Since I have to classify it as a risk whether the 185 tires have enough space on my 4/4 or not...and because I haven't found anyone in Cologne who can certify my speedometer for the MOT, I ordered the tried and tested 165/80 T-Trac 2 again. Of course I can adapt the Morgan speedometer myself to the smaller tyre circumference of a 185/65, but it has to be officially certified. You can change a few things on your car that are not quite legal but are not immediately noticeable. For example, my exhaust manifold with metal cat, which is further away from the engine exhaust than the standard cat. But the fun stops with the tires. In the event of an accident, the tires are always the first thing the police and insurance companies look at, which must be absolutely correct. No MOT without certification of the speedometer, so no go. I could have had it done if I really wanted to, e.g. in Stuttgart for €300. But that's too much effort for me. Now I'm looking forward to new T-Trac 2, my third set for this car with 120,000 km in 10 years. Many thanks for all the replies.
