The 1979 Oldsmobile Cutlass landed in an era when midsize American cars balanced comfort, everyday drivability, and personal-luxury styling, and the Cutlass name had become a familiar sight in driveways across the country. Buyers restoring or maintaining one today usually care just as much about stance and sidewall appearance as they do about road manners. This exact 1979 Oldsmobile Cutlass uses 14-inch radial tire fitments, with 185/75R14, 195/75R14, and 205/70R14 all appearing across different sub-models. That opens up meaningful choices in whitewall, redline, raised white letter, and blackwall designs. The key is matching the right size to the right Cutlass configuration before narrowing the look and tire series that suits the car.
Which Tire Size Is Right for The 1979 Oldsmobile Cutlass
Three primary tire sizes apply to the 1979 Oldsmobile Cutlass, and all of them are radial fitments for 14-inch wheels. The right choice depends first on the exact sub-model, since different Cutlass versions use different sizes even though the rim diameter stays the same. Once the correct size is confirmed, the decision shifts to sidewall style, brand, tire series, and the kind of appearance you want the car to carry.
195/75R14 is a metric radial size in which 195 refers to nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 14 is the wheel diameter in inches. On the 1979 Oldsmobile Cutlass, this size is one of the central fitments and appears across several sub-model applications. Product choices include Coker Classic, Tornel, Maxxis, and Travelstar, with both wide whitewall and narrow whitewall presentations available across several tire series. It is a useful size to evaluate when maintaining a traditional late-1970s look while still having several brand and sidewall options to compare.
205/70R14 is a metric radial size with a 205-millimeter nominal width, a 70-series profile, radial construction, and a 14-inch rim diameter. For the 1979 Oldsmobile Cutlass, this size is tied to specific sub-model applications rather than every configuration. Available tires span a broader range of visual character, including narrow whitewall, raised white letter, dual redline, redline, and blackwall designs from Maxxis, BFGoodrich, and Michelin. This size deserves a closer look when the goal is to match a more performance-oriented or specialty appearance while staying with the proper 14-inch radial format.
185/75R14 is a metric radial tire size that uses a 185-millimeter nominal width, a 75-series aspect ratio, and a 14-inch wheel diameter. On the 1979 Oldsmobile Cutlass, it is a sub-model-specific fitment rather than a size shared across the whole model line. The available choices focus on traditional narrow whitewall styling, with options from Tornel, Maxxis, and Travelstar in several classic-oriented series. It is the size to confirm carefully when preserving the original fitment direction of a Cutlass that does not use the wider 195 or 205 section-width alternatives.
Sub-model fitment matters on the 1979 Oldsmobile Cutlass because the covered versions do not all share the same tire size. Before choosing a tire, confirm whether the car is a Cruiser, Cruiser (Diesel), V6, or V8 so the correct 14-inch radial size can be matched to the vehicle.

1979 Oldsmobile Cutlass Cruiser
The 1979 Oldsmobile Cutlass Cruiser uses either 195/75R14 or 205/70R14 radial tires, so size confirmation matters before comparing products. Once the exact fitment is established, selection can focus on whether the wagon calls for a whitewall, redline, raised white letter, or blackwall presentation.
The 1979 Oldsmobile Cutlass Cruiser (Diesel) uses 195/75R14 radial tires. That keeps the fitment decision straightforward, letting the buyer concentrate on choosing among wide whitewall and narrow whitewall options, tire series, and brand preferences within the correct size.
The 1979 Oldsmobile Cutlass V6 uses either 185/75R14 or 195/75R14 radial tires. That makes it especially important to verify the exact wheel-and-tire setup on the car before selecting a replacement, particularly if appearance, ride height, or prior changes may have altered what is currently installed.
The 1979 Oldsmobile Cutlass V8 uses either 195/75R14 or 205/70R14 radial tires. After confirming which size belongs on the car, the buyer can sort through a wider mix of sidewall styles and tire series, from traditional whitewalls to more assertive redline or raised white letter choices.

Tire Size & Fitment
What tire size fits a 1979 Oldsmobile Cutlass?
A 1979 Oldsmobile Cutlass can use 185/75R14, 195/75R14, or 205/70R14, depending on the exact sub-model. All three are radial tire sizes designed for 14-inch wheels, so the main fitment difference is not construction or wheel diameter, but which size belongs on the specific Cutlass configuration.
The next step is identifying whether the car is a Cruiser, Cruiser (Diesel), V6, or V8 and confirming what wheel-and-tire setup is actually on the vehicle today. That matters because decades of wheel changes, suspension work, or prior tire substitutions can leave a Cutlass wearing a different size than it originally used.
What size rim does a 1979 Oldsmobile Cutlass use?
The 1979 Oldsmobile Cutlass uses 14-inch rims with its primary tire fitments. The applicable sizes on this model are 185/75R14, 195/75R14, and 205/70R14, and each one shares the same 14-inch rim diameter even though the section width and profile differ by application.
Wheel diameter is only part of the check, so it still helps to verify the actual wheel width before choosing among available tires. Some products in these sizes call for different rim-width ranges, and an older Cutlass may have replacement wheels that affect how well a given tire size and sidewall style suits the car.
Do all 1979 Oldsmobile Cutlass sub-models use the same tire size?
No. The 1979 Oldsmobile Cutlass sub-models do not all use the same tire size. Depending on the version, the covered fitments include 185/75R14, 195/75R14, and 205/70R14, with some sub-models sharing more than one possible size rather than following a single universal specification.
That makes sub-model identification a necessary first step before comparing brands or sidewall treatments. It is also smart to inspect the wheels already on the car, since a Cutlass that has been altered over the years may not still be wearing the same size range associated with its original sub-model fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 1979 Oldsmobile Cutlass?
Start with the correct size for the exact 1979 Oldsmobile Cutlass sub-model, since this model can use 185/75R14, 195/75R14, or 205/70R14. From there, compare construction details, rim-width requirements, sidewall style, brand, load figures where stated, and whether the tire’s visual character matches the way the car is being restored or driven.
A Cutlass built for a traditional late-1970s look may point toward whitewall options, while another car may suit redline, raised white letter, or blackwall styling better. It also helps to check the wheel width and current clearance on the vehicle, especially if it has aftermarket wheels or a stance change that affects how the tire sits.
What sidewall styles are available for 1979 Oldsmobile Cutlass tires?
Sidewall choices for the 1979 Oldsmobile Cutlass include wide whitewall, narrow whitewall, redline, dual redline, raised white letter, and blackwall, depending on the tire size. The broadest visual variety appears in 205/70R14, while 185/75R14 and 195/75R14 lean more heavily toward whitewall-style radial offerings.
That variety lets the tire do a lot of visual work on the car, especially on a 1979 body style where sidewall treatment can noticeably change the overall presentation. Once the correct size is confirmed, sidewall choice becomes one of the easiest ways to steer the Cutlass toward a cleaner stock-style look or a more assertive period-inspired stance.
What brands offer tires for the 1979 Oldsmobile Cutlass?
Tires for the 1979 Oldsmobile Cutlass are available from Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, and Michelin across the sizes used on this model. Brand availability varies by tire size, so the exact options depend on whether the car uses 185/75R14, 195/75R14, or 205/70R14.
Brand choice should come after size confirmation, not before. Once the correct fitment is settled, it becomes easier to compare which brands offer the sidewall treatment, tire series, rim-width compatibility, and general look that suit the Cutlass, whether the car is being maintained as a cruiser or refreshed with a more distinctive visual theme.
Restoration & Appearance
Which tire should I choose for a period-style 1979 Oldsmobile Cutlass?
A period-style 1979 Oldsmobile Cutlass starts with the correct sub-model tire size, then narrows by sidewall treatment and overall visual character. Whitewall radials are available in the 185/75R14 and 195/75R14 sizes, while 205/70R14 opens the door to whitewall, redline, dual redline, raised white letter, and blackwall options.
The best match depends on how the car is being presented rather than on one universal appearance rule. For a restoration-minded build, it helps to compare the car’s trim, wheel style, and historical references for that exact configuration so the tire complements the vehicle instead of pulling it toward a look from another era or theme.
How does tire construction affect the appearance of a restored 1979 Oldsmobile Cutlass?
On the 1979 Oldsmobile Cutlass, the primary fitments are already radial, so the visual difference comes less from switching construction and more from the tire’s profile, sidewall treatment, and brand presentation. A narrow whitewall, wide whitewall, redline, raised white letter, or blackwall can each change the car’s personality in a noticeable way.
That makes size and sidewall choice especially important during a restoration or cosmetic refresh. Even when the wheel diameter stays at 14 inches, a different section width or sidewall style can shift the Cutlass from formal and restrained to sporty and more aggressive, so appearance should be weighed alongside fitment and intended road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1979 Oldsmobile Cutlass?
Yes. Modifications can affect tire fitment on a 1979 Oldsmobile Cutlass even when the tire size itself is one of the correct 14-inch applications. Aftermarket wheels, wheel-width changes, altered offset, suspension lowering, spring replacement, or body and brake changes can all influence how a 185/75R14, 195/75R14, or 205/70R14 tire sits on the car.
That is why the vehicle should be checked as it exists today rather than judged only by year and model. Steering clearance, fender space, and wheel width all matter once a car has been changed, and those checks become even more important when moving to a wider section width within the same 14-inch rim diameter.
What should I inspect before driving a 1979 Oldsmobile Cutlass on new tires?
Before driving a 1979 Oldsmobile Cutlass on new tires, inspect the wheels for the correct 14-inch diameter and suitable width, then check overall tire clearance at the fenders, suspension, and steering components. It is also wise to look over the brakes, wheel bearings, lug hardware, and alignment condition so the new tires are not working against an existing problem.
Collector-era cars often sit for long periods, so roadworthiness matters as much as fresh rubber. Tire pressure should be set correctly, and the first drive should be used to watch for rubbing, pulling, vibration, or unusual noise. A short recheck afterward can catch clearance or hardware issues before they become larger problems.
How should tires on a collector 1979 Oldsmobile Cutlass be maintained?
Tires on a collector 1979 Oldsmobile Cutlass should be inspected regularly for air loss, uneven wear, sidewall cracking, cuts, bulges, and signs of age-related deterioration. That applies whether the car uses 185/75R14, 195/75R14, or 205/70R14, since low annual mileage does not prevent time and storage conditions from affecting the tire.
Storage habits matter on a car that is driven occasionally. Keeping the Cutlass away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and periodic pressure checks remain important even when the car is parked for extended periods. An occasional close visual inspection is a good habit before any cruise or highway trip.
