Understanding the Coachmen Beyond 22RB Towing Profile
The Coachmen Beyond 22RB is a compact travel trailer that blends tiny-house efficiency with off-grid capability. For owners considering towing this unit, understanding its weight, tire specifications, and trailer configuration is essential for safe and reliable travel. This guide focuses on the specific towing requirements of the 22RB, particularly as they relate to tiny-house-style tires and trailer systems.
Weighing in at approximately 4,200 pounds dry and with a GVWR of 5,500 pounds, the 22RB requires a tow vehicle capable of handling a loaded trailer. The standard tire size is ST205/75R15, which is common for smaller travel trailers but demands careful attention to load capacity and inflation. Below, we answer the most pressing questions about towing this tiny house on wheels.
What Are the Exact Tire Specifications for the Coachmen Beyond 22RB?
The 22RB ships with Goodyear Endurance ST205/75R15 tires as standard equipment. These are specially designed for trailer applications, featuring stronger sidewalls and higher load ratings than standard passenger tires. Each tire can support up to 1,760 pounds at 50 PSI when properly inflated. The load capacity is critical because the 22RB’s dry weight distribution places roughly 60% over the axles.
Owners should check the tire pressure before every trip. Under-inflation can lead to heat buildup and blowouts, especially when towing at highway speeds. The recommended cold tire pressure is 50 PSI for all four tires. If you plan to carry heavy gear like fresh water (approximately 40 gallons), remember that water weighs about 8.3 pounds per gallon, adding 332 pounds to the trailer’s load. This directly impacts tire load margins.
| Specification | Value | Notes |
|---|---|---|
| Tire Size | ST205/75R15 | Trailer-specific |
| Load Range | D | 8-ply rating |
| Max Load per Tire | 1,760 lbs | At 50 PSI |
| Wheel Bolt Pattern | 5×4.5 inches | Standard for this class |
| Recommended PSI | 50 (cold) | Check before towing |
| Spare Tire | Includes same size | Usually mounted on rear |
For owners upgrading to all-terrain tires for boondocking, ensure the replacement maintains the same load rating. The 22RB’s suspension system uses leaf springs with a 3,500-pound axle rating each, so exceeding tire load limits can damage both tires and axles.
How Does the 22RB’s Hitch Weight Affect Tow Vehicle Selection?
The Coachmen Beyond 22RB has a dry hitch weight of around 480 pounds, which increases to approximately 550-600 pounds when loaded with camping gear and a full propane tank. This hitch weight represents about 10-11% of the total loaded trailer weight, which is within the ideal range for stable towing. Under 10% can cause dangerous sway, while over 15% can overload the tow vehicle’s rear axle.
For a mid-size SUV or truck towing this tiny house, a weight-distributing hitch is recommended when the trailer’s loaded weight exceeds 5,000 pounds. Many 22RB owners use a 600-pound-rated weight-distribution system to maintain level ride height. If you tow with a full-size SUV like a Chevrolet Tahoe (maximum tow rating around 8,400 pounds) or a Ford F-150 (up to 13,200 pounds), the 22RB is manageable without a weight-distributing hitch, though it still improves stability.
Check your tow vehicle’s payload capacity carefully. The 22RB’s hitch weight plus passengers, gear, and tongue weight of the hitch itself can quickly consume the payload. For example, a 2024 Ford Explorer with a payload of 1,500 pounds leaves only around 900 pounds after accounting for the trailer’s hitch weight. This is adequate for two occupants and light cargo, but not for a family of four with camping equipment.
What Are the Best Tire Maintenance Practices for This Trailer?
Because the 22RB uses relatively small 15-inch tires, they spin faster than larger tires at highway speeds, generating more heat. Owners should follow these maintenance steps: first, inspect tires for sidewall cracks or bulges monthly. Second, check the tire pressure when tires are cold (before driving). Third, rotate tires every 5,000 miles to ensure even wear. Fourth, replace tires every 4-5 years regardless of tread depth because trailer tires age from UV exposure and ozone.
Many 22RB owners find that upgrading to a tire pressure monitoring system (TPMS) provides peace of mind. Wireless sensors that screw onto each valve stem can alert you to slow leaks or rapid pressure drops. A TPMS is especially valuable when towing through remote areas where finding tire repair is difficult. For more on optimizing your 22RB’s tiny house systems, see our Coachmen Beyond 22RB: Space-Saving Table Review and Alternatives guide, which covers interior layout considerations.
How Does the 22RB’s Trailer Frame and Suspension Impact Towing?
The 22RB sits on a powder-coated steel frame with a torsion axle suspension system. Unlike leaf springs, torsion axles use rubber cords inside a square tube to absorb road shocks. This design provides a smoother ride for the trailer and reduces the likelihood of axle damage from potholes. However, torsion axles have a finite lifespan of about 10-15 years before the rubber degrades and needs replacement.
The tongue length is around 3 feet, which is standard for a trailer of this size. Owners towing with shorter-wheelbase vehicles (under 110 inches) may experience more trailer sway due to the leverage ratio. Adding a friction sway control bar is a low-cost upgrade that dramatically improves handling. The 22RB also features electric brakes on both axles, which require a brake controller in the tow vehicle. A proportional brake controller is preferred because it applies braking force based on the vehicle’s deceleration, rather than a fixed time delay.
Tire clearance is another consideration. The 22RB’s wheel wells allow for up to 31-inch diameter tires if owners wish to lift the trailer for off-road use. However, lifting changes the center of gravity and can affect stability. Most owners stick with the 27-inch diameter OEM tires.

What Are the GVWR and Payload Limits, and How to Stay Within Them?
The Gross Vehicle Weight Rating (GVWR) of the 22RB is 5,500 pounds. Subtracting the dry weight of approximately 4,200 pounds leaves 1,300 pounds of available payload for water, propane, gear, food, and personal items. However, the dry weight does not include options like the solar package, extra batteries, or upgraded appliances. A fully optioned 22RB may have a dry weight closer to 4,500 pounds, leaving only 1,000 pounds of payload.
Here is a typical payload breakdown for a long weekend trip with two people:
- Fresh water (40 gallons) = 332 pounds
- Propane (two 20-pound tanks) = 80 pounds
- Food and kitchen supplies = 150 pounds
- Clothing and bedding = 100 pounds
- Tools, chairs, outdoor gear = 200 pounds
- Batteries (two group 27) = 120 pounds
- Total = 982 pounds
This leaves 18 pounds of margin if the trailer is at its exact dry weight. Owners who carry more gear should consider reducing water to half-full or upgrading to a larger tow vehicle. Always weigh the loaded trailer at a certified scale to confirm you are under 5,500 pounds. Exceeding GVWR can cause tire blowouts, brake failure, and legal liability.
For those looking to reduce weight, swapping heavy items like propane tanks for lightweight composite ones or installing a composting toilet eliminates the need for a heavy black water tank.

What Do Owners Say About Towing the Beyond 22RB?
Owner reviews on forums like iRV2 and Forest River Forums consistently highlight a few key points. Many praise the 22RB’s stability at highway speeds, noting that it tracks well even in crosswinds when properly loaded. The torsion axle system earns positive comments for reducing road vibration inside the trailer, protecting dishes and electronics. However, a common complaint is that the OEM tires require frequent pressure checks because the small 15-inch wheels lose pressure more quickly than larger tires.
Owners also note that the factory-installed tire pressure monitoring system is a worthwhile upgrade. Those who tow with half-ton trucks (Ford F-150, Ram 1500) report no issues with power, but some with smaller SUVs (Jeep Grand Cherokee) find the 22RB pushes them around on steep grades. One owner stated: “The 22RB is light enough for my V6 Tacoma, but I wouldn’t want to tow it through the Rockies without a weight-distributing hitch.” Another said: “The Goodyear Endurance tires are great, but I check them every time I stop for gas because of the heat buildup in summer.”

Frequently Asked Questions
What is the maximum speed for towing the 22RB?
While tire ratings typically allow up to 75 mph, recommended towing speed for the 22RB with ST tires is 65 mph. Higher speeds increase heat buildup and risk of tire separation.
Can I use passenger car tires on this trailer?
No. Only use ST (Special Trailer) tires. Passenger car tires lack the sidewall strength needed to handle trailer loads and can fail catastrophically.
How do I adjust the brake controller for the 22RB?
Set the brake controller to apply 60% power to the trailer brakes initially. On a flat road, manually brake to test. If the trailer brakes grab too hard, reduce to 50%. Never exceed 80% to avoid locking the wheels.
What is the turning radius with the 22RB attached?
The 22RB has a 25-foot turning radius when attached to a standard pickup. Allow extra space when backing into campsites, as the rear overhang can swing wide.
Should I use a tire cover when storing the 22RB?
Yes. UV rays degrade tire rubber quickly. Use breathable tire covers (not plastic) when the trailer is stored outdoors for more than a week.
How often should I repack the wheel bearings?
Repack bearings every 12 months or 12,000 miles, whichever comes first. If you frequently tow through water crossings, repack every six months.
