The 1983 Buick Skylark came from a period when domestic midsize cars were moving fully into modern radial-tire sizing, and trim level could noticeably change the vehicle’s stance and tire presentation. That matters on this exact model, because 1983 Skylark fitment is split across three radial sizes: 185/80R13, 205/70R13, and 215/60R14. Custom and Limited models stay with a taller-profile 13-inch radial, while the Sport and T-Type step into wider, lower-profile combinations. Available choices also vary by brand and sidewall style, from blackwall and raised white letter looks to narrow and wide whitewalls. The key is matching the tire to the exact sub-model and wheel diameter before comparing appearance or road-use priorities.
Which Tire Size Is Right for The 1983 Buick Skylark
Three tire sizes apply to the 1983 Buick Skylark, and the correct one depends on the exact sub-model and wheel diameter. Two sizes use 13-inch rims, while the T-Type moves to a 14-inch rim, so the first step is confirming both the trim and the actual wheels on the car. Once that is settled, the decision becomes choosing the right radial tire style, brand, and sidewall treatment within the proper size.
185/80R13 is a metric radial size in which 185 identifies the nominal section width in millimeters, 80 is the aspect ratio, R indicates radial construction, and 13 is the rim diameter in inches. On the 1983 Buick Skylark, this size suits the taller-profile 13-inch setup used on certain sub-models and keeps the tire selection focused on traditional road-car proportions. Available choices include Maxxis, BFGoodrich, and Coker Classic offerings with narrow whitewall and wide whitewall treatments across different tire series. It is the right size to evaluate when preserving a more formal or restoration-oriented appearance on a Custom or Limited.
205/70R13 is a metric radial size with a 205-millimeter nominal width, a 70-series profile, radial construction, and a 13-inch rim diameter. Compared with the taller 185/80R13 format, this size points to a wider, lower-profile 13-inch fitment on the 1983 Buick Skylark. The available product in this size is a Michelin XDX blackwall from the Michelin XDX-B series, giving this fitment a distinctly road-focused and understated presentation. This is the size to confirm when the car is a Sport model or when a 13-inch wheel remains in place but the fitment is not the taller 185-series setup.
215/60R14 is a metric radial size where 215 is the nominal section width in millimeters, 60 is the aspect ratio, R marks radial construction, and 14 indicates rim diameter. On the 1983 Buick Skylark, this size is tied to a wider, shorter-profile fitment on a 14-inch wheel, giving it a different selection path than the 13-inch sizes. The available choice is a BFGoodrich Radial T/A with raised white letters in the Radial TA series, a look closely associated with period performance styling. This is the size to check carefully on a T-Type, especially if the car has ever had wheels changed over time.
Sub-model fitment on the 1983 Buick Skylark is not one-size-fits-all. Custom and Limited share the same radial size, while Sport and T-Type use different combinations, so confirming the exact trim is essential before choosing a tire.

1983 Buick Skylark Custom
The 1983 Buick Skylark Custom uses the 185/80R13 radial size on a 13-inch wheel. Tire selection here is mainly about choosing among available whitewall styles and radial series while keeping the correct overall fitment approach for the Custom’s setup.
The 1983 Buick Skylark Limited also uses the 185/80R13 radial size on a 13-inch wheel. That makes the choice less about size and more about sidewall presentation, brand, and whether a narrow or wide whitewall better suits the car’s intended appearance.
The 1983 Buick Skylark Sport uses the 205/70R13 radial size. Because this is a different 13-inch fitment than the Custom and Limited, the key step is confirming that the car still carries the proper wheel and tire combination before comparing product characteristics.
The 1983 Buick Skylark T-Type uses the 215/60R14 radial size on a 14-inch wheel. That makes wheel diameter confirmation especially important, and it also shifts the visual character toward a more performance-oriented tire presentation with raised white letters.
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 1983 Buick Skylark tire FAQs focus on the exact size for each sub-model, 13-inch versus 14-inch wheel fitment, radial tire choices, appearance differences, and the checks that matter before road use.
Tire Size & Fitment
What tire size fits a 1983 Buick Skylark?
The 1983 Buick Skylark uses three different radial tire sizes depending on sub-model: 185/80R13, 205/70R13, and 215/60R14. Custom and Limited models use 185/80R13, the Sport uses 205/70R13, and the T-Type uses 215/60R14.
That means the first step is identifying the exact trim and confirming the wheel diameter actually on the car. A Skylark that has had wheels changed over the years may no longer match its original sub-model setup, so checking the current rim size before selecting a tire helps prevent a mismatch in diameter, width, and overall fitment.
What size rim does a 1983 Buick Skylark use?
A 1983 Buick Skylark uses either a 13-inch or 14-inch rim, depending on sub-model. The 185/80R13 and 205/70R13 sizes mount on 13-inch wheels, while the 215/60R14 size uses a 14-inch wheel.
Wheel diameter is the quickest way to narrow the correct tire choice, but it is not the only measurement that matters. Rim width should also be checked against the tire being considered, especially if the car has aftermarket wheels or replacement steel wheels, since a correct diameter alone does not guarantee the right overall wheel-and-tire combination.
Do all 1983 Buick Skylark sub-models use the same tire size?
No. The 1983 Buick Skylark has sub-model-specific tire fitments. Custom and Limited share 185/80R13, the Sport uses 205/70R13, and the T-Type uses 215/60R14, so the tire size changes across the range.
That variation matters because the differences are not just cosmetic. The T-Type moves to a 14-inch wheel, while the Sport keeps a 13-inch wheel but uses a wider, lower-profile tire than the Custom and Limited. Matching the tire to the exact sub-model keeps the fitment process grounded in the vehicle’s intended wheel-and-tire package.
Choosing the Right Tire
What should I consider when choosing a tire for a 1983 Buick Skylark?
Start with the correct tire size for the exact 1983 Buick Skylark sub-model, then confirm the wheel diameter and rim width before comparing products. Since all primary fitments on this car are radial, the real choice is usually between brands, tire series, and sidewall style rather than between basic construction types.
A Custom or Limited owner may focus on whitewall appearance, while a Sport or T-Type owner may care more about a blackwall or raised white letter look. Load capacity, wheel compatibility, and the intended use of the car also matter, especially on a collector vehicle that may alternate between show use, weekend cruising, and longer drives.
What sidewall styles are available for 1983 Buick Skylark tires?
Sidewall choices for the 1983 Buick Skylark include narrow whitewall, wide whitewall, blackwall, and RWL, which means raised white letter. The available style depends on the tire size, so sidewall selection is tied directly to the sub-model and wheel setup rather than being interchangeable across all Skylark trims.
That gives the car noticeably different visual personalities. Whitewalls suit a more formal or restoration-oriented presentation on 185/80R13 applications, while blackwall and raised white letter styles align more naturally with Sport and T-Type themes. Once the correct size is confirmed, sidewall style becomes one of the most important appearance decisions on the page.
What brands offer tires for the 1983 Buick Skylark?
Tires for the 1983 Buick Skylark are available from Maxxis, BFGoodrich, Coker Classic, and Michelin, depending on the size. Brand availability is not identical across all fitments, so the exact choices depend on whether the car uses 185/80R13, 205/70R13, or 215/60R14.
That makes size confirmation especially important before comparing brands. A buyer looking at 185/80R13 can weigh several whitewall-oriented options, while 205/70R13 and 215/60R14 each follow a narrower product path. Comparing brand should come after the correct tire size, wheel diameter, and desired sidewall presentation have already been settled.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Buick Skylark?
A period-style choice for a 1983 Buick Skylark starts with the correct sub-model size and wheel diameter, then moves to the sidewall treatment that best matches the car’s intended character. On Custom and Limited models, 185/80R13 whitewall radials support a more traditional appearance, while the Sport and T-Type lean toward blackwall or raised white letter presentations.
The right visual result depends on whether the car is being preserved as a formal trim-level cruiser or given a sportier early-1980s look. Exact originality claims should be checked against marque references, surviving examples, and vehicle-specific historical documentation, especially if the goal is a highly accurate restoration rather than a broadly period-inspired presentation.
How does tire construction affect the appearance of a restored 1983 Buick Skylark?
On a 1983 Buick Skylark, the primary fitments are already radial, so construction choice is less about bias-ply versus radial appearance and more about the size, profile, and sidewall style used on the car. The visual difference comes mainly from whether the tire is a taller whitewall 13-inch fitment or a lower-profile blackwall or raised white letter setup.
That means a restored Skylark’s final look can shift noticeably even when the construction type stays the same. A Custom or Limited with wide whitewalls presents very differently from a T-Type on 215/60R14 raised white letters. Matching the tire’s profile and sidewall to the sub-model helps keep the finished car visually coherent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Buick Skylark?
Yes. Modifications can change tire fitment on a 1983 Buick Skylark, especially if the car has aftermarket wheels, altered suspension height, different wheel widths, or changes in offset. Those factors can affect how a 185/80R13, 205/70R13, or 215/60R14 tire sits within the wheel opening and how it clears steering and suspension components.
A car that no longer carries its original wheels should be checked carefully before any tire is chosen. Confirm the actual rim diameter, measure wheel width, and inspect for clearance at full steering lock and through suspension travel. That is particularly important on the T-Type, where the move to a 14-inch fitment separates it from the other Skylark trims.
What should I inspect before driving a 1983 Buick Skylark on new tires?
Before driving a 1983 Buick Skylark on new tires, inspect the wheels for damage, confirm lug hardware condition, and make sure the selected tire size matches the car’s sub-model and rim diameter. Tire pressure should be set appropriately, and the new tires should be checked for even seating and adequate clearance around the fenders and suspension.
A collector-era car also deserves a broader once-over before road use. Look at steering and suspension wear, check for alignment issues, and inspect the old tires that were removed for signs of rubbing or uneven wear that might point to a setup problem. Catching those issues early helps the new tires wear and behave more consistently.
How should tires on a collector 1983 Buick Skylark be maintained?
Tires on a collector 1983 Buick Skylark should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even a car that is driven infrequently can develop tire aging concerns, so sidewalls and tread should be examined for cracking, cuts, bulges, irregular wear, and slow air loss.
Storage conditions matter almost as much as mileage on a low-use Skylark. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires over time. It also makes sense to inspect the tires before each outing, since collector cars often sit longer between drives than modern daily transportation.
