1964 Oldsmobile Starfire Tires

The 1964 Oldsmobile Starfire uses three primary bias-ply tire sizes: 800-14, 850-14, and 900-14. All are 14-inch fitments, but the correct size depends on the car’s exact sub-model. The Coupe uses 800-14 and 850-14, while the Convertible uses 850-14 and 900-14.

That means the first step is identifying whether the car is a Coupe or Convertible, then confirming the wheel and current tire size already on the vehicle. A Starfire that has been restored, modified, or changed over to different wheels may not still carry its original-type setup, so size selection should start with the actual car in front of you.

The 1964 Oldsmobile Starfire uses 14-inch rims with its primary bias-ply tire sizes. That rim diameter is shared across 800-14, 850-14, and 900-14, so the wheel diameter remains consistent even though the tire sizes vary by sub-model and fitment combination.

Rim diameter alone does not settle the fitment question, because width and tire size still matter. It is smart to confirm the wheel stamp, measure the existing wheel if necessary, and compare the car’s current setup before choosing a replacement, especially if the Starfire has aftermarket wheels or a long-restored suspension and wheel package.

No. The 1964 Oldsmobile Starfire Coupe and Convertible share 850-14, but they do not use the exact same full set of primary sizes. The Coupe uses 800-14 and 850-14, while the Convertible uses 850-14 and 900-14, so fitment changes with the body style.

That overlap can create confusion if the car is missing its original tires or wheels. A buyer should verify the body style first, then confirm which size is actually on the vehicle and whether the wheel width matches the intended tire. That approach helps avoid choosing a larger or smaller primary size meant for a different Starfire configuration.

For the 1964 Oldsmobile Starfire, 850-14 is a primary bias-ply tire size. It belongs to the older numeric sizing system, where the leading number reflects nominal section width and the final number refers to the 14-inch rim diameter rather than a modern metric radial format.

That matters because choosing another 14-inch tire does not automatically preserve the same look or fitment behavior. Anyone considering a radial alternative should compare wheel width, overall tire dimensions, and clearance at the fender and steering components instead of assuming that any modern 14-inch radial will duplicate the original-style setup.

For 850-14, radial equivalents include 215R14, P225/75R14, and P235/70R14. For 800-14, the equivalents are 205R14, P215/75R14, P225/70R14, and 800R14 as a bias-look radial. These options span 80-series metric, 75-series P-metric, 70-series P-metric, and bias-look radial formats depending on the original size.

Those alternatives give a Starfire owner different ways to approach radial conversion while staying near the original fitment envelope. The recommended rim-width range is 5-7 inches for both equivalency groups, but wheel width, actual tire dimensions, and body clearance still need to be checked before moving from a primary bias-ply size to any radial alternative.

Start by matching the Starfire’s primary tire size to its actual radial-equivalent options rather than choosing a radial by rim diameter alone. Then confirm the wheel width, because the equivalent groups tied to 800-14 and 850-14 call for a 5-7 inch rim-width range. That keeps the conversion grounded in the correct size family.

A radial change should also be checked for fender clearance, steering clearance, and suspension condition, especially on a large 1960s car that may have been restored or modified over time. It also helps to decide whether the goal is a more modern radial driving feel or a more traditional appearance, since 800R14 offers a bias-look radial path.

Begin with the correct primary size for the car’s body style, since the 1964 Oldsmobile Starfire does not use one universal tire size across all configurations. All primary fitments are 14-inch bias-ply sizes, so the real selection process comes after size confirmation and includes sidewall appearance, available brands, tire series, and whether a radial equivalent is being considered.

A restoration-oriented car may call for a whitewall presentation that supports the Starfire’s upscale 1960s look, while a driver-focused car may lead you toward an equivalent radial where one exists. It also helps to compare rim-width compatibility and load figures where they are given, especially when choosing between 800-14, 850-14, and 900-14 product offerings.

Sidewall choices for the 1964 Oldsmobile Starfire include blackwall, narrow whitewall, and wide whitewall, depending on tire size. The broadest sidewall variety appears in 800-14, while 850-14 and 900-14 are available in narrow whitewall and wide whitewall forms within the applicable product lineup.

That sidewall choice has a major effect on how the car presents visually, especially on a full-size personal luxury model from the mid-1960s. A blackwall can create a cleaner and more understated look, while narrow and wide whitewalls move the car toward a stronger period-style appearance. The right choice depends on the Starfire’s restoration direction and overall wheel-and-trim presentation.

Available tires for the 1964 Oldsmobile Starfire come from BFGoodrich, Goodyear, and Universal Vintage Tire, depending on the size being considered. BFGoodrich covers all three primary sizes here, while Goodyear and Universal Vintage Tire appear in 800-14 options. Tire series also vary, including Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply.

Brand choice should be weighed alongside the exact size, sidewall treatment, and overall appearance you want for the car. Since not every brand appears in every Starfire size, the first filter remains correct fitment. After that, compare the available series and sidewall styles within that size rather than trying to choose a brand before the tire size has been settled.

A period-style 1964 Oldsmobile Starfire should start with the correct primary bias-ply size for the car’s sub-model: 800-14, 850-14, or 900-14. Staying with the proper 14-inch bias-ply format preserves the overall tire character that suits a full-size 1964 personal luxury car far better than jumping immediately to a modern-looking replacement.

From there, the visual decision usually comes down to sidewall treatment. Narrow whitewall and wide whitewall options are available across the applicable Starfire product range, and blackwall appears in 800-14. If exact originality matters beyond a general period-style look, compare your car against marque references, surviving examples, or restoration documentation before settling on a specific whitewall presentation.

Tire construction changes more than ride and handling; it also changes how a restored 1964 Oldsmobile Starfire looks at a glance. The car’s primary fitments are bias-ply, and that construction supports the tall, traditional visual profile expected on a 1960s full-size Oldsmobile, especially when paired with narrow or wide whitewall styling.

A radial equivalent can be a reasonable alternative for some owners, but it may present the car differently depending on the sizing format chosen. An 80-series metric radial generally keeps the look closer to the original tire envelope than a lower-profile 70-series P-metric option. That makes construction choice part of the restoration conversation, not just a road-use decision.

Yes. Modifications can change tire fitment on a 1964 Oldsmobile Starfire even when the tire size itself is one of the correct primary sizes. Aftermarket wheels, changed wheel widths, altered ride height, suspension work, or body modifications can all affect how an 800-14, 850-14, 900-14, or radial-equivalent alternative sits on the car.

A Starfire that no longer carries its original wheel setup should be measured rather than assumed. Check wheel diameter and width, then verify fender and steering clearance with the intended tire before use. That matters even more when moving to a radial equivalent, because the size may be comparable in category without automatically matching every wheel and body condition on the car.

Before driving a 1964 Oldsmobile Starfire on new tires, inspect the wheels for damage or distortion, confirm the wheel diameter and width, and make sure the tires are mounted in the correct size for the car’s body style. It is also wise to verify inflation, lug torque, and visual clearance around the fenders, suspension, and steering components.

A newly mounted tire does not eliminate older vehicle issues, especially on a collector-era Oldsmobile. Look over steering and suspension wear, check for rubbing during full-lock turns, and recheck pressure after the first drives. Those steps are especially important if the car has sat for long periods or if the wheel-and-tire package differs from the setup it carried in past years.

Collector-car tires on a 1964 Oldsmobile Starfire should be inspected regularly for air loss, sidewall cracking, cuts, bulges, and uneven tread wear. Keep inflation at the appropriate level for the tire in use, and pay attention to condition over time, since collector vehicles often accumulate age faster than mileage.

Storage conditions matter almost as much as road use. Tires last better when the car is kept away from prolonged sunlight, moisture, heat, and ozone-producing equipment such as electric motors or welders. A Starfire that is driven only occasionally also benefits from periodic movement and visual checks before each outing rather than waiting for an annual inspection.
