Before using any tyres, you should try and make sure it's the right tyre for your vehicle because most accidents I have witnessed so far are caused by using the wrong tyres. If the tyre isn't suitable for your car, please don't use whether it's bigger or smaller. Safety should come first.

No, it is not recommended to use a car tire with a larger diameter than the manufacturer's recommended size, even if it has the same weight. This is because the size of the tire is designed to match the specifications of the vehicle, including the suspension, brakes, and other components. Using a tire with a larger diameter can cause clearance issues and affect the accuracy of the speedometer, which can lead to unsafe driving conditions. It is important to always follow the manufacturer's recommended tire size for your vehicle.

You can use different diameter tires on a car as long as the rims still fit around the break rotors. Say your rim is 18 , you could use anything up to 18 on it, like 17 for example.

Also keep in mind that the larger the tire is, the more you will spend on gas as the "touching" area on the ground will be bigger, so the drag will be bigger, making you use more gas.

When it comes to using cars and anything that is related to the car, I always have this preference to using car parts that are from a trusted and reliable company that have been in business for years without much cases.
Now when it comes to using car tyres, there is one particular company I prefer using their tyre products and the company is called Mechelline tyres. Tyres are very important to the safety and smooth driving and it's the reason why the road authorities here don't joke with inspection of expired tyre used by some drivers. A lot of accidents have been caused by using bad tyres because they blow up when you least expected to and this puts so many people in risk of getting involved in an accident. Using a reputable car tyre company products will help you use the best tyres for your car.

Tyres are very essential part of the vehicle which mustbe  taken very serious and must be used in accordance to rules and regulations to avoid accidents.

Many accidents today are caused by bad condition of the vehicle tyres! It is either the tyre is overguaged or underguaged which whichever one is never good for life's.

Many car owners especially the commercial vehicles believe in over guaging the cars and using bigger tyres of higher diameter to carry more loads. This I believe is never bad but it is important to note that, cars are produced with special calculations and designs to fit in or for certain purpose.

In the first place, it is not ideal to replace a car tyre with wider one because of many things that might affect it. Alignment is one important part of a car which when it is not done properly might cause the wearing and tearing of the tyre especially ddue to the larger than normal diameter and the result will be disaster.

Yes, this is possible. The tyres with a larger diameter will have a higher load capacity and will be able to support a heavier weight than the ones with a smaller diameter. However, the ride quality of the car may be affected due to the differences in the ride height.

Using car tires with a larger diameter while keeping the weight the same can have several effects on your vehicle:

1. **Speedometer and Odometer Accuracy:** A larger diameter tire will cover more ground with each revolution, so your speedometer and odometer will read lower than your actual speed and distance. This can lead to inaccurate readings and potentially legal issues if your speedometer underestimates your speed.

2. **Clearance Issues:** Larger tires can affect the clearance between the tires and the vehicle's body or suspension components. This can lead to rubbing, especially during turns or when going over bumps.

3. **Handling and Performance:** Larger tires can change your vehicle's handling characteristics. They may provide better traction and stability, but they can also make the steering feel heavier and affect acceleration and braking performance.

4. **Fuel Efficiency:** Larger tires can negatively impact fuel efficiency. They create more rolling resistance, which means the engine must work harder to move the vehicle.

5. **Transmission and Gear Ratios:** Changing tire size can affect the vehicle's transmission and gear ratios, which can impact acceleration and overall performance.

If you want to change to larger tires, it's important to consider these factors and consult your vehicle's manual or a qualified mechanic to ensure that the new tire size is compatible with your vehicle. Changing tire size can be done, but it should be done with careful consideration of these factors to avoid safety and performance issues.

Using a car tire with a larger diameter but the same weight can have several implications. While weight is one factor, you also need to consider other aspects such as clearance, speedometer accuracy, and handling characteristics. A larger tire may affect the accuracy of your speedometer, alter the gear ratios, and potentially cause clearance issues, especially if the tire rubs against the fenders or other components.

It's generally recommended to stick to the manufacturer's recommended tire size for your vehicle to ensure optimal performance, safety, and handling. If you're considering changing tire sizes, it's advisable to consult with a professional mechanic or refer to your vehicle's manual for guidance on acceptable tire sizes.
