[0093] Based on the specifications in Table 1, a trial-manufactured form figure 1 The basic structure of figure 2 The basic pattern is a heavy-duty tire of size 11R22.5. The wet performance and uneven wear resistance of each test tire were tested. Common specifications and test methods for each test tire are as follows.
[0094] Mounting rim: 7.50×22.5
[0095] Tire internal pressure: 800kPa
[0096] Test vehicle: 10t truck
[0097] Tire installation position: all wheels
[0098]
[0099] The above-mentioned test vehicle drove into a wet asphalt road with a water film of 2 mm thickness at a speed of 65 km / h, and braked suddenly. At this time, the deceleration time of the test vehicle from 60 km / h to 20 km / h was measured. The result is an index with the value of Comparative Example 1 being 100, and the smaller the value, the shorter the deceleration time and the better the wet performance.
