Introduction to Tire Engineering
Published in Brendan Rodgers, Tire Engineering, 2020
There would also be sub-categories for each tire type, depending on the mission profile. For example, there are several types of automobile tires, such as high-mileage, all-season, base-line and broad-market tires, traction, and high-performance tires. Each type of tire will have a specific type of tread pattern and tread compound, designed to meet the design targets. Though there are many exceptions, Table 1.3and Figure 2.11 provide a general summary of the type of tread pattern to be initially selected when designing a new tire for a given mission profile, such as a base-line, high-performance, or high-mileage passenger tire.
Selection, maintenance, and relations of various parameters for off-highway hauling tires

Tire storage should ensure that the tires are kept away form dirt, moisture, oil, grease, and gasoline. The rims should also be watched for damage. A bent-out flange will allow tire beads to distort. Dual tires must be well matched. Tires should not be mounted side by side in a dual set up if their overall diameter varies by more than 1/4" to 1/2". Bad matches will create an overload on one tire and destructive scuffing on the other. Each pair must also be at exactly the same inflation pressure. Proper spacing allows air to flow smoothly between the tires and resist heat build up.
Tyres, road wheels and hubs

To extend the life of tyres it is important that their relative positions on the vehicle be changed or, as it is commonly termed, ‘rotated’ on a regular basis, typically every 6000 miles (10000 km). This is necessary to even out the tread wear between the front and rear tyres, because of the different duties they perform according to vehicle design and the further influence of driving style. The particular vehicle manufacturer’s recommended rotation intervals and sequence must therefore be followed.

A Monte Carlo simulation was performed to generate random data using a normal distribution with mean and standard deviation values for each vehicle characteristic. For tire tread depth, 5.5 mm (7/32 in.) was selected as the mean value and 1.9 mm (2.4/32 in.) was selected as the standard deviation. Typical new tires have approximately 8.7 mm (11/32 in.) tread depth and 1.6 mm (2/32 in.) tread depth is typically considered the legal limit of tire wear (Tirerack, 2017a). For tire pressure, a mean value of 241 kPa (35 psi) and a standard deviation of 48 kPa (7 psi) were used. Typical passenger vehicle tire pressure ranges from 207 kPa (30 psi) to 241 kPa (35 psi) (Tirerack, 2017b). To account for the larger-size vehicle use in the region of the case study, a mean vehicle weight of 19,500 N (4400 lb.) was used, with a standard deviation of 4250 N (950 lb.).

Another factor related to the force transmissibility is the tire pressure. Tire pressure is defined during development considering three factors: dynamic comfort, tire wear and fuel consumption. Tire pressure values may range from 28 to 40 Psi depending on vehicle class.Rear suspension torsional stiffness

The steel rotating arm of the testing platform has an adjustable length to accommodate different sizes of test tires. The length of the rotating arm can be varied from 5,124–4,684 mm. The radius of test tire that can be tested covers a range of 230–450 mm. The maximum load that can be applied to each test tire is 5.0 kN. When loaded with test tires, the rotating arm takes about 65 s to reach the design speed of 70 km/h.
