The 1981 Toyota Tercel came to market as a compact, efficient front-drive economy car at a time when small imported cars were becoming a familiar part of everyday American driving. Its appeal today often centers on originality, light weight, and the straightforward character that made the Tercel a practical commuter in its day. Tire fitment on the 1981 Toyota Tercel is entirely radial, but size choice varies by sub-model and wheel setup, with both 12-inch and 13-inch applications in play. That means the real decision is matching the exact trim and rim diameter, then choosing the right radial style for road use, appearance, and restoration goals.
Which Tire Size Is Right for The 1981 Toyota Tercel
The 1981 Toyota Tercel uses five primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All of them are radial tires, but the vehicle spans both 12-inch and 13-inch rims, so confirming the car's actual wheel size comes first. Once that is settled, the next step is choosing among the available size formats and product options that suit the car's intended use and presentation.
145R13 is a Euro-metric radial size in which 145 identifies the nominal section width in millimeters, R denotes radial construction, and 13 indicates a 13-inch rim. In this format, the aspect ratio is not written out and is conventionally associated with an 80-series profile. For the 1981 Toyota Tercel, this size keeps a traditional small-car radial presentation, and available options include Blackwall tires from Michelin and Firestone in series such as Michelin XAS-FF and F560 Radial. It is a useful size to evaluate when keeping a narrow, period-style 13-inch radial setup on the correct Tercel configuration.
155R12 is a Euro-metric radial size that uses a 155-millimeter nominal width, radial construction, and a 12-inch rim. Like other Euro-metric sizes without a stated aspect ratio, it is commonly understood as an 80-series-style format. On a 1981 Toyota Tercel, this size matters because it is tied to a different wheel diameter than the 13-inch fitments elsewhere in the range. Buyers considering 155R12 should verify that the car still has its correct 12-inch wheels and has not been changed to a later or alternate rim setup before choosing tires.
145/80R13 is a metric radial size that spells out more of the sizing information than an older Euro-metric code. The 145 is the nominal section width in millimeters, 80 is the aspect ratio, R marks radial construction, and 13 is the rim diameter in inches. For the 1981 Toyota Tercel, this size serves buyers who need a narrow 13-inch radial in a modern stated-aspect-ratio format. It is worth comparing carefully against the car's exact sub-model and current wheel setup, especially if the vehicle has been through prior tire or wheel substitutions.
155R13 is a Euro-metric radial tire size with a nominal 155-millimeter width on a 13-inch rim. Because the aspect ratio is not printed in the size itself, it is generally treated as a Euro-metric radial in the traditional 80-series style. This size gives the 1981 Toyota Tercel a slightly wider 13-inch fitment than 145R13 and is available in Blackwall form from Michelin and Dunlop, including the Michelin XAS-FF and Dunlop SP Sport Aquajet series. It is a sensible choice to review when the car's sub-model calls for a 13-inch radial with period-style sizing and brand selection.
165/70R13 is a metric radial size that uses a 165-millimeter nominal section width, a 70-series aspect ratio, and a 13-inch rim. Compared with the Euro-metric sizes used elsewhere in the 1981 Toyota Tercel lineup, this format reflects a different sizing convention while remaining a radial fitment. Its role is especially important because it applies to a specific sub-model rather than the whole Tercel range. Anyone selecting this size should confirm that the vehicle is the correct configuration and that the wheel and clearance setup still matches that original 13-inch application.
Sub-model fitment on the 1981 Toyota Tercel is not one-size-fits-all. Tire choice depends on identifying the exact trim first, because the covered versions use different radial sizes and, in one case, a different rim diameter.

1981 Toyota Tercel DLX
The 1981 Toyota Tercel DLX uses two different radial tire sizes across its covered configurations, including both 13-inch and 12-inch applications. That makes wheel-diameter confirmation especially important before choosing a replacement tire or comparing the car's current setup to a period-style fitment.
The 1981 Toyota Tercel DLX 3 Dr. Liftback uses 13-inch radial fitments, but it appears with two different size conventions. Tire selection here comes down to matching the exact 13-inch size on the car and then choosing the radial style that best suits use, appearance, and wheel compatibility.
The 1981 Toyota Tercel SR5 is the most straightforward fitment in the group, using a single 165/70R13 radial size. That simplifies the size decision, but the buyer should still confirm the car retains its correct 13-inch wheels before selecting a replacement.
The 1981 Toyota Tercel STD uses 13-inch radial tires, with two size formats associated with the model. The practical task is confirming which 13-inch size is on the car now and whether the goal is a traditional Euro-metric look or a stated-aspect-ratio metric radial.
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 1981 Toyota Tercel?
A 1981 Toyota Tercel can use 145R13, 155R12, 145/80R13, 155R13, or 165/70R13, depending on the exact sub-model and wheel setup. All of these are radial tire sizes, but they are not used universally across the full Tercel range.
The important next step is identifying the exact trim and confirming whether the car has 12-inch or 13-inch wheels. Many older compact cars have had wheels or tires changed over the years, so the best approach is to match the sub-model fitment first, then verify the actual rim diameter on the vehicle before choosing a tire.
What size rim does a 1981 Toyota Tercel use?
The 1981 Toyota Tercel uses either a 12-inch or 13-inch rim, depending on the sub-model and tire size. The 155R12 fitment uses a 12-inch rim, while 145R13, 145/80R13, 155R13, and 165/70R13 all use 13-inch rims.
That split makes rim confirmation one of the most important parts of selecting tires for this car. A Tercel that has been through decades of service may no longer wear its original wheels, so checking the wheel itself before purchase helps avoid choosing the correct tire size for the wrong rim diameter.
Why does the 1981 Toyota Tercel have more than one tire size?
The 1981 Toyota Tercel has more than one tire size because fitment varies by sub-model, and the range includes both 12-inch and 13-inch wheel applications. Some trims also use different size conventions, including Euro-metric radial sizes and metric radial sizes with a stated aspect ratio.
For a buyer, that means tire selection starts with the exact version of the car rather than the model name alone. Matching the sub-model narrows the correct fitment, while checking the current wheel setup helps account for any later wheel swaps or prior tire substitutions that may have changed what is on the car today.
Choosing the Right Tire
What should I consider when choosing a 13-inch tire for a 1981 Toyota Tercel?
Start by confirming which 13-inch size the car actually uses, because a 1981 Toyota Tercel may take 145R13, 145/80R13, 155R13, or 165/70R13 depending on sub-model. After that, compare construction, size format, and whether the goal is a traditional small-car radial appearance or a more modern stated-profile metric tire.
Available 13-inch products also differ by brand, tire series, rim-width specification, weight, and load information where stated. Choosing among them is less about finding a single universal answer and more about matching the tire to the car's wheel dimensions, intended road use, and the look you want the Tercel to carry.
What sidewall styles are available for 1981 Toyota Tercel tires?
The available 1981 Toyota Tercel products shown here use Blackwall sidewalls. That applies to the Michelin, Firestone, and Dunlop options offered in the applicable 13-inch radial sizes.
A Blackwall sidewall suits the clean, understated look many early 1980s compact imports carried on the road. Appearance still should be balanced with fitment details, so once the correct size is confirmed, the next comparison points become brand, tire series, and wheel-width compatibility rather than expecting multiple sidewall treatments within these currently shown options.
What brands offer tires for the 1981 Toyota Tercel?
Michelin, Firestone, and Dunlop offer applicable tires for the 1981 Toyota Tercel in the covered 13-inch radial sizes. Michelin appears in both 145R13 and 155R13, while Firestone is available in 145R13 and Dunlop is available in 155R13.
Brand choice should come after the correct size has been matched to the car, since the Tercel range includes several different fitments. Once that is settled, comparing tire series, sidewall presentation, rim-width requirements, and any stated load details gives a more useful basis for selection than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Toyota Tercel?
A period-style 1981 Toyota Tercel usually starts with matching the exact original fitment format used by the car's sub-model, especially the narrow Euro-metric radial sizes such as 145R13, 155R12, or 155R13 where applicable. Those sizes preserve the small-car radial look associated with the era better than choosing a different size simply because it is familiar today.
Appearance should still be balanced with practicality, particularly on a car that may have seen wheel changes over the years. If originality matters at a high level, compare the car's current wheels and surviving vehicle documentation before settling on a tire, then choose the product whose size and visual presentation best support that goal.
How does tire construction affect the appearance of a restored 1981 Toyota Tercel?
Tire construction is straightforward on the 1981 Toyota Tercel because the covered fitments are all radial. The visual difference comes less from choosing between bias-ply and radial and more from selecting the correct narrow radial size format, sidewall presentation, and overall stance for the specific sub-model.
That makes size accuracy especially important on a restored compact import, where small changes in width or profile can noticeably change the car's look. A Blackwall radial in the proper 12-inch or 13-inch size usually supports a tidy period-style appearance, provided the wheel diameter and fitment match the car's actual configuration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Toyota Tercel?
Yes, modifications can affect tire fitment on a 1981 Toyota Tercel. Wheel swaps, suspension changes, altered ride height, or prior conversions between 12-inch and 13-inch setups can all change what size is currently on the car and whether a given replacement tire still has proper clearance.
That is why the car should be checked as it sits, not only by model year and name. Looking at wheel diameter, wheel width, steering clearance, and fender space before purchase helps prevent mismatches, especially on older cars that may have passed through several owners and accumulated changes over time.
What should I inspect before driving a 1981 Toyota Tercel on new tires?
Before driving a 1981 Toyota Tercel on new tires, inspect the wheels for correct diameter and condition, confirm the tires are mounted in the correct size, and check inflation pressure. It is also wise to look over the suspension and steering components so the tires are not being asked to work around worn mechanical parts.
A short road test should be preceded by a visual clearance check at full steering lock and over normal suspension movement. On an older Tercel, it also helps to inspect for uneven tread wear on the old tires, because that can point to alignment or chassis issues that should be corrected before regular road use.
How should tires on a collector 1981 Toyota Tercel be maintained?
Tires on a collector 1981 Toyota Tercel should be checked regularly for pressure, cracking, bulges, cuts, irregular wear, and signs of slow air loss. Cars that are driven infrequently need this attention even more, because age and storage conditions can affect tire condition long before tread is worn down.
Proper storage helps preserve the tires between drives, especially when the car is kept away from prolonged sunlight, excess heat, moisture, and ozone sources. It also makes sense to inspect the sidewalls and contact patch before any longer outing, since a lightly used classic compact may spend far more time parked than it does on the road.
