1973 Maserati Tire Fitment Guide

1973 Maserati fitment is straightforward: the Bora uses 215/70R15 radial tires. That size mounts on a 15-inch wheel, and the available products for it support rim widths from 5.5 to 7.5 inches depending on the tire. Since only one Maserati model appears for the year, there is no split between one model and another at the year-make level.

That simplicity means your first step is confirming that your car is in fact a 1973 Bora and that its wheels are true 15-inch pieces within the range accepted by the specific tire you want. After that, the decision shifts to sidewall appearance, speed rating, and the overall character you want the car to present rather than chasing a second factory size.

On a 1973 Maserati, 215/70R15 is a metric radial size. The 215 is the nominal section width in millimeters, 70 is the aspect ratio, the R indicates radial construction, and 15 is the wheel diameter in inches. In practical terms, that is a modern metric sizing convention that suits the Bora’s 1970s grand touring character far better than an earlier numeric or alphanumeric bias-ply code would.

Knowing how to read the code helps you compare products accurately, especially when some tires in the same size emphasize visual style while others emphasize high-speed capability. It also keeps you from confusing wheel diameter with tire width when checking your wheels, spare, or old sidewall markings. For the Bora, matching that 15-inch diameter is the non-negotiable starting point.

At the 1973 Maserati year-and-make level, the Bora is the only model covered here, and it uses 215/70R15. There is no cross-model size variation to sort through on this page, so the tire search does not branch into several different Maserati fitments for the year. The fitment question is concentrated on one model and one radial size.

That gives buyers a cleaner path than on many year-make pages, but it does not remove the need to inspect the actual car. Exotic cars can pick up wheel changes over decades of ownership, and a replacement wheel that is still 15 inches may differ in width from the original setup. Confirming the wheel before purchase is the best way to avoid an avoidable mismatch.

1973 Maserati tires in 215/70R15 are available as blackwall, wide whitewall, and raised white letter designs. Blackwall choices come from Dunlop and Avon, BFGoodrich offers a 2.50-inch whitewall, and Cooper offers a raised white letter Cobra Radial G/T. All of them share the same basic size, but they create very different visual impressions on the car.

For a Bora, blackwall is usually the closest match to the restrained European performance look most enthusiasts expect from a 1970s Italian exotic. Whitewall and raised white letter options can still fit the wheel correctly, but they push the appearance in a more personalized direction. If restoration accuracy matters, decide on sidewall style before narrowing to a brand or speed rating.

Four brands cover 1973 Maserati fitment in 215/70R15: Cooper, BFGoodrich, Dunlop, and Avon. Cooper offers the Cobra Radial G/T, BFGoodrich offers the Silvertown Radial, Dunlop offers the Sport Classic, and Avon offers the CR6ZZ. Each one is a radial, but they differ in sidewall presentation and, in some cases, in speed-rating emphasis.

That variety matters because a Bora buyer is often balancing aesthetics with use. A blackwall Dunlop or Avon keeps the look closer to a European sports-car theme, while BFGoodrich and Cooper introduce more stylized American-period sidewall treatments. Start by deciding whether the car is being finished for authentic visual balance, occasional road use, or a more custom presentation.

For a 1973 Maserati Bora in 215/70R15, both Dunlop Sport Classic and Avon CR6ZZ are blackwall radials aimed at drivers who want a sporting look. The Dunlop carries a W speed rating at 168 mph in 215/70VR15 form and a maximum load of 1,653 pounds, while the Avon is marked 98V, indicating a V speed rating at 149 mph. Avon also specifies a 5.5- to 7.0-inch rim-width range.

That makes the comparison less about basic fitment and more about the balance of appearance and operating envelope. Either one keeps the sidewall visually appropriate for a European exotic, but the specific speed marking may matter to owners who pay close attention to period-correct high-performance tire language. The right choice depends on how closely you want the tire’s presentation to match your use expectations.

For 1973 Maserati fitment in 215/70R15, approved rim widths vary slightly by tire. Cooper and Avon both fit 5.5- to 7.0-inch rims, while BFGoodrich accepts 5.50- to 7.50-inch rims. All of these tires are built for a 15-inch wheel diameter, so width becomes the main wheel measurement to verify once diameter is confirmed.

That difference is small but important. A wheel that falls comfortably within one brand’s range may sit at the edge of another’s, which can affect section shape and the final look of the tire on the car. Before choosing a specific product, measure the actual wheel or confirm its stamped width so the tire and wheel work together as intended.

The available 215/70R15 tires for 1973 Maserati are presented as radial passenger-car tires without tube-type markings in their size designations. That strongly points toward tubeless use on the correct wheel. Nothing in the size markings for these products suggests an all-tube-type fitment in the way older TT-marked collector tires would.

The important check is the wheel itself. If your Bora still carries original or older restored wheels, have the bead seats and valve areas inspected so a modern tubeless radial can seal properly. A wheel’s condition can matter just as much as the tire, especially on a hand-built collector car that may have seen decades of maintenance and restoration work.

A 1973 Maserati should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age sidewalls prematurely. Keep the tires properly inflated, avoid parking on contaminated or wet surfaces for long periods, and move the car periodically so one patch of tread is not carrying the same load month after month.

That matters on a Bora because collector cars often spend more time parked than driven, and static storage can age a tire long before the tread wears out. If the car will sit for a season, many owners use tire cradles or place the vehicle on stands to reduce long-term stress. Good storage habits preserve both the tire and the way the car feels when it returns to the road.

On a 1973 Maserati, tire life is usually governed by age rather than mileage. A collector car may cover very few miles each year, but rubber still hardens over time, so a careful evaluation around five to seven years is wise, with replacement commonly considered as tires approach the ten-year mark. The DOT date code on the sidewall is the practical reference point for that timeline.

That age-based approach is especially important on an exotic GT car that may seem fine on short local drives yet ask much more of the tire at sustained speed. Even if tread depth looks healthy, older rubber can lose flexibility and grip. Use appearance, age, and how the tire holds pressure together rather than judging only by miles driven.

Tires on a 1973 Maserati should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, and signs that the tire is losing pressure between drives. Because the Bora uses a performance-oriented radial size, also pay attention to whether the tires have become hard or noisy with age even when the tread still looks respectable.

A quick inspection takes only a minute and can prevent the kind of tire problem that spoils a road trip or risks damage to a rare car. Check the spare as well, since an aged spare may be useless when finally needed. If the car has been sitting for months, inspect more carefully on the first outing back rather than assuming everything is still road-ready.

A 1973 Maserati Bora belonged to an era when radial tires were already established on high-performance European road cars, so radial construction is the right starting point for an original-type fitment conversation. The size used here is 215/70R15, which aligns with the Bora’s 15-inch wheel fitment. Original-equipment branding could vary by market and delivery history, so size and construction matter more than assuming one universal factory brand.

For a careful restoration, begin with the correct radial size and then narrow the field by sidewall appearance. A blackwall presentation will usually look more at home on a 1970s Italian exotic than a more decorative American sidewall treatment. If the car is being judged, consult Maserati marque experts or period literature for market-specific confirmation before finalizing the exact visual style.

Correct tire fitment absolutely matters when a 1973 Maserati is prepared for judging or high-level display. Judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall style suit the car’s era and character. On a Bora, an obviously non-period sidewall treatment can stand out just as much as an incorrect wheel finish or ride height.

That does not mean every owner needs the same tire. A car built for road use can justify a different visual choice than a concours-oriented restoration, but it should still remain believable for the period. If your goal is event accuracy rather than personal taste, check the standards used by the Maserati club or judging body that will evaluate the car before you commit.

For a 1973 Maserati in 215/70R15, Cooper Cobra Radial G/T and BFGoodrich Silvertown Radial differ most in visual presentation. The Cooper uses a raised white letter sidewall, carries a 1,620-pound load rating at 35 psi, weighs 23 pounds, and fits 5.5- to 7.0-inch rims. The BFGoodrich uses a 2.50-inch whitewall, also carries a 1,620-pound load rating at 35 psi, weighs 28 pounds, and fits 5.50- to 7.50-inch rims.

For restoration-minded owners, neither choice has the understated blackwall character many associate with European exotics of the period, but they may still suit a personalized vintage presentation. The practical takeaway is that both fit the same size and diameter while changing the car’s visual tone dramatically. Choose between them based on sidewall appearance first, then verify wheel width against the specific tire.

Yes, the available 215/70R15 radials for 1973 Maserati are suitable for highway use when they are in good condition, correctly inflated, and matched to sound wheels. Among the available products, V-rated tires carry a 149 mph ceiling and the W-rated Dunlop carries a 168 mph ceiling. Those figures are far above ordinary U.S. highway speeds, so the more immediate concern on a Bora is usually tire age, chassis condition, alignment, and braking health.

That means the tire’s speed symbol should be viewed as part of a larger roadworthiness picture, not as permission to drive an older exotic carelessly. Before sustained highway use, make sure the tires are fresh enough, pressure-stable, and free of visible damage. A well-sorted Bora on sound radials can be a satisfying touring car, but any weak link in the car’s mechanical condition deserves attention first.

Inflation pressure on a 1973 Maserati should start with the factory recommendation for the Bora and then be checked against the tire manufacturer’s maximum load-and-pressure marking. In 215/70R15, Cooper and BFGoodrich both show 1,620 pounds at 35 psi, while Dunlop shows a maximum load of 1,653 pounds. Those figures describe the tire’s rated capacity, not necessarily the pressure your Maserati should run in everyday use.

The safest approach is to use the vehicle’s handbook or marque reference for baseline cold pressures, then verify that your chosen tire is being used within its own limits. Do not transfer assumptions from another size or another sports car, even if the dimensions look close. A small pressure change can alter steering feel and wear, especially on a mid-engine car with sensitive handling balance.

Before a longer drive in a 1973 Maserati, inspect each tire for cracking, cuts, bulges, embedded debris, uneven wear, and proper cold inflation. Check that the valve stems are sound, confirm the spare is usable, and make sure the tires are not old enough to raise age-related concerns even if they still look clean. A quick visual walkaround should be paired with a pressure check, not used in place of one.

On a Bora, the tire inspection should be part of a broader pre-trip routine that also covers brakes, fluids, belts, cooling, and suspension condition. Grand touring cars invite longer drives, but age can turn a minor issue into a roadside problem. If the car has been dormant, a short shakedown run close to home is smarter than heading straight into a high-speed highway trip.
