How do I know which tires will fit my car?
This information is usually inside your car’s doorjamb, in your owner’s manual. To ensure your current tire or a replacement tire you may be looking at matches your vehicle’s requirements, it will be good for you to understand how tire sizing works. Tire Sizing It’s imperative that you select a tire designed to fit your wheel size and vehicle type by: Identifying the tire size. Identifying the load index and speed symbol. Ensuring your size, load index and speed matches your current vehicle year, make and model.To inform your decision process, you’ll need to know your vehicle’s tire size and speed rating, and you’ll also want to consider how many miles you’ll get out of any new tires you are considering (this is called tread wear).
Do all tires fit on all cars?
Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size. That being said, a vehicle with bigger rims will often be able to fit larger tires than other vehicles. As mentioned above, wider tires usually increase fuel consumption. So, what about narrower tires? Narrower tires have a smaller contact patch, leading to less friction and lower rolling resistance with the road. The slimmer shape and less weight also help reduce wind resistance while driving.Fuel consumption — The less friction your vehicle produces, the lower your steering effort, which also means less fuel consumption. Wide tires provide for more friction, making your vehicle consume more fuel, whereas narrow tires cause your car to consume less fuel because they have lower amounts of friction.Contrary to popular belief, larger-diameter tires are generally less fuel-efficient. The key aspect of tire size is how it affects the engine’s torque curve relative to the vehicle’s weight.Wet condition driving — Wide tires are better for driving in wet weather since they have sipes, which help to trap and remove water from the contact surface. Narrow tires have sipes as well, but since they have a smaller surface area, they have less of them.
