前言

本文件按照GB/T1.1—2020《標(biāo)準化工作導(dǎo)則第1部分：標(biāo)準化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T2978—2014《轎車輪胎規(guī)格、尺寸、氣壓與負荷》，與GB/T2978—2014相比，除

結(jié)構(gòu)調(diào)整和編輯性改動外，主要技術(shù)變化如下：

——增加了高負荷轎車子午線輪胎標(biāo)志要求和，并更改了需要標(biāo)記“RF”或“ZRF”的輪胎類型引

用了GB/T30196—2022相關(guān)規(guī)定的說明（見第4章，2014年版的第4章）；

——刪除了保留生產(chǎn)的轎車斜交輪胎（見2014年版的第4章及表15）；

——增加了部分轎車子午線輪胎規(guī)格（見表1~表12，表14）；

——增加了部分規(guī)格的增強型負荷指數(shù)及負荷能力（見表1、表3~表9、表11，2014年版的表1、

表3~表9、表11）；

——增加了部分規(guī)格的標(biāo)準型負荷指數(shù)及負荷能力（見表6~表9、表11，2014年版的表6~表9、

表11）；

——更改了部分規(guī)格的個別數(shù)據(jù)參數(shù)（見表1~表12、表14，2014年版的表1~表13）；

——增加了高負荷轎車子午線輪胎（見表13）；

——供臨時使用的T型備用輪胎部分規(guī)格增加輕負荷型（見表14，2014年版的表13）；

——增加了T型備用輪胎的測量輪輞及允許使用輪輞要求（見表14，2014年版的表13）；

——更改規(guī)范了對充氣壓力的要求（見5.5，2014年版的5.5）；

——刪除了部分速度符號和最高速度的對應(yīng)關(guān)系（見表B.1，2014年版的表B.1）；

——增加了新胎最大最小外緣尺寸計算及修約規(guī)定（見附錄C）。
