Compact French cars of the mid-1960s were built around light weight, efficient packaging, and nimble road manners, and the 1966 Renault Renault reflects that distinctly European approach. For owners keeping one on the road today, tire choice is less about sorting through multiple factory fitments and more about choosing the right version of its original-size radial. This vehicle uses a 145R15 radial on a 15-inch rim, giving it a straightforward fitment path. Within that size, there are still meaningful choices in brand, tire series, and sidewall appearance, including blackwall and wide whitewall options. That makes it important to balance road use, wheel compatibility, and the look you want from the finished car.
Which Tire Size Is Right for The 1966 Renault Renault
The 1966 Renault Renault uses one primary tire size: 145R15, a radial tire for a 15-inch rim. Because fitment is consistent here, the real decision is not choosing between multiple primary sizes, but selecting the right tire within 145R15 based on brand, sidewall style, rim-width compatibility, and the appearance you want for the car.
A 145R15 is a Euro-metric radial size, with 145 indicating nominal section width in millimeters, R identifying radial construction, and 15 referring to rim diameter in inches. This format is commonly associated with an 80-series profile, which suits the light, compact character of a 1966 Renault Renault. In this size, available choices include Firestone, Michelin, and BFGoodrich, with blackwall and wide whitewall presentations across tire series such as F560 Radial, Michelin XZX, and Silvertown Radial. Choosing among them comes down to matching the tire to your wheel width, intended driving use, and restoration style.
Fitment is straightforward across the covered sub-models because the same primary tire size is used throughout. Checking the exact sub-model still helps confirm that the car remains on the correct wheel and tire setup before choosing among available radial options.

Tire Size & Fitment
What tire size fits a 1966 Renault Renault?
The 1966 Renault Renault uses a 145R15 radial tire. That is the primary fitment for this vehicle, and it places the tire on a 15-inch rim using a classic Euro-metric sizing format rather than a modern P-metric designation.
That makes size selection fairly straightforward, but the correct tire still depends on the wheel that is actually on the car. A vintage Renault may have replacement wheels or long-ago modifications, so it is smart to confirm the rim diameter and wheel width before choosing among the available 145R15 radial options.
What size rim does a 1966 Renault Renault use?
The primary tire fitment for a 1966 Renault Renault is built around a 15-inch rim. That rim diameter matches the 145R15 size code, where the final number identifies the wheel diameter the tire is designed to mount on.
Rim diameter is only part of the fitment picture on an older vehicle. It also helps to verify wheel width, especially if the car has been stored for years or fitted with non-original wheels, because the available 145R15 products do not all share the exact same recommended rim-width range.
Does the 1966 Renault Renault 8 use the same tire size?
Yes. The 1966 Renault Renault 8 uses the same 145R15 radial tire size. That keeps fitment simple and means the main differences are found in the available tire brands, tire series, and sidewall appearance rather than in separate primary sizes.
Even with the same nominal size, it is still worth checking the actual wheel setup on the car before ordering tires. A Renault 8 that has seen wheel changes, brake work, or suspension alterations may need closer inspection for wheel width and clearance before settling on a specific 145R15 radial.
Choosing the Right Tire
What should I consider when choosing a 145R15 tire for a 1966 Renault Renault?
Start with the basics: the 1966 Renault Renault uses a 145R15 radial on a 15-inch rim. From there, the meaningful differences are brand, tire series, sidewall style, and wheel-width compatibility, since some 145R15 products are intended for slightly different rim-width ranges.
The best choice depends on how the car will be used and how you want it to look. A blackwall tire keeps a simple European presentation, while a wide whitewall changes the visual character more noticeably, so matching the tire to both the wheel and the finished appearance matters.
What sidewall styles are available for 1966 Renault Renault tires?
The available 145R15 tires for a 1966 Renault Renault include both blackwall and wide whitewall sidewall styles. That gives owners a choice between a more understated, traditional radial appearance and a more decorative whitewall presentation in the same basic size.
Sidewall style affects appearance more than fitment, but it can shape the whole character of the car once mounted. Choosing between blackwall and wide whitewall usually comes down to restoration direction, personal preference, and whether the tire’s overall look matches the wheel and trim presentation already on the vehicle.
What brands offer tires for the 1966 Renault Renault?
145R15 tires for the 1966 Renault Renault are available from Firestone, Michelin, and BFGoodrich. The tire series represented in this fitment include Firestone F560 Radial, Michelin XZX, and BFGoodrich Silvertown Radial, all within a radial construction layout.
Brand choice should be weighed alongside sidewall style and wheel compatibility rather than treated as the only decision. Comparing the tire series, checking the wheel width on the car, and deciding whether you want a blackwall or wide whitewall look will usually narrow the selection more effectively.
Restoration & Appearance
Which tire should I choose for a period-style 1966 Renault Renault?
A period-style approach starts with the correct primary fitment, which is 145R15 in radial construction. Within that size, the most restoration-minded choices usually come down to whether you want a simple blackwall presentation or a more stylized wide whitewall look on the finished car.
For many vintage European cars, keeping the proper size and overall visual proportion matters more than chasing novelty. If exact originality is important, compare your choice against marque references and surviving examples, then make sure the selected tire also matches the wheel width and intended road use.
Does correct tire fitment matter for a 1966 Renault Renault restoration?
Yes, correct tire fitment matters because a small vintage car like the 1966 Renault Renault depends heavily on proper tire proportions for its stance and overall presentation. Using the proper 145R15 size helps preserve the visual balance that suits the car’s compact body and 15-inch wheel setup.
Appearance is only part of the equation. Staying with the correct size also makes it easier to avoid clearance or wheel-compatibility issues that can come from casual substitutions, especially on restored cars that may have mixed components or replacement wheels accumulated over many years.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1966 Renault Renault?
Yes. Even though the primary size for a 1966 Renault Renault is 145R15, modifications can change what actually works on the car. Aftermarket wheels, altered ride height, brake changes, or body repairs can all influence wheel width, clearance, and the way the tire sits in the wheel opening.
That is why an older vehicle should be measured, not assumed. Checking the actual rim diameter and width, looking at steering and fender clearance, and inspecting the suspension condition will help confirm that a chosen 145R15 tire suits the car as it is currently configured.
What should I inspect before driving a 1966 Renault Renault on new tires?
Before road use, inspect the wheels, valve stems, lug hardware, and overall tire clearance on the 1966 Renault Renault. It also makes sense to look over the suspension and steering components, since worn bushings, loose parts, or alignment issues can affect how a fresh set of 145R15 radials behaves.
Collector cars often spend long periods parked, so the inspection should extend beyond the tires themselves. Verify air pressure, watch for any rubbing during low-speed steering, and make sure the car tracks cleanly before taking a longer drive, especially if the vehicle has just returned to service.
How should 145R15 tires on a collector 1966 Renault Renault be maintained?
145R15 tires on a collector 1966 Renault Renault should be maintained with regular pressure checks, visual inspections, and sensible storage practices. Look for cuts, cracking, bulges, uneven wear, or persistent air loss, because low-use vintage cars can age tires out long before they wear them out.
Storage conditions matter almost as much as mileage on an older Renault. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the rubber, and occasional inspections between drives can catch early issues before they turn into road-use problems.
