The 1953 Panhard Dyna came from a period when French engineering often favored light weight, efficiency, and unconventional design over sheer size. That makes tire choice especially important on a car like this, where the character of the vehicle is closely tied to its original rolling proportions. For the 1953 Panhard Dyna, the applicable tire sizes are 135-400 and 145-400, both in radial construction. That gives owners a choice between two classic millimetric radial sizes rather than a bias-ply-versus-radial decision. The key is confirming which size suits the car’s current setup and choosing a tire that matches the look, stance, and intended road use of a restoration-minded Dyna.
Which Tire Size Is Right for The 1953 Panhard Dyna
The 1953 Panhard Dyna uses two primary tire sizes, and both are radial millimetric fitments rather than modern inch-based sizes. Because the covered Dyna sub-model can use either 135-400 or 145-400, the first step is confirming the car’s actual wheel and tire setup before choosing between them. Once that is settled, the decision becomes selecting the size that best matches the car’s present fitment and intended appearance.
135-400 is a classic millimetric radial size, with 135 referring to nominal section width in millimeters and 400 indicating the wheel diameter in millimeters. Its radial construction suits the 1953 Panhard Dyna’s documented fitment without introducing a construction change from the primary specification. For owners used to modern inch-based sizing, this format stands apart from later P-metric and alphanumeric systems and should be read on its own terms. It is a useful choice when the car is already set up for this narrower millimetric size and the goal is to preserve the vehicle’s proper proportions and clearance relationship.
145-400 is also a classic millimetric radial size, using a 145-millimeter nominal section width with a 400-millimeter wheel diameter. On a 1953 Panhard Dyna, it represents the second primary radial fitment and should be matched to the car’s actual wheel and existing setup rather than assumed from appearance alone. Buyers familiar with modern radial sizing should note that this is an older metric format, not a P-metric or Euro-metric size written with a slash and aspect ratio. It deserves a careful check when replacing tires on a restored or long-stored Dyna where wheel changes may have occurred over time.
Fitment for the covered 1953 Panhard Dyna sub-model is straightforward in construction but still requires attention to size. The 120 &130 can use either of the two millimetric radial sizes, so the important step is confirming which size is already mounted and which wheel setup the car carries.

Frequently Asked Questions
These FAQs focus on the millimetric radial tire sizes used on the 1953 Panhard Dyna, how to confirm the right fitment for the 120 &130 sub-model, and what to inspect before putting a collector-era car back on the road.
Tire Size & Fitment
What tire size fits a 1953 Panhard Dyna?
The 1953 Panhard Dyna uses two primary tire sizes: 135-400 and 145-400. Both are radial tires in a classic millimetric format, which differs from later inch-based and modern slash-format radial sizing. The covered Dyna 120 &130 sub-model can use either of these sizes.
That makes confirmation important before replacement. Check the size on the tire currently mounted, then verify that it matches the wheels on the car. On an older vehicle, wheels may have been changed during restoration or long-term service, so the safest approach is to confirm the actual mounted setup rather than choosing only by model name.
What size rim does a 1953 Panhard Dyna use?
The applicable tire sizes for the 1953 Panhard Dyna are 135-400 and 145-400, which both use a 400-millimeter wheel diameter. This is a millimetric rim size rather than the more familiar inch-based diameters seen on many later vehicles. That distinction matters because millimetric and inch sizes are not automatically interchangeable.
A buyer replacing tires on a Dyna should confirm that the car still has its 400-millimeter wheels before making a selection. On collector cars, wheel substitutions are not unusual, and a visual estimate is not enough. Reading the existing tire size and checking the wheel setup directly helps avoid ordering a correct tire size for the wrong wheel diameter.
Does the 1953 Panhard Dyna 120 &130 use the same tire size?
The 1953 Panhard Dyna 120 &130 is associated with the same two primary tire sizes used on this model range: 135-400 and 145-400. Both are radial millimetric fitments. So the sub-model does not point to one unique size by itself; either of the two sizes may be present on the car.
That means the deciding factor is the vehicle’s actual wheel and tire setup, not simply the sub-model name. A Dyna that has been restored, stored for years, or changed over time may not still wear the size it originally carried. Confirm the size molded into the existing tire and inspect wheel condition before choosing a replacement.
Choosing the Right Tire
What should I consider when choosing a 135-400 tire for a 1953 Panhard Dyna?
A 135-400 tire should be chosen only after confirming that this is the size currently used on the 1953 Panhard Dyna in question. It is a classic millimetric radial size, so the key considerations are correct wheel diameter, proper fit on the existing wheel, and maintaining the car’s established tire proportions.
For a collector car like the Dyna, appearance and setup matter almost as much as raw fitment. A narrower millimetric size can affect the vehicle’s visual stance and clearance relationship, so compare the current tires, inspect the wheels, and make sure the replacement supports the car’s restoration goals and normal driving use.
What should I consider when choosing a 145-400 tire for a 1953 Panhard Dyna?
Choosing a 145-400 tire for a 1953 Panhard Dyna starts with verifying that the car is already set up for that size. This is a millimetric radial fitment, not a modern inch-based tire, so the buyer should focus on matching the correct wheel diameter and preserving the car’s current fitment relationship.
On an older European car, even a small change in vintage tire sizing can alter the overall presentation of the vehicle. Before selecting 145-400, inspect the current tires, confirm the wheels, and make sure there is no confusion with another metric or inch-based size. That helps keep replacement choices grounded in the car’s actual configuration.
How do I choose between the available 135-400 and 145-400 tires for a 1953 Panhard Dyna?
The right choice between 135-400 and 145-400 depends on which size the 1953 Panhard Dyna is already equipped to use. Both are primary radial millimetric fitments for this model, so the decision is not about choosing between an old and modern construction style. It is about matching the vehicle’s existing wheel and tire setup.
Start by reading the size on the tires currently mounted and confirming the wheel diameter directly. A Dyna that has seen decades of ownership or restoration work may not still wear the same size it once did. Once the present setup is verified, choose the replacement that keeps the car’s proportions, clearance, and overall presentation consistent.
Restoration & Appearance
Which tire should I choose for a period-style 1953 Panhard Dyna?
For a period-style 1953 Panhard Dyna, the starting point is staying with one of the car’s primary millimetric radial sizes: 135-400 or 145-400. Both align with the Dyna’s documented radial fitment approach and preserve the vintage sizing format that suits an early-1950s French car better than a generic modern substitute.
The best appearance choice depends on the car’s current wheel setup and the look the restoration is trying to maintain. A careful comparison of the existing tire size, wheel condition, and overall stance will usually point the way. When exact originality is important, marque-specific historical references remain the right final check.
Does correct tire fitment matter for a 1953 Panhard Dyna restoration?
Yes, correct tire fitment matters on a 1953 Panhard Dyna because the car’s proportions, ride height impression, and overall presentation are closely tied to its compact millimetric tire sizing. Using one of the proper primary radial sizes, 135-400 or 145-400, helps keep the restoration grounded in the vehicle’s authentic fitment style.
Fitment also affects practical details beyond appearance. A different wheel setup or an incorrectly chosen size can create avoidable issues with clearance and visual balance. During restoration, confirm what is actually on the car, inspect the wheels carefully, and make tire selection part of the broader effort to preserve the Dyna’s character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1953 Panhard Dyna?
Yes, modifications can affect tire fitment on a 1953 Panhard Dyna. If the car has replacement wheels, altered suspension height, brake changes, or bodywork revisions, those changes may influence which of the two primary sizes, 135-400 or 145-400, works properly on the vehicle’s current setup.
A modified collector car should never be evaluated by model name alone. Check the actual wheel diameter, inspect available clearance at steering and suspension points, and compare the tire size already mounted. On a lightly used vintage car, those checks are especially important because past changes may not be obvious at first glance.
What should I inspect before driving a 1953 Panhard Dyna on new tires?
Before driving a 1953 Panhard Dyna on new tires, inspect the wheels for condition, verify that the mounted tire size matches the wheel setup, and check inflation carefully. It also makes sense to look over the suspension and steering for wear, since an older car can have issues that show up more clearly once fresh tires are installed.
Road use should begin with a slow, careful shakedown rather than a long first trip. Watch for rubbing, unusual steering feel, vibration, or air loss after installation. On a collector vehicle that may have spent long periods parked, even properly sized new tires perform best when the rest of the chassis is equally ready for the road.
How should 135-400 or 145-400 tires on a collector 1953 Panhard Dyna be maintained?
Collector-car tires in 135-400 or 145-400 should be maintained with regular pressure checks, visual inspections, and attention to age-related condition even when tread wear is low. On a 1953 Panhard Dyna, low annual mileage does not eliminate the need to watch for cracking, bulges, cuts, flat spotting, or gradual air loss.
Storage conditions matter as much as mileage on a lightly used vintage car. Keep the Dyna away from prolonged heat, direct sunlight, and moisture when possible, and inspect the tires before every meaningful drive. A brief walk-around before road use can catch condition issues early and help preserve both safety and ride quality.
