1962 Triumph Sedan Tires

The 1962 Triumph Sedan uses two tire sizes: 145R13 in radial construction and 520-13 in bias-ply construction. Both sizes are built for 13-inch rims, so the fitment question is less about wheel diameter and more about which construction and tire style match the car’s present setup.

A car kept in a more period-style configuration may suit the 520-13 bias-ply size, while a radial-equipped setup may point toward 145R13. The right choice depends on the wheel width, the overall condition of the suspension and steering, and whether the goal is traditional appearance, road manners, or a balance of both.

The 1962 Triumph Sedan uses a 13-inch rim diameter with both of its applicable tire sizes. That shared diameter simplifies the first fitment step, because both the 145R13 radial and the 520-13 bias-ply are intended for 13-inch wheels rather than different wheel diameters.

Rim diameter is only part of the fitment picture, so wheel width still deserves attention before choosing between the available tires. Some products in these sizes include specific rim-width guidance, and that matters when a car has replacement wheels, older wheels of uncertain size, or changes made during restoration or prior ownership.

520-13 is a vintage numeric bias-ply tire size. The 520 designation refers to an approximate 5.20-inch nominal section width, and the 13 indicates the wheel diameter in inches. On a 1962 Triumph Sedan, that size represents the traditional bias-ply fitment rather than the radial alternative.

Understanding that format helps when comparing period-style tires, because modern buyers are often more familiar with metric radial sizing. A 520-13 choice also opens the door to appearance decisions such as blackwall, narrow whitewall, or wide whitewall, so the final selection can reflect both the car’s visual character and its current wheel setup.

520-13 is a bias-ply tire size for the 1962 Triumph Sedan. It uses the older numeric sizing system and is separate from the car’s 145R13 radial fitment, even though both sizes are intended for 13-inch rims.

That distinction matters because construction affects both presentation and selection. A bias-ply 520-13 can suit an owner looking for a more traditional look, especially with whitewall options, while a radial choice moves the car into a different tire format. Wheel width, suspension condition, and the car’s intended use should all be checked before changing construction.

Radial equivalents for 520-13 include 155R13, P155/75R13, and P155/70R13. Those cover three different radial sizing approaches: an 80-series metric radial, a 75-series P-metric radial, and a 70-series P-metric radial.

Each equivalent gives a useful comparison point when moving away from a bias-ply tire, but none should be treated as automatic interchangeability. The recommended rim-width range attached to the equivalent group is 4 to 5 inches, and it remains important to confirm wheel width, overall clearance, and the way the car currently sits before making a change.

The 1962 Triumph Sedan supports both approaches, with 520-13 in bias-ply construction and 145R13 in radial construction. Choosing between them comes down to how the car is being finished and used, since the decision affects both the tire’s visual character and the overall setup.

A bias-ply tire makes sense for owners pursuing a more vintage presentation, especially when whitewall styling matters. A radial can be the better direction when the car has already been set up around radial dimensions and compatibility. Either way, checking wheel width, clearance, and the condition of steering and suspension parts helps prevent fitment surprises.

Start with the two correct fitment paths for the 1962 Triumph Sedan: 520-13 in bias-ply construction or 145R13 in radial construction. From there, compare the tire’s construction type, wheel compatibility, sidewall style, and whether the overall look should lean more toward period-style restoration or a simpler blackwall radial presentation.

Product details can also help narrow the choice. Some tires include rim-width guidance, load figures, or series differences that matter on a light vintage sedan. A careful selection usually comes from matching the tire not only to the size code, but also to the car’s existing wheels, intended road use, and desired appearance.

1962 Triumph Sedan tires are available in several sidewall styles, depending on size and construction. The 145R13 radial options are blackwall, while 520-13 bias-ply choices include blackwall, narrow whitewall, and wide whitewall treatments.

That range gives the owner room to shape the car’s appearance without stepping outside the correct basic fitment. A blackwall keeps the presentation understated, while narrow and wide whitewalls add more visual emphasis. The best match depends on how the sedan is being restored, the look of the wheels and trim, and whether authenticity-inspired style is a priority.

The 1962 Triumph Sedan has tire options from Michelin, Firestone, and Premium Sport. Michelin and Firestone appear in the 145R13 radial size, while Firestone and Premium Sport are available in the 520-13 bias-ply size.

Brand choice should be viewed as part of a broader selection process rather than the only decision. Tire series, sidewall treatment, construction type, and wheel compatibility all matter just as much on a vintage sedan. Once the correct size and construction path are settled, comparing the remaining brand and series differences becomes much more straightforward.

For a period-style 1962 Triumph Sedan, the 520-13 bias-ply size is the most natural starting point. It uses the vintage numeric format and is available in several appearance-driven versions, including blackwall, narrow whitewall, and wide whitewall styles.

That does not automatically make one specific brand or whitewall width historically exact for every car. When originality matters at a higher level, compare the tire choice against period photos, marque references, and restoration documentation for the particular sedan. For many owners, though, staying with the bias-ply size captures the proper visual character.

Tire construction changes the visual character of a restored 1962 Triumph Sedan as much as it changes the fitment path. A 520-13 bias-ply generally supports a more traditional vintage presentation, while a 145R13 radial reads as a more modern tire format even though it still fits the car’s 13-inch wheel diameter.

Sidewall treatment adds another layer to that decision. Whitewall bias-ply tires can strongly shape the car’s stance and period feel, while blackwall radials keep the look cleaner and simpler. Owners trying to balance authenticity-inspired appearance with regular road use should decide first which visual direction matters more before narrowing the product list.

Yes, modifications can affect tire fitment on a 1962 Triumph Sedan even when the tire size itself is correct. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body and fender repairs can all influence how a 145R13 or 520-13 tire sits on the car.

That matters most on older vehicles that may have been changed over decades of use. A sedan with replacement wheels should have its actual rim diameter and width confirmed before ordering tires. Clearance at full steering lock and through suspension travel also deserves attention, especially when moving between bias-ply and radial constructions.

Before driving a 1962 Triumph Sedan on new tires, inspect the wheels, valve stems, and the visible condition of steering and suspension components. It is also wise to confirm that the tire size matches the wheel diameter, that inflation is correct for the chosen tire, and that there is no interference at normal ride height.

A short, careful road test is a smart next step after installation. Listen for rubbing, watch for pull or vibration, and recheck pressure after the tires have settled. On a collector car that sees limited mileage, keeping an eye on air loss, tread condition, and early signs of sidewall aging remains just as important as the initial fitment.

Tires on a collector 1962 Triumph Sedan should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Even a lightly driven car can develop cracking, flat spotting, air loss, or sidewall deterioration simply from time, storage conditions, and long periods of inactivity.

Proper storage helps preserve both bias-ply and radial tires. Keeping the car away from prolonged sunlight, moisture, heat, and ozone sources can reduce premature aging, and moving the vehicle occasionally can help avoid long-term flat spotting. Any tire showing bulges, deep cracks, cuts, or repeated pressure loss deserves professional inspection before road use.
