Đồng hồ đo độ cứng cao su, lốp xe đua PTC model 306RL
Our racing tire durometer was designed to produce accurate results each time to give you the edge for your rally, motocross, drag, kart, F-1, Nascar, etc. Drivers routinely refer to tires as "hard" and "soft," hard tires supposedly being the norm for a newly repaved race track. Many race tracks rely on tire durometers that are used to measure the indentation hardness of the tire.
These durometers can be customized with your team name and/or drivers name and number!
For hardcore racers, the durometer has 2 primary functions:
1. Tires matching. Even the same brand and model tires can have variances (older tires get harder just sitting on a shelf and doing nothing). There can also be batch to batch variances so to ensure maximum consistent, predictable performance, racers will test tires to make sure that a set measures the same durometer (the term is both used for the tool and the measurement) before mounting them.
2. They then track the changes in durometer over the life of the tire (assuming you don't wear them beyond usable life first), and note the changes in grip so they know when to change the tires to retain the maximum grip and handling and when the tires have exceeded their heat cycle life and are now costing them time.
