1964 Pontiac Tire Fitment Guide

1964 Pontiac vehicles use five tire sizes across three model lines: 750-14 on the GTO and some Tempest applications, 800-14 and 850-14 on full-size Pontiac models, and 6.50-14 plus 700-14 on Tempest applications. Every one of those sizes mounts on a 14-inch wheel. Rim width ranges are available for 700-14 at 5.00 to 5.50 inches, 750-14 at 5.00 to 5.50 inches, 800-14 at 5.00 to 6.00 inches, and 850-14 at 5.50 to 6.00 inches.

That means the first fitment question on a 1964 Pontiac is not wheel diameter, but model identification. A GTO owner has a narrower path than a Tempest owner, while a full-size Pontiac owner must confirm whether the car takes the 800-14 or 850-14 family. Once the model is pinned down, the next choice is usually sidewall appearance rather than construction, since these are all bias-ply offerings.

On a 1964 Pontiac, 750-14 is a numeric bias-ply tire size. The 7.50 figure refers to the nominal section width in inches, while the 14 refers to the wheel diameter in inches. In this year and make, that size appears on the GTO and on certain Tempest applications, and it is offered with narrow whitewall, wide whitewall, and redline sidewall styles.

For a buyer, the important takeaway is that 750-14 is not a modern metric radial code and should be matched to the proper 14-inch wheel and correct model usage. If your 1964 Pontiac is a GTO, this is the main fitment path. If your car is a Tempest, 750-14 is only one of several possible sizes, so the exact model configuration still needs to be confirmed before choosing a tire.

No, 1964 Pontiac models do not all use the same tire size. The GTO uses 750-14, the full-size Pontiac models use 800-14 or 850-14, and the Tempest range uses 6.50-14, 700-14, or 750-14 depending on application. All of those are bias-ply 14-inch fitments, but the size itself changes with the model family.

That model-to-model variation is why a year-and-make search is only the starting point for 1964 Pontiac tire selection. Choosing by appearance alone can lead you toward a tire that looks right for the era but belongs to a different part of the lineup. Confirming whether you have a GTO, a Tempest, or a full-size Pontiac keeps the selection historically appropriate and physically aligned with the intended wheel width range.

1964 Pontiac tires are available in several period-correct sidewall styles depending on size. The 750-14 offers narrow whitewall, wide whitewall, and redline choices; 800-14 offers blackwall, narrow whitewall, and wide whitewall; 850-14 offers narrow and wide whitewall; and 700-14 offers blackwall and narrow whitewall. Those differences matter because sidewall style has a major effect on how a restored Pontiac presents visually.

A GTO owner may lean toward redlines or a restrained whitewall depending on the look being recreated, while a full-size 1964 Pontiac often suits a broader whitewall treatment. Tempest buyers usually choose between a simpler blackwall or a narrower whitewall appearance. If show accuracy matters, compare your car against period photos, factory literature, and marque-club guidance before settling on sidewall style.

1964 Pontiac tire coverage comes from several heritage-oriented brands, with availability varying by size. The 750-14 is available from BFGoodrich, US Royal, and Coker Classic. The 800-14 is available from BFGoodrich and Universal Vintage Tire. The 850-14 and 700-14 sizes are available from BFGoodrich within the current range for this year and make.

Brand choice on a 1964 Pontiac usually comes down to the size your model requires and the sidewall style you want to present on the car. A buyer searching for redlines, for example, has a different path than someone looking for a blackwall or a wide whitewall. Once the correct size is confirmed, compare the available brands within that size rather than trying to force a preferred brand into a different fitment.

Within the 750-14 size for a 1964 Pontiac, BFGoodrich and US Royal share the same 14-inch rim diameter and the same 5.00 to 5.50 inch rim-width range, but they differ in sidewall offerings and load figures. BFGoodrich appears in narrow whitewall form at 1580 pounds at 32 psi, while US Royal appears in narrow whitewall and redline forms at 1500 pounds at 32 psi. Weight also varies slightly, with BFGoodrich at 23 pounds and US Royal at 22 pounds in the examples here.

That means the choice is less about basic fitment and more about the look and specification you want on the car. A buyer chasing a period redline presentation for a 1964 Pontiac GTO will naturally look in a different direction than someone restoring a quieter whitewall appearance. Compare the sidewall style first, then verify the tire’s marked specifications against the wheel and the intended use of the car.

Rim width requirements for 1964 Pontiac tires vary by size even though every fitment here uses a 14-inch wheel. The 700-14 and 750-14 sizes fit 5.00 to 5.50 inch rims, the 800-14 fits 5.00 to 6.00 inch rims, and the 850-14 fits 5.50 to 6.00 inch rims. Those ranges matter because a tire that fits the correct wheel diameter can still be mismatched to the wheel’s width.

When working with original 1964 Pontiac wheels, confirm the wheel width before ordering, especially if the car has changed hands or has been restored over time. Full-size Pontiac applications move into wider recommended rim ranges than the smaller Tempest fitments. Matching the tire to both diameter and width helps preserve the intended stance, tread profile, and steering feel of a period-style bias-ply setup.

Original 1964 Pontiac wheels can often be used with the tire sizes that belong to the correct model because every size here mounts on a 14-inch rim. That shared diameter means the larger fitment question is wheel width, not wheel diameter. The 700-14 and 750-14 sizes suit 5.00 to 5.50 inch rims, while 800-14 and 850-14 move into broader ranges up to 6.00 inches depending on size.

In practical terms, that makes wheel compatibility a model-by-model issue rather than a blanket yes or no for all 1964 Pontiac vehicles. A Tempest wheel and a full-size Pontiac wheel may both be 14-inch pieces, but they should still be checked against the tire’s rim-width range before reuse. If the car has replacement wheels of unknown origin, measuring the wheel is smarter than assuming it matches the original factory setup.

A 1964 Pontiac should be stored in a cool, dry, dark place with the tires kept away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment. Because these fitments are bias-ply tires, long static storage can encourage flat-spotting more readily than many later radial designs. Keeping the tires properly inflated during storage also helps them hold their shape.

If the car will sit for extended periods, rolling it occasionally or supporting it in a way that reduces prolonged loading can help protect the carcass. Clean, dry floors are preferable to damp ground, and indoor storage is far better than leaving a collector Pontiac outside under fluctuating weather. Good storage habits preserve both the look of the sidewalls and the driving behavior you expect when the car goes back on the road.

Tire life on a 1964 Pontiac is usually judged by age and condition more than by mileage, especially on collector cars that are driven only occasionally. A sensible rule is to inspect them closely once they reach the five- to seven-year range and to treat about ten years from the date code as the point where replacement deserves serious consideration, even if the tread still looks usable. Sidewall cracking, hardening, or deformation matters more than odometer totals on a hobby car.

That approach is especially important with bias-ply tires on a 1964 Pontiac because a car can appear fresh cosmetically while the tire structure has aged quietly in storage. Checking the date code, watching for weather checking, and paying attention to ride changes will tell you more than tread depth alone. If the car spends most of its time parked, age should lead your maintenance decisions.

Tires on a 1964 Pontiac should be inspected before every drive, and they deserve a more thorough check before any extended outing. Look for sidewall cracking, cuts, bulges, irregular wear, and pressure loss. Since these are collector-car bias-ply fitments, changes in shape after storage and visible aging on whitewalls, redlines, or blackwalls should be taken seriously rather than dismissed as cosmetic.

A quick pre-drive walkaround can prevent a small issue from becoming a roadside problem. Before a longer trip, inspect the spare as well and verify that valve stems are in good condition. On an older Pontiac, tire condition is only one part of the check, but it is one of the easiest and most important things to review before trusting the car at speed or far from home.

The 1964 Pontiac GTO belongs to an era when bias-ply tires were the original factory-type construction, and the fitment here centers on 750-14. That makes a 750-14 bias-ply tire the right starting point for an authentic 1964 Pontiac GTO restoration. Sidewall appearance can still vary within that size, including whitewall and redline presentations, so originality often comes down to the exact look your car carried when new.

For a judged restoration, construction type, size, and sidewall treatment all matter. If your goal is factory-style accuracy, use period literature, original photos, and Pontiac marque specialists to confirm the exact presentation for your car’s market and build. Avoid assuming that every 1964 GTO wore the same sidewall treatment, even when the base tire size itself is correct.

Correct tire fitment absolutely matters when showing a 1964 Pontiac, especially in classes that emphasize factory appearance. Judges and knowledgeable enthusiasts often notice whether the size suits the model, whether the construction matches the era, and whether the sidewall treatment fits the car’s original presentation. A full-size Pontiac wearing a compact Tempest size, or a sidewall style that clashes with the restoration theme, can look immediately out of place.

That does not mean every event uses the same standard, but it does mean tire choice should be treated as part of the restoration rather than an afterthought. If the car is headed for concours-style judging, verify the expected size and sidewall look with the hosting club or Pontiac specialists. Matching the tire visually and dimensionally to the car helps the whole restoration read as coherent and correct.

For a 1964 Pontiac using 800-14 tires, BFGoodrich and Universal Vintage Tire share the same 14-inch wheel diameter and both stay within the bias-ply, full-size Pontiac category, but they differ in available sidewall styles and published specifications. BFGoodrich appears in blackwall, narrow whitewall, and wide whitewall forms, with a 1620-pound load figure at 32 psi on the examples here and a 5.00 to 6.00 inch rim-width range. Universal Vintage Tire appears in a wide whitewall version for the same size.

That makes the decision largely about the appearance you want and how closely you want to tailor the tire to the car’s restoration theme. A buyer seeking a blackwall or narrow whitewall full-size 1964 Pontiac look will follow a different path than one committed to a broad whitewall presentation. Compare the sidewall style first, then confirm wheel width and the tire’s marked specifications before final selection.

1964 Pontiac tire choices here are all bias-ply designs, and no speed-rating letters are shown for these sizes in the current range. That means highway use should be approached with the expectations appropriate to a period-style collector tire and an early-1960s vehicle. On many 1964 Pontiac cars, the age of the suspension, steering, brakes, and overall mechanical condition is often just as important to real-world road safety as the tire itself.

A properly selected, correctly mounted, and well-maintained bias-ply tire can be entirely appropriate for normal collector-car driving, but it should not be treated like a modern high-speed touring tire. Before regular highway use, confirm condition, age, and inflation, and make sure the rest of the car is sorted to the same standard. A 1964 Pontiac in good mechanical order will usually tell you more about its comfort zone than a simple highway-speed assumption will.

Inflation pressure on a 1964 Pontiac should start with the vehicle manufacturer’s recommendation for the specific model, then be checked against the tire’s own marked load and pressure information. The tires here show load figures at 32 psi, including 1360 pounds for 700-14, 1500 to 1580 pounds for 750-14 depending on product, 1620 pounds for 800-14, and 1740 pounds for 850-14. Those numbers describe the tire’s load capacity at that pressure, not a one-pressure-fits-all instruction for every 1964 Pontiac.

The practical rule is not to transfer a pressure from one size or model to another simply because all of them use 14-inch wheels. A Tempest, a GTO, and a full-size Pontiac can place very different demands on their tires. Use the owner’s manual or factory tire placard as the first reference for the car, then confirm that the selected reproduction tire’s pressure and load information aligns with that application.

Before a longer drive in a 1964 Pontiac, inspect each tire for cracking, cuts, bulges, embedded debris, uneven wear, and proper inflation. Also check the spare, make sure the sidewalls are free from obvious age-related deterioration, and verify that the tires suit the wheel width range for the size being used. On a collector Pontiac, that tire check should happen alongside the usual review of brakes, fluids, cooling, lights, and steering components.

A bias-ply tire that looks acceptable at a glance can still reveal age, flat-spotting, or air-loss issues once the car has been sitting. A careful inspection before departure reduces the odds of chasing vibrations or roadside trouble miles from home. If the car has recently come out of storage, give it an even closer look and take a short local drive first before committing to a longer trip.
