1955 Chevrolet Tire Fitment Guide

All six 1955 Chevrolet models covered here use the same tire size: 670-15. That includes the 1500, 2100, 2400, Bel-Aire, Corvette, and Wagon. The available products in this size are bias-ply tires built for 15-inch rims, and the listed rim-width ranges run from 4.50 to 5.00 inches on some products and 5.00 to 6.00 inches on others.

That shared fitment makes year-and-make research easier, but you should still confirm the actual wheel on the car before choosing a tire. A restored sedan, a dressed-up Bel Air, and a Corvette may all use the same 670-15 size, yet the wheel width and the appearance you want can influence which specific product makes the most sense. Matching the tire to the wheel and the car's intended presentation is the final step.

On a 1955 Chevrolet, 670-15 is a numeric bias-ply tire size. The 6.70 refers to the nominal section width in inches, while the 15 identifies the wheel diameter in inches. Because there is no radial construction marker in the size itself, this format belongs to the mid-century bias-ply era rather than a later radial sizing system.

That matters because a 670-15 should be understood as a period-style fitment, not a modern metric equivalent written in another way. Buyers comparing products in this size should focus on the wheel diameter, the product's stated rim-width range, and the sidewall appearance they want on the finished car. Once those three points line up, choosing among brands becomes much more straightforward.

Yes. The 1955 Chevrolet 1500, 2100, 2400, Bel-Aire, Corvette, and Wagon all use 670-15 in the fitment covered here. That means Chevrolet's model differences for this year do not create separate tire-size paths within this group, even though the cars themselves occupied different positions in the lineup.

For a buyer, that removes one common source of confusion: you do not need to sort through multiple listed sizes before narrowing down a product. Instead, your model choice mainly affects the visual direction of the tire, especially if you are trying to match a base-trim, upscale, sporty, or family-car appearance. The size stays the same; the presentation and restoration priorities can change.

1955 Chevrolet tires in 670-15 are available in both blackwall and wide whitewall styles. Firestone and Universal Vintage Tire are represented in blackwall form, while US Royal and Coker Classic are represented with wide whitewalls in this size. All of them remain bias-ply constructions, so the visual difference comes from sidewall treatment rather than a shift to a different tire type.

That choice has a strong effect on the finished look of a 1955 Chevrolet. Blackwalls suit a plainer, more understated presentation and can feel right on lower-trim or more driver-oriented cars, while wide whitewalls reinforce the bright, dressier mid-1950s look many owners want on Bel Airs and other show-focused builds. If authenticity matters for judging, compare your sidewall choice to period photos and marque-club guidance.

Four brands are represented for 1955 Chevrolet vehicles in 670-15: Firestone, US Royal, Coker Classic, and Universal Vintage Tire. Each offering is a bias-ply tire for a 15-inch rim, but the sidewall presentation differs by product, with blackwall and wide whitewall options both available in the size.

Brand choice on a collector Chevrolet often comes down to the balance between visual authenticity and the specific look you want on the car. Some owners want a recognizable historic American name on the sidewall, while others are focused more on whitewall width or wheel-width compatibility. Once you know you need 670-15, compare the sidewall style and wheel fitment details first, then let brand preference break the tie.

For a 1955 Chevrolet, the Firestone 670-15 shown here is a blackwall bias-ply tire with a listed max load of 1450 pounds at 32 psi and a rim-width range of 4.50 to 5.00 inches. The Coker Classic 670-15 is a 2.75-inch wide whitewall bias-ply tire with a listed max load of 1550 pounds at 32 psi and a rim-width range of 5.00 to 6.00 inches. Their listed weights also differ, with the Firestone at 23 pounds and the Coker Classic at 21 pounds.

Those differences make the comparison more about wheel compatibility and finished appearance than about one tire being universally preferable. A car on narrower wheels may point you toward the Firestone fitment range, while a wider wheel and a more dressed-up restoration look may favor the Coker Classic. Checking the actual wheel width before selecting between them is more important than choosing by brand name alone.

1955 Chevrolet tires in 670-15 are built for 15-inch rims, but the approved rim width depends on the specific product. Firestone and US Royal examples in this size list a 4.50 to 5.00 inch rim-width range, while the Coker Classic example lists a 5.00 to 6.00 inch range. Rim width is tied to the individual tire, not just the size code alone.

That is why a quick wheel check matters before you settle on a brand or sidewall style. Two 670-15 tires can share the same nominal size and still favor different wheel widths. If your Chevrolet has replacement wheels, widened wheels, or wheels swapped during an older restoration, measure them and match the tire to the wheel rather than assuming every 670-15 fits every 15-inch rim the same way.

The 670-15 products listed for 1955 Chevrolet do not show tube-type or tubeless markings in the size line, so the practical decision usually comes back to the wheel you are using and the exact tire's construction details. Mid-1950s bias-ply applications often involve tube considerations, especially when original-style wheels are part of the equation, but the tire itself should always be checked before final installation.

A buyer should treat inner-tube selection as part of the wheel-and-tire package rather than an afterthought. Original wheels, wheel condition, valve-stem configuration, and the specific tire's sidewall marking all matter. If the car still wears factory-style wheels or older restored wheels, have the assembly reviewed by a shop familiar with collector-car fitments so the tire, tube decision, and wheel condition all work together.

A 1955 Chevrolet should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age sidewalls. Bias-ply tires also benefit from being kept at proper inflation during storage, because underinflation and long static periods encourage shape distortion and flat spotting more readily than many later radial designs.

Moving the car periodically helps change the contact patch, and some owners use tire cradles or stands during long seasonal storage. Clean, dry floors are better than damp ground, and a breathable cover over the car is more useful than wrapping the tires in a way that traps moisture. Good storage habits preserve both the rubber and the visual finish that matters on a mid-1950s Chevrolet.

On a 1955 Chevrolet, tire age usually matters more than mileage because many collector cars are driven infrequently. A sensible rule is to evaluate tires carefully once they are around five to seven years old and to treat ten years as a point where replacement deserves serious consideration regardless of tread depth. The DOT date code on the tire remains the best age reference.

A low-mileage car can still have aged-out tires that look decent at a glance, especially if it spends long periods parked indoors and only comes out for short drives. Sidewall cracking, hardening, repeated loss of pressure, and changes in ride quality can all arrive before tread wear becomes obvious. Age-based replacement planning is one of the simplest ways to protect both the car and the people in it.

Tires on a 1955 Chevrolet should be inspected before every drive and given a more thorough check before any long outing, tour, or show trip. Look for sidewall cracking, cuts, bulges, uneven tread wear, and signs that the tire has been run low on pressure. The valve stems and the spare should be part of the same routine, since collector cars often rely on equipment that has aged with the vehicle.

Frequent inspection is especially important on a car that sits for long stretches between uses. Problems that develop quietly in storage can reveal themselves only when the car is finally driven at road speed. A five-minute check with a gauge and a close visual walkaround catches many issues early and is far easier than dealing with a failure during a trip in a 1955 Chevrolet.

A 1955 Chevrolet Bel-Aire from this period would have been associated with bias-ply construction, not a later-style radial fitment. The size used across the 1955 Chevrolet models covered here is 670-15, which aligns with the kind of mid-1950s passenger-car sizing and construction a restorer expects to see. Original-equipment branding could vary by market and supply, so the more reliable authenticity markers are the size, construction, and sidewall presentation.

If you are restoring a Bel Air for a high-level judged event, treat 670-15 bias-ply fitment as the starting point and then verify sidewall style against period brochures, factory photography, and Chevrolet marque-club resources. Owners pursuing a driver-focused restoration may still want the same basic size even if they are less concerned about exact visual details. The right answer depends on whether the goal is historical accuracy, touring use, or a balance of both.

Correct tire fitment matters a great deal when a 1955 Chevrolet is judged for authenticity. Size, construction type, and sidewall style all influence whether the car looks era-appropriate, and judges or knowledgeable enthusiasts will quickly notice a tire that visually belongs to a later period. On a Tri-Five Chevrolet, the tire's sidewall appearance contributes heavily to the overall stance and character of the finished car.

A 670-15 bias-ply tire keeps the car within the expected period framework, but the exact sidewall treatment should still match the level and style of restoration you are aiming for. A blackwall can look right on a simpler presentation, while a wide whitewall can better suit a more formal mid-1950s look. Event-specific rules differ, so compare your choice against marque-club judging standards before finalizing the car.

For a 1955 Chevrolet, the US Royal 670-15 shown here is a 2 11/16-inch wide whitewall bias-ply tire with a listed max load of 1450 pounds at 32 psi and a rim-width range of 4.50 to 5.00 inches. The Firestone 670-15 is a blackwall bias-ply tire with the same listed max load of 1450 pounds at 32 psi and the same 4.50 to 5.00 inch rim-width range. Their listed weights differ slightly, with the US Royal at 22 pounds and the Firestone at 23 pounds.

Because the fitment range and load figure are so close, the real distinction is visual authenticity and the character you want the car to project. The US Royal's wide whitewall creates a more formal, dressier appearance, while the Firestone blackwall reads cleaner and more restrained. On a show-oriented restoration, that sidewall difference can change the personality of the whole car even though the basic tire size remains identical.

A properly fitted, correctly inflated 670-15 bias-ply tire in good condition can be used for normal road driving on a 1955 Chevrolet, provided the rest of the car is equally roadworthy. The key point is that these are bias-ply tires, so they deliver period-correct behavior rather than the feel of a modern radial. On a mid-1950s Chevrolet, steering, braking, suspension condition, and alignment are often just as important to highway confidence as the tire itself.

Safe highway use starts with realistic expectations and careful preparation. If the car wanders, vibrates, or reacts poorly to grooves and crosswinds, do not assume the issue is the tire alone. Verify pressures, inspect the age and condition of the tires, and make sure the chassis is sorted before asking an old Chevrolet to do sustained road work. A fresh tire helps, but the entire vehicle has to support the job.

The listed load-and-pressure figures for 1955 Chevrolet 670-15 products include 1450 pounds at 32 psi on some tires and 1550 pounds at 32 psi on another. Those figures are tire ratings, not automatic vehicle settings. The proper operating pressure for your Chevrolet should be checked against the factory recommendation for the car and then considered alongside the specific reproduction tire's published limits.

Do not transfer a pressure assumption from one product to another just because the size code matches. A load rating printed for one 670-15 may differ from another brand's version, and the car's front-to-rear needs may not mirror the tire's maximum figure. Start with the vehicle guidance, verify that it sits comfortably within the tire's rated range, and adjust only with a clear reason tied to handling, load, and wheel condition.

Before a longer drive in a 1955 Chevrolet, inspect all four tires and the spare for cracking, cuts, bulges, embedded debris, uneven wear, and proper inflation. Make sure the valve stems are sound and that each tire is holding pressure consistently. Since these cars are often used intermittently, also confirm that the tires have not developed storage-related flat spots or age-related hardening since the last outing.

The tire check should be part of a broader pre-trip routine that includes brakes, steering play, fluid levels, cooling-system condition, and lighting. A 1955 Chevrolet can be a very enjoyable road car, but it rewards owners who prepare it like a vintage machine rather than a modern appliance. Catching a weak spare, a cracked stem, or a slowly leaking tire in the garage is far better than discovering it on the shoulder.
