Tire spacers are a good solution to your fitment issues. Every car would leave a certain wheel gap for slight changes in tire size. And most cars look better when the wheel gap is not so pronounced and the tires are flush with the fender. This also provides a better handling and ride quality.
By moving the wheels and tires further out from the suspension, tire spacers help prevent the tire from hitting the fenders or any other suspension parts. With so many options available, what tire spacers are best? In this post, we will explore the safe spacer types and explain the top brands.
Complete Tire Spacers Size Chart
To get the best wheel fitment, it is recommended to measure the wheel gap. 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. Repeat this on the front and rear wheels and you’ll soon get the perfect thickness. Here are the sizes for reference only:
- 3mm to 5mmm: Fits a big brake kit without significantly altering the wheel stance.
- 15mm to 25mm: A good start for those who seek a better wheel style and handling.
- 30mm to 40mm: Ideal for a powerful look and improved off-roading performance.
- 45mm to 50mm: Provides more stability and allow for a wide-body kit without rubbing.
Best Tire Spacers Types: Bolt-on vs. Slip-on
There are two main types of tire spacers that exist on the market: bolt-on types and slip-on types. The best type depends on the thickness you choose.
If you need above 25mm spacers, professional mechanics will recommend bolt-on types. The bolt-on types come with pressed-in wheel nuts. These bolt-on wheel spacers are bolted to the vehicle hubs and following the wheels are secured on the spacers with stock wheel bolts. Two sets of wheel fasteners allow you to achieve a full thread engagement without using longer bolts.
On the other hand, slip-on spacers directly slide over the wheel hub, and are sandwiched by the wheel and your vehicle’s wheel hub. Slip-on spacers can be thinner in sizes, like 3mm, 5mm, and 12mm. But you need new extended wheel studs. If you just need a few clearance to fit a big brake kit, then slip-on wheel spacers might be a good idea.
Who Makes the Best Tire Spacers for Sale?
Brand manufacturers focus on quality and performance. Before leaving the factory, BONOSS’s tech staff will do a series of inspections on the finished tire spacers to check for any defects. They measure the individual aspects of the spacers to make sure that they meet the design specifications. BONOSS offers several key advantages that make their spacers a top choice.
1. Active Cooling for Better Braking
BONOSS forged active cooling tire spacers come with petal-shaped grooves. The grooves allow the external cold air to flow continuously inside the spacer when it rotates. The air takes away the heat, actively dissipating heat for the braking system. This is good for performance brakes.
2. Knurling Surface for Better Experience
The side knurling design eliminates internal stress which contributes to more reliable product mechanical properties. The crisscross knurling pattern enlarges the cooling area which is good for the active cooling effect. BONOSS forged active cooling tire spacers boost the whole user experience.
3. Full-cone Lug Seat for Improved Stability
What’s better, BONOSS forged active cooling tire spacers come with full-cone lug seats. Full-cone seat design allows the studs and nuts to apply enough clamping force to lock the spacers, avoiding any potential loosening risks.
