I have a 53 plate Discovery which we have had for 3 years. Ever since we got it, whenever there is wet weather, the back end slides when going round sharp bends or roundabouts, unless, that is, you go at a real snails pace and even then it doesn't feel safe. It doesn't just happen when I drive, my husband has the same thing happen to him. Neither of us are speed merchants, and can't understand why this is happening. We have changed tyres since first acquiring the car and the same thing occurs. Any suggestions as to why this is happening and any solutions? Is this is a common thing?
