My previous set of Toyo's were the M-144. I got five years of service out of them with no problems as far as to blow outs or tire wear. But when I changed them out at five years I did notice side wall checking was starting. I replaced them with Toyo's M-154 and these have been excellent tires.
They both gave smooth riding, even tread wear which was not much at five years. Fact the tread still looked new.
Toyo tires are very good tires, rated H, 16PR. My tires 22.5
