R21的尺寸选择，实现轮胎前窄后宽，让操控性能更好，同时小米YU7还有更多丰富的轮胎轮毂可选，能够满足续航、舒适、静音、运动的全方位需求，我们也会在后续详细介绍。责任编辑：振亭","kind":"news","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":0,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"hasMoreComments":false,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"isCrawlerRequest":true}
