I was checking tire depth with the Lincoln head technique (if tread covers Lincoln head, you are good with the 2/32), I noticed tires were getting close and maybe had 1/32 extra. Maybe enough for Summer?
Googled tire depth and learned there is considerable stopping and safety advantage to use WA head quarter as the standard for replacement. Quarter provides 4/32 depth vs the penny's 2/32.

"This time the repeated runs taught us that the average stopping distance for the legal 2/32-inch deep tires from 70 mph was a staggering 499.5-feet in 7.5 excruciating seconds."....
"The runs indicated that the average stopping distance for the 4/32-inch deep worn tires was 377.8-feet in 6.0 seconds.
Costco has a tire sales with $70 off Michelin plus $60 more if you use their CITI credit card--with a bit reaction time loss at70+, guess I am buying tires this weekend.
