message: In the European community, tires that are not fit for a car's or motorcycle's particular maximum speed are illegal to mount. The sole exception are M+S tires, where a warning sticker stating the allowed maximum speed must be placed within clear sight of the driver inside the vehicle.
I don't think this statement is correct for the whole EU. In Finland it is mandatory to have "winter" tires during Dec-Feb, but it is not regulated that any warning sign for lower speed rating tires is needed. —Preceding unsigned comment added by 80.81.162.66 (talk) 06:43, 30 October 2009 (UTC)
thread_title:  Tire maximum speed 

message: I plan to improve this article by adding references for unreferenced statements and clarifying the title. Tire codes can refer to the size of the tire and similar notations. However, the DOT code is very specific. It's the manufacturer, factory, and date code written in a string of letters and numbers. This isn't clear in the article but it will be after I work on it.

message: The article states "
 M+S, or M&S: ......A winter tire even if it doesn't have the snowflake and mountain symbol. Spike tires have an additional letter, "E" (M+SE). "
At least in Canada, in jurisdictions that mandate winter tires, a winter tire is ONLY a winter tire for legal purposes if it has the mountain and snowflake emblem. There is absolutely no comparison in performance between a M+S tire and a true winter tire. A Civic or a Corolla can easily drive in 20 cm of snow (and STOP)with real winter tires. Try driving on packed snow at 90 km/h at -20C with M+S tires and see how secure you feel.

replies: text: The above needs further research and comment. While I agree with the previous editor on his example of usage in serious snow, the definitions, rules or laws regarding "M+S" and "mountain and snowflake" logos/emblems need expansion and clarification. --TGC55 (talk) 02:21, 4 July 2011 (UTC)

message: The brief paragraph on tire width is not helpful. No ordinary reader will have access to the TRA yearbook, even if he can find out what it is. Information or links on allowed wheel widths needs to be included. Lloyd Ewing (talk) 23:05, 29 September 2011 (UTC)
replies: text: Perhaps there should an addition to the article stating the relationship between rim width and tire width.For example: The sticker on my truck indicated that the rim is 7" wide and 16" diameter (has been changed to 17" by a previous owner)and recommends 225/78R16: a width of about 50mm more than the rim.Input from an engineer of tire or automotive company would be helpful.

thread_title:  Tire width 

message: I agree with Lloyd Ewing.
From observation:
it seems that the higher the first 3 digits are, the taller (greater diameter) the tire;
and the lower the next 2 digits, the wider the tire.
This observation is not correct.
From the explanation:
-for instance 265/70R17-
The width is 265mm and the height is 185.5mnm (70% of width) and fits a 17" rim.
The actual height(diameter) 17"+371mm or radius = 8.5"+185.5mm
So... The first 3 digits are the width of the tire and the next 2 digits indicate the height of the sidewall as a percentage of the width ... a very confusing way to indicate tire size. This could also be indicated as 265/185R17.

message: ZR rated tires are mostly for top of the line high performance cars such as Corvettes, Vipers, Mustangs etc. Z meaning it is rated to handle speeds over 140+ mph with a very soft rubber compound for an automobile tire. — Preceding unsigned comment added by 174.138.196.67 (talk) 05:45, 6 January 2013 (UTC)

message: Used apparently to mean either outfitting or fitting. This word does not appear in the dictionary with any logical application to tires or their mounting. It's an old word being used for some new slang. It is not for this article. 73.180.32.63 (talk) 23:18, 15 July 2015 (UTC)

replies: text: Tire code →  – This article is about tire codes for automobiles exclusively. To disambiguate from motorcycle tire code, bicycle tire code, etc. The current article name implies that the article is about tire codes in general. An alternative name to car tire code could be automobile tire code. Sauer202 (talk) 00:22, 24 September 2020 (UTC)

message: Width: 255 mm / 10 in
Diameter: 720 mm / 2 ft 4 in (greater than 200, so represents total diameter)
Max load: 1285 kg / 2833 lbs
Would this be correct? Furthermore, there is no construction code (e.g. R for radial). This tire is specifically designed for an armored vehicle, so could it be using a proprietary construction technique other than radial ply?
