1979 Dodge St Regis Tires

The 1979 Dodge St Regis is associated with two primary tire sizes: 175/75R15 and 205/75R15. Both are radial tires designed for 15-inch rims, and both are tied to the St Regis Base configuration rather than being split into separate sub-model lines on this page.

That means the safest starting point is the car itself. Check the wheel diameter and the size of the tires already on the vehicle before choosing a replacement, especially on an older sedan that may have seen wheel changes over time. Once the actual setup is confirmed, selection comes down to the appropriate size and the appearance you want.

The tire fitments associated with the 1979 Dodge St Regis use a 15-inch rim diameter. Both 175/75R15 and 205/75R15 are built around that same 15-inch wheel size, so the rim diameter remains consistent even though the tire sizes themselves differ.

Rim diameter is only one part of the fitment picture. A St Regis may still need wheel-width confirmation, particularly if it has replacement wheels or has been stored and revived after many years. Matching the tire to the correct 15-inch wheel and checking clearance around the suspension and fenders helps avoid choosing a size by model name alone.

The 1979 Dodge St Regis Base is associated with both 175/75R15 and 205/75R15 radial tire sizes. In other words, the Base designation by itself does not reduce the fitment to one single tire size, even though all of the fitments remain on a 15-inch rim diameter.

That makes the actual wheel-and-tire setup on the car more important than the sub-model name. A quick inspection of the wheel diameter, current tire size, and available clearance will usually answer the fitment question faster than relying on trim wording alone. This is especially helpful on surviving full-size cars that may have been altered over the years.

Start with the basics: confirm that the car is actually using 205/75R15 tires on 15-inch wheels. From there, the major differences are brand, tire series, sidewall style, and wheel-width compatibility, since available 205/75R15 options include several classic-style radial lines with different visual treatments.

A St Regis restored to a traditional boulevard look may point toward a whitewall, while a more custom appearance may lean toward goldline or redline. It also helps to compare rim-width guidance where shown, along with load figures and overall product character. Choosing well in this size is less about finding any radial and more about matching the car's setup and presentation.

The visible sidewall choices for 1979 Dodge St Regis tires in 205/75R15 include narrow whitewall, wide whitewall, goldline, and redline. Those options appear across several radial product lines, giving the car owner a meaningful appearance choice even while staying within a proper 15-inch classic-style replacement format.

Sidewall treatment has a big effect on how a late-1970s full-size Dodge presents itself. A whitewall usually supports a more formal and traditional look, while goldline and redline create a sportier or more customized visual impression. Before deciding purely on appearance, make sure the size and wheel compatibility are correct for the car's existing setup.

Available 205/75R15 tires for the 1979 Dodge St Regis come from BFGoodrich, American Classic, Coker Classic, Tornel, Maxxis, and Travelstar. Those brands cover several classic-style radial series rather than one single uniform product type, so the choice is broader than just picking a name on the sidewall.

Brand should be considered alongside tire series, sidewall styling, and wheel fitment details. Some options emphasize a traditional whitewall presentation, while others add goldline or redline treatment for a different look. Since this page also associates the St Regis with 175/75R15, confirming the size on the car comes before comparing brands within the 205/75R15 group.

A period-style 1979 Dodge St Regis tire choice starts with the correct radial size on a 15-inch rim, then moves to visual presentation. Since the available assortment is concentrated in 205/75R15, that size offers the clearest path to a restoration-oriented look with classic sidewall treatments and multiple brand and series choices.

Whitewall options usually fit the formal character many owners want from a late-1970s full-size sedan, while goldline or redline can shift the look in a more personalized direction. Exact originality claims should be verified against marque literature or other vehicle-specific references, but the right size and a traditional sidewall style provide a strong visual starting point.

For the 1979 Dodge St Regis, construction is straightforward because the associated primary tire sizes are radial rather than bias-ply. That means the appearance question is less about choosing between two vintage construction styles and more about selecting the right radial size and the sidewall treatment that complements the car's late-1970s character.

A restored St Regis can look noticeably different depending on whether it wears a narrow whitewall, wide whitewall, goldline, or redline. The tire still needs to suit the actual wheel on the car, but once fitment is confirmed, construction is already settled and the visual emphasis moves to profile and sidewall presentation rather than bias-ply versus radial styling.

Yes. Even though the 1979 Dodge St Regis is associated with 175/75R15 and 205/75R15 on 15-inch rims, modifications can change what works on an individual car. Aftermarket wheels, altered wheel width, suspension changes, or body and brake updates can all affect clearance and the tire size that makes sense.

A St Regis that has been lowered, fitted with different wheels, or rebuilt with non-original components should be measured before new tires are chosen. Check wheel diameter and width first, then look at steering clearance, fender room, and how the tire sits in the wheel opening. That process is more reliable than assuming every surviving car remains stock.

Before driving a 1979 Dodge St Regis on new tires, inspect the wheels, lug hardware, valve stems, and the condition of the suspension and steering components. The car should also be checked for proper tire pressure, even tread seating, and adequate clearance at full steering lock and through normal suspension movement.

An older full-size sedan may have age-related issues that new tires will not solve by themselves. Look for play in the front end, uneven ride height, and any signs that previous tires rubbed or wore irregularly. A short local drive followed by a second inspection can reveal air loss, contact marks, or balance concerns before longer road use.

Tires on a collector 1979 Dodge St Regis should be kept properly inflated, inspected regularly, and protected from long periods of heat, sunlight, and ozone exposure. Since collector cars are often driven less, sidewall aging, flat spotting, and slow air loss can become just as important as visible tread wear.

Regular checks should include tread condition, cracking, bulges, cuts, and any change in how the car steers or rides. It also helps to move the car periodically and store it on a clean, dry surface. Maintenance matters whether the St Regis wears 175/75R15 or 205/75R15, because long idle periods can age a tire before the tread is actually used up.
