The 1991 Isuzu Stylus came to market during a period when compact imports were leaning harder into sharper styling and more responsive road manners. Its low-slung profile and tidy proportions gave it a distinctly modern early-1990s character, and tire fitment plays a direct role in preserving that feel today. This model uses radial tires, but fitment is split between 175/70R13 and 185/60R14 depending on the sub-model. That means the tire decision centers on confirming whether the car is an S or an XS, then choosing among the available blackwall radial options in the correct rim diameter. For an unrestored car or a modified survivor, wheel size should be checked before selecting tires.
Which Tire Size Is Right for The 1991 Isuzu Stylus
The 1991 Isuzu Stylus uses two primary tire sizes, and the right one depends on the specific sub-model. The Stylus S uses a 13-inch radial fitment, while the Stylus XS steps up to a 14-inch radial fitment, so confirming the sub-model and actual wheel diameter should come first. Once that is settled, the choice becomes a matter of selecting the right radial tire within the proper size and rim-width range.
175/70R13 is a metric radial size in which 175 indicates the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 13 is the wheel diameter in inches. On the 1991 Isuzu Stylus, this size is used on the S sub-model and keeps the fitment tied to a 13-inch wheel. Available choices in this size include an Avon blackwall tire from the CR6ZZ series. This is the size to evaluate when the car retains its original 13-inch wheel setup or another wheel package with the same diameter and compatible width.
185/60R14 is a metric radial size with a 185-millimeter nominal section width, a 60-series profile, radial construction, and a 14-inch rim diameter. For the 1991 Isuzu Stylus, this size applies to the XS sub-model and reflects a different wheel diameter than the S. In this fitment, the available product is a Michelin blackwall tire from the Michelin Pilot Exalto PE2 series. This size should be considered when the car is an XS or when the vehicle clearly carries a 14-inch wheel package that matches the intended fitment.
Sub-model identification matters on the 1991 Isuzu Stylus because tire fitment changes between the covered versions. The S and XS do not share the same wheel diameter, so confirming the exact sub-model is the first step before comparing tires.

1991 Isuzu Stylus S
The 1991 Isuzu Stylus S uses a 175/70R13 radial fitment on a 13-inch wheel. That keeps tire selection focused on the correct metric radial size and on verifying that the car has not been changed to a different wheel diameter over the years.
The 1991 Isuzu Stylus XS uses a 185/60R14 radial fitment on a 14-inch wheel. Tire selection here starts with the proper 14-inch size, then moves to comparing product character, rim-width compatibility, and the overall condition of the wheel and suspension setup.
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.

Tire Size & Fitment
What tire size fits a 1991 Isuzu Stylus?
A 1991 Isuzu Stylus uses one of two radial tire sizes depending on sub-model. The Stylus S uses 175/70R13, while the Stylus XS uses 185/60R14. Those sizes are tied to different wheel diameters, so they should not be treated as interchangeable just because they belong to the same model line.
The practical first step is confirming whether the car is an S or an XS, then checking the actual wheel diameter on the vehicle. Older compact cars are often fitted with replacement wheels over time, and that can change what size tire belongs on the car now. Tire selection should follow the sub-model and wheel that are actually present.
What size rim does a 1991 Isuzu Stylus use?
The 1991 Isuzu Stylus uses either a 13-inch or 14-inch rim, depending on sub-model. The S uses a 13-inch wheel with 175/70R13 tires, and the XS uses a 14-inch wheel with 185/60R14 tires. Both are radial fitments, but the wheel diameter changes with the tire size.
Checking rim diameter before ordering tires is especially important on a car from this era. The size molded into the old tire can help, but the wheel itself should still be verified in case the car has been changed at some point. Rim width matters too, so the wheel should match the tire's approved width range as well as its diameter.
Why does the 1991 Isuzu Stylus have more than one tire size?
The 1991 Isuzu Stylus has more than one tire size because the fitment changes by sub-model. The Stylus S uses 175/70R13, while the Stylus XS uses 185/60R14. That means the difference is not random variation within one setup, but a distinction tied to the version of the car.
That split matters because the two sizes use different rim diameters and should be approached as separate fitments. A buyer should identify the exact sub-model, inspect the wheel size currently on the car, and make sure any prior wheel or suspension changes have not altered the tire requirements. Starting with the wrong wheel diameter creates the biggest fitment mistake here.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Isuzu Stylus?
Start with the correct sub-model size, because the 1991 Isuzu Stylus does not use one universal fitment. The S requires 175/70R13 and the XS requires 185/60R14, both in radial construction. After size, the next priorities are wheel diameter, approved rim-width range, and whether the tire suits the car's intended street use.
Once fitment is confirmed, compare the available product characteristics rather than chasing a different size. Blackwall styling is consistent across the current options, but the tires come from different brands and series, so the buyer should focus on the combination of correct dimensions, wheel compatibility, and the type of driving the car actually sees.
What sidewall styles are available for 1991 Isuzu Stylus tires?
The available 1991 Isuzu Stylus tire options in these sizes use a blackwall sidewall style. That applies to both the 175/70R13 and 185/60R14 fitments, giving the car a clean, understated appearance that suits a compact import from the early 1990s without introducing a more vintage sidewall treatment.
Since sidewall appearance is straightforward here, the more important selection points are the correct size for the sub-model and the wheel dimensions on the car. A blackwall tire can still vary in overall character by brand and series, so the decision should center on fitment first and then on how closely the tire matches the intended use of the Stylus.
What brands offer tires for the 1991 Isuzu Stylus?
The available tires for the 1991 Isuzu Stylus come from Avon and Michelin. Avon covers the 175/70R13 fitment with the CR6ZZ series, while Michelin covers the 185/60R14 fitment with the Michelin Pilot Exalto PE2 series. Brand choice is therefore tied directly to the size used by the specific sub-model.
That means the buying decision is not simply picking between two brands in one shared size. Instead, the owner should confirm whether the car uses the S or XS fitment, then compare the characteristics of the tire offered in that exact size. Wheel width and the car's present setup still deserve a quick check before settling on the final choice.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Isuzu Stylus?
A period-style 1991 Isuzu Stylus should begin with the correct original fitment type for the specific sub-model: 175/70R13 radial for the S or 185/60R14 radial for the XS. Since both available options are blackwall radials, the visual presentation stays in step with the clean, modern compact-car look associated with the era.
For an appearance-minded selection, keeping the proper wheel diameter and tire profile for the sub-model usually matters more than chasing cosmetic details. A car that has been changed to aftermarket wheels can lose some of its original visual balance, so wheel size and stance should be checked before choosing a replacement tire for restoration-oriented use.
Does correct tire fitment matter for a 1991 Isuzu Stylus restoration?
Correct tire fitment matters on a 1991 Isuzu Stylus restoration because the car uses two distinct radial sizes tied to different sub-models and wheel diameters. Using the proper 175/70R13 or 185/60R14 fitment helps preserve the proportions, wheel-to-tire relationship, and overall visual character that suit the car's original design.
It also affects how the finished restoration sits and functions on the road. A buyer working toward a highly accurate result should verify the exact sub-model and wheel setup before purchasing tires, then compare the tire's dimensions and approved wheel range carefully. That approach avoids solving a cosmetic problem by creating a fitment problem somewhere else.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Isuzu Stylus?
Yes, modifications can affect tire fitment on a 1991 Isuzu Stylus. Wheel changes, lowering, altered springs, and suspension work can all change the space available around a 175/70R13 or 185/60R14 tire. Even when the tire size remains close to stock, wheel width and offset can alter how the tire sits in the fender opening.
A modified car should be checked at the wheel and on the vehicle before a tire is chosen. Steering clearance, inner-fender clearance, and the actual wheel dimensions matter more once the setup has changed from original. That is especially important here because the Stylus already has two legitimate factory fitments, so assumptions based on model name alone can be misleading.
What should I inspect before driving a 1991 Isuzu Stylus on new tires?
Before driving a 1991 Isuzu Stylus on new tires, inspect the wheels for correct diameter and condition, confirm the tires are mounted in the right size for the sub-model, and check inflation, valve stems, and basic clearance. The suspension and steering components should also be looked over so the new tires are not asked to work around worn hardware.
A quick road-use inspection should also include looking for rubbing marks, uneven old tire wear, and any signs of alignment issues. On an older compact car, those clues can reveal problems that a fresh tire alone will not fix. Catching them early helps protect the new tires and makes the car more predictable once it returns to regular driving.
How often should tires on a 1991 Isuzu Stylus be inspected?
Tires on a 1991 Isuzu Stylus should be inspected regularly, not just when tread looks low. A visual check for cracking, bulges, cuts, irregular wear, and air loss is worthwhile before longer drives and at routine intervals in normal use. That matters even more on an older car that may spend long periods parked between outings.
Collector and low-mileage habits can hide tire problems because age and storage conditions affect tires even when the car is driven sparingly. Checking pressure, sidewall condition, and tread wear pattern on a repeating schedule helps catch trouble early. It is also a good time to confirm that the car is still wearing the correct S or XS fitment.
