The 1979 American Motors AMX came at the end of AMC’s performance-leaning era, carrying the AMX name on a compact platform that still appealed to buyers who wanted sporty styling with late-1970s road manners. For owners today, tire selection is more about getting the fitment and look right than sorting through multiple factory sizes. This AMX uses a single primary tire size, ER60-14, in radial construction on a 14-inch rim. That keeps the fitment straightforward, while still leaving room to think about period-style appearance, driving use, and the condition of the wheels before putting the car back into regular road service.
Which Tire Size Is Right for The 1979 American Motors AMX
The 1979 American Motors AMX uses one primary tire size: ER60-14. It is a radial fitment for a 14-inch rim, and the covered AMX Base model uses the same size. That means the main decision is not which size fits, but which ER60-14 tire best matches the car’s intended appearance, road use, and wheel condition.
ER60-14 is an alphanumeric radial size, where the letter code identifies the tire’s size class, the R indicates radial construction, the 60 designates its profile family, and 14 is the rim diameter in inches. On the 1979 American Motors AMX, this is the primary fitment and reflects the more modern tire-sizing conventions used on late-1970s performance-oriented cars. Buyers looking at this size should focus on preserving the proper 14-inch wheel fitment, comparing tread and sidewall presentation, and confirming that the car has not been altered in ways that affect clearance or overall stance.
Tire fitment is straightforward across the covered 1979 American Motors AMX sub-models. The key point is simply confirming that the car is the AMX Base configuration and still carries the correct 14-inch wheel setup before choosing an ER60-14 tire.

Frequently Asked Questions
Owners researching 1979 American Motors AMX tires usually want clear answers on ER60-14 sizing, 14-inch rim fitment, construction, appearance, and what to inspect before driving a collector-era car on fresh tires.
Tire Size & Fitment
What tire size fits a 1979 American Motors AMX?
The 1979 American Motors AMX uses ER60-14 tires. That is the primary fitment for this model year and combines a radial construction with a 14-inch rim diameter, making it a late-1970s performance-era size rather than an earlier numeric or bias-ply format.
Using the correct size starts with confirming that the car still has its proper 14-inch wheels. If the AMX has been modified with aftermarket wheels, suspension changes, or body alterations over the years, those changes can affect clearance and overall fit even when the tire size itself is correct.
What size rim does a 1979 American Motors AMX use?
The 1979 American Motors AMX uses a 14-inch rim with its ER60-14 tire size. The 14 at the end of the tire code refers to the wheel diameter, so matching the tire to a 14-inch wheel is essential before any other selection decisions are made.
Wheel diameter is only part of the fitment picture, especially on an older car. It is also wise to inspect the wheel’s width, condition, and true seating surfaces, particularly if the car has sat for long periods or has changed hands several times since new.
Does the 1979 American Motors AMX Base use the same tire size?
Yes. The 1979 American Motors AMX Base uses the same ER60-14 radial tire size. That keeps fitment simple within the covered sub-model range, since there is not a second primary tire size to sort through for this particular AMX configuration.
Even with shared fitment, it still makes sense to verify the actual wheels on the car before ordering tires. Collector vehicles are often updated with replacement wheels, altered ride height, or brake changes, and those details can influence how an ER60-14 tire sits in the wheel opening.
Choosing the Right Tire
What should I consider when choosing an ER60-14 tire for a 1979 American Motors AMX?
Start with the basics: the tire should be the correct ER60-14 size and intended for a 14-inch wheel. Since the fitment itself is straightforward on a 1979 American Motors AMX, the next considerations become tire construction style, overall appearance, and whether the tire suits a restoration-minded presentation or a more regular road-use pattern.
Beyond the size code, pay attention to the condition and dimensions of the wheels actually on the car. An AMX that has seen aftermarket wheel changes, suspension work, or long storage may need extra clearance and wheel-condition checks before a new set of tires is put into service.
How do I choose between available ER60-14 tires for a 1979 American Motors AMX?
Choosing among ER60-14 tires usually comes down to matching the tire to the car’s purpose. A restoration-oriented AMX may call for a more traditional visual presentation, while a driver-focused car may place more emphasis on road use, maintenance habits, and how the tire complements the car’s current wheel setup.
It helps to compare the tire’s appearance and any construction details against the condition of the rest of the vehicle. A fresh set of tires can look out of place on bent, corroded, or incorrectly sized wheels, so the smartest comparison is not tire against tire alone, but tire against the actual AMX being outfitted.
Why is ER60-14 important to keep correct on a 1979 American Motors AMX?
ER60-14 is important because it establishes the basic tire and wheel relationship for the 1979 American Motors AMX. Keeping the correct primary size helps preserve the car’s intended fitment character and avoids turning a simple replacement into a broader clearance or wheel-compatibility problem.
A change away from the proper size can affect how the tire sits in the wheel opening and how closely the setup matches the car’s late-1970s look. Before departing from ER60-14, it is wise to inspect steering clearance, suspension condition, and the actual wheels mounted on the car.
Restoration & Appearance
Which tire should I choose for a period-style 1979 American Motors AMX?
A period-style 1979 American Motors AMX should begin with the correct ER60-14 size, since that is the primary fitment for the car. Starting with the right size preserves the late-1970s character of the AMX better than jumping immediately to an unrelated modern replacement format.
After size is confirmed, the best choice depends on how authentic-looking the finished car needs to be. Appearance-focused owners often compare sidewall presentation, tread style, and how the tire works visually with the wheel design, while exact originality questions are best checked against marque-specific restoration references.
Does correct tire fitment matter for a 1979 American Motors AMX restoration?
Yes, correct tire fitment matters on a 1979 American Motors AMX restoration because the tire has a major effect on stance, wheel opening fill, and the overall late-1970s presentation of the car. ER60-14 is the right starting point when the goal is to keep the AMX visually coherent.
A restored car can lose some of its proper character if the tires are noticeably off in size or profile, even when they physically mount to the wheel. Matching the tire to the wheel, the body stance, and the intended finish level of the restoration produces a more convincing result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1979 American Motors AMX?
Yes, modifications can affect tire fitment on a 1979 American Motors AMX even when ER60-14 is the correct original-size starting point. Aftermarket wheels, altered wheel width, suspension changes, ride-height adjustments, and brake conversions can all change how much room the tire has at the fender and steering components.
That is why the car itself should be checked, not just the size code on paper. Looking at wheel diameter, actual wheel width, turning clearance, and visible signs of rubbing helps prevent surprises once the tires are mounted and the AMX is driven at normal road speeds.
What should I inspect before driving a 1979 American Motors AMX on new tires?
Before driving a 1979 American Motors AMX on new tires, inspect the wheels for damage, corrosion, and proper bead seating surfaces. It also helps to check lug hardware, valve stems, visible suspension wear, and whether the tires clear the fenders and steering components with the car at rest and in motion.
A collector-era car can look ready for the road while still hiding age-related issues. Tire pressure, alignment condition, brake behavior, and any signs of uneven ride height deserve attention before a longer drive, especially if the AMX has been stored for extended periods between outings.
How should ER60-14 tires on a collector 1979 American Motors AMX be maintained?
ER60-14 tires on a collector 1979 American Motors AMX should be maintained with regular pressure checks, visual inspections, and sensible storage habits. Sidewall cracking, cuts, bulges, air loss, and irregular tread wear are all worth watching closely, particularly on a car that is driven infrequently.
Good maintenance also means protecting the tires from prolonged heat, direct sunlight, moisture, and ozone exposure during storage. Even when tread wear is low, age and inactivity can affect an older collector vehicle’s tires, so routine inspections matter just as much as mileage on the road.
