I put these on and see they are showing these cracks. Is that normal? Both mains have the same small cracks running along the centers. They are about a year old and I ordered them from Spruce.
When it happened to me, tire pressure to low. Desser says 40 PSI plus and you won't get these cuts. I did that and I haven't had any since. I know the PSI is higher than Van's says but if you don't get a shimmy more is better. I run 45 in my RV6A all the time. It works for me.
