30mm wheel spacers will add -30mm wheel offset. Generally, you wouldn’t need wheel spacers if buy the right offset wheels. However, for those who have a limited budget, installing 30mm wheel spacers to fit wheels will be a good idea. Now, let’s simply explain the relationship between the wheel offset and spacers.
If you get new wheels installed and find that the wheels stick into the wheel arches, then it comes to offset/ET matters. Wheel offset means the distance in millimeters from the wheel’s centerline to the mounting plate. Since the mounting plate can be either in front of, coincide, or behind the centerline, the offset can be either positive, neutral, or negative. The lower the offset is, the further the wheels are outwards from the hub assembly. On the contrary, the higher the offset is, the more the wheels are close to the vehicle hub.
What Do 30mm Wheel Spacers Do for Offset Wheels?
By pushing the wheels out, 30mm wheel spacers reduce 30mm offset. An excessive positive offset wheel can cause the rims and tires to rub against the suspension components. It can also negatively affect your car’s handling, making it potentially dangerous to drive. Nobody wants the car to look like there’s a huge hole in the fender. If you have +60mm offset wheels, a 30mm spacer would make them +30mm. To some extent, wheel spacers provide the same effect as lower offset wheels. If you put 30mm wheel spacers on each wheel, that adds a total of 60mm track width. A wider track enables your tires to better grip the road surface, the resistance to rollover enhances, even if you’re driving during wet weather or unfavorable conditions, your vehicle doesn’t lose gripping power. This adds safety to your ride.
Will My Car Fit 30mm Wheel Spacers?
Remember not all vehicles or wheels can fit 30mm wheel spacers. Before getting a set of wheel spacers, you need to verify how much wheel gap do you have. After installing your new rims, take a straight edge and place it against the outermost part of the rims/tires, then measure from the outside wheel to the fender line to see how much space you have available. If the value is above 30mm, then you are free to use 30mm spacers. If not, then you may meet rubbing issues. Depending on this wheel gap, thicker wheel spacers can be installed without a problem.
It is typical to install 30mm wheel spacers on all four wheels. This keeps the same proportional track (distance between tires tread centers on the axle) from front to rear. If torqued properly, they will never come off. But an exception can be made if the front wheels have different track widths from the rear wheels. All in all, it depends on your design. 30mm wheel spacers create more space between tires to accommodate bigger wheels and tires. When combining 30mm spacers with large rims and broad tires, they will give your car a sporty and sturdy look.
