The 1981 Honda Civic came from the early front-wheel-drive economy-car era, when compact packaging, low curb weight, and practical daily use defined the car’s appeal. For owners today, that same character makes tire choice especially important, because this Civic can appear with both 12-inch and 13-inch wheel fitments and with either a bias-ply or radial primary size depending on the sub-model. The 1981 Honda Civic spans 6.00-12 bias-ply, 155R12 radial, 145R13 radial, and 155R13 radial applications. Available choices lean toward blackwall radials from brands such as Michelin, Firestone, and Dunlop. The right selection starts with the exact sub-model and wheel diameter before considering appearance, driving use, and construction style.
Which Tire Size Is Right for The 1981 Honda Civic
The 1981 Honda Civic uses four primary tire sizes, and the correct one depends on the exact sub-model and whether the car is equipped with 12-inch or 13-inch wheels. Some versions use a traditional 6.00-12 bias-ply tire, while others use Euro-metric radial sizes such as 155R12, 145R13, or 155R13. Confirming the sub-model and wheel diameter is the first step before comparing available tire brands or construction types.
The 6.00-12 size is a numeric bias-ply format in which the leading number refers to nominal section width in inches and the final number identifies a 12-inch rim. On the 1981 Honda Civic, this is the bias-ply fitment used on the 1300 sub-model, giving it a distinctly earlier small-car tire format than the radial-equipped versions. It differs from the Euro-metric radial sizes used elsewhere in the Civic range, so construction choice is built into the fitment itself. This size is the right starting point for an owner keeping the car in its original-style bias-ply configuration and confirming the car still wears the correct 12-inch wheels.
The 155R12 size is a Euro-metric radial designation, with 155 indicating nominal section width in millimeters, R identifying radial construction, and 12 calling for a 12-inch rim. For the 1981 Honda Civic, this size applies to the 1300 DX and represents a move from the earlier numeric bias-ply format into a more modern small-car radial layout. Its practical role is different from the 13-inch Civic sizes, so wheel diameter matters just as much as the size code itself. This is the fitment to evaluate when the car is a 12-inch-wheel radial Civic rather than a 6.00-12 bias-ply or one of the 13-inch radial versions.
The 145R13 code is a Euro-metric radial size that uses a 145-millimeter nominal section width, radial construction, and a 13-inch rim diameter. On the 1981 Honda Civic, this size is used on the 1500 DX and 1500 GL, placing it with the lighter-section 13-inch radial fitments rather than the 12-inch applications. Available choices in this size include blackwall radial designs from Michelin and Firestone, with differences in tire series, weight, and rim-width specifications. This size is the one to focus on when matching a 13-inch-wheel 1500 Civic and comparing period-style radial options within the proper fitment.
The 155R13 size is a Euro-metric radial format with a 155-millimeter nominal section width, radial construction, and a 13-inch rim requirement. For the 1981 Honda Civic, this fitment belongs to the Base model and stands apart from the narrower 145R13 used on certain 1500 sub-models. In this size, available products include blackwall radials from Michelin and Dunlop, with differences in tire series and supporting specifications that matter to buyers comparing character as well as fitment. This is the correct size to review when the Civic has the Base-model 13-inch wheel setup and the goal is an appropriate radial tire rather than a bias-ply presentation.
Sub-model fitment varies across the 1981 Honda Civic lineup, and tire choice is tied directly to both trim designation and wheel diameter. Checking the exact sub-model matters here because the range includes a 12-inch bias-ply application, a 12-inch radial application, and two different 13-inch radial sizes.

1981 Honda Civic 1300
The 1981 Honda Civic 1300 uses the 6.00-12 bias-ply size, making it the only covered sub-model here with a primary bias-ply fitment. Tire selection centers on preserving that original-style construction approach and confirming the car still carries its 12-inch wheel setup.
The 1981 Honda Civic 1300 DX uses a 155R12 radial tire on a 12-inch rim, separating it from both the 6.00-12 bias-ply 1300 and the 13-inch Civics. That means the key buying decision is choosing the proper 12-inch radial fitment rather than assuming interchangeability with the larger-wheel versions.
The 1981 Honda Civic 1500 DX uses a 145R13 radial tire, placing it with the 13-inch wheel group but not with the wider 155R13 Base fitment. Tire selection should stay centered on that narrower radial size while comparing available blackwall product choices and wheel compatibility.
The 1981 Honda Civic 1500 GL shares the 145R13 radial fitment with the 1500 DX, so tire choice follows the same 13-inch radial path. The practical task is confirming the GL still wears the expected wheel setup, then choosing among the available period-style blackwall radial options in that size.
The 1981 Honda Civic Base uses the 155R13 radial size, which distinguishes it from the narrower 145R13 1500 models and the 12-inch-wheel Civics. Tire selection should focus on that exact 13-inch radial fitment and the available differences in brand and tire series within the size.
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 Honda Civic?
The 1981 Honda Civic uses four primary tire sizes: 6.00-12, 155R12, 145R13, and 155R13. The correct size depends on the exact sub-model. The 1300 uses 6.00-12 bias-ply, the 1300 DX uses 155R12 radial, the 1500 DX and 1500 GL use 145R13 radial, and the Base model uses 155R13 radial.
That means the first step is not choosing a brand or tire series but confirming the Civic’s exact sub-model and whether it has 12-inch or 13-inch wheels. Many older Civics have changed hands, and some may have had wheel swaps over the years, so checking the actual wheel diameter on the car helps prevent ordering the wrong size.
What size rim does a 1981 Honda Civic use?
A 1981 Honda Civic can use either a 12-inch or 13-inch rim, depending on the sub-model and tire size. The 6.00-12 and 155R12 fitments use 12-inch rims, while 145R13 and 155R13 fitments use 13-inch rims. Rim diameter is tied directly to the tire size and cannot be treated as interchangeable.
The practical takeaway is to confirm the wheel diameter on the car before narrowing down tire choices. Even when two sizes look close in width, a 12-inch tire does not belong on a 13-inch wheel, and vice versa. Checking wheel width is also worthwhile when comparing radial products that include published rim-width recommendations.
Why does the 1981 Honda Civic have more than one tire size?
The 1981 Honda Civic has more than one tire size because fitment varies by sub-model. The range includes both 12-inch and 13-inch wheel applications, and it also spans a bias-ply size and several radial sizes. That makes this Civic lineup more varied than a single-size fitment page might suggest at first glance.
For an owner, that variation means the model name alone is not enough to choose a tire. A 1300, 1300 DX, 1500 DX, 1500 GL, and Base model do not all follow the same fitment path. Matching the car’s exact sub-model and wheel setup is the reliable way to narrow the selection before comparing available tires.
Choosing the Right Tire
What should I consider when choosing a 1981 Honda Civic tire?
Start with the exact tire size for the sub-model, then match the wheel diameter and construction type. A 1981 Honda Civic may require a 6.00-12 bias-ply tire or one of three radial sizes: 155R12, 145R13, or 155R13. Once the core fitment is confirmed, product choice becomes a matter of brand, tire series, and stated wheel-compatibility details.
An owner choosing among available products should also consider how the car will be used. A restoration-minded Civic may call for a traditional-looking fitment approach, while a road-driven example may place more emphasis on staying with the proper radial size and checking wheel width, load-related specifications, and overall condition of the suspension and steering.
What sidewall styles are available for 1981 Honda Civic tires?
The available 13-inch tires for the 1981 Honda Civic are blackwall radials. That applies to the product choices offered in both 145R13 and 155R13, including Michelin, Firestone, and Dunlop options. For buyers trying to keep a clean small-car look, blackwall remains the defining sidewall presentation in the currently available assortment.
That sidewall consistency shifts the decision away from whitewall or stripe treatment and toward fitment, brand, and tire series. The important next check is making sure the Civic uses the exact 13-inch radial size tied to its sub-model, since a correct sidewall appearance does not make a different diameter or width appropriate for the car.
What brands offer tires for the 1981 Honda Civic?
Michelin, Firestone, and Dunlop all appear in the available product range for 1981 Honda Civic fitments. Michelin is offered in both 145R13 and 155R13, Firestone appears in 145R13, and Dunlop appears in 155R13. Those brand choices are tied to specific sizes, so the right fitment still comes before comparing nameplates.
The useful way to compare them is by staying inside the correct tire size for the car and then reviewing the differences in tire series, published rim-width guidance where available, and other supporting specifications such as load figures or weight. Brand alone does not determine suitability if the Civic’s sub-model or wheel diameter points to another size.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Honda Civic?
A period-style 1981 Honda Civic tire choice starts with using the exact size and construction that belongs on the specific sub-model. That could mean a 6.00-12 bias-ply on a Civic 1300 or one of the proper Euro-metric radial sizes on a 1300 DX, 1500 DX, 1500 GL, or Base model. Matching that baseline keeps the car visually and mechanically closer to its era.
After the fitment is right, appearance becomes more about the overall presentation than about forcing one universal solution across the lineup. Blackwall radials suit the available 13-inch product range, while the 6.00-12 bias-ply carries a distinctly earlier look. Owners pursuing strict originality should compare their car against marque references and surviving examples before finalizing details.
Does correct tire fitment matter for a 1981 Honda Civic restoration?
Correct tire fitment matters on a 1981 Honda Civic restoration because the car’s proportions, stance, and driving character depend heavily on using the proper size and wheel diameter. This model year spans both 12-inch and 13-inch applications, plus a split between bias-ply and radial construction. Using the wrong category can change the look of the car as much as the mechanical fitment.
A restoration-minded owner should confirm the sub-model first, then verify the wheels actually on the car before choosing tires. That helps avoid common problems such as selecting a 13-inch radial for a car still set up for 12-inch wheels, or replacing a bias-ply application with a radial size that changes the visual character without careful review.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Honda Civic?
Yes, modifications can affect tire fitment on a 1981 Honda Civic. Aftermarket wheels, wheel-width changes, altered offsets, lowered suspension, or body changes can all influence how a 6.00-12, 155R12, 145R13, or 155R13 tire sits in the car. Even when the nominal size is correct, the overall combination may no longer match the original wheel and clearance relationship.
That is why a modified Civic should be checked at the wheel itself, not just by model name. Measure the actual rim diameter and width, inspect clearance at full steering lock, and account for any suspension changes before choosing a replacement tire. Older compact cars have limited space, so small setup changes can matter more than they do on larger vehicles.
What should I inspect before driving a 1981 Honda Civic on new tires?
Before driving a 1981 Honda Civic on new tires, inspect the wheels for the correct diameter and sound condition, then confirm the tires are mounted in the proper size for the sub-model. It is also smart to check valve stems, inflation pressure, lug torque, and general wheel integrity, especially on a car that may have seen long-term storage or infrequent use.
A broader road-use check should include steering and suspension condition, brake function, and visible clearance around the fenders and inner wheel housings. On an older Civic, worn bushings or sagging springs can affect how the tire sits once the car is back on the road. A short test drive and reinspection can catch problems early.
How should tires on a collector 1981 Honda Civic be maintained?
Tires on a collector 1981 Honda Civic should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Watch for cracking, bulges, cuts, uneven wear, or signs of slow air loss. On a low-mileage car, age and storage conditions often matter just as much as tread depth, since many collector cars spend long periods parked.
Good maintenance also means keeping the Civic away from prolonged sun exposure, excess moisture, and ozone-producing equipment when stored. Rolling the car periodically or moving it slightly can help avoid long-term flat spotting. Before any extended drive, recheck inflation, inspect the sidewalls closely, and make sure the wheels and suspension still support the tire evenly.
