1961 Simca Arlane Tires

The 1961 Simca Arlane uses two primary tire sizes: 185R15 in radial construction and 6.50-15 in bias-ply construction. Both sizes are associated with the car and both fit a 15-inch wheel, so the fitment question is less about diameter and more about which tire construction best matches the way the car is being restored or driven.

A buyer choosing between them should confirm the actual wheel setup on the car, then decide whether a traditional bias-ply look or a radial format is the better match. Cars that have had wheel changes over the years should have rim width and clearance checked before settling on either size.

The 1961 Simca Arlane uses a 15-inch rim with either of its primary tire sizes. That applies to both the 185R15 radial and the 6.50-15 bias-ply fitments, so the wheel diameter remains consistent even though the tire sizing system and construction type change between the two choices.

Wheel diameter is only the first checkpoint. Rim width still matters, especially when comparing radial products, because the available 185R15 tires are built around specific wheel-width ranges. If the car has replacement wheels, verify the stamped wheel size and inspect inner and outer clearance before mounting a new set.

On a 1961 Simca Arlane, 6.50-15 is a numeric bias-ply tire size. The 6.50 refers to the nominal section width in inches, and the 15 identifies the wheel diameter. Unlike modern metric sizes, this older format does not spell out the same kind of aspect-ratio information buyers may be used to seeing on later radial tires.

That matters because a 6.50-15 is not just another way of writing a modern radial size. It points to a different construction style and a different approach to period appearance. Anyone moving away from bias-ply should compare wheel dimensions and overall fitment carefully instead of assuming modern radial sizing behaves the same way.

For the 1961 Simca Arlane, 6.50-15 is a bias-ply tire size. It uses the older numeric sizing convention commonly associated with vintage tire construction, while the Arlane's radial option appears separately as 185R15. The two sizes share the same 15-inch rim diameter, but they represent different tire-building methods and a different ownership decision.

Choosing 6.50-15 usually means prioritizing a more traditional presentation and period-style driving character. Moving to a radial setup changes more than the lettering on the sidewall, so the wheel width, suspension condition, and available clearance should be reviewed before changing construction on a car that may have seen decades of service or modifications.

The 1961 Simca Arlane can be equipped with either 6.50-15 bias-ply tires or 185R15 radial tires, so the right choice depends on your priorities. Bias-ply suits an owner focused on a more traditional period-style look, while 185R15 radial options open up more variety in brand, sidewall styling, and radial construction within the same 15-inch wheel diameter.

The best decision starts with how the car will be used. A restoration-oriented car may lean toward bias-ply for appearance, while a road-driven Arlane may prompt closer consideration of radial products. Before switching, confirm the wheel width on the car and inspect fender and steering clearance rather than assuming any 15-inch tire choice behaves the same.

A 1961 Simca Arlane owner considering a move from 6.50-15 bias-ply to 185R15 radial should first confirm that the car is actually using 15-inch wheels in suitable width for the radial tire being considered. The available 185R15 products include different rim-width ranges, so wheel compatibility is part of the conversion decision, not just the tire size itself.

It also helps to inspect steering clearance, suspension condition, and the space around the tire at full lock and normal ride height. Cars that have replacement wheels, worn bushings, or altered ride height deserve extra attention. A conversion can be worthwhile, but it should be treated as a fitment review rather than a simple change in sidewall markings.

Choosing a 185R15 tire for a 1961 Simca Arlane starts with confirming that a radial setup is the right direction for the car. From there, compare the available tire series, sidewall styles, and rim-width compatibility. In this size, options include Michelin XVS, Coker Classic Radial, Universal Sport, and Avon Turbosteel CR3B, so the differences are meaningful rather than cosmetic alone.

Appearance and wheel fit should guide the final decision. A blackwall, redline, or narrow whitewall creates a noticeably different look on a small early-1960s sedan, and the wheel itself needs to match the tire's acceptable width range. Looking at load figures and product weight can also help narrow the field when more than one radial option fits the car's purpose.

For the 1961 Simca Arlane, the available 185R15 radial products include blackwall, redline, and narrow whitewall sidewall styles. Those choices can change the visual tone of the car considerably, from a restrained European blackwall look to a more styled period presentation with a redline or a subtle whitewall treatment.

Sidewall style should be chosen as part of the overall restoration or road-use plan rather than as a stand-alone detail. A buyer trying to preserve a clean stock-looking appearance may lean one direction, while someone building a more personalized vintage presentation may choose another. The important point is to keep the sidewall decision secondary to correct size, construction, and wheel compatibility.

The 1961 Simca Arlane has 185R15 radial tire options from Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those products appear across series such as Coker Classic Radial, Michelin XVS, Universal Sport, and Turbosteel CR3B, giving buyers several ways to compare brand character, sidewall appearance, and product specifications within the same basic fitment.

Brand choice should be weighed alongside the rest of the tire's details instead of treated as the only deciding factor. One product may offer a redline sidewall, another a narrow whitewall, and another a blackwall with a different rim-width range or load figure. Matching the tire to the car's look and wheel setup usually matters more than the brand name alone.

For a period-style 1961 Simca Arlane, the first decision is whether the car should retain a traditional bias-ply presentation or use a radial tire that still looks appropriate for the era. The 6.50-15 bias-ply size is the natural starting point for a more vintage-correct visual impression, while 185R15 radial options can still support a tasteful early-1960s appearance.

That choice depends on the level of restoration accuracy being pursued. Owners aiming for a historically faithful presentation should compare tire size, construction, and sidewall treatment with marque references or period photos. Drivers focused on road use may still prefer a radial, but the sidewall style should be selected carefully so the car does not lose its era-appropriate character.

Tire construction affects a restored 1961 Simca Arlane both visually and proportionally. A 6.50-15 bias-ply presents the car in a more traditional vintage manner, while a 185R15 radial introduces a later-style construction even though it remains a 15-inch fitment. On a compact French sedan, that difference can influence how authentic and settled the car looks at a glance.

Sidewall styling adds another layer to the appearance decision. Blackwall tends to keep the presentation restrained, while redline or narrow whitewall options create a more styled look. Anyone restoring the car to a very specific historical standard should verify period references before choosing a sidewall treatment, since available tire styles are not automatically exact to original delivery.

Yes, modifications can affect tire fitment on a 1961 Simca Arlane even when the tire size itself is correct. Replacement wheels, changes in wheel width, suspension work, altered ride height, or body repairs can all change how a 185R15 radial or 6.50-15 bias-ply sits in the wheel opening and how much clearance remains during steering and suspension movement.

Any Arlane with non-original wheels or a changed stance should be checked carefully before mounting new tires. Look at inner clearance, outer fender space, and steering travel rather than relying on the size code alone. Small vintage cars can be especially sensitive to wheel and suspension changes that seem minor but still affect fitment.

Before driving a 1961 Simca Arlane on new tires, inspect the wheels for correct diameter and width, then confirm proper mounting and inflation. It is also wise to look over the suspension, steering components, and brake hardware, since a freshly mounted tire can reveal play or rubbing that was hidden by an old, worn, or poorly sized tire.

A short initial drive should be followed by another inspection for contact marks, air loss, and any sign that the tire is not seating or clearing as expected. Vintage cars that sit for long periods deserve extra attention to wheel condition and fastener torque. Catching those issues early helps protect both the new tires and the car.

Tires on a collector 1961 Simca Arlane should be maintained with regular pressure checks, visual inspections, and careful storage habits. Whether the car is running 185R15 radial tires or 6.50-15 bias-ply tires, low annual mileage does not prevent aging. Cracking, bulges, cuts, uneven wear, and persistent air loss deserve attention even if the tread still looks serviceable.

Storage conditions matter almost as much as road use on an older collector car. Keeping the Arlane away from prolonged sunlight, moisture, and ozone sources can help preserve the tires between drives. It also helps to inspect the tires before every outing and after long storage periods, since age-related issues can appear before the car accumulates many miles.
