1967 Pontiac Tires

The 1967 Pontiac uses two primary tire sizes: 855-14 and H78-14. Both are bias-ply sizes built for 14-inch rims, and both appear across the covered sub-models, including All Other Models, Wagon, and Wagon w/Disc Brakes.

That means the main fitment question is not usually which sub-model changes size, but which of the two period-style sizing formats and available tire looks best suits the car. Before choosing, confirm that the wheels on the car are still the correct 14-inch setup and have not been changed over the years.

The 1967 Pontiac uses a 14-inch rim with both of its primary tire sizes, 855-14 and H78-14. Even though the two sizes use different vintage sizing systems, they share the same basic wheel diameter.

Rim diameter is only part of the picture, especially on an older car that may have had wheels changed at some point. It is also worth checking actual wheel width before selecting a tire, since the available 855-14 and H78-14 products do not carry the same rim-width compatibility range.

The covered 1967 Pontiac sub-models all use the same pair of tire sizes: 855-14 and H78-14. That includes All Other Models, Wagon, and Wagon w/Disc Brakes, with bias-ply construction across the board.

Shared fitment makes the search easier, but it does not eliminate the need to inspect the car itself. An older Pontiac may still have replacement wheels, brake changes, or suspension work that affects clearance, so it is smart to verify the existing wheel and tire setup before choosing between the available vintage sizes.

For the 1967 Pontiac, 855-14 is a primary bias-ply tire size. It uses the older numeric sizing system and belongs to the traditional tire construction associated with full-size American cars of the period.

Keeping that bias-ply format tends to preserve the car’s vintage presentation, especially when whitewall styling matters to the overall look. If a radial alternative is being considered, compare the intended replacement against wheel width, overall fit on the 14-inch rim, and the vehicle’s available clearance rather than assuming any radial will behave the same way.

Radial equivalents for 855-14 include 215R14 as an 80-series metric radial, P225/75R14 as a 75-series P-metric radial, and P235/70R14 as a 70-series P-metric radial. A recommended rim-width range of 5 to 7 inches accompanies those equivalent choices.

Those sizes offer a useful comparison path for owners thinking about moving away from bias-ply construction while staying with a 14-inch fitment. The equivalent label does not remove the need to check wheel width, overall dimensions, and steering or fender clearance, especially on a car that may no longer be on its original wheel and suspension setup.

That decision depends on what matters most for the car. The 1967 Pontiac’s primary fitments are bias-ply sizes, 855-14 and H78-14, so a bias-ply tire is the natural starting point for a period-style appearance and original-format sizing.

A radial equivalent can still be considered, with 215R14, P225/75R14, and P235/70R14 available for either primary size. Owners should make the choice only after checking wheel width and vehicle clearance, and after deciding whether the priority is restoration-oriented presentation or a move toward a more modern tire construction.

Start with the correct primary fitment: 855-14 or H78-14, both in bias-ply construction on 14-inch rims. From there, the most important differences are sizing format, sidewall style, tire series, and the wheel-width range supported by the specific tire you are considering.

That matters because this car’s available products point in two different visual directions. The 855-14 options use narrow whitewalls in the BFGoodrich Silvertown Classic Bias Ply line, while H78-14 is offered as a wide whitewall in the Coker Classic Bias Ply line, so the right choice depends on both fitment and appearance goals.

The available sidewall styles for the 1967 Pontiac are narrow whitewall and wide whitewall. The 855-14 products use narrow whitewalls, while the H78-14 offering uses a wide whitewall, giving the buyer two distinct vintage presentations.

Sidewall choice can change the visual balance of a full-size Pontiac as much as the tire size itself. A narrower whitewall tends to keep the look more restrained, while a wider whitewall creates a stronger period-style statement, so it makes sense to compare the tire to the car’s trim, wheel covers, and restoration direction before deciding.

The available tires for the 1967 Pontiac come from BFGoodrich and Coker Classic. BFGoodrich covers the 855-14 size in the Silvertown Classic Bias Ply series, while Coker Classic offers an H78-14 option in the Coker Classic Bias Ply series.

Brand should be considered alongside the actual tire specification rather than by itself. For this car, the more meaningful comparison is how each brand’s available size lines up with the sidewall treatment you want, the wheel width on the car, and whether you are staying with one of the original-format bias-ply sizes.

A period-style approach starts with the 1967 Pontiac’s original-format bias-ply fitments, 855-14 or H78-14. Both preserve the proper vintage sizing language for the car, but they lead to different available product presentations and slightly different visual impressions.

Choosing between them usually comes down to how the finished car is meant to look. Narrow whitewall 855-14 options and a wide whitewall H78-14 option are both available, so owners focused on exact historical appearance should compare the tire choice with marque references, original photos, or restoration documentation for their particular car.

On a restored 1967 Pontiac, tire construction affects more than ride and handling feel; it also influences the car’s overall visual character. Bias-ply tires keep the vintage sizing and period-style presentation that many full-size American restorations are built around.

Switching to a radial equivalent can change the look even when the rim diameter stays the same, simply because the sizing convention and sidewall presentation differ from the original bias-ply format. Owners restoring for a traditional appearance often start with the primary bias-ply sizes, then weigh any radial change against appearance as carefully as fitment.

Yes, modifications can affect tire fitment on a 1967 Pontiac even when the correct original tire size is known. Wheel changes, altered wheel width, suspension work, brake conversions, lowering, or body adjustments can all influence how an 855-14, H78-14, or radial equivalent sits on the car.

That is why the actual wheel and chassis setup should be checked before choosing tires. A 14-inch diameter alone does not confirm compatibility, and changes to width or clearance can matter just as much, especially if the car has been updated over time or no longer carries its original wheels.

Before driving a 1967 Pontiac on new tires, inspect the wheels, valve stems, lug hardware, and basic suspension and steering condition. It also makes sense to confirm that the tires are mounted in the correct size for the car, inflated properly for the intended setup, and free from installation damage or obvious interference.

A short initial check drive is worthwhile on a collector-era car. Watch for rubbing during turns, unusual vibration, pull, or contact under suspension movement, then recheck air pressure and mounting condition after the first miles so any fitment issue is caught before regular road use.

Collector-car tires in 855-14 or H78-14 should be maintained with regular pressure checks, visual inspection, and attention to age-related condition. Even a lightly driven 1967 Pontiac can develop issues from long storage, including cracking, flat spotting, sidewall damage, or gradual air loss.

Storage conditions matter as much as mileage on a vintage Pontiac. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tires, and periodic inspection before each outing is a smart habit so cuts, bulges, or abnormal wear are found before they become road-use problems.
