Basics of Tyres & Rims (Vehicle Dynamics)

Explore how tyres affect vehicle dynamics, including section height and rim diameter. Learn aquaplaning, tread wear indicators, radial versus cross-ply tyres, tyre inflation, wheel offset, and slip angle.

Explore tyre sidewall notations such as width, aspect ratio, load index, and speed rating, and how profile affects comfort and handling. Compare high and low profile tyres and trade-offs.

Aquaplaning happens when a tire cannot remove water quickly enough, reducing friction and control; grooved tires push water out and tread wear indicators warn when replacement is needed.

Explore cross-ply versus radial tires, including bead shapes, tubeless design, rolling resistance, fuel economy, load-carrying capacity, and handling differences essential for vehicle dynamics.

Explore how tire inflation affects the contact patch, wear, fuel efficiency, handling, and stopping distance, and learn to maintain correct pressures for optimal vehicle dynamics.

Explore wheel rims types and manufacturing: steel, aluminum, magnesium, and carbon fiber rims; compare farming and forging, safety, rigidity, cost, and the impact of offset on brake fit.

Beadlock rims lock the tire to the rim using a multi-piece, precisely machined ring and screws, enabling faster starts on high-horsepower drag racing setups and preventing tire bead slip.

Learn how tire deformation under vehicle load alters the contact patch and shifts the center of rotation, creating leading-edge compression and trailing-edge loading that drive vehicle motion.

Analyze slip ratio by comparing wheel angular velocity to vehicle speed using loaded wheel radius, and how weight transfer on hills improves traction for front-wheel drive.

Explore how slip angle emerges from tire contact patch deformation under steering input, causing a difference between ground grip and rim motion, illustrated through tire testing data and simulations.
