Guys,I am going to replace my tires. I did not like the Yokohama AVS dB. They perform fine, but they have severly feathered and are noisy as the result. I don't mind spending the extra money. What is the best non-directional tire in 225/60-15 size out there. They have to be quiet and do good in rain.

There's the rub: quiet and good wet traction don't go together because wet traction means soft fast wearing rubber compound.
Michelin Pilot H4 will be the quietest but the 400 tradwear is undesirable for better than average wet weather. They stay pretty soft for the first year or 15,000 miles
The Firestone Sz50 EP are quiet and excellant in wet but directional and not useful below 32F.......but will be soft for 20,000 miles or 18 months.
The sipes when feathered are what make most of the noise on the DB.
90% of hydroplanning [assuming at least half tread] is from underinflated tires [not running 35-36 psi] not the tread pattern......the rain cools the tires and the pressure drops!

I looked at the previews on Firestone Firehawk SZ50 EP on Tirerack web site. The previews were almost perfect. Had a set of them installed today. Three of them took half an ounce(less than 15 grams) and one got 1 ounce of weight to balance. I did not have a chance to take it down the freeway to test for noise.
Firestone has a 30 days test drive program on their high performance tires with full refund in case of dissatisfaction. Hopefully the tires will measure up to what they are prescribed and I will not be disappointed.

Scares me when shops use ounce denominations as they might just be leaving the balancer on coarse [round to nearest quarter ounce or 7 grams]........................I want to see 1,2 gram errors.
28 grams or 1 ounce should be suspect have the tire /wheel checked on a Hunter 9700 machine and match mounted [tire rotated on wheel] to minimize radial force imbalance down to 5 pounds at 70 mph.
