1960 Triumph Sedan Tires

The 1960 Triumph Sedan uses two primary tire sizes: 520-13 in bias-ply construction and 145R13 in radial construction. Both sizes are built for 13-inch rims, but they represent different tire formats and different approaches to how the car is set up for appearance and road use.

The practical choice starts with confirming what is already on the car and whether the wheel width suits the tire being considered. A restoration-minded owner may stay with 520-13, while a buyer looking for a classic small-car radial may focus on 145R13 or a radial equivalent tied to the 520-13 size.

The tire sizes used on a 1960 Triumph Sedan are both built around a 13-inch rim diameter. That applies to the 145R13 radial option and the 520-13 bias-ply option, so rim diameter itself stays consistent even though the tire constructions and sizing systems differ.

Wheel diameter is only one part of fitment, so the next check is wheel width and the car's actual setup. Some available products in these sizes call for relatively narrow rims, and any car with changed wheels or earlier replacements should be measured before a new set is chosen.

The 1960 Triumph Sedan Base falls within the same fitment pattern as the model overall, using either 145R13 radial tires or 520-13 bias-ply tires. The difference is not a separate sub-model-only size, but the construction and style direction chosen for the car.

That makes the buying decision more about setup than trim level. A Base model kept in a traditional presentation may lean toward 520-13 with blackwall or whitewall styling, while a car already running radial construction should have its wheel width and overall tire dimensions checked before staying with 145R13 or considering a radial alternative.

520-13 is the bias-ply tire size used on the 1960 Triumph Sedan. It is a vintage numeric bias-ply format, and it differs from the 145R13 radial size by both construction and the way the tire size is expressed.

Keeping 520-13 maintains a more traditional tire presentation, especially when paired with blackwall, narrow whitewall, or wide whitewall styling. Moving away from it toward a radial alternative changes more than the label on the sidewall, so wheel width, overall dimensions, and clearance should be reviewed before changing construction.

Radial equivalents for 520-13 include 155R13 as an 80-series metric radial, P155/75R13 as a P-metric 75-series radial, and P155/70R13 as a P-metric 70-series radial. These are alternative radial formats associated with the original 520-13 size rather than additional primary factory-size listings.

Each equivalent should be evaluated in the context of the car's wheel width and available space around the tire. A 4- to 5-inch rim width range is associated with these radial equivalents, and a sensible conversion check also includes wheel condition, suspension clearance, and the car's intended driving use.

A conversion from 520-13 bias-ply to a radial setup on a 1960 Triumph Sedan starts with confirming wheel diameter, wheel width, and the exact radial size being considered. The recognized radial alternatives include 155R13, P155/75R13, and P155/70R13, each of which should be treated as an alternative size choice rather than an automatic swap.

The next step is checking clearance at the fenders and steering range, along with the condition of suspension and steering components. Collector cars often have replacement wheels or long-standing alignment issues, so it is wise to verify the complete setup before changing construction and expecting the car to behave the same way on the road.

Start with the correct primary size and construction for the car's current setup: 520-13 for bias-ply or 145R13 for radial. From there, compare wheel compatibility, the intended appearance, and whether the car is being kept close to a traditional period-style presentation or used with a more modern radial approach.

Product differences also matter. Some tires are offered only as blackwalls, while others bring narrow whitewall or wide whitewall styling, and rim-width specifications vary across certain products. Looking at the full combination of size, construction, sidewall treatment, and wheel fitment leads to a smarter choice than selecting by appearance alone.

1960 Triumph Sedan tire options include blackwall, narrow whitewall, and wide whitewall sidewall styles. Blackwall choices appear in both 145R13 radial and 520-13 bias-ply offerings, while whitewall treatments are concentrated in the 520-13 bias-ply selections.

That gives the car owner some flexibility in presentation, especially if the goal is a more understated British sedan look or a more decorative restoration-oriented finish. Sidewall style should still be chosen after the correct size and construction are settled, since appearance cannot override wheel compatibility or the tire format that suits the car.

Tires for the 1960 Triumph Sedan are available from Michelin, Firestone, and Premium Sport. Michelin and Firestone appear in the 145R13 radial category, while Firestone and Premium Sport cover the 520-13 bias-ply category with several different styling approaches.

Brand choice should be considered alongside tire series, construction, and sidewall treatment rather than in isolation. A buyer comparing products in this size range will usually get more value from checking whether the tire matches the car's wheel dimensions and intended look than from treating the brand name as the only decision point.

For a period-style 1960 Triumph Sedan, 520-13 bias-ply is the most traditional-looking starting point because it keeps the vintage numeric sizing format and bias-ply construction. Within that size, blackwall, narrow whitewall, and wide whitewall choices allow the car to be finished with a subtler or more decorative appearance.

A restoration-focused buyer should balance visual goals with how the car will actually be used. If exact originality matters, marque references and period photos are worth consulting before choosing a whitewall treatment, since a tire can look convincingly era-appropriate without automatically being the exact tire style originally delivered on the car.

Tire construction changes the character of a restored 1960 Triumph Sedan as much as the sidewall style does. A 520-13 bias-ply generally preserves a more traditional small-sedan presentation, while a 145R13 radial gives the car a later-looking metric radial identity even though it still fits the same 13-inch wheel diameter.

That visual difference matters when the car is being restored for shows, club events, or a carefully period-style street presentation. Buyers who want the stance and feel of an earlier tire format usually begin with the bias-ply route, while those prioritizing radial construction should still choose a size and sidewall style that do not overwhelm the car's proportions.

Yes, modifications can affect tire fitment on a 1960 Triumph Sedan even when the nominal tire size looks correct. Aftermarket wheels, altered wheel width, suspension changes, and body or fender work can all change how a 520-13, 145R13, or radial equivalent sits and clears the car.

That is especially important on compact vintage cars where space around the tire can be limited. Any car that has been lowered, fitted with non-stock wheels, or rebuilt over many decades should have its wheel dimensions and turning clearance checked before replacement tires are chosen simply by size code alone.

Before driving a 1960 Triumph Sedan on new tires, inspect the wheels for correct diameter and sound condition, then confirm proper inflation and look over the suspension and steering for looseness or wear. It also helps to verify that the selected tires match the car's actual wheel width and intended construction type.

A short test drive should include listening for rubbing and checking steering response and straight-line behavior. Since many collector cars spend long periods parked, it is smart to recheck air pressure after the first outing and keep an eye on any signs of interference, uneven wear, or unexpected air loss.

Tires on a collector 1960 Triumph Sedan should be maintained with regular pressure checks, visual inspection of tread and sidewalls, and periodic review for cracking, bulges, cuts, or slow air loss. That applies whether the car is running 520-13 bias-ply tires or 145R13 radial tires.

Storage habits matter just as much as mileage on a lightly used classic. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and occasional movement prevents long static periods from becoming harder on the casing than normal road use.
