a couple interesting trucks in the Iowa 80 Trucking Museum
This is an Avery truck. The Avery Company of Peoria, IL offered their wood plug tire sometime around 1910 and it consisted of a hard rubber tire with holes around the perimeter mounted on a cast steel rim with 96 hard wood plugs driven into the holes. When the plugs wore down, the whole tire wasn’t replaced, just the plugs. Worked great on dirt roads.

Firestone has been on the winning Indy 500 car more than all other tire makers combined, 67 of the 100 races.

Porsche, Ferrari and McLaren agree on one thing for certain... the Pirelli P Zero is their choice of tire. It just turned 30 years old
The company’s “Perfect Fit” strategy means each one of its 60 homologations have been customized for a particular car. If the 911 Turbo needs more squared shoulders for better cornering, Pirelli will do that. If the next Lamborghini needs extra clearance, it can round the shoulders. All 305/35R20s are not created equal.
For the 30th anniversary, the P Zero was updated, slightly.
The footprint is now flatter, which leads to a longer life, says Pirelli, while more tread pattern grooves and wider and deeper channels help wet grip. Pirelli also changed the way the transverse grooves line up, meaning less road noise. Rolling resistance was cut as well, through the use of new modeling techniques and more silica content in the rubber. That should be good for an mpg or two.
The latest tech from Pirelli, though, is its new noise cancelling system. The guts of the tire are filled with a layer of polyurethane sponge that dampens both the noise and vibration transmitted to the cabin. Pirelli says the new P Zeros are 2-3 decibels quieter, which is equivalent to cutting noise in half.
