Mercury All Models Tires
Mercury All Models from 1957 through 1968 cover a period when the brand was positioned between Ford and Lincoln, blending full-size American comfort, substantial styling, and steadily evolving road manners. That matters when choosing tires, because Mercury fitment across these years was not static and the size changes reflect a real shift in wheel and tire practice during the era. The biggest complication in this range is that Mercury All Models move from 14-inch applications in the late 1950s and early 1960s to 15-inch applications later in the span, with some years also listing more than one size. Before selecting a tire, first confirm whether the car carries 14-inch or 15-inch wheels.
Mercury All Models Tire Size Guide
Mercury All Models use 7 distinct tire sizes across the 1957 to 1968 production span, and the most important fitment change is the move from 14-inch to 15-inch wheels beginning in 1966. Earlier sizes in this range use 14-inch rims, while later sizes use 15-inch rims, so wheel diameter is the first thing to verify on the actual car. These sizes are classic numeric bias-ply designations, where the first number represents nominal section width and the last number is the rim diameter in inches.
850-14 is a 1957 Mercury All Models size used on 14-inch applications from the earliest year in this range. The 850 portion is the nominal section width with the decimal omitted, and the 14 indicates a 14-inch rim diameter; available products fit 14-inch rims with 5.50 to 6.00 inch rim widths. Choose this size for a 1957 Mercury All Models that still uses its correct 14-inch wheel setup, and because the available products are bias-ply, a tube is required.
750-14 is one of the two sizes listed for 1961 Mercury All Models and fits 14-inch wheel applications for that year. The 750 portion is the nominal section width with the decimal omitted, and the 14 indicates a 14-inch rim diameter; available products are built for 14-inch rims with most listings calling for 5.00 to 5.50 inch rim widths. Choose this size only after confirming the specific 1961 Mercury All Models configuration, and because the available products are bias-ply, a tube is required.
800-14 appears on Mercury All Models in 1961 and again in 1964, both on 14-inch wheel applications. The 800 portion is the nominal section width with the decimal omitted, and the 14 indicates a 14-inch rim diameter; available products fit 14-inch rims with typical rim width guidance around 5.00 to 6.00 inches. Choose this size for a 1961 or 1964 Mercury All Models after checking the actual wheel and original specification for that car, and because the available products are bias-ply, a tube is required.
8.45-15 is one of the sizes listed for 1966 Mercury All Models and marks the move to 15-inch wheel fitment in this range. The 8.45 portion is the nominal section width in inches, and the 15 indicates a 15-inch rim diameter. Choose this size only on a 1966 Mercury All Models already confirmed to use the 15-inch setup, keeping in mind that product availability is not shown here for this specific size.
815-15 is the other size listed for 1966 Mercury All Models and fits 15-inch wheel applications from that year. The 815 portion is the nominal section width with the decimal omitted, and the 15 indicates a 15-inch rim diameter; available products fit 15-inch rims with 5.00 to 6.50 inch rim widths. Choose this size after verifying which 1966 Mercury All Models configuration you have, and because the available products are bias-ply, a tube is required.
8.25-15 is one of the two sizes listed for 1968 Mercury All Models and belongs to the later 15-inch wheel period. The 8.25 portion is the nominal section width in inches, and the 15 indicates a 15-inch rim diameter. Choose this size only after confirming the exact 1968 Mercury All Models wheel and factory-type specification, as product availability is not shown here for this specific size.
855-15 is the second size listed for 1968 Mercury All Models and fits 15-inch wheel applications. The 855 portion is the nominal section width with the decimal omitted, and the 15 indicates a 15-inch rim diameter; available products fit 15-inch rims with 6.00 to 6.50 inch rim widths. Choose this size only after confirming which 1968 Mercury All Models configuration you are matching, and because the available products are bias-ply, a tube is required.
Mercury All Models Tires by Year
The year listing below shows which tire sizes are associated with each Mercury All Models year so you can narrow the choices before comparing products. Mercury All Models production changed from 14-inch to 15-inch wheels in 1966, so confirm which rim diameter the specific car carries before selecting a tire. In 1961, 1966, and 1968, more than one size is listed, which points to configuration differences within those model years.

Frequently Asked Questions
The questions below focus on the fitment issues that matter most for Mercury All Models, especially the shift from 14-inch to 15-inch wheels and the year-to-year size differences within this 1957 to 1968 range.
Size Basics & Fitment
Mercury All Models in this range use 850-14 for 1957, 750-14 and 800-14 for 1961, 800-14 for 1964, 8.45-15 and 815-15 for 1966, and 8.25-15 and 855-15 for 1968. The 1957, 1961, and 1964 sizes are 14-inch rim applications, while the 1966 and 1968 sizes are 15-inch rim applications. Available products are shown for 850-14, 750-14, 800-14, 815-15, and 855-15, all in bias-ply construction.
Start with the model year, then confirm the actual wheel diameter on the car before narrowing the choice further. Where a single year shows two sizes, the correct tire depends on the specific Mercury All Models configuration rather than the year alone. If the car has been restored or modified over time, wheel measurements and original service information are more reliable than assumptions based only on appearance.
On Mercury All Models, 850-14 is a classic numeric bias-ply size. The 850 indicates nominal section width with the decimal omitted, and the 14 indicates the tire fits a 14-inch wheel. The available 850-14 products in this range are bias-ply tires built for 14-inch rims, with listed rim widths of 5.50 to 6.00 inches.
That decoding matters because a modern buyer may see an older numeric size and focus only on the last number. On a Mercury All Models, the wheel diameter is still critical, but the first number also affects stance and proportions. If you are matching a 1957 car for period appearance, confirm both the 14-inch wheel and the appropriate rim width before choosing between the available sidewall styles.
A 1961 Mercury All Models can show both 750-14 and 800-14 because more than one configuration used 14-inch tires that year. The split is not a wheel-diameter change, since both sizes use 14-inch rims, but rather a difference within the model range. That means the year alone is not enough to identify the correct tire.
Use the existing wheel size, original placard information, factory literature, or restoration records to determine which of the two widths belongs on your Mercury All Models. Buyers restoring a car to original appearance should also consider the stance they are trying to preserve, since 750-14 and 800-14 can affect the visual fullness of the wheel opening even when both fit 14-inch wheels.
Mercury All Models in this range use two rim diameters: 14-inch wheels in 1957, 1961, and 1964, and 15-inch wheels in 1966 and 1968. The change to 15-inch applications begins in 1966. Individual sizes confirm that split clearly, with 850-14, 750-14, and 800-14 on 14-inch rims and later sizes such as 815-15 and 855-15 on 15-inch rims.
That rim-diameter break is the first thing to verify on any Mercury All Models, especially on a car that may have had wheels changed during restoration or long-term ownership. Measure the wheel or read the existing tire size before choosing anything else. Once the rim diameter is confirmed, you can sort out the correct section width and sidewall style for the year and configuration.
Buying the Right Tire
A 1966 Mercury All Models can use either 8.45-15 or 815-15, and both are 15-inch applications. That means the correct choice depends on the specific configuration rather than the year alone. Among the listed products, 815-15 has available bias-ply options for 15-inch rims with 5.00 to 6.50 inch rim widths.
Begin by confirming that the car still carries 15-inch wheels, then compare the current tire markings, wheel width, and any original reference material that came with the car. If the car is being restored, judge the size against the intended stance and originality level. A Mercury All Models with replacement wheels or mixed components can easily end up wearing a size that fits physically but is not the correct period specification.
Mercury All Models tires in the listed sizes are available in several period-style sidewall treatments, including blackwall, narrow whitewall, wide whitewall, redline, and whitewall-redline. The broadest variety appears in 750-14, while 800-14 also offers blackwall and whitewall choices. Later 15-inch sizes such as 815-15 and 855-15 show narrower whitewall-oriented options, including a whitewall-redline version in 815-15.
The right sidewall style depends on whether your Mercury All Models is being restored to factory-type appearance, personalized in period style, or prepared for local judging. A large late-1950s American car often looks quite different on a wide whitewall than on a blackwall or redline. Match the sidewall treatment to the car's year, trim character, and restoration goal rather than choosing only by visual preference.
The listed Mercury All Models products come from BFGoodrich, US Royal, Coker Classic, Firestone, Universal Vintage Tire, and Goodyear. Brand coverage varies by size, with the strongest selection appearing in 750-14 and 800-14. Later 15-inch sizes shown here are more concentrated, especially in BFGoodrich offerings.
Brand choice on a Mercury All Models often comes down to how closely you want to match a period-correct look, sidewall treatment, and series style for the year you are restoring. If originality matters, compare the available brands alongside the sidewall design and overall visual profile. If practical road use matters most, confirm that the brand you choose is offered in the exact size and rim width range your car requires.
Mercury All Models products in this range appear in several series, including Silvertown Classic Bias Ply, US Royal Classic Bias Ply, Coker Classic Bias Ply, Firestone Classic Bias Ply, Universal Classic Bias Ply, and Goodyear Custom Super Cushion. These are all bias-ply offerings rather than a mix of bias-ply and radial constructions. The main differences shown here are brand identity, period-style presentation, and sidewall treatment rather than a change in basic construction type.
For a Mercury All Models owner, the practical choice is less about modern performance categories and more about visual authenticity, era-correct character, and which series offers the sidewall style that suits the car. A car headed for show presentation may call for a different series choice than one meant for weekend driving. Once the correct size is established, compare series by appearance and by how closely they match the look you want.
Maintenance & Longevity
A stored Mercury All Models should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, ozone sources, and petroleum contamination. Tires on a collector car age more from time and environment than from mileage alone, and the large, load-bearing bias-ply tires used on these Mercury applications benefit from stable storage conditions. Clean floors, proper inflation, and protection from prolonged moisture all matter.
If the Mercury All Models will sit for long periods, move it periodically so the same part of each tire is not supporting the car month after month. Many owners also reduce stress by using tire cradles or taking some load off the suspension during extended indoor storage. Storage habits directly affect ride quality, sidewall appearance, and how well the tires hold their shape over time.
Tires on a Mercury All Models should be inspected before every meaningful drive and more thoroughly at regular intervals during the season. On a bias-ply collector tire, the inspection should include inflation pressure, sidewall cracking, bulges, tread separation signs, valve condition, and any uneven wear pattern. Cars that sit for long periods deserve even closer attention because aging can progress without accumulating mileage.
A quick visual check is not enough for a heavy classic Mercury All Models. Look closely at both sidewalls, inspect the tread all the way around, and pay attention to how the car feels when it first starts rolling. Any new vibration, pull, or change in steering feel is a reason to stop and inspect the tire and wheel assembly before continuing.
Mercury All Models tires should be replaced when age, cracking, hardening, impact damage, separation signs, or long-term storage deterioration make them questionable, even if the tread still looks deep. Collector tires often age out before they wear out. That is especially true on bias-ply applications, where a tire can look serviceable at a glance yet no longer be suitable for road use.
Treat tread depth as only one part of the decision. If a Mercury All Models has been parked for years, recently revived, or driven infrequently, have the tires evaluated as part of the recommissioning process. Replacement timing should reflect age and condition first, because a large vintage car places real load on its tires and can quickly expose hidden weaknesses.
Restoration & Authenticity
Mercury All Models in this 1957 to 1968 span show several original-type size patterns rather than one universal tire specification. The listed sizes include 850-14, 750-14, 800-14, 8.45-15, 815-15, 8.25-15, and 855-15, with classic bias-ply series from multiple brands. That reflects how Mercury fitment changed across the period and why a single answer for every year is not accurate.
For an accurate restoration, match the tire size first to the exact year and then to the specific configuration of your Mercury All Models. The next step is choosing a sidewall treatment and series that suit the car's original presentation. Factory literature, period photos, and marque-club references are the best way to narrow a specific car beyond the broader year-and-size range.
Correct tire fitment can materially affect both presentation and judging on a Mercury All Models because tire diameter, width, and sidewall style all shape the car's stance. A late-1950s or 1960s full-size American car can look notably different when the whitewall width or overall section width is off. Judges and knowledgeable buyers often notice tire details immediately because they are so visible.
If the goal is restoration value, match the Mercury All Models tire size to the proper year and wheel diameter first, then choose the sidewall style that fits the car's intended period look. A blackwall, narrow whitewall, or wide whitewall can each be appropriate in the right context. Marque clubs and surviving original cars are useful references when a concours-level presentation matters.
Mercury All Models tires in the listed range are offered with blackwall, narrow whitewall, wide whitewall, redline, and whitewall-redline styling depending on size. The earliest late-1950s applications in this group naturally align with broader whitewall-era styling, while later 1960s cars may suit narrower whitewalls or sportier sidewall treatments where available. The correct answer depends on the specific year and the visual character you are trying to restore.
Choose the sidewall style that matches the car's period presentation before focusing on brand preference. A 1957 Mercury All Models can look most at home with a stronger whitewall presence, while a later car may call for a more restrained look. If you are restoring to judged standards, compare your choice against period photography and the trim level of the car rather than selecting by taste alone.
Safety & Road Use
The listed Mercury All Models tires are purpose-built vintage-style bias-ply tires, and they can be suitable for public-road use when they are the correct size, properly mounted on the correct wheel, inflated correctly, and in sound condition. Safety starts with using the proper 14-inch or 15-inch fitment for the specific car. A wrong wheel diameter or mismatched size is a more immediate problem than brand choice.
A Mercury All Models owner should also remember that a classic bias-ply tire drives differently from a modern radial-equipped car. Steering response, tracking, and braking feel reflect the period design of both the tire and the vehicle. Keep expectations realistic, inspect the tires regularly, and treat road use as part of the overall condition of the car rather than as an isolated tire decision.
Before driving a Mercury All Models, check tire pressure, visible sidewall condition, tread condition, wheel security, and any sign of age-related cracking or separation. Confirm that all four tires are the same size and construction type that belongs on the car, especially if the vehicle has changed hands or been stored for years. Also confirm that the wheel diameter matches the installed tire size, since this range includes both 14-inch and 15-inch applications.
The first few miles should be treated as an active inspection period. Listen for thumps, feel for pull or shimmy, and stop if anything changes noticeably. On a large classic Mercury All Models, minor tire issues can become major drivability problems quickly, so a deliberate pre-drive routine is one of the simplest ways to protect both the car and the people riding in it.
A Mercury All Models running vintage-style bias-ply tires should be driven at sensible speeds that match the age, setup, and mechanical condition of the car, even when the tires are new reproductions. These cars were designed in a different handling era, and bias-ply behavior is part of that experience. Straight-line cruising, steering correction, and stopping distances all deserve more margin than a modern vehicle would require.
The practical approach is to build speed gradually and let the car tell you what feels stable and composed. Freshly restored cars, long-stored cars, and cars wearing newly installed tires should be road-tested conservatively at first. A Mercury All Models in excellent mechanical condition may be comfortable at moderate road speeds, but spirited driving should never outrun the limits of the tire, chassis, and braking system.
