quieter tires (with same or better MPG)?

[toymhe]

I'd like to replace my original-equipment all season Bridgestone Turanza EL400 V-rated tires with quieter tires that offer the same or better MPG.

A TireRack salesperson recommended sticking with the two original equipment choices (the Bridgestone EL400 and the Michelin Energy MXV4 S8) -- on the basis that Toyota chose them to maximize the EPA mileage values.

According to the TireRack surveys, the MXV4 S8 is quieter than the Bridgestones -- but the surveys also list several even quieter tires. Unfortunately, the surveys say nothing about rolling resistance -- thus the quietest tires may yield lower MPG. Consumer Reports provide rolling resistance info, but they test only a small set of what's available.

My priorities are low noise, high MPG, and decent performance in rain -- I almost never drive in snow or ice.

Comments and suggestions will be appreciated.

Michelin MXV4 S8..quiet and LRR. Best combination imo. (We had the MXV4 Plus.. one level below the S8).

mxv4 is a very good tire. Salesman said it actually moves through water better than the rain tire. Very good in snow as well when compared to a Dunlop. I have had them on my last three cars.
