The 1986 Oldsmobile Cutlass Supreme sits squarely in the last strong years of the rear-wheel-drive G-body era, a platform that remains popular with restorers, lowrider builders, and owners who want a comfortable 1980s cruiser with unmistakable Oldsmobile character. Tire selection matters because this Cutlass Supreme uses 14-inch radial fitments in either 195/75R14 or 205/70R14. That gives owners a meaningful choice between traditional whitewall presentations, sportier sidewall treatments like redline or raised white letter, and several distinct radial series. The right decision comes down to the car’s exact setup, the look you want, and confirming wheel compatibility before changing size or style.
Which Tire Size Is Right for The 1986 Oldsmobile Cutlass Supreme
The 1986 Oldsmobile Cutlass Supreme uses two primary tire sizes, and both are radial fitments on 14-inch rims. Because both the Base and Brougham can use either size, the first step is confirming which size is already on the car or which wheel-and-tire setup you intend to keep. From there, the decision shifts to sidewall style, tire series, and overall appearance rather than construction type.
195/75R14 is a metric radial size where 195 identifies the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On the 1986 Oldsmobile Cutlass Supreme, this size supports a more traditional 14-inch radial fitment and appears in several whitewall-oriented choices. Available options include Coker Classic, Tornel, Maxxis, and Travelstar, with wide whitewall and narrow whitewall sidewall treatments across multiple series. This size makes sense for owners aiming for a more classic boulevard look while staying with the proper radial format.
205/70R14 is a metric radial size with a 205-millimeter nominal section width, a 70-series profile, radial construction, and a 14-inch rim diameter. On the 1986 Oldsmobile Cutlass Supreme, it offers another primary radial fitment with a broader range of visual personalities than the narrower size. Available choices include Maxxis, BFGoodrich, and Michelin, with narrow whitewall, raised white letter, redline, dual-redline, and blackwall presentations across several tire series. This size is worth considering when the goal is a slightly sportier or more customized period-style appearance on the correct rim diameter.
Tire fitment is straightforward across the covered 1986 Oldsmobile Cutlass Supreme sub-models because both the Base and Brougham use the same two 14-inch radial sizes. Checking the sub-model still matters, but the bigger question is which of the two approved sizes and sidewall styles best matches the car’s current wheel setup and intended look.

1986 Oldsmobile Cutlass Supreme Base
The 1986 Oldsmobile Cutlass Supreme Base uses the same two primary radial tire sizes as the broader model range, both on 14-inch rims. That keeps the focus on confirming which size is on the car now and then choosing among whitewall, blackwall, redline, or raised white letter options.
The 1986 Oldsmobile Cutlass Supreme Brougham shares the same 14-inch radial fitment pattern, with both primary tire sizes applying here as well. Tire selection is less about a trim-specific size difference and more about preserving the car’s intended stance and choosing the sidewall treatment that suits the build.
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.

Common questions for the 1986 Oldsmobile Cutlass Supreme usually center on choosing between 195/75R14 and 205/70R14, understanding 14-inch rim fitment, and selecting the right radial style for restoration, cruising, or a more customized 1980s look.
Tire Size & Fitment
What tire size fits a 1986 Oldsmobile Cutlass Supreme?
The 1986 Oldsmobile Cutlass Supreme uses two primary tire sizes: 195/75R14 and 205/70R14. Both are radial tire sizes designed for 14-inch rims, and both appear across the Cutlass Supreme range, including the Base and Brougham sub-models.
That means the main fitment question is not bias-ply versus radial, but which of the two 14-inch sizes matches the car’s current wheel and intended look. Checking the size already on the vehicle, the wheel width, and the available clearance helps keep the replacement choice aligned with the car’s present setup.
What size rim does a 1986 Oldsmobile Cutlass Supreme use?
The supported tire sizes for the 1986 Oldsmobile Cutlass Supreme both use a 14-inch rim diameter. That applies to 195/75R14 and 205/70R14, so the rim diameter remains consistent even though the section width and profile differ between the two tire sizes.
Rim diameter is only one part of the fitment picture, so it is still worth confirming the actual wheel on the car before ordering tires. A Cutlass Supreme with replacement wheels, altered wheel width, or a custom build may need closer attention to sidewall shape, clearance, and the tire maker’s approved rim-width range.
Do all 1986 Oldsmobile Cutlass Supreme sub-models use the same tire size?
The 1986 Oldsmobile Cutlass Supreme Base and Brougham share the same two primary tire sizes: 195/75R14 and 205/70R14. In other words, sub-model choice does not force a different rim diameter or a different tire construction, since both fitments are 14-inch radials.
Even with shared sub-model fitment, the car should still be checked as an individual vehicle. Owners often discover that a previous set of tires, replacement wheels, or appearance-driven changes influenced the current setup, so matching the tire size to the wheel and the stance you want is the smart next step.
Choosing the Right Tire
What should I consider when choosing a 1986 Oldsmobile Cutlass Supreme tire?
Start with the correct primary size for the car’s current setup, either 195/75R14 or 205/70R14, and keep the 14-inch rim diameter in view. From there, construction is simple because the available fitments are radial, so the real comparison shifts to sidewall style, tire series, brand, and wheel-width compatibility.
A restoration-minded Cutlass Supreme may lean toward whitewall options, while a more customized or sport-flavored build may call for blackwall, redline, dual-redline, or raised white letter styling. It also helps to compare load figures, product weights, and approved rim-width ranges so the tire suits both the car and its intended use.
What sidewall styles are available for 1986 Oldsmobile Cutlass Supreme tires?
Sidewall choices for the 1986 Oldsmobile Cutlass Supreme include wide whitewall, narrow whitewall, blackwall, redline, dual-redline, and raised white letter depending on the tire size selected. The 195/75R14 offerings lean toward whitewall presentations, while 205/70R14 adds sportier and more customized-looking sidewall treatments.
That variety makes the tire decision as much about appearance as fitment. A broad whitewall can reinforce a traditional boulevard look, while redline or raised white letter styling can shift the car toward a more performance-inspired 1980s personality, so the best choice depends on how the Cutlass Supreme is being finished and driven.
What brands offer tires for the 1986 Oldsmobile Cutlass Supreme?
Tires for the 1986 Oldsmobile Cutlass Supreme are available from Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, and Michelin across the two supported 14-inch radial sizes. Brand availability depends on the exact size, so the lineup is not identical between 195/75R14 and 205/70R14.
Brand choice should be evaluated alongside the tire’s series, sidewall style, and approved wheel fitment rather than by name alone. One product may suit a whitewall-focused cruiser, while another may better match a blackwall or redline look, so comparing the full specification and appearance package is more useful than chasing a label.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Oldsmobile Cutlass Supreme?
A period-style 1986 Oldsmobile Cutlass Supreme usually starts with the correct 14-inch radial size already suited to the car, either 195/75R14 or 205/70R14. From there, the most visually important choice is sidewall treatment, since available options range from wide and narrow whitewalls to blackwall, redline, dual-redline, and raised white letter styles.
The right look depends on how the car is being presented. A more formal cruiser often benefits from whitewall styling, while a sportier or personalized build may look more natural on redline or raised white letter tires, and buyers seeking exact originality should compare their selection against marque references and vehicle-specific historical documentation.
How does tire construction affect the appearance of a restored 1986 Oldsmobile Cutlass Supreme?
On the 1986 Oldsmobile Cutlass Supreme, construction is less of a visual dividing line than on earlier collector cars because the supported primary fitments are radial sizes. The appearance difference comes more from the tire’s proportions, sidewall design, and series character than from choosing between bias-ply and radial construction.
That puts the emphasis on selecting the right size and sidewall presentation for the restoration goal. A 195/75R14 with a whitewall can give a softer traditional look, while a 205/70R14 in blackwall, redline, or raised white letter form can create a more assertive 1980s stance without moving away from the correct radial format.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Oldsmobile Cutlass Supreme?
Yes, modifications can affect tire fitment on a 1986 Oldsmobile Cutlass Supreme even when the tire size itself is one of the correct primary options. Aftermarket wheels, different wheel widths, altered offset, suspension changes, or body adjustments can all change how a 195/75R14 or 205/70R14 sits in the wheel opening.
A modified car should be checked carefully before changing tires. Verifying wheel diameter and width, looking at steering and fender clearance, and comparing the tire maker’s approved rim-width range are worthwhile steps, especially on lowered cars or vehicles built for lowrider or custom use where small fitment changes can matter.
What should I inspect before driving a 1986 Oldsmobile Cutlass Supreme on new tires?
Before road use, inspect the wheels for damage, confirm the tire size matches the intended setup, and check that the tires are inflated properly for the application. It is also smart to look over suspension and steering components, because worn parts can affect how a newly mounted tire behaves on the car.
A short test drive should include attention to rubbing, pulling, vibration, and uneven ride behavior. Collector cars that spend long periods parked also deserve a close look at the old tires that came off, since unusual wear patterns, cracking, or repeated air loss can reveal alignment, wheel, or storage-related issues worth correcting first.
How should 195/75R14 or 205/70R14 tires on a collector 1986 Oldsmobile Cutlass Supreme be maintained?
Collector-car tire care starts with regular pressure checks, visual inspection, and keeping the tires clean and protected from long exposure to heat, sunlight, moisture, and ozone sources. On a 1986 Oldsmobile Cutlass Supreme, both supported tire sizes are radial, so maintenance centers on preserving condition and watching for age-related deterioration.
Even a lightly driven Cutlass Supreme should have its tires inspected for cracking, bulges, cuts, tread wear, and slow air loss before regular road use. Cars that sit for extended periods benefit from periodic movement and careful storage habits, since long stationary intervals can affect both ride quality and the overall health of the tire.
