1955 Simca Aronde Tires

A 1955 Simca Aronde uses two primary tire sizes: 155R14 in radial construction and 560-14 in bias-ply construction. Both sizes are built for a 14-inch rim, so the decision is not wheel diameter alone but also whether the car is being kept in a traditional bias-ply format or set up with a radial tire.

Choosing between them starts with confirming what wheels are actually on the car now. Many collector cars have been changed over the years, so wheel width, tire clearance, and the owner’s goal for appearance and road use should all be checked before treating one construction as the automatic choice.

The 1955 Simca Aronde uses a 14-inch rim with both of its primary tire sizes. That applies to the 155R14 radial and the 560-14 bias-ply fitment, so rim diameter stays consistent even though the tire construction and sizing format change.

Diameter is only the first part of the wheel question. A bias-ply 560-14 and a radial 155R14 can have different rim-width expectations, so it is worth measuring the actual wheel before choosing a tire, especially if the car has replacement steel wheels or an older radial conversion already in place.

The 1955 Simca Aronde 55 & Coupe follows the same fitment pattern, with 155R14 offered as the radial size and 560-14 offered as the bias-ply size. In practical terms, that means the sub-model does not introduce a separate wheel diameter or a different primary size family.

The more important step is identifying which setup the individual car is using today. A buyer looking for a period-style restoration approach may stay with 560-14, while a driver-oriented car may be using 155R14, so wheel width and the current tire construction should be confirmed before replacement.

560-14 is the bias-ply tire size for the 1955 Simca Aronde. It uses the older numeric sizing system common to mid-century vehicles, and it is the traditional-looking option among the two primary sizes used on this model.

That matters because replacing a 560-14 tire is not only about matching rim diameter. Bias-ply construction affects the car’s period presentation and may also influence the overall feel compared with a radial-equipped setup, so the wheel width, current suspension condition, and restoration goals should all be considered before changing formats.

Both approaches are valid on a 1955 Simca Aronde because the car uses 560-14 in bias-ply form and 155R14 in radial form. The bias-ply size leans toward a more traditional presentation, while the radial size gives the owner a fitment path in a later tire construction on the same 14-inch rim diameter.

The right choice depends on how the car is used and how closely its appearance is being preserved. A radial conversion should never be assumed from size alone, so the wheel width, tire-to-body clearance, and the condition of steering and suspension components deserve a careful look before switching constructions.

A 1955 Simca Aronde moving from 560-14 bias-ply to 155R14 radial should be checked for wheel width, wheel condition, and basic clearance at the fenders and steering components. Both use a 14-inch rim, but that shared diameter does not make the conversion automatic.

Collector cars often carry older replacement wheels, worn suspension parts, or alignment issues that were hidden by the previous tires. Looking closely at steering travel, ride height, tire-to-body space, and the condition of bushings and shocks helps prevent choosing a radial size that works on paper but creates problems in real use.

Start with the correct size and construction for the way the car is being kept. A 1955 Simca Aronde uses either 560-14 in bias-ply form or 155R14 in radial form, so the first decision is whether the goal is a traditional period-style look or a radial-equipped road car.

After that, compare the details that affect actual use and presentation. Wheel width, sidewall style, tire series, and basic load and pressure specifications can all matter, and those points become especially important when the car has older replacement wheels or when the owner wants the tire’s appearance to support a restoration-minded finish.

The sidewall choices for a 1955 Simca Aronde depend on the size and construction selected. In 560-14 bias-ply form, available styles include blackwall, narrow whitewall, and wide whitewall, while the 155R14 radial options are offered as blackwall tires.

That makes sidewall selection an appearance decision as much as a fitment one. A whitewall can push the car toward a more restoration-oriented presentation, while a blackwall keeps the look simpler, so it helps to decide early whether visual character or construction choice is the main priority for the finished car.

The 1955 Simca Aronde has tire options from Michelin, Firestone, and BFGoodrich. Michelin and Firestone cover the 155R14 radial fitment, while BFGoodrich covers the 560-14 bias-ply fitment through the Silvertown Classic Bias Ply series.

Brand choice should be considered alongside construction and style rather than by name alone. Since the product groups split between radial blackwalls and bias-ply blackwall or whitewall designs, the more useful comparison is which brand supports the right size, wheel-width range, and visual direction for the specific Aronde being serviced.

For a period-style 1955 Simca Aronde, the 560-14 bias-ply size is the natural starting point. Its vintage numeric sizing format and available blackwall, narrow whitewall, and wide whitewall versions suit a more traditional mid-1950s presentation than the later-style radial format.

The final choice depends on how authentic-looking the finished car needs to be. Owners pursuing exact historical accuracy should compare their tire selection with marque references, photos, or restoration documentation, while those aiming for a visually appropriate road car can focus on the sidewall treatment that best matches the Aronde’s overall character.

Tire construction changes the visual impression of a restored 1955 Simca Aronde as much as it changes the fitment path. A 560-14 bias-ply tire keeps the car in a traditional small-car format, while a 155R14 radial introduces a more modern tire style even though the rim diameter remains 14 inches.

That difference becomes more noticeable once sidewall treatment is considered. A blackwall radial tends to give a cleaner later look, while bias-ply blackwall or whitewall versions can better support a restoration-oriented presentation, so construction choice should be made with the car’s finished stance and trim character in mind.

Yes, modifications can affect tire fitment on a 1955 Simca Aronde even when the replacement tire stays within the known 14-inch fitment family. Changes such as aftermarket wheels, altered ride height, brake upgrades, or body repairs can influence the space available for either a 560-14 bias-ply or a 155R14 radial.

A modified car should be checked at full steering lock and through normal suspension movement before a tire is chosen. Wheel width and the tire’s relationship to the fender edge, inner wheelhouse, and suspension hardware matter more once the original setup has been changed from stock-era dimensions.

Before putting a 1955 Simca Aronde back on the road with new tires, inspect the wheels for damage or heavy corrosion and make sure the tire size matches the intended setup. It also helps to check valve stems, basic alignment condition, and whether the car has enough clearance through steering travel and normal suspension movement.

Road readiness goes beyond the new tires themselves. Sidewall rubbing marks, loose wheel bearings, worn tie-rod ends, weak shocks, and brake issues can all affect how the car behaves after installation, so a brief mechanical review is worthwhile before relying on a collector-era vehicle for regular driving.

Tires on a collector 1955 Simca Aronde should be checked regularly for air loss, tread wear, cracking, bulges, and cuts, even if the car is driven only occasionally. Low-use vintage cars often age their tires by time and storage conditions rather than by mileage alone.

Keeping the car in a cool, dry space and away from prolonged sunlight helps preserve tire condition. Periodic pressure checks, visual inspections after long storage, and occasional movement to avoid long-term flat spotting are sensible habits whether the Aronde is running 560-14 bias-ply tires or 155R14 radial tires.
