1959 Hillman Minx II Tires

The 1959 Hillman Minx II uses two primary tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both sizes are tied to a 15-inch rim, so the main distinction is not wheel diameter but the tire's construction, sizing system, and overall character.

Choosing between them starts with the car's current wheel setup and the result you want. A 560-15 suits a traditional vintage presentation, while 155R15 is the radial-format option for the same rim diameter. On a car that has been modified over the years, it is wise to confirm actual wheel width and clearance before settling on either size.

The 1959 Hillman Minx II uses a 15-inch rim diameter with both of its primary tire sizes. That applies whether the car is wearing a 560-15 bias-ply tire or a 155R15 radial, so the shared fitment point is the 15-inch wheel diameter.

Rim diameter is only the first part of the check. Wheel width still matters, especially when comparing a traditional bias-ply setup with a radial or radial-equivalent alternative. A car that still has original-type wheels may point you one direction, while later replacement wheels or aftermarket rims can change which tire choice is the more appropriate match.

The 1959 Hillman Minx II Special uses the same two fitment paths found for this model core: 560-15 in bias-ply construction and 155R15 in radial construction. Both remain 15-inch tire choices, so the sub-model does not introduce a different rim diameter.

That makes selection easier, but the decision still matters because the two sizes represent different tire constructions and different visual results. A Special kept in a restoration-oriented configuration may lead an owner toward 560-15, while a car set up for more regular road use may be evaluated around 155R15 or another confirmed radial-equivalent approach.

On the 1959 Hillman Minx II, 560-15 is the numeric bias-ply tire size. It uses the older inch-based sizing convention and represents the traditional construction choice for this car, distinct from the 155R15 radial fitment that also appears on the same 15-inch wheel diameter.

That distinction matters because bias-ply and radial tires do not present the same way on the car and do not deliver the same ownership experience. Owners keeping a period-style look often stay with 560-15, while anyone considering a conversion should confirm wheel width, suspension condition, and clearance instead of assuming every 15-inch wheel setup will behave the same.

The 560-15 bias-ply size has two stated radial equivalents for the 1959 Hillman Minx II: 155R15 and 560R15. The 155R15 is the 80-series metric radial equivalent, while 560R15 is the bias-look radial equivalent for owners who want radial construction with a more traditional visual style.

Those options should be treated as alternatives, not automatic substitutions. A recommended rim width range of 4 to 5 inches is associated with the equivalent fitment path, and wheel compatibility, overall tire dimensions, and available clearance should be checked carefully. That is especially important on a car with replacement wheels, suspension work, or any change from its original stance.

The right choice depends on how the 1959 Hillman Minx II is being used and how closely the owner wants to preserve a vintage tire presentation. A 560-15 bias-ply tire keeps the car in a traditional sizing and construction format, while 155R15 moves it into a radial format on the same 15-inch rim diameter.

Appearance goals often drive the decision just as much as road manners. A restoration-minded owner may prefer the visual character of a bias-ply tire, while a driver focused on regular touring may lean toward a radial or bias-look radial alternative. Either route deserves a wheel-width and clearance check before the final choice is made.

Start with the size and construction that match the car's intended setup. The 1959 Hillman Minx II uses 560-15 for a traditional bias-ply path and 155R15 for a radial path, both on 15-inch rims. That means the first decision is less about wheel diameter and more about construction, appearance, and how the car will be driven.

After that, compare the available product details that actually affect your choice, including rim-width compatibility, sidewall treatment, tire series, weight, and load figures where stated. A lightly used show car and a regularly driven collector car may not lead to the same answer. The best match is the one that suits the car's wheels, use, and visual goals.

Sidewall choice depends on which size and construction you choose for the 1959 Hillman Minx II. The 155R15 radial options are offered as blackwalls, while the 560-15 bias-ply range includes blackwall, narrow whitewall, and wide whitewall styles. That gives the bias-ply fitment a noticeably broader appearance range.

The practical effect is that sidewall style can become part of the construction decision, not just a finishing touch. Whitewall bias-ply tires can push the car toward a stronger period-style look, while blackwall radials keep the presentation simpler and more understated. Matching the sidewall to the car's trim, wheel covers, and restoration direction usually produces the most satisfying result.

The 1959 Hillman Minx II has tire options from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Brand availability depends on the size and construction you are considering, with the 155R15 radial fitment drawing from Firestone, Michelin, Avon, and Vredestein, while 560-15 bias-ply choices include Firestone, US Royal, Coker Classic, and Pro-Trac.

Brand alone should not make the decision. It helps more to compare which series, sidewall styles, and specifications each brand offers in the size you actually plan to run. Once the construction choice is settled, the field narrows naturally and the remaining decision becomes one of appearance, rim compatibility, and the kind of use the car will see.

For a period-style 1959 Hillman Minx II, the 560-15 bias-ply size is the most natural starting point because it preserves the vintage numeric sizing format and traditional construction. Within that size, blackwall, narrow whitewall, and wide whitewall options create different visual effects without moving away from the bias-ply presentation.

The best appearance choice depends on how closely the car is being restored and what visual statement you want the tires to make. Owners pursuing exact historical accuracy should compare their selection against marque references, period photos, or restoration records for the specific car. For many buyers, the goal is not exact originality but a convincing and well-proportioned period look.

Tire construction changes the visual character of a restored 1959 Hillman Minx II more than many owners expect. A 560-15 bias-ply tire maintains a traditional vintage look, while a 155R15 radial introduces a more modern tire format even though it stays on the same 15-inch rim diameter.

That difference shows up in the overall presentation of the car, especially when wheel covers, trim, and ride stance are part of the restoration plan. Sidewall treatment matters as well, since the bias-ply choices include whitewall options that can shift the personality of the car significantly. Construction is therefore both a mechanical choice and an appearance decision.

Yes, modifications can affect tire fitment on a 1959 Hillman Minx II even when the car is using one of its known 15-inch tire sizes. Changes such as aftermarket wheels, altered wheel width, suspension work, lowering, or body repairs can all influence how a 560-15 bias-ply or 155R15 radial sits and clears the car.

That is why the actual wheel and vehicle setup should be checked before finalizing a tire choice. Clearance at the fender, steering range, and suspension travel all matter, especially when moving from bias-ply to radial or trying a radial-equivalent option. A collector car that has changed hands over decades may no longer match its original wheel specification.

Before driving a 1959 Hillman Minx II on new tires, inspect the wheels, valve stems, and overall wheel condition, then confirm that the tires are seated properly and inflated for the setup being used. It is also smart to look at steering and suspension components, since worn parts can affect how a fresh set of tires behaves on the road.

A short shakedown drive should include checking for rubbing, unusual vibration, pull, or uneven contact after the first miles. Collector vehicles that sit for long periods deserve extra attention because stale suspension bushings, loose wheel hardware, or neglected alignment can spoil the result. New tires perform best when the surrounding mechanical condition is equally sound.

Collector-car tires on a 1959 Hillman Minx II should be maintained with regular pressure checks, visual inspections, and careful storage habits. Whether the car is running 560-15 bias-ply tires or 155R15 radials, owners should watch for cracking, cuts, bulges, uneven wear, and slow air loss, especially on a vehicle that spends long stretches parked.

Storage conditions matter almost as much as mileage. Keeping the car away from prolonged sunlight, moisture, excess heat, and ozone sources helps protect the rubber over time. A tire that still shows usable tread can still be unsuitable if age or storage damage has compromised it, so periodic hands-on inspection is a routine part of safe collector-car ownership.
