The 1993 Geo Metro belongs to an era when lightweight, efficient small cars were designed around compact wheel-and-tire packages that played a big role in ride quality, fuel economy, and overall character. For many owners today, that makes tire selection less about appearance alone and more about matching the exact configuration of the car. The 1993 Geo Metro uses two primary radial tire sizes, 145/80R12 or 165/65R13, depending on the sub-model. That means the key decision is confirming whether the car is a Base, XFi, or LSi before choosing a replacement. Once that is settled, the focus shifts to maintaining the proper size, rim diameter, and everyday drivability.
Which Tire Size Is Right for The 1993 Geo Metro
The 1993 Geo Metro uses two primary tire sizes, and the correct one depends on the specific sub-model. Just as importantly, these sizes do not share the same rim diameter, so the first step is confirming whether the car is equipped for a 12-inch or 13-inch wheel before selecting a tire. Once that is verified, the decision becomes choosing the right radial tire within the correct size for the car's setup.
145/80R12 is a metric radial size in which 145 identifies the nominal section width in millimeters, 80 is the aspect ratio, R indicates radial construction, and 12 is the rim diameter in inches. On the 1993 Geo Metro, this size suits the smaller-wheel setup used on certain sub-models and preserves the compact proportions the car was designed around. Its dimensions reflect a narrow, tall-sidewall small-car radial format rather than a wider modern performance size. This is the size to evaluate when the car retains its original-style 12-inch wheel package and a stock-type overall tire profile is the goal.
165/65R13 is also a metric radial size, with 165 representing nominal section width in millimeters, 65 identifying the aspect ratio, and 13 marking the required rim diameter in inches. For the 1993 Geo Metro, this size belongs to a different wheel configuration than the 145/80R12 setup, so it should be chosen only after confirming the car's wheel diameter and sub-model. The lower aspect ratio and wider section create a distinct sizing profile within the Metro range. This size is the correct starting point for an LSi-equipped car or any Metro that still uses the matching 13-inch wheel arrangement.
Sub-model fitment matters on the 1993 Geo Metro because the covered versions do not all use the same tire size or wheel diameter. Identifying whether the car is a Base, LSi, or XFi is the simplest way to narrow the correct tire before comparing replacement options.

1993 Geo Metro Base
The 1993 Geo Metro Base uses the 145/80R12 radial size, placing it in the 12-inch wheel configuration. Tire selection for this sub-model starts with preserving that wheel diameter and matching the narrow metric radial format the car was built to use.
The 1993 Geo Metro LSi uses the 165/65R13 radial size, which differs from the other Metro sub-models covered here. That makes wheel confirmation especially important, since choosing for an LSi means staying with the 13-inch setup rather than assuming all 1993 Metro tires are the same.
The 1993 Geo Metro XFi uses the 145/80R12 radial size, matching the 12-inch wheel package rather than the LSi arrangement. For tire selection, that means focusing on the correct narrow radial size and avoiding substitutions based only on the broader Metro model name.
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
Tire questions for a 1993 Geo Metro usually come down to sub-model fitment, 12-inch versus 13-inch wheels, and understanding what each metric radial size means. The FAQs below also cover selection, maintenance, and the checks that matter before putting a low-weight older compact car back on the road.
Tire Size & Fitment
What tire size fits a 1993 Geo Metro?
A 1993 Geo Metro uses either 145/80R12 or 165/65R13, and both are radial sizes. The Base and XFi use 145/80R12, while the LSi uses 165/65R13. That means there is not one universal tire size for every 1993 Metro.
The practical step is to confirm the car's exact sub-model and wheel diameter before choosing a tire. Since these two sizes mount on different rims, selecting by model year alone can lead to the wrong tire. A quick check of the existing tire sidewall and wheel size helps confirm which Metro setup the car actually has.
What size rim does a 1993 Geo Metro use?
A 1993 Geo Metro uses either a 12-inch or 13-inch rim, depending on the sub-model. The 145/80R12 tire fits a 12-inch rim, while the 165/65R13 tire fits a 13-inch rim. Rim diameter is part of the tire size itself, so it cannot be mixed between these two fitments.
Wheel diameter should be checked before any other tire decision, especially on an older compact car that may have had wheels changed over time. A Metro wearing replacement wheels may no longer match its original sub-model pattern. Confirming the actual wheel on the car prevents ordering a tire that is correct for the model name but wrong for the rim.
Do all 1993 Geo Metro sub-models use the same tire size?
No, the 1993 Geo Metro sub-models covered here do not all use the same tire size. The Base and XFi use 145/80R12, while the LSi uses 165/65R13. Both are radial tires, but they belong to different wheel diameters and different fitment setups.
That difference matters because a Metro owner needs to identify the exact sub-model or at least confirm the wheel size before replacing tires. It is also wise to inspect what is currently installed, since some older cars have been changed from stock wheel packages over the years. Matching the tire to the actual wheel is more important than assuming all Metro trims used one size.
Choosing the Right Tire
What should I consider when choosing a tire for a 1993 Geo Metro?
Start with the correct size for the specific car: 145/80R12 for the Base and XFi, or 165/65R13 for the LSi. The 1993 Geo Metro uses radial construction, so the main selection issue is not bias-ply versus radial, but choosing the proper size and wheel diameter combination for the car's actual setup.
After size is confirmed, look at how the Metro is used. A lightly driven original car may simply need a proper stock-type replacement size, while a driver-quality car also benefits from checking overall tire condition, age, and uniformity across all four corners. Staying with the correct metric size helps preserve steering response, clearance, and the small-car balance the Metro was designed around.
How do I choose between the available 1993 Geo Metro tire sizes?
The two tire sizes for a 1993 Geo Metro are not interchangeable choices for the same car. They are tied to different sub-models and different rim diameters. A Base or XFi calls for 145/80R12, while an LSi uses 165/65R13, so the deciding factor is vehicle configuration rather than personal preference.
Once the correct size is established, compare the tire on the car with the wheel diameter and verify that all four wheels match. On older economy cars, wheel swaps are common enough that a trim badge alone should not be the only reference point. Choosing by confirmed size helps avoid rubbing issues, mounting problems, and a mismatched stance from one axle to the other.
Why does choosing the correct wheel diameter matter on a 1993 Geo Metro?
Wheel diameter matters on a 1993 Geo Metro because its two primary tire sizes are built for different rims. The 145/80R12 requires a 12-inch rim, and the 165/65R13 requires a 13-inch rim. Even though both sizes are close in overall proportions, the bead seat diameter is different and must match the wheel exactly.
That makes wheel confirmation essential before mounting any replacement tire. A Metro that has changed hands several times may have replacement wheels, mixed spare-wheel setups, or trim changes that blur the original sub-model pattern. Checking the wheel first keeps the tire search focused and prevents chasing a size that sounds right for the car but cannot be mounted safely.
Restoration & Appearance
Which tire should I choose for a period-style 1993 Geo Metro?
A period-style approach starts with the tire size that matches the car's original-type wheel package for its sub-model. On a 1993 Geo Metro, that means 145/80R12 for the Base and XFi or 165/65R13 for the LSi. Because the Metro is a modern-era compact, proper size and stance matter more than decorative sidewall treatments.
Keeping the correct wheel diameter and metric radial sizing helps the car look proportionate and true to its early-1990s character. Owners pursuing a more exact restoration should also compare the current wheel and tire setup with marque references, original photos, or other vehicle-specific material. That step is especially useful if the car has had wheels replaced during its life.
Does correct tire fitment matter for a 1993 Geo Metro restoration?
Yes, correct tire fitment matters on a 1993 Geo Metro restoration because the car's small dimensions make tire proportion especially noticeable. Using 145/80R12 or 165/65R13 as appropriate to the sub-model keeps the wheel-and-tire package in the range the car was designed to use, both visually and functionally.
An incorrect size can change the car's stance, wheel-well appearance, and overall presentation even before driving impressions enter the picture. It can also complicate clearance and steering feel if the wheel package has been altered. For a restoration-minded owner, matching the tire to the right sub-model and rim diameter is one of the simplest ways to keep the finished car coherent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 Geo Metro?
Yes, modifications can affect tire fitment on a 1993 Geo Metro. Aftermarket wheels, suspension changes, lowering, or body alterations can change the space available for either 145/80R12 or 165/65R13. Even when the tire size sounds close to stock, the actual wheel diameter and surrounding clearance still need to be checked.
That is especially important on a small, lightweight car where minor changes are more noticeable. A Metro with replacement wheels may have different width or offset than the factory-style setup, which can influence steering clearance and fender room. Verifying the current wheel and suspension arrangement before mounting tires helps avoid surprises once the car is back on the road.
What should I inspect before driving a 1993 Geo Metro on new tires?
Before driving a 1993 Geo Metro on new tires, inspect the wheels for damage, confirm that the tire size matches the rim diameter, and make sure the tires are mounted consistently across the axle. It is also wise to check valve stems, inflation pressure, and general wheel condition, especially on a car that may have spent long periods parked.
A road-ready inspection should also include suspension and steering basics such as loose components, uneven ride height, and any signs of rubbing with the wheels turned. Older economy cars can hide wear because they are so light and simple. Catching those issues early helps the new tires wear properly and keeps the car predictable in everyday driving.
How should tires on a collector-era 1993 Geo Metro be maintained?
Tires on a collector-era 1993 Geo Metro should be checked regularly for air pressure, tread wear, cracking, bulges, cuts, and signs of age-related hardening. Because many surviving Metros are driven infrequently, time and storage conditions can matter as much as mileage. The correct size should also be maintained consistently on the proper wheel diameter.
Storage habits make a difference on low-use cars. Keeping the Metro away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition over time. Occasional visual checks are useful, but a more careful inspection before any longer drive is the smarter habit. That approach helps catch slow leaks or age issues before they become roadside problems.
