I know, I'm guessing Ocado have at some time had a bad crash in the ice/snow in an upland area when there was ice/snow either early or late in the season when they were running summer tyres, or that have missed thousands of deliveries during a harsh spellI've tried quite some tires in my life but the Bridgestone LM Blizzak are really great during winter. During summer they're just no good so to me it doesn't make sense they run all year round ??
The incident report blamed switching tyres either too late in autumn; or too early in spring...............or all the KPI where missed and bonuses were cut
and the Senior management response, was "Thats not happening again", just run winters all year, in the scheme of things is not that much money.
I may have a vivid imagination, but I've worked for large companies that make similar types of decissions.
