1958 De Soto LS 1 Tires

The 1958 De Soto LS 1 uses two primary tire sizes: 800-14 and 850-14. Both are bias-ply sizes for 14-inch rims, and the covered Wagon (9 Passenger) sub-model can use either size.

That makes confirmation especially important before replacement. The best starting point is the size already mounted on the car, followed by a check of the wheel diameter and width. If the wagon has been changed over the years, matching the replacement tire to the actual wheel and clearance setup matters more than assuming every LS 1 wagon still carries its original configuration.

The 1958 De Soto LS 1 uses a 14-inch rim with both of its primary tire sizes, 800-14 and 850-14. Even though the two tires differ in nominal width, they share the same rim diameter.

Rim diameter is only part of the fitment picture, so it helps to confirm wheel width before choosing a tire. Product specifications in these sizes show different rim-width allowances, which can influence which tire is the better match. On a collector wagon, that extra step also helps avoid clearance or appearance surprises if the wheels have been changed at some point.

The 1958 De Soto LS 1 is associated with both 800-14 and 850-14 bias-ply tires, even though both are built for 14-inch rims. The difference is primarily in nominal section width, with 850-14 representing a wider size within the same vintage sizing system.

That means the real question is not which number sounds closest, but which setup is actually on the wagon. Checking the sidewall of the current tire, the wheel dimensions, and the overall clearance around the fender and suspension gives a much better basis for replacement. Once the right size is confirmed, sidewall style and tire series become easier choices.

On the 1958 De Soto LS 1, 800-14 is a primary bias-ply tire size. It belongs to the vintage numeric bias-ply sizing system and is one of the two main fitments used on this model.

That matters because a bias-ply tire preserves the traditional profile and look many restoration-minded owners want. A radial alternative may still be considered, but it should be treated as an equivalent rather than the original construction type for this fitment. Before changing construction, confirm the wheel dimensions and make sure the wagon has adequate clearance for the chosen alternative.

For 800-14, radial equivalents include 205R14, P215/75R14, P225/70R14, and 800R14 as a bias-look radial. For 850-14, radial equivalents include 215R14, P225/75R14, and P235/70R14.

These options span several sizing formats, from an 80-series metric radial to 75-series and 70-series P-metric choices, with 800R14 offering a more traditional visual direction. Both primary sizes are associated with a recommended rim-width range of 5 to 7 inches for equivalent consideration. Wheel compatibility, actual section clearance, and overall tire dimensions should all be checked before making the change.

Start by matching the radial equivalent to the correct primary size, since the 1958 De Soto LS 1 uses either 800-14 or 850-14. Then confirm the 14-inch wheel diameter, make sure the rim width falls within the recommended range for the equivalent, and review the available clearance around the suspension and body.

Construction changes can also affect how the wagon sits and how the sidewall looks, so appearance goals matter as much as fitment. A buyer seeking a more traditional presentation may want to compare the bias-look radial against the standard metric and P-metric alternatives. Verifying the actual wheel setup on the car is especially important if it has seen wheel, brake, or suspension changes over time.

The first decision is confirming whether the wagon uses 800-14 or 850-14, since both sizes apply to the 1958 De Soto LS 1. From there, the main factors are construction type, wheel compatibility, sidewall appearance, and whether the goal is a traditional bias-ply presentation or a radial equivalent approach.

Available products add meaningful differences beyond size alone. In 800-14, there is broader variety in brands and sidewall styles, while 850-14 centers on BFGoodrich whitewall options. Comparing rim-width specifications, load figures where shown, and the visual character of blackwall versus whitewall treatments helps narrow the choice to something that suits both the wagon and the way it will be used.

The 1958 De Soto LS 1 has several sidewall styles available, depending on tire size. In 800-14, choices include blackwall, narrow whitewall, and wide whitewall, while 850-14 is offered in narrow whitewall and wide whitewall versions.

That gives the buyer room to shape the wagon’s overall presentation without changing the basic vintage tire format. A blackwall creates a more restrained look, while narrow and wide whitewalls move the car in different period-style directions. Since sidewall treatment can visually change the car as much as wheel covers or ride height, it is worth deciding early whether the goal is understated road use or a more restoration-oriented appearance.

Tires for the 1958 De Soto LS 1 are available from BFGoodrich, Goodyear, and Universal Vintage Tire. Brand choice varies by size, with 800-14 offering the broadest mix and 850-14 centered on BFGoodrich options.

Brand alone should not be the only filter. It helps to compare which tire series each brand offers, what sidewall treatments are available in the exact size you need, and whether the rim-width and load specifications align with the wheel and intended use. On a collector wagon, appearance often matters just as much as the name on the sidewall, especially when whitewall width is part of the decision.

A period-style 1958 De Soto LS 1 usually starts with one of its original-style bias-ply sizes, either 800-14 or 850-14, depending on the wagon’s actual setup. Staying with the correct vintage size family preserves the tall-sidewall look that suits a late-1950s De Soto.

The next decision is visual treatment rather than construction alone. Whitewall width changes the car’s character noticeably, and 800-14 offers blackwall, narrow whitewall, and wide whitewall choices, while 850-14 focuses on whitewall options. If exact originality matters beyond general period style, marque-specific restoration references and vehicle history should guide the final sidewall and brand selection.

Tire construction influences more than ride and handling on a restored 1958 De Soto LS 1. A bias-ply tire maintains the vintage sizing language and visual stance most closely associated with full-size late-1950s cars, while a radial equivalent can change the overall presentation even when it stays near the original size range.

That difference is especially noticeable on a wagon with a large body side and prominent wheel openings. Buyers who want a traditional restoration-oriented look often begin by evaluating the correct bias-ply size and matching sidewall style. Those considering radials should compare not just the numbers, but also how the tire’s profile and sidewall appearance support the look they want from the finished car.

Yes, modifications can affect tire fitment on a 1958 De Soto LS 1 even when the tire size itself falls within the correct vintage range. Changes to wheel width, wheel offset, ride height, brakes, or suspension parts can alter clearance at the fender, frame, or steering components.

That is especially important on a car that can use either 800-14 or 850-14. A wagon with aftermarket wheels or suspension changes should be measured rather than assumed to match an untouched factory-style setup. Looking at the current wheel dimensions and checking full-lock steering clearance provides a better fitment picture before choosing between the two primary sizes or a radial equivalent.

Before driving a 1958 De Soto LS 1 on new tires, inspect the wheels for damage or corrosion, confirm the lug hardware is in good condition, and make sure the tires are inflated appropriately for their application. It also helps to check for adequate clearance at the fenders, suspension, and steering through the full range of movement.

Collector cars often reveal other issues once fresh tires are installed. Worn steering parts, sagging springs, or old shocks can affect how the wagon tracks and how much space the tire really has under load. After the first few drives, recheck air pressure and look for any signs of rubbing, unusual wear, or air loss so small problems can be caught early.

Collector-car tires such as 800-14 or 850-14 on a 1958 De Soto LS 1 should be inspected regularly for cracking, cuts, bulges, uneven wear, and gradual air loss. Even a wagon that sees limited mileage can develop tire problems from age, storage conditions, or long periods of sitting.

Proper storage helps preserve both function and appearance. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can reduce sidewall aging, especially on whitewall tires that owners want to keep looking clean and even. Periodic pressure checks and occasional movement of the vehicle also help prevent flat spotting and make the next road outing more predictable.
