I run my D404's stock size at 34 front and 41 rear, the Dunlop recommended loaded pressure, cause I'm 260. I've noticed that my front tire is ready to be replaced with 8200 miles on it. My rear only has about 4000 on it and it looks just as worn in the center and needs replacing already. Sides still look new on both tires really. I ride every day barring rainy weather and mostly rural mainly straight-slight curvy roads, not much twistie riding. Does this sound normal? On a car or truck, this wear pattern would suggest overinflating, but the rounded motorcycle tires seems like would normally wear mostly in the middle. You think I'm putting too much emphasis on my weight and maybe should be running slightly lower pressures? Seems like short tire life to me! Any thoughts?
