Mercury Convertible & Wagon Tires

Mercury Convertible & Wagon uses two listed tire sizes for 1958: 800-14 and 850-14. Both sizes fit 14-inch wheels, but they are not the same overall section size. The 800-14 products are shown on 14-inch rims with common rim widths of 5.00 to 6.00 inches, while the 850-14 products are shown on 14-inch rims with common rim widths of 5.50 to 6.00 inches. All available products in these sizes are bias-ply tires.

That means the first step is not identifying the year alone, but confirming which of the two sizes belongs on the specific Mercury Convertible & Wagon in your garage. Check the size currently mounted, measure the wheel width, and compare against original paperwork if the car has been restored or modified over time. Getting the right section size matters for stance, steering feel, and period-correct appearance.

On a Mercury Convertible & Wagon, 800-14 is a late-1950s numeric bias-ply size. The 800 indicates a nominal 8.00-inch section width, and the 14 indicates the wheel diameter in inches. The products offered in this size are all built for 14-inch rims, and the listed rim width range commonly runs from 5.00 to 6.00 inches. This is a traditional bias-ply sizing system rather than a modern metric radial code.

For a buyer, that means 800-14 should be matched to both the wheel diameter and the wheel width actually on the car. It is also worth deciding whether you want a blackwall, narrow whitewall, or wide whitewall presentation, since all three visual styles appear in the available 800-14 offerings. If the car’s wheel width falls outside the listed range, recheck the wheel before moving ahead.

A 1958 Mercury Convertible & Wagon can show 800-14 and 850-14 because the fitment split is by tire size rather than by wheel diameter. Both sizes use 14-inch rims, but the 850-14 is the larger nominal section width. The available products remain bias-ply in both cases, so the difference is not radial versus crossply construction. This kind of same-year split is typical on full-size American cars when body style, load expectation, or original equipment variation affects the specified size.

The practical takeaway is that year alone does not settle the answer for every 1958 Mercury Convertible & Wagon. Look at the wheel width, inspect any original decals or paperwork that survived with the car, and compare the proportions of the existing tires if the car has an established restoration history. If the car is being judged, matching the exact size and sidewall style to the intended presentation matters.

Mercury Convertible & Wagon tire options in 800-14 and 850-14 are bias-ply products, and a tube is required. That applies across the listed offerings, whether the tire is blackwall, narrow whitewall, or wide whitewall. The need for a tube follows the construction type and period-style fitment rather than the visible sidewall treatment. Both listed sizes are traditional collector-car bias-ply applications rather than modern tubeless metric radials.

When replacing tires on a Mercury Convertible & Wagon, plan the tube choice as part of the job instead of treating it as an afterthought. Tube condition matters just as much as the outer casing on a low-use collector car, especially if the car has been sitting for long periods. It is also wise to inspect the wheel interior and valve hole condition before mounting fresh tires, since rust, burrs, or old rim strip issues can shorten tube life.

A 1958 Mercury Convertible & Wagon can use either 800-14 or 850-14, so the correct size needs to be confirmed on the individual car. Both fit 14-inch wheels, but they differ in nominal section width and in the rim width ranges shown with the available products. The 800-14 offerings commonly suit 5.00 to 6.00-inch rims, while the 850-14 offerings commonly suit 5.50 to 6.00-inch rims. That makes wheel width an important clue when the car’s current tires are questionable.

Start by reading the size on the tire now fitted, then verify the wheel diameter and width directly on the car. If the Mercury Convertible & Wagon has been restored, lowered, or otherwise altered, compare what you find against factory literature, build records, or marque-club guidance. A little time spent confirming the actual wheel and tire package helps avoid choosing a size that changes the car’s look or fit unnecessarily.

Mercury Convertible & Wagon tires in the listed sizes are available in blackwall, narrow whitewall, and wide whitewall versions. The 800-14 size offers all three looks, while the 850-14 size is shown in narrow whitewall and wide whitewall form. Those choices matter because late-1950s American cars often look noticeably different depending on whitewall width. The sidewall treatment changes the appearance of the car even when the underlying size remains the same.

If your Mercury Convertible & Wagon is being restored to a specific presentation, match the sidewall style to the trim level, restoration goal, and period image you want the car to project. Wide whitewalls give a stronger late-1950s visual statement, while narrow whitewalls and blackwalls can create a more restrained look. Use period photos, surviving dealer literature, or club references if originality is part of the goal.

Mercury Convertible & Wagon tires in the listed 1958 sizes are available from BFGoodrich, Universal Vintage Tire, and Goodyear. BFGoodrich appears in both 800-14 and 850-14, Universal Vintage Tire appears in 800-14, and Goodyear appears in 800-14. The available series include Silvertown Classic Bias Ply, Universal Classic Bias Ply, and Custom Super Cushion. All of them stay within period-style bias-ply construction for this application.

Brand choice usually comes down to the combination of size availability, preferred sidewall style, and the visual character you want on the finished car. Some owners prioritize a broad selection of whitewall widths, while others are focused on matching a familiar period look. Once the size is confirmed, comparing brand and series options is the next logical step rather than the first.

Mercury Convertible & Wagon tire options appear in three series: Silvertown Classic Bias Ply, Universal Classic Bias Ply, and Custom Super Cushion. All three are bias-ply offerings, so the major differences here are not radial versus bias construction but brand family, sidewall presentation, and size coverage. Silvertown Classic Bias Ply appears in both 800-14 and 850-14, Universal Classic Bias Ply appears in 800-14, and Custom Super Cushion appears in 800-14. Each keeps the period-style bias-ply format expected for a 1958 application.

For a restorer or driver, the practical choice is to settle the correct size first and then compare which series gives the sidewall treatment and brand identity that best fits the car. A Mercury Convertible & Wagon restored for period presence may lean toward a whitewall-heavy look, while a more understated car may suit blackwalls or narrow whites. The series name helps separate those visual and brand choices once fitment is already confirmed.

A Mercury Convertible & Wagon should be stored on a clean, dry surface away from direct sunlight, ozone sources, and wide temperature swings. Tires on collector cars last longer when they are kept away from electric motors, welders, furnaces, and other equipment that can age rubber prematurely. Inflation should be checked before storage so the car is not left sitting low on one corner. Long static periods are especially hard on bias-ply tires because they can develop flat-spotting and casing stress.

If the Mercury Convertible & Wagon will sit for weeks or months, roll it periodically or use methods that reduce concentrated load on one contact patch. Keep the tires clean with mild soap and water only, and avoid shiny dressings that can dry the rubber over time. A simple storage routine goes a long way toward preserving ride quality and appearance on a car that is driven infrequently.

Tires on a Mercury Convertible & Wagon should be inspected before each drive and more thoroughly at regular intervals during the season. Check inflation, sidewall condition, tread surface, valve stems, and any sign of cracking, bulging, or impact damage. Because the listed tires are bias-ply designs, they can also show changes in shape or wear pattern that are easier to catch early with routine inspection. Collector cars often age their tires by time and storage conditions rather than mileage alone.

A practical habit is to walk around the Mercury Convertible & Wagon before every outing and then perform a closer inspection several times each year, especially after winter storage. If the car has been parked for a long time, inspect the tube-equipped assemblies carefully before returning it to road use. Regular checks help you catch small problems before they become vibration, poor tracking, or a roadside issue.

Tires on a Mercury Convertible & Wagon should be replaced when age, cracking, hardening, casing distortion, or repeated air-loss issues appear, even if the tread still looks usable. Collector-car tires often spend more time aging than wearing, so visible tread depth alone is not a reliable measure of service life. Bias-ply tires especially deserve attention if the car has been stored for long periods, run underinflated, or driven little for many years. Tube condition should be considered at the same time, since tube problems can mirror or compound tire problems.

The best approach is to treat replacement as a condition-based decision supported by regular inspection rather than waiting for the tread to disappear. If the Mercury Convertible & Wagon develops ride harshness, persistent flat-spotting, sidewall checking, or unexplained vibration, it is time for closer evaluation. Collector-car use rewards caution, and replacing aged tires before they fail is far cheaper than repairing body or chassis damage caused by a preventable tire problem.

Mercury Convertible & Wagon is shown with two period-style 1958 fitment sizes: 800-14 and 850-14, both in bias-ply construction. The available replacement lines include Silvertown Classic Bias Ply, Universal Classic Bias Ply, and Custom Super Cushion, which reflect the kind of bias-ply format expected for the era. Because more than one size appears within the same model year, original fitment can vary by the specific car. That means there is not a single universal answer that covers every 1958 Mercury Convertible & Wagon.

For an accurate restoration, use the car’s surviving paperwork, period photos, and marque-club references to determine whether 800-14 or 850-14 is the better match. The correct sidewall treatment matters too, since blackwall, narrow whitewall, and wide whitewall options can change the finished look considerably. Authenticity is usually the product of getting size, construction, and appearance right together rather than choosing any one element in isolation.

Correct tire fitment can absolutely affect how a Mercury Convertible & Wagon is perceived in restoration judging and, in many cases, how it presents to knowledgeable buyers. Size, construction type, and sidewall style all contribute to whether the car looks faithful to its period. On a late-1950s American car, the difference between blackwall, narrow whitewall, and wide whitewall can be visually dramatic. Using the wrong size can also alter the stance and wheel opening fill in ways experienced judges and collectors notice quickly.

If the goal is top-tier authenticity, treat tire selection as part of the restoration plan rather than a finishing detail. A Mercury Convertible & Wagon aimed at formal judging should be checked against marque standards and period references before the final choice is made. Even on a driver-level car, correct fitment supports a more convincing, better-balanced result and can help preserve the vehicle’s collector appeal.

Mercury Convertible & Wagon tire offerings include blackwall, narrow whitewall, and wide whitewall styles, so the correct choice depends on the restoration goal for the specific car. Wide whitewalls are strongly associated with the visual language of many late-1950s American cars, while narrow whitewalls and blackwalls can suit a different trim presentation or owner preference. The 800-14 size has all three looks available, and the 850-14 size is available in narrow and wide whitewall form. Sidewall style is therefore a meaningful authenticity choice, not just a cosmetic afterthought.

To decide what belongs on a Mercury Convertible & Wagon, compare the car against period photography, showroom literature, and club guidance for the way you want the finished restoration judged or displayed. A car restored for maximum late-1950s presence may call for wide whitewalls, while a more restrained build might lean elsewhere. Make that decision after the correct size is settled so the look and fit work together.

Yes, properly selected and properly maintained bias-ply tires can be used for public-road driving in a Mercury Convertible & Wagon, provided the car itself is mechanically sound and the tires are in healthy condition. The listed sizes for this application are traditional collector-car bias-ply designs, so they should be treated as period-style equipment rather than modern high-speed touring tires. Safe use depends on correct size selection, sound tubes, proper inflation, and the overall condition of the chassis, brakes, steering, and suspension.

That means a Mercury Convertible & Wagon should be driven within the limits of its design and setup, not like a modern sedan on contemporary radial tires. Before putting real road miles on the car, inspect the tires carefully and make sure the vehicle tracks, steers, and brakes properly. A well-sorted collector car on the right tires can be enjoyable on public roads, but it still rewards measured use and regular inspection.

Before driving a Mercury Convertible & Wagon, check tire inflation, visible sidewall condition, tread surface, valve stems, and the general security of the wheel and tire assembly. Because the listed fitments are bias-ply tube-type applications, it is also wise to watch for slow air loss or changes in shape after the car has been sitting. A quick look underneath for suspension or brake issues is just as important, since tire performance can be affected by the condition of the rest of the car. Any pulling, vibration, or unusual wear deserves attention before the next outing.

The practical routine is simple: inspect the tires cold, look for cracking or bulges, and make sure the car sits evenly before leaving the garage. If the Mercury Convertible & Wagon has been stored for an extended period, take the first drive gently and pay attention to steering feel and ride behavior as the tires come back into use. Small checks before departure prevent many of the problems that strand seldom-driven collector cars.

A Mercury Convertible & Wagon fitted with period-style bias-ply tires should be driven at moderate, sensible speeds that respect both the tire design and the age of the car’s chassis systems. These tires are built to preserve the correct look and driving character of a 1958 application, not to duplicate the behavior of a modern performance radial. Road conditions, temperature, inflation, loading, and the condition of the suspension and brakes all influence what is appropriate. Smooth, steady touring is the right mindset.

In practical terms, drive the Mercury Convertible & Wagon in a way that leaves generous braking distance and avoids abrupt lane changes, hard cornering, or sustained high-speed cruising. Bias-ply tires can follow road grooves and feel different from modern tires even when everything is working properly. If the car is newly restored or newly fitted with tires, build confidence gradually and let the car tell you how settled and stable it feels.
