1960 Hillman Minx II Tires

The 1960 Hillman Minx II uses two primary tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both sizes are built around a 15-inch rim, so the main fitment distinction is not wheel diameter but tire construction and the style of replacement being considered.

That means the first step is deciding whether the car should keep a traditional bias-ply look or move to a radial fitment. It is still worth confirming the actual wheel width on the car, especially if the Minx has been modified or has replacement wheels, since construction choice, sidewall style, and rim compatibility all affect the final decision.

The tire fitments used on a 1960 Hillman Minx II are built for a 15-inch rim. Both the 560-15 bias-ply size and the 155R15 radial size share that same rim diameter, which simplifies the basic wheel-diameter question compared with vehicles that used multiple diameters.

Rim diameter is only part of the picture, though, because wheel width still matters when comparing actual tire options. A car that still has its original-style wheels may be straightforward, but any changed wheels should be measured before choosing between bias-ply, metric radial, or bias-look radial alternatives in the same general fitment family.

560-15 is a vintage numeric bias-ply size. The 560 portion refers to an approximate 5.60-inch nominal section width, and the 15 identifies the wheel diameter in inches. On a 1960 Hillman Minx II, it represents the traditional bias-ply fitment and is available in blackwall, narrow whitewall, and wide whitewall versions.

For many owners, that size is as much an appearance decision as a fitment one, because the numeric bias-ply format carries a distinctly period-style look. It also helps explain why a modern-looking metric radial such as 155R15 can still be relevant, even though the code itself follows a completely different sizing language.

On the 1960 Hillman Minx II, 560-15 is the bias-ply tire size. It uses the older numeric sizing format and supports a traditional vintage presentation, with available options including blackwall, narrow whitewall, and wide whitewall sidewall treatments across several classic bias-ply series.

That matters because a 560-15 selection keeps the car in its period-style construction family, while 155R15 represents the radial path on the same 15-inch rim diameter. Owners comparing the two should think beyond size alone and confirm wheel width, desired ride character, and the visual effect they want from the finished car.

Two radial-equivalent choices are available for 560-15: 155R15 and 560R15. The 155R15 option is an 80-series metric radial equivalent, while 560R15 is the bias-look radial equivalent for buyers who want radial construction with a more traditional visual presentation.

Those equivalents should be treated as alternatives rather than automatic substitutes. A recommended rim-width range of 4 to 5 inches applies to the equivalent path, and the final choice should also account for the car’s actual wheels, overall tire dimensions, and steering or fender clearance before converting from bias-ply.

Start by confirming the wheel diameter and width on the car, then compare the original 560-15 bias-ply fitment with the radial alternative being considered, such as 155R15 or 560R15. The Minx II uses a 15-inch rim either way, but construction changes still need to be evaluated carefully.

A radial conversion should also be checked against tire clearance, suspension condition, steering travel, and the car’s actual ride height. The practical decision is not just whether a radial equivalent exists, but whether the wheels, stance, and intended use of the car support that change without creating unwanted fitment or appearance compromises.

Choosing a 560-15 tire for a 1960 Hillman Minx II starts with deciding what kind of vintage presentation the car should have. This size is available in bias-ply construction from brands including Firestone, US Royal, Coker Classic, and Pro-Trac, with blackwall, narrow whitewall, and wide whitewall styles represented.

After appearance, compare the actual tire series and wheel-width suitability for the wheel on the car. A restoration-minded sedan may call for a classic bias-ply sidewall treatment, while a more specialized build may lean toward a different style within the same size. Matching the tire’s character to the car matters as much as the size itself.

The available sidewall styles for 1960 Hillman Minx II tires include blackwall, narrow whitewall, and wide whitewall. The radial 155R15 choices center on blackwall designs, while the 560-15 bias-ply size adds traditional whitewall options that can shift the overall look of the car quite a bit.

That makes sidewall style one of the biggest visual decisions on this vehicle. A blackwall keeps the presentation simple and understated, while narrow or wide whitewalls push the car toward a more restoration-oriented appearance. The right choice depends on the trim presentation of the vehicle and how period-styled the finished car is meant to look.

Tires for the 1960 Hillman Minx II are available from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Those brands cover both main fitment paths, with radial choices in 155R15 and bias-ply choices in 560-15, along with several different tire series and sidewall treatments.

Brand choice is best handled as part of a broader comparison rather than as a shortcut to the answer. Start with the correct size and construction, then narrow the field by sidewall style, tire series, and wheel-width suitability. That approach keeps the selection tied to the car’s needs instead of reducing the decision to name recognition alone.

For a period-style 1960 Hillman Minx II, the 560-15 bias-ply fitment is the natural starting point because it preserves the vintage numeric size format and traditional construction. Within that size, blackwall, narrow whitewall, and wide whitewall choices allow the car to lean toward a simpler or more dressed-up mid-century look.

The right answer depends on how exact the restoration goal is. A buyer focused on broadly authentic visual character may stay with bias-ply, while someone balancing vintage appearance with radial construction may also consider the 560R15 bias-look radial. If originality matters at a very detailed level, marque-specific historical references are worth checking.

Tire construction changes the visual character of a restored 1960 Hillman Minx II more than many owners expect. A 560-15 bias-ply keeps the car in a traditional vintage format, while a 155R15 radial introduces a more modern metric sizing convention and a different overall presentation even though the rim diameter stays at 15 inches.

That distinction matters when the goal is a cohesive restoration rather than simple roadworthiness. Whitewall bias-ply options can emphasize the car’s period styling, while blackwall radials give it a cleaner, more contemporary road-use look. Construction choice should match the story the finished car is meant to tell, not just the wheel it mounts on.

Yes, modifications can affect tire fitment on a 1960 Hillman Minx II even when the tire size itself is correct. Aftermarket wheels, altered wheel width, changed offset, suspension work, or a lowered stance can all influence how a 560-15 or 155R15 tire sits in the wheel opening and clears surrounding components.

A Minx II that no longer has its original-style wheel and suspension setup should be measured before tires are selected. Checking wheel width, steering clearance, fender clearance, and the tire’s overall relationship to the car helps avoid choosing a size or construction that looks right on paper but creates problems once installed.

Before driving a 1960 Hillman Minx II on new tires, inspect the wheels for damage, verify that the tire size matches the intended 15-inch fitment, and make sure inflation is set appropriately for the tire being used. It is also smart to look over suspension and steering components on a collector-era car before any real road use.

A new tire cannot compensate for worn hardware or poor wheel condition. After installation, recheck for any contact during full steering travel and pay attention to how the car tracks and brakes at moderate speeds. Early inspection of pressure retention, valve condition, and clearance helps catch small issues before they become roadside problems.

Collector-car tires on a 1960 Hillman Minx II should be inspected regularly for cracking, cuts, bulges, irregular wear, and slow air loss, whether the car runs 560-15 bias-ply tires or 155R15 radials. Cars that are driven infrequently deserve extra attention because age and storage conditions can matter as much as tread depth.

Pressure checks should be routine, and the car should be stored away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment when possible. Occasional movement helps avoid long-term flat spotting during storage, and any tire that shows visible deterioration should be evaluated before the Minx returns to normal road use.
