Grrr.... new tires installed, still vibration.

[Subix]

I'm discouraged. Mainly because I just shelled out nearly $500 to have these tires put on and yet I still feel a minor annoying vibration around 60mph.

So, it's probably my fault for being (or trying to be) a cheap SOB and taking it to Wal*Mart to save $25 for mounting/balance/installation. (I'm sure the word Wal*Mart makes people cringe). I suppose that's what I get

Do you think the techs at Wall-E World just didn't balance them right or enough? Maybe I have a front wheel bearing going out (which I don't think because I would think I would hear humming from the front (( or do those not hum? )) and the tech at wal*mart probably would have noticed wiggling while changing the tires, right?)

Could alignment have anything to do with the vibrations at those speeds (not from my understanding). On some roads it seems to go just straight... others slightly to the left so I'm unsure if it's just the road or alignment.

I'll most likely have to take it to Car-X or something in the morning and have *professionals look at it (aka, spend like another $80) and give me their opinion... if it is balance related, I doubt Wal*Mart will do any better the 2nd time around...

What do you guys think? (besides my ignorant choice in going to walmart, apparently...)
