OE Wheels CV32 20×9 RST Style Wheels
The CV32 wheels feature a factory-inspired RST split-spoke design with a gloss black finish. Best for Silverado 1500, GM full-size SUVs, and other 6-lug GM trucks. These wheels are a direct fit for 6×139.7 bolt patterns with a +28 offset, making them a solid choice for owners seeking a balanced, aggressive look without modification. Caution: verify your vehicle’s specific model year compatibility as some trims may require minor adjustments.
OE Wheels CV37 20 Inch Rims
CV37 rims are designed for Sierra 1500 and similar GM trucks with a 6×139.7 bolt pattern and a 28mm offset. They provide reliable fitment for Escalade, Silverado, Suburban, and related models. Best for owners who want a clean, performance-oriented look with a stable stance. Caution: ensure hub bore compatibility (78.1mm) to avoid vibration or seating issues at high speeds.
OE Wheels CV36 20 Inch Rims
CV36 rims are another solid option for GM’s 6-lug lineup with a 6×139.7 bolt pattern and 28mm offset. Best for owners seeking a gloss black machined look with reliable hub compatibility and a strong overall fit for Silverado/Sierra families. Limitation: ensure a correct backspacing of about 6.2 inches to avoid rubbing on full-turns with larger tires.
Quadboss QBT680 Mud 36×9.5-20
QBT680 is a mud-terrain tire designed for off-road use. It’s built with 6-ply bias construction to offer durability in rough conditions. Best for off-road enthusiasts who need aggressive traction and a smaller sidewall flex. Caution: 36×9.5-20 tires may increase road noise and impact ride comfort on paved highways compared with highway-focused tires.
OE Wheels DG65 20 Inch Rims
DG65 rims pair with 5×139.7 bolt patterns and a 19mm offset, designed for Ram 1500 and other 5-lug configurations. Best for owners seeking a bright, polished look with a slightly deeper dish for a confident stance. Caution: check fitment for 2011-2026 Ram 1500 models and drive-line clearance in certain wheel arches.
Buying Guide: Key Purchase Considerations
- Wheel diameter and tire compatibility: A 36-inch tire on a 20-inch rim is a specialized fit often used in off-road or custom builds. Confirm tire sidewall height, backspacing, and overall diameter to avoid rubbing and gearing issues.
- Bolt pattern and offset: Match the vehicle’s bolt pattern (commonly 6×139.7 or 5×139.7 in these options) and offset close to factory, typically around 28mm for GM 6×139.7 setups, to maintain steering feel and ride height.
- Load rating and construction: For off-road use, favor tires with higher load ratings (e.g., 6-ply bias or better) and durable sidewalls to resist punctures and impacts.
- Material and finish: Gloss black or polished finishes enhance aesthetics but consider maintenance and corrosion resistance based on climate and road conditions.
- Vehicle type and intended use: Trucks and full-size SUVs with heavy-duty needs benefit from wheels and tires designed for 6-lug hubs and higher payloads; smaller crossovers may require different geometries.
- Rubbing and clearance: Larger tires can rub fenders or suspension components. Check wheel backspace (roughly 5.8–6.2 inches in these examples) and note any lift requirements for adequate clearance.
- Installation and safety: If unsure, consult a professional for proper mounting, balancing, and alignment checks to prevent issues during operation.
Frequently Asked Questions
- Can I fit a 36-inch tire on a stock 20-inch rim without modifications?
– It depends on the tire width, wheel offset, and vehicle clearance. Some setups may require strategic adjustments or trimming to prevent rubbing. - Are 36×9.5-20 tires suitable for highway driving?
– They are typically aimed at off-road performance and may cause more road noise and lower fuel economy compared to highway-oriented tires. - Is a 28mm offset appropriate for most GM 6×139.7 applications?
– For many GM trucks and SUVs, a 28mm offset aligns the wheel well with the tire, but verify with your specific model year and suspension setup. - What should I consider about hub bore sizing?
– Ensure hub bore compatibility (e.g., 78.1mm or 77.8mm) to avoid improper seating, vibration, or center cap issues. - Do these wheels fit 5-lug Rams or only GM vehicles?
– Some wheels listed are designed for GM 6-lug patterns, while others (like DG65) support 5-lug Rams with compatible offsets; always verify the exact bolt pattern for your vehicle. - Will lifting or leveling affect 36-inch tires on 20-inch rims?
– Lifts or leveling kits may be necessary to maintain clearance and prevent rubbing; check guidance for your specific truck and tire size.
