Triumph Sedan & Estate Wagon Tires

Triumph Sedan & Estate Wagon fitment for 1959 and 1960 includes two sizes: 155R13 and 560-13. Both sizes use a 13-inch rim diameter, but they are not the same type of tire. The 155R13 options are radial tires, while the 560-13 options are bias-ply tires. That means the choice is not only about size, but also about construction and the wheel width range the tire is intended to fit.

Owners should match the tire to the car's current wheel setup and restoration goal. A car meant to retain a more original bias-ply look may suit 560-13, while a car intended for more modern road behavior may be better matched to 155R13. Checking the wheel width stamped on the rim or verifying against known wheel specifications is the best next step before choosing between the two.

On a Triumph Sedan & Estate Wagon, 560-13 is an older numeric bias-ply size. The 560 is the nominal section width in inches with the decimal omitted, and the 13 is the wheel diameter in inches. In the available products for this size, the tires are bias-ply construction and fit 13-inch rims, with wheel fitment ranges centered around narrower original-style wheels than the radial alternatives.

That matters because 560-13 is usually chosen by owners who want period-correct stance, appearance, and steering character. It is not simply another way of writing 155R13. If the car still carries its original narrow wheels or is being restored in factory-style trim, 560-13 is often the more historically appropriate direction, and a tube is required with these bias-ply offerings.

A 1959 Triumph Sedan & Estate Wagon has 2 tire sizes listed because the fitment split is by tire construction rather than by wheel diameter. Both 155R13 and 560-13 fit 13-inch wheels, but 155R13 is a radial format and 560-13 is a numeric bias-ply format. The available products also reflect different wheel width ranges, which shows that the two sizes suit different setups even within the same model year.

The practical takeaway is that year alone does not settle the choice. Look at the wheels currently on the car, the type of tires previously fitted, and the restoration goal. A preserved or judged car may favor bias-ply sizing and whitewall style, while a regularly driven car may point toward radial construction if the wheel width is appropriate for the radial products offered.

Triumph Sedan & Estate Wagon fitment with 560-13 bias-ply tires requires inner tubes. That requirement follows the construction and style of the available 560-13 products, which are bias-ply tires intended for original-style fitment. The 155R13 radial products are listed in radial form and are treated differently from the bias-ply offerings, so the tube requirement applies specifically to the 560-13 bias-ply side of this fitment range.

If you are restoring the car on 560-13 tires, include tubes as part of the tire plan rather than treating them as an afterthought. Tube fitment should match the tire size and rim condition, and the inside of the wheel should be clean and smooth before installation. That is especially important on collector cars that may still wear older wheels with corrosion, paint buildup, or irregular bead surfaces.

Triumph Sedan & Estate Wagon owners can choose between bias-ply 560-13 tires and radial 155R13 tires within the listed fitment range for 1959 and 1960. Bias-ply tires preserve a more period-correct appearance and feel, while radial tires reflect a later construction style that generally suits owners who want more modern road behavior. Both use 13-inch rims, but the available products are intended for different wheel width ranges.

The right choice depends on how the car will be used and how faithfully it is being restored. A show-focused or factory-style presentation often points toward bias-ply, especially with whitewall styling. A driver-oriented car may benefit from radial construction if the wheels are suitable. It is worth deciding first whether authenticity or road comfort is the priority, then matching the tire and wheel as a set.

Yes, radial tires can change how a Triumph Sedan & Estate Wagon feels on the road compared with bias-ply tires. The listed 155R13 radial options and 560-13 bias-ply options represent different tire constructions, and that usually affects steering response, tracking, ride behavior, and the way the car settles in corners. Even though both fit 13-inch rims, they do not deliver the same driving character.

Owners who switch from bias-ply to radial should expect the car to feel different rather than simply newer. That change can be welcome on a regularly driven car, but it may move the experience away from period character. Before making the change, confirm that the wheel width matches the radial tire's requirements and consider whether the suspension, alignment, and overall setup are meant to preserve original behavior or improve everyday drivability.

Mixing bias-ply and radial tires on a Triumph Sedan & Estate Wagon is not a good practice. The two listed sizes for 1959 and 1960 use different constructions, and those constructions react differently under braking, cornering, and road crown changes. A car fitted with both types at once can behave unpredictably because the front and rear tires do not flex and track in the same way.

The best approach is to fit one construction type consistently across the full car. If you want a period-correct setup, stay with a full set of 560-13 bias-ply tires. If you want radial manners, fit a full set of 155R13 radials on wheels that match the specified width range. Keeping all four tires matched in size family and construction gives the most stable and understandable handling on a collector car.

A 1960 Triumph Sedan & Estate Wagon can use either 155R13 radial tires or 560-13 bias-ply tires, so the first step is confirming how the car is currently configured. Both sizes fit 13-inch wheels, but the listed products show different wheel width ranges and different construction types. That means the correct choice depends on the actual rim width, the tire type the car is meant to run, and whether originality or modern driving manners is the main goal.

Start by measuring or verifying the wheel width, then compare it to the tire's stated rim width range. Next, look at the car's restoration direction: narrow original-style wheels and vintage presentation usually point toward 560-13, while a more road-oriented setup may support 155R13. If the car came to you already fitted with one type, do not assume it is correct until the wheel width and overall fitment are checked together.

Triumph Sedan & Estate Wagon tires are available in blackwall, narrow whitewall, and wide whitewall styles within the listed fitment range. The 155R13 radial options are blackwall tires, while the 560-13 bias-ply options include both a 1.00-inch narrow whitewall and 2.25-inch wide whitewall choices. That gives owners a clear split between a more modern understated radial look and more overtly period-styled bias-ply whitewall presentation.

Choosing the sidewall style should follow the overall character of the car rather than trend alone. Blackwall radial tires usually suit a more functional driver presentation, especially on compact European cars. Whitewall bias-ply tires can be appropriate when the goal is a stronger late-1950s to early-1960s collector look. The important step is to decide style only after the correct construction type and wheel width have been settled.

Triumph Sedan & Estate Wagon tires in the listed sizes come from Michelin, Dunlop, BFGoodrich, and Firestone. Michelin and Dunlop cover the 155R13 radial size, while BFGoodrich and Firestone cover the 560-13 bias-ply size. Those brand choices also align with the construction split, so the brand decision is tied closely to whether the car is being fitted with radial or bias-ply tires.

That means owners should narrow the fitment type first and the brand second. If the car needs 13-inch radial fitment, the selection sits within the Michelin and Dunlop offerings. If the car is staying with period-style bias-ply fitment, BFGoodrich and Firestone are the relevant options. Once the size family is settled, sidewall style and visual authenticity usually become the deciding factors between brands.

Triumph Sedan & Estate Wagon tires are offered in Michelin XAS-FF, SP Sport Aquajet, Silvertown Classic Bias Ply, and Firestone Classic Bias Ply series. Michelin XAS-FF and SP Sport Aquajet are radial series in the 155R13 fitment, while Silvertown Classic Bias Ply and Firestone Classic Bias Ply are bias-ply series in the 560-13 fitment. The biggest difference between these series is construction type, followed by sidewall presentation and the wheel width range each product is intended to suit.

For a buyer, that means the series name is most useful after the basic fitment decision has been made. Choose between radial and bias-ply first, then compare the series within that construction family. Radial series will generally suit a driver-oriented setup, while the classic bias-ply series better support period-correct appearance. Sidewall style can then help refine the final choice if the car is being restored to a specific visual era.

A Triumph Sedan & Estate Wagon should be stored on a clean, dry surface away from direct sunlight, ozone sources, and major temperature swings. Tires age from time, heat, and environmental exposure even when the car is not being driven much. On a collector car, long static periods can also encourage flat spotting and place constant stress on one part of the casing, especially with bias-ply tires.

For longer storage, keep the tires properly inflated and move the car periodically so the same section is not carrying the load month after month. If the car will sit for an extended period, some owners use cradles or take weight off the tires with careful support under the chassis or suspension points. The goal is to protect both the tire shape and the wheel-and-tire assembly from avoidable aging stress.

Tires on a Triumph Sedan & Estate Wagon should be inspected regularly, not just at annual service time. Collector cars often cover few miles, so age-related issues can appear before tread wear becomes meaningful. Sidewall cracking, tread separation, tube-related problems on bias-ply fitments, uneven wear, and changes in air retention are all more important than mileage alone on a lightly used vintage car.

A good routine is to inspect the tires before each meaningful drive and to give them a closer check several times a year. Look for visible cracking, bulges, cuts, and signs of bead or valve stem trouble, and confirm inflation before the car goes on the road. If the car has sat through a season or longer, a closer inspection is wise before resuming regular use.

Tires on a Triumph Sedan & Estate Wagon should be replaced when age, cracking, hardening, vibration, repeated air loss, or structural concerns appear, even if the tread still looks deep. Collector-car tires often age out before they wear out. That is especially true on lightly driven cars, where appearance can be misleading and the internal condition of the casing may no longer match what the tread suggests.

The practical rule is to judge the tire as a whole assembly, not by tread depth alone. If the car has older bias-ply tires, tube-related service history should also be considered because tube and casing age work together. A specialist inspection is worthwhile whenever the tire's age is uncertain or the car has been inactive for long periods, since quiet deterioration can go unnoticed until the car is back on the road.

Triumph Sedan & Estate Wagon fitment within the listed years includes both 560-13 bias-ply tires and 155R13 radial tires. That tells you the model family can be associated with either an older numeric bias-ply approach or a radial metric approach in 1959 and 1960. The available series and sidewall styles show that more than one restoration direction is possible depending on how a specific car was delivered or later configured.

For an originality-focused restoration, the next step is to compare the car against factory literature, surviving examples, or a marque specialist rather than choosing by size alone. Wheel width, sidewall treatment, and whether the car should present as a bias-ply or radial-era setup all matter to authenticity. The tire should support the specific car's history, not just the broad model-year range.

Yes, correct tire fitment can affect both the presentation and the judged authenticity of a Triumph Sedan & Estate Wagon. Size family, construction type, sidewall style, and overall stance all influence whether the car looks consistent with its period. A radial blackwall and a bias-ply whitewall can create very different impressions, even though both may fit within the listed range for 1959 and 1960.

For owners concerned with value or formal judging, tire selection should be treated as part of the restoration plan rather than a final cosmetic choice. Judges and informed buyers often notice whether the tire construction and sidewall style suit the car's era and character. Marque clubs, period photography, and factory literature remain the strongest references when deciding how exact the final fitment needs to be.

Triumph Sedan & Estate Wagon restoration choices in the listed sizes include blackwall, narrow whitewall, and wide whitewall sidewall styles. Blackwall appears on the 155R13 radial options, while the 560-13 bias-ply range includes both narrow and wide whitewall versions. That means the correct look depends on whether the restoration is aiming for a restrained European presentation or a more stylized period bias-ply appearance.

The best choice is the one that matches the car's intended historical character and wheel setup. A conservative restoration may lean toward blackwalls, especially where radial fitment is being used. A more period-styled bias-ply presentation may suit narrow or wide whitewalls, depending on the exact look being recreated. Studying period images of similarly configured cars can help settle the visual question once size and construction are already correct.

A properly selected and properly maintained set of tires can be suitable for driving a Triumph Sedan & Estate Wagon on public roads, but safety depends on matching the tire to the wheel and using a complete, healthy set. The listed fitments include both radial and bias-ply constructions, and each brings different handling characteristics. Safety also depends on tire age, condition, inflation, and the overall mechanical state of the car.

The most important practical step is to treat tire choice as part of the full chassis setup. Old steering components, weak dampers, poor alignment, or mixed tire constructions can undermine even a correct nominal size. Before regular road use, make sure the car is mechanically sorted and that all four tires are matched in construction type, correctly fitted to the wheels, and free of visible age-related defects.

Before driving a Triumph Sedan & Estate Wagon, check tire pressure, visible sidewall condition, tread condition, and any signs of cracking, bulging, or impact damage. On 560-13 bias-ply fitments, tube condition and valve stem health are also important because a tube-related issue can show up as slow leakage or sudden air loss. Wheel hardware and general tire-to-fender clearance should also be reviewed on a car that has sat for long periods.

That pre-drive check should be paired with a quick assessment of the car's steering, brakes, and suspension, since tire safety is tied closely to the rest of the chassis. If the car feels different from its last outing, do not assume the issue is minor. A collector car that sees infrequent use can develop problems while parked, and the tires are often the first place those problems reveal themselves.

A sensible speed for a Triumph Sedan & Estate Wagon on original-style tires is one that respects the age of the car, the condition of the tires, and the behavior of the chosen construction type. Bias-ply 560-13 tires and radial 155R13 tires will not feel the same at speed, and a restored car on narrow original-style wheels should not be driven as though it were a modern compact. Tire condition matters as much as nominal size.

The practical approach is to build speed gradually and let the car tell you what is comfortable and stable, rather than chasing modern traffic pace. Fresh, properly fitted tires on a well-sorted chassis can make road use much more confidence-inspiring, but collector-car margins remain different from modern vehicles. If there is any vibration, wandering, or heat buildup, slow down and inspect the car before continuing.
