Wider tyres have a larger contact patch than narrow tyres

What actually influences the size of the tyre's contact patch? Is it the width of the tyre, or the profile? The simple answer that it is neither of these; the size of the tyre's contact patch is related to:the weight on the wheel the tyre pressure.For example, say that the weight on the tyre was 900lb, and the tyre pressure was 10 psi. That internal pressure means that each square inch of area can support 10lb, so, in this case, the contact patch will be 90 square inches. If the tyre pressure was 30 psi, the contact area would be 30 square inches, and if the pressure was 90 psi, the contact area would be 10 square inches. This has been found to be almost exactly correct for most tyres (the exceptions being so-called run-flat tyres, or tyres with extremely stiff sidewalls). For most other tyres, carcass structure will have an effect, but by far the major factor is tyre pressure.So, as you can see, the size of the contact patch of a tyre is not related to the width of the tyre - it is, in fact, proportional to the tyre pressure. What will change with the fitting of a wider tyre is the shape of the contact patch - it will get wider, but shorter longways.

Airless Tyres

Detailed Product Description

As its name suggests, the partly see-through Airless does not rely on air pressure for smooth riding, thus eliminating the risk of under-inflated or flat tyres. Instead, the rubber tread is supported by a circular row of ultra-strong translucent rings that absorb the impact from the road. It has an average of three-year guarantee and is easy to install. It is another puncture-proof concept, the Tweel (Tyre+Wheel), combines the tyre and wheel in a single module that resists shocks far better than today's separate tyres and wheels. Developed at Michelin's Paris, France, research center, the Tweel has been built for all luxury vehicles. The Tweel can withstand not only potholes but even land-mine blasts and keep moving. A third concept designed for electric and fuel-cell cars, this active wheel also delivers an integrated suspension system. By eliminating the need for a gearbox, clutch, shock absorbers and transmission shaft, the Active Wheel gives automakers more flexibility in designing the vehicles of the future.

Tyres Bead

Check the side wall of all tyres fro any damage, splits, lumps or bulges. Make sure that there is no seperation of the tread from the tyre and no visible signs of any of the ply or cord. Check that the tyre bead is correctly seated in the wheel rim and the wheel is not distorted or buckled.Check that the valve is correctly seated and is is good working order.Check that each tyre is of the correct size and pressure for the vehicle
and that each tyre matches the opposite tyre on each axle.Check the tread depth of each tyre. The legal minimum tread depth is 1.6mm for at least 75% of the tyre. Abnormal wear patterns could indicate worn shock absorbers, innacurate wheel alignment, bad tyre pressures or suspension faults
