Very good recent article about comfy cars, which has prompted me to seek your advice. I recently purchased an X-Type Jag that has 17-inch alloy wheels, fitted with Michelin 225/45ZR17 Pilot Sport tyres and I am very disappointed with the noisy and harsh ride over potholes and bumps. My previous car, a Mondeo, had 16-inch wheels that rode OK and I am surprised that going up an inch has made all that difference. Would changing the make/design of tyre improve the ride at all? If not I assume the answer is to fit 16-inch wheels. If so, will Mondeo wheels fit the X-Type?
