The 1989 Isuzu Impulse came from an era when imported sport coupes were blending sharp styling, nimble road manners, and everyday usability into one compact package. It remains a distinctive late-1980s choice for owners who appreciate a less common Japanese performance car with genuine period character. For this model year, the 1989 Isuzu Impulse uses a 205/60R14 radial tire, which keeps the fitment conversation focused on getting the right metric radial size on a 14-inch wheel. That makes the main decision less about multiple fitments and more about choosing the right tire style, brand, and road-use priorities. Owners balancing preservation, appearance, and regular driving should start by confirming the wheel setup already on the car.
Which Tire Size Is Right for The 1989 Isuzu Impulse
The 1989 Isuzu Impulse uses one primary tire size: 205/60R14, and it is a radial fitment for a 14-inch rim. The Base sub-model shares that same size, so the key decision is not sorting through multiple factory sizes but choosing the right 205/60R14 tire for the car's current wheels, intended use, and overall presentation.
A 205/60R14 size uses a metric sizing system: 205 refers to the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 14 is the wheel diameter in inches. On the 1989 Isuzu Impulse, this is the primary radial fitment and reflects the more modern sizing conventions common by the late 1980s. For buyers, the focus is on selecting the right 205/60R14 tire while keeping wheel diameter and overall compatibility in view. Checking the actual wheel width and any past suspension or wheel changes is still important before settling on a replacement tire.
Sub-model fitment is straightforward for the 1989 Isuzu Impulse covered here. The available sub-model uses the same tire size, so selection is mainly about choosing the right 205/60R14 radial tire and confirming that the car still carries the correct 14-inch wheel setup.

1989 Isuzu Impulse Base
The 1989 Isuzu Impulse Base uses the same 205/60R14 radial fitment as the model core. That keeps tire selection focused on finding the right metric radial in the proper size while verifying the wheels on the car have not been changed over time.
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.
Frequently Asked Questions
Owners usually want to confirm the correct 205/60R14 size, understand what that metric radial designation means, and make sure wheel condition, modifications, and general tire health are all checked before putting an 1989 Isuzu Impulse back on the road.
Tire Size & Fitment
What tire size fits a 1989 Isuzu Impulse?
The 1989 Isuzu Impulse uses a 205/60R14 tire. This is a radial size built for a 14-inch wheel, and it is the primary fitment for the model covered here, including the Base sub-model.
That means the first step is matching the car to a 205/60R14 tire rather than sorting through several original sizes. It is still smart to confirm that the wheels on the car are still 14-inch wheels and that no previous owner changed the suspension or wheel package, because those changes can affect clearance and replacement choices.
What size rim does a 1989 Isuzu Impulse use?
The 1989 Isuzu Impulse uses a 14-inch rim with its 205/60R14 tire size. In this size code, the final number, 14, identifies the wheel diameter in inches that the tire is built to mount on.
Wheel diameter is only part of the fitment picture, so it helps to check the actual wheels before buying tires. A car that has been modified over the years may have different wheels than it originally used, and wheel width or offset changes can influence how a replacement tire sits, clears suspension parts, and behaves on the road.
What does 205/60R14 mean on a 1989 Isuzu Impulse?
On a 1989 Isuzu Impulse, 205/60R14 is a metric radial tire size. The 205 is the nominal tire width in millimeters, 60 is the aspect ratio, R means radial construction, and 14 is the wheel diameter in inches.
Understanding the size helps separate the true fitment from similar-looking modern tire options. Even small changes in width, profile, or wheel diameter can affect stance, steering clearance, and overall proportions, so staying with the correct 205/60R14 size is the cleanest starting point unless the car has already been altered and the full wheel-and-tire setup is being reviewed.
Choosing the Right Tire
What should I consider when choosing a 205/60R14 tire for a 1989 Isuzu Impulse?
Start with the correct size and construction: the 1989 Isuzu Impulse uses a 205/60R14 radial tire on a 14-inch wheel. That keeps the basic fitment simple, so the real choice is selecting a tire that suits the car's present use, whether it is mostly preserved, driven regularly, or used for occasional weekend outings.
Beyond size, check the condition and dimensions of the wheels already on the car. A well-chosen replacement should match the existing wheel setup, maintain proper clearance, and suit the way the car is driven, while also taking into account tire age, suspension condition, and whether the Impulse has remained stock or has received aftermarket changes.
How do I choose between the available 205/60R14 tires for a 1989 Isuzu Impulse?
Choosing between 205/60R14 tires for a 1989 Isuzu Impulse begins with fitment discipline rather than brand loyalty. The tire needs to match the 14-inch wheel and preserve the size the car was built around, so the first filter is always correct dimensions and radial construction.
After that, compare the tires in terms of how the car will actually be used. An Impulse that sees careful collector use may lead to a different choice than one driven more often, and any selection should be checked against wheel condition, alignment, suspension wear, and the overall presentation the owner wants to keep on the car.
Why is staying with the correct 205/60R14 size important on a 1989 Isuzu Impulse?
Staying with 205/60R14 matters because that is the primary size used on the 1989 Isuzu Impulse. Using the intended size helps preserve the wheel match, overall proportions, and the baseline fitment the car was built around.
Moving away from the correct size without carefully reviewing the whole setup can create avoidable problems. A different width, profile, or wheel diameter may change clearance at the fenders or suspension and can alter the car's appearance in ways an owner may not want, especially on a model that already has a specific late-1980s sport-compact stance.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Isuzu Impulse?
For a period-style 1989 Isuzu Impulse, the strongest starting point is the correct 205/60R14 radial size. Because the car comes from a late-1980s era that already used modern metric radial sizing, keeping the proper size does more for an authentic overall look than chasing an unrelated vintage-style tire format.
Appearance decisions should still be made with the whole car in mind, including wheel design, ride height, and whether the car remains close to stock. Owners pursuing a highly exact restoration should also compare their tire choice against marque-specific references and surviving original examples, especially if presentation matters as much as road use.
Does correct tire fitment matter for a 1989 Isuzu Impulse restoration?
Correct tire fitment matters because the tire is a visible part of the car's stance and one of the first details that can make a restored 1989 Isuzu Impulse look right or look off. Using the proper 205/60R14 size helps keep the car aligned with its intended late-1980s radial fitment.
A restoration-minded owner should think beyond diameter alone and look at the entire wheel-and-tire presentation. Even when a different size can be mounted, it may change proportions in a way that distracts from the car's original character, so careful measurement and vehicle-specific historical checking are worthwhile before making a visual change.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Isuzu Impulse?
Yes, modifications can affect tire fitment on a 1989 Isuzu Impulse even when the original size is 205/60R14. Changes to wheels, suspension height, alignment settings, or body clearance can all alter how a tire sits and whether it clears through turning and suspension travel.
A stock-size tire is still the safest starting point for fitment research, but a modified car should be checked as it sits today. Wheel width, offset, spring condition, and any lowering or aftermarket components can change the available space, so measuring the actual setup is more useful than assuming every Impulse remains in factory configuration.
What should I inspect before driving a 1989 Isuzu Impulse on new tires?
Before driving a 1989 Isuzu Impulse on new tires, inspect the wheels for damage or corrosion and make sure the tire size matches the car's 205/60R14 fitment. It also helps to check valve stems, lug hardware, alignment condition, and visible suspension wear before putting the car back into regular road use.
A fresh set of tires cannot compensate for neglected chassis or wheel issues. Looking over tire pressure, steering response, brake condition, and clearance at full lock gives a better sense of whether the car is ready for normal driving, especially if it has spent long periods parked or has changed hands several times.
How often should tires on a 1989 Isuzu Impulse be inspected?
Tires on a 1989 Isuzu Impulse should be inspected regularly, especially if the car is driven infrequently or stored for long periods. A collector or hobby car can develop age-related tire problems even when tread wear looks minimal, so visual checks matter as much as mileage.
Look for cracking, bulges, cuts, uneven wear, and signs of slow air loss, and include the spare if the car still carries one. Pressure should be checked before longer drives, and storage conditions deserve attention as well, since prolonged heat, sunlight, moisture, and ozone exposure can shorten tire life on low-use enthusiast vehicles.
