The 1981 Plymouth Horizon came from an era when compact front-wheel-drive hatchbacks had become practical everyday transportation, and the Horizon stood out for simple packaging, good urban manners, and economy-minded appeal. Today, surviving examples are often kept as honest survivors or light restorations rather than heavily modified show cars. Tire choice centers on two radial sizes, 155/80R13 and 165/75R13, both built for 13-inch wheels. Within those sizes, the decision leans more toward appearance and product selection, especially whitewall treatment and brand, than toward vintage bias-ply versus radial debates. That makes it important to confirm the actual wheel and existing setup before choosing a tire for regular road use or a restoration-minded presentation.
Which Tire Size Is Right for The 1981 Plymouth Horizon
The 1981 Plymouth Horizon uses two primary tire sizes, and both are radial tires for 13-inch rims. Because the Base and Miser sub-models can use either size, the key step is confirming what is actually on the car now, especially if wheels have been changed over the years. Once size is confirmed, the decision usually comes down to sidewall style, brand, rim-width compatibility, and the look you want the car to carry.
155/80R13 is a metric radial size in which 155 refers to nominal section width in millimeters, 80 is the aspect ratio, R identifies radial construction, and 13 is the wheel diameter in inches. On a 1981 Plymouth Horizon, it represents a narrow compact-car fitment that suits the car's original small-wheel character. Available choices include Travelstar, BFGoodrich, Maxxis, and Tornel, with narrow whitewall and wide whitewall sidewall treatments offered across several tire series. This size is worth considering when you want to stay with a traditional compact radial footprint and compare appearance details as closely as fitment details.
165/75R13 is also a metric radial size, with 165 as the nominal section width in millimeters, 75 as the aspect ratio, R for radial construction, and 13 for the wheel diameter. For the 1981 Plymouth Horizon, it is another primary 13-inch fitment rather than an aftermarket-only substitute. Since both Horizon sub-models can use this size, the practical question is whether your car's current wheels and setup were intended for 165/75R13. Choosing this size makes the most sense after confirming the existing wheel and tire combination and checking that the overall stance and clearance remain appropriate.
Tire fitment is fairly straightforward across the covered 1981 Plymouth Horizon sub-models because both the Base and Miser can use the same two radial tire sizes. Even so, checking the exact sub-model and the car's present wheel setup helps avoid ordering a size that does not match what is already on the vehicle.

1981 Plymouth Horizon Base
The 1981 Plymouth Horizon Base can use either of the two primary 13-inch radial tire sizes offered for this model year. That gives the owner some flexibility, but the right choice still depends on confirming which size is already fitted and then selecting the preferred whitewall style, brand, or overall presentation.
The 1981 Plymouth Horizon Miser also uses the same pair of 13-inch radial fitments found on the Base model. Tire selection is less about sub-model-specific construction changes and more about matching the car's current wheel setup while deciding how plain or restoration-oriented the finished look should be.
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.

These FAQs for the 1981 Plymouth Horizon focus on the two primary 13-inch radial sizes, shared sub-model fitment, whitewall tire choices, and the wheel, clearance, and maintenance checks that matter before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 1981 Plymouth Horizon?
The 1981 Plymouth Horizon uses two primary tire sizes: 155/80R13 and 165/75R13. Both are radial tires designed for 13-inch wheels, and both appear across the covered Horizon sub-models rather than being tied to one trim only.
That means the main task is confirming which size is actually on the car before choosing a replacement. Many older compact cars have seen wheel or tire changes over time, so checking the existing sidewall marking, wheel diameter, and general clearance is more useful than assuming every Horizon still carries its original setup.
What size rim does a 1981 Plymouth Horizon use?
The tire fitments for the 1981 Plymouth Horizon use a 13-inch rim diameter. Both 155/80R13 and 165/75R13 are built around that same 13-inch wheel size, so the rim diameter remains consistent even though the section width and aspect ratio differ slightly.
Rim diameter is only one part of the fitment picture, though. Wheel width still matters, especially when comparing specific tire products, so it is smart to verify the actual wheel on the car before replacement. Matching the correct 13-inch diameter first prevents the most basic fitment mistake and narrows the decision to the proper tire size.
Do all 1981 Plymouth Horizon sub-models use the same tire size?
The covered 1981 Plymouth Horizon sub-models share the same two primary tire sizes. Both the Base and Miser can use 155/80R13 and 165/75R13 radial tires, so fitment is shared rather than split into different sub-model-only sizes.
That shared fitment makes sub-model identification less complicated, but it does not eliminate the need to inspect the individual car. A Horizon that has been fitted with different wheels over the years may favor one size over the other, so the best approach is to confirm the wheel and current tire marking before choosing between the available replacements.
Choosing the Right Tire
What should I consider when choosing a 155/80R13 tire for a 1981 Plymouth Horizon?
Start with the basics: confirm that 155/80R13 is the size already used on your 1981 Plymouth Horizon and that the tire is intended for a 13-inch wheel. Then compare radial construction details such as rim-width specification, load figure where stated, sidewall style, and how closely the tire's appearance matches the look you want.
This size has several whitewall-oriented choices, so appearance can shape the decision as much as fitment. A narrow whitewall gives a restrained period feel, while a wider whitewall changes the car's visual balance more noticeably. Brand and series differences matter too, but the smartest comparison starts with wheel compatibility and the car's intended use.
What sidewall styles are available for 1981 Plymouth Horizon tires?
The available 155/80R13 tires for a 1981 Plymouth Horizon include narrow whitewall and wide whitewall sidewall styles. That gives the car owner a choice between a subtler traditional look and a more prominent whitewall presentation without moving away from the correct basic radial size format.
Sidewall style changes the car's appearance more than many buyers expect, especially on a small 13-inch wheel. A narrow whitewall tends to suit an understated survivor or everyday driver look, while a wide whitewall leans more restoration-minded. Once the size is confirmed, sidewall treatment becomes one of the most visible ways to shape the finished result.
What brands offer tires for the 1981 Plymouth Horizon?
Among the available 155/80R13 options for the 1981 Plymouth Horizon, brands include Travelstar, BFGoodrich, Maxxis, and Tornel. Those choices also span different tire series, including UN106, Silvertown Radial, Classic Whitewall MA-1, and Tornel Classic.
The practical value of multiple brands is the ability to compare more than just the name on the sidewall. Whitewall width, rim-width specification, load figure where stated, and overall visual character can vary from one product to another. Once the correct size is established, those differences usually matter more than trying to treat every brand option as interchangeable.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Plymouth Horizon?
A period-style 1981 Plymouth Horizon tire choice starts with using one of the vehicle's proper 13-inch radial sizes, either 155/80R13 or 165/75R13, depending on the setup on the car. From there, the appearance decision usually centers on whether a whitewall treatment suits the look you want to recreate.
For many Horizon owners, the goal is not concours-level originality but a believable early-1980s presentation. Narrow whitewalls keep the look restrained, while a wider whitewall makes a stronger styling statement. When exact originality matters, it is worth checking period brochures, marque references, or surviving examples before deciding on brand and sidewall style.
Does correct tire fitment matter for a 1981 Plymouth Horizon restoration?
Correct tire fitment matters on a 1981 Plymouth Horizon restoration because tire size has a direct effect on stance, wheel appearance, and the overall character of the finished car. Using one of the proper 13-inch radial sizes keeps the restoration grounded in the way the Horizon was intended to sit and look.
Appearance is only part of the story. The wrong size can also create avoidable clearance or wheel-compatibility issues, especially on a small front-wheel-drive compact. Even on a casual restoration, it is smart to verify the wheel diameter, confirm the size already used on the vehicle, and then choose a sidewall style that supports the car's desired presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Plymouth Horizon?
Yes, modifications can affect tire fitment on a 1981 Plymouth Horizon even when the original tire sizes are straightforward. Aftermarket wheels, changed wheel width, suspension alterations, or body and brake changes can influence which of the two primary 13-inch tire sizes works best on the individual car.
That is why the present setup matters more than assumptions based on model year alone. A Horizon with non-original wheels may still use a 13-inch rim but need closer attention to width and clearance. Inspecting the current tires, measuring the wheel where needed, and checking for steering or fender interference can prevent an expensive mismatch.
What should I inspect before driving a 1981 Plymouth Horizon on new tires?
Before driving a 1981 Plymouth Horizon on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and check for enough clearance at the fenders and steering components. It is also wise to look over the suspension and alignment condition so the new tires are not immediately compromised.
A road-ready inspection should also include tire pressure, valve stems, and a quick check for rubbing once the car is on the ground. On an older Horizon that may have spent long periods parked, dried rubber parts or worn suspension pieces can show up only after fresh tires are installed, so a cautious first drive is a sensible final step.
How should 155/80R13 tires on a collector 1981 Plymouth Horizon be maintained?
155/80R13 tires on a collector 1981 Plymouth Horizon should be maintained with regular pressure checks, visual inspections for cracking or bulges, and periodic tread and wear-pattern review. Even low-mileage collector cars need routine tire attention because age and storage conditions can affect a tire long before the tread is worn out.
Storage practices matter almost as much as mileage on a car like this. Keeping the Horizon away from prolonged sunlight, excess heat, standing moisture, and ozone sources helps preserve the tire sidewalls. It also helps to inspect the tires before every meaningful drive, since a lightly used collector car can hide air loss or age-related deterioration.
