I have never owned the MXV4. I had some Michelin Sentry tires, supposedly the entry tire of Michelin and they were junk. I upgraded to the Michelin Destiny and find them to be far superior in wear, handling and ride. The Sentry tires were rated at 65,000 and I never got more than 12,000 miles on two sets. The Destiny tire is by far a superior product.
