1962 Riley Tire Fitment Guide

1962 Riley vehicles use four sizes across two model groups. The Riley 4/68 and 4/72 use 165R14 in radial form or 5.90-14 in bias-ply form, both on 14-inch rims. The Riley Elf uses 155R13 in radial form or 520-13 in bias-ply form, both on 13-inch rims. Rim width guidance appears on some products: 165R14 examples cover roughly 4.0 to 6.0 inches, 155R13 reaches 4.00 to 5.50 inches, and 520-13 appears on rims around 3.5 to 4.0 inches depending on the tire.

The practical takeaway is that year and make alone are not enough for a 1962 Riley. You need to confirm whether your car is a 4/68 or 4/72, or an Elf, because the wheel diameter changes with the model. Once that is settled, the next choice is construction type: bias-ply for a more period-authentic presentation, or radial where that option exists for more contemporary road manners. Checking the actual wheel before ordering is still wise, especially on restored cars that may have changed wheels over the years.

On a 1962 Riley, 165R14 is a metric radial size used on the 4/68 and 4/72. The 165 indicates a nominal section width of 165 millimeters, the R identifies radial construction, and the 14 is the wheel diameter in inches. In this older metric style, the aspect ratio is not written into the size, and it is conventionally treated as an 80-series radial format.

That decoding matters because 165R14 is not simply another way of writing a 5.90-14. It represents a different construction type and belongs to the larger Riley saloons rather than the Elf. If you are comparing products in this size, you may also notice H-speed-rated examples and blackwall styling, which suit many drivers who want a correct-looking 14-inch radial without moving away from the overall character of an early-1960s British car.

No, 1962 Riley models do not all use the same tire size. The 4/68 and 4/72 use 14-inch sizes, with 165R14 as the radial option and 5.90-14 as the bias-ply option. The Riley Elf uses 13-inch sizes, with 155R13 as the radial option and 520-13 as the bias-ply option. Those two model groups are separate in both wheel diameter and tire sizing.

That means a buyer who only knows “1962 Riley” is still one step short of the right fitment. The larger saloons and the small Elf are very different cars, and the tire diameters reflect that. If your car has been restored, modified, or converted to another wheel set at some point, compare the tire size on the car now with the actual rim diameter before making a final decision. It prevents costly mistakes and keeps the model-specific proportions intact.

For a 1962 Riley 4/68 or 4/72, the choice between 165R14 and 5.90-14 is mainly a choice between radial and bias-ply construction within the correct 14-inch fitment family. The 165R14 is the radial option, while 5.90-14 is the period-style numeric bias-ply size. They are not interchangeable across the whole Riley range, since the Elf uses 13-inch tires instead.

Owners restoring a saloon to a distinctly early-1960s look often prefer the bias-ply route, especially when originality of stance and feel matters. Drivers who expect more regular road use often lean toward the radial because it keeps the car in the proper 14-inch category while moving to a more modern tire construction. The best approach is to decide whether your priority is restoration authenticity or road-use comfort, then confirm your wheel diameter and width before final selection.

Sidewall style varies by size on 1962 Riley vehicles. The radial sizes 165R14 and 155R13 are available as blackwalls, which suit the understated look most buyers expect on British saloons of this period. The Elf’s 520-13 bias-ply size has the widest appearance range, with both blackwall and narrow whitewall options. That gives the smallest Riley a more customizable period presentation than the radial choices do.

For a factory-like British look, blackwall is usually the safest visual direction, especially on the 4/68 and 4/72. Narrow whitewalls can make sense on a personalized or distinctly period-styled Elf, but they create a different visual statement than a plain black sidewall. If show judging or marque accuracy matters, compare your intended sidewall style to period photos, club references, and the market where the car was originally sold before settling on the final look.

Several brands cover 1962 Riley fitments, but they are tied to specific sizes. The 165R14 radial is available from Pirelli, Michelin, and Vredestein. The 155R13 radial is available from Michelin and Dunlop. The 520-13 bias-ply size is available from Firestone and Premium Sport. Brand choice therefore depends first on whether you own a 4/68 or 4/72, or an Elf, and then on whether you want radial or bias-ply construction.

That brand split can help narrow your search quickly. A buyer chasing a classic European radial feel on a larger Riley saloon will look in a different direction than an Elf owner who wants a small-diameter bias-ply with a narrow whitewall. Rather than starting with the brand name, start with the car and the correct size. Once that is settled, compare each brand’s sidewall style, construction, and any load or speed information that matters for how the car will actually be used.

Rim width guidance on 1962 Riley tires depends on the size. For 165R14, available examples span roughly 4.0 to 6.0 inches, including 4.50 to 6.00 inches and 4.0 to 5.5 inches on specific products. The 155R13 radial reaches 4.00 to 5.50 inches on at least one option. The 520-13 bias-ply size appears on rims around 3.5 inches, with another example covering 3.50 to 4.00 inches.

Those ranges are useful because many restored British cars no longer wear their original wheels. Before ordering, measure the actual rim width and confirm it falls inside the range for the exact tire you are considering, not just the size family in general. A tire that is correct in diameter can still be a poor match on the wrong rim width. If your wheels are aftermarket, this check becomes especially important for preserving both appearance and proper tire shape.

Inner-tube requirements vary by size and sometimes by product on 1962 Riley tires. The 165R14 and 155R13 radial categories include products with explicit TL, or tubeless, marking. The bias-ply 520-13 examples do not carry a uniform tube designation across the range, so tube use should be treated as product-specific rather than assumed one way or the other. Wheel design also affects the answer, especially on older cars.

The safest approach is to check both the tire’s sidewall marking and the construction of the wheel that will carry it. A tubeless-rated tire does not automatically make an older wheel suitable for tubeless service, and a bias-ply collector tire may still be paired with a tube depending on the wheel and the product. If there is any doubt, consult the tire manufacturer’s guidance and inspect the wheel condition, valve area, and bead seat before assembly.

A 1962 Riley should be stored in a cool, dry, dark place away from direct sunlight, electric motors, battery chargers, welders, furnaces, and other ozone-producing equipment. Clean the tires first, set pressures correctly, and avoid leaving the car on damp ground or bare concrete for long periods. Bias-ply tires such as 5.90-14 or 520-13 are more prone to temporary flat-spotting during static storage than radial sizes like 165R14 or 155R13.

If the car will sit for months, rolling it occasionally or supporting it so the tires are not carrying full weight can help reduce stress. A breathable car cover and a stable indoor climate do more for tire life than frequent detailing products. Collector tires often age out before they wear out, so storage conditions matter as much as mileage. Good storage preserves sidewall appearance, helps prevent cracking, and makes the first drive of the season far less eventful.

Tires on a 1962 Riley usually age out before tread wear becomes the deciding factor. For collector vehicles, a sensible rule is to begin evaluating tires closely once they are around five to seven years old and to treat ten years as a serious replacement point regardless of remaining tread depth. The DOT date code on the tire is the key age reference, not the date the car was restored or the date the tire was first mounted.

That age-based approach matters because a lightly used Riley may appear to have excellent tread while the rubber has already hardened or begun to crack internally. Annual checks by a knowledgeable vintage-tire professional are worthwhile once a set reaches mid-life. If the car spends long periods parked, sunlight, ozone, and underinflation can shorten useful life further. A low-mileage collector tire should never be judged by tread alone.

Tires on a 1962 Riley should be inspected before every drive and again before any longer outing or event. Look for sidewall cracking, weathering, cuts, bulges, uneven wear, embedded debris, and pressure loss. On sizes that may use tubes or older wheel designs, pay close attention to valve stems and any signs of leakage around the valve or bead area. Spare-tire condition matters too, especially on cars that travel any real distance from home.

Routine inspection is especially important on classic British cars because usage can be sporadic and age-related tire issues do not always announce themselves early. A five-minute walkaround can catch a soft tire, a split sidewall, or a damaged valve stem before the car gets up to speed. If the steering suddenly feels heavier, wanders more than usual, or the car develops vibration, stop and inspect the tires before continuing. Small issues on an old car can escalate quickly.

For a 1962 Riley 4/68 and 4/72, period-original fitment would have centered on bias-ply construction, reflected here by the 5.90-14 size, since radials were still a transition-era choice rather than the universal norm on many British cars. The 165R14 size represents the radial path in the same 14-inch wheel category. No specific original equipment brand should be assumed without market-specific factory literature or a well-preserved reference car.

That distinction matters if you are restoring a car for authenticity rather than simply making it drivable. A concours-minded owner will usually start with the correct size family, construction type, and sidewall appearance before worrying about brand preference. If your Riley was delivered in a different export market or has unusual trim history, a marque club or period brochure is the best way to confirm what would be considered truly original for that exact car.

Correct tire fitment absolutely matters when showing a 1962 Riley, especially in events that judge authenticity closely. Judges and knowledgeable enthusiasts often notice whether the car is wearing the right overall size family, the appropriate construction type for the era, and a sidewall style that suits the car’s period and market. A radial on a car judged for strict originality, or an eye-catching whitewall where a plain blackwall is expected, can stand out quickly.

That does not mean every show car must avoid radial tires, but it does mean the owner should understand the standard of the event. Some gatherings reward preservation and roadworthiness, while others place greater emphasis on factory-correct details. If trophies matter, settle the question before mounting a set. Club advisers, factory brochures, and period photographs are often more useful than broad internet opinion when deciding what a 1962 Riley should wear in judged presentation.

The 1962 Riley Elf would have been associated most naturally with a bias-ply fitment in period, reflected here by the 520-13 size, while 155R13 represents the radial alternative in the same 13-inch wheel class. That matches the Elf’s early-1960s place in the market, when many small British saloons still lived in a world where bias-ply tires were familiar equipment. Original equipment branding should be verified through marque-specific references rather than assumed.

For restoration work, the important first step is preserving the Elf’s correct small-diameter visual proportion. Once that is in place, the choice becomes one of authenticity versus road-use preference. A blackwall 520-13 keeps the presentation squarely traditional, while a radial 155R13 may better suit an owner who drives the car more often. If you are building an Elf for a judged event, check whether sidewall style and construction type are part of that event’s scoring priorities.

1962 Riley tires can be suitable for highway driving when they are in the correct size, correctly installed, properly inflated, and used within their construction and speed limits. The radial sizes 165R14 and 155R13 include H-rated examples, which carry a 130 mph ceiling in tire-rating terms. That figure does not mean a 1962 Riley should be driven anywhere near that speed; the car’s brakes, suspension, road conditions, and overall mechanical condition are far more important in real use.

For normal modern traffic, the larger concern is usually age, condition, and setup rather than raw speed rating. A fresh radial in the right size may feel more settled on regular road trips, while a proper bias-ply remains entirely appropriate for period-style use when kept in good condition and driven with classic-car expectations. Before taking any 1962 Riley onto faster roads, inspect the tires, confirm pressures, and be honest about the car’s total mechanical readiness.

Inflation pressure on a 1962 Riley should begin with the vehicle manufacturer’s original recommendation for the car and then be checked against the tire maker’s own maximum pressure and load information for the exact size you are using. Available examples include 165R14 with a load figure of 1,102 pounds at 51 psi, 520-13 examples at 770 at 32 psi and 1,100 at 60 psi, and 155R13 with a 937-pound load figure on one product. Those are tire capability references, not universal running pressures.

The important mistake to avoid is transferring a pressure from one Riley size to another just because both belong to the same year. A 13-inch Elf tire and a 14-inch saloon tire are different cases, and even two tires in the same size may carry different construction details. Start with the car’s handbook or marque guidance for baseline operating pressure, then confirm that your chosen tire is being used within its stated limits. Recheck pressures when the tires are cold.

Before a longer drive in a 1962 Riley, inspect all four tires and the spare for cracking, cuts, bulges, punctures, uneven wear, and correct cold pressure. Check valve stems carefully, especially where older wheels or tube-type setups may be involved, and make sure each wheel fastener is secure. On the road-car side, longer trips also call for a quick check of brakes, cooling system, lights, and fluid levels, since tire readiness is only one part of preparing an early-1960s car.

A good pre-drive routine reduces the chance of turning a pleasant run into a roadside repair. Bring a pressure gauge, confirm the jack and spare are usable, and pay attention to any vibration or pull in the first few miles. If the car has been sitting, allow a short shakedown drive before committing to a long route. That approach helps the tires settle, reveals any air loss early, and gives the whole car a chance to show problems close to home.
