It jiggles around like mad, it feels as though the wheels and tyres themselves are very heavy / made out of lead. I also feel this in the steering being heavy. I have tryed all tyre pressures from 38PSI to 26PSI with only slight improvement at lower pressure levels. My last 2 cars had mag wheels and felt alot lighter in the steering and suspension also. The car is running std steel rims and dunlop sports 300 tyres.
