Had a riken raptor 225/55r16 rear tire. Got 20000 miles on it. Rubber started cracking around the edges so decided to replace it with a bf goodrich 205/60/r16. The riken was always problematic in that the width made it difficult on rough terrain. It would also do a lot of hunting for a line to follow. This new tire is the same circumference as the riken.but handles much better.
