Ford Fiesta MK8 Ecoboost (100hp) Tires

I have the OE version of the tire for BMW, which is a AAA version in 215/45 17. They were mounted on the rear axle of a Ford Fiesta ST Line 155 MH for testing.
Continental Premium Contact 6 tires are used up front.
The MAXXIS tires are very quiet, precise, and light. I'm convinced they're absolutely on par with the Continentals, as my car zips around fast corners with absolute neutrality and remains neutral with every load change.

Reasonable tires for the price, down to around 25k miles before near wear mark. Nothing exceptional about them but I've had more expensive tires with poorer grip and much worse wear.

Bought the car in 2020 with roughly 9000 miles on the clock. The tires were in good condition at the time. Grip was decent and wear was low around the centre of the tire. Did notice the sides of the tires wearing faster though. Wheel alignment was done but did not change wear patterns. Decent in the wet but will start to slip if you are excessive on the throttle in turns. Did not spin much in a straight line in the wet back then. After 2 years and 9 000 miles, the tires started to go south. Lots of understeer and sudden loss of grip in medium to tight turns. Excessive wheelspin if I apply more than a quarter throttle on most roads at pull away. (With traction control activated there is still wheelspin) The tires feel very hard and dry although they still look good and have a lot of tread left. Braking feel is very numb right now, there is no feel or the car doesn't slow down much until about halfway down the pedal travel. (brake discs and pads are still in good condition so it can only be the tires) I need to replace them soon as they do not give much confidence when pulling away, braking or turning in general.
