1971 Dodge Pickup Tires

A 1971 Dodge Pickup can use G78-15, H78-15, 800-16.5, 875-16.5, 950-16.5, or 750-16, all in bias-ply construction. The correct size depends on whether the truck is a D100, D200, or D300, and in several D200 and D300 applications it also depends on the truck's GVWR grouping.

That means the first step is not choosing a brand or sidewall style, but confirming the exact truck configuration and wheel diameter. Many vintage pickups have had wheels changed over the years, so checking the installed rim before ordering is especially important when 16-inch and 16.5-inch fitments both appear within the same model family.

A 1971 Dodge Pickup can use 15-inch, 16-inch, or 16.5-inch rims, depending on the sub-model and load rating. D100 applications use 15-inch tire sizes, many D200 and D300 versions use 16.5-inch sizes, and one D300 4x2 GVWR 8000 application includes a 750-16 fitment for a 16-inch rim.

Rim diameter is the most important fitment check on this truck because a 16-inch tire and a 16.5-inch tire are not interchangeable. Before selecting any replacement, read the wheel stamp if available or measure carefully, then compare the tire's approved rim-width range when that specification is part of the tire you are considering.

The 1971 Dodge Pickup covers light-duty and heavier-duty versions under the same model name, so tire size changes with the truck's intended capacity. A D100 4x2 uses 15-inch alphanumeric bias-ply sizes, while D200 and D300 applications move into larger truck-oriented numeric sizes on 16-inch or 16.5-inch rims.

That variation keeps the page useful only if the exact sub-model is identified first. A tire that looks close in size may still be wrong for the wheel or the truck's load-carrying role, so matching the truck's designation, GVWR grouping, and actual wheels matters more here than it would on a single-fitment passenger car.

G78-15 is a bias-ply tire size on the 1971 Dodge Pickup. It is one of the 15-inch primary fitments used on the D100 4x2 and appears in both traditional whitewall passenger-style offerings and blackwall truck-oriented designs, depending on the tire series selected.

That matters because the original size designation does not automatically mean every G78-15 has the same visual character or use case. Some owners stay with bias-ply for period-style appearance, while others compare radial equivalents instead, but the wheel width, overall dimensions, and clearance should still be reviewed before changing construction.

For G78-15, radial equivalents include 205R15 as an 80-series metric radial, P215/75R15 as a 75-series P-metric radial, P225/70R15 as a 70-series P-metric radial, and 710R15 as a bias-look radial. For H78-15, the equivalents are 215R15, P225/75R15, P235/70R15, and 760R15 in those same categories.

Those options give a 1971 Dodge Pickup owner several ways to compare radial sizing, from more traditional metric proportions to lower-profile P-metric alternatives. A recommended 6-8 inch rim-width range is associated with these equivalents, but wheel compatibility, actual tire dimensions, and fender or steering clearance still need to be checked on the truck.

Start by confirming that the truck uses one of the 15-inch sizes with stated radial equivalents, because the available radial mappings here apply to G78-15 and H78-15. Then verify the wheel diameter, compare wheel width to the recommended range, and review the truck's available clearance at the fenders, steering stops, and suspension.

Construction changes can also alter the truck's look and driving feel, which matters on a restored or lightly used vintage pickup. A radial equivalent can be a useful alternative, but it should be treated as a fitment decision rather than an automatic swap, especially on a vehicle that may no longer have its original wheels.

Begin with the correct primary size for the truck's exact sub-model and wheel diameter, then narrow the choice by construction, sidewall style, and intended use. On this page, every primary fitment is bias-ply, but the product mix ranges from traditional whitewall designs to blackwall truck tires and heavy-duty commercial-style patterns.

Once the correct size is established, compare details that actually affect your truck setup, including rim-width compatibility, load figures where stated, and whether the tire's overall character suits restoration display, occasional road use, or working-truck duty. That approach is more useful than choosing by appearance alone on a pickup with several very different fitment paths.

The available sidewall styles for 1971 Dodge Pickup tires are primarily blackwall and wide whitewall, depending on size. The 15-inch G78-15 and H78-15 sizes include both blackwall and wide whitewall choices, while the 16.5-inch truck sizes are blackwall only. The 750-16 size includes both blackwall and wide whitewall offerings.

That split reflects the difference between lighter-duty, more appearance-conscious fitments and heavier truck-duty applications. A whitewall can support a more restoration-oriented presentation, while blackwall options usually align with utility or commercial character, but the sidewall style still has to be chosen within the correct size and wheel diameter for the truck.

Brands available for the 1971 Dodge Pickup include Coker Classic, STA, Firestone, Lester, and BFGoodrich. Brand choice depends heavily on size: 15-inch options include Coker Classic and STA, the 16.5-inch truck sizes are centered on STA, and 750-16 opens up the widest mix of brands and tire series.

The useful way to compare brands here is by what each one offers in the exact fitment your truck uses. Some emphasize wide whitewall period-style presentation, while others focus on truck, military, traction, or highway-oriented bias-ply patterns, so the better comparison is product character and specification rather than brand name alone.

A period-style choice starts with the truck's correct primary size and original-style bias-ply construction, then narrows by sidewall treatment and tread character. On a 1971 Dodge Pickup, that could mean a wide whitewall 15-inch or 16-inch bias-ply tire for a more styled presentation, or a blackwall truck tire for a more work-oriented vintage look.

The best appearance choice depends on how the truck is being presented rather than on one universal answer for every Dodge Pickup. If exact restoration authenticity matters, compare the tire choice against marque references, old photos, or build documentation, then make sure the selected tire still matches the truck's actual wheel diameter and use.

Tire construction has a visible effect on a restored 1971 Dodge Pickup because bias-ply tires tend to preserve the truck's period-style profile and presentation. That is especially relevant here since the primary fitments across the model range are bias-ply, with whitewall and blackwall choices shaping the finished look even further.

A radial equivalent on the 15-inch sizes may change the visual character even when the overall fitment goal stays close. Owners restoring a truck for show, display, or era-appropriate presentation often consider construction as part of the overall appearance, not just as a mechanical decision, so it deserves attention early in the selection process.

Yes, modifications can affect tire fitment on a 1971 Dodge Pickup, especially because this truck already spans 15-inch, 16-inch, and 16.5-inch wheel families from the factory fitment range. Aftermarket wheels, altered ride height, brake changes, or body modifications can all change the space available for the tire and the wheel-width requirements.

A truck that has been changed over the years should be checked as it sits now rather than judged only by model name. Measuring wheel diameter and width, confirming clearance at full steering lock, and looking for suspension or fender interference are sensible steps before mounting a replacement tire on any vintage pickup.

Before driving a 1971 Dodge Pickup on new tires, inspect the wheels for correct diameter and condition, make sure lug hardware and valve stems are in good shape, and confirm that the tires clear the fenders, suspension, and steering components. It is also wise to check inflation pressure, visible tread condition, and any signs of air loss after installation.

A vintage truck deserves a broader once-over before road use because old brake components, worn steering parts, or tired suspension pieces can affect how the new tires behave. A short, careful test drive followed by another inspection for rubbing, pressure change, or uneven seating is a practical way to catch issues early.

Collector-truck tires should be maintained with regular pressure checks, visual inspections, and attention to age-related deterioration even if the truck is driven only occasionally. On a 1971 Dodge Pickup, look for sidewall cracking, bulges, cuts, tread separation concerns, and slow air loss, especially after long storage periods or seasonal temperature changes.

Storage conditions matter almost as much as mileage on a vintage pickup. Keeping the truck away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and moving the vehicle periodically can reduce long-term flat spotting. Any tire that shows significant aging or damage should be evaluated before the truck returns to regular road use.
