I wouldn't ride the Iron Cross rims at 70 psi, but it was safe enough for mounting. YMMV
Thanks! I had not thought about/considered this due to the recommended max pressure being 45 for the rims. However, this may be something to try to see if it will correct the "problem". Once you had them seated did you lower the pressures back down and everything still looked good?
