Lingering problem. Whats next?

First I would check that the wheels are correctly mounted. If you are using a centering ring make sure it is the correct one and correctly fitted.

2nd would be make sure that the wheels are correctly balanced. Have them checked/re-balanced on a good road-force balancing machine.

Worst case, bent wheel. You can check for this by jacking the front of the car up and spinning the wheel slowly by hand while holding a reference next to it and making sure the lip is even all the way around. Your balance shop should be able to tell you that it is likely bent if you end up with a crap load of weight on one side.

Check to see if you have a broken belt in a tire.

that or even a slit in the sidewall or tread, or even a bubble.

should take the wheels off the car and inspect.

How many mikes are on the car.. I ask because our cars have seal hubs. Sometimes the hub where's out and will cause vibration at cretin speeds. That is an indicator of that issue.

Some thing to check:
-M130's are already hub centric but ck the lug nuts
-Take a large screw driver or a crow bar and jam it under the tire then lift it up and down. If you here a popping sound then one of your ball joints is warn out. Most of the time its the lower one.
-If you feel the popping in the hub then its the hub.

You can tell were the problem is by the sound and putting your hand on the joints when you lift up.

Hope this helps
