The 1980 Buick Skylark came from a period when compact American cars were balancing traditional Buick comfort with more modern packaging and road manners. Buyers looking after one today often want tires that suit both the car’s late-classic character and its exact trim level. Tire fitment on the 1980 Buick Skylark centers on two radial 13-inch sizes: 185/80R13 and 205/70R13, depending on the sub-model. Available choices range from blackwall to narrow whitewall and wide whitewall designs, with several distinct tire series represented. The key is confirming the exact Skylark version first, then choosing the tire look and specification that best matches restoration goals and intended road use.
Which Tire Size Is Right for The 1980 Buick Skylark
The 1980 Buick Skylark uses two primary tire sizes, and the right one depends on the exact sub-model. Both are radial tires for 13-inch rims, so the first step is confirming whether the car is a Base or aluminum-wheel variant using 185/80R13, or a Limited or Sport variant using 205/70R13 before comparing tire style, brand, and series.
185/80R13 is a metric radial size in which 185 refers to the tire’s nominal section width in millimeters, 80 is the aspect ratio, and 13 is the wheel diameter in inches. On the 1980 Buick Skylark, this size is a primary fitment for certain sub-models and keeps the selection focused on modern radial construction. Available choices include Maxxis, BFGoodrich Silvertown Radial, and Coker Classic Star Series, with narrow whitewall and wide whitewall sidewall treatments. This size makes sense for owners who want to stay with the correct primary fitment while choosing an appearance that suits the car’s presentation.
Fit(s): Limited, Limited w/aluminum wheels, Sport, and Sport w/aluminum wheels
Construction: Radial|Rim: 13 in
205/70R13 is a metric radial size with a 205-millimeter nominal section width, a 70-series profile, and a 13-inch rim diameter. On the 1980 Buick Skylark, this size is used on specific sub-models, so it should be matched to the car’s actual trim and wheel setup rather than assumed across the entire model line. The available product in this size is a Michelin XDX-B blackwall radial, which gives this fitment a distinct product character compared with the whitewall options in 185/80R13. It is the size to evaluate when the vehicle falls into the Limited or Sport-oriented fitment group.
Sub-model fitment matters on the 1980 Buick Skylark because tire size is not the same across the full range. Some versions use 185/80R13, while others use 205/70R13, so identifying the exact Skylark trim and wheel configuration should come before comparing tires.

1980 Buick Skylark Base
The 1980 Buick Skylark Base uses the 185/80R13 radial tire size. That keeps selection centered on choosing among available radial products and deciding whether a narrow whitewall or wide whitewall better suits the car’s intended look.
The 1980 Buick Skylark Limited uses the 205/70R13 radial tire size. Tire selection here is more about confirming the correct trim fitment and matching the existing wheel setup than choosing between multiple sidewall styles.
The 1980 Buick Skylark Limited w/aluminum wheels also uses 205/70R13 radial tires. Owners should still confirm the wheels on the car today, especially if it has been changed over time, before settling on a replacement tire.
The 1980 Buick Skylark Sport uses the 205/70R13 radial size. That makes correct trim identification important first, then the focus shifts to selecting a tire that suits the car’s current road use and wheel condition.
The 1980 Buick Skylark Sport w/aluminum wheels uses 205/70R13 radials. For this version, the main task is confirming the car still carries the proper 13-inch wheel setup before replacing worn or aged tires.
The 1980 Buick Skylark w/aluminum wheels uses the 185/80R13 radial size. Once that fitment is confirmed, the meaningful choice becomes the tire’s visual presentation, especially between narrow whitewall and wide whitewall styles.
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.

Tire Size & Fitment
What tire size fits a 1980 Buick Skylark?
A 1980 Buick Skylark uses either 185/80R13 or 205/70R13, depending on the sub-model. The Base and Skylark w/aluminum wheels use 185/80R13, while the Limited, Limited w/aluminum wheels, Sport, and Sport w/aluminum wheels use 205/70R13. Both are radial tire fitments on 13-inch rims.
The practical difference is that trim identification comes first before comparing brands or sidewall styles. A Skylark that has had wheel changes over the years should be checked carefully, since the tire size should match both the car’s sub-model fitment and the actual wheels currently installed.
What size rim does a 1980 Buick Skylark use?
Both primary tire sizes for the 1980 Buick Skylark use a 13-inch rim diameter. The 185/80R13 and 205/70R13 fitments are both built around 13-inch wheels, so rim diameter stays consistent even though the tire sizes vary by sub-model.
Rim diameter is only part of the check. Width also matters, especially when comparing available products, since the 185/80R13 and 205/70R13 offerings do not share the same rim-width range. Measuring the wheels already on the car is worthwhile if the vehicle’s history includes aftermarket changes or replacement wheels.
Do all 1980 Buick Skylark sub-models use the same tire size?
No, the 1980 Buick Skylark does not use one tire size across every sub-model. Some versions use 185/80R13, while others use 205/70R13, so the exact trim level determines which primary fitment applies to the car.
That variation affects more than just the numbers on the sidewall. It changes which products are available, what sidewall styling can be chosen, and which rim-width specifications need to be checked. Sorting out the exact Skylark version first helps avoid choosing a tire that belongs to a different trim group.
Choosing the Right Tire
What should I consider when choosing a 185/80R13 tire for a 1980 Buick Skylark?
Start by confirming that the car is one of the 1980 Buick Skylark sub-models that uses 185/80R13. In this size, the main differences come from brand, tire series, sidewall style, rim-width specification, and load rating details rather than a change in basic construction, since all available options are radial.
Appearance plays a major role here because 185/80R13 is available in narrow whitewall and wide whitewall form. A more restoration-oriented car may call for one look, while a driver-focused car may simply need the right size and a compatible wheel width. Checking the existing wheel before purchase keeps the choice grounded in actual fitment.
What sidewall styles are available for 1980 Buick Skylark tires?
Sidewall style depends on which 1980 Buick Skylark tire size the car uses. In 185/80R13, available styles include narrow whitewall and wide whitewall. In 205/70R13, the available product is a blackwall radial, so sidewall appearance is tied closely to the vehicle’s specific fitment.
That means sidewall choice is not just a cosmetic add-on across the whole model line. A buyer with a Base or aluminum-wheel Skylark using 185/80R13 has more visual flexibility, while a Limited or Sport using 205/70R13 has a more focused product path. Matching the tire’s look to the car’s character usually starts with the correct size.
What brands offer tires for the 1980 Buick Skylark?
Available 1980 Buick Skylark tire brands include Maxxis, BFGoodrich, Coker Classic, and Michelin. The brand mix depends on the tire size: 185/80R13 has options from Maxxis, BFGoodrich, and Coker Classic, while 205/70R13 is represented by Michelin.
Brand alone should not drive the decision. The better comparison is between the correct size for the car, the tire series offered in that size, sidewall styling, and wheel compatibility. Once the proper Skylark sub-model fitment is confirmed, the brand list becomes more useful because it reflects the products that actually match that configuration.
Restoration & Appearance
Which tire should I choose for a period-style 1980 Buick Skylark?
A period-style 1980 Buick Skylark tire choice starts with the correct original fitment pattern for the specific sub-model: either 185/80R13 or 205/70R13. From there, the visual direction changes by size, since 185/80R13 offers narrow whitewall and wide whitewall presentations, while 205/70R13 is available as a blackwall radial.
That makes sub-model accuracy especially important on a restoration-minded car. Owners aiming for a particular showroom-era look should compare the tire’s sidewall treatment with photos, sales literature, marque-club references, or the car’s own history. The right size comes first, then the appearance details can be chosen more confidently.
Does correct tire fitment matter for a 1980 Buick Skylark restoration?
Correct tire fitment matters on a 1980 Buick Skylark restoration because the model used more than one primary tire size. Choosing between 185/80R13 and 205/70R13 is not just a cosmetic decision; it affects whether the car reflects the proper sub-model fitment and whether the available sidewall styles align with the intended finished look.
It also affects the overall impression of the car once the restoration is complete. A whitewall-equipped fitment and a blackwall-equipped fitment create very different visual results. Confirming the trim level, wheel setup, and restoration goal before selecting tires helps keep the car’s stance and presentation appropriate to the version being restored.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 Buick Skylark?
Yes, modifications can affect tire fitment on a 1980 Buick Skylark even when the correct original tire size is known. Wheel width changes, aftermarket wheels, altered ride height, suspension work, or body repairs can all influence how a 185/80R13 or 205/70R13 tire sits and clears the car.
A modified Skylark should be checked at the wheel, not judged only by the factory sub-model fitment. Tire-to-fender clearance, steering clearance, and wheel dimensions all deserve attention before replacement. That is especially important when the car no longer carries its original wheels or has been updated over the years.
What should I inspect before driving a 1980 Buick Skylark on new tires?
Before driving a 1980 Buick Skylark on new tires, inspect the wheels for correct diameter and width, verify proper inflation, and make sure the tires match the car’s sub-model fitment. It is also worth checking brake and suspension condition, since a new tire cannot compensate for worn hardware elsewhere on the vehicle.
A short, careful road check is smart after installation. Listen for rubbing, watch for vibration, and confirm the car tracks properly at neighborhood speeds before moving into regular use. On a collector-era car that may sit for long periods, rechecking air pressure after the first few drives is a sensible extra step.
How should 1980 Buick Skylark tires be maintained?
1980 Buick Skylark tires should be maintained with regular pressure checks, visual inspections, and periodic evaluation of age and condition. Even when tread looks acceptable, a low-use collector car can develop sidewall cracking, flat spotting, or internal aging that makes the tires less suitable for steady road use.
Storage conditions matter almost as much as mileage. Keeping the car away from prolonged sun, ozone sources, and damp conditions helps preserve the tires, especially on a vehicle that is driven seasonally. Any sign of bulges, cuts, persistent air loss, or uneven wear should be investigated before taking the car on longer trips.
