In 1993, Geo represented General Motors’ small-car strategy with a practical, import-flavored lineup that ranged from the economy-minded Metro to the compact Prizm and the sportier Storm. That variety matters when choosing tires, because 1993 Geo models do not share one universal fitment across the range. Instead, the year spans six radial sizes across three distinct models, with each model using its own pair of sizes and rim diameters. The first thing to confirm on a 1993 Geo is the exact model, then the tire size already on the car or the wheel diameter you intend to keep, since that determines which fitment path applies.
Which Tire Size Is Right for Your 1993 Geo
Six tire sizes are used across 1993 Geo vehicles, and they vary by model rather than carrying across the full lineup. Because these sizes span 12-, 13-, 14-, and 15-inch rims, the real decision starts with confirming your exact model and wheel diameter before comparing tire choices. Understanding that distinction first saves time and helps match the right tire to the right Geo.
Year(s): 1993|Fit(s): Metro|Construction: Radial|Rim: 12-in rim
145/80R12 is a metric radial size with a 145-millimeter section width, an 80-series aspect ratio, and a 12-inch rim diameter. This size is specific to the 1993 Geo Metro, and no product range is present here to compare brands, sidewall styles, or tube details. It suits buyers restoring or maintaining a Metro on its smaller original wheel format. Confirm the wheel diameter on the car before moving forward, since this size is not shared with other 1993 Geo models.
Year(s): 1993|Fit(s): Metro|Construction: Radial|Rim: 13-in rim
165/65R13 is a metric radial size with a 165-millimeter section width, a 65-series aspect ratio, and a 13-inch rim diameter. This size is also specific to the 1993 Geo Metro, with no brand, sidewall style, or tube-status variation available here to compare. It fits Metro applications running the larger of that model’s two wheel and tire combinations. Check whether your Metro is on 12-inch or 13-inch wheels before choosing between its two sizes.
Year(s): 1993|Fit(s): Prizm|Construction: Radial|Rim: 14-in rim
175/65R14 is a metric radial size with a 175-millimeter section width, a 65-series aspect ratio, and a 14-inch rim diameter. This size is specific to the 1993 Geo Prizm, and no current comparison of brands, sidewall styles, or speed-marked product variation appears here. It is the narrower of the two Prizm fitments and keeps the choice centered on the correct model and wheel diameter. Verify the existing tire size on the car if your Prizm could have either 14-inch option.
Year(s): 1993|Fit(s): Prizm|Construction: Radial|Rim: 14-in rim
185/65R14 is a metric radial size with a 185-millimeter section width, a 65-series aspect ratio, and a 14-inch rim diameter. This Prizm-specific size shares the same rim diameter as the other Prizm fitment, though no brand or sidewall range is present here for a product-by-product comparison. It is the wider of the two 14-inch Prizm sizes and should be chosen only if it matches the wheel and application on the car. Confirm the exact size already fitted before replacing a full set.
Year(s): 1993|Fit(s): Storm|Construction: Radial|Rim: 14 in
185/60R14 is a metric radial size with a 185-millimeter section width, a 60-series aspect ratio, and a 14-inch rim diameter. For the 1993 Geo Storm, this size is available as a Michelin blackwall radial in the Pilot Exalto PE2 series, with tubeless construction and an 82V speed rating for a 149 mph ceiling. It is the 14-inch Storm fitment and makes sense for buyers keeping the car on its correct wheel diameter while using a modern radial performance-oriented tire. Michelin fits this size on 5- to 6-inch rims, so wheel width should be confirmed before ordering.
Year(s): 1993|Fit(s): Storm|Construction: Radial|Rim: 15-in rim
205/50R15 is a metric radial size with a 205-millimeter section width, a 50-series aspect ratio, and a 15-inch rim diameter. This size is specific to the 1993 Geo Storm, and no product range appears here to compare brands, sidewall styles, or speed-rating variation. It serves the larger-wheel Storm setup and should be chosen only for cars already using the 15-inch fitment. Checking the wheel diameter first is especially important because the Storm used both 14-inch and 15-inch sizes.
Three 1993 Geo models are covered here: Metro, Prizm, and Storm. Tire size changes by model, so identifying the exact vehicle matters before narrowing the search to a specific fitment. Select a model below to see model-specific tire history, size guidance, and available products.
1993 Geo Metro
The 1993 Geo Metro was the lineup’s economy specialist, known for light weight, simple packaging, and city-friendly proportions. Metro models here use either 12-inch or 13-inch wheel fitments, so the key step is confirming which wheel package your car carries before selecting tires.
The 1993 Geo Prizm filled the compact sedan role in the Geo range, with a more mainstream, everyday character than the Metro and a different mission than the Storm. Prizm fitments here stay on 14-inch wheels, but the model uses two distinct sizes, so matching the exact tire size on the car remains important.
The 1993 Geo Storm was the sport-leaning car in the Geo family, and its tire fitments reflect that more athletic intent. Storm applications here run either a 14-inch or 15-inch wheel, making wheel diameter the first checkpoint before choosing between its two sizes.
One product is available across six tire sizes for 1993 Geo vehicles. The 185/60R14 Storm fitment includes one Michelin radial in blackwall form, so confirm your exact size and wheel diameter before selecting a tire.
These FAQs focus on how 1993 Geo tire sizes change from Metro to Prizm to Storm, what the metric radial size codes mean, and what to check before fitting or storing a low-use 1990s compact.
Size Basics & Fitment
What tire sizes fit 1993 Geo vehicles?
1993 Geo vehicles use six sizes across three models. The Metro uses 145/80R12 and 165/65R13, the Prizm uses 175/65R14 and 185/65R14, and the Storm uses 185/60R14 and 205/50R15. Those sizes do not interchange across the full 1993 Geo range, and the rim diameters span 12, 13, 14, and 15 inches depending on model.
That means year and make alone are not enough to choose tires for a 1993 Geo. Start by identifying whether you have a Metro, Prizm, or Storm, then confirm the wheel diameter and the size already fitted to the car. On the Storm, one available 185/60R14 tire fits 5- to 6-inch rims, which is a reminder to verify wheel width whenever product details are available.
What does 145/80R12 mean on a 1993 Geo tire?
On a 1993 Geo, 145/80R12 is a metric radial size. The 145 is the section width in millimeters, 80 is the aspect ratio, the R means radial construction, and 12 is the wheel diameter in inches. This size belongs to the Metro rather than the full Geo lineup.
That code tells you more than just diameter. It identifies a narrow, small-wheel fitment that suits the Metro’s compact packaging, and it should not be confused with the Metro’s alternate 165/65R13 option. If your 1993 Geo is wearing 12-inch wheels, this is the kind of size format you should expect to see on the sidewall.
Do all 1993 Geo models use the same tire size?
No, 1993 Geo models do not use the same tire size. The Metro, Prizm, and Storm each have their own pair of radial sizes, and none of those sizes is shared across all three models. Even within one model line, there can be two factory-style size paths tied to different wheel diameters or equipment levels.
That makes model identification essential before replacing tires on a 1993 Geo. If you are unsure, check the existing sidewall marking and measure the wheel diameter rather than choosing by appearance alone. The Storm is a good example: one fitment uses a 14-inch wheel and the other uses a 15-inch wheel, so guessing can send you in the wrong direction quickly.
Buying the Right Tire
What sidewall styles are available for 1993 Geo tires?
For 1993 Geo applications covered here, the visible sidewall style currently present is blackwall on the 185/60R14 size used by the Geo Storm. That fits the practical, late-1980s-to-1990s character of many small import-based compact cars, where blackwall and understated styling were common rather than wide whitewall or heavily styled vintage sidewalls.
Sidewall appearance still matters because it affects how finished the car looks, especially on a clean original or lightly restored driver. If your 1993 Geo is a Storm and you want a straightforward period-appropriate look, a blackwall radial aligns naturally with the car’s era. For Metro and Prizm sizes, the best approach is to choose the correct fitment first, then compare sidewall appearance within that size category.
What brands make tires for 1993 Geo vehicles?
Michelin currently covers one 1993 Geo fitment here, the 185/60R14 used on the Geo Storm, through the Pilot Exalto PE2 series. No brand spread is present across the other 1993 Geo sizes in this selection, so the visible branded option centers on the Storm’s 14-inch application rather than the full year-and-make range.
Brand choice matters most after you have confirmed the exact model and size. A Metro buyer and a Storm buyer are not shopping the same dimensions, so the first filter should always be fitment rather than badge preference. Once the correct size is established, compare the tire’s intended character, sidewall appearance, and construction details to the way you use your 1993 Geo.
What is the difference between Michelin Pilot Exalto PE2 and other 1993 Geo tire options?
Within the 1993 Geo range shown here, Michelin Pilot Exalto PE2 appears on the 185/60R14 Storm fitment as a radial blackwall tire with an 82V speed rating, tubeless construction, a 14-pound weight, and a 5- to 6-inch rim width range. The other 1993 Geo sizes shown here do not carry a parallel product spread to compare line by line in the same way.
That makes the Michelin option less a broad year-and-make comparison and more a focused choice for the 14-inch Storm application. If your car is a Metro or Prizm, the question is not whether this Michelin is preferable, but whether your car even uses that size. Fitment first, then tire character, is the right order for sorting out a 1993 Geo.
Fitting & Setup
What rim width do 1993 Geo tires require?
A confirmed rim width range appears here for one 1993 Geo fitment: the 185/60R14 used on the Geo Storm fits 5- to 6-inch rims. The other sizes do not carry a visible rim-width range in this selection, so the safest course is to match the tire to the wheel already on the car rather than assuming the same width rule carries across Metro, Prizm, and Storm applications.
Rim width matters because it affects how the tire seats, how the tread sits on the road, and whether the overall fit looks and behaves as intended. If you are working with a Storm on 14-inch wheels, confirm that the wheel falls inside the 5- to 6-inch range. On other 1993 Geo models, compare the wheel and existing tire size carefully before changing dimensions.
Do 1993 Geo tires require inner tubes?
The 185/60R14 tire option for the 1993 Geo Storm is tubeless, marked TL. No conflicting tube-type marking appears within that fitment here, and no tube-status variation is present for that size. The other 1993 Geo sizes do not show a competing tube requirement in this selection, which is consistent with the tubeless radial character expected on a 1993 compact-car application.
Even so, a tubeless tire still depends on the condition of the wheel, valve stem, and bead seat. If your 1993 Geo has older wheels, corrosion or damage at the sealing surfaces can create slow leaks that have nothing to do with the tire itself. Treat valve stems and wheel condition as part of the installation, especially on a car that has spent long periods parked.
Maintenance, Storage & Longevity
How should I store a 1993 Geo when the tires are fitted?
A 1993 Geo stores best in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that accelerate rubber aging. Keep the tires properly inflated, avoid parking on damp soil, and move the car periodically if possible so the same tread area is not loaded in one spot for months at a time.
Collector compacts often sit longer than daily drivers, and that makes storage habits matter more than mileage. If the car will be parked for an extended stretch, clean the tires, place the vehicle on a smooth surface, and consider reducing static load with periodic repositioning or proper stands. Good storage preserves sidewalls, helps prevent flat spotting, and makes the next drive-inspiring rather than worrisome.
How long do tires on a 1993 Geo typically last?
On a 1993 Geo, tire age is usually a better guide than tread depth because many surviving examples are lightly driven. A practical rule is to begin evaluating condition closely once tires reach about five to seven years of age and to consider replacement around the ten-year mark regardless of remaining tread. The DOT date code on the sidewall helps establish that timeline.
Low annual mileage can make old tires look healthier than they really are. Rubber hardens over time, internal materials age, and a compact car that feels light and easy to drive can still suffer from reduced grip or sidewall integrity if the tires are old. If the age is approaching that outer window, inspect carefully and replace on condition rather than waiting for visible failure.
How often should tires on a 1993 Geo be inspected?
Tires on a 1993 Geo should be checked before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, punctures, and low pressure, and make sure the spare is usable as well. On a tubeless fitment such as the 185/60R14 Storm application, valve stem condition and bead sealing are part of that inspection.
Frequent checks matter because small, older cars transmit changes in tire condition quickly through ride and handling. A tire that loses pressure slowly in storage can still appear serviceable at a glance, so using a gauge is more reliable than visual judgment alone. Build tire inspection into your regular pre-drive routine, especially if your 1993 Geo is not driven every week.
Safety & Road Use
Are 1993 Geo tires safe for highway driving?
1993 Geo tires can be suitable for highway driving when the correct size is fitted, the tire is in sound condition, and the product’s speed rating matches the way the car is used. One confirmed example is the 185/60R14 Michelin for the Geo Storm, which carries a V rating with a 149 mph ceiling. That rating far exceeds normal U.S. highway speeds, though the car’s own mechanical condition remains the more important real-world limit.
Safety on the road comes from the complete package rather than the sidewall code alone. Alignment, suspension wear, brakes, wheel condition, and tire age all matter on a 1993 Geo, especially because these are now older vehicles. If the car has been stored, bring it back into use methodically and treat speed rating as only one part of a broader roadworthiness check.
What inflation pressure should I use for 1993 Geo tires?
Inflation pressure for a 1993 Geo should follow the vehicle manufacturer’s recommendation for the exact model and size, with the tire maker’s maximum pressure figure understood as the tire’s rated limit rather than the everyday setting. One visible 1993 Geo product here, the 185/60R14 Michelin for the Storm, carries its own load and pressure standard within that tire’s specification, but that figure should not be transferred to Metro or Prizm sizes.
Pressure choice affects wear, ride quality, and stability, so using the wrong number can create problems even when the tire size is correct. Check the owner’s manual, door-jamb decal if present, and the tire’s own sidewall information together. Whenever a 1993 Geo has moved away from its original wheel-and-tire setup, use extra care to confirm the appropriate pressure for that exact combination.
What should I check before taking a 1993 Geo on a longer drive?
Before a longer drive in a 1993 Geo, inspect each tire for cracks, cuts, punctures, bulges, uneven wear, and proper inflation, and examine the valve stems and spare as well. Confirm that the tire size matches the model and wheel diameter, since Metro, Prizm, and Storm use different fitments. If the car has been sitting, also check for flat spots or pressure loss that developed during storage.
A longer trip is the wrong time to discover that an aging compact still has old rubber or a mismatched wheel-and-tire combination. Once the tires pass inspection, give equal attention to brakes, cooling, belts, hoses, and fluid levels because the tire is only one piece of a 1993 Geo’s readiness. The goal is a balanced pre-drive check, not just a quick glance at tread depth.
