Mounted front and rear at the same time. Have almost never done that before. Rode as if the tires were flat even with 42 PSI cold front and rear.
Shinko makes a Verge and a Verge 2x. The 016 is 2x which may mean soft rubber sides hard center. Sad I disliked these as Shinko makes some exceptional off-road tires.
I'm good about logging mileage but lax in recording the price paid for tires. IIRC the 016 Verge 2x tires cost more than the closeout T30 Evos I currently have mounted. Wore twice as fast as the T30 Evo GTs I have used previously. On my friend's FJR have not noticed difference in wear life of PR4 vs PR4GT so I'm not expecting any difference with my T30 Evo not-GT.
