The 1984 Oldsmobile Firenza sits squarely in the front-wheel-drive compact era, when domestic small cars were balancing fuel economy, everyday practicality, and a more tailored trim strategy than many economy models of the period. For owners today, tire choice depends less on broad model history and more on confirming the exact Firenza sub-model and wheel setup. Most 1984 Firenza variants use 13-inch radial sizes, either 175/80R13 or 195/70R13, while the Firenza GT moves to a 205/60R14 radial on a 14-inch rim. That creates meaningful differences in sidewall appearance, wheel diameter, and product choice, especially for buyers aiming to preserve an unmistakably mid-1980s road-car look.
Which Tire Size Is Right for The 1984 Oldsmobile Firenza
Three primary tire sizes apply to the 1984 Oldsmobile Firenza, and the right one depends first on the exact sub-model and wheel diameter. Most Firenza variants use one of two 13-inch radial sizes, while the GT uses a 14-inch radial. Before choosing a tire, confirm whether the car is a GT or another Firenza trim and verify the actual wheel diameter on the vehicle, especially if wheels have been changed over the years.
205/60R14 is a metric radial size that uses a 205-millimeter nominal section width, a 60-series profile, and a 14-inch rim. On the 1984 Oldsmobile Firenza, this size is tied to the GT and stands apart from the 13-inch fitments used elsewhere in the model range. Its shorter sidewall and larger wheel diameter make wheel confirmation especially important before any purchase. Buyers looking at this size should focus on the GT-specific setup first, then compare tire dimensions, wheel width, and available product characteristics to avoid mixing 13-inch and 14-inch applications.
Sub-model fitment matters on the 1984 Oldsmobile Firenza because most trims share 13-inch radial choices, while the GT uses a separate 14-inch size. Identifying the exact Firenza sub-model is the quickest way to narrow the correct tire size before comparing sidewall style or product details.

1984 Oldsmobile Firenza Base
The 1984 Oldsmobile Firenza Base uses one of two 13-inch radial sizes, either 175/80R13 or 195/70R13. That means the key step is confirming which 13-inch fitment is on the car now, then choosing between the available sidewall presentations and product specifications within that size.
The 1984 Oldsmobile Firenza Brougham LX also falls within the 13-inch radial fitment group, using either 175/80R13 or 195/70R13. Tire selection starts with confirming the actual wheel and size on the vehicle, then comparing the available whitewall style and tire-series options that suit the car's intended presentation.
The 1984 Oldsmobile Firenza Brougham SX shares the same two 13-inch radial size choices used on many Firenza variants: 175/80R13 and 195/70R13. Owners should verify which size is mounted before selecting a replacement, since the choice affects profile, appearance, and the product options available in the correct size.
The 1984 Oldsmobile Firenza Cruiser uses either 175/80R13 or 195/70R13 on a 13-inch radial setup. That makes wheel and existing tire confirmation more important than broad model identification, especially when deciding between a taller-profile fitment and a lower-profile 13-inch alternative.
The 1984 Oldsmobile Firenza Cruiser LX remains in the same 13-inch radial fitment group as other non-GT Firenza models, using 175/80R13 or 195/70R13. Once the exact size on the car is confirmed, the next decision becomes sidewall style and tire-series choice rather than construction type, since these are radial applications.
The 1984 Oldsmobile Firenza Cruiser SX uses one of the two standard 13-inch radial sizes found across much of the Firenza lineup: 175/80R13 or 195/70R13. Buyers should confirm the current wheel and tire setup first, then compare available product details within the correct size rather than assuming all 13-inch Firenzas use the same profile.
The 1984 Oldsmobile Firenza ES uses either 175/80R13 or 195/70R13, both in radial construction on 13-inch rims. Tire selection here is mainly about verifying which of those two profiles belongs on the car and then choosing the sidewall treatment and series that best suit the intended look.
The 1984 Oldsmobile Firenza GT stands apart from the rest of the range by using 205/60R14 radial tires. That makes wheel diameter confirmation especially important, since GT fitment is not interchangeable with the Firenza's 13-inch primary sizes without checking the entire wheel and clearance setup.
The 1984 Oldsmobile Firenza LX uses the same pair of 13-inch radial fitments seen on many other trims: 175/80R13 and 195/70R13. The practical choice is to verify which size is actually on the vehicle, then compare the available tire style, series, and rim-width compatibility within that confirmed size.
The 1984 Oldsmobile Firenza S shares the two standard 13-inch radial tire sizes used across most non-GT Firenza models, 175/80R13 and 195/70R13. That makes exact size verification essential before replacement, since both fitments use the same rim diameter but present different tire proportions and product choices.
The 1984 Oldsmobile Firenza SX uses one of two 13-inch radial sizes, 175/80R13 or 195/70R13. Once the actual size on the car has been confirmed, tire selection becomes a matter of choosing the right sidewall appearance and product details for the way the car is being maintained or presented.
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.

These 1984 Oldsmobile Firenza tire FAQs focus on the three primary sizes, the difference between 13-inch and 14-inch fitment, available whitewall styles, and the practical checks that matter before putting a Firenza back on the road.
Tire Size & Fitment
What tire size fits a 1984 Oldsmobile Firenza?
The 1984 Oldsmobile Firenza uses three primary radial tire sizes across the model range: 175/80R13, 195/70R13, and 205/60R14. Most Firenza sub-models use one of the two 13-inch sizes, while the Firenza GT uses 205/60R14 on a 14-inch rim.
The practical question is not just the model year, but the exact sub-model and wheel on the car. Many non-GT Firenzas can fall into either 13-inch size group, so checking the existing tire size and actual wheel diameter is the safest way to narrow the correct replacement before comparing sidewall style or brand.
What size rim does a 1984 Oldsmobile Firenza use?
A 1984 Oldsmobile Firenza uses either a 13-inch or 14-inch rim, depending on sub-model and tire size. The 175/80R13 and 195/70R13 fitments use 13-inch rims, while the 205/60R14 fitment uses a 14-inch rim on the Firenza GT.
Rim diameter should be confirmed before anything else, because a 13-inch tire cannot be mounted on a 14-inch wheel, and the reverse is equally true. If the car has had wheel changes during its life, inspect the actual wheel and current tire markings rather than relying only on model identification.
Why does the 1984 Oldsmobile Firenza have more than one tire size?
The 1984 Oldsmobile Firenza has more than one tire size because fitment varies across the sub-model range. Most versions use either 175/80R13 or 195/70R13, while the GT uses a separate 205/60R14 size tied to a different wheel diameter and overall setup.
That means tire selection starts with identifying the exact Firenza trim and confirming the wheel currently on the car. Even among the 13-inch applications, two different profiles are used, so it helps to check what is mounted now and match the replacement to the intended fitment rather than assuming all Firenzas are the same.
Choosing the Right Tire
What should I consider when choosing a 175/80R13 or 195/70R13 tire for a 1984 Oldsmobile Firenza?
Start with the exact size already established for the car, since both 175/80R13 and 195/70R13 are used on 13-inch Firenza applications but are not the same fitment. Then compare radial construction details, rim-width compatibility, sidewall style, tire series, and load capacity within that confirmed size.
A 175/80R13 selection may appeal to owners looking for a taller-profile 13-inch presentation, while 195/70R13 keeps the choice in a lower-profile 13-inch format. Once the correct size is settled, the decision becomes more about appearance and product specifications than broad vehicle compatibility.
What sidewall styles are available for 1984 Oldsmobile Firenza tires?
Available sidewall styles for 1984 Oldsmobile Firenza tires include narrow whitewall and wide whitewall treatments in the 13-inch fitments. The 175/80R13 options include both narrow and wide whitewall choices, while the available 195/70R13 product uses a narrow whitewall sidewall style.
Sidewall treatment can make a noticeable difference on a mid-1980s compact, especially if the goal is to preserve a more traditional showroom-era appearance. After confirming the correct size, compare sidewall style with the overall look of the car, since the right visual balance may matter as much as the brand name.
What brands offer tires for the 1984 Oldsmobile Firenza?
Tires for the 1984 Oldsmobile Firenza are available from Maxxis and BFGoodrich in the supported 13-inch radial sizes. The 175/80R13 fitment includes both brands, while the available 195/70R13 product is offered in the BFGoodrich Silvertown Radial line.
Brand matters most after the size has been confirmed, because each available option also brings differences in sidewall presentation and tire series. Rather than treating brand alone as the deciding factor, compare the full package of size, rim-width suitability, whitewall style, and overall look for the specific Firenza.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Oldsmobile Firenza?
For a period-style 1984 Oldsmobile Firenza, the first step is staying with the correct primary size for the exact sub-model and wheel diameter. Once that is settled, the 13-inch radial choices with whitewall treatments offer a presentation that suits the car's mid-1980s character better than a generic modern-looking replacement.
Appearance goals usually come down to profile and sidewall treatment. A taller 175/80R13 and a lower 195/70R13 create different visual impressions even though both are 13-inch fitments, so owners concerned with restoration-style presentation should confirm the intended size before choosing between narrow or wide whitewall options.
How does tire construction affect the appearance of a restored 1984 Oldsmobile Firenza?
On a 1984 Oldsmobile Firenza, the primary fitments are radial tires, so construction changes are less about bias-ply versus radial and more about selecting the right radial size and sidewall look. The profile of the tire and the whitewall treatment have the strongest effect on how restored or era-appropriate the car appears.
A correctly sized radial with a suitable whitewall can preserve the visual character of the car far better than an incorrect modern substitute with a mismatched profile. Owners pursuing exact originality should still compare their car against marque-specific references, since appearance details can vary by trim, market, and prior wheel changes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Oldsmobile Firenza?
Yes, modifications can affect tire fitment on a 1984 Oldsmobile Firenza. Aftermarket wheels, altered wheel width, suspension changes, or body modifications can all change how a 13-inch or 14-inch tire fits, even when the tire size itself is one of the standard Firenza fitments.
That matters especially on a car with multiple original sizes and two different rim diameters in the model range. A Firenza GT setup should not be assumed on a non-GT car, and any changed wheel or suspension combination should be checked for diameter, width, steering travel, and fender clearance before replacement tires are chosen.
What should I inspect before driving a 1984 Oldsmobile Firenza on new tires?
Before driving a 1984 Oldsmobile Firenza on new tires, inspect the wheels for the correct diameter and condition, verify the tire pressure, and make sure there is no interference at the fenders or during full steering travel. It also helps to confirm that the tires match side to side on the same axle.
On a collector or low-use car, tire condition is only part of the picture. Check suspension wear, alignment-related irregular tread wear, air retention, and the overall state of the wheels before putting road miles on the car, especially if the Firenza has been sitting or has recently changed hands.
How should tires on a collector 1984 Oldsmobile Firenza be maintained?
Tires on a collector 1984 Oldsmobile Firenza should be checked regularly for pressure, cracking, bulges, cuts, uneven wear, and signs of air loss, even if the car is driven only occasionally. Low-use collector cars can age tires slowly in miles but quickly in time, storage conditions, and exposure.
Good storage habits help preserve both appearance and service life. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources, then inspecting the tires before each drive, is especially important on an older Firenza that may spend long periods parked between outings.
