Sorry, thought that i ride along a bit ...but your correction of my post made you look a bit smartarse in my eyes so i thought i can do it also. I apologize for my complete lack of english awareness.
Doughnut and donut are the same actually.
"The first known printed use of donut was in Peck's Bad Boy and his Pa by George W. Peck, published in 1900"
So according to the Oxford Dictionary while "doughnut" is used internationally, the spelling "donut" is American...
Actually you also misunderstood the question here. On his case there can't be a single answer. The tyrewear depends on speed, route and the amount of time he is spending on cooking while driving. Usually making donuts does not affect tyres since people tend to cook them at kitchen.
