I purchased a car in May. The initial drive home on smooth motorways was okay but the day after I realised the car was very bumpy and erratic on urban roads and potholes etc. On inspection, I found an amazing 46PSI in each tyre. I deflated them to manufacturer spec and it seemed a little better obviously. I decided to give my self time to adjust to a new car as the tread was good on the tyres and a leading brand. However, the tyres just seemed noisy.

A few weeks later I had to travel about 40 miles and the car was so erratic with the steering wheel vibrating over 50mph and I did not feel in control. I decided to go into a tyre company to have them inspected. All four tyres were out of shape due to over inflation and the tread was stepping. They removed all four wheels and attempted to balance the tyres but it was impossible due to their condition. I purchased the same spec tyres at great cost and the car now drives like a dream. The tyre company gave me a printed report on the condition of the tyres and I have them in storage as evidence. The seller says because the tread is okay the tyres are okay. The dealer refuses to have anything to do with me regarding paying for the tyres and have bombarded me with fake emails and correspondence to my home from a fictional law advisor stating they are not responsible in any way. Any advice would be greatly appreciated.
