The 1984 Buick Regal sits at an interesting point in Buick history, bridging traditional personal-luxury styling with the sharper performance image that defined the G-body era. That matters when choosing tires, because this Regal family spans comfortable street trim, aluminum-wheel variations, and the increasingly sought-after Grand National and T-Type. Tire fitment is radial throughout, but the exact size changes by sub-model, with 14-inch and 15-inch applications both in the mix. Available choices range from whitewall-oriented classic radials to raised white letter, redline, dual-redline, OWL, and blackwall selections. The right pick depends on your Regal’s exact version, wheel diameter, and whether appearance or period driving character leads the decision.
Which Tire Size Is Right for The 1984 Buick Regal
The 1984 Buick Regal uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel setup. Two sizes fit 14-inch rims, while the performance-oriented 215/65R15 uses a 15-inch rim, so confirming both the Regal trim and actual wheel diameter should come first. Once that is settled, the decision shifts to sidewall style, tire series, and the kind of period presentation you want.
195/75R14 is a metric radial size in which 195 identifies nominal section width in millimeters, 75 is the aspect ratio, and 14 is the rim diameter in inches. On the 1984 Buick Regal, this size supports a more traditional 14-inch radial fitment used on Base models and Regal versions with aluminum wheels. Available choices lean toward classic street presentation, including wide whitewall and narrow whitewall options from Coker Classic, Tornel, Maxxis, and Travelstar. It is the right size to evaluate when your Regal retains the standard 14-inch wheel setup and a more formal period look matters as much as basic fitment.
Fit(s): Grand National, T-Type, and T-Type w/aluminum wheels
Construction: Radial|Rim: 15 in
215/65R15 is a metric radial size with a 215-millimeter nominal section width, a 65-series profile, and a 15-inch rim diameter. For the 1984 Buick Regal, this size belongs to Grand National and T-Type applications, where the 15-inch wheel is a central part of the fitment decision. Product choices span several visual directions, including OWL, raised white letter, redline, and wide whitewall tires from Goodyear, Cooper, and BFGoodrich. This is the size to focus on when your Regal carries the sportier 15-inch setup and you want to balance appearance, brand preference, and wheel compatibility.
205/70R14 is a metric radial size that combines a 205-millimeter nominal section width with a 70-series profile on a 14-inch rim. On the 1984 Buick Regal, it is used on Limited models, including Limited versions with aluminum wheels, making it distinct from both the Base 14-inch fitment and the 15-inch performance applications. Available tires include narrow whitewall, raised white letter, redline, dual-redline, and blackwall offerings from Maxxis, BFGoodrich, and Michelin. It is the key size to confirm when the car is a Limited and you want to match the vehicle’s character with the right sidewall treatment.
Sub-model fitment varies across the 1984 Buick Regal range, so tire selection starts with identifying the exact version of the car. That step matters because the Regal family uses both 14-inch and 15-inch rim diameters, and the sidewall and series choices that make sense can change with the original wheel setup.

1984 Buick Regal Base
The 1984 Buick Regal Base uses a 14-inch radial fitment centered on the 195/75R14 size. That keeps the buying decision focused on classic radial choices, especially whitewall presentation, while still making it important to confirm that the car has not been changed to a different wheel package.
The 1984 Buick Regal Grand National uses the 215/65R15 radial size on a 15-inch rim. That points the search toward the sportier side of the product range, where raised white letter, OWL, redline, and other appearance-driven options deserve a closer look.
The 1984 Buick Regal Limited uses the 205/70R14 radial size on a 14-inch rim. Tire selection here is less about choosing among multiple fitments and more about deciding which sidewall style best suits a luxury-oriented Regal with a restoration-friendly appearance in mind.
The 1984 Buick Regal Limited w/aluminum wheels also uses the 205/70R14 radial size. That means wheel material does not change the primary tire size, but the actual wheel on the car should still be checked before comparing whitewall, redline, dual-redline, or blackwall options.
The 1984 Buick Regal T-Type uses the 215/65R15 radial size on a 15-inch rim. That fitment opens the door to several performance-era visual styles, so the choice often comes down to whether the car is being kept closer to a street-performance look or a more understated presentation.
The 1984 Buick Regal T-Type w/aluminum wheels keeps the same 215/65R15 radial fitment as the standard T-Type. Tire choice therefore centers on sidewall style, brand, and rim-width compatibility rather than on a different primary size.
The 1984 Buick Regal w/aluminum wheels uses the same 195/75R14 radial size as the Base model. That keeps fitment straightforward, with the main decision shifting to which classic radial look best suits the car and whether the current wheel remains the original diameter.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Owners usually want to confirm the exact Regal sub-model first, then sort through wheel diameter, tire size, sidewall style, and period-appropriate radial choices. The questions below focus on the fitment details and buying decisions that matter most for a 1984 Buick Regal.
Tire Size & Fitment
What tire size fits a 1984 Buick Regal?
A 1984 Buick Regal uses one of three radial tire sizes: 195/75R14, 205/70R14, or 215/65R15. Base models and Regal versions with aluminum wheels use 195/75R14, Limited models use 205/70R14, and Grand National and T-Type models use 215/65R15.
The practical step is matching the tire to the exact sub-model and the actual wheel on the car. Since both 14-inch and 15-inch applications were used, it helps to confirm the wheel diameter before choosing a tire, especially on cars that may have been changed over the years.
What size rim does a 1984 Buick Regal use?
The 1984 Buick Regal uses either a 14-inch or 15-inch rim, depending on sub-model. The 195/75R14 and 205/70R14 fitments use 14-inch rims, while the 215/65R15 fitment used on Grand National and T-Type models uses a 15-inch rim.
Rim diameter is the first thing to verify because a 14-inch tire cannot be mounted on a 15-inch wheel, and the reverse is also true. After diameter is confirmed, compare the wheel width against the tire’s intended range and check that the car still has the wheel setup appropriate for its trim.
Do all 1984 Buick Regal sub-models use the same tire size?
No. The 1984 Buick Regal family uses three different radial tire sizes across its sub-models. Base and Regal with aluminum wheels use 195/75R14, Limited and Limited w/aluminum wheels use 205/70R14, and Grand National, T-Type, and T-Type w/aluminum wheels use 215/65R15.
That variation means tire selection should start with the exact sub-model rather than with the year and model alone. It is also smart to confirm the current wheel diameter, since older Regals are often modified, and a wheel swap can change which tire size makes sense for the car now.
Choosing the Right Tire
What should I consider when choosing a 1984 Buick Regal tire?
Start with the correct size for the exact sub-model, since the 1984 Buick Regal uses 195/75R14, 205/70R14, or 215/65R15 depending on trim. All are radial fitments, so the main choice is less about construction change and more about selecting the right sidewall style, brand, and tire series.
After confirming size and rim diameter, think about how the car is used and presented. A formal street Regal may look right with a whitewall, while a Grand National or T-Type often points buyers toward RWL, OWL, or redline options. Wheel width, load rating details, and the car’s current setup should also be checked before finalizing a choice.
What sidewall styles are available for 1984 Buick Regal tires?
Sidewall choices for the 1984 Buick Regal vary by size and include wide whitewall, narrow whitewall, OWL, RWL, redline, dual-redline, and blackwall. The available look depends on which primary size your Regal uses, so sidewall selection starts only after the fitment itself has been confirmed.
That variety makes appearance a major part of the buying decision. A Base or Limited Regal can take on a more formal period-style look with whitewalls, while Grand National and T-Type applications often line up with sportier lettering or stripe treatments. The best approach is to match the sidewall style to the car’s trim, wheel design, and overall restoration direction.
What brands offer tires for the 1984 Buick Regal?
Depending on size, 1984 Buick Regal tires are available from Coker Classic, Tornel, Maxxis, Travelstar, Goodyear, Cooper, BFGoodrich, and Michelin. Brand availability changes with the tire size, so the broadest comparison happens only after narrowing the search to the correct fitment for the specific Regal sub-model.
Once the size is settled, brand comparison becomes a matter of series character, sidewall treatment, and wheel compatibility rather than simple name recognition. Some options lean traditional with whitewalls, while others reflect the 1980s performance look with raised white letters or stripe treatments. Checking the details within the correct size is more useful than comparing brands in the abstract.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Buick Regal?
A period-style 1984 Buick Regal tire starts with the correct original fitment family for the sub-model: 195/75R14, 205/70R14, or 215/65R15. From there, the right choice depends on the character you want the car to present, whether that means a traditional whitewall appearance or a more performance-oriented sidewall treatment.
A Base or Limited Regal often suits whitewall styles, while Grand National and T-Type models usually invite a sportier visual approach such as RWL, OWL, or redline. For a restoration where exact historical appearance matters, compare the tire choice against period photos, build records, and marque-specific references rather than relying on size alone.
How does tire construction affect the appearance of a restored 1984 Buick Regal?
On a 1984 Buick Regal, construction is straightforward because the primary fitments are radial. The visual difference comes less from bias-ply versus radial concerns and more from the sidewall itself, including whitewall width, raised white letters, OWL, redline, dual-redline, or blackwall presentation within the correct radial size.
That means a restored Regal can change character noticeably even when the tire size stays correct. A whitewall can support a more formal luxury look, while lettering or colored stripes can push the car toward an unmistakably 1980s performance feel. Choosing the sidewall with the trim and wheel style in mind usually has the biggest effect on overall appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Buick Regal?
Yes. Wheel swaps, suspension changes, lowering, altered springs, or body modifications can affect tire fitment on a 1984 Buick Regal even when the chosen size matches a known factory application. This matters especially because the Regal range used both 14-inch and 15-inch wheel diameters depending on sub-model.
A modified car should be checked for wheel diameter, wheel width, and available clearance before any tire is selected. Steering travel, fender space, and the position of the tire in the wheel opening all matter. On an older Regal, confirming the car’s current setup is often just as important as knowing its original trim designation.
What should I inspect before driving a 1984 Buick Regal on new tires?
Before driving a 1984 Buick Regal on new tires, inspect the wheels for the correct diameter and condition, then confirm inflation pressure, valve condition, and proper mounting. It also helps to look over suspension and steering components so the new tires are not asked to compensate for worn parts.
After installation, check for clearance at full steering lock and over suspension movement, especially if the car has aftermarket wheels or a changed ride height. During the first drives, pay attention to air retention, unusual vibration, and any sign of rubbing. A collector-era Regal benefits from a careful recheck after the tires have seen some road use.
How should tires on a collector 1984 Buick Regal be maintained?
Tires on a collector 1984 Buick Regal should be maintained with regular pressure checks, visual inspections, and attention to age and condition as well as tread depth. Even a low-mile car can develop sidewall cracking, flat spotting, or air-loss issues when it spends long periods parked.
Storage conditions matter almost as much as road use. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and moving the vehicle periodically can reduce stress from long stationary periods. Before any longer drive, inspect for cuts, bulges, and uneven wear, and verify that the tires still suit the car’s current wheel setup.
