Changing the tire size of your car leaves a lot of impressions like for better looks, better ride, etc. The tire size at the same time affects the car’s performance, the way you handle the car, the fuel consumption, etc. Hence, there are several things to consider before you change the wheel and tire size of your car.
There are different sizes of tires like 16in, 17in, 18in, 19in, 20in and 22in. Different wheels and tires have different weights. For example, a lighter wheel will give better performance as compared to a heavier wheel.
Here are things you need to know before you change the size of the tires and wheels.
- Changing The Car’s Tire Size Leaves An Impact On The Car’s Performance
Once you plan to change the size of tires you should take a test drive to see how the car performs with the big change. For example, if you insert a different size of tire in place of the existing Mercedes wheels and tires, it will largely affect the performance of the ride. It can either be good or bad.
- Upsizing The Wheels Of The Car
Generally, upsizing or plus sizing (means to increase the size of the tire) is done oftenly to enhance the looks of the car as well as increase the performance.
As far as performance is concerned, adding larger wheels (say, about 18in) can positively affect the performance. It could have great grip, act well when brakes are applied, you would feel comfortable while driving, and could enjoy the steer of the car. This could also negatively affect the acceleration and fuel due to the increased weight of the wheel.
- Downsizing The Tire Size
Downsizing refers to decreasing the size of the tire as compared to the previous tire size. Tire sizes like 17in or 16in wheels are great for the winter. This will enhance the winter performance of your car at a lower and affordable price.
You have to maintain the diameter outside as well. In order to do that, if you gain an inch of rim size, you have to lose an inch in the standing height of the tire. Decreasing an inch of the tire is okay for average handling.
- Know The Car Manufacturer’s Recommended Sizes
If you have a five or so year old car, you would love to modify it with a cool new set of wheels and tires. But remember that you can’t just bolt down any tire because of the looks. The wheels and tires should match the manufacturer’s recommendation.
You can do this by checking the vehicle’s handbook. You can use upgraded wheels in place of changing the size. If you are planning to replace the tire, then you should replace them with the tires that have the similar specification, size, load rating as well as size rating match to that of the original tire.
- The Pitch Circle Diameter (PCD) And Offset
Whenever you are upgrading the wheels and tires, you should check the Pitch Circle Diameter (PCD) and the wheel offset. PCD is the distance between the holes for the wheel studs whereas the wheel offset refers to the distance between the center line of the mounting surface of the axle hub and the wheel.
If the offset wasn’t checked and calculated, it will result in foul suspension, fail the brake calipers, and leave an impact on steering or lead to the problematic handling of the car.
You can use a tire size calculator to save you from doing the math. Additionally, the car maker always recommends the products best suitable for the car and that is why it is more advisable to stick to its original sizes. The cars have already been subjected to rigorous testing, strict criteria, and only then have been approved for suitability with each particular car and the model of the car.
There are manufacturers that could make a variety of designs for the similar model. And sometimes these are equipped with the new cars of the similar model. In fact, you can check with the seller about the wheel and tire options that could suit the specific model of a car.
