1960 De Soto Tire Fitment Guide

1960 De Soto vehicles use two tire sizes: 800-14 and 850-14. Both sizes apply across all models in this year range, and both mount on 14-inch rims. Rim width support differs by size where published: 800-14 fits 5.00 to 6.00-inch rims, while 850-14 fits 5.50 to 6.00-inch rims.

That means year and make alone are not enough to choose between the two if you are aiming for a particular stance or restoration look. Start by confirming which size is on the car now, then verify the actual wheel width before moving to a product. Since both sizes are period-style bias-ply options, the main difference is the tire’s physical profile and the sidewall treatments available in each size.

On a 1960 De Soto, 800-14 is a numeric bias-ply tire size. The “800” refers to the tire’s nominal section width in the older numeric system, and the “14” identifies the wheel diameter in inches. It is not a modern metric radial code, so it should be understood as a vintage bias-ply sizing convention rather than translated directly into a modern P-metric size.

That matters because an 800-14 should be chosen as an original-style fitment, not as a generic modern 14-inch substitute. For 1960 De Soto applications, this size offers the widest visual variety, including blackwall, narrow whitewall, and wide whitewall versions. If your goal is a factory-era appearance, the code itself is part of that equation, since the tire’s profile and construction are tied to the way these cars originally sat and drove.

All 1960 De Soto models share the same two tire sizes: 800-14 and 850-14. There is no separate model-only fitment split within this year grouping, and both sizes are 14-inch bias-ply tires. That keeps the year-make fitment picture straightforward compared with other collector vehicles where different body styles or trims use entirely different wheel diameters.

Even so, the choice is still worth checking carefully because shared model fitment does not mean the two sizes are interchangeable in every visual or wheel-width situation. A car being restored to a very specific stance may favor one size over the other, and wheel width should still be matched to the tire. If you already know your car is a 1960 De Soto, the next step is confirming whether you want 800-14 or 850-14.

Both 800-14 and 850-14 are correct-style bias-ply sizes for 1960 De Soto vehicles, and both fit 14-inch wheels. The practical difference is that 850-14 is the larger of the two and carries a higher published load figure at 1740 lb at 32 psi, while 800-14 carries 1620 lb at 32 psi on BFGoodrich versions. Both preserve the original-era bias-ply construction and driving character rather than shifting the car toward a modern radial feel.

Choose between them by looking at the wheel width on the car and the look you want once the car is on the ground. The 800-14 works with 5.00 to 6.00-inch rims where published and gives you the broadest sidewall-style selection, including blackwall. The 850-14 fits 5.50 to 6.00-inch rims where published and often appeals to owners who want a fuller visual footprint on a big 1960 De Soto.

1960 De Soto tires are available in several period-appropriate sidewall styles, depending on size. The 800-14 comes in blackwall, narrow whitewall, and wide whitewall versions, while the 850-14 comes in narrow whitewall and wide whitewall versions. That gives owners room to tune the finished appearance from understated to more formal, full-size American-car styling.

For many 1960 De Soto restorations, whitewall choice is almost as important visually as tire size. A narrow whitewall can suit a cleaner late-1950s-to-1960 look, while a wide whitewall creates a stronger traditional luxury-car presentation. If your car is being judged, confirm the expected sidewall treatment with a De Soto marque specialist or period photos, because sidewall width can influence how authentic the finished car appears.

1960 De Soto tires are available from BFGoodrich and Universal Vintage Tire. BFGoodrich covers both 800-14 and 850-14, while Universal Vintage Tire appears in 800-14. Across those sizes, the offerings remain true to the era with bias-ply construction and whitewall-focused styling that suits a final-year De Soto restoration.

Brand choice often comes down to the exact combination of size and sidewall style you want. If you need 850-14, BFGoodrich is the brand represented in that size here. If you are considering 800-14, you have a broader mix of brand and sidewall options, including a blackwall route as well as whitewalls. Compare the brand selection only after you have settled on the correct size for the wheel and the appearance of the car.

1960 De Soto tire rim width depends on the size you choose. For 800-14, the published rim width range is 5.00 to 6.00 inches. For 850-14, the published rim width range is 5.50 to 6.00 inches. Both sizes fit 14-inch rims, but the acceptable wheel-width window is not identical.

That difference matters most if your car has replacement wheels, dealer-installed accessories, or wheels that may have been swapped over the decades. Measure the wheel before choosing between the two sizes rather than assuming any original-looking 14-inch wheel will suit both equally well. Confirming width first can keep the sidewall profile and mounting relationship consistent with what the tire was designed to do.

Inner-tube status is not the same as construction type, and a 1960 De Soto bias-ply tire should not automatically be assumed to require or not require a tube without checking the exact tire and wheel combination. The sizes here are bias-ply 14-inch tires, but tube use depends on the specific tire design and the wheel being used, especially if the wheels have age, pitting, or a profile that favors tube-type service.

The safest approach is to confirm the sidewall marking on the exact tire you choose and inspect the wheel condition before installation. Original steel wheels on collector cars can have rust scale, bead-seat wear, or old repairs that change the decision. If your installer finds the wheel does not support reliable tubeless operation, a tube may be part of the correct setup even when the tire itself is otherwise suitable for the car.

Original 1960 De Soto wheels can generally be used with both 800-14 and 850-14 because both sizes mount on 14-inch rims. The key point is wheel width, not wheel diameter. An 800-14 works with 5.00 to 6.00-inch rims where published, while an 850-14 calls for 5.50 to 6.00-inch rims where published.

That means a 14-inch wheel that is too narrow for 850-14 may still be suitable for 800-14. Before mounting either size, verify the actual wheel width and inspect the wheel for trueness, corrosion, and bead-seat condition. On a collector car like a 1960 De Soto, wheel originality does not automatically guarantee ideal service condition after decades of use, storage, or refinishing.

A 1960 De Soto should be stored away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that accelerate sidewall aging. Keep the floor dry, maintain proper inflation, and move the car periodically if possible so the tires do not sit in one loaded position for months at a time. Bias-ply tires are more prone to flat-spotting during long static storage than modern radials.

For winter or long-term layups, many owners either roll the car occasionally or support it in a way that reduces sustained load, depending on the suspension and storage plan. Tire covers can help when light exposure is unavoidable. The goal is to preserve the casing and sidewall finish so the car is ready to drive without vibration, visible weathering, or premature cracking when the season changes.

On a 1960 De Soto, tire age usually matters more than mileage because collector cars often see limited seasonal use. A practical rule is to begin evaluating older tires closely once they reach about five to seven years from date of manufacture, with replacement becoming a serious consideration as they approach ten years even if tread depth still looks serviceable. The DOT date code is the starting point for that age check.

Old bias-ply tires can look presentable long after the rubber has hardened and the casing has lost some of its original resilience. If the car spends long periods parked, the rubber may age out before the tread wears down in any meaningful way. Replacing on age rather than waiting for obvious tread wear is one of the best ways to keep a seldom-driven 1960 De Soto dependable on local and highway outings.

Tires on a 1960 De Soto should be inspected before every drive and again before any longer outing. Look for sidewall cracking, bulges, cuts, embedded objects, uneven tread wear, and signs that the tire has been run underinflated. On a collector car, also pay close attention to valve stems and the spare, since both may be older than they appear.

A quick walkaround catches many issues before they become roadside problems, especially on a heavy full-size car with vintage-style tires. Monthly pressure checks are a good habit even during storage, and a more thorough inspection should happen any time the car is put back into service after sitting. If the car develops new vibration or steering pull, stop assuming it is just old-car behavior and inspect the tires first.

A 1960 De Soto would have been fitted with bias-ply tires when new, which matches the construction used in the available 800-14 and 850-14 sizes. Both sizes fit the year’s 14-inch wheel applications covered here, and both preserve the original-era tire type rather than substituting a modern radial format. Original-equipment branding could vary by market and supply, so the key authenticity point is size, construction, and sidewall style.

For a restoration aiming at factory presentation, start with a bias-ply tire in the correct size and then narrow the choice by sidewall appearance. Whitewall width can have a major impact on whether the car looks authentically 1960 or merely vintage-inspired. If you are restoring to a specific trim, sales territory, or judging standard, consult De Soto club resources and period photography to confirm the most appropriate visual specification.

Correct tire fitment matters on a show-quality 1960 De Soto because judges and knowledgeable enthusiasts notice whether the tire looks appropriate for the car’s year and market position. Size, bias-ply construction, and sidewall style all affect authenticity. On a car from 1960, an obviously modern-looking replacement can change the profile of the car and make an otherwise careful restoration feel less faithful to the period.

That does not mean every event uses the same judging standard, but it does mean the tire should be treated as a visible restoration component rather than a generic maintenance item. A wide whitewall, narrow whitewall, or blackwall choice can shift the entire visual tone of the car. Before a serious concours build, confirm expectations with the event rules or a marque club so the final tire choice supports the way your De Soto will be evaluated.

For the 1960 De Soto, BFGoodrich appears in both 800-14 and 850-14, while Universal Vintage Tire appears in 800-14. In 800-14, BFGoodrich offers blackwall, narrow whitewall, and wide whitewall versions, with published load figures of 1620 lb at 32 psi on the BFGoodrich examples. Universal Vintage Tire adds a wide whitewall choice in the same 800-14 size, giving that fitment an additional period-style appearance option.

The practical distinction is less about one brand replacing another across the whole year and more about which size and sidewall combination you want for the car. If you need 850-14, your focus stays with BFGoodrich. If you prefer 800-14, you can compare brands partly through available styling, especially if the exact width and look of the whitewall are central to the restoration theme of your 1960 De Soto.

1960 De Soto tires in these sizes are bias-ply reproductions intended for road use within the limits of their construction, condition, and inflation. No speed ratings are published here for the 800-14 or 850-14 products, so highway use should be approached with the same judgment you would apply to any vintage full-size car: sound tires, correct pressure, and a realistic view of the car’s age, suspension design, and braking capability.

For most normal highway cruising, the broader mechanical condition of a 1960 De Soto often matters as much as the tires themselves. A bias-ply tire will feel different from a modern radial, especially in tracking and response, so the driver should allow for that character. Before regular highway use, confirm the tires are fresh, evenly worn, and mounted on sound wheels, then build speed only after the car proves stable and predictable.

For 1960 De Soto tires, the load-and-pressure figures published on these products are 1620 lb at 32 psi for 800-14 BFGoodrich examples and 1740 lb at 32 psi for 850-14 BFGoodrich examples. Those figures describe the tire’s rated load at that pressure, not automatically the pressure your specific car should always run. Factory vehicle recommendations can differ depending on weight distribution and intended use.

Use the original owner’s manual or factory service literature as your primary guide for vehicle pressure, then cross-check the tire manufacturer’s limits for the reproduction tire you choose. Do not move a pressure figure from 800-14 to 850-14 or vice versa simply because both fit the same year and make. Matching pressure to the exact size on the car is important for wear, steering feel, and overall stability.

Before a longer drive in a 1960 De Soto, inspect each tire for visible cracking, cuts, bulges, uneven wear, and any sign of air loss. Confirm cold pressure, check valve stems, and make sure the spare is usable and inflated. Because these are vintage-style bias-ply tires on an older full-size car, tire condition should be part of a broader mechanical inspection that also includes brakes, steering, cooling, and fluid levels.

A longer trip puts more heat cycles and continuous load into the tire than a short local outing, so small issues become more important. If the car has been sitting, drive it locally first to verify that there is no new vibration, pull, or pressure loss. Bringing the car back into regular service gradually is a smart way to confirm that both the tires and the rest of the chassis are ready for sustained road use.
