Looks like I'll be putting on the Michelins next time!

If your worried about fuel economy...get tires that are "Green X" or low rolling resistant tires. I have the Bridgestone Duller Alenza plus in 20's and they are an excellent all around all season highway tire...if anything you'll get better mileage over the stock tires. If you are going to haul a lot of weight or do some heavy towing then these probably wont work for you. Check the load range before buying to ensure its what your looking for. I'm usually a Michelin man...but I chose these and I'm happy with them.

When did you put the tires on?
I would bet its the weather not the tires. I have changed same size tire from P-street tires to E range a/t's or more aggressive and never noticed a difference.
