Tires are like oil...everyone has their preference. Personally I like the Continental ExtremeContact DWS's, but recently mounted on a set of General G-Max AS03's as I was on a tighter budget this time around. I've only had the General's on for a few days but so far I have no complaints.
Input your tire size(s) on tirerack's website and check reviews for tires in your budget.
If you need an opinion, I like the Michelin energy savers on my 17" wheels. Can't comment on how they ride compared to other tires, but they're great in the snow and are quiet. They're also low rolling resistance to maximize mpg and last longer.
There is no BEST tire for YOUR car - everyone's opinions and preferences are different and you'll get pro, con, and indifferent opinions on every tire made due to different locations, weather conditions, driving habits, blah, blah, blah.
Get into www.tirerack.com and compare tires in your correct performance rating (driver's door sticker) and size. Read the customer reviews on each. Make a decision. I tell you that FlapRound tires are the best thing since sliced bread, you buy them and aren't happy - I look like a fool.
P.S. - You do not need tires with a higher speed rating than the originals on the car - the door sticker. As speed ratings go to H, V, and Z/W the pricing becomes astronomical.
Be careful with the Generals, I am a General Tire man, from WAY WAY back, My Stepdad,
drove big rigs, and he swore by Generals, So I did too.
I had Generals, on my 05 STS, and totaled it, because of loss of friction, So be careful
on WET pavement.One pair on the 05 was less than 6 months old.
I have the Michelins, Didn't want them, but hard to find, traction AA and wear 500 or more.
BUt the harder the tire, >500 usually means poorer traction. and Temp A. So AA 500 A
These Michelins Ride HARD, so next time I am NOT getting Michelins again.
But "MY" specs may preclude that. AA >500 A.
With the MRC's it may "not" give me a better ride.
So far the Michelins have been trouble free.
Road noise I think is normal.
Got mine at Tire Rack
My wife's STS was equipped with Michelin Energy from the factory. They are good for mileage, but slick & dangerous on wet pavement with less than 20,000 miles wear. IMHO, Michelin now sacrifices too much in terms of quiet, ride & performance for durability & mileage all across their product line. I'm now a Conti fan.
I put on a set of Kumho Exta 4X from Discounttiredirect because they were on sale and the reviews were decent. UTOG is 420, traction AA and W rated. So far very sticky in all weather and super quiet. I only expect to get around 30-35K out of them but hey, I only paid $100 each inc shipping.
I have the DWS. Little bit harder compound and different pattern for longer life. I see your in WA. If you experience snow I would opt for the DWS. The DWS pattern will operate better in snow. If not the DW would be extra sticky but would wear out quickly.
DWS has the better tire warranty. After you purchase tire, have them Road Forced Balanced, makes ALL the difference in the world. Also have the tech center the tire on the rim for the best balance. All done on the Hunter road force balanced unit.
