1960 Triumph Sedan & Estate Wagon Tires

The 1960 Triumph Sedan & Estate Wagon uses two 13-inch tire sizes: 560-13 in a bias-ply construction and 155R13 in a radial construction. Those are the primary fitments associated with this vehicle, so the size decision is tied closely to whether the car is staying with a traditional bias-ply setup or using the radial alternative.

Choosing between them starts with confirming the wheel setup on the car now, especially on an older vehicle that may have seen wheel changes over time. Once the wheel dimensions are verified, the next step is deciding whether period-style appearance, whitewall presentation, and traditional construction matter more than selecting a radial-format tire.

The tire fitments for the 1960 Triumph Sedan & Estate Wagon are built around a 13-inch rim diameter. Both the 560-13 bias-ply size and the 155R13 radial size use that same 13-inch wheel diameter, so rim diameter does not change between the covered tire choices.

Rim diameter is only part of the fitment picture on a vintage Triumph. Wheel width still matters, especially when comparing a narrower bias-ply application with radial alternatives, so it is worth measuring the actual wheels on the car before selecting tires and checking for any previous wheel or suspension changes.

560-13 is a vintage numeric bias-ply tire size. The 560 portion represents a nominal section width of about 5.60 inches, while the 13 identifies the wheel diameter in inches. On the 1960 Triumph Sedan & Estate Wagon, it is the traditional bias-ply fitment and a natural reference point for period-style replacement.

That older sizing format looks unfamiliar to many modern buyers because it does not use millimeter widths or an R for radial construction. It is best understood as a classic bias-ply size that should be matched carefully to wheel width, vehicle clearance, and the appearance goal for the car before moving to a modern radial equivalent.

560-13 is a bias-ply tire size on the 1960 Triumph Sedan & Estate Wagon. It uses the older numeric sizing system and appears here as the vintage bias-ply fitment, while 155R13 represents the radial-format option for the same 13-inch rim diameter.

That distinction matters because construction affects both the look of the tire and the kind of replacement choices available. A buyer keeping the car in a more traditional presentation will often focus on 560-13 whitewall bias-ply options, while anyone considering a change in construction should also verify wheel width and overall vehicle setup before switching formats.

Radial equivalents for 560-13 include 155R13, P155/75R13, and P155/70R13. In that group, 155R13 is the 80-series metric radial equivalent, P155/75R13 is the P-metric 75-series alternative, and P155/70R13 is the P-metric 70-series alternative.

Each of those sizes belongs to the same general replacement conversation, but they are not automatic substitutes. The recommended rim-width range for these radial equivalents is 4 to 5 inches, so wheel width, overall tire dimensions, and clearance around steering and suspension should be checked before choosing one for a conversion from the original bias-ply size.

A conversion from 560-13 bias-ply to a radial alternative such as 155R13, P155/75R13, or P155/70R13 starts with the wheels. The car still needs the correct 13-inch rim diameter, and the radial-equivalent fitment should be checked against a 4 to 5 inch recommended rim-width range.

Clearance around the fenders, suspension, and steering should be reviewed before making the change, especially on an older vehicle that may no longer be on its original wheels or ride height. It also helps to decide whether the priority is traditional appearance or a radial-format driving setup, since that affects both construction choice and sidewall style.

The first consideration is whether the car should use the 560-13 bias-ply fitment or the 155R13 radial fitment. That choice shapes everything else, including tire appearance, available brands, and the overall character of the setup, while keeping the same 13-inch rim diameter across both main size options.

After that, compare the actual wheels on the car, the rim-width requirements of the tire, and the intended use of the vehicle. A restoration-minded owner may lean toward a whitewall bias-ply presentation, while someone prioritizing a radial-format tire may focus on blackwall options from the available Michelin or Dunlop lines.

Sidewall style depends on the tire size and construction chosen for the 1960 Triumph Sedan & Estate Wagon. The available 155R13 radial products come in blackwall form, while 560-13 bias-ply choices include narrow whitewall and wide whitewall options for a more traditional appearance.

That makes sidewall selection part of the broader decision between radial and bias-ply construction, not just a cosmetic afterthought. Owners aiming for a vintage visual impression may prefer one of the whitewall bias-ply styles, while a simpler road-use or sport-oriented presentation may point toward the blackwall radial offerings.

Tire choices for the 1960 Triumph Sedan & Estate Wagon include Michelin and Dunlop in the 155R13 radial size, along with BFGoodrich and Firestone in the 560-13 bias-ply size. The available series include Michelin XAS-FF, SP Sport Aquajet, Silvertown Classic Bias Ply, and Firestone Classic Bias Ply.

Brand matters mainly because it helps define which construction, series, and sidewall styles are available in the size you want. The better approach is to start with the correct fitment and wheel compatibility, then compare how each brand’s offering supports your intended look, whether that means blackwall radial simplicity or a whitewall bias-ply presentation.

For a period-style 1960 Triumph Sedan & Estate Wagon, the 560-13 bias-ply size is the most natural starting point. It preserves the vintage numeric sizing format and opens the door to traditional whitewall treatments that suit the look many owners want from a compact British sedan or estate of this era.

The exact choice still depends on how authentic or interpretive the restoration is meant to be. If originality matters down to fine visual details, it is worth checking marque-specific references or historical vehicle documentation, while a more driver-oriented restoration may simply focus on the correct size, proper wheel match, and the preferred whitewall style.

Tire construction changes the visual character of a restored 1960 Triumph Sedan & Estate Wagon more than many owners expect. The 560-13 bias-ply fitment carries a more traditional vintage presentation, especially with narrow or wide whitewall options, while the 155R13 radial choices are blackwall tires with a more modern visual impression.

That means construction is not only a driving-choice issue but also a restoration decision. A buyer trying to preserve an earlier road-car look will usually focus on the bias-ply format first, while someone comfortable with a less traditional appearance may prefer the radial route as long as the wheel dimensions and fitment details are confirmed.

Modifications can affect tire fitment on a 1960 Triumph Sedan & Estate Wagon even when the nominal tire size seems correct. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body modifications can all influence whether a 560-13 or 155R13 setup has adequate clearance.

That is especially important on an older car that may have changed hands several times. Measuring the actual wheel diameter and width, then checking steering and fender clearance at full range of motion, helps prevent fitment surprises before selecting either a bias-ply tire or a radial alternative for road use.

Before driving a 1960 Triumph Sedan & Estate Wagon on new tires, inspect the wheels for correct diameter, visible damage, and secure mounting surfaces. The rest of the basic check should include valve stems, lug hardware, suspension condition, and enough clearance around the tire at the fenders and steering components.

A collector car also benefits from a broader walk-around before any serious road use. Set tire pressure carefully, confirm there is no rubbing at full steering lock, and look over the brake, steering, and suspension systems so the car is ready to make proper use of the new 13-inch tire fitment.

Tires on a collector 1960 Triumph Sedan & Estate Wagon should be inspected regularly for air loss, uneven wear, cracking, bulges, cuts, and any signs of age-related deterioration. Low-use vintage cars often accumulate time faster than mileage, so condition matters as much as tread depth whether the car wears 560-13 bias-ply tires or 155R13 radials.

Storage also plays a major role in tire life. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and checking pressure before each outing is a smart habit. A careful inspection before longer drives is especially worthwhile on collector vehicles that spend much of their time parked.
