0.05" is less than 1/16" and most cannot see that ...I can't
The dots are easily rubbed off...some less so than others.
If they have the same tires in the showroom, check if they
have the dots... I'm suspicious...
All high speed rated has them...even my Bridgestone "LT's"
On pricing...higher speed rated & lower profile cost much more.
Am restoring my 2 seater and will have V or Z rated 40 series.
Should be in the +$900/ea range. Ditto higher load rated LT
class on my Sub at $250/ea...better usually cost more
Personally not sold on that extra width groove being able to make
up for depth and channel enough to prevent hydroplaning
Not just while moving, but most critical during braking and
cornering
Think yet another nail in Michelin for me
