1967 Mercury Tires

The 1967 Mercury uses two primary tire sizes: 8.25-15 and 855-15. Both are bias-ply tire sizes for 15-inch wheels, and both apply to the covered group of models identified as all models except Comet, Cougar, and Wagon.

Choosing between those sizes starts with confirming what is already on the car and verifying the actual wheel dimensions. Many collector cars have seen wheel changes over the years, so the practical next step is checking the rim diameter, wheel width, and available clearance before selecting a new tire.

The primary tire fitments for the 1967 Mercury use a 15-inch rim diameter. Both 8.25-15 and 855-15 are built around that same 15-inch wheel size, which keeps the wheel-diameter question straightforward even though more than one tire size applies.

Rim diameter is only part of the fitment picture, so it helps to check wheel width as well before ordering tires. That becomes especially important if the car has aftermarket wheels or if you are considering an 855-15 radial equivalent, since construction changes can bring additional wheel-compatibility and clearance considerations.

On a 1967 Mercury, 855-15 is a vintage numeric bias-ply tire size. The 8.55 portion refers to the nominal section width in inches, while the 15 identifies the rim diameter, also in inches.

That older sizing format is different from modern metric radial sizing, so it often raises questions for owners returning a car to the road after many years. The important takeaway is that 855-15 is a traditional full-size Mercury fitment, and it also has named radial-equivalent alternatives that should still be checked carefully against the wheel and vehicle setup.

For the 1967 Mercury, 855-15 is a primary bias-ply tire size. In its original-format role on this vehicle, it is not a radial designation, even though radial-equivalent alternatives exist for owners considering a different construction.

That distinction matters because a bias-ply tire and a radial equivalent can change both appearance and setup considerations. Anyone moving away from the original bias-ply format should confirm wheel width, overall tire dimensions, and clearance at the fenders and suspension before assuming a radial alternative suits the car as currently configured.

Radial equivalents for 855-15 include 215R15 as the 80-series metric radial option, P225/75R15 as the P-metric 75-series radial option, P235/70R15 as the P-metric 70-series radial option, and 760R15 as the bias-look radial equivalent. Each one keeps the same basic 15-inch wheel diameter while using a different sizing convention.

Those options give you a range from conventional metric radial formats to a radial with a more traditional appearance. A 6-8 inch rim-width range is associated with the equivalent group, but wheel width, vehicle stance, and available clearance still need to be checked before making the change.

Start by confirming the exact original size on the car, the 15-inch wheel diameter, and the wheel width. For an 855-15 conversion, the available radial-equivalent choices include 215R15, P225/75R15, P235/70R15, and 760R15, with a 6-8 inch rim-width range tied to those alternatives.

A construction change should also be checked against steering clearance, fender clearance, suspension condition, and the car’s actual ride height. On a collector vehicle that may have aftermarket wheels or older suspension components, those physical checks are more useful than assuming every radial equivalent will behave the same way once mounted.

Choosing an 855-15 tire starts with keeping the correct vintage size and confirming that the car still uses a 15-inch wheel in the proper width range. In this size, the available products center on bias-ply construction, BFGoodrich branding, and narrow whitewall styling within the Silvertown Classic Bias Ply series.

The real choice is usually about appearance and intended use. A restoration-minded car may stay with a traditional bias-ply presentation, while a driver-focused car may lead you to compare the separate radial-equivalent options. Whitewall width, wheel compatibility, and the overall look of the finished car all matter here.

Among the currently available products for the 1967 Mercury, the visible sidewall treatment in 855-15 is narrow whitewall. That gives the car a distinctly period-style full-size American look without moving into wider whitewall territory that may create a different visual balance.

There are two narrow whitewall presentations in the available 855-15 offerings, so sidewall choice is part of the selection process even when brand and series remain the same. The best match depends on how formal, restrained, or restoration-oriented you want the finished car to appear once the tires are mounted.

The available 855-15 products for the 1967 Mercury are part of the BFGoodrich Silvertown Classic Bias Ply series. That series keeps the focus on a traditional bias-ply construction and period-style appearance rather than modern tread and sidewall presentation.

Series choice matters because it helps define the tire’s visual character and construction approach. In this case, the emphasis is on a classic full-size car look with narrow whitewall options, so the remaining decisions are mostly about whitewall width, wheel compatibility, and whether to stay with bias-ply or compare a radial-equivalent route.

A period-style 1967 Mercury typically starts with one of its original-format bias-ply sizes, either 8.25-15 or 855-15, depending on the car’s setup. For owners focusing on 855-15, the available BFGoodrich Silvertown Classic Bias Ply options keep that traditional construction and vintage visual character intact.

The best restoration-oriented choice depends on how closely the finished car is meant to reflect a specific historical presentation. When exact originality matters, compare the tire’s size and sidewall treatment with marque references, period photos, or other vehicle-specific documentation rather than relying only on general full-size Mercury styling cues.

Tire construction has a strong effect on the look of a restored 1967 Mercury because bias-ply tires present the car in a more traditional late-1960s full-size style. The primary fitments here are bias-ply, and that construction usually aligns more naturally with the visual proportions expected on a restoration-minded car.

A radial equivalent can still be considered, especially in 855-15, but it may change the overall presentation even when the wheel diameter stays the same. Owners balancing road use and appearance often compare a conventional metric radial with the 760R15 bias-look radial to keep a more vintage tire profile.

Yes, modifications can affect tire fitment on a 1967 Mercury even when the correct original tire size is known. Wheel changes, altered ride height, suspension work, or body modifications can all change how 8.25-15, 855-15, or an 855-15 radial equivalent sits within the car’s available space.

That is why the existing setup should be checked before choosing tires strictly by year and model. Measure wheel diameter and width, inspect clearance at full steering travel, and look at the relationship between the tire, fender opening, and suspension parts so the finished setup matches the car as it stands today.

Before driving a 1967 Mercury on new tires, inspect the wheels for correct diameter and sound condition, then confirm proper mounting and inflation. It also helps to check for suspension wear, alignment issues, and any signs that the car has been sitting long enough for other age-related problems to affect road manners.

A short driveway or neighborhood check is useful before a longer trip. Listen for rubbing, watch for steering pull or vibration, and recheck air pressure after the first few drives. On a collector-era full-size car, these simple checks help confirm that the tire choice and the vehicle setup are working together properly.

855-15 tires on a collector 1967 Mercury should be maintained with regular pressure checks, visual inspections, and attention to age even if tread wear is minimal. Collector cars often cover limited mileage, so sidewall cracking, flat-spotting from long storage, cuts, bulges, and slow air loss matter as much as tread depth.

Storage conditions also play a major role in tire life. Keeping the car away from prolonged sunlight, moisture, excess heat, and ozone sources helps preserve the tires between drives. Before road use, inspect each tire closely and pay extra attention to any changes in ride feel, steering response, or visible sidewall condition.
