1958 Simca Vedette Tires

The 1958 Simca Vedette uses two primary tire sizes: 165-15 in bias-ply construction and 165R15 in radial construction. Both sizes are associated with a 15-inch rim, so the main difference is not wheel diameter but the tire's sizing system and construction type.

That means the first decision is whether the car is being kept with a traditional bias-ply setup or moved to a radial setup. A Vedette that already has radial-friendly wheel and suspension preferences may point you toward 165R15, while a restoration-oriented car may stay with 165-15. It is still worth confirming actual wheel width and overall clearance before final selection.

The 1958 Simca Vedette uses a 15-inch rim with both of its primary tire fitments. That applies whether the car is wearing the 165-15 bias-ply size or the 165R15 radial size, so rim diameter stays consistent across the covered fitment choices.

Rim diameter is only part of the fitment picture, especially if the car has changed wheels at some point in its life. Wheel width still matters when comparing available tires, particularly among the 165R15 radial products where rim-width allowances vary. Measuring the actual wheel before ordering is a smart step on a collector car with an uncertain wheel history.

Yes. The 1958 Simca Vedette Base follows the same covered fitment pattern as the model overall, using either a 165-15 bias-ply tire or a 165R15 radial tire on a 15-inch rim. There is no separate sub-model tire size split within the Base listing here.

That keeps selection focused on construction and tire style rather than trim-specific sizing differences. The more useful question for a Base owner is whether the car should keep its traditional bias-ply presentation or move into the broader radial offerings available in 165R15. Wheel width, steering clearance, and the car's restoration goals should guide that decision.

On the 1958 Simca Vedette, 165-15 is the bias-ply fitment. It uses a vintage numeric bias-ply size format and represents the traditional construction choice for owners who want to preserve an earlier tire look and feel on the car's 15-inch wheel diameter.

That distinction matters because 165R15 is also used on the same car, but it is a radial and not just another way of writing the same size. Choosing between them affects how the Vedette presents visually and how closely the setup follows a period-style approach. Before changing construction, confirm wheel width and clearance rather than assuming the two formats behave identically.

Radial equivalents for 165-15 include 165R15 as the 80-series metric radial option, P165/75R15 as the P-metric 75-series alternative, and P175/70R15 as the P-metric 70-series alternative. These are equivalent sizing paths for the original bias-ply fitment rather than additional primary factory-style sizes.

Each option should be treated as a conversion choice, not an automatic substitute. The recommended rim-width range attached to the equivalent set is 4 to 5 inches, which makes wheel measurement especially important before moving away from the original bias-ply format. Tire section, overall dimensions, and available fender and steering clearance should also be checked on the individual car.

Start by confirming the actual wheel diameter and width on the car, then compare the intended radial size against the original 165-15 fitment. For the 1958 Simca Vedette, 165R15, P165/75R15, and P175/70R15 are the relevant radial-equivalent paths, and the equivalent rim-width guidance is 4 to 5 inches.

After the wheel is confirmed, inspect front and rear clearance with the suspension settled and the steering turned through its range. A collector car can also have alignment wear, weak springs, or old wheel repairs that affect radial conversion results. Keeping those checks separate from the size choice helps avoid treating an equivalent as though it automatically suits every Vedette setup.

Begin with the basic fitment decision: 165-15 if the car will remain bias-ply, or 165R15 if it will run a radial. From there, compare the tire's construction, sidewall style, rim-width compatibility, and how closely the tire matches the appearance and road-use goals for your particular 1958 Simca Vedette.

A lightly driven restoration may place more value on traditional presentation, while a car expected to see regular road miles may lead you toward the wider radial selection. It also helps to compare practical details such as load figures at stated pressures and the wheel-width ranges attached to individual products. Those details shape the best match without reducing the choice to brand alone.

In 165R15 radial form, the 1958 Simca Vedette has blackwall, narrow whitewall, and wide whitewall choices. That gives the car a broad appearance range, from a more understated European touring look to a brighter whitewall presentation that can shift the visual character of the car quite a bit.

Sidewall choice should support the way the Vedette is being finished rather than being treated as a purely cosmetic afterthought. A blackwall tends to keep attention on the body and wheel design, while narrow or wide whitewalls create a more dressed, period-style effect. Looking at wheel covers, paint tone, and overall restoration intent usually makes the right sidewall direction much clearer.

The 165R15 radial size for the 1958 Simca Vedette is available from Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, and Vredestein. Those brands span several classic-oriented radial series, so the comparison is not just about the brand name but also the style and specification of the individual tire.

A useful way to compare them is by grouping choices according to visual treatment and intended use. Some emphasize whitewall presentation, while others keep a blackwall look or reflect a more European-style radial character. Once the correct size and wheel width are confirmed, the strongest comparison points become sidewall design, series character, and product specifications such as stated load figures and rim-width allowances.

For a period-style 1958 Simca Vedette, the 165-15 bias-ply size is the natural starting point because it preserves the vintage sizing format and construction type associated with the car's era. That makes it especially relevant when the goal is maintaining a more traditional visual stance and overall presentation.

Some owners still prefer a 165R15 radial because it keeps a classic overall look while widening the available product and sidewall choices. The better choice depends on whether the project emphasizes historical character, regular touring use, or a careful middle ground. When strict originality matters, marque-specific references and restoration documentation remain the best guide for the final appearance decision.

Tire construction changes more than ride behavior on a restored 1958 Simca Vedette; it also changes the visual impression of the car. A 165-15 bias-ply keeps the vintage size format and tends to align more closely with a traditional restoration theme, while a 165R15 radial introduces a more modern construction in a classic-looking size.

Appearance also shifts with sidewall treatment, since the available 165R15 products include blackwall, narrow whitewall, and wide whitewall versions. That means a restored Vedette can be taken in several authentic-feeling visual directions without claiming that one sidewall or series is automatically factory-correct. Matching the tire's construction and sidewall to the car's trim, wheel covers, and restoration intent usually produces the most convincing result.

Yes. Modifications can change tire fitment on a 1958 Simca Vedette even when the nominal tire size remains 165-15 or 165R15. Aftermarket wheels, wheel-width changes, suspension work, altered ride height, or body repairs can all affect how much space the tire has at the fender, steering components, and inner wheelhouse.

That is especially important on an older car because decades of repairs can change fitment without leaving obvious clues. Checking the actual wheel dimensions and looking at clearance with the steering turned and the suspension loaded is far more reliable than assuming the car still matches original geometry. The same caution applies when considering equivalent radial sizes derived from the original bias-ply fitment.

Before putting a 1958 Simca Vedette back on the road with new tires, inspect the wheels for damage or excessive rust, verify that the rims match the tire's required diameter and width, and confirm proper inflation. It is also wise to check valve stems, lug hardware, and general tire clearance at both the front and rear.

A collector car deserves a broader walkaround before road use, especially if it has been parked for long periods. Look for uneven ride height, loose suspension parts, old alignment problems, and any signs that the previous tires rubbed under steering or compression. Taking a short, careful test drive and rechecking pressure afterward helps catch setup issues before a longer outing.

Tires on a collector 1958 Simca Vedette should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and irregular wear, and protected from long idle periods on underinflated tires. Even a low-mileage car needs routine checks because age and storage conditions can affect tire condition as much as road use does.

Storage habits matter on a vehicle like this. Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone-producing equipment helps preserve the rubber over time. It also helps to move the car occasionally or place it on an appropriate support strategy during long storage. Any tire showing persistent air loss or visible deterioration deserves attention before the Vedette returns to regular driving.
