire pressure include: 1. Increased road friction coefficient, leading to higher tire temperatures and potential tire blowouts; 2. Heavy steering wheel, compromising driving safety; 3. Damage to the tire bead. Solutions for insufficient tire pressure: 1. Replace the tire; 2. Rotate tire positions.
