1958 Dodge Royal Tires

The 1958 Dodge Royal uses two primary tire sizes: 800-14 and 850-14. Both are bias-ply fitments and both use a 14-inch rim, so the right choice is not tied to a different wheel diameter so much as the size the car is presently set up to use.

Since both sizes appear across the covered Royal sub-models, the safest next step is to verify the wheel width, the size already mounted, and the visual stance you want. A car restored around one size should not automatically be switched to the other without checking wheel compatibility and body clearance.

The 1958 Dodge Royal uses a 14-inch rim with its primary tire fitments. Both 800-14 and 850-14 are built around that same rim diameter, which keeps wheel diameter simple even though there are two tire sizes to choose from.

Rim diameter is only part of the fitment picture, especially on a collector car that may have changed wheels over time. It is still important to confirm the wheel’s actual width and compare it with the tire being considered, particularly if the car has aftermarket wheels or a different tire size already installed.

The covered 1958 Dodge Royal sub-models share the same overall tire-size pattern. Both the All Except Wagon and Wagon versions use 800-14 and 850-14 bias-ply sizes, so there is not a separate wagon-only or non-wagon-only tire size in this fitment group.

That does not mean every individual car should automatically move between those two sizes without inspection. The practical question is which size your Royal currently wears and whether the wheel width, overall appearance, and available clearance support staying with that setup or making a carefully checked change.

For the 1958 Dodge Royal, 800-14 is a primary bias-ply tire size. It is part of the car’s original fitment style and is available in traditional late-1950s presentations such as blackwall, narrow whitewall, and wide whitewall depending on the product chosen.

A radial alternative can be considered, but the original 800-14 designation itself is not the radial size. Buyers trying to keep the car’s period-style look often stay with bias-ply construction, while drivers considering a conversion should compare wheel width, overall dimensions, and clearance before making the change.

Radial equivalents for 800-14 include 205R14, P215/75R14, P225/70R14, and 800R14 as a bias-look radial. Radial equivalents for 850-14 include 215R14, P225/75R14, and P235/70R14. These options cover 80-series metric, 75-series P-metric, and 70-series P-metric formats, with a bias-look radial available for 800-14.

Each equivalent should be treated as an alternative, not an automatic substitute. The stated rim-width range is 5 to 7 inches, and the final choice still needs to be checked against the Dodge’s actual wheels, tire-to-body clearance, and the appearance you want from the car.

A 1958 Dodge Royal owner considering a radial conversion should begin by confirming the current primary size, wheel diameter, and wheel width. For 800-14 and 850-14, the available radial equivalents use the same 14-inch rim diameter, but they appear in several different sizing formats that need to be evaluated carefully.

The important follow-up is comparing the chosen radial against the car’s actual setup, including wheel compatibility, fender and steering clearance, and overall appearance. A car restored around wide whitewalls may also look different after the switch, so the construction decision should match both road-use expectations and visual goals.

Start with the basics: the 1958 Dodge Royal uses 800-14 and 850-14 bias-ply sizes on 14-inch rims, so the first step is verifying which size the car is actually set up to use. Once size is confirmed, the real selection factors become construction, sidewall style, brand, and the tire series available in that size.

Appearance matters on a car from this era, so blackwall, narrow whitewall, and wide whitewall choices can change the finished look significantly. It also helps to compare rim-width specifications, load figures where given, and whether you want a traditional bias-ply presentation or a carefully checked radial-equivalent alternative.

The available sidewall styles for 1958 Dodge Royal tires include blackwall, narrow whitewall, and wide whitewall. The broadest variety appears in 800-14, while 850-14 centers on narrow whitewall and wide whitewall options, giving owners a clear appearance choice within the correct period-style sizes.

Sidewall selection changes the personality of the car more than many buyers expect, especially on a full-size late-1950s Dodge. A blackwall creates a more restrained look, while whitewalls emphasize the era’s styling themes, so the right choice depends on the restoration direction and the size already matched to the wheels.

Tires for the 1958 Dodge Royal are available from BFGoodrich, Goodyear, and Universal Vintage Tire in the primary 800-14 and 850-14 fitment range. Depending on size, the available series include Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply.

Brand alone should not be the only deciding factor. It makes more sense to compare the available size, sidewall treatment, construction, and wheel-width suitability first, then narrow the choice by the series and presentation that best fit the car’s intended use and the way you want the Royal to look.

A period-style 1958 Dodge Royal usually starts with one of its primary bias-ply sizes, 800-14 or 850-14, depending on the wheel and tire setup already on the car. Staying with bias-ply construction preserves the vintage sizing format and keeps the tire choice aligned with the Royal’s late-1950s character.

After size is confirmed, appearance becomes the main decision. Wide whitewall and narrow whitewall options both suit the era well, but the final selection should reflect the specific restoration direction rather than assumptions about exact factory originality. For strict authenticity, marque-specific historical references are still worth checking.

Tire construction changes more than ride feel on a restored 1958 Dodge Royal; it also changes the visual character of the car. A bias-ply tire keeps the traditional vintage sizing format and complements the broad, upright tire presentation associated with many full-size American cars of the period.

A radial equivalent can be a useful alternative, but it may present the car differently depending on the exact size and sidewall chosen. Buyers who care as much about stance and visual balance as road manners should compare construction and sidewall treatment together instead of treating the change as a purely mechanical decision.

Yes, modifications can affect tire fitment on a 1958 Dodge Royal even when the tire size itself is correct. Changes such as aftermarket wheels, altered wheel width, suspension work, or ride-height changes can influence how an 800-14, 850-14, or a radial equivalent sits in the wheel opening.

A modified car should be checked for steering clearance, fender clearance, and wheel compatibility before new tires are chosen. Even two cars wearing the same badge can differ once wheels or suspension have been changed, so measuring the actual setup matters more than assuming a stock fitment is still in place.

Before driving a 1958 Dodge Royal on new tires, inspect the wheels for correct diameter and condition, make sure the tires are properly mounted and inflated, and look over the rest of the chassis for obvious issues that could affect road behavior. Lug hardware, wheel condition, and general suspension health deserve attention on any collector car.

A short, careful shakedown drive is the right next step after installation. Pay attention to steering response, clearance during turns, and any sign of rubbing or irregular movement, especially if the car has been fitted with a different size than before or has been off the road for a long period.

Collector-car tires on a 1958 Dodge Royal should be inspected regularly for air loss, tread wear, sidewall cracking, bulges, and cuts even if the car is driven only occasionally. Bias-ply tires in 800-14 or 850-14 sizing may spend long periods parked, which makes routine condition checks especially important.

Storage habits matter just as much as mileage on a low-use car. Keeping the Royal away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and periodic pressure checks before each outing make it easier to catch problems before they turn into road-use issues.
