Zero wear.
At 2-7/8" we ran them up to 13,000 RPM with no problems, though our normal operating speed was around 10,500 rpm. That works out to almost 10,000 surface feet per minute. The same surface speed for the 4" wheel would be roughly 9000 RPM, though it's going to expand more and give you a higher effective surface speed.
I know 233 accidentally ran a 4" one up to 13,000 and it exploded nearly immediately.
