The 1985 Chevrolet Impala came at the end of the big rear-wheel-drive Chevrolet sedan era, when full-size American cars still balanced comfort, long-wheelbase ride quality, and unmistakably traditional proportions. For many owners, that makes tire choice part fitment decision and part appearance decision. This Impala uses radial tires on 15-inch rims, with 205/75R15 and 225/70R15 fitments depending on configuration. That opens the door to very different looks, from whitewall styles to redlines, raised white letters, and blackwall performance-oriented presentations. The right choice starts with confirming the exact sub-model and wheel setup, then matching the tire's construction, stance, and sidewall style to the way the car will be driven and presented.
Which Tire Size Is Right for The 1985 Chevrolet Impala
The 1985 Chevrolet Impala uses two primary tire sizes, and both are radial tires for 15-inch rims. The first step is confirming whether the car is a Base model or a w/Sport Suspension car, since the sport-suspension configuration uses the wider 225/70R15 fitment. Once that is settled, the decision becomes choosing the right sidewall style, tire series, and overall look for the way the car is restored or driven.
205/75R15 is a metric radial size in which 205 identifies nominal section width in millimeters, 75 is the aspect ratio, R marks radial construction, and 15 is the wheel diameter in inches. On the 1985 Chevrolet Impala, this size suits a traditional full-size sedan presentation and keeps the fitment in a modern radial format. Available choices include BFGoodrich, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar, with sidewall treatments ranging from narrow and wide whitewalls to goldline and redline. This size is worth considering when the car uses the standard fitment and the goal is to balance proper dimensions with a distinctly period-style sidewall appearance.
225/70R15 is also a metric radial size, with a 225-millimeter nominal section width, a 70-series profile, radial construction, and a 15-inch rim diameter. On the 1985 Chevrolet Impala, this wider radial fitment is especially important to confirm on w/Sport Suspension cars and may also appear on certain Base-model applications. Product choices cover several visual directions, including raised white letter, blackwall, redline, pin-white-stripe, narrow whitewall, and wide whitewall styles from brands such as Goodyear, Cooper, Michelin, BFGoodrich, and Maxxis. This size makes the most sense when the car's configuration and wheel setup call for the broader 15-inch radial package.
Sub-model fitment matters on the 1985 Chevrolet Impala because tire size is not identical across every configuration. The Base model can use either of the two radial sizes, while the w/Sport Suspension version centers the decision on the wider 225/70R15 fitment.

1985 Chevrolet Impala Base
The 1985 Chevrolet Impala Base uses radial tires on 15-inch rims and can be found with either 205/75R15 or 225/70R15. That makes wheel verification especially important before ordering, after which the buyer can focus on sidewall style, tire series, and the overall visual character that best suits the car.
The 1985 Chevrolet Impala w/Sport Suspension uses the 225/70R15 radial fitment on a 15-inch rim. That narrows the size decision, but there is still meaningful choice in sidewall presentation, from raised white letters to whitewall and redline styles, depending on whether the car leans more toward performance flavor or traditional full-size appearance.
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 1985 Chevrolet Impala tire questions usually come down to size selection, sub-model fitment, 15-inch rim compatibility, sidewall style, and choosing between more traditional whitewall looks and sportier radial presentations.
Tire Size & Fitment
What tire size fits a 1985 Chevrolet Impala?
The 1985 Chevrolet Impala uses two primary tire sizes: 205/75R15 and 225/70R15. Both are radial sizes for 15-inch rims. The Base model can use either size, while the 1985 Chevrolet Impala w/Sport Suspension uses 225/70R15.
The practical step is confirming the exact sub-model and the wheels currently on the car before choosing a tire. Since the Base model appears with more than one fitment, checking the existing tire size and wheel width helps prevent choosing a radial that matches the year and model name but not the actual setup on the car.
What size rim does a 1985 Chevrolet Impala use?
The 1985 Chevrolet Impala uses a 15-inch rim with both of its primary tire sizes. That applies to the 205/75R15 fitment and the 225/70R15 fitment, both of which are radial tires built around a 15-inch wheel diameter.
Rim diameter is only part of the fitment picture, so it is smart to verify wheel width as well before selecting a tire. A 15-inch wheel can still vary in width from one car to another, especially if the Impala has replacement wheels, and that can affect which of the available radial products is the better match.
Why does the 1985 Chevrolet Impala have more than one tire size?
More than one tire size appears on the 1985 Chevrolet Impala because fitment varies by configuration. The Base model can use either 205/75R15 or 225/70R15, while the w/Sport Suspension version uses 225/70R15.
That means the model name alone is not always enough to choose a tire. The safest approach is to confirm the exact sub-model, then compare the wheels already on the car with the tire size being replaced. This matters even more on older full-size cars that may have had wheel changes, suspension work, or appearance-focused updates over the years.
Choosing the Right Tire
What should I consider when choosing a 205/75R15 or 225/70R15 tire for a 1985 Chevrolet Impala?
Start with the correct size for the car's actual configuration, since the 1985 Chevrolet Impala uses both 205/75R15 and 225/70R15 depending on sub-model and setup. After size is settled, compare construction, sidewall style, tire series, and rim-width compatibility within that size.
Appearance usually drives the next decision on an Impala of this era. Some owners want a traditional whitewall look, while others prefer redlines, goldlines, blackwalls, or raised white letters. Matching the tire's visual character to the car's trim, wheel style, and intended use often matters just as much as the raw size code.
What sidewall styles are available for 1985 Chevrolet Impala tires?
1985 Chevrolet Impala tires are available with several sidewall treatments, including wide whitewall, narrow whitewall, redline, goldline, blackwall, pin-white-stripe, and raised white letter designs. The exact selection depends on whether the car uses 205/75R15 or 225/70R15.
That variety makes sidewall style a major part of the buying decision for this car. A whitewall can reinforce the Impala's formal full-size character, while redline or raised white letter tires push the look in a sportier direction. Once the correct size is confirmed, sidewall choice becomes one of the clearest ways to shape the car's finished presentation.
What brands offer tires for the 1985 Chevrolet Impala?
Tires for the 1985 Chevrolet Impala are available from BFGoodrich, Goodyear, Cooper, Michelin, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar. Brand availability depends on the tire size, with some brands concentrated in 205/75R15 and others appearing in 225/70R15.
Brand choice is best used as one comparison point rather than the only one. The more useful approach is to narrow the search by correct size first, then compare the tire series, sidewall treatment, and wheel-width suitability within that brand mix. That keeps the decision focused on fitment and appearance instead of relying on the brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Chevrolet Impala?
A period-style 1985 Chevrolet Impala tire starts with using the correct radial size for the car's actual configuration, either 205/75R15 or 225/70R15. From there, many owners lean toward whitewall styles for a more traditional full-size sedan presentation, though redline, goldline, and raised white letter options are also available.
The best visual match depends on how the car is being presented. A formal stock-appearing sedan often looks more at home on narrow or wide whitewalls, while a more personalized car may suit sportier sidewalls. When exact originality matters, comparing the finished car against marque references and period photos is a smart final check.
How does tire construction affect the appearance of a restored 1985 Chevrolet Impala?
On the 1985 Chevrolet Impala, the primary fitments are already radial, so the appearance decision is less about changing construction and more about choosing the right radial style. Whitewall width, stripe treatment, letter style, and overall tread presentation do more to shape the restored look than construction changes alone.
That makes the sidewall a major styling tool on this car. A wide whitewall can give the Impala a more formal, traditional presence, while an RWL or redline treatment creates a more assertive late-classic look. Keeping the correct size and 15-inch rim relationship intact helps those appearance choices look intentional rather than mismatched.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Chevrolet Impala?
Yes. Modifications can change tire fitment on a 1985 Chevrolet Impala even when the tire size seems correct on paper. Aftermarket wheels, altered wheel width, changed offset, lowering, suspension work, or body changes can all affect how a 205/75R15 or 225/70R15 tire sits and clears.
A modified Impala should be checked at the wheel opening and through the steering range before settling on a tire. Clearance at the fender, suspension, and inner wheelhouse matters just as much as the size code itself. That is especially important on a car that has already moved away from its original wheel and suspension relationship.
What should I inspect before driving a 1985 Chevrolet Impala on new tires?
Before driving a 1985 Chevrolet Impala on new tires, inspect the wheels for correct diameter and condition, confirm proper inflation, and look over suspension and steering components for looseness or wear. It also helps to recheck lug torque and make sure the tires have adequate clearance at full steering lock.
Collector-era full-size cars can hide age-related issues even when they are driven infrequently. A fresh set of tires cannot compensate for weak shocks, worn bushings, bent wheels, or alignment problems. Taking a short test drive and then reinspecting for rubbing, air loss, or irregular contact marks is a sensible final step.
How should 205/75R15 or 225/70R15 tires on a collector 1985 Chevrolet Impala be maintained?
205/75R15 and 225/70R15 tires on a collector 1985 Chevrolet Impala should be kept at proper pressure, inspected regularly for cracking, bulges, cuts, and uneven wear, and protected from long periods of sun, moisture, and ozone exposure. Occasional movement also helps prevent flat-spotting during long storage periods.
Cars that spend much of their time parked deserve extra attention because age and storage conditions can matter as much as tread depth. Checking pressure before each drive, watching for slow air loss, and inspecting the sidewalls closely are simple habits that help preserve both safety and the finished appearance of a well-kept Impala.
