1981 Plymouth Trucks Arrow Pickup Tires

The 1981 Plymouth Trucks Arrow Pickup uses two different tire sizes depending on sub-model. The Base uses a 6.00-14 bias-ply tire, while the Sport uses a 185R14 radial tire. Both sizes are built around a 14-inch rim, but they are not the same fitment path.

The practical question is not just wheel diameter, but which version of the truck is being fitted and whether it still has its correct wheel setup. A Base restored around a traditional bias-ply presentation should be evaluated differently than a Sport using a radial size, especially if wheels or suspension have been changed over the years.

The 1981 Plymouth Trucks Arrow Pickup uses a 14-inch rim with both primary tire sizes. That applies to the 6.00-14 bias-ply fitment used on the Base and the 185R14 radial fitment used on the Sport, so rim diameter remains consistent even though the tire constructions differ.

Rim diameter is only one part of the fitment picture, so it helps to confirm wheel width as well before choosing a tire. That matters most on the Sport, where available 185R14 radial products have stated rim-width ranges, and it also matters on any truck that may have received aftermarket wheels during its working life.

More than one tire size appears because the 1981 Plymouth Trucks Arrow Pickup uses different fitments by sub-model. The Base is tied to a 6.00-14 bias-ply size, while the Sport uses a 185R14 radial. The difference is not just in sizing language, but also in construction type and tire character.

That split makes sub-model identification the first step before any purchase decision. Once that is settled, the next checks are whether the truck still carries its intended 14-inch wheels, whether the wheel width suits the tire being considered, and whether restoration appearance or regular road use is the higher priority.

On the 1981 Plymouth Trucks Arrow Pickup, 6.00-14 is the bias-ply fitment used on the Base sub-model. It follows the older numeric sizing system and represents a different construction approach than the 185R14 radial used on the Sport version of the truck.

That distinction matters because construction choice affects both appearance and how the truck is set up around the tire. Anyone working with a Base should confirm that the current wheels, stance, and intended use still match a bias-ply configuration rather than assuming any 14-inch tire will serve the same role.

The answer depends first on the truck's sub-model and current configuration. A 1981 Plymouth Trucks Arrow Pickup Base uses a 6.00-14 bias-ply fitment, while the Sport uses a 185R14 radial. Those are separate primary fitments, not simply two casual alternatives for the same setup.

Selection usually comes down to whether the truck is being kept close to its original-era construction style or equipped for the radial fitment associated with the Sport. Wheel width, suspension condition, and clearance should be checked carefully before changing construction, especially on older compact pickups that may have seen replacement wheels over time.

A conversion from the Base model's 6.00-14 bias-ply setup to a radial arrangement starts with verifying the actual wheel dimensions on the truck. Rim diameter alone is not enough, because radial fitment also needs suitable wheel width, along with enough room at the fenders, steering stops, and suspension points.

It also helps to look at the truck as a complete system rather than a tire size change alone. Ride height changes, replacement springs, aftermarket wheels, and alignment condition can all influence the result, so any radial alternative should be checked against the truck's real-world setup before assuming it will be a workable conversion.

Start with the exact sub-model, because the 1981 Plymouth Trucks Arrow Pickup does not use one universal tire size. The Base uses 6.00-14 bias-ply, while the Sport uses 185R14 radial. After that, the important factors are construction type, 14-inch wheel compatibility, intended appearance, and how the truck will actually be driven.

A restoration-minded Base owner may focus on preserving the traditional look and feel of a numeric bias-ply tire. A Sport owner choosing among 185R14 radials has more product-level decisions to make, such as blackwall versus narrow whitewall styling, tire series, and whether the wheel width falls within the stated range for the tire being considered.

For the 185R14 radial fitment used on the 1981 Plymouth Trucks Arrow Pickup Sport, both blackwall and narrow whitewall styles are available. That gives the truck owner a visible appearance choice without changing the basic radial size used by the Sport sub-model.

Sidewall style can change the truck's overall presentation more than many buyers expect, especially on a compact pickup with relatively simple body lines. A blackwall keeps the look understated, while a narrow whitewall adds a more dressed-up period flavor, so the right choice usually depends on whether the truck leans toward utility, preservation, or show-oriented styling.

In the 185R14 radial size used on the 1981 Plymouth Trucks Arrow Pickup Sport, available brands include Michelin, Phoenix, and Vredestein. Michelin appears in the MXV series, while Vredestein appears with the Sprint Classic, giving the buyer a few distinct product paths within the same basic size.

Brand choice should be weighed alongside the actual product details rather than treated as the whole decision. Sidewall style, tire series, rim-width specification, and the kind of appearance wanted for the truck all matter, especially since one 185R14 option may suit a cleaner blackwall presentation while another better supports a restoration-oriented whitewall look.

A period-style choice starts with the truck's actual sub-model. The Base uses a 6.00-14 bias-ply tire, which naturally supports an older light-truck appearance, while the Sport uses a 185R14 radial. Keeping those fitment paths separate is the best starting point for a convincing restoration-oriented result.

Construction and sidewall presentation both shape how authentic the truck feels visually. A buyer aiming for strict historical accuracy should compare the vehicle against marque references, surviving examples, or original ownership material, while someone pursuing a more era-appropriate look can focus on the correct size first and then choose the sidewall treatment that best suits the truck.

Tire construction changes the visual character of the 1981 Plymouth Trucks Arrow Pickup more than the size code alone suggests. A 6.00-14 bias-ply on the Base carries a more traditional vintage presentation, while the Sport's 185R14 radial looks more like the later compact-truck tire style associated with the early 1980s.

That means appearance decisions should be tied to the version of the truck being restored, not just to what happens to fit a 14-inch wheel. Sidewall style then becomes the finishing detail, particularly on the radial Sport fitment where blackwall and narrow whitewall choices can move the truck toward a cleaner utility look or a more dressed presentation.

Yes, modifications can change tire fitment on a 1981 Plymouth Trucks Arrow Pickup even when the truck still uses a 14-inch wheel. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or ride-height changes can all affect how a 6.00-14 bias-ply or 185R14 radial sits and clears.

A truck that has been lowered, lifted, or updated over the years should be measured as it stands now rather than treated like an untouched original. Steering clearance, inner-fender space, and the relationship between the tire and suspension components all deserve a look before settling on a tire simply because the nominal size appears correct.

Before putting a 1981 Plymouth Trucks Arrow Pickup back on the road, inspect the wheels, valve stems, and overall wheel condition along with the new tires themselves. Tire pressure, bead seating, visible clearance around the fenders and suspension, and the general condition of brakes, steering, and front-end components all deserve attention.

A short, careful test drive is a smart follow-up after installation. Any pull, rubbing, vibration, or unusual steering feel should be addressed early, especially on a collector-era compact pickup that may have older bushings, springs, or alignment settings affecting how the new tires behave once the truck is moving under real road load.

Collector-use tires on a 1981 Plymouth Trucks Arrow Pickup should be checked regularly for pressure loss, tread wear, sidewall cracking, bulges, and cuts, even if the truck is driven only occasionally. Low annual mileage does not prevent age-related deterioration, and older compact pickups often spend long periods parked between outings.

Storage conditions also matter. Keeping the truck away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and moving the vehicle periodically can reduce long-term stress in one contact area. Before any longer drive, it is worth rechecking pressure and giving the tires a close visual inspection rather than relying on appearance alone.
