2 in 1 tire tread depth gauge is a pen gauge for both tyre tread depth measurement and brake pad thickness measurement. It is suitable for all kinds of vehicles, such as car, SUV, MPV, RV, ATV, truck, motorcycle, agricultural vehicle, engineering vehicle, etc.
||Tread depth: 0-15mm
Brake pad thickness: 0-20mm
||Tire tread depth measuring, brake pad thickness measuring
||Aluminum alloy, rubber
Tips: 3 points need pay attention when replace heavy worn tire
As we all know, the limit value of ordinary car tire wear is 1.6mm, that is, when the tire tread depth is less than 1.6mm, the tire must be replaced. There is a special triangle mark for wear warning on each tire.
When the tread depth of a certain tyre reaches the limit, is that enough just replacing the old tire with a new tire?
The answer is no. Under normal conditions, the tread depth differences of different tires cannot exceed 3mm when using combination of new and old tires. If the pattern depth difference exceeds 3mm, it means that the old tires are too old. It is recommended that all old tires be replaced with new tires. Therefore, it's better to check the tread depth of all tires with a tire tread depth gauge, and then confirm whether only one tire or all tires need to be replaced.
Automotive tires are rubber products, and aging will naturally occur over time. A tire can be used for four years when installed on a vehicle. After four years, the tire will be clearly aging. Even if the driving distance is relatively small in four years, a clear aging phenomenon may occur with four-year tires. The aging of tires will affect the deterioration of the grip and the extension of the braking distance, which will affect the driving safety. Therefore, do not buy tires with a factory date of more than three years.
Finally, after replacing the new tires, re-do a dynamic balance test for each wheel is necessary.
