The 1964 Buick Electra 225 sits firmly in the full-size luxury tradition of the mid-1960s, when long wheelbases, substantial curb presence, and a smooth highway ride defined premium American motoring. Owners restoring or maintaining one of these big Buicks usually want a tire that supports both the car’s visual character and its road manners. The primary fitment is an 800-15 bias-ply tire on a 15-inch rim, which keeps the period-style sizing and stance intact. Available choices center on Coker Classic Bias Ply options with wide whitewall treatments, while radial equivalents are also available for buyers considering a different construction. The key is deciding whether appearance, driving feel, or a balance of both matters most for this exact Electra 225.
Which Tire Size Is Right for The 1964 Buick Electra 225
The 1964 Buick Electra 225 uses one primary tire size: 800-15. That size is a bias-ply fitment on a 15-inch rim, and the same size applies to the covered Base sub-model. With fitment settled, the real choice becomes selecting the right wide whitewall presentation in the proper size or deciding whether to stay with bias-ply construction or evaluate one of the available radial equivalents.
An 800-15 numeric bias-ply size uses the leading number to indicate a nominal section width of about 8.00 inches, while the final number identifies a 15-inch wheel. On the 1964 Buick Electra 225, this is the primary bias-ply fitment and it suits the large-car, mid-1960s tire profile many restoration-minded owners want to preserve. Available options in this size come from the Coker Classic Bias Ply line and focus on wide whitewall styling, including 3.00-inch and 2.50-inch whitewall treatments. This size is the right starting point when maintaining original-style proportions and confirming wheel width before choosing a specific tire.
Tire fitment is straightforward for the covered 1964 Buick Electra 225 sub-model. The Base model uses the same primary size, so the focus shifts from identifying fitment to choosing the right appearance and construction approach for the car’s intended use.

1964 Buick Electra 225 Base
The 1964 Buick Electra 225 Base uses the 800-15 bias-ply tire size on a 15-inch rim. That makes selection more about choosing the preferred wide whitewall presentation or considering a radial equivalent while still checking wheel width and overall clearance before changing construction.
Bias-Ply to Radial Tire Conversion for the 1964 Buick Electra 225
The original 800-15 tire size has four radial-equivalent options to consider for the 1964 Buick Electra 225. Those include 225R15 as an 80-series metric radial, P235/75R15 as a P-metric 75-series radial, P235/70R15 as a P-metric 70-series radial, and 800R15 as a bias-look radial equivalent. Together, these options span traditional metric sizing, lower-profile P-metric alternatives, and a radial that keeps a more vintage presentation. A 6-8 inch rim width range is associated with these equivalents, and wheel compatibility, overall dimensions, and vehicle clearance should all be checked before making a change.

Best 1964 Buick Electra 225 Tires for Sale
Available 800-15 choices for the 1964 Buick Electra 225 center on Coker Classic Bias Ply tires with wide whitewall styling. The main comparison point in the product grid is whitewall width, with both 3.00-inch and 2.50-inch whitewall options in the same period-style size and construction.
These FAQs focus on 1964 Buick Electra 225 tire size, 15-inch rim fitment, 800-15 bias-ply selection, radial-equivalent choices, wide whitewall appearance, and the checks that matter before road use on a large collector Buick.
Tire Size & Fitment
What tire size fits a 1964 Buick Electra 225?
The 1964 Buick Electra 225 uses an 800-15 tire size. This is a numeric bias-ply size mounted on a 15-inch rim, and it is the primary fitment for the covered Electra 225 application.
That means the first step is matching the 800-15 size before comparing whitewall treatment or considering a radial equivalent. On a collector car like the Electra 225, it is also smart to confirm the actual wheel setup on the car, since replacement wheels or past modifications can change what should be ordered.
What size rim does a 1964 Buick Electra 225 use?
The primary tire fitment for the 1964 Buick Electra 225 is built around a 15-inch rim. The 800-15 size uses that 15-inch wheel diameter, which is the key wheel measurement tied to the original-style fitment.
Rim diameter should be confirmed before any tire purchase, especially on an older full-size car that may have seen wheel changes over the years. If a radial equivalent is being considered, wheel width matters too, since an equivalent can share the same diameter while still needing the right width and clearance to work properly.
Does the 1964 Buick Electra 225 Base use the same tire size?
Yes. The 1964 Buick Electra 225 Base uses the same 800-15 bias-ply tire size as the core Electra 225 fitment. That keeps sub-model fitment simple for the covered application.
With the size already established, the buyer decision is less about identifying fitment and more about selecting the right style and construction. For most owners, that means choosing between available wide whitewall looks in 800-15 or reviewing the radial-equivalent options while confirming the wheels actually on the car.
Bias-Ply & Radial Options
Is 800-15 a bias-ply or radial tire for the 1964 Buick Electra 225?
For the 1964 Buick Electra 225, 800-15 is the primary bias-ply tire size. In this vehicle’s original-style sizing format, the numeric code belongs to a vintage bias-ply fitment on a 15-inch rim.
That matters because staying with bias-ply preserves the period-style size convention and appearance many restorations aim for. A radial can still be considered through an equivalent size, but changing construction should prompt a closer look at wheel width, tire dimensions, and clearance rather than assuming every 15-inch option behaves the same way.
What radial tire sizes are equivalent to 800-15?
Radial equivalents for 800-15 include 225R15, P235/75R15, P235/70R15, and 800R15. Those options cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial that keeps a more vintage visual character.
Each of those sizes gives a different way to approach radial construction while staying in the same general fitment conversation. The associated rim width range is 6-8 inches, but diameter, section width, wheel compatibility, and body or steering clearance should still be checked on the actual Electra 225 before selecting an equivalent.
Can I use a bias-look radial on a 1964 Buick Electra 225?
Yes, an 800R15 bias-look radial is available as a radial equivalent for the 1964 Buick Electra 225’s original 800-15 size. It gives buyers a way to consider radial construction while retaining a more traditional tire presentation than a modern P-metric size might show.
That option can make sense when appearance matters but the owner still wants to evaluate a radial-format alternative. It should still be treated as an equivalent, not an automatic substitute, so wheel width, overall dimensions, and fender or steering clearance deserve the same careful review as any other conversion from bias-ply.
Choosing the Right Tire
What should I consider when choosing a 800-15 tire for a 1964 Buick Electra 225?
Start with the correct primary size, which is 800-15 for the 1964 Buick Electra 225. From there, the main selection factors are maintaining bias-ply construction, choosing the preferred wide whitewall presentation, and confirming the tire suits the wheel width being used.
Available 800-15 choices here stay within the same Coker Classic Bias Ply series, so the visual difference is mainly the whitewall width rather than a change in basic construction. It also helps to think about how the car will be used, since a restoration-focused car may call for a different choice than one being evaluated for radial-equivalent alternatives.
What sidewall styles are available for 1964 Buick Electra 225 tires?
The available 800-15 options for the 1964 Buick Electra 225 use a wide whitewall sidewall style. Within that style, the visible choice is the whitewall width, with both 3.00-inch and 2.50-inch whitewall treatments offered in the same size.
That makes sidewall appearance one of the biggest visual decisions on this page, especially on a full-size Buick where whitewall proportion has a strong effect on the car’s stance and presentation. Buyers comparing the two should think about the look they want on the finished car rather than assuming one width is universally right.
What tire series are available for the 1964 Buick Electra 225?
The available primary-size products for the 1964 Buick Electra 225 are in the Coker Classic Bias Ply series. Both 800-15 options share that same series and construction, so the comparison stays focused on appearance within a consistent period-style bias-ply format.
Since the series remains the same, the practical selection differences are narrower than on pages with multiple brands or multiple tread families. Wheel compatibility, intended visual presentation, and whether the car will remain on bias-ply or move to a radial equivalent are more useful deciding factors than series comparison alone.
Restoration & Appearance
Which tire should I choose for a period-style 1964 Buick Electra 225?
For a period-style 1964 Buick Electra 225, the natural starting point is the 800-15 bias-ply size. That keeps the car in its vintage numeric sizing format and supports the tall, substantial full-size Buick look associated with mid-1960s luxury cars.
Within that size, the appearance decision centers on the available wide whitewall treatments rather than changing to a different primary fitment. If exact historical originality is the goal, marque references and restoration documentation are worth consulting, since period-style and exact factory delivery are not always the same thing.
How does tire construction affect the appearance of a restored 1964 Buick Electra 225?
Tire construction affects more than ride and road feel on a restored 1964 Buick Electra 225; it also changes how the car presents visually. The original-style 800-15 bias-ply format keeps the vintage sizing language and traditional look that many restoration-minded owners expect on a large Buick of this era.
A radial equivalent can still be a reasonable option, but modern metric or P-metric markings create a different visual impression than a numeric bias-ply sidewall. An 800R15 bias-look radial offers another path for owners who want a more traditional appearance while still considering radial construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1964 Buick Electra 225?
Yes. A 1964 Buick Electra 225 may have the correct primary tire size on paper and still need a closer fitment check if the car has aftermarket wheels, suspension changes, altered ride height, or body work that changes available clearance.
That is especially important when considering a radial equivalent instead of the original-style 800-15 bias-ply size. Wheel diameter, wheel width, steering travel, and fender clearance should all be reviewed on the actual car, because a modified Electra 225 can differ significantly from one retaining its stock wheel and suspension layout.
What should I inspect before driving a 1964 Buick Electra 225 on new tires?
Before driving a 1964 Buick Electra 225 on new tires, inspect the wheels for correct diameter and condition, confirm proper inflation, and make sure the tires seat correctly and clear the car through steering movement. Lug hardware, valve stems, and overall wheel condition deserve attention as well.
On a collector Buick, it also helps to look beyond the tires themselves. Suspension wear, brake condition, alignment, and any long-term storage effects can influence how the car feels on the road. A short local drive followed by another visual inspection is a smart way to catch rubbing, air loss, or mounting issues early.
How should 800-15 tires on a collector 1964 Buick Electra 225 be maintained?
800-15 tires on a collector 1964 Buick Electra 225 should be checked regularly for inflation, visible cracking, bulges, cuts, uneven wear, and signs of air loss. On a car that is not driven often, condition matters just as much as tread depth because age and storage can affect the tire long before the tread is worn out.
Good maintenance also means protecting the car from prolonged sunlight, excess heat, moisture, and ozone sources during storage. Occasional movement helps reduce flat-spotting on bias-ply tires, and any change in ride quality, steering feel, or visible sidewall condition should prompt a closer inspection before the next longer drive.
