Afternoon fullas.
The snow and ice driving tips are awesome. I hope i never need em.
I worked for Bridgestone Firestone for 14 years in various retail roles before going to boil oil. Tire stuff is cool.
We use old tractors, David Brown 990s, Ford 3000s etc to launch boats here a lot. Soft sand and the chevron (V) pattern tires don't go together. The point of the V splits the sand away looking for hard stuff underneath, of which there isn't any of course. But, swap the rim and tire to the other side so it's facing 'backwards' and the sand gets collected by the open side of the V and compacted as it goes toward the centre. Result, major drive and no diggy downy.
Dirtbike tire manufacturers cant agree either. Michelin, no mugs by any stretch, demand high pressures around 15psi to keep the knob in shape to drive it in to the ground. Other manufacturers taking opposite tack and making tires that can be effective at 4-6psi effectively making a short 'track' as the tyre passes over the ground.
More than one way to skin a cat is my point.
