Talk:Wheel sizing

I suck at making this stuff pretty, but I'm pretty sure the content is good. Feel free to fix this all for me. Note that this wheel sizing is only for Automobiles, I have no idea how other things that use wheels are sized. In fact I haven't put said information into practice, and the diagrams I've created myself based on stuff I've read and heard people talk about, but haven't visited the wheel shop yet, to get new tires for my MGB.. :) —Preceding unsigned comment added by PbS (talk • contribs)

good start
That was a good start. You left out centerbore which is very important when considering aftermarket wheels, and also lug nut consideration. Perhaps wheel offset should be explained in more detail along with back spacing, front spacing, and why offset is critical to keeping the wheel from rubbing the fenders, suspension, brakes, etc. A diagram would be good, considering most people confuse offset with backspacing or front spacing.

will work on it more later, maybe even add a seperate entry for offset —Preceding unsigned comment added by Gambleanderson (talk • contribs)

Disclaimer
What's up with that disclaimer? It's like putting up a big sign saying "this isn't an encyclopedia article". &mdash; Gwalla | Talk 20:07, 16 Jan 2005 (UTC)

Whoever put that disclaimer there was out to lunch. It is definitely a normal technical encyclopedia article, presenting facts, and in no sense "advice, instructions, or how-to content". It is not training (with exercises), or anything else referred to in that link. André437 (talk) 18:58, 22 October 2010 (UTC)

Move Tire Size Information
The section titled "Wheel Size" should be moved to the Tire Size entry. It almost no information concerning wheel size. A link to the Tire Size entry should be placed at the bottom of the page.

Also I would recommend splitting the Lug information into another entry. The Lug entry should also have information about Lug Bolts, Studs, and possibly diagrams of everything.

I'll do this all myself when/if I get the time to figure out the Wikipedia scripting language.

Regarding Wheel size wheels are referred to as 7J or 6.5J where the numbers denote the wheel depth in inches so when fitting a wider tyre it might be advisable to also fit a wider wheel to maintain straight tyre side walls. what does the J stand for and are there any other letters in use? — Preceding unsigned comment added by 89.234.100.17 (talk) 08:32, 2 September 2011 (UTC)

Wheel Load
No mention is made of the required load of the vehicle and the maximum tested load of the wheel. Some consideration should be taken in respect of TUV and also ETRTO guidelines when recommending aftermarket fitments. 219.89.134.59 06:55, 17 June 2007 (UTC) RB

Bolt circle
Here's a formula for finding the radius of a 5-bolt pattern: wouldn't this be easier than trying to draw perpendicular lines? x is the distance between any two adjacent bolts...

$$r = \frac {x} {2 \sin 36^{\circ}} \Rightarrow r \approx \frac {x} {1.176}$$

thread size?
Do all bolts share a standard thread pitch and diameter then? Or do they vary - and if so, is there any way of telling which is which? 193.63.174.11 (talk) 14:55, 21 February 2011 (UTC)


 * Look at this guide for the answer to your question.
 * It has:
 * Vehicle and model, year, bolt pattern,lug size(Thread pitch)
 * lug type(lug or bolt), and center bore of wheel but not size of wheel for some reason. HOWEVER, This seems too good a reference to leave out of the references. I would do it my self but I cannot remember how it is properly done.

 * Lug nut thread diameter and pitch varies, but some are more common than others. M12x1.5 mm and M14x1.5 mm seem to be the two most common on newer cars. This is mentioned in the article now. Sauer202 (talk) 23:58, 23 September 2020 (UTC)

Redirect tire size to article Tire Code
Hey guys... much duplicate information about tires is starting to make its way about wheels... and this also seems to be quite focused on automobiles... — Preceding unsigned comment added by 194.170.14.44 (talk) 08:59, 22 May 2012 (UTC)

Hub centric?
The centerbore section could use some clarification and cleanup, specifically regarding "hub centric". The implication seems to be that the center bore and hub centric rings carry the load of the vehicle. I know this is certainly the perception on internet message boards. However, this is false. The center bore is only used for ease of installation in most cases. The only reference for this section is a company that sells hub centric rings...of course they're going to make wild claims to get you to buy their rings! Here are some better references:

Graphics
More definitive graphics please. Ex. BCD bolt circle diameter or pts B, C, D? — Preceding unsigned comment added by 69.120.118.97 (talk) 19:06, 20 August 2013 (UTC)
 * I agree. This is a perfect place for at least more drawings. - KitchM (talk) 19:54, 4 July 2018 (UTC)

Disc?
The text states "The size of the disc however is denoted like 8.5" X 20.0"." What disc? - KitchM (talk) 19:59, 4 July 2018 (UTC)


 * Probably the brake caliper disc, but there is no reason it also could be stated in metric. Sauer202 (talk) 00:01, 24 September 2020 (UTC)

Staggered
"The other setup option of staggered wheel fitment is having larger diameter wheels in the rear. For example, a vehicle may feature 19 inch wheels in front and 18 inches in the rear." Isn't that backwards? - KitchM (talk) 20:03, 4 July 2018 (UTC)

Needs Cleaning Up
This is a good baseline for wheel sizing and fitment but it needs a lot of cleaning up. Myself and others found it difficult to read and understand. I'd like to go through the whole thing and change up the wording to make it easier to read so a novice is able to understand the topic. I also believe that some more pictures would go a long way in helping this process. A drawing that shows exactly what's happening might be better suited to show than a picture of someone holding a tape measure next to a wheel, for instance. I think that making these changes and adding in some more information will take this article from something juvenile to a reliable source of information for people researching wheels.
