Most people use 4Runner wheel spacers to accommodate bigger rims and wider tires. If you want to keep the same wheel offset, you must have wheel spacers installed on all 4 tires. By installing proper wheel spacers on all 4 tires, you can easily make the vehicle look sporty and aggressive.
As long as they are high-quality, there are no significant disadvantages. By increasing the track width, the contact points of tires are expanded, which results in more stability. For many SUVs, this is good for improving driving safety. In this article, we’ll explore whether 4Runner wheel spacers replacement is safe, what factors affect their safety, and some considerations to keep in mind when installing them.
Choosing the Right 4Runner Wheel Spacers Replacement
Bolt Pattern (PCD):
Bolt patterns are specifically set by the manufacturer, helping narrow your wheel spacer choices. Figuring out the correct lug pattern is important before buying a set of alloy rim spacers:
- 5th Gen 4Runner (2025-2026): PCD=6×139.7mm, CB=95mm, Thread=M14x1.5mm.
- 1st-4th Gen 4Runner (1995-2024): PCD=6×139.7mm, CB=106mm, Thread=M12x1.5mm.
Correct Offset:
Wheel spacers reduce the offset. For example, if your stock wheel offset is +55mm, then a 35mm spacer will make the final offset +20mm.
Material:
The best wheel spacers for the 4Runner are made of high-strength materials like forged 7075-T6 aluminum alloys. For off-roading cars, aluminum spacers provide a balance of strength and weight. They won’t break easily.
Hub-centric:
Hub-centric means the large hole in the middle of the spacer is the exact fit for the vehicle hub. This creates a firm and stable wheel connection.
What Make BONOSS 4Runner Wheel Spacers the Best Choice?
Safety, precision, strength, and best experience are what set BONOSS apart from other spacers manufacturers. All BONOSS forged Toyota 4Runner wheel spacers are built strictly to meet international standards that can improve the quality of your own driving experience. BONOSS offers several key advantages that make their spacers a top choice.
1. Active Cooling for Better Performance
With the same price as most rim spacers, BONOSS forged active cooling 4Runner wheel spacers come with heat dissipation grooves to make brake cooling better. The heat dissipation grooves behind the spacers can boost the cooling efficiency. This is helpful in reducing brake thermal decay and improving road safety.
2. Forged Aluminum for Improved Safety
BONOSS forged active cooling 4Runner wheel spacers are made of forged 6061-T6/ 7075-T6 aluminum alloy. The tensile strength is up 572 MPa (AL7075-T6). High tensile strength gives it strong resistance to being pulled apart, making it resistant to bending and breaking. Therefore, forged aluminum wheel spacers with higher tensile strength are safer and better.
3. ISO Grade 12.9 Wheel Studs for Enhanced Stability
BONOSS forged active cooling 4Runner aluminum spacers come with ISO grade 12.9 wheel studs. These wheel studs are made of high-strength forged SCM440 alloy steel:
- Tensile strength≥1,220 MPa;
- Ultimate tensile load≥152,000 N;
- Hardness (HV)≥395;
- NSS≥500H.
High-strength wheel studs ensure a strong wheel-spacer-hub connection. With such high-strength hardware, your BONOSS forged active cooling Toyota 4Runner wheel spacers can bear more force without breaking.
Frequently Asked FAQ
Q: Can you fit 6×139.7 to 6×135?
A: Yes, with 6×139.7 to 6×135 wheel adapters, you can fit 6×135 wheels on a 2025 Toyota 4Runner easily.
Q: Can you tow with wheel spacers?
A: The answer is yes, high-quality wheel spacers (like BONOSS spacers) won’t affect a vehicle’s towing capacity.
Q: Do wheel spacers make wheels stick out?
A: Wheel spacers reduce the offset. The lower the offset value, the farther the wheels will sit outside. For example, a wheel with a 25mm spacer will stick outside more than a wheel with no spacer.
