What kind of car has different size tyres?
Some vehicles come with wheels of different diameters front and rear – tractors are an obvious example where the rear tyres are massively bigger than the front tyres. Some box vans have a standard-sized front wheel and a dual smaller wheel at the rear. In this case, the manufacturer will have set up the suspension geometry to account for this.
What happens when you drive with a different size tyre?
A wheel with a smaller diameter will measure a greater speed and distance travelled in relation to your actual speed, whereas a wheel with a larger diameter is at risk of rubbing on the inner guard. If the size difference is on the drive wheels, when you accelerate, it will pull towards the side of the smaller wheel.
Can you put narrower tyres on one side of the car?
However, you would not put a narrower tyre on one side of the car. Some vehicles come with wheels of different diameters front and rear – tractors are an obvious example where the rear tyres are massively bigger than the front tyres.
Why are the tyres on the back the same as the front?
The reason to keep the best tyres on the back is likewise safety in an emergency because if your back tyres are not as good or better than the front, you may end up looking where you have been and not where you are going. In this case the tires are the same diameter, so it’s not a real big deal.
