I just put on my first set of replacement tires. The recommended tire pressure for the factory tires (Battlewings) was 36 psi front and 42 psi rear. However, the maximum recommended pressure for the new rear is also 42 psi. Is it OK to run it at maximum or is there a way better way? How do I determine the optimum or recommended pressure setting for the new style tire (TKC70)? I don't want to run a few thousand miles over inflated...
