I just got new tires on my blades, when i drive on the parkway i hear a little humming sound now i wanted to know if thats because i need a whell alignment.

 

Tire hum is a direct result of tread design. If they are ultra-high performance tires, then chances are they will be quite loud. Usually some NVH (noise & vibration harnshess) supression is sacrafised to make the tires perform better. The suckie thing is that the noise usually gets worse as the tires wear.

What tires are they?

You should be able to look up buyer reviews on http://www.TireRack.com & see what other people say about those particular tires...

I have had those tyres on a few cars, now. They're are an extraordinary buy and give you a lot of grip for the money, and in lots of weather conditions...but they do hum, and it only gets worse with time.

 

It looks like I have toget used to the sound or turn up my radio a litle more.
