Im considering using 205/50/15 BFG drag radials on my car for the street. Not really worried about tire wear because of the minimal miles i put my car. However, I have heard that you shouldnt leave DRs on a car because it will flat spot the tires or make them get out of balance from the weight sitting on them. Anyone ever experience this problem? I normally drive the car at least once a week... and im wondering if this is enough to keep the tires round. Any thoughts/input is appreciated.
