Editing Wheel (section)

===Protruding or covering attachments===
Extreme [[Off-roading|off-road]] conditions have resulted in the invention of several types of wheel cover, which may be constructed as removable attachments or as permanent covers. Wheels like this are no longer necessarily round, or have panels that make the ground-contact area flat.

Examples include:
*[[Snow chains]] - Specially designed chain assemblies that wrap around the tire to provide increased grip, designed for deep snow.<ref>{{Cite web |url=https://search.yahoo.com/search;_ylt=?p=snow+chains |title=Examples of snow chains |access-date=6 December 2020 |archive-date=12 December 2022 |archive-url=https://web.archive.org/web/20221212164743/https://search.yahoo.com/search;_ylt=?p=snow+chains |url-status=live }}</ref>
*[[Dreadnaught wheel]] - A type of permanently attached hinged panels for general extreme off-road use. These are not connected directly to the wheels, but to each other.
*[[Pedrail wheel]] - A system of rails that holds panels that hold the vehicle. These do not necessarily have to be built as a circle (wheel) and are thus also a form of [[Continuous track]].
*A version of the above examples (name unknown to the writer) was commonly used on heavy [[artillery]] during [[World War I]]. Specific examples: [[Cannone da 149/35 A]] and the [[Big Bertha (howitzer)|Big Bertha]]. These were panels that were connected to each other by multiple hinges and could be installed over a contemporary wheel.
*[[Continuous track]] - A system of linked and hinged chains/panels that cover multiple wheels in a way that allows the vehicles mass to be distributed across the space between wheels that are positioned in front of / behind other wheels.
*"Tire totes" - A bag designed to cover a tire to improve traction in deep snow.<ref>{{Cite web |url=https://tires.tirerack.com/tires/Tote |title=Examples of "tire totes" |access-date=6 December 2020 |archive-date=17 May 2022 |archive-url=https://web.archive.org/web/20220517200408/https://tires.tirerack.com/tires/Tote |url-status=live }}</ref><ref>{{Cite web |url=https://shop.tesla.com/product/tire-tote |title=Another example of "tire totes" |access-date=6 December 2020 |archive-date=3 November 2020 |archive-url=https://web.archive.org/web/20201103071434/https://shop.tesla.com/product/tire-tote |url-status=live }}</ref>
Truck and bus wheels may block (stop rotating) under certain circumstances, such as brake system failure. To help detect this, they sometimes feature "wheel rotation indicators": colored strips of plastic attached to the rim and protruding out from it, such that they can be seen by the driver in the [[side-view mirror]]s. These devices were invented and patented in 1998 by a Canadian truck shop owner.<ref>{{Cite news |title=Here Is What Those Strips Hanging Off Of Truck Wheels Are For |url=https://jalopnik.com/here-is-what-those-strips-hanging-off-of-truck-wheels-a-1848314282 |access-date=2022-01-07 |website=Jalopnik |language=en-us |archive-date=7 January 2022 |archive-url=https://web.archive.org/web/20220107161233/https://jalopnik.com/here-is-what-those-strips-hanging-off-of-truck-wheels-a-1848314282 |url-status=live }}</ref>
