1964 Buick Tire Fitment Guide

1964 Buick vehicles use six bias-ply sizes across five model lines: 800-15 for Electra 225, LeSabre, and Wildcat; 710-15 for LeSabre and Riviera; 760-15 for LeSabre, Riviera, and Wildcat; and 6.50-14, 700-14, or 750-14 for the Special. The full-size Buick models stay on 15-inch rims, while the Special uses 14-inch rims. Rim-width guidance appears for several sizes as well, including 5.00 to 5.50 inches for 700-14 and 750-14, 5.00 to 5.50 inches for 710-15, 5.50 to 6.00 inches for 760-15, and 6.00 to 6.50 inches for 800-15.

That means the first checkpoint on a 1964 Buick is always the model, followed by the actual wheel diameter on the car. A Special owner should stay within the 14-inch family, while Riviera, LeSabre, Wildcat, and Electra 225 owners need to remain in the 15-inch group that matches their application. If the car has been restored or modified over the years, compare the wheel and any old tire markings before choosing a replacement.

On a 1964 Buick, 800-15 is a numeric bias-ply size. The 800 portion is the nominal section-width code used in period sizing, and the 15 identifies a 15-inch wheel diameter. In this Buick lineup, 800-15 appears on the Electra 225, some LeSabre applications, and some Wildcat applications, all of them full-size cars rather than the compact Special.

For a buyer, the key point is that 800-15 is not a modern metric size and should be treated as a period-correct bias-ply fitment. It also carries a wider rim-width range than the smaller full-size Buick sizes, with products built for 6.00- to 6.50-inch rims. That makes it especially important to verify the actual wheel before ordering, particularly on cars that may have received swapped wheels during restoration or decades of service.

No, 1964 Buick models do not all use the same tire size. The Special stands apart with 14-inch sizes, while the LeSabre, Riviera, Wildcat, and Electra 225 use 15-inch sizes. Even within the 15-inch group, Buick did not use one universal fitment across the line: LeSabre spans 710-15, 760-15, and 800-15, Riviera uses 710-15 and 760-15, Wildcat uses 760-15 and 800-15, and Electra 225 stays with 800-15.

That variation matters because a buyer cannot rely on year and make alone for a 1964 Buick. If you know the model, you can quickly narrow the field; if you do not, the tire size itself becomes much harder to sort out. Owners of LeSabres in particular should verify the exact application on the car, because that model touches more than one 15-inch size and overlaps with several other Buick lines.

1964 Buick tires are available in several sidewall styles depending on size. 800-15 comes in wide whitewall, 710-15 in blackwall and wide whitewall, 760-15 in narrow whitewall and wide whitewall, 700-14 in blackwall and narrow whitewall, and 750-14 in narrow whitewall, wide whitewall, and redline. Every one of those offerings remains within a period-correct bias-ply construction, so the visual choice is mainly about the era look you want rather than switching to a different tire type.

For most 1964 Buick restorations, whitewall choices will feel the most natural, especially on Buick’s full-size and luxury-leaning models. Blackwalls can suit plainer presentations, while redlines on 750-14 give Special owners a distinctly mid-1960s performance-flavored appearance. Matching the sidewall style to the car’s trim level, restoration theme, and market presentation is often just as important visually as selecting the right size itself.

Several brands cover 1964 Buick tire sizes, depending on the exact fitment. Coker Classic supplies 800-15, while 710-15 is available from BFGoodrich and Firestone. The 760-15 size is offered by BFGoodrich, Coker Classic, and Universal Vintage Tire, 700-14 is available from BFGoodrich, and 750-14 comes from BFGoodrich, US Royal, and Coker Classic. All of these offerings stay within the bias-ply character expected for the period Buick market.

Brand choice on a 1964 Buick often comes down to which size your model uses and what visual details matter most to you. Some sizes have only one brand family behind them, while others open up more flexibility in sidewall treatment and presentation. If you are trying to match a restoration theme closely, compare both the brand and the sidewall style within the exact size your Buick requires instead of cross-shopping by brand alone.

For a 1964 Buick using 750-14 tires, 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 presentation and load rating. BFGoodrich appears in narrow whitewall form at 1580 pounds at 32 psi, while US Royal appears as a narrow whitewall and a redline at 1500 pounds at 32 psi. Both stay true to the same basic bias-ply fitment format for the Special.

That makes the decision less about raw fitment and more about appearance and restoration direction. If a buyer wants a higher stated load figure within the examples available, the BFGoodrich version stands out; if the goal is a redline look with strong mid-1960s flavor, the US Royal option becomes especially appealing. Either way, the exact wheel width and the visual style of the car should drive the final choice.

Rim-width guidance for 1964 Buick tires varies by size. The 700-14 and 750-14 sizes fit 5.00- to 5.50-inch rims, 710-15 also fits 5.00- to 5.50-inch rims, 760-15 fits 5.50- to 6.00-inch rims, and 800-15 fits 6.00- to 6.50-inch rims. Those ranges track the progression from the compact Special’s 14-inch fitments into the broader 15-inch tires used on Buick’s larger cars.

That spread is why wheel confirmation matters before replacing tires on a 1964 Buick, especially if the car’s history includes wheel changes. A 15-inch wheel alone is not enough information, because 710-15, 760-15, and 800-15 do not share the same rim-width range. Checking the wheel and matching it to the correct tire range helps preserve proper tire shape and keeps the finished stance closer to the car’s intended look.

Original 1964 Buick wheels cannot be treated as universal across all six sizes because the lineup splits between 14-inch and 15-inch fitments, and the supported rim-width ranges also vary. The Special’s 6.50-14, 700-14, and 750-14 sizes belong to 14-inch wheels, while 710-15, 760-15, and 800-15 belong to 15-inch wheels used on Buick’s larger models. Even among the 15-inch tires, the narrower 710-15 and the larger 800-15 are intended for different width ranges.

In practical terms, an original wheel can usually stay in service only when the replacement tire matches both its diameter and its width range. That matters most on cars that have passed through several owners, because wheel swaps are common on older Buicks. If you are moving between available sizes for the same model family, confirm the wheel itself first rather than assuming every full-size Buick wheel can accept every full-size Buick tire.

A 1964 Buick should be stored in a cool, dry, dark place with the tires kept away from direct sunlight, electric motors, furnaces, battery chargers, and other ozone-producing equipment. Because every tire size used here is bias-ply, long static storage can encourage flat-spotting more readily than many owners expect, especially on heavier full-size Buicks. Clean floors, stable temperatures, and proper inflation all help protect the casing and sidewalls during downtime.

If the car sits for extended periods, roll it periodically or support it in a way that reduces constant loading on one contact patch. That is especially helpful on Electra 225, Wildcat, and LeSabre models, where curb weight can work against a bias-ply tire during long storage. A breathable indoor cover and simple monthly checks go a long way toward keeping a collector Buick ready for the next drive.

On a low-use collector car such as a 1964 Buick, tire age usually matters more than tread wear. A sensible rule is to begin evaluating tires closely once they are around five to seven years old and to treat the ten-year mark as a strong replacement consideration, even if the tread still looks presentable. The DOT date code on the tire helps establish age, and that date matters just as much on bias-ply collector tires as it does on modern drivers.

Many vintage Buicks accumulate very few miles, so an old tire can look usable while quietly aging out. Sidewall checking, stiffness, recurring air loss, and changes in ride feel are all reasons to inspect more closely before another season of use. If the car’s history is uncertain, start with the date code and condition review rather than judging service life by odometer reading alone.

Tires on a 1964 Buick should be inspected before every drive and again before any extended outing or highway trip. Look for sidewall cracking, cuts, bulges, uneven tread wear, and signs that a tire is losing pressure between uses. Bias-ply tires also reward closer attention to how the car sits after storage, since flat-spotting or age-related stiffness may show up before the car has traveled very far.

A quick inspection is one of the simplest habits that protects both the car and the trip. On an older Buick, tire condition should be checked alongside brake feel, fluid levels, and steering response rather than as a separate task. If the spare is still carried for touring events, inspect that tire too, because an aged spare is often overlooked until it is urgently needed.

A 1964 Buick Electra 225 belongs to an era when bias-ply tires were still the normal original-equipment construction for American passenger cars, and the Electra 225 uses the 800-15 size within this Buick range. That makes a bias-ply 800-15 the natural starting point for an owner pursuing factory-style fitment on Buick’s flagship model. Sidewall treatment can still vary within that size, so the exact presentation may depend on the car’s trim, market, and restoration target.

For a judged restoration, staying with the correct construction type and size is usually the first priority. If you are chasing assembly-line-level accuracy, check period sales literature, dealer photography, and Buick marque clubs for trim-specific whitewall treatment rather than assuming every Electra 225 wore the same sidewall. That approach keeps the tire choice aligned with the car’s actual presentation instead of a broad year-only assumption.

Correct tire fitment absolutely matters when showing a 1964 Buick, especially in classes that value authenticity. Judges and experienced marque enthusiasts pay attention to size, construction type, and sidewall style because those details affect the car’s stance and period appearance. On a Buick of this era, using a wrong wheel diameter, the wrong numeric size family, or an obviously mismatched sidewall treatment can distract from an otherwise careful restoration.

The level of scrutiny depends on the event, but tire details are among the easiest authenticity cues to spot from a distance. A Special wearing the wrong 15-inch fitment or a full-size Buick carrying a look that clashes with its luxury presentation can stand out quickly. If your 1964 Buick is being prepared for serious judging, compare your tire choice against marque-club guidance and period imagery before the show season begins.

For a 1964 Buick in 760-15, Coker Classic and BFGoodrich share the same basic bias-ply size and 15-inch rim diameter, and both reach 1710 pounds at 32 psi in load-rated examples with a 5.50- to 6.00-inch rim-width range. The distinction comes more from appearance options: BFGoodrich appears in both narrow whitewall and wide whitewall form, while Coker Classic appears in wide whitewall form. That gives the buyer two different visual directions while staying inside the same fitment envelope.

For a restoration, that means the decision can hinge on what best matches the Buick’s personality and the way the car would have been presented in period. A narrow whitewall can suit a more restrained look, while a wider whitewall leans more formal and upscale. If your 1964 Buick is judged, select the version that best aligns with period photos and model-specific restoration practice rather than choosing only by brand name.

1964 Buick tire choices here are all bias-ply designs, and no speed ratings are shown for these sizes. In real-world use, a properly maintained bias-ply tire in the correct size can serve well for normal collector-car driving, but highway confidence depends on the whole car as much as the tire. Steering play, brake condition, suspension wear, alignment, and the general age of a 1964 Buick often become the limiting factors before a vintage-style bias-ply tire itself does.

That means a buyer should think in terms of the complete vehicle, not just the tread. A Riviera or Wildcat may feel capable at speed, but road manners still reflect 1964 chassis design and maintenance condition. If your Buick will see longer highway trips, inspect the tires carefully, keep pressures consistent, and make sure the car’s mechanical systems are sorted before treating any tire choice as the sole measure of roadworthiness.

Load-rated examples for 1964 Buick tires show several pressure pairings: 700-14 at 1360 pounds at 32 psi, 750-14 at 1500 to 1580 pounds at 32 psi, 710-15 at 1550 pounds at 32 psi, 760-15 at 1710 pounds at 32 psi, and 800-15 at 1800 pounds at 32 psi. Those figures describe the tire’s rated load relationship at that pressure, not a blanket instruction to inflate every Buick tire the same way. The correct service pressure should still be checked against the car’s factory guidance and the tire manufacturer’s recommendations.

That distinction matters because inflation needs can differ between a compact Special and a large Electra 225 even though both use period bias-ply construction. Do not transfer a pressure number from one size to another just because the tires look similar. Start with the exact size on the car, confirm the manufacturer’s guidance for that specific tire, and compare it with the original Buick literature before setting final pressure.

Before a longer drive in a 1964 Buick, inspect each tire for visible cracking, punctures, bulges, uneven wear, and any signs of age-related deterioration. Check cold pressure, confirm the tread is sound across the full contact area, and make sure the spare is still usable. Since every fitment here is bias-ply, it is also worth paying attention to how the car feels in the first few miles after storage, because flat-spotting can temporarily affect ride and steering feel.

Tires are only one part of the pre-trip check on a car of this age. A smart touring routine also includes brakes, wheel bearings, fluid levels, cooling system health, and steering response, especially on heavier Buick models that place more demand on older mechanical components. Giving the tires and the rest of the chassis equal attention is the best way to make a longer drive enjoyable rather than reactive.
