if the tread left the tire it might still be drive able to come to a stop but a lot of noise
as seen here
i'm sure if you heard that noise you would be slowing down, notice when the tread separates it does not go flat instantly
a side wall blow out goes flat instantly (i personally seen it happen to a pickup truck at 75MPH) the pickup truck was in the next lane over
normally when i think of the tread leaving the tire I'm thinking of the retreaded 18wheeler tires
i dealt with tread separation Firestone tire (flat hard spot i might be able to dig up a photo) and bridgestone tire
here is a photo of tread separation on my bridgestone tire you can see the tire is warped that is because the tread is coming apart.. |
First, I can tell you don't have access to Tire Guides - the publication that lists all the placard information for all vehicles sold in the US - because if you did, you would have pointed out that Tire Guides lists all versions of Tahoes as listing 35 psi. You seem to be quoting the placard from a single model from memory - and apparently incorrectly. (I'll concede that Tire Guides might be wrong because they don't list any hybrid Tahoes - but that doesn't explain their other information.)
Further a Tahoe is an SUV, not a car.
And I'll cut to the chase: I've examined 1000's of tread separations - it was my job - so I know what they look like - including the infamous Firestone ATX. Tread separations do NOT involve the sidewall.
Take a closer look at the video you provided. The sidewall doesn't fail - the tire is still holding air. All that debris is the tread and the top belt - the sidewall is still intact. (And for technical purposes, the sidewall starts where the tread ends - and that's about 1" from the shoulder point, an area we tire engineers call the buttress.
Sorry, I stand by what I wrote.
