How to Choose the Right Auto Tie-Down Strap for Car Hauling
How to Choose the Right Auto Tie-Down Strap for Car Hauling
Why Strap Selection Matters More Than Most Haulers Think
Most experienced auto haulers already know that a cargo strap from the hardware store is not the same as a purpose-built auto tie-down strap. But even within the category of auto-specific straps, the differences matter.
The wrong strap type can put lateral stress on a wheel well or axle that it isn't designed to handle, fail to seat properly in your ratchet, causing slippage under load, leave finish damage on custom rims or lowered vehicles, or create a DOT violation on a roadside inspection.
Working Load Limit (WLL) is the first number to understand. WLL is the maximum load a strap is rated to secure under normal conditions — it is not the breaking strength. Professional auto haulers generally use straps rated for 3,333 lbs WLL or higher per strap, with four-point tie-down systems covering most standard passenger vehicles. Always verify your setup against FMCSA cargo securement rules for vehicles (49 CFR Part 393, Subpart I).
The Main Types of Auto Tie-Down Straps — and When to Use Each
Axle Straps
Best for: Standard cars, trucks & SUVs on open carriersAxle straps loop around the axle of the vehicle and connect to your ratchet or anchor point. They're one of the most common strap types in auto transport because they work with a wide range of vehicles and don't touch painted surfaces or wheels.
A quality axle strap will have reinforced loop ends, a flat or coated surface where it contacts the axle to prevent abrasion, and a WLL appropriate for the vehicle weight. Avoid thin webbing that can bite into the axle under tension.
Shop Axle Straps →Lasso Straps
Best for: Lowered vehicles, sports cars, upper deck positionsLasso straps use a loop on one end that cinches around the tire. They're fast to deploy, work well on vehicles with limited axle clearance, and are popular on both open and enclosed carriers.
The loop end should tighten evenly around the tire without rolling or twisting. Look for heavy-duty stitching at the loop transition point — this is where lasso straps typically wear first.
Shop Lasso Straps →Over-Wheel Straps
Best for: Motorcycles, ATVs, wide-body tiresOver-wheel straps wrap over the top of the tire and secure to anchor points on both sides. They cradle the tire from above rather than looping around it, distributing force across a wider surface area.
Look for proper width to cover the tire tread without slipping off to the sidewall. Padding or a soft liner on the contact surface is a significant plus for protecting tires and wheels on custom builds.
Shop Over-Wheel Straps →V Bridle Straps
Best for: Front tie-down positions on open carriersA V bridle strap has a single ratchet hook on one end that splits into two legs, each attaching to a separate anchor point — forming a V shape. They provide two-point attachment from a single ratchet, giving you lateral stability without requiring two separate ratchet assemblies.
Ensure equal-length legs and quality snap hooks or flat hooks rated for your load. A poorly matched V bridle can pull unevenly and create lateral stress on the suspension.
Shop V Bridle Straps →Wheel Lift Straps
Best for: Tow truck wheel lift and underlift/overhook setupsWheel lift straps are specifically designed for tow truck operations where the front or rear wheels of a vehicle are lifted off the ground. They secure the tire to the wheel lift cross bar and keep the vehicle from bouncing off during transport.
These are not the same as general auto tie-down straps — they're purpose-built for the forces involved in towing with one axle lifted. Look for proper width for the tire contact patch, heavy-duty ratchet hardware, and a WLL that accounts for dynamic loading during towing. Cheap wheel lift straps are a serious safety risk in this application.
Shop Wheel Lift Straps →Tow Dolly Wheel Nets
Best for: Two-wheel towing on a tow dolly — mandatory safety equipmentTow dolly wheel nets hold the front wheels of a vehicle onto a tow dolly, preventing the tires from rolling off the side during transport. They work differently from straps — rather than tensioning against the vehicle, they cage the tire.
Look for a net that fits your dolly's ramp width and the tire sizes you typically haul. Adjustable models that can accommodate a range of tire widths are the most versatile for operators who haul a variety of vehicles.
Shop Tow Dolly Wheel Nets →Steering Wheel Straps
Best for: All open-carrier and enclosed-trailer transportSteering wheel straps lock the steering wheel in place during transport, preventing front wheels from turning and causing trailer sway. They're used in addition to tie-down straps, not instead of them. Standard practice on professional auto transport operations — don't load without one.
Shop Steering Wheel Straps →What to Check Before You Buy Any Auto Tie-Down Strap
Regardless of strap type, these factors determine whether a strap belongs on your trailer:
| What to Check | Why It Matters | What to Look For |
|---|---|---|
| WLL Rating Label | Required for DOT compliance; verifies load capacity | Clearly printed WLL on the strap itself — if it's missing, don't buy it |
| Webbing Width & Material | Affects surface protection and load distribution | Polyester webbing, 2"–4" wide; resists stretch better than nylon |
| Hook & Ratchet Quality | Hardware is where cheap straps fail first | Forged steel hooks, smooth ratchet action, operable release in cold weather |
| Application-Specific Build | Auto transport forces differ from generic cargo loads | Purpose-built for auto hauling — not repurposed flatbed or cargo straps |
Don't cut corners on hardware: A strap rated at 3,333 lbs WLL is only as strong as its weakest component. A $4 ratchet buckle will let you down before the webbing does. Buy complete assemblies from reputable brands — the few dollars saved on cheap hardware is not worth a vehicle off your trailer on the highway.
Build Your Complete Strap Kit
Most professional auto haulers run a combination of strap types depending on their trailer configuration and the vehicles they're hauling. A common open-carrier setup includes axle straps as the primary tie-down with V bridles at the front, plus steering wheel straps on every vehicle. GO-TOW.com carries complete strap kits so you can build out a full inventory from a single order.

Shop ProtectorsFrequently Asked Questions
What's the difference between an axle strap and a lasso strap?
An axle strap loops around the vehicle's axle — it doesn't contact the wheel or tire at all, which makes it ideal for standard vehicles with accessible axles. A lasso strap loops around the tire itself, which makes it faster to deploy and better suited for lowered vehicles, sports cars, or upper deck positions where reaching the axle isn't practical. Many professional haulers carry both and use whichever is more appropriate for each vehicle on the load.
How many straps do I need per vehicle for DOT compliance?
FMCSA regulations (49 CFR Part 393.116) generally require a minimum of four tie-down devices for a standard passenger vehicle — one at each wheel position or equivalent securement points. The specific requirement depends on vehicle weight and configuration. Always consult the current FMCSA cargo securement standards and your state's DOT regulations, as requirements can vary. When in doubt, four-point securement is the professional standard in auto transport.
Can I use the same straps for both open carrier and tow truck operations?
Some strap types overlap — axle straps and lasso straps work in both applications. However, wheel lift straps are specifically engineered for the dynamic load forces in tow truck wheel lift operations and should not be substituted with general auto transport straps. Similarly, tow dolly wheel nets are purpose-built for dolly use and don't have an equivalent in open carrier setups. Buy the right tool for each application rather than improvising with what's on hand.
What's the WLL I should be running for standard passenger cars?
Most professional auto haulers use straps rated at 3,333 lbs WLL per strap in a four-point system, which provides adequate securement for standard passenger vehicles. For heavier vehicles — full-size trucks, large SUVs, or commercial vehicles — you may need higher WLL ratings. Always match your strap WLL to the weight of the vehicles you're hauling and verify compliance with FMCSA requirements. The WLL label must be present and legible on every strap you use commercially.
How often should I replace my auto tie-down straps?
Replace immediately if you find any cut, nick, or abrasion that breaks the webbing weave — or if a strap was involved in a sudden-stop event or accident, even if it looks intact. For straps that pass visual inspection, most manufacturers recommend retirement after 3–5 years of regular use regardless of visible condition. High-volume operations (hauling daily) should inspect more frequently and replace sooner. Keep a set of spares on the truck so a failed strap found at pre-trip doesn't kill your schedule.
