1964 Pontiac Tempest Tires

The 1964 Pontiac Tempest uses three primary bias-ply tire sizes: 6.50-14, 700-14, and 750-14. The exact size depends on the sub-model, with 6-cylinder, 8-cylinder, and wagon versions not all sharing the same fitment. Every primary size for this Tempest uses a 14-inch rim.

That means the first step is identifying the exact Tempest configuration before choosing a tire. Even though all of the sizes share the same rim diameter, the size itself still affects the car’s stance, appearance, and available product choices. If the car has been modified or is wearing replacement wheels, compare the current wheel and tire setup carefully before moving forward.

The covered 1964 Pontiac Tempest tire sizes all use a 14-inch rim diameter. That applies to 6.50-14, 700-14, and 750-14, so the wheel diameter remains consistent even though the tire sizes vary across the model range.

Rim diameter is only part of the fitment picture, so it should not be treated as the only thing to confirm. Wheel width also matters, especially if you are comparing different products or looking at a radial equivalent for 700-14 or 750-14. A Tempest with aftermarket wheels, brake changes, or suspension alterations deserves an extra clearance and wheel-specification check before selecting tires.

The 1964 Pontiac Tempest has more than one tire size because different sub-models use different primary fitments. Across the range, 6.50-14, 700-14, and 750-14 all appear, with some overlap between 6-cylinder, 8-cylinder, and wagon versions rather than one universal size for every car.

That variation means a buyer should not choose by year and model name alone. The exact sub-model narrows the correct size range, and the car’s current wheel setup should still be checked if it has been changed over time. Once the fitment is confirmed, the remaining decisions are mostly about appearance, available product choices, and whether a radial-equivalent option is worth considering.

For the 1964 Pontiac Tempest, 700-14 is a primary bias-ply tire size. It uses a vintage numeric size format and remains the original-style construction choice for Tempest applications that call for that size rather than a modern radial as the primary fitment.

A radial can still be considered, but that becomes an equivalent-size decision rather than the original fitment type. For 700-14, the radial alternatives use different sizing conventions, so the owner should compare wheel width, overall dimensions, and clearance before making a change. That is especially important on an older car where wheels, ride height, and suspension condition may no longer match original specifications.

For 700-14, radial equivalents include 185R14, P195/75R14, and P205/70R14. For 750-14, radial equivalents include 195R14, P205/75R14, P215/70R14, and 750R14, with 750R14 serving as the bias-look radial option in that group.

These alternatives give a Tempest owner different ways to move from vintage numeric sizing into metric, P-metric, or bias-look radial territory. The recommended rim-width range for those equivalent groupings is 4-6 inches, but wheel width alone does not settle the question. Clearance around the fenders and suspension, along with the car’s intended use and desired appearance, should be checked before making the switch.

That depends on what matters most for the car. The primary fitments for the 1964 Pontiac Tempest are bias-ply sizes, so staying with bias-ply keeps the car in its original tire-sizing and construction style. Radial equivalents are available for 700-14 and 750-14 if a different construction is being considered.

The practical choice usually comes down to restoration priorities, tire appearance, and how the Tempest will be driven. A buyer focused on a period-style presentation may prefer the original bias-ply format, while someone considering regular road use may want to study the radial-equivalent options more closely. Either way, the wheel dimensions and vehicle clearances should be verified before changing construction.

Start with the correct primary size for the exact 1964 Pontiac Tempest sub-model, since this car can use 6.50-14, 700-14, or 750-14 depending on configuration. After size is confirmed, the main considerations are whether to stay with bias-ply construction, what sidewall style suits the car, and which tire series best matches the intended look.

A practical comparison should also include wheel compatibility and the available product specifications within the chosen size. On 700-14 and 750-14, the selection can involve blackwall, narrow whitewall, wide whitewall, or redline treatments, plus several brand and series differences. That makes appearance and setup just as important as the size code itself when narrowing the final choice.

Sidewall choices for the 1964 Pontiac Tempest include blackwall, narrow whitewall, wide whitewall, and redline, depending on the tire size selected. The broadest variety appears in 750-14, while 700-14 is available in blackwall and narrow whitewall form.

That sidewall choice has a major effect on how the car presents visually, especially on a mid-1960s Pontiac. A blackwall keeps the look restrained, whitewalls create a more traditional dressed appearance, and redline offers a distinctly performance-oriented period style. The right decision depends on the exact Tempest configuration, the owner’s restoration direction, and the tire size the car actually uses.

Available 1964 Pontiac Tempest tire brands include BFGoodrich, US Royal, Coker Classic, Firestone, Universal Vintage Tire, and Goodyear. Brand variety is especially strong in 750-14, where multiple sidewall treatments and series are available across several traditional bias-ply offerings.

Brand should be compared alongside the tire’s size, series, sidewall style, and wheel compatibility rather than treated as the only decision point. Some buyers will narrow the field by the look they want, such as blackwall, narrow whitewall, wide whitewall, or redline. Others may focus first on staying within the right rim-width range for the wheels already on the car.

A period-style 1964 Pontiac Tempest usually starts with the correct primary bias-ply size for the exact sub-model, whether that is 6.50-14, 700-14, or 750-14. From there, the appearance decision often shifts to sidewall treatment, since blackwall, narrow whitewall, wide whitewall, and redline options can create very different visual results.

For a restoration-oriented car, matching the tire’s overall look to the way the Tempest is being finished is just as important as choosing the right size. If exact originality matters beyond general period style, the safest approach is to compare the car against marque references, historical photos, and vehicle-specific documentation. That keeps appearance choices grounded while still using the correct fitment range.

Tire construction changes the visual character of a restored 1964 Pontiac Tempest because bias-ply tires preserve the original-style sizing language and sidewall presentation of the era. Since the Tempest’s primary fitments are bias-ply, staying with that construction maintains the most traditional look before sidewall style is even considered.

A radial equivalent can change the presentation by moving the car into metric or P-metric sizing, even when the overall intent remains vintage. That does not make the result wrong, but it does make the tire choice part of the restoration story rather than a simple mechanical decision. Owners balancing road use and appearance should decide which matters more before changing construction.

Yes, modifications can affect tire fitment on a 1964 Pontiac Tempest even when the original tire size is known. Changes to wheel width, wheel offset, ride height, suspension components, or body clearance can all influence whether a bias-ply size or radial equivalent works comfortably on the car.

That matters because the Tempest already has more than one primary tire size across its sub-model range, so a modified car may no longer reflect the original setup. A buyer should check the actual wheel dimensions, inspect clearance at full steering travel, and confirm space around the fenders and suspension. Those checks become even more important when moving away from the original bias-ply construction.

Before driving a 1964 Pontiac Tempest on new tires, inspect the wheels for correct diameter and condition, confirm the wheel width is appropriate for the chosen tire, and make sure the tires are inflated properly. It is also wise to check for suspension wear, alignment issues, and any interference points around the fenders or steering components.

Older collector cars deserve a careful walk-around even when the tires are brand new. Look for rubbing at full lock, confirm lug hardware is secure, and recheck tire pressure after the first short drive. If the Tempest has been sitting for long periods or has received replacement wheels over the years, a more complete inspection helps prevent a simple fitment mismatch from becoming a road-use problem.

Collector-car tire maintenance for a 1964 Pontiac Tempest starts with regular pressure checks, visual inspections, and attention to age as well as tread condition. Tires on low-mileage cars can still deteriorate from time, storage conditions, sunlight, ozone exposure, and long periods of sitting even when they do not show heavy wear.

A good routine includes checking for sidewall cracking, bulges, cuts, flat spotting, and slow air loss before the car goes back on the road. Storage also matters, so the Tempest should be kept away from prolonged heat, moisture, and direct sunlight when possible. Periodic inspection is especially important on a vintage car where road use may be infrequent but expectations for safe, smooth operation remain high.
