Generally, no. The RE-71R tread wear (UTQG) rating is 200, so its generally considered an extreme high performance summer tire. This is a similar rating to the Nitto NT-05 and Hankook R-S4.
A typical r-comp will have a tread wear rating at or below 100 (for example, the tread wear rating for the r-comp Nitto NT-01 and the Toyo R888 are both 100. The Toyo RR used on Spec Boxster race cars is rated at 40).
These tread wear ratings are somewhat non-uniform so these are not hard and fast rules but they provide some info to help in comparisons between tires.

Depends on how fast you are and what tracks you drive. Faster drivers pull more g's. Stickier tires pull more g's. Tracks with long fast sweeping corners pull more g's for longer periods of time.
