The wear on the inside edge may be due to incorrect air pressure. Resulting in the tyre being worn out on the inside edge.
I own a Mondeo too.
These cars go around the corner like on rail. We do not realize how fast we go. With other cars would be some noise or unbalance.
The strain on the tire while cornering I think is higher compared with other cars. Take this in account.
I have a 1800 Zetec. This being the first Ford I have owned I was very impressed. I can't follow on your comments on tyres though, I have already done 11000 miles with no real indication of front tyre wear. I know you may be shouting just another Sunday driver, but believe me I'm not. The only criticism I have of the car is it seems to be a little short on engine performance as compared to my previous 1.8 Vectra. I don't know if this is something I need to address or whether I'm just expecting a little too much.
My Y Plate Mondeo has just completed 72,000 miles. I'm really pleased with it, except the air conditioning has just broken. The cause is that one of the air conditioning pipes passes through the off side inner wing and rubs on the metal causing it to burst. When I took it to my local garage they had two more Mondeo's in that month of the same age with the same problem. Suggests to me it's a small design fault that needs to be rectified.
The tyres may be expensive, but those cosworth alloys on the 99-00 Zetecs are a work of art.
