The right Dodge Ram rims make all the difference between a standard truck and a real head-turner. Whether for daily use, off-road trips, or US car meetups — rim choice equally influences aesthetics, driving behavior, and off-road capability. In this guide, we explain everything you need to know about Ram 1500 rims: from bolt pattern and correct offset to specific off-road recommendations and TÜV tips for Germany.
As specialists in off-road rims and US truck accessories, we know what questions Ram owners have. This article provides you with a solid basis for your next rim investment.
Dodge Ram Rim Basics: Bolt Pattern, Hub Diameter, and Generations
Before you decide on new Dodge Ram off-road rims, the technical fundamentals must be correct. The most important metric is the bolt pattern. For the Ram 1500, the bolt pattern changed with the fifth generation: The 4th Gen (DS, 2009–2018) uses 5x139.7 mm (5x5.5"), while the 5th Gen (DT, from 2019) switched to 6x139.7 mm (6x5.5") with six instead of five wheel studs. This difference is crucial: 4th Gen rims do not fit on 5th Gen and vice versa. For a comprehensive understanding, we recommend our article on bolt patterns for rims.
The hub diameter (center bore) for the Ram 1500 is consistently 77.8 mm. For aftermarket rims, either this exact value must be present or suitable centering rings must be supplied. Without a correct fit, vibrations and uneven wear can occur.
The wheel studs use the dimension 14x1.5 mm with conical lug nuts (60 degrees). Spherical lug nuts, common on European vehicles, are incorrect for the Ram. Regarding load capacity: Each rim must be able to support the maximum axle load. For the 1500, the permissible rear axle load is 1,300 to 1,600 kg — good off-road rims typically have a capacity of 1,100 to 1,400 kg per wheel.
4th Gen vs. 5th Gen (Classic vs. DT): Technical Differences
Although both generations use the same hub diameter (77.8 mm) and wheel studs (14x1.5 mm), they differ fundamentally in bolt pattern: 5x139.7 for the 4th Gen vs. 6x139.7 for the 5th Gen DT. In addition, there are other relevant differences in rim selection. Here is an overview:
| Feature | 4th Gen (DS/DJ, 2009–2018) | 5th Gen (DT, from 2019) |
|---|---|---|
| Bolt Pattern | 5x139.7 mm (5 lugs) | 6x139.7 mm (6 lugs) |
| Hub Diameter | 77.8 mm | 77.8 mm |
| Standard Rim Size | 17", 18" or 20" | 18", 20" or 22" |
| Recommended Offset (Aftermarket) | ET 0 to ET +20 | ET -12 to ET +20 |
| Front Brakes | 350 mm Disc | 370 mm Disc |
| Fender Clearance | Narrower, less room | Wider, more room |
| Max. Rim Width (without modification) | 9.5" | 10" to 12" |
| Suspension | Coil Spring / Air Suspension | Coil Spring / Air Suspension (4-Corner) |
| Wheel Studs | 14x1.5 mm | 14x1.5 mm |
The crucial difference lies in the fender width: The 5th Gen DT accommodates aggressive setups with lower offsets and wider rims better. While a 10-inch rim with ET -12 significantly protrudes on the 4th Gen, it sits almost flush on the 5th Gen. Also important: 17-inch rims can be tight on the 5th Gen due to the larger brake system — 18 inches are considered the minimum here.
Rim Sizes: 20, 22, and 24 Inches — What Makes Sense?
Every inch of diameter changes driving behavior, tire selection, and everyday usability.
20 Inches — The All-Rounder
Ram 20-inch rims are the most popular size for good reason: largest selection of off-road and all-terrain tires, fair prices, and optimal proportions. You can find suitable 20-inch tires in our shop. With a 20x10 rim and a 33-inch or 35-inch tire, you get an aggressive, off-road capable look.
22 Inches — The Show Factor
22-inch rims make a visual statement, especially on the 5th Gen DT. Disadvantages: thinner tire selection, higher prices, less sidewall. We also offer suitable 22-inch tires. For predominantly street-oriented use, 22 inches are acceptable, but disadvantageous off-road.
24 Inches — Only for Show
Severely limited tire selection, flat sidewalls, no off-road utility, complex TÜV registration. Only useful for pure show trucks.
Offset (ET): Flush, Slightly Protruding, or Spacers?
The offset determines how far the rim sits inward or outward. You can find basics on this in our Offset Guide. The factory offset for the Ram 1500 is ET +20 to +25. Aftermarket options:
- ET +20 to +15: Nearly factory dimensions. Unobtrusive, no problems with TÜV.
- ET +10 to 0: Flush with the fender (flush look). Generally registrable.
- ET -12 to -24: Aggressive off-road look, tires protrude. Fender flares needed on 4th Gen, often acceptable up to ET -12 on 5th Gen.
- ET -44 and lower: Extremely protruding. Only with wide fender flares, hardly registrable in Germany.
An alternative are wheel spacers: Common for the Ram in 25 mm and 38 mm. Advantage: gradual adjustment of aesthetics without new rims. Disadvantage: higher wheel bearing load and separate registration requirement.
Practical Tip: For 4th Gen ET 0 to +10, for 5th Gen DT ET -12 to 0 — sporty and TÜV-compliant.
Off-Road Rims vs. Street Rims for the Ram
Dodge Ram off-road rims differ fundamentally from street rims:
Off-road rims offer thicker wall thicknesses, reinforced spokes, and load capacities of 1,200 to 1,500 kg per wheel. Many are tested according to SAE J2530. Beadlock-style rings, matte finishes (Satin Black, Gunmetal), and increased chip resistance are standard. Some offer simulated beadlocks — real beadlocks are not permitted in Germany.
Street rims focus on finer spoke designs, polished or chrome surfaces, and lower weight. They quickly suffer damage off-road, and the load capacity is often insufficient for heavy off-road use.
Our recommendation: Even for occasional off-road use, off-road rims are worthwhile. The extra cost is minimal, and durability is significantly higher — even on German potholed roads.
Top-5 Rim Recommendations for the Dodge Ram
The models are available with various bolt patterns — make sure to choose 5x139.7 mm for the 4th Gen or 6x139.7 mm for the 5th Gen DT.

Popular Tire-Rim Setups (33s, 35s, 37s)
Only the right tire-rim combination creates a harmonious overall look. Three sizes have become established for the Ram:
33-inch Setup (approx. 838 mm diameter)
Tires: 275/60R20 or 285/55R20 | Rim: 20x9 or 20x10, ET 0 to +20 | Lift: Not necessary
The simplest entry: no suspension adjustment, no rubbing, trouble-free TÜV registration. Ideal for the daily driver with an off-road look.
35-inch Setup (approx. 889 mm diameter)
Tires: 35x12.50R20 or 295/60R20 | Rim: 20x10 or 20x12, ET -12 to +10 | Lift: 2–3 inches recommended
The sweet spot for off-roaders. Significantly more traction, impressive optics. Disadvantage: approx. 1–2 liters more fuel consumption per 100 km.
37-inch Setup (approx. 940 mm diameter)
Tires: 37x12.50R20 | Rim: 20x10 or 20x12, ET -18 to -44 | Lift: Minimum 4 inches
Pure statement. Requires adjustments to steering geometry and brake lines, TÜV registration is complex. For dedicated off-road builds.
Import, TÜV, and Registration: Specifics for US Trucks
While almost any wheel-tire combination can be legally driven in the USA, strict regulations apply in Germany. US trucks like the Ram are not homologated according to European standards, which complicates registration. Detailed information can be found in our article How to successfully register rims with TÜV – Your guide to hassle-free approval.
Required Documents
- Parts certificate according to §19 para. 3 StVZO: Describes permissible vehicles, rim sizes, and tire combinations. Must be approved and registered by TÜV, DEKRA, or GTÜ.
- Individual approval according to §21 StVZO: If no parts certificate exists. More expensive and time-consuming, but the last option.
- ECE approval: Rims with ECE marks are generally approved, but must match the vehicle.
Typical Pitfalls
- Tire overlap: If the tire protrudes beyond the body, registration will be denied. Fender flares help, but must also be registered.
- Clearance: Full steering mobility and suspension travel must be ensured.
- Speedometer adjustment: From 5 percent deviation due to larger tires, the speedometer must be adjusted.
- Brake compatibility: Brake calipers need sufficient space. On the 5th Gen, it gets tight below 18 inches.
Tip: Buy rims with a parts certificate that explicitly lists the Ram. Discuss the planned combination in advance with your inspection authority — many inspectors are unsure about US trucks. Bring COC papers or the individual operating permit.
Frequently Asked Questions (FAQ)
What is the bolt pattern for Dodge Ram 1500 rims?
For the Ram 1500: 4th Gen (until 2018) = 5x139.7 mm, 5th Gen DT (from 2019) = 6x139.7 mm. The hub diameter for both is 77.8 mm. More information in our Bolt Pattern Guide.
Do 4th Gen Ram rims fit on the 5th Gen (DT)?
No. The 4th Gen uses the bolt pattern 5x139.7 mm (5 lugs), while the 5th Gen DT uses 6x139.7 mm (6 lugs). Despite identical hub diameter (77.8 mm), the rims are not compatible. When purchasing, always pay attention to the correct generation.
What rim size is optimal for the Dodge Ram off-road?
20 inches with 9 to 10 inches width offer the best compromise of looks, tire selection, and off-road capability. 33-inch or 35-inch off-road tires provide sufficient sidewall height for damping and traction.
Do I need a certificate for aftermarket rims on the Dodge Ram?
Yes. A parts certificate according to §19 or an individual approval according to §21 StVZO is required. ABE or ECE alone is often not sufficient for US trucks. Registration by a recognized inspection organization is mandatory. Details in our TÜV Registration Guide.
What do wheel spacers do for the Ram 1500?
A wheel spacer moves the rim outward for a more aggressive look and increased stability. Common sizes: 25–50 mm. Disadvantages: higher wheel bearing load and separate registration requirement.
What tire size fits on 20-inch rims on the Dodge Ram?
From 275/60R20 (approx. 33 inches) over 295/60R20 to 35x12.50R20 (35 inches). Without lift: 275/60R20 or 285/55R20. With 2–3 inch lift: 295/60R20 or 35-inch tires are also possible without problems.
Conclusion: Finding the Perfect Dodge Ram Rims
The right rim depends on the intended use, budget, and willingness to deal with TÜV. For most Ram owners in Germany, we recommend a 20x10 off-road rim with ET 0 to +10 combined with a 33-inch or 35-inch all-terrain tire. This setup offers the best compromise of looks, off-road capability, and road suitability — and can be easily registered with a parts certificate.
Whether 4th Gen Classic (5x139.7) or current 5th Gen DT (6x139.7): With the right bolt pattern, suitable offset, and a high-quality off-road wheel, you'll get the maximum out of your truck.
