tyre

Attested in the sense “rim of a wheel” since ca. 1500. Generally considered to be a use of Middle English tir(e), a clipped byform of atir (“equipment, furnishings, ornament”), whence modern attire. A less accepted theory derives it from the verb to tie. The spelling tyre was predominant in the 16th century, but largely gave way to tire in the 17th and 18th, before it was revived again outside North America in the 19th century.

     It is also curious that whereas brake-blocks made of certain compositions (other than cast iron) offer improved coefficients of friction, their use can reduce adhesion, and thereby increase the liability to skid (doubtless by tending to polish the tyres) by as much as 20 per cent.
