1980 Dodge St. Regis Tires

The 1980 Dodge St. Regis uses two primary tire sizes: 195/75R15 and 205/75R15. Both are radial tire fitments built for 15-inch rims, and both are associated with the St. Regis Base. That means the car was not limited to one single size across every example still on the road today.

The practical step is to confirm which size is already mounted and whether the wheels on the car are still the intended 15-inch setup. A St. Regis that has had wheel changes over the years may not match another car exactly, so replacement selection should begin with the current wheel diameter, tire size, and available clearance rather than assumption.

The 1980 Dodge St. Regis uses a 15-inch rim diameter with both of its primary tire sizes. The two fitments, 195/75R15 and 205/75R15, are both built around that same 15-inch wheel diameter, so the key distinction is tire size rather than a change in rim diameter between fitments.

Rim diameter is only part of the picture, so it is still smart to confirm the wheel itself before replacing tires. Width can matter as much as diameter, especially when comparing available products, and any aftermarket wheel change can alter the range of acceptable tires even when the car still wears a 15-inch rim.

The 1980 Dodge St. Regis is associated with both 195/75R15 and 205/75R15 radial tires, even within the Base sub-model. In practical terms, that means owners may encounter more than one correct primary fitment when looking at replacement tires for this car, rather than one universal size applied to every surviving example.

That makes the first decision straightforward: identify what is actually on the car now and confirm the wheel setup before choosing a replacement. Once the size is settled, the comparison shifts to details such as sidewall style, tire series, and brand choice instead of trying to force one size onto a car that may already be set up for the other.

Start with the correct primary size for the car as it sits today, since the 1980 Dodge St. Regis uses either 195/75R15 or 205/75R15. Both are 15-inch radial fitments, so the first concern is matching the tire to the current wheel and size setup rather than picking by appearance alone.

Once size is confirmed, compare the details that affect how the car looks and how the tire matches the wheel. Sidewall treatment, rim-width compatibility, load figures where stated, and the character of the tire series all matter. A formal sedan like the St. Regis can look noticeably different depending on whether it wears a narrow whitewall, wide whitewall, goldline, or redline.

Sidewall choices for the 1980 Dodge St. Regis include narrow whitewall, wide whitewall, goldline, and redline, depending on the tire size and product line selected. The 195/75R15 offerings focus on narrow and wide whitewalls, while 205/75R15 adds more visual variety through goldline and redline options.

That sidewall choice shapes the car's presentation as much as the tire size itself. A whitewall usually supports a more traditional full-size sedan look, while goldline or redline changes the visual tone without changing the basic 15-inch radial fitment. Choosing among them should come after confirming the correct size, since appearance options vary by tire size and series.

Tires for the 1980 Dodge St. Regis are available from Coker Classic, American Classic, BFGoodrich, Tornel, Maxxis, and Travelstar across the supported 15-inch radial sizes. Brand availability depends on size, with 205/75R15 offering the broadest spread of choices and 195/75R15 centering on Coker Classic and American Classic options.

Brand should be compared alongside tire series, sidewall style, and wheel compatibility rather than treated as the only decision. Some products emphasize classic whitewall presentation, while others expand the styling range with goldline or redline treatments. The better approach is to narrow the tire size first, then compare which brand offers the look and specifications that suit the car.

A period-style 1980 Dodge St. Regis tire choice starts with the car's actual primary size, either 195/75R15 or 205/75R15, followed by a sidewall treatment that matches the kind of presentation you want. Both sizes are radial, and available products include traditional-looking whitewall options that suit a formal full-size sedan especially well.

The visual difference between a narrow and wide whitewall can be substantial on a car from this era, so appearance deserves real attention once fitment is confirmed. When exact originality matters, compare the car's surviving details with marque references or period photography. For many owners, the right answer is the tire that preserves the proper size and the most appropriate overall look.

On a restored 1980 Dodge St. Regis, construction is less about bias-ply versus radial debate and more about choosing the right radial style within the proper size. This car's primary fitments are radial, so the appearance difference comes mainly from profile, sidewall treatment, and tire series rather than from switching between completely different construction eras.

That makes the visual decision more refined than dramatic. A wide whitewall can reinforce the car's formal luxury-sedan presence, while a narrow whitewall, goldline, or redline can shift the impression noticeably. Restoration-minded buyers usually get the best result by confirming the correct tire size first, then selecting the sidewall style that best matches the car's finish and stance.

Yes, modifications can affect tire fitment on a 1980 Dodge St. Regis even though the original primary sizes are 195/75R15 and 205/75R15 on 15-inch rims. Wheel changes, altered ride height, suspension work, or body modifications can change how much room the tire has and what size works comfortably on the car.

That matters most on a car that has changed hands several times or no longer wears its original wheel setup. Measure the installed wheel diameter and width, check steering and fender clearance, and look at how closely the current tires sit to suspension components. A replacement should match the actual car in front of you, not just the model name on paper.

Before driving a 1980 Dodge St. Regis on new tires, inspect the wheels for damage, confirm the tire size matches the intended 15-inch setup, and make sure the tires are seated and inflated properly. It also helps to look over the suspension and steering for looseness that could affect how the new tires track on the road.

A short test drive should include listening for rubbing, checking straight-line behavior, and confirming there is no contact at full steering lock. After the first miles, recheck air pressure and look for any unusual marks on the sidewalls or tread. Collector-era cars often reveal fitment or chassis issues only once the fresh tires are carrying real road load.

Collector-car tires on a 1980 Dodge St. Regis should be maintained with regular pressure checks, periodic visual inspection, and attention to age as well as tread depth. Whether the car wears 195/75R15 or 205/75R15 radials, low annual mileage does not prevent rubber from aging, drying, or developing sidewall issues over time.

Storage conditions matter on a car that spends long periods parked. Keep the St. Regis away from prolonged sunlight, moisture, and ozone sources, and inspect for cracking, bulges, cuts, or slow air loss before road use. Even a good-looking tire deserves a close look before a longer drive, especially if the car has been sitting through a season or more.
