900-14 Tire Size Guide

The 900-14 is a numeric bias-ply size. In that code, the 900 indicates a nominal section width of 9.0 inches, and the 14 identifies the wheel diameter in inches. It is a traditional inch-based sizing format used on classic passenger cars rather than a modern metric radial code.

Modern P-metric sizes include width in millimeters, an aspect ratio, and a construction letter, so they spell out more of the tire's proportions at a glance. The 900-14 does not print an aspect ratio in the code, which means buyers need to think of it as a period tire size whose overall profile is defined by the older sizing system. For restoration work, that older format matters because it helps preserve original sidewall height, stance, and visual balance.

The 900-14 fits a 14.0-inch wheel, which is 355.6 millimeters in diameter. The rim diameter must match exactly, so a 900-14 cannot be installed on a 13-inch or 15-inch wheel even if other dimensions seem close.

Wheel width matters too. In this size, the supported rim width range is 6.00 to 7.00 inches, which helps the tire hold the profile it was built to have. A wheel outside that range can change sidewall shape, alter clearance, and affect the way the car sits and steers. On a restoration, checking both wheel diameter and wheel width is just as important as matching the size printed on the sidewall.

The 900-14 has a nominal section width of 9.0 inches. Section width refers to the tire's widest point from sidewall to sidewall when inflated, not the width of the tread that contacts the road.

That distinction matters when you are checking fitment on a full-size classic car. Tread width is usually narrower than section width, but the sidewall bulge is what gets close to fenders, frame rails, steering parts, and suspension pieces. When buyers compare an original-size tire to a substitute, section width is one of the first numbers to evaluate because even a small increase can change clearance at full turn or during suspension movement.

Yes, 900-14 and 9.00-14 are two common ways of writing the same basic size. You may also see it written as 90014, 900 14, 900X14, or 9.00X14, depending on catalog style or how a manufacturer formats vintage tire sizes.

The important point is to read past the punctuation and confirm the underlying dimensions. In this case, the size still refers to a nominal 9.0-inch width on a 14-inch wheel. Vintage sizing is often written several different ways, so buyers should compare the full designation, construction type, and wheel requirements instead of assuming every similar-looking code represents a different fitment.

The 900-14 is commonly a tube-type fitment and is often set up with a tube. Tube use is still a wheel-and-tire-system question rather than a size question by itself, so the actual wheel and tire combination should be confirmed before installation.

Older wheels, restoration wheels, and certain tire constructions may call for a different tube decision than the size alone suggests. Buyers should inspect the wheel condition, verify whether the rim is intended for tubeless use, and follow the guidance for the specific tire being mounted. On collector cars, tube choice can affect air retention, service procedures, and reliability, so it is worth confirming before the tires go into service.

The 900-14 weighs 27 pounds per tire in the available fitments for this size. That figure refers to the tire by itself, without the wheel, tube, or mounting hardware.

Tire weight is not usually the first number a restoration buyer checks, but it still influences how the suspension responds and how much unsprung weight the car carries. On a large 1950s or 1960s passenger car, that weight works together with sidewall height, construction type, and wheel choice to shape ride quality and steering feel. It is most useful when comparing similar tires within the same original size rather than comparing across unrelated sizes.

The 900-14 was commonly used on large American passenger cars, especially full-size sedans, hardtops, convertibles, and wagons from the late 1950s into the mid-1960s. It appears on applications from Chrysler, De Soto, Lincoln, Mercury, and Oldsmobile, which places it firmly in the big-car, high-profile tire era.

Vehicle listings are a useful starting point, but they do not replace checking the car itself. Trim level, wheel choice, brake changes, and prior modifications can all affect what fits today. On a classic car, buyers should compare the existing tire size, confirm the 14-inch wheel diameter, verify the 6.00 to 7.00 inch wheel width range, and inspect clearance at the fender, steering, and suspension before treating 900-14 as the correct replacement.

Yes, the 900-14 is well suited to period-correct restoration work when the vehicle originally used this size and construction type. Its bias-ply construction aligns with the way many American passenger cars of the late 1950s and early 1960s were equipped, which helps preserve the original look and driving character.

Authenticity is more than the sidewall number alone, so buyers should still verify the original application before committing to a set. Wheel width, sidewall style, and the car's intended judging standard all matter. A correctly sized bias-ply tire can keep the proper wheel-opening fill and stance, while a substitute size or different construction may subtly change the appearance even if it still mounts on the same rim diameter.

The key wheel checks for the 900-14 are a 14-inch rim diameter and a 6.00 to 7.00 inch rim width. Those two measurements determine whether the tire can seat properly and hold the profile expected for this size.

Beyond those basics, inspect the wheel for condition, bead-seat integrity, and suitability for the way the tire will be used. A wheel that is too narrow or too wide can change sidewall shape and alter fender clearance, while an incorrect rim diameter prevents mounting entirely. On older cars, buyers should also confirm that wheel offset, brake upgrades, and suspension wear have not created interference that a factory-size tire would not originally have encountered.

The 900-14's bias-ply construction and tall vintage profile usually produce the kind of ride and steering character owners expect from a large 1950s or early 1960s car. The car may feel more traditional in its responses, with a softer sense of sidewall movement than drivers are used to from later radial tires.

Steering feel and comfort depend on more than size alone. Suspension condition, alignment, wheel width, inflation, and overall vehicle weight all influence how a classic car behaves on the road. On a well-sorted restoration, 900-14 tires tend to support an authentic driving experience, but buyers should remember that a period-correct feel is not the same thing as the more direct response many people associate with later radial-equipped vehicles.

A 900-14 bias-ply tire should be approached as a vintage design used in modern traffic, not as a modern touring tire. Drivers can expect an older-style road feel shaped by bias-ply construction, tall sidewalls, and the steering and suspension geometry of the vehicles that originally used this size.

Road behavior can vary significantly with alignment, tire age, wheel condition, and the mechanical state of the car. For that reason, owners should keep expectations realistic and make sure the vehicle is in sound operating condition before longer trips. Gentle break-in, regular pressure checks, and careful inspection all matter with a classic-size tire, especially on heavier passenger cars that place substantial demand on each corner.

When a car originally calls for 900-14, staying with that size is usually the best way to preserve its intended stance and wheel-opening fill. Vintage full-size cars were styled around tall tires, so the original-size profile plays a major role in how the body sits over the wheels.

Small changes in tire height or width can make a large car look noticeably different, even before they affect speedometer readings or clearance. A lower-profile substitute can leave more open space in the wheel well, while a wider or differently shaped tire may crowd the fender or alter steering clearance. For restoration-minded buyers, the visual effect is often just as important as the way the car drives.

BFGoodrich is available in the 900-14 size. In this case, the size is offered in classic bias-ply form with traditional whitewall choices aimed at vintage passenger-car use.

Brand selection is only one part of the decision. Buyers should also compare construction type, sidewall treatment, load rating, and whether the tire supports the look they want for the car. On a restoration, it is smart to keep the full set consistent so the vehicle has matching proportions and appearance at all four corners rather than mixing different visual styles or construction approaches.

A quality 900-14 tire starts with the right size accuracy, correct bias-ply construction, and a load rating appropriate for the vehicle. On large classic passenger cars, consistency in shape and profile matters because the tire strongly influences stance, steering feel, and the way the wheel opening is filled.

Construction quality should be judged in the context of the car's goals. A buyer focused on authenticity may prioritize a tire that preserves the original look and driving character, while another may focus on uniformity across the set and dependable service on occasional road use. It is also wise to compare wheel-width compatibility and confirm that every tire on the car matches in size, age range, and sidewall appearance.

The 900-14 is available with both wide whitewall and narrow whitewall styling. The better choice depends on the car's year, trim level, and the appearance you are trying to recreate rather than any difference in the basic size itself.

Whitewall width can noticeably change how formal or sporty a full-size classic looks, especially on late 1950s and early 1960s cars. Buyers aiming for originality should compare the tire to factory literature, surviving photos, or the car's trim history. If the goal is simply a coherent vintage look, the important thing is to run a matched set so the sidewall treatment remains visually consistent across the vehicle.

The 900-14 should be inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss, even if the tread still looks good. Bias-ply tires on collector cars can age from time, heat, sunlight, ozone exposure, and long periods of inactivity as much as from mileage.

Inspection should include the sidewalls, tread area, bead area, and valve hardware, along with a look at the wheel itself. A large classic passenger car places meaningful load on each tire, so condition matters as much as appearance. If there is any doubt about structural condition, especially on an older tire that has spent years parked, a qualified tire professional should evaluate it before the car returns to regular road use.

The 900-14 should be stored away from heat, direct sunlight, moisture, and ozone sources when a collector vehicle sits for extended periods. Clean, dry storage helps preserve the rubber and finish, and moving the vehicle occasionally can help reduce flat spotting during long layups.

Long-term care also includes keeping the car in a stable environment and checking the tires before the next driving season begins. Bias-ply tires may look serviceable from a distance while still developing age-related issues that only show up during a close inspection. Before returning the vehicle to road use, inspect the sidewalls, confirm air retention, and look over the wheels and valve components as part of the same routine.

The 900-14 is commonly a tube-type fitment, but tube use should still be confirmed from the actual tire and wheel combination. Wheel design, rim condition, and the specific tire being mounted all affect whether a tube is appropriate.

Older wheels deserve especially close attention because corrosion, damage, or design differences can change the air-retention picture. Buyers should inspect the rim carefully and follow the mounting guidance for the tire they are using rather than relying on size alone. Confirming tube use before installation can prevent service issues later and is a basic part of responsible fitment on vintage passenger-car wheels.

The 900-14 should be replaced when it shows cracking, bulges, exposed cord, repeated air loss, impact damage, or other visible signs of age and deterioration, even if tread depth still appears acceptable. Time and storage conditions can matter as much as mileage on a collector-car tire.

Replacement decisions should be based on both condition and intended use. A tire that may seem acceptable for display can be a poor choice for regular road driving or longer trips. Before using an older classic tire on public roads, inspect it closely and consider how much weight the vehicle carries, how fast it will be driven, and whether the wheel and valve components are in equally sound condition.

In this size, the available 900-14 tires are rated at 1,860 pounds at 32 psi. That figure applies per tire, so buyers should compare it to the actual weight requirements of the vehicle rather than assuming every large classic car uses the same load demand.

Load verification matters because the 900-14 was used on substantial full-size passenger cars, including wagons and premium models that can place more demand on the tire set. Check current sidewall markings, make sure all four tires match the vehicle's needs, and avoid mixing tires with different service capabilities on the same car. When in doubt, a qualified tire professional can help compare the tire's rating to the vehicle's real operating requirements.

Before driving on the 900-14, inspect overall tire condition, verify the 14-inch wheel diameter, confirm the 6.00 to 7.00 inch wheel width range, and make sure the tire and wheel are set up appropriately for tube use if required. A close pre-drive inspection is especially important on a vintage-size bias-ply tire.

Trip preparation should also include checking for uneven wear, reviewing air retention, and looking for any sign of wheel damage or bead-area trouble. On older vehicles, safe operation depends on the whole system working together, including suspension, steering, brakes, and wheels. Buyers should also confirm local road-use requirements and current sidewall markings rather than assuming a classic tire can simply be treated like a modern replacement.
