I have been running Nitto NT-01s all year and these will be my 4th set.
In case anyone wants to try a set (maybe DE or enduro tire), discounttiredirect.com has $50 off on set of 4 tires for NT-01s today.
205/50-15 delivered to your door for $494.00
I have not tried R-888s so I couldn’t give you a comparison but I think they are similar.
