Rear Wheels

Why Do Cars’ Rear Wheels Protrude Larger Than Their Front Wheels?

The design of automobiles today has changed a lot over the last few decades. Cars have changed significantly throughout the years, both in terms of outward design and interior layout. Some extremely fast rear-wheel drive vehicles use this design element. Vehicles with a rear wheel drive have bigger front wheels. This design was chosen for many significant mechanical, dynamic, and performance-related reasons in addition to aesthetic ones. We’ll talk about the inspirations behind this decision in this blog.

Significant Reasons

Power Distribution and Traction

Many vehicles, notably rear-wheel drive cars, have huge rear wheels for traction reasons. Since the wheels get power from the engine, they must have enough traction to deliver the power to the ground. A greater contact patch results from larger rear tires. This is the part of the tire that really makes contact with the pavement. Better traction is produced by a larger contact patch, which allows more of the tire to grab the pavement.

Weight is distributed to the back wheels when the car accelerates. The tires can withstand this added pressure without losing traction since the back axle carries more weight. You won’t be able to adequately transfer all of the engine’s power to the ground if the tires are too tiny. In this manner, the vehicle’s control and wheel spin will be lost.

Handling and Cornering

Large rear wheels can come in handy for handling and cornering. However, you need to give grip to all the wheels while turning, but if we talk about rear wheel drive vehicles, they rely heavily on their rear tires. When a car enters a corner, lateral forces act on it. Larger rear tires can better absorb and counter these forces. In addition, they help provide stability and prevent the tail from slipping.

Breaking Dynamics

Braking is an important function of the vehicle which is transmitted to all wheels. But for heavy rear-wheel drive cars, brakes play an important role. If seen, the front wheels handle most of the braking power. Therefore, the front brake discs of a vehicle are usually larger than the rear wheels. The rear wheel needs to remain stable during this process. Larger wheels help distribute braking forces more efficiently. They also prevent skids or uneven braking that can make the vehicle unstable.

Stylistic and Aesthetic Purpose

Cars with huge rear wheels have an unmistakable aesthetic appeal in addition to their practical advantages. The huge rear wheels’ aggressive stance exudes power, speed, and dynamism. This is particularly true for sports vehicles and muscle cars, whose designs attempt to radiate sheer power and performance.

Carrying Capacity for Loads

Larger rear wheels can assist the weight be distributed more evenly in cars that are intended to transport huge goods or more people. Larger wheels are great for vehicles with a lot of weight to carry or distribute between the axles since they can frequently support more weight.

Suspension and Ride Comfort

The type and quality of your vehicle’s suspension can be detrimental to wheel size. Larger best 20 inch wheels can allow the rear suspension components to see more performance. You just need to be sure that the car will remain stable even at high speeds or hard acceleration.

Tire Rotation and Wear

Tires wear at different rates depending on their position. The front tires experience the most steering forces and frequently experience faster edge wear when turning. Different sizes restrict vehicle owners from switching the front and rear tires, ensuring that tires are replaced as needed, according to their individual wear patterns.

Challenges with Large Rear Wheels


Replacing a large tire can be a very expensive and difficult task for you. Also, the wrong tire size can prevent the tire from rotating. Because of this, it can wear out quickly and since all tires are the same size, you will need to replace them.


Larger wheels and tires add weight to the vehicle, which affects overall vehicle performance, especially in terms of acceleration and fuel economy.

Complications in Changing

Having different tire sizes and finding the right size can be a hassle for you, especially when you need to change or carry a spare.

Potential Handling Problems

If the tires are not properly designed, a car with large rear wheels may experience under steer.

Final Words

The correct size of car wheels, like many designs, is very important. Granted, not all automobiles have larger rear wheels, but they tend to perform better in terms of traction, handling, and braking. It’s important to remember that not every design decision will always benefit you. The best wheel sizes can be better for many cars, especially when they are built for off-roading or city transportation.

Choosing a right wheel size makes it very important for you to strike a balance between many parameters to meet specific specifications. Large rear wheels serve a purpose in the automotive industry, whether it’s for speed, race track requirements, or aesthetic appeal.
