Those Michelin's are old (XZE), not even XZE II's.
The front michelin steer tires didn't have any sign of fracturing - but i didn't check the dates on any of 'em either.

I've got Michelin in the Steer Position and haven't seen any problems - on the other hand the Good Years that were replaced had vertical fracturing on 'em.....the Good Years on the rear/drive were 8 years old and had no sign of fracturing.

I use 303 Aero Protectant on all my tires
