Chrysler Newport Custom Tires
The Chrysler Newport Custom sat in Chrysler’s full-size lineup during an era when large American sedans still prioritized comfort, presence, and easy highway cruising. For 1972, Chrysler Newport Custom represented the traditional domestic car formula of generous proportions, body-on-frame engineering, and broad tire fitment choices tied to how a particular car was equipped. Tire selection is not entirely straightforward here because the model uses more than one size in the same model year, even though both fit the same 15-inch wheel diameter. Anyone choosing tires for a Chrysler Newport Custom should first confirm the exact size shown on the car, then match sidewall style and construction to the intended level of originality and use.
Chrysler Newport Custom Tire Size Guide
Chrysler Newport Custom uses 2 distinct tire sizes across the 1972 production year. Both sizes are alphanumeric bias-ply sizes built for 15-inch wheels, so the key difference is not rim diameter but the width and fitment choice tied to the specific car. The letter in each size identifies a width and load class, while the 78 indicates the aspect profile used in this period and the final 15 is the wheel diameter in inches.
H78-15 fits certain 1972 Chrysler Newport Custom applications and is offered here on 15-inch rims with a 5.50 to 7.00 inch rim width range. The H identifies the tire's size class, the 78 is the aspect series used in period alphanumeric sizing, and the 15 is the wheel diameter in inches. Choose H78-15 when that size matches the car's existing fitment or reference material, and note that the available products are bias-ply designs with a tube required.
J78-15 fits certain 1972 Chrysler Newport Custom applications and is also built for 15-inch rims using a 5.50 to 7.00 inch rim width range. The J identifies a larger alphanumeric size class than H, the 78 is the aspect series, and the 15 is the wheel diameter in inches. Choose J78-15 only when the specific car calls for it, and note that the available products are bias-ply designs with a tube required.

Frequently Asked Questions
The FAQ below focuses on the two-size 1972 Chrysler Newport Custom fitment, how alphanumeric bias-ply sizes differ, which sidewall styles and brands are available, and what collector owners should know about storage, inspection, and road use.
Size Basics & Fitment
Chrysler Newport Custom uses two listed tire sizes for 1972: H78-15 and J78-15. Both sizes are bias-ply alphanumeric tires built for 15-inch rims, and the available products for both sizes specify a 5.50 to 7.00 inch rim width range. H78-15 is offered in wide whitewall and blackwall versions, while J78-15 appears in narrow whitewall and dual-white-stripe form.
The important point is that a 1972 Chrysler Newport Custom cannot be matched by year alone. Check the size currently on the car, compare it with factory literature or restoration records, and make sure the wheel is a 15-inch rim before choosing between H78-15 and J78-15. Sidewall appearance can then be selected to suit a factory-style restoration or a more individual period look.
H78-15 is an older alphanumeric bias-ply tire size used on certain 1972 Chrysler Newport Custom applications. The H identifies the tire’s size and load class within the period alphanumeric system, the 78 refers to the aspect profile used in that era, and the 15 is the wheel diameter in inches. The available H78-15 products here all fit 15-inch rims and list a 5.50 to 7.00 inch approved rim width range.
That decoding matters because H78-15 is not interchangeable with every other 15-inch collector tire. A Chrysler Newport Custom owner should match the exact size designation, not just the wheel diameter, especially when preserving original stance and appearance. Once H78-15 is confirmed, the next decision becomes sidewall style and whether a standard passenger look or a blackwall truck-style option best suits the car’s intended use.
A 1972 Chrysler Newport Custom has two listed tire sizes because the model year includes a fitment split rather than a single universal size. Both H78-15 and J78-15 use the same 15-inch wheel diameter and the same 5.50 to 7.00 inch rim width range, so the difference is not a wheel-size change. The split points to variation within the model line, such as trim, body style, or equipment choice.
That means the right approach is to identify the specific car first and the tire second. Check the original size marking, compare wheel and tire details with period references, and avoid assuming that every 1972 Chrysler Newport Custom used the same tire. This is especially important on a restoration where the visual proportion of the tire can change the car’s stance and overall correctness.
The listed Chrysler Newport Custom tire options are all bias-ply products in period alphanumeric sizing, and the fitment guidance for these selections calls for a tube required. That applies to both H78-15 and J78-15 in the available offerings. Even though the wheel diameter is a straightforward 15 inches, the tube requirement remains part of the proper setup for these listed tires.
A Chrysler Newport Custom owner should treat tube selection as part of the tire fitment, not as an afterthought. The tube needs to match the tire size and be installed with proper rim preparation so the assembly functions as intended. This is particularly important on a collector car that may sit for long periods and then return to service for occasional touring, shows, or local road use.
Buying the Right Tire
A 1972 Chrysler Newport Custom can use either H78-15 or J78-15, and both are 15-inch bias-ply sizes. The quickest factual check is the size stamped on the tire currently fitted to the car, followed by the wheel diameter and the approved rim width range of 5.50 to 7.00 inches. That separates wheel fit from the actual tire-size choice, which is where most confusion starts.
After confirming what is on the car, compare it with the car’s original paperwork, restoration records, or marque references so the size matches the specific configuration rather than just the model year. Then choose the sidewall style that suits the intended result. That process helps preserve proper proportion and avoids replacing a correct period-looking setup with a different size that simply happens to fit a 15-inch wheel.
Chrysler Newport Custom tire options here include several sidewall styles. H78-15 is offered as wide whitewall and blackwall, while J78-15 is offered as narrow whitewall and dual-white-stripe. Those choices give the 1972 Chrysler Newport Custom owner several distinct visual directions while staying within period bias-ply sizing.
Sidewall style changes the look of a full-size Chrysler as much as the wheel cover or paint trim. A whitewall or dual stripe generally suits a more factory-flavored restoration, while blackwall can work for a plainer period appearance or a more utilitarian presentation. The best practice is to match the style to the car’s original delivery character and overall restoration goal after the correct size has been confirmed.
The listed Chrysler Newport Custom tire brands are Coker Classic, STA, and BFGoodrich. Coker Classic appears in H78-15 wide whitewall versions, STA appears in H78-15 blackwall form, and BFGoodrich appears in J78-15 narrow whitewall and dual-white-stripe versions. All of the available products for this page are bias-ply tires sized for 15-inch wheels.
Brand selection should come after the size is settled, because not every brand appears in both listed sizes. Once the car’s correct H78-15 or J78-15 fitment is identified, the remaining choice is really about appearance and intended presentation. That makes it easier to choose between a broader whitewall look, a narrow stripe treatment, or a blackwall style that better matches the character of the specific Chrysler Newport Custom.
Chrysler Newport Custom tires here are offered in two distinct series families: Coker Classic Bias Ply and Traxion, with BFGoodrich products listed under the Silvertown Classic Bias Ply series. The Coker Classic Bias Ply and Silvertown Classic Bias Ply lines are passenger-car styled bias-ply options, while Traxion is identified separately and appears alongside a Military & Truck attribute in H78-15. All remain 15-inch bias-ply fitments, but the series names point to different visual and usage character.
That difference matters most when the car has a specific restoration goal. A traditional passenger-car presentation usually starts with the bias-ply passenger series in the correct size and sidewall style, while the Traxion option suits a different look entirely. Compare the series with the sidewall treatment you want and keep the final choice anchored to the exact H78-15 or J78-15 size that belongs on the individual Chrysler Newport Custom.
Maintenance & Longevity
A Chrysler Newport Custom should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and major temperature swings. Clean the tires first, make sure inflation is set appropriately for storage, and avoid leaving the full weight of a large full-size car on one spot for very long periods. If the car will sit for months, rolling it occasionally or supporting it correctly can help reduce flat spotting.
Storage matters especially on a big 1972 Chrysler because the vehicle’s weight can stress a bias-ply tire that sees limited use. Good storage habits preserve sidewall appearance, improve ride quality when the car comes back out, and help the owner catch gradual air loss before it becomes a problem. Collector cars age tires more from time and environment than from mileage, so storage conditions are a major part of tire life.
Tires on a Chrysler Newport Custom should be inspected before every meaningful drive and more thoroughly several times a year, even if the car covers very few miles. Look for cracking, weathering, bulges, irregular tread wear, valve issues, and any signs that the tube or rim may be contributing to air loss. A bias-ply collector tire can look serviceable at a glance while still developing age-related concerns that deserve attention.
A practical routine is to check pressure and visual condition before each outing, then have the tires and wheels examined closely during seasonal service or before longer trips. That inspection interval is especially important on a collector Chrysler that may spend long periods parked between events. Frequent checks are one of the simplest ways to protect both the tire investment and the drivability of the car.
Tires on a Chrysler Newport Custom should be replaced when age, cracking, hardening, separation, repeated air loss, or impact damage shows that the casing is no longer trustworthy, even if tread depth still appears good. Collector-car tires often age out before they wear out, particularly on low-mileage full-size cars that spend more time stored than driven. Tread alone is never the full measure of serviceability on an older bias-ply tire.
The right time to replace is when condition and age begin to compromise confidence, ride quality, or safety rather than waiting for visible tread wear. Owners of a 1972 Chrysler Newport Custom should include the tube, rim condition, and overall wheel assembly in that decision. A conservative replacement schedule is often the wiser approach on a large, heavy collector car where stable road manners depend heavily on tire condition.
Restoration & Authenticity
The listed Chrysler Newport Custom fitments for 1972 are H78-15 and J78-15, both in bias-ply construction and both for 15-inch wheels. The available series include Coker Classic Bias Ply, Silvertown Classic Bias Ply, and Traxion, with sidewall styles ranging from blackwall to wide whitewall, narrow whitewall, and dual-white-stripe. More than one period-style presentation is therefore represented within the available options.
For an owner restoring a Chrysler Newport Custom to exact factory appearance, the best reference is the specific car’s original literature, broadcast sheet, window sticker, or marque-club guidance. That will help narrow whether the car should wear H78-15 or J78-15 and which sidewall style most closely matches how it left the showroom. The tire should support the car’s identity, not just physically fit the wheel.
Correct tire fitment can absolutely affect how a Chrysler Newport Custom is judged and how convincingly it presents as a restoration. Size, construction, and sidewall style all influence stance and authenticity, especially on a large early-1970s American car where whitewall treatment is visually prominent. A car wearing the wrong alphanumeric size or the wrong sidewall style can look noticeably off even to a casual observer.
For owners concerned with show judging or long-term value, tire selection should follow the same careful thinking as paint codes, trim details, and wheel covers. Marque clubs and period photos are often the best reference points for what suits a particular Chrysler Newport Custom configuration. Getting the tire right helps the car sit properly and reinforces the overall credibility of the restoration.
Chrysler Newport Custom tire options here include wide whitewall, narrow whitewall, dual-white-stripe, and blackwall styles. Any one of those can be physically appropriate only if it is paired with the correct size, since H78-15 and J78-15 do not share the same sidewall options in the available range. On a 1972 full-size Chrysler, sidewall style is a major visual cue and should be chosen carefully.
A faithful restoration usually starts by matching the sidewall style to the car’s original trim level, delivery appearance, and intended presentation. Broad whitewalls and stripe treatments often suit more formal or higher-trim period character, while blackwall can fit a plainer look. Once the correct H78-15 or J78-15 size is established, period photos and original paperwork are the most useful guides to the right finishing touch.
Safety & Road Use
These tires can be suitable for public-road use on a Chrysler Newport Custom when the correct size is chosen, the tires are in sound condition, and the wheel and tube setup are properly matched. The listed options are bias-ply 15-inch tires, so they should be approached as period-style collector tires rather than modern touring-car tires. Safe use depends on condition, inflation, alignment, and the overall mechanical state of the car.
For a large 1972 Chrysler Newport Custom, road safety starts with a thorough pre-drive evaluation rather than assuming a visually attractive tire is automatically ready for service. Bias-ply behavior, braking feel, and steering response differ from modern radials, so the driver should adapt expectations accordingly. A careful owner treats the whole car as a system and confirms that suspension, brakes, wheels, and tires are all ready for the road.
Before driving a Chrysler Newport Custom, check tire pressure, sidewall condition, tread condition, valve stems, and any signs of tube-related air loss. Confirm that the car is wearing the correct H78-15 or J78-15 size for its configuration and that all four tires match in construction and general condition. On a collector car of this size, it is also wise to inspect wheel hardware, steering response, and brake feel before heading out.
A short walk-around and a few minutes in the garage can prevent the most common tire-related problems. Collector cars often sit long enough for pressure to drop or flat spotting to develop, and a full-size Chrysler makes those issues more noticeable once underway. If anything feels unusual in the first miles, stop and recheck rather than pushing on and hoping the problem resolves itself.
A Chrysler Newport Custom on period-style bias-ply tires should be driven at prudent, moderate speeds that respect the behavior of vintage construction, the age-conscious nature of collector equipment, and the condition of the individual car. Even when the tire size is correct, a bias-ply setup will not feel like a modern radial at highway speed. Ride, tracking, and braking response should all be judged with that in mind.
The practical approach is to build speed gradually, pay close attention to stability and steering feel, and keep the car within a pace that feels composed and predictable. That is especially important if the Chrysler Newport Custom has spent long periods in storage or has recently been returned to the road. Sensible speed is part of preserving both the tires and the car, not just a matter of comfort.
