BRIDGESTONE VMTS 27.00R49 2* E4

Tire TKPH varies depending on the tire’s design (size, tread pattern and the type of compound). A High TKPH tire generates less heat than that of lower TKPH tire. However, the lower TKPH tire will have greater cut and wear resistance than the higher TKPH one. The TKPH method is applicable in the following situations.

(1) One way distance: within 16 km (10 miles) a. When haul length exceeds 16 km one way, consult a Bridgestone Representative. b. If the round-trip distance is less than 5km (3miles), Tire TKPH figures can be increased by 12%. (2) Ambient temperature: 38˚C (100˚F) For ambient temperatures other than 38˚C (100˚F), the Tire TKPH rating should be revised based on the following formula. Radial Tire Revised TKPH rating = [1 + α × (38˚C–Max. Ambient Temperature ˚C)]* × Tire TKPH Below 27.00 (33.5) inches in Section Width: α =0.010 Above 30.00 (37.25) inches in Section Width: α =0.00

(3) Maximum speed a. Radial Tire For 65km/h(40mph) maximum speed, the loads must be reduces 12% with no change in inflation pressure. b. Bias Tire When the maximum speed exceeds 50 km/h (30 mph) under loaded conditions, the following formula is used: Revised TKPH Rating = 50 km/h × Tire TKPH Max. speed Example: The TKPH Rating for 21.00-35, 36PR RLS E1A is 226; if the tire is to run at 60 km/h when loaded. 50 × 226 =188 60 (4) To obtain the TKPH(TMPH) for type 2A-LS, multiply type 2A rating by 0.8. (5) The respective types of vehicles are subject to the following speed limitations
