Prior to 1964, tires were all made to a 90% aspect ratio. Tire size was specified as the tire width in inches and the diameter in inches – for example, 6.50-15. [24] From 1965 to the early 1970s, tires were made to an 80% aspect ratio. Tire size was again specified by width in inches and diameter in inches.
A spare tire mounted at the rear of a Mitsubishi Type 73 Light Truck as an example of a repairable spare part. In logistics, spare parts can be broadly classified into two groups, repairables and consumables. Economically, there is a tradeoff between the cost of ordering a replacement part and the cost of repairing a failed part. When the cost ...
Spare tires (sometimes called "doughnuts") for modern cars are smaller than regular tires (to save trunk space, weight and cost) and should not be used to drive very far before replacement with a full-size tire. A few vehicle models use conventional size spare tires. Jacks and lug wrenches for emergency replacement of a flat tire with a spare ...

Tire load sensitivity describes the behaviour of tires under load. Conventional pneumatic tires do not behave as classical friction theory would suggest. The load sensitivity of most real tires in their typical operating range is such that the coefficient of friction decreases as the vertical load, Fz, increases.
