During a donut - which tyre wears quickest?

[FreeLitres]

If you were to do a donut in a RWD car in a clockwise direction, which of your rear tyres would wear the quickest?

The outer/leading rear or the following/inner rear? Or would they both wear at the same rate?

Outer one

From lots of practical experience

Depends on the slip of the limited slippy diff?

Do you mean the leading one?

My rear drivers-side tyre has more tread on - Should I donut anti-clockwise to scrub it down?

(About to swap my tyres anyway but want to get some fun out of them! - strictly on a private road though)

Outer leading rear definitely. It's carrying the most weight whilst spinning. Based upon my autotesting experience.

Cheers guys.

I expected the outer one to be under more load, but thought the inner one might be spinning a bit faster (limited somewhat by the diff) but I go with what you are all saying.
