Wobble

[TjXiong]

So I bought a new set of tires from Discount Tire a few months ago and I noticed that there was a fish like wobbling movement as I drive the car on concrete pavement (those that has small line,texture going across the concrete). The car will feel and drive as its moving from the left to the right just how a fish would be swimming.

Than when I go and drive on black asphalt pavement road it will drive with no wobbling; smooth as a Cadillac. I checked my suspension, took it to Tire Plus to get it check out incase I missed anything, took it to a friend brother auto shop to also get it check out and got it checked at Mitsubishi with no suspension problem.

The last thing that I can think of is the tires; BF Goodrich G-Force Super Sport A/S. I had these balanced 3-4 times and one tech said that these tires are known to wear out on the shoulder first before the middle section wears out. Now I noticed that that is the case leading me to think the car feels like crap; all soft and wobbly. My car is lowered with Eibach Pro-kit springs; 97 GST Spyder. Any thoughts? Thanks guys/gals.

Go to a shop that has a road force balancer.

Thats not correct. If a car is correctly aligned and tire pressures are set for the car, a tire should wear normally.

Couple of thoughts;
- Concrete roads with the lines always tend to cause cars to ride them. That is fairly typical.
- As dsmghost said, go to a shop where they can road force balance the tires. You may have a tire with excessive road force, or one that has some minor tread separation.

What speed is the wobble more present at?
