I would only use Michelin, Bridgestone, Yokohamas on my Legends and NSX....You will not get good wear out of Goodrich tires, or Goodyear or any of the Korean Crap, but it is possible, depending on the model of the tire to get high performance out of them (but they wear like crazy). Mich MXV4, Bridgestone 930 or 950, or Yokohama Avid Touring (these are freeway tires and will last 80K miles but not H,V, or Z rated...only T so handling is less crisp) depends on what you want...Continental tires are also crappy...very noisy...

first go to www.tirerack.com and look up these tires and others with regard to their performance, actual consumer reviews, costs etc. This is an excellent web site and will help you immensely in deciding on tires and what to expect from them.
I often buy from Discount Tires, but The Tire Rack has a program where they will ship directly to one of the tire stores they deal with and have an installation/balancing cost agreement with them, so you know what it will cost you....tire rack prices are good and the drop shipping is convenient if you don't mind waiting a day or two before getting them installed. The Michelin tires are expensive, about $150 per tire...that is why I went to the Yokohama Avid Touring tire (note the "Touring" designation). They are about 1/2 the cost of the Michelins but last twice as long....but they are not performance tires that you can take to the track! I am now retired so they were great for me..the Michelins last about 40K miles and the Yoko's last about 70-80K miles. good luck. Alignment is only necessary if you have some indication that it is needed, such as tread worn unevenly on the edges of the tires, scalloping (could be balancing that causes that too). My Legends never needed routine alignment, but I maintained the car and didn't hit curbs, changed worn tie rods (this requires an alignment), etc.

I had bought the standard ones, avid touring not the T4. Remember it is a touring tire not a performance tire...also they don't come in a 55 aspect ratio size, only a 60..like a 205x60x16 pr 215x60x16....this will slightly affect your speedo reading by about 3% underreading it....so when your speedo says you are going 70, you are really going about 72 mph. It gives you slightly better mileage too, because the diameter is slightly larger than stock and therefore for every rpm you travel just a bit further than with the 55 aspect ratio tire. So if you were going 80 mph, your rpms might now be 2900 instead of 3100 for the same speed. When your odometer racks up 100 miles you have really gone 103 miles, so don't forget to calculate that in your mileage calculation......

yeah, could be several things that cause vibration....wheels out of balance is most likely (but that will soon be taken care of if you buy new tires), alignment problems can cause this (there will be some evidence in the wear pattern of the tires if there is), a defective tire can cause this (things like tread separation), over or under inflated tires to the point where they become damages, then your next likely cause is the axles and CV joints from the differential.....look at the inner and outer CV boots and see if any is split...if so, you will likely see gobs of grease on inner part of wheel or hear it clicking when you turn corners. Tie rod ends out of steeering rack can wear and cause alignment and vibration problems. This can cause bad wear patterns for toe in and toe out on tires. Go to alignment place that will give you a print out of before and after the alignment with the spec limits printed on the page....any good shop can do this today....and it takes out the guesswork about what needs repair.
