Why the back wheel of tractor is bigger than front wheel?

A tractor engine is very heavy and is located at the front of a tractor, potentially causing it to tip nose first. Larger heavier wheels at the rear of the tractor distribute this weight more evenly to counter a heavy front.

Why are front tires smaller than rear?

Because of the caster angle, camber angle of front tire is higher than the rear tire which requires the front tire cross sectional profile to be more circular. So if we increase the width of the front tire to match the rear one, fromt tire mass would significantly increase.

Are front and back wheels the same size?

Typically they are not. In the vast majority of road cars, all the wheels are identical. However, in high performance cars, the rear wheels may be wider than the front (but the same diameter) to allow more power distribution to the rear axle.

Why are front tractor tires tilted?

Why do the front tires on my tractor appear to be off center? The front wheels are intended to have positive camber (toe-in). The positive camber or “toe-in” is generally used in vehicles for off-road use. In such vehicles, the positive camber angle helps to achieve a lower steering effort.

Why two tyres of a tractor are very wide and huge?

Large and wide tyres have a larger surface area. … So for a given force the pressure will be reduced with a larger surface area. Reducing pressure reduces the damage that the wheels do to the ground. Thus the amount that the wheels sink into the ground will be reduced.

Why do tractors have broad wheels?

Explanation: Pressure exerted by an object is inversely proportional to its surface area. So, tractors have broader tires so that the pressure exerted by them on soft soil (typical for farmlands) is comparatively less and they do not sink in as they are very heavy indeed.

Is it OK to have mismatched tires?

A car with mismatched front and back tires should still be usable, especially if it is a two wheel drive vehicle. … If the tires are different sizes then they may also wear at different rates, and you’ll be shopping for new tires sooner than you think. Functionally, mismatched tires will wear out at different rates.
