The 1984 Mazda GLC came from an era when compact imports were prized for efficiency, light weight, and straightforward road manners rather than excess. That makes tire choice especially important, because a small car like the GLC responds noticeably to changes in size, profile, and construction. This model uses 13-inch radial fitments, with 155R13 and 6.15R13 covering Base, DX, and LX versions, while the Sport 3 Dr. uses 175/70R13. Available choices lean toward blackwall radial designs from Michelin, Dunlop, and Avon. The real decision is matching the correct sub-model and preserving the right balance of appearance, wheel compatibility, and intended driving use.
Which Tire Size Is Right for The 1984 Mazda GLC
Three primary tire sizes apply to the 1984 Mazda GLC, and the right one depends first on identifying the exact sub-model. Base, DX, and LX versions use 155R13 or 6.15R13 on 13-inch rims, while the Sport 3 Dr. uses 175/70R13 on a 13-inch rim. Once that is confirmed, the choice shifts to sizing format, tire character, and the available radial product options within the correct fitment.
155R13 is a Euro-metric radial size with a 155 millimeter nominal section width, radial construction, and a 13-inch rim diameter. On the 1984 Mazda GLC, this size is used on Base, DX, and LX models and keeps the car in a traditional compact-import radial format. Available choices include blackwall tires from Michelin and Dunlop, with series such as Michelin XAS-FF and SP Sport Aquajet. It is a useful size for owners who want a conventional radial fitment and should be matched to the actual wheel and sub-model before selection.
6.15R13 uses a vintage-style radial size designation built around an approximate section width and a 13-inch rim diameter rather than a modern metric profile expression. On the 1984 Mazda GLC, it applies to Base, DX, and LX versions and offers a more traditional-looking sizing format while remaining a radial construction. Its value is largely in presentation, especially for owners trying to preserve an earlier import-tire look on a compact 1980s Mazda. Wheel dimensions and the actual tire installed on the car should be confirmed before moving from one radial sizing convention to another.
175/70R13 is a modern metric radial size that states both section width and aspect ratio, followed by radial construction and a 13-inch rim diameter. For the 1984 Mazda GLC, this size belongs to the Sport 3 Dr. and reflects a lower-profile metric format than the 155R13 fitments used on other sub-models. Avon offers this size in a blackwall CR6ZZ series, giving buyers a defined product choice within the correct Sport 3 Dr. sizing. It should be selected only after confirming that the car is the Sport 3 Dr. and still uses the proper 13-inch wheel setup.
Sub-model fitment matters on the 1984 Mazda GLC because not every version uses the same tire size. Base, DX, and LX models share the same 13-inch radial fitment path, while the Sport 3 Dr. moves to a different metric radial size, so confirming the exact trim is the first step.

1984 Mazda GLC Base
The 1984 Mazda GLC Base uses the same radial fitment pattern as the DX and LX, centered around 155R13 and 6.15R13. That gives the buyer a choice between a more conventional Euro-metric radial presentation and a vintage-style radial sizing format on the same 13-inch wheel diameter.
The 1984 Mazda GLC DX shares its tire-fitment situation with the Base and LX, using 155R13 or 6.15R13 radial sizes on 13-inch rims. Tire selection here is less about sub-model differences and more about choosing the right radial style, appearance, and wheel-compatible option.
The 1984 Mazda GLC LX follows the same tire-size pattern as the Base and DX, using 155R13 or 6.15R13 radial fitments. That makes selection relatively straightforward, but it still helps to confirm the wheels on the car before choosing between modern-looking and vintage-style radial formats.
The 1984 Mazda GLC Sport 3 Dr. uses 175/70R13 rather than the 155R13 and 6.15R13 sizes seen on other GLC sub-models. That makes trim identification important, since tire choice here centers on the correct lower-profile metric radial format and compatibility with the existing 13-inch wheels.
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.
Best 1984 Mazda GLC Tires for Sale
Available 1984 Mazda GLC tire choices center on blackwall radial designs in the correct 13-inch sizes. Buyers can compare Michelin and Dunlop options in 155R13, along with an Avon CR6ZZ choice in 175/70R13, with differences in tire series, rim-width range, and overall presentation.
These 1984 Mazda GLC tire FAQs focus on the exact fitment questions that matter most: which size belongs on each sub-model, how the 13-inch radial sizes differ, what to compare among available products, and what to inspect before road use.
Tire Size & Fitment
What tire size fits a 1984 Mazda GLC?
The 1984 Mazda GLC uses three primary radial tire sizes, but not every sub-model uses all three. Base, DX, and LX versions use 155R13 or 6.15R13, while the Sport 3 Dr. uses 175/70R13. All of these fitments are built around a 13-inch rim diameter.
The key is confirming the exact sub-model before choosing a tire. A Base, DX, or LX owner will usually be deciding between two radial sizing formats, while a Sport 3 Dr. owner needs the specific 175/70R13 fitment. It is also wise to confirm the actual wheel size on the car, especially if wheels have been changed over the years.
What size rim does a 1984 Mazda GLC use?
The 1984 Mazda GLC uses a 13-inch rim diameter across its primary tire fitments. That applies to 155R13, 6.15R13, and 175/70R13, so the rim diameter stays consistent even though the tire sizing format changes by sub-model.
Rim diameter is only part of the picture, so wheel width still matters when comparing actual tires. Some available products also include rim-width guidance, such as 4.00 to 5.50 inches for certain 155R13 options and 4.5 to 6.0 inches for a 175/70R13 option. Verifying both diameter and width helps prevent selection mistakes.
Do all 1984 Mazda GLC sub-models use the same tire size?
No, the 1984 Mazda GLC does not use one tire size across every sub-model. Base, DX, and LX models share 155R13 and 6.15R13 radial fitments, while the Sport 3 Dr. uses 175/70R13. That means trim level directly affects tire selection on this vehicle.
This difference matters because 175/70R13 is a modern metric profile size, while 155R13 and 6.15R13 follow different radial sizing conventions. A buyer should identify the exact GLC sub-model first, then confirm the wheel setup currently on the car. That approach avoids mixing fitments intended for different versions of the same model line.
Choosing the Right Tire
What should I consider when choosing a 155R13 tire for a 1984 Mazda GLC?
A 155R13 tire for a 1984 Mazda GLC should first match the correct sub-model group, which includes Base, DX, and LX. After that, the main factors are radial construction, 13-inch wheel compatibility, and the product character offered by the available tires, including Michelin XAS-FF and Dunlop SP Sport Aquajet blackwall options.
The practical choice depends on how the car is used and how closely the owner wants to stay with a traditional compact-import presentation. Rim width is worth checking carefully, since some 155R13 products include specific wheel-width guidance. Comparing the installed wheel, intended driving use, and the look you want usually narrows the right choice quickly.
What sidewall styles are available for 1984 Mazda GLC tires?
The available 1984 Mazda GLC tire options shown here use blackwall sidewalls. That applies to the 155R13 choices from Michelin and Dunlop as well as the 175/70R13 Avon option, so the overall look stays clean and understated rather than emphasizing whitewall or raised-letter styling.
For many compact 1980s imports, blackwall tires suit the car's original character without drawing attention away from the wheel and body lines. Sidewall style should still be considered alongside the correct size and sub-model, since appearance alone does not determine fitment. Choosing the proper tire size first keeps the presentation aligned with the car's proportions.
What brands offer tires for the 1984 Mazda GLC?
Michelin, Dunlop, and Avon offer tires in the primary sizes used on the 1984 Mazda GLC. Michelin and Dunlop appear in the 155R13 fitment, while Avon covers the 175/70R13 size used on the Sport 3 Dr. All of the available choices are radial tires built for 13-inch rims.
Brand should be considered alongside size, sub-model, and the tire series itself rather than treated as the only deciding factor. A Base, DX, or LX owner will be comparing Michelin and Dunlop within 155R13, while a Sport 3 Dr. owner will focus on the available 175/70R13 option. Matching the right tire to the right trim comes first.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Mazda GLC?
A period-style 1984 Mazda GLC tire choice starts with the correct sub-model and size. Base, DX, and LX models center on 155R13 or 6.15R13 radial fitments, while the Sport 3 Dr. uses 175/70R13. Among those, 6.15R13 brings a more vintage-looking sizing convention, while 155R13 keeps a traditional Euro-metric radial format.
Appearance should be balanced with the car's actual wheel setup and intended use. Blackwall sidewalls keep the presentation restrained, which suits many small Japanese cars of the era. When exact originality matters, it helps to compare the car against marque references, surviving examples, or period documentation before settling on one size format or tire series.
Does correct tire fitment matter for a 1984 Mazda GLC restoration?
Yes, correct tire fitment matters on a 1984 Mazda GLC restoration because size, profile, and sizing format all influence how the car sits and reads visually. A Base, DX, or LX on 155R13 or 6.15R13 presents differently from a Sport 3 Dr. on 175/70R13, even though all of them use 13-inch rims.
Restoration-minded owners usually want the tire to support the car's era and trim rather than look generically modern. That makes sub-model identification especially important on the GLC. The right choice is not just about mounting a tire that fits the wheel, but about preserving the proportions and character appropriate to the version being restored.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Mazda GLC?
Yes, modifications can affect tire fitment on a 1984 Mazda GLC even when the original tire sizes are known. Changes such as aftermarket wheels, altered wheel width, different offset, suspension lowering, or body modifications can change how a 155R13, 6.15R13, or 175/70R13 tire sits in the wheel opening.
That matters most on a light compact car, where small dimensional changes can quickly influence steering and clearance. A modified GLC should have its actual wheel diameter, wheel width, and available clearance checked before selecting tires. Even with the correct nominal size, the current setup may no longer match the way the car was originally configured.
What should I inspect before driving a 1984 Mazda GLC on new tires?
Before driving a 1984 Mazda GLC on new tires, inspect the wheels for correct diameter and condition, confirm proper inflation, and check that the tires clear the suspension, steering components, and fenders. Lug hardware, valve stems, and the overall condition of the wheel mounting surfaces also deserve attention.
A short initial drive followed by a second inspection is a smart step on any older car. Watch for rubbing, uneven stance, vibration, or signs of air loss once the tires have seated and the vehicle has been driven. On a GLC that has sat for long periods, suspension wear and alignment condition should also be considered.
How should tires on a collector 1984 Mazda GLC be maintained?
Tires on a collector 1984 Mazda GLC should be maintained with regular pressure checks, visual inspections, and attention to age-related condition as well as tread wear. Older collector cars often see limited mileage, so sidewall cracking, flat spotting, cuts, bulges, and slow air loss may matter more than simple tread depth.
Storage conditions also play a large role in tire life. Keeping the car away from prolonged sunlight, moisture, excessive heat, and ozone sources can help preserve the tires between drives. It also helps to inspect the tires before every outing, since a low-use GLC may develop age or storage issues long before the tread appears worn out.
