The 1988 Isuzu Impulse came from an era when imported sport coupes balanced sharp styling, compact dimensions, and everyday usability in a way that still appeals to collectors today. Its Giugiaro-influenced shape and late-1980s character make tire selection more than a maintenance decision, because the wrong size can quickly change both stance and road manners. For this model, the primary fitment is a 205/60R14 radial on a 14-inch rim. That keeps the decision centered on choosing the right radial tire in the correct metric size rather than sorting through multiple factory fitments. For restoration-minded owners and drivers alike, wheel condition, tire age, and actual vehicle setup are worth checking before putting the car back into regular road use.
Which Tire Size Is Right for The 1988 Isuzu Impulse
The 1988 Isuzu Impulse uses one primary tire size: 205/60R14, and it is a radial fitment on a 14-inch rim. The 1988 Isuzu Impulse Base uses that same size, so the main decision is not which factory size applies, but selecting the right tire within that size and confirming that the car still has its original wheel and suspension setup.
205/60R14 is a metric radial size in which 205 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 14 is the wheel diameter in inches. On the 1988 Isuzu Impulse, that sizing reflects a lower-profile late-1980s fitment rather than an older bias-ply or tall-sidewall format. The practical focus here is maintaining the correct size relationship for the car’s handling balance, appearance, and wheel compatibility. It is a strong starting point for owners who want to preserve the Impulse’s intended stance while verifying wheel condition, tire age, and clearance on any modified car.
Sub-model fitment is straightforward for the 1988 Isuzu Impulse covered here. The Base model uses the same primary tire size, which means tire selection stays focused on choosing the right 205/60R14 radial and confirming that the car still wears the correct 14-inch wheels.

Frequently Asked Questions
These FAQs for the 1988 Isuzu Impulse focus on the original 205/60R14 radial fitment, 14-inch wheel compatibility, tire-selection priorities, restoration-minded considerations, and the inspections worth making before road use.
Tire Size & Fitment
What tire size fits a 1988 Isuzu Impulse?
The 1988 Isuzu Impulse uses a 205/60R14 radial tire. That size combines a 205-millimeter nominal section width, a 60-series aspect ratio, and a 14-inch rim diameter, which places it squarely in the modern metric radial format common on late-1980s sport coupes.
Using the correct size matters because a different diameter or profile can change the car’s stance, clearance, and overall driving feel. Before replacing tires, confirm that the Impulse still has 14-inch wheels and has not been altered with aftermarket wheels, suspension changes, or body modifications that could affect what actually works on the car today.
What size rim does a 1988 Isuzu Impulse use?
The 1988 Isuzu Impulse uses a 14-inch rim with its 205/60R14 tire size. In that size code, the final number identifies wheel diameter, so the tire is built for a 14-inch wheel rather than a 13-inch, 15-inch, or other rim size.
Rim diameter should be confirmed before ordering replacement tires, especially on a car that may have changed hands several times. Checking the actual wheel on the vehicle helps avoid confusion if the car has aftermarket wheels installed, and it also gives a good opportunity to inspect wheel condition, bead-seat area, and any signs of prior curb damage or corrosion.
Does the 1988 Isuzu Impulse Base use the same tire size?
Yes. The 1988 Isuzu Impulse Base uses the same 205/60R14 radial tire size. That makes fitment straightforward within the covered sub-model range, since the main factory fitment question is already settled without having to sort between multiple original tire sizes.
Even with shared fitment, the actual car should still be checked before replacement. A Base model may now wear different wheels than it originally did, and suspension wear or modifications can affect clearance and appearance. Matching the correct size is the starting point, but wheel diameter, wheel width, and overall condition still deserve a careful look.
Choosing the Right Tire
What should I consider when choosing a 205/60R14 tire for a 1988 Isuzu Impulse?
Start with the correct size and construction: 205/60R14 radial on a 14-inch rim. For a 1988 Isuzu Impulse, the key goal is preserving the intended relationship between tire height, section width, and wheel diameter so the car keeps the balanced look and road behavior associated with this fitment.
From there, the real considerations are the car’s present setup and intended use. A mostly original driver may benefit from staying very close to stock dimensions, while a modified car needs a closer check of wheel width, offset, and clearance. Tire age, wheel condition, and how the Impulse will actually be driven should guide the final choice.
How do I choose between available 205/60R14 tires for a 1988 Isuzu Impulse?
Choosing among 205/60R14 tires for a 1988 Isuzu Impulse comes down to selecting the correct size first, then comparing construction details and how well each tire suits the car’s role. A regularly driven coupe, a preservation-oriented car, and a lightly used collector example may not place the same priorities on replacement tires.
Focus on whether the tire maintains the proper fitment relationship for the original 14-inch wheel and whether the rest of the car supports that setup. It also helps to inspect suspension condition and alignment before installation, since worn components can make a new tire feel less stable and can shorten tread life noticeably.
What does 205/60R14 mean on a 1988 Isuzu Impulse?
On a 1988 Isuzu Impulse, 205/60R14 describes a metric radial tire size. The 205 is the nominal section width in millimeters, 60 is the aspect ratio, R means radial construction, and 14 identifies the wheel diameter in inches. It is a compact, lower-profile format typical of many sporty cars from the late 1980s.
Understanding the code helps prevent ordering a tire that is close in name but wrong in fitment. A different aspect ratio or rim diameter can alter the car’s stance and create clearance issues. Reading the wheel and tire together is the safest approach, especially if the Impulse has seen previous owner changes over the years.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Isuzu Impulse?
For a period-style 1988 Isuzu Impulse, the right starting point is the original-size 205/60R14 radial on a 14-inch rim. Keeping the stock size does more to preserve the car’s late-1980s visual character than jumping to a taller, wider, or larger-diameter substitute that changes its stance.
That does not mean every tire in the size will create the same impression, so appearance-minded owners should compare overall profile and how the tire sits on the wheel. If exact restoration accuracy matters, it is wise to check period photos, marque resources, and surviving original examples before settling on a final presentation.
Does correct tire fitment matter for a 1988 Isuzu Impulse restoration?
Yes, correct tire fitment matters on a 1988 Isuzu Impulse restoration because tire size has a visible effect on ride height, wheel opening fill, and the car’s overall proportions. Staying with 205/60R14 preserves the original-style relationship between the tire and the 14-inch wheel that defines the car’s factory-era look.
Fitment also affects more than appearance. An incorrect size can influence steering response, clearance, and the way the car sits after restoration work is complete. Even on a cosmetic project, checking wheel condition, suspension health, and alignment before installation helps the finished car look right and drive in a composed, predictable way.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Isuzu Impulse?
Yes, modifications can affect tire fitment on a 1988 Isuzu Impulse even when the original tire size is 205/60R14. Aftermarket wheels, different offsets, altered ride height, suspension changes, or bodywork can all change how much room the tire has at the fender, inner wheelhouse, and steering components.
That is why the actual car should be inspected before choosing replacement tires. A modified Impulse may still use a 14-inch wheel, but wheel width and offset can change how the tire sits. Turning the steering from lock to lock and checking full suspension travel can reveal clearance issues before they become a problem on the road.
What should I inspect before driving a 1988 Isuzu Impulse on new tires?
Before driving a 1988 Isuzu Impulse on new tires, inspect the wheels for damage or corrosion, confirm proper tire pressure, and make sure the tires are seated correctly on the rims. It also helps to look over the valve stems, lug hardware, and tread-to-body clearance at both straight-ahead and turned steering positions.
The rest of the chassis deserves attention too, especially on an older sport coupe. Worn shocks, tired bushings, loose steering parts, or poor alignment can spoil the benefit of a fresh set of tires. A short test drive followed by a recheck for rub marks, vibration, or air loss is a smart final step.
How should 205/60R14 tires on a collector 1988 Isuzu Impulse be maintained?
205/60R14 tires on a collector 1988 Isuzu Impulse should be maintained with regular pressure checks, routine visual inspection, and periodic driving or careful storage habits. Even when tread wear is low, age can become the larger concern on a lightly used collector car, especially if the vehicle spends long periods parked.
Look for cracking, flat spotting, cuts, bulges, and any slow air loss, and keep the car stored away from prolonged sunlight, excess heat, and ozone sources when possible. It also helps to inspect the tires before and after longer drives, since collector vehicles often reveal age-related issues only after returning to regular road use.
