My car shudders from 50-60 and only from 50-60..... what the HECK is this....im gonna get an alignment but im not entirely sure thats it... any other ideas?

Your tires may be out of balance.

yea the front tires are new and it did it before i put those on.....im gonna check the alignment and i'll post if that fixes it

How about the rear tires?

rear tires are in good shape, but older. i guess they could be out of balance... but the problem is all from the front end, so i dont think that has a lot to do with it. I was reading through the other pages on shudderign, and im gonna do my pcv valve and my wires (already did plugs fuel filter and have newer k&n air filter.)
