Wheel spacers on pickups are among the most popular modifications in the off-road and truck scene. Whether it's a Ford Ranger, Toyota Hilux, or Isuzu D-Max — hardly any other tuning part changes the look so effectively and simultaneously improves handling as noticeably as high-quality wheel spacers. Spacers on a pickup cause the wheels to move further outwards, giving the vehicle a more commanding appearance both visually and technically. But which type of spacer is suitable? How wide can you go in Germany? And when does TÜV registration become mandatory? This guide answers all questions — from technology to legal aspects, and the optimal combination with off-road rims.
What do wheel spacers do? Aesthetics, Stability, and Handling
Wheel spacers are far more than just an aesthetic upgrade. While the visual impact is the most obvious effect — wheels flush with the fenders give any pickup a more aggressive, stable appearance. Especially on pickups with a factory-narrow track, recessed wheels in the wheel wells are a negative visual. Wheel spacers remedy this deficit and ensure harmonious proportions.
But the benefits go further. Physically, a wider track shifts the wheel contact points outwards, thus increasing the vehicle's support base. Roll stability significantly improves — which is valuable especially for pickups with a high center of gravity due to hardtops or roof tents. In corners, the vehicle leans less, body roll is reduced, and the driver experiences a more direct driving feel.
In off-road conditions, a wider stance improves traction on slopes and during off-camber driving. When towing a trailer, the pickup benefits from better directional stability and reduced susceptibility to lateral oscillations. Braking performance also indirectly improves: the wider track distributes forces more evenly during cornering braking. In summary, wheel spacers offer a comprehensive upgrade in aesthetics, driving dynamics, and safety — provided they remain within the permissible limits.
Types of Spacers: Bolt Pattern Adapters vs. Wheel Spacers
The two fundamental categories are simple wheel spacers (through-hole spacers) and DRA systems (bolt pattern adapters with screw attachment). Understanding the differences is crucial for making the right purchasing decision.
Simple Wheel Spacers (SCC System): These spacers are mounted between the wheel hub and the rim. The wheel studs pass through the spacer, and the rim is secured with extended studs. Available in thicknesses from 3 to 30 mm, they are suitable for moderate widening. The original bolt pattern remains, and centering is done via the wheel hub. Important: From 10 mm thickness, longer wheel studs are required, as the original ones would otherwise not provide sufficient thread engagement.
DRA Systems (Bolt-on System): Here, the spacer is separately bolted to the wheel hub with its own studs. The rim is then attached to separate studs on the adapter. Available from 20 mm thickness, DRA systems allow widening up to 60 mm per side. Advantage: Double centering — adapter on hub and rim on adapter. H&R and Eibach use this system for their wider spacers with extensive ABE documentation.
In addition, there are bolt pattern changing adapters, which simultaneously change the bolt pattern. For pickups, this is rarely useful, as off-road rims are available with the appropriate bolt pattern anyway. Rule of thumb: Up to 15 mm per side for through-hole spacers, from 20 mm for DRA systems. Pay attention to high-strength aluminum alloys (T6061-T6) and the presence of an ABE. Further information on fitment can be found in our guide to wheel spacers for alloy wheels.
How wide can you go in Germany? Legal situation according to StVZO
The legal basis is the German Road Traffic Licensing Regulations (StVZO). According to §19 StVZO, the operating permit expires if modifications are made that affect compliance — wheel spacers clearly fall into this category. Especially relevant is also §21 StVZO, which regulates the operating permit for vehicle parts: Wheel spacers require an ABE (General Operating Permit) or a parts certificate according to §21 to be legally installed.
The central rule: The tires must not protrude beyond the vehicle body at any point. The wheel must end at least 5 mm within the outermost body boundary — at full steering lock and compressed suspension, not just when driving straight ahead.
The maximum possible widening depends on the original track width, tire width, and body width. There is no flat millimeter number. A guideline for pickups is 20 to 30 mm per side with standard tires. For pickups with fender flares, the leeway increases, as the flares are considered the outermost body boundary — which is why they are so often installed together with wheel spacers.
Even with an ABE for the wheel spacers, the overall combination of rim, tire, and spacer must fit. An ABE for 30 mm wheel spacers is of no use if the tire protrudes beyond the body as a result. The responsibility lies with the owner.
TÜV Registration for Wheel Spacers: When is it mandatory, what are the costs?
Whether a TÜV registration is required depends on the approval documents. Three scenarios:
ABE available: With a General Operating Permit for your vehicle model, no TÜV registration is necessary. The ABE document must be carried in the vehicle. All requirements — tire size, rim width, offset — must be precisely met.
Parts certificate available (§19 para. 3): A parts certificate requires an installation inspection by an expert at TÜV, DEKRA, GTÜ, or KÜS. Costs vary depending on the testing organization and effort. Our guide on registering rims with TÜV describes the process in detail.
No documents — individual approval (§21 StVZO): The most complex and expensive option. Costs depend heavily on the testing organization and the scope of the inspection. The risk of rejection exists. We strongly recommend brand products with ABE or parts certificates — the extra cost of H&R, Eibach, or SCC pays for itself immediately.
If wheel spacers are installed together with other modifications (rims, suspension), a combined approval is worthwhile. The most important note: Without valid papers, you risk the loss of the operating permit and problems with insurance in case of damage.
Wheel Spacers + Off-Road Rims: The Right Combination
If you want to install off-road rims and widen the track at the same time, you need to understand the offset (ET). The ET indicates how far the mounting surface of the rim is offset from its centerline. High ET (e.g., +45) = wheel sits further inward. Low ET (e.g., -10) = wheel sits further outward.
Off-road rims typically have a significantly lower ET than stock rims. A Ford Ranger comes from the factory with ET +55, many off-road rims offer ET +20 to -12. Changing from ET +55 to ET +20 already results in an effective 35 mm track widening per side — without any spacers.
The calculation: Every millimeter of ET reduction moves the wheel one millimeter outward. A 20 mm wheel spacer has the same effect as an ET reduction of 20 mm. If you have a stock rim with ET +50 and install 25 mm wheel spacers, this effectively corresponds to ET +25.
A good example: The RID R01 Offroad-Rim is available with ET 0 and already generates 55 mm of track widening per side on a Ford Ranger (stock ET +55) — without any additional spacers. Combined with a 1,250 kg load capacity and TÜV approval, it is one of the most elegant solutions for giving the pickup a wider and more stable stance.
Our recommendation: First determine the maximum permissible track width. Then choose off-road rims with a suitable ET. Only if the desired rim is not available in the ideal ET, compensate the difference with wheel spacers. This minimizes components between the hub and rim and is the cleanest solution.
Wheel Spacers by Vehicle: Ranger, Hilux, D-Max, Ram, Amarok
Ford Ranger (from 2012): Bolt pattern 6x139.7, center bore 93.1 mm, stock ET +55. Eibach offers 21 to 60 mm, H&R DRM systems with 40 mm. For Ford Ranger off-road rims (typically ET +20 to +0), additional wheel spacers are often superfluous.
Toyota Hilux (from 2015): Bolt pattern 6x139.7, center bore 106 mm. Widening from 20 to 60 mm available. Pay attention to at least 1,250 kg wheel load approval per disc. Suitable combinations can be found with our Toyota Hilux rims.
Isuzu D-Max (from 2020): Bolt pattern 6x139.7, center bore 108.1 mm. Up to 30 mm per side with stock tires is fine, beyond that fender flares are necessary.
Ram 1500 (from 2019): Bolt pattern 6x139.7, center bore 77.8 mm. Wide body offers plenty of room — up to 40 mm per side possible with stock tires. Note the M14x1.5 thread specification.
VW Amarok (from 2023): Based on the Ranger platform, bolt pattern 6x139.7, center bore 93.1 mm. Ranger wheel spacers often fit — still check vehicle approval in the ABE. The predecessor (until 2022) uses 5x120.
Risks and Common Mistakes
Too wide wheel spacers: The most common mistake. If tires protrude beyond fenders, the operating permit expires. Check clearance at full steering lock and compressed axle — what fits when driving straight ahead can rub when steering.
Too short wheel studs: With through-hole spacers, thread engagement decreases. Rule of thumb: At least 1.0 times the bolt diameter engagement — for M14, that's 14 mm. Too short bolts can shear off and lead to wheel loss.
Cheap products without papers: Wheel spacers without ABE or material proof save money in the short term, but cost in the long term due to denied TÜV approval or material failure. Brand products made of T6061-T6 aluminum cost only 30 to 50 euros more per set.
Wheel bearing wear: Any widening creates additional tilting moment on the wheel bearings. Up to 25 mm per side, the effect on robust pickup bearings is minor. From 40 mm per side, maintenance intervals shorten. Watch out for noises, vibrations, or bearing play.
Forgetting torque: After mounting, wheel bolts must be re-torqued after 50 to 100 km. For DRA systems, this applies to both adapter and wheel bolts. Always use a calibrated torque wrench.
FAQ — Frequently Asked Questions about Wheel Spacers on Pickups
Are wheel spacers on a pickup allowed without TÜV?
Yes, but only with an ABE that covers your vehicle model and whose conditions are fully met. The ABE document must be carried. For parts certificates, an installation inspection and registration are mandatory. Without papers, an individual approval according to §21 StVZO is necessary.
How wide can wheel spacers on a pickup be at most?
There is no general maximum width. Tires must end at least 5 mm within the body boundary — at full steering lock and suspension compression. Typically, 25 to 40 mm per side with stock tires, with fender flares up to 60 mm.
Do wheel spacers affect the speedometer or steering?
Not the speedometer, as the rolling circumference does not change. However, the steering scrub radius increases, which can lead to a heavier steering feel. Up to 30 mm per side, the effect on pickups with power steering is hardly noticeable.
Can I combine wheel spacers with a lift kit?
Yes, and the combination is even useful: The wider track compensates for the increased tendency to tip over due to the lift. Important: For combined modifications, a joint approval is required. Individual ABEs are not sufficient if the combination is not explicitly approved.
Which manufacturers offer wheel spacers for pickups with ABE?
H&R (TRAK+ and DRM systems), Eibach (Pro-Spacer System 4 and 8), and SCC offer extensive pickup programs with ABE or parts certificates. Prices: 80 to 350 euros per axle. We recommend only brand products with complete approval documents.
Conclusion: The Right Wheel Spacers for Your Pickup
Wheel spacers on a pickup improve aesthetics, stability, and handling in one step. Whether subtle 20mm spacers or a powerful 50mm widening with fender flares and off-road rims — it's crucial to rely on brand products with ABE, use the correct bolt length, and comply with legal requirements. Often, the smarter way is an off-road rim with a low offset: RID Wheels with ET 0 offer an integrated track widening that makes additional spacers superfluous — fewer components, fewer sources of error, best off-road design.
