The 1957 Renault CV belongs to the postwar European small-car era, when compact dimensions, light weight, and practical road manners mattered more than excess size or power. Owners today often approach this Renault as a charming restoration project or a simple, enjoyable vintage driver. Tire choice on the 1957 Renault CV centers on two 15-inch fitments: a 5.20-15 bias-ply for a more traditional presentation and a 145R15 radial for a later-style metric alternative. Within that fitment range, the main differences come from construction, sidewall appearance, and brand selection. The right choice depends on whether the goal is period-style character, easier road use, or a balance of both.
Which Tire Size Is Right for The 1957 Renault CV
The 1957 Renault CV uses two primary tire sizes, and both fit the same 15-inch rim diameter. The choice is less about sub-model differences and more about construction, since the Base model can use either a 5.20-15 bias-ply or a 145R15 radial. That makes the real decision one of driving character, appearance, and confirming that the wheel width and overall setup suit the tire you plan to run.
145R15 is a Euro-metric radial size in which 145 refers to nominal section width in millimeters, R designates radial construction, and 15 identifies the wheel diameter in inches. On a 1957 Renault CV, this size offers a radial-format option while staying with the correct 15-inch rim diameter. Available choices include Firestone, Michelin, and BFGoodrich, with blackwall and wide whitewall sidewall styles across series such as F560 Radial, Michelin XZX, and Silvertown Radial. It is a useful size to evaluate if road use, brand preference, or sidewall presentation matters as much as vintage fitment character.
5.20-15 is a numeric bias-ply size, with 5.20 representing the nominal section width in inches and 15 indicating the wheel diameter. That format is closely associated with mid-century tire sizing and gives the 1957 Renault CV a more traditional construction style than a modern radial-format alternative. Bias-ply selection is often driven by period-style appearance and the original feel owners want from a small vintage European car. It is the size to consider when preserving a more authentic visual stance matters more than moving to a radial construction.
Fitment is straightforward across the covered 1957 Renault CV sub-models, since the Base model uses the same two 15-inch tire sizes. Checking the exact sub-model still matters so the tire choice stays focused on the correct construction and overall presentation for the car.

1957 Renault CV Base
The 1957 Renault CV Base can be fitted with either the 145R15 radial or the 5.20-15 bias-ply on a 15-inch rim. That gives the owner a clear choice between a traditional bias-ply presentation and a radial-format tire, along with available sidewall and brand differences within the radial options.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1957 Renault CV Tires for Sale
Available 145R15 choices for the 1957 Renault CV include Firestone, Michelin, and BFGoodrich radials in distinct series and sidewall treatments. The product grid is where to compare blackwall versus wide whitewall presentation, radial construction details, and rim-width compatibility across the available 15-inch options.
Common 1957 Renault CV tire questions usually come down to choosing between 5.20-15 bias-ply and 145R15 radial fitment, understanding the 15-inch rim requirement, and deciding how appearance, road use, and wheel setup affect the final choice.
Tire Size & Fitment
What tire size fits a 1957 Renault CV?
The 1957 Renault CV uses two primary tire sizes: 145R15 in radial construction and 5.20-15 in bias-ply construction. Both are 15-inch fitments, and the covered Base model can use either size depending on the type of tire setup you want on the car.
That means the first step is deciding whether to keep a more traditional bias-ply style or move to a radial-format tire in the correct wheel diameter. Before choosing, confirm the actual wheels on the car, especially if they may have been changed over the years, and make sure the rim width and overall clearance suit the tire you plan to use.
What size rim does a 1957 Renault CV use?
The 1957 Renault CV uses a 15-inch rim diameter with both of its primary tire sizes. The radial 145R15 and the bias-ply 5.20-15 are both built around that same 15-inch wheel size, so wheel diameter remains consistent across the fitment choices.
Rim diameter is only one part of the fitment picture, though it is the most important place to start. Wheel width can still affect which tire is appropriate, especially when comparing available radial products, so it is worth checking the wheel itself rather than assuming every 15-inch wheel on the car is the same.
Does the 1957 Renault CV Base use the same tire size?
Yes. The 1957 Renault CV Base uses the same two tire-size options associated with this model: 145R15 in radial construction and 5.20-15 in bias-ply construction. There is no separate sub-model tire-size split within the covered CV Base fitment.
That keeps the decision centered on construction and tire style rather than trim-level differences. A buyer can focus on whether the car is being set up for a more traditional period-style look with bias-ply tires or for radial-format road use, while still verifying the actual wheel and suspension setup on the individual vehicle.
Choosing the Right Tire
What should I consider when choosing a 145R15 or 5.20-15 tire for a 1957 Renault CV?
Start with the correct size and construction for the way the car will be used. A 5.20-15 bias-ply keeps the selection closer to a traditional mid-century tire format, while a 145R15 radial gives the Renault CV a metric radial option on the same 15-inch rim diameter.
After that, compare wheel width, sidewall style, and the look you want the car to have when parked and driving. Cars that have been modified, lowered, or fitted with replacement wheels deserve extra attention, since a vintage Renault with a changed setup may need more careful checking before settling on one construction or the other.
What sidewall styles are available for 1957 Renault CV tires?
The available 145R15 radial choices for the 1957 Renault CV include blackwall and wide whitewall sidewall styles. That gives owners a straightforward appearance choice within the correct 15-inch radial fitment, rather than limiting the car to a single visual treatment.
Sidewall style affects the overall presentation more than the basic fitment itself, so the better choice depends on how the Renault is being restored or displayed. A blackwall keeps the look simple and understated, while a wide whitewall creates a stronger vintage visual statement without changing the wheel diameter or basic tire size.
What brands offer tires for the 1957 Renault CV?
The 145R15 radial size for the 1957 Renault CV is available from Firestone, Michelin, and BFGoodrich. Those options also span different tire series, including Firestone F560 Radial, Michelin XZX, and BFGoodrich Silvertown Radial, which gives the buyer more than one approach within the same size.
Brand choice should still come after confirming the right size, construction, and wheel compatibility for the car. Once that foundation is settled, the decision becomes more about the character of the tire offering, the sidewall appearance you want on the Renault, and how closely the finished look matches your restoration or driving goals.
Restoration & Appearance
Which tire should I choose for a period-style 1957 Renault CV?
A 5.20-15 bias-ply is the natural starting point for a period-style 1957 Renault CV because it keeps the car in a vintage numeric bias-ply format. That construction suits owners who want the tire choice to reflect the character of a small mid-1950s European car rather than a later radial-style presentation.
Appearance goals should be balanced with how the Renault will actually be driven. If exact historical detail matters, it is wise to compare tire choices against marque-club guidance or other vehicle-specific references, while owners who prefer more frequent road use may still look closely at the 145R15 radial as an alternative path.
How does tire construction affect the appearance of a restored 1957 Renault CV?
Tire construction changes the visual character of a restored 1957 Renault CV as much as the size itself. A 5.20-15 bias-ply delivers a more traditional vintage tire format, while a 145R15 radial introduces a later-style metric look even though it still fits the same 15-inch wheel diameter.
That difference matters when the car is being restored for display, touring, or a balanced driver-quality result. Sidewall treatment also shapes the final impression, since the available 145R15 radial products include both blackwall and wide whitewall styles, allowing the car to lean either understated or more overtly restoration-oriented.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1957 Renault CV?
Yes. Even though the 1957 Renault CV uses 15-inch tire fitments, modifications can still change what works well on the car. Replacement wheels, altered wheel width, suspension changes, ride-height changes, or body repairs can all influence whether a 145R15 radial or 5.20-15 bias-ply remains a comfortable fit.
A modified car should be checked at the wheel and at full steering movement rather than judged by size code alone. Clearance around the fenders, steering components, and suspension matters, and an older Renault that has lived through decades of repairs may not match its original setup closely enough to rely on assumptions.
What should I inspect before driving a 1957 Renault CV on new tires?
Start by confirming the wheel diameter, wheel condition, and valve hardware, then inspect the suspension and steering for looseness that could affect how the 1957 Renault CV behaves on fresh tires. Tire pressure should be checked before road use, and each tire should be examined for proper seating and visible clearance around the body and chassis.
A short test drive is a smart final check, especially on a lightweight vintage car where small setup issues are easy to notice. Watch for rubbing in turns, uneven stance, vibration, or pulling, and recheck the tires afterward so any mounting or clearance issue is caught early rather than after a longer drive.
How should 145R15 or 5.20-15 tires on a collector 1957 Renault CV be maintained?
Collector-car tires on a 1957 Renault CV should be inspected regularly for pressure loss, sidewall cracking, cuts, bulges, and uneven tread wear, even if the car is driven only occasionally. Low annual mileage does not stop tires from aging, so condition matters just as much as remaining tread depth.
Storage also has a big effect on long-term tire life. Keeping the Renault away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and it is wise to check them again before each driving season so an older-looking set is not mistaken for a road-ready one.
