If the only change you made was the tires then you need to suspect
that before anything else. Probably just need to balance. Did you
change rims too? If so, suspect them also.

I would tend to agree with this but the tire size change would also have
changed his cruising speed driveshaft rotational velocity. This could have
exacerbated any pre-existing driveline alignment problem. It does sound
like a front tire slightly out of balance. A quick and dirty diagnostic is
to rotate the tires. If the noise goes away then back to the tire shop to
get them all balanced.

Mike, I know how infuriating SnoTool is, but do us all a favor and ignore
