It all depends on the road surface for your dailing driving .
With 21s you have little rubber left and every pothole/large bump (bridge overpasses etc) is a potential
hazard to have your wheel bent or worse.
I was also very tempted but decided against 21s as driving in downtown Boston(ia) is bad enough on 20s
