overall diameter

The overall diameter of produced tire was in accordance with the relevant national standard, and the speed performance and endurance of tire were improved significantly.

该轮胎的外缘尺寸符合国家标准要求，轮胎的高速性能和耐久性明显改善。

It is confirmed by the in-door test of finished tire that the overall diameter of inflated tire meets the requirements of the TRA standard and the design, and the performance of test tire is very good.

成品轮胎室内试验表明轮胎充气外缘尺寸符合TRA标准和设计要求，且性能良好。

The main measures are as follows: the overall diameter is reduced from 808 mm to 798 mm and the cross section width is reduced from 198 mm to 195 mm;

采取的主要措施是：减小轮胎外缘尺寸，外直径由808mm减至798mm，断面宽由198mm减至195mm；

The inflated overall diameter, endurance and plunger energy of the optimized tire met the design targets.

优化设计后轮胎的充气外缘尺寸、耐久性能和胎体压穿强度均达到了设计要求。

The inflated overall diameter and endurance of finished tire are in accordance with the requirements of the design and the relevant national standard.

轮胎充气外缘尺寸和耐久性能等达到设计要求和国家标准。
