I bought 51mm tablets like 2 months ago when I had my Thunders but only rode them for like an hour. I put my Indy's back on with my old ass 54mm conical full's but since going down to 8.38 the other day I feel like the truck is too crowded and I can't get on coping that easy. Even 50-50-s feel hard to sit on, I have to ollie out earlier than I want to. Put the tablets back on today, but I did it after skating all morning so I'm too tired to see how it feels. Tomorrow though.
