1960 Sunbeam Tire Fitment Guide

1960 Sunbeam fitment depends on the model. The Alpine uses 13-inch sizes: 155R13, 560-13, 165R13, and 600-13. The radial Alpine sizes mount on 13-inch rims with rim-width ranges of 4.00 to 5.50 inches for 155R13 and 4.50 to 6.00 inches for 165R13 where that specification is available. The bias-ply Alpine sizes use narrower wheel ranges, including 3.50 to 4.00 inches and 4.00 to 4.50 inches depending on the tire. The Rapier uses 15-inch sizes: 155R15 radial and 560-15 bias-ply, with 4.00 to 5.50 or 4.50 to 5.50 inch wheel ranges appearing among available products.

The practical takeaway is simple: identify the model before anything else. An Alpine owner should stay within the 13-inch family, while a Rapier owner should stay within the 15-inch family. After that, compare construction type, sidewall appearance, and the wheel-width range that matches the actual rim on the car. That approach keeps you from mixing wheel diameters and helps narrow the search to tires that suit either a traditional restoration or a more road-oriented setup.

On a 1960 Sunbeam, 560-13 is a numeric bias-ply size. The 5.60 figure is the tire's nominal section width in inches, and the 13 is the wheel diameter in inches. Unlike a modern metric radial code, this older numeric format does not spell out an aspect ratio in the size itself. For the 1960 Sunbeam Alpine, 560-13 is one of the period-style 13-inch bias-ply options and appears in both narrow whitewall and wide whitewall versions.

That matters because 560-13 is not just a number match; it signals an older construction style and a more traditional visual presentation. If your Alpine is being restored with a period-correct look in mind, that numeric size is often the right place to start. It is also important to compare the actual wheel to the tire's approved rim-width range, since some 560-13 products suit a 3.50 to 4.00 inch wheel and others are intended for slightly wider 4.00 to 4.50 inch applications.

On a 1960 Sunbeam, 155R13 and 155R15 are Euro-metric radial sizes. The 155 is the nominal section width in millimeters, the R indicates radial construction, and the final number is the wheel diameter in inches. In this style of sizing, the aspect ratio is not printed, but the conventional interpretation is an 80-series radial profile. For 1960 Sunbeam models, 155R13 belongs to the Alpine and 155R15 belongs to the Rapier, so the last number is just as important as the width.

For a buyer, that means the size code tells you both the construction family and the wheel diameter at a glance. It also helps explain why a 155 radial for an Alpine cannot be treated the same as a 155 radial for a Rapier. Once the wheel diameter is confirmed, you can compare details such as tube-type versus tubeless marking, brand, and speed rating within that size to choose the version that best fits how the car will actually be used.

No. 1960 Sunbeam models do not share one universal tire size. The Alpine uses four 13-inch sizes across radial and bias-ply construction: 155R13, 560-13, 165R13, and 600-13. The Rapier uses two 15-inch sizes: 155R15 radial and 560-15 bias-ply. That means the model determines the wheel diameter first, then the construction and exact size narrow the choice further.

That difference is especially important when a car has changed hands several times or has had wheels swapped over the years. An owner who knows only that the car is a 1960 Sunbeam could easily start in the wrong wheel-diameter family. Confirming whether the car is an Alpine or Rapier avoids that mistake and gives you a cleaner path to choosing between a radial setup for more modern road use or a bias-ply setup for a more period-oriented presentation.

That depends on how your 1960 Sunbeam is used and what you want the car to look and feel like. Alpine owners choose between radial sizes 155R13 or 165R13 and bias-ply sizes 560-13 or 600-13. Rapier owners choose between 155R15 radial and 560-15 bias-ply. Radials here are blackwall tires, while the bias-ply options lean into period-style whitewall presentation. The construction choice is often as important as the size choice because it affects the car's visual character and road feel.

A restoration focused on era-correct appearance usually starts with the bias-ply family, especially where whitewall styling matters. A Sunbeam that will spend more time on modern roads often leads owners toward the radial family, particularly if they want a tire that feels more familiar in present-day driving. Whichever direction you take, keep the decision within your model's correct wheel diameter first, then compare the exact size, sidewall look, and wheel-width range against the wheels actually on the car.

1960 Sunbeam sidewall style depends heavily on size and construction. The radial sizes 155R13, 165R13, and 155R15 are blackwall tires. The bias-ply sizes 560-13, 600-13, and 560-15 are available with narrow whitewall and wide whitewall treatments, depending on the brand and size. That gives Alpine and Rapier owners very different visual directions depending on whether they stay with a radial blackwall or move to a classic bias-ply whitewall tire.

For a British sporting car such as a Sunbeam Alpine, blackwall radials often look more in step with a European road-use presentation. For owners aiming at a distinctly period showroom or restoration feel, the whitewall bias-ply options create a more vintage appearance, especially on cars finished in a more formal style. The best choice comes down to your model, your target look, and whether authenticity for judging or a preferred on-road feel takes priority.

Several brands cover 1960 Sunbeam fitments, but they differ by size. 155R13 and 165R13 are available from Michelin and Dunlop. 560-13 comes from BFGoodrich and Firestone, while 600-13 is available from BFGoodrich. On the Rapier side, 155R15 comes from Firestone and Michelin, and 560-15 is available from Firestone and US Royal. That mix gives owners access to both European-style radial offerings and classic American-brand bias-ply whitewall choices.

Brand selection matters most after the correct model and size are settled, because each size family carries its own character. A Michelin or Dunlop radial may appeal to the owner who wants a more European-correct blackwall look on a small British car, while BFGoodrich, Firestone, or US Royal bias-ply options often suit a more vintage visual theme. Once the size is fixed, compare sidewall style, tube marking, speed rating, and wheel-width compatibility rather than choosing on brand name alone.

Rim-width requirements for 1960 Sunbeam tires vary by size. Alpine radial 155R13 fits 4.00 to 5.50 inch rims, while 165R13 fits 4.50 to 6.00 inch rims. Alpine bias-ply 560-13 appears with ranges of 3.50 to 4.00 inches and 4.00 to 4.50 inches depending on the product, and 600-13 uses 4.00 to 4.50 inch rims. Rapier radial 155R15 fits 4.00 to 5.50 inch rims where specified, and Rapier bias-ply 560-15 appears on 4.5 inch rims or within a 4.50 to 5.50 inch range depending on the tire.

The key is to measure or confirm the actual wheel before choosing a tire. Two tires with the same nominal size can still favor different wheel widths, especially in older bias-ply fitments. That is one reason a quick visual identification is not enough on a collector car. Matching the tire's approved rim-width range to the wheel on the car helps the tire seat correctly and keeps the car's proportions and handling behavior closer to what the tire was designed to deliver.

Inner-tube requirements on 1960 Sunbeam tires depend on the exact tire within the size, especially in the radial 15-inch category. 155R13 includes tubeless and unstated examples, 165R13 includes tubeless examples, and 155R15 varies by product, with both tube-type and tubeless markings present. The bias-ply sizes 560-13, 600-13, and 560-15 do not carry tube markings in the size descriptions shown here. On an older car, wheel design and condition still matter even when a tire itself is marked tubeless.

That means you should not assume every tire in the same size uses the same setup. Check the sidewall marking on the exact product and consider the wheel's original design, sealing surface, and condition before finalizing the installation plan. On a British collector car with older wheels, tube choice can be part tire question and part wheel question. If originality or wheel condition is a concern, a Sunbeam specialist or experienced vintage tire installer is a sensible second opinion.

A 1960 Sunbeam should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber faster. Keep the tires clean, maintain proper inflation, and move the car periodically so one section of the tread is not carrying the load for months at a time. Bias-ply tires are more prone to temporary flat-spotting during long static storage than radials, so Alpine or Rapier owners running numeric bias-ply sizes should be especially mindful of that.

If the car will sit for an extended season, many collectors either roll the car occasionally or support it in a way that reduces prolonged stress on the tires without leaving the suspension hanging unnaturally. A breathable cover and a clean floor also help. Good storage habits protect more than appearance; they reduce the chance that a tire which looked fine when parked develops cracks, flat spots, or casing stress before the next driving season begins.

Tires on a 1960 Sunbeam should be judged more by age and condition than by mileage. Collector cars often wear out tires chemically long before they wear them out by tread depth, so a useful rule is to evaluate them closely once they are around five to seven years old and to treat ten years as a strong replacement point even if they still look presentable. The DOT date code on the tire is the place to confirm age, regardless of whether the car is an Alpine or Rapier.

That timeline matters because many Sunbeams cover limited annual miles and spend long periods parked, which can hide age-related deterioration. A low-mile tire is not automatically a good tire if the rubber has hardened, the sidewalls have begun to crack, or the casing has been stressed by years of static storage. Owners who drive only to local shows are often the most tempted to stretch tire age, but age is still a safety issue even on a lightly used collector car.

Tires on a 1960 Sunbeam 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. If your car uses a tube-type tire or a tube-installed wheel-and-tire combination, include the valve stem and the area around it in the inspection. A quick walkaround matters just as much on a short fair-weather trip as it does on a tour.

That routine is especially worthwhile on older British cars because they may sit for stretches between drives, and problems often appear while the car is parked rather than while it is moving. An inspection also gives you a chance to catch wheel or suspension clues, such as odd wear patterns or one tire sitting lower than the rest. If anything looks questionable, resolve it before the drive rather than assuming a low-mile collector car will be fine for one more outing.

A 1960 Sunbeam Alpine would originally have been associated with bias-ply construction in period, as that was still the standard tire type for most passenger cars at the time. Within the Alpine's fitment family, 560-13 and 600-13 represent the period-style bias-ply choices on 13-inch wheels, while 155R13 and 165R13 reflect later radial alternatives that suit owners who drive more regularly. Original-equipment branding could vary by market and delivery region, so the safest historically grounded starting point is to match the size family, wheel diameter, construction type, and sidewall style first.

If you are restoring an Alpine for authenticity, treat the exact tire choice as part of the car's presentation rather than a purely mechanical decision. Show standards may differ between British-car clubs, local concours events, and marque-specific gatherings. A period-correct bias-ply with an appropriate sidewall appearance will usually align more closely with originality expectations than a modern radial, but event-specific guidance from a Sunbeam club or restoration specialist is still worthwhile before making the final call.

Yes, correct tire fitment matters on a 1960 Sunbeam if the car is being judged for authenticity. Size, construction type, wheel diameter, and sidewall appearance all affect whether the car looks period-appropriate. On an Alpine or Rapier restored to stock form, a modern-looking mismatch in size family, an incorrect wheel diameter, or a sidewall style that does not suit the car's era can draw attention even when the rest of the restoration is carefully done. Judges and knowledgeable enthusiasts notice tires because they visually frame the entire car.

That does not mean every show car must wear the same tire, but it does mean the choice should be intentional. A radial blackwall may be perfectly acceptable on a touring-oriented driver, while a concours-minded restoration often leans toward a bias-ply tire with the right vintage presentation. If a specific event has strict originality rules, check its judging standards or ask a marque club before committing. That small extra step can prevent an otherwise excellent restoration from losing points on something highly visible.

For a 1960 Sunbeam Alpine in 155R13 or 165R13, Michelin XAS-family tires and Dunlop SP Sport Aquajet tires are both blackwall radials with H speed ratings to 130 mph. Michelin examples in those sizes use tubeless markings on the versions shown here, while Dunlop carries stated load capacities of 937 pounds in 155R13 and 1,047 pounds in 165R13. Michelin radial products in 155R13 fit 4.00 to 5.50 inch rims, and in 165R13 they fit 4.50 to 6.00 inch rims, giving a clear wheel-width framework for those applications.

For a buyer, the comparison is less about one being universally superior and more about matching the tire to the wheel and the intended character of the car. Both belong to the same broad radial family, so the finer points become rim compatibility, tube marking, and whether you prefer one brand's heritage and visual details over another's. On a compact British sports car, those small differences can matter more than broad marketing claims, especially when trying to preserve the right balance of look, stance, and usability.

1960 Sunbeam tires can be suitable for highway driving when they are the correct size, properly installed, in sound condition, and used within their construction and speed-rating limits. The radial sizes here include H-rated products to 130 mph in 155R13 and 165R13, while 155R15 appears with T- and H-rated versions, meaning 118 to 130 mph depending on the tire. Bias-ply choices in 560-13, 600-13, and 560-15 do not show modern speed-letter markings in the same way, so they should be treated with the more conservative expectations appropriate to vintage tire construction.

In real use, the car itself is usually the limiting factor before the speed rating becomes relevant. A 1960 Sunbeam is a light, older British design with era-specific brakes, steering, and suspension behavior, so mechanical condition matters as much as the tire. For normal highway driving, a healthy radial setup often aligns better with modern traffic expectations, while a bias-ply setup can still be appropriate when the car is driven in a way that respects its age and the tire's intended character.

Inflation pressure on a 1960 Sunbeam should start with the car's original manual or marque guidance, then be checked against the exact tire's rating details rather than borrowed from another size. Among the bias-ply Alpine sizes, 560-13 carries a maximum load of 850 pounds at 30 psi and 600-13 carries 1,010 pounds at 32 psi. On the Rapier side, 560-15 carries 970 pounds at 32 psi, while 155R15 radial examples include a 1,045-pound rating at 44 psi. Those are tire capacity figures, not blanket vehicle inflation prescriptions.

That distinction matters because maximum rated pressure is not automatically the correct running pressure for the car. Tire construction, wheel width, vehicle weight distribution, and intended use all influence where the tire should be set in service. The best practice is to begin with the vehicle recommendation when available, then confirm that the exact reproduction or radial tire you choose is being used within its rated limits. Avoid transferring a pressure from one size family to another simply because the tires look similar.

Before a longer drive in a 1960 Sunbeam, inspect each tire for sidewall cracking, cuts, bulges, exposed cords, and uneven tread wear, then confirm that all four are holding the intended pressure. Check the valve stems, and pay extra attention if the car uses a tube-type setup or older wheels that may have sealing concerns. The spare deserves the same inspection, since a long trip on an aged or flat spare is rarely a good fallback plan. A quick visual check is not enough if the car has been sitting for weeks or months.

Tires are only one part of the pre-drive routine on a 1960 Sunbeam, but they are the part in constant contact with the road. After the tire check, it makes sense to look over wheel fasteners, brakes, fluid levels, steering play, and basic lighting before heading out. On an older British car, small issues have a habit of becoming larger ones once the trip is underway. A careful inspection before departure usually takes less time than dealing with preventable trouble on the shoulder.
