Generally, 1-inch wheel spacers give you a little more width without replacing your current wheels with wider ones. They have been existed and widely used for decades. A common misconception is that wheel spacers will be the weak part of the hub-to-wheel connection. Actually, the vehicle’s wheels are secured to the corresponding hub assembly by a clamping force achieved by tightening the lug nuts of each wheel. This allows all forces to be transmitted through each vehicle’s wheel and its corresponding axle. Therefore, the weight of your car will not be placed on any 1-inch wheel spacers that are installed. On the contrary, the wheel spacers simply serve as an extension of the original wheel hub surface. The hub-to-wheel connection doesn’t change. Therefore, as long as you use top-quality 1-inch wheel spacers and correctly install them, they are completely safe. Since they are important components of wheel fitment, there are a few precautions to further improve safety.

Will 1-inch Wheel Spacers Fit My Vehicle?

If you would like to use 1-inch wheel spacers, make sure they are properly fitted. Spacers will reduce the wheel offset which corresponds to the thickness. For instance, a 1-inch wheel spacer will reduce 25mm wheel offset. If your wheel offset is +45mm, then it will become +20mm. The lower the offset, the wheel will stick out more. If your wheels have low offset, then 1-inch wheel spacers may make the wheels rub against the inner wheel well when operating a U-turn. Thus, before shopping for 1-inch wheel spacers, it is better to measure the fender clearance.

Assuming you have aftermarket wheels, install them on your vehicle. Then use a straight edge ruler to measure the distance from the inner fender lip and the outside edge of your wheel tires or rims. This distance is the perfect thickness to get the wheels flush with the fender and the maximum amount that wheels will not rub the wheel well. If the result is above 1-inch, then installing 1-inch wheel spacers will have no problems. People like to make their vehicles look muscular and powerful, they will push the wheels out a lot. In this case, you can fit 1.5-inch or 2-inch wheel spacers as well, to some extent.

What Are the Best 1-inch Wheel Spacers?

When talking about the best 1-inch wheel spacers, material selection can be very important. Both forged Aluminum 6061-T6 and 7075-T6 feature good hardness and toughness, excellent corrosion resistance, and wear resistance characteristics. Particularly, the forging process eliminates the porosity, ensuring structural integrity. This makes the aluminum 1-inch wheel spacers not easy to break. The Aluminum wheel spacers are lightweight with exceptional strength. Reducing unsprung weight is an important advantage for performance.

Since the wheel studs and lug nuts use a clamping force to secure the spacers and wheels. If the studs or lug nuts are not strong enough to support this force, they will likely be bent by road impacts. The provided wheel studs of BONOSS 1-inch wheel spacers are made of high-strength forged SCM440 alloy steel. They have achieved ISO standard grade 12.9, tensile strength≥1,220Mpa, ultimate tensile load≥152,000N, hardness (HV)≥395, NSS≥500H. With higher strength, your 1-inch wheel spacers can bear more force without breaking.
