The 1994 Buick Roadmaster came at the end of the traditional full-size American sedan and wagon era, pairing big-body comfort with rear-wheel-drive proportions that still appeal to Buick enthusiasts and collectors. Whether the goal is preserving a long-roof Estate Wagon or keeping a sedan true to its original character, tire selection shapes both stance and road manners. This Roadmaster uses radial tires only, with 235/70R15 on Base and Limited models and 225/75R15 on the Estate Wagon, all on 15-inch rims. Available choices include blackwall, whitewall, redline, and raised white letter styles across several tire series. The key is matching the correct size to the exact sub-model, then choosing the appearance and road-use character that suit the car.
Which Tire Size Is Right for The 1994 Buick Roadmaster
Two tire sizes apply to the 1994 Buick Roadmaster, and the right one depends on the exact sub-model. Both are radial tires for 15-inch rims, but Base and Limited models use one size while the Estate Wagon uses another, so identifying the vehicle configuration comes first before comparing brands, sidewall styles, and tire series.
A 235/70R15 is a metric radial tire with a 235-millimeter nominal section width, a 70-series profile, and a fitment for a 15-inch wheel. On the 1994 Buick Roadmaster, this is the primary size for the Base and Limited sub-models, making it the standard sedan fitment to match first. Product choice is broad in this size, with options from Cooper, Avon, BFGoodrich, and Michelin in blackwall, narrow whitewall, wide whitewall, redline, and raised white letter styles. That variety makes this size especially useful for buyers balancing traditional Buick appearance, sportier sidewall treatment, and wheel-width compatibility.
A 225/75R15 is a metric radial tire with a 225-millimeter nominal section width, a taller 75-series profile, and a 15-inch rim diameter. On the 1994 Buick Roadmaster, this size belongs to the Estate Wagon, so it should be selected only for that sub-model or for a vehicle already confirmed to use that wheel-and-tire setup. Available choices lean toward traditional presentation, with BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar offerings in narrow and wide whitewall styles. This size is the one to evaluate when wagon stance, load-minded touring use, and period-style sidewall appearance matter most.
Sub-model fitment matters on the 1994 Buick Roadmaster because the sedan and wagon do not use the same tire size. Base and Limited models share one radial size, while the Estate Wagon uses a different 15-inch radial, so confirming the exact version is the first step before comparing products.

1994 Buick Roadmaster Base
The 1994 Buick Roadmaster Base uses the same radial tire fitment as the Limited model, so sedan owners can focus on choosing the right product within that size. The main decision becomes sidewall style, tire series, and wheel-width compatibility rather than sorting through multiple primary fitments.
The 1994 Buick Roadmaster Estate Wagon uses its own radial tire size, distinct from the sedan models. That makes wagon identification important before purchase, especially for owners trying to preserve the proper stance or choosing among narrow and wide whitewall options.
The 1994 Buick Roadmaster Limited shares its radial tire size with the Base model, keeping sedan fitment straightforward. Tire selection then comes down to whether the goal is a more formal Buick look with whitewalls, a blackwall touring presentation, or a sportier raised white letter or redline treatment.
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.
Best 1994 Buick Roadmaster Tires for Sale

Common 1994 Buick Roadmaster tire questions usually come down to the correct sub-model size, 15-inch rim fitment, appearance choices such as whitewalls or RWL, and what to inspect before putting a full-size Buick sedan or wagon back on the road.
Tire Size & Fitment
What tire size fits a 1994 Buick Roadmaster?
The 1994 Buick Roadmaster uses two tire sizes, depending on sub-model. Base and Limited models use 235/70R15 radial tires, while the Estate Wagon uses 225/75R15 radial tires. Both fitments are built around a 15-inch rim, but the size itself is not shared across every Roadmaster configuration.
The first step is confirming whether the vehicle is a sedan or an Estate Wagon, then checking that the wheels still match the intended tire size. Many surviving Roadmasters have been updated over the years, so it is worth confirming the actual wheel setup on the car before choosing a sidewall style or tire series.
What size rim does a 1994 Buick Roadmaster use?
The 1994 Buick Roadmaster uses a 15-inch rim with both of its primary tire sizes. The 235/70R15 used on Base and Limited models and the 225/75R15 used on the Estate Wagon are both designed around a 15-inch wheel diameter, so rim diameter remains consistent even though the tire sizes differ.
That consistency helps narrow the fitment decision, but wheel diameter alone does not settle the whole question. It is still smart to confirm which sub-model the car is, verify the actual wheel width, and check whether aftermarket wheels have changed the original tire-and-rim relationship before making a final selection.
Do all 1994 Buick Roadmaster sub-models use the same tire size?
No, all 1994 Buick Roadmaster sub-models do not use the same tire size. The Base and Limited share 235/70R15 radial tires, while the Estate Wagon uses 225/75R15 radial tires. That means Roadmaster fitment is split between sedan and wagon applications rather than being universal across the model line.
This matters because the available products and sidewall treatments differ by size, and the wrong size can alter the way the car sits or clears the body. Matching the tire to the exact sub-model first makes the rest of the buying process much easier, especially when comparing whitewall, blackwall, or more performance-oriented options.
Choosing the Right Tire
What should I consider when choosing a 235/70R15 tire for a 1994 Buick Roadmaster?
A 235/70R15 tire for a 1994 Buick Roadmaster should first match the correct sedan application, since this size belongs on Base and Limited models. From there, the most meaningful differences are sidewall appearance, brand, tire series, and wheel-width compatibility, with choices ranging from blackwall and narrow whitewall to wide whitewall, redline, and raised white letter designs.
The right pick depends on how the car is used and how it should look. A restoration-oriented sedan may call for a traditional whitewall or redline presentation, while a more driver-focused car may lean toward blackwall or RWL styling. Wheel width should always be checked before finalizing the choice within this size.
What sidewall styles are available for 1994 Buick Roadmaster tires?
1994 Buick Roadmaster tires are available in several sidewall styles, including blackwall, narrow whitewall, wide whitewall, redline, and raised white letter. The exact mix depends on size, with 235/70R15 offering the broadest visual range and 225/75R15 leaning more toward traditional whitewall treatments suited to a large Buick sedan or wagon presentation.
Sidewall style has a major effect on the car's character even when the tire size stays the same. A wide whitewall gives a more formal, period-style look, redline adds a sportier vintage touch, and RWL creates a more performance-oriented appearance. Once the correct size is confirmed, sidewall treatment becomes one of the easiest ways to tailor the Roadmaster's stance.
What brands offer tires for the 1994 Buick Roadmaster?
Tires for the 1994 Buick Roadmaster are available from Cooper, Avon, BFGoodrich, Michelin, Coker Classic, American Classic, Maxxis, and Travelstar. Brand availability depends on the tire size, with 235/70R15 and 225/75R15 each carrying their own mix of product lines, sidewall styles, and wheel-width specifications.
Brand choice is best treated as part of a broader comparison rather than the only decision point. Once the correct size is established for the sub-model, compare the tire series, sidewall presentation, and wheel-width range that best align with the way the Roadmaster will be driven and the visual impression the vehicle should maintain.
Restoration & Appearance
Which tire should I choose for a period-style 1994 Buick Roadmaster?
A period-style 1994 Buick Roadmaster starts with the correct size for the sub-model: 235/70R15 for Base and Limited sedans or 225/75R15 for the Estate Wagon. After that, a traditional whitewall treatment often gives the car the most formal Buick presentation, while blackwall, redline, or raised white letter options can shift the look in a different direction.
Exact originality can vary by how an individual car was equipped, so appearance-minded buyers should compare the tire to period photos, build records, or marque-club guidance when detail matters. Staying with the right size first keeps the proportions believable, then sidewall style and tire series help refine the final restoration-oriented look.
How does tire construction affect the appearance of a restored 1994 Buick Roadmaster?
On a 1994 Buick Roadmaster, construction does not create a bias-ply versus radial decision because the primary fitments are radial tires. Appearance changes come more from the tire's profile, sidewall treatment, and series than from switching between older and newer construction types, since this Roadmaster already belongs to the radial era.
That means a restored Roadmaster can look noticeably different with the same basic size depending on whether it wears blackwalls, narrow whitewalls, wide whitewalls, redlines, or raised white letters. Keeping the proper sub-model size in place preserves the vehicle's proportions, while the sidewall style does most of the work in shaping the final visual character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1994 Buick Roadmaster?
Yes, modifications can affect tire fitment on a 1994 Buick Roadmaster even when the original tire size is known. Aftermarket wheels, altered wheel widths, suspension changes, ride-height adjustments, or body modifications can all change how a 235/70R15 or 225/75R15 tire sits in the wheel opening and how much clearance remains during steering or suspension travel.
That is why the actual setup on the car matters as much as the original fitment guide. A Roadmaster with non-stock wheels should have its wheel diameter, wheel width, and visible clearance checked before a tire is chosen. Confirming those basics helps avoid selecting a correct-on-paper size that no longer suits the vehicle's present configuration.
What should I inspect before driving a 1994 Buick Roadmaster on new tires?
Before driving a 1994 Buick Roadmaster on new tires, inspect the wheels for damage, confirm the tires are inflated properly, and make sure there is no rubbing at the fenders, suspension, or steering components. It is also wise to check lug hardware, valve stems, and overall suspension condition so the new tires are not being asked to work around avoidable mechanical issues.
A large, low-use collector sedan or wagon can hide problems that do not show up until road speed increases. Side-to-side clearance, unusual air loss, and vibration should all be checked early, especially after the first few miles. A brief reinspection after initial driving helps confirm that the Roadmaster is settling onto the new tires as expected.
How should tires on a collector 1994 Buick Roadmaster be maintained?
Tires on a collector 1994 Buick Roadmaster should be maintained with regular pressure checks, routine visual inspection, and periodic movement of the car so the tires are not left under load in one position for long stretches. Even a Roadmaster that sees limited mileage can develop age-related cracking, flat spotting, or slow air loss if it spends long periods parked.
Storage conditions matter almost as much as mileage on a full-size Buick kept for hobby use. Keeping the car away from prolonged sun, excess heat, moisture, and ozone sources can help preserve tire condition. Before any longer drive, inspect tread and sidewalls closely and make sure the tires still suit the vehicle's current wheels and suspension setup.
