Can 84t and 84h tires be mixed?
2 Answers
Tires with 84t and 84h ratings cannot be mixed. For safe driving, tires installed on the same axle must be of the same brand, tread pattern, specification, load index, and speed rating. When replacing tires, the specifications must comply with the vehicle manufacturer's requirements and recommendations. This means the load index of the replacement tire must be equal to or greater than that of the original tire, and the speed rating of the replacement tire must be equal to or greater than that of the original tire. The only difference between 84t and 84h tires is their speed rating, which indicates the maximum speed the tire can withstand. Specifically, an 'h' rating means the tire can withstand a maximum speed of 210 km/h, while a 't' rating means it can withstand up to 190 km/h.
As a seasoned driver with years of experience, I strongly advise against mixing 84T and 84H tires. The number 84 refers to the load capacity, approximately 500 kilograms, which is generally sufficient for a car. However, the speed ratings differ: T indicates a maximum speed of 190 km/h, while H is 210 km/h. When these tires are mixed, their varying speed performances can lead to uneven handling—one side of the vehicle may have stronger support while the other responds sluggishly, resulting in unstable control or uneven grip. I’ve seen a friend do this, and it made the car prone to skidding in rainy conditions, increasing the risk of accidents. Safety is the top priority when driving, so I recommend checking your tires to ensure all have the same speed rating. If replacement is needed, replace all four tires with the same specifications at once. Regular maintenance, such as checking tire pressure and wear, can also extend their lifespan.
