Yes, merge. (or possibly delete the other page) I started the other one because I can spell tyre properly ;-) this one needs an English spelling reference too MikesPlant 14:46, 17 April 2006 (UTC)
Can anyone tell me what a 155/SR13 tire is? No one around where I live has heard of one. My 88 Corolla needs a set of front tires and 155/SR13 is the stock sizing. Would a 155/80-13 work? 156.34.156.212 21:34, 27 October 2006 (UTC)

What are "special trailer" tires? --Una Smith 02:09, 4 November 2007 (UTC)
They are... special tires for trailers!
Seriously, they are typically bias ply tires with stiffer sidewalls to reduce sway. They're often more expensive but tougher than passenger or light truck tires, since trailers usually don't have the sophisticated suspension systems used on cars or trucks. Captain Packrat (talk) 18:59, 2 January 2008 (UTC)
Is there an explanation of tractor tire sizes anywhere? They are normally in the format 14.9-24 or 6.50-16
I suppose the second number is the size of the rim. but I don't know what the first number represents.
I'm trying to find options for the front wheels on my tractor, the current tires just don't work for me. They are a 3 rib design, and the problem is, they dig into the ground too much, and I get stuck very easy, especially with anything in my loader. I notice that cars, trucks, and my van... even cement trucks never get stuck, and they all have wider, flat tires, so I'm thinking if I can get a wider car or truck tire to fit on my tractor rims, I would have more surface area to hold up my tractor and it wouldn't dig the front wheels in so much. The tires on there are 6.50 - 16 but they could be a bit wider. If I could understand the size I have, maybe I could find something else that would work.

The general "tire size" topic would not be complete without mentioning pre-"P-metric" sizes. Take a look at [1] if you're wondering what I'm talking about.69.210.14.71 (talk) 19:12, 6 February 2008 (UTC)
On all the tyres I have seen in the UK they don't have a vehicle class digit. Mabey someone might consider that in making this artical more worldwide. --Siripswich (talk) 18:38, 16 April 2008 (UTC)
A redirect Tire identification number (TIN) points here, but is not explained. +mt 01:06, 26 May 2009 (UTC)
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)
I do know it is mandatory in Germany, had a rental car with just such a sticker. I'll edit the article to say "many." --Drmemory (talk) 10:33, 19 July 2011 (UTC)
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.

--Sluchino (talk) 22:35, 7 April 2010 (UTC) I have a question, if anyone can give me an answer: How important for the car a number of speed matter for exmpl. V93 or H91. Is it only speed matter or it can affect the parts of the car if you use the wrong number (manufacturing number). And if anybody has answer can I have a resource of the information?
If you are still alive ;-) the letter is the speed code -- the number is the load rating. You had best not use tires of a lower load rating unless you look up the max load in pounds for your current tire at current PSI, and see what PSI is needed for the lower load rating tire to carry the same load. You likely have to raise the PSI. This is a tricky business as you are affecting handling.--Drmemory (talk) 10:30, 19 July 2011 (UTC)
I agree with Steve Baker. Consolidation of this information would be helpful. —Preceding unsigned comment added by 12.238.232.226 (talk) 20:43, 3 January 2011 (UTC)
The UTQG is being phased out and will be gone shortly, I am told by Bridgestone.--Drmemory (talk) 10:17, 19 July 2011 (UTC)
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.

Although there is no question that the Mountain Snowflake Pictograph marked tires are better, the M+S marking is legal in some jurisdictions in Canada — ref:https://www2.gov.bc.ca/gov/content/transportation/driving-and-cycling/traveller-information/seasonal/winter-driving/about-winter-tires No winter tire laws exist in AB, SK or MB — I didn't check elsewhere MagisterVorpal (talk) 19:31, 27 December 2021 (UTC)
M+S is mud plus snow, and they are better than non-M+S tires in the mud or snow. They have a self-clearing tread that doesn't pack.
But the others are correct in the Mountain plus snowflake tire is a different animal. They are called "hi traction" tires and are required when many rocky mountain states require the use of chains or high-traction tires for some mountain passes. These are what used to be called "snow tires" when I was a kid in New Jersey. Big old noisy tread, not some slight M+S modification.
All of these are not to be confused with "studless studded tires" such as the Blizzak. This is a tire that performs like a studded tire on glare ice, but has no studs. It is just an M+S tire when it comes to snow. --Drmemory (talk) 10:25, 19 July 2011 (UTC)
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)
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.

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)
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)

Tire code → Car 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)

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?
