The 120/116R is the service description..."<br /><br />I would recommend just changing the text for future people who read this (stick with Q, its less confusing) - and then deleting this comment I am leaving ;)Bakarihttps://www.blogger.com/profile/04002145755975841287noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-76553903293895728842012-04-16T13:59:30.778-07:002012-04-16T13:59:30.778-07:00Let me try again.

There is no chart as they all have a speed limit of 65 mph. There is no requirement to label those tires with a speed symbol.<br /><br /><br />Hope i was a bit clearer this time.Tireman9https://www.blogger.com/profile/09813984937064446653noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-74481495730682012312012-04-16T10:30:58.734-07:002012-04-16T10:30:58.734-07:00I'm thoroughly confused by the 'example...I'm thoroughly confused by the 'example' quoted in your article. It shows a number, LT235/85R16 LR-E 120/116Q, then breaks it down to 120/116R with the “R” as the speed symbol for 99 mph max. "A class A motorhome might display 255/70R22.5 LR-G 138/134L. The “L” is the speed symbol for 75 mph. Are you saying that the letter R is for 99 mph and the letter L is for 75?<br /><br />You further say at the end, "Finally: That ST type tires...are rated at 65 mph maximum". Is there a chart somewhere that lists these symbols and what they mean?Desertmanfredhttps://www.blogger.com/profile/03637457453007577064noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-70489962332836036222012-04-14T15:31:53.526-07:002012-04-14T15:31:53.526-07:00Well Penny, you are paartially correct. The "...Well Penny, you are paartially correct. The "R" just before the wheel diameter does mean Radial. If you see a "D" that means "Diagonal" or a bias ply tire which is an older construction.Tireman9https://www.blogger.com/profile/09813984937064446653noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-87404936930361588852012-04-14T11:37:19.165-07:002012-04-14T11:37:19.165-07:00Gee, and I always thought the "R" stood ...Gee, and I always thought the "R" stood for Radial.Pennyhttps://www.blogger.com/profile/15850652397085824819noreply@blogger.com
