The Bigger the Wheels, the Bigger the Risks

WheelsMost of the time, car owners aren’t satisfied with the standard appearance of their newly-bought vehicles, so they look for ways to make them exclusively theirs. One of the simplest ways to add individuality to a car is by giving it a new set of wheels. The most popular choice for many car owners are large rims.

What’s good about large wheels is that they give cars better handling and performance. Rims such as Porsche Fuchs wheels, for instance, is a common sight in early 911 models from the 1960s. Most wheels come in 17”, 18”, and 19” sizes. But, does the wheel size, particularly for large ones, really matter?

How Larger Wheels Increase Risks

Larger wheels make cars more attractive. The downside of getting such rims, however, is you’re almost certainly sacrificing the size of tires to compensate that of the wheels. This, in most cases, could increase your risks of crashing as imbalanced wheel-tire combination affects the car’s brakes and suspension.

Even if the overall diameter of your new wheel-tire combination is the same as the one the car has when it got out of the factory, it doesn’t make the unit risk-free. In general, metal weighs more than rubber and air. Vehicle brake and suspension systems work efficiently for a certain unsprung weight, which includes wheels and tires, as well as the axles.

With more metal than rubber and air to contend with, your car’s shock and spring absorbers may be bound to premature wear out. Cars also take longer to stop due to this added weight from the wheels.

The Danger of Thin-walled Tires

Many car authorities say, however, that it’s not necessarily illogical to go for larger wheels. You can still install those rims as long as you also upgrade the suspension that handles the additional weight. In addition, you can’t simply put thinner tires on larger wheels because it will only hurt the vehicle more.

Thinner tire walls don’t absorb as much impact, increasing the blow that the car receives when you drive through bumps. This problem becomes more serious if you’re driving an SUV. As this vehicle type is bigger and heavier, it increases the possibility of a blowout if the thin-walled tires hit a bump or a rock.

Before you spend money on new wheels and car servicing, make sure you get the right advice from the right people. If there is one thing you need to prioritize in car upgrades, it should be vehicle safety.
