New Michelin tires about a year ago. New brakes early Aug. 2011
Late August 2011 road trip, in the rain, a noise at interstate speed happened, on and off, and sounded exactly like a tire going down. Sort of a "roaring" noise.
Pulled off interstate, checked tire pressure.30 psi in all tires. Upped it to 35 psi. Continued trip, ran out of rain, and no more noise on that trip of several hundred miles. Return trip with no rain. No noise.
Mid October 2011, interstate trip of 700 miles. During trip ran into rain, and the identical noise happened again. Several times. On and off. Pulled off, checked tires. Pressure 35 psi. After several more miles ran out of the rain, no more noise. Have driven a couple of hundred miles since, in dry weather. No noise. I will be returning home 700 miles next week.
Any ideas of what could be causing this noise.I have had tires go flat before, and this noise sounds just like a tire going down, but only lasts a short time. Goes away, then re-occurs. But ONLY DURING SUBSTANTIAL RAIN. Never had it on dry pavement?
