Chrysler CM6 Tires

Chrysler CM6 uses a single listed tire size: 5.25-19 for the 1931 model year. That means the tire has a nominal 5.25-inch section width and mounts on a 19-inch wheel, which is the key wheel diameter to confirm on the car before fitting replacement tires.

Because only one size is listed, the main fitment question is usually not the year but whether the wheels on a particular Chrysler CM6 are still original to the car. Many pre-war cars have been restored, stored, or altered over the decades, so measuring the wheel and comparing it with period references is the smart first step.

On Chrysler CM6, the size 5.25-19 is a period numeric tire designation. The 5.25 figure refers to the nominal section width in inches, while 19 is the rim diameter in inches. It is not a modern metric size, so it should be interpreted as a pre-war bias-ply measurement rather than compared directly to a current passenger-car radial size.

Understanding that code helps avoid one of the most common vintage tire mistakes, which is choosing a tire by appearance alone instead of by the actual wheel diameter and period sizing system. A Chrysler CM6 owner should match both the 19-inch wheel and the proper vintage profile so the car sits and drives as intended for its era.

Chrysler CM6 uses a 19-inch rim with the listed 5.25-19 tire size. The wheel diameter is built into the size code in this case, so the critical fitment dimension is a 19-inch wheel rather than a smaller or larger rim from another Chrysler application.

That matters because pre-war wheels are often visually similar across neighboring sizes, and a car that has gone through restoration may not still wear the wheels it left with decades ago. A quick measurement of the actual rim and a check against original Chrysler literature will prevent ordering a tire profile that looks close but mounts incorrectly.

Chrysler CM6 should be treated as a tube-type application because the listed 5.25-19 size is a pre-war bias-ply style fitment. Tube-type construction is normal for this era, and the tire and wheel package should be assembled accordingly rather than approached like a later tubeless radial installation.

That practical detail matters just as much as the size itself, since an otherwise correct tire can still be fitted improperly if the tube, flap, or wheel condition is overlooked. Before mounting tires on a Chrysler CM6, inspect the wheel thoroughly for rust, burrs, spoke-end issues if applicable, and any restoration work that could affect tube service.

For a 1931 Chrysler CM6, the listed tire size is 5.25-19. Confirmation starts with the wheel itself: verify that the car still carries 19-inch rims and compare the existing equipment against factory literature, restoration records, or established Chrysler references for the specific car.

That extra verification is worthwhile because many pre-war cars have lived through wheel swaps, mixed parts, and older restorations. If your Chrysler CM6 has an uncertain history, inspect all four wheels and the spare, then make sure the tire size, wheel diameter, and overall stance agree before choosing replacement tires for a full set.

Made-to-order means a Chrysler CM6 tire is produced as a specialty vintage item rather than treated like a routine modern replacement. That designation is common in collector tire categories where production runs are smaller and focused on preserving correct period sizes and construction styles for older automobiles.

For the buyer, the important point is that made-to-order status speaks to how specialized the tire is, not to whether it is correct for the car. On a Chrysler CM6, fitment and construction remain the priority, so verify the 5.25-19 size, the 19-inch rim, and the tube-type pre-war setup before deciding which version best suits your restoration goals.

Chrysler CM6 tires can appear in different vintage-style series depending on the product range offered for the 5.25-19 size. Those series distinctions generally separate construction approach, tread character, and period presentation rather than changing the basic fitment, which remains centered on the same wheel diameter and nominal section width.

For a Chrysler CM6 owner, the choice between series is usually about restoration intent. A more period-focused build may favor the series that most closely matches the car's original era and visual character, while a touring-minded owner may prioritize another vintage-style option in the same size. Keep the size and wheel match fixed first, then compare series details.

A Chrysler CM6 should be stored in a cool, dry, dark place with the tires kept away from direct sunlight, ozone sources, and petroleum contamination. Pre-war tire constructions are especially sensitive to long periods of disuse, so stable indoor conditions help preserve the casing, sidewalls, and tube-type assembly.

Good storage practice also means managing the car's weight on the tires. If a Chrysler CM6 will sit for extended periods, move it occasionally or use appropriate support methods to reduce flat spotting and sidewall stress. Keep inflation checked during storage as well, since an underinflated collector tire deteriorates faster under static load.

Tires on a Chrysler CM6 should be inspected before every drive and more thoroughly at regular intervals during the driving season. On a pre-war car, that inspection should include sidewall cracking, tread separation, bead condition, tube-related issues, valve stem condition, and any signs that the wheel itself could damage the tire assembly.

Frequent inspection matters because collector cars often accumulate little mileage while still aging continuously. A Chrysler CM6 may look fine in the garage and still develop age-related problems that only appear under load. If anything seems questionable, have the tires and wheels checked by a shop experienced with vintage tube-type assemblies rather than a general modern tire counter.

Tires on a Chrysler CM6 should be replaced when age, cracking, deformation, hardening, or structural concerns appear, even if the tread still looks deep. Low-mileage collector tires often age out before they wear out, and that is especially true on pre-war applications where the construction and service conditions are very different from modern daily-driver tires.

A Chrysler CM6 owner should think in terms of condition and age rather than tread alone. Any tire with visible deterioration, uncertain service history, or long inactive storage should be evaluated carefully before road use. Replacement becomes the prudent choice once the casing no longer inspires confidence, because preservation of the car and its occupants matters more than maximizing tire life.

Chrysler CM6 is associated here with the 5.25-19 size for the 1931 model year, which identifies the period tire size family used on the car. Original equipment branding is a separate question, but the key authenticity point is that the car belongs with a pre-war tire in the proper 19-inch fitment and vintage construction style.

For a restoration, that means starting with the correct size and overall period appearance rather than chasing a name on the sidewall first. If the goal is concours-level accuracy for a Chrysler CM6, compare the car against original Chrysler literature, marque-club references, and surviving examples to refine details beyond the basic 5.25-19 fitment.

Correct tire fitment can absolutely affect how a Chrysler CM6 is judged and how authentic it appears to knowledgeable enthusiasts. Size, profile, construction style, and sidewall presentation all contribute to whether the car looks properly finished for the 1931 period, even before anyone studies smaller restoration details.

That influence is not just cosmetic. The wrong overall tire dimensions can change stance, wheelwell fill, and the visual balance that makes a pre-war Chrysler look right. If your Chrysler CM6 is being restored for judged events or high-level presentation, use marque-club guidance and period photos to confirm the tire's visual character along with the core 5.25-19 fitment.

The correct sidewall style for a Chrysler CM6 restoration depends on the specific tire version chosen within the proper 5.25-19 vintage fitment. On pre-war cars, sidewall appearance is part of the overall historical presentation, and the right choice should match the car's restoration objective rather than follow later collector-car trends.

A preservation-minded Chrysler CM6 should use a sidewall treatment that suits early-1930s practice and the character of the car as restored. When authenticity matters, compare available sidewall styles against period photos, factory sales material, and established Chrysler references so the tire complements the body, wheels, and trim instead of standing out as a modern interpretation.

A properly fitted, correctly maintained vintage tire can be suitable for careful public-road use on a Chrysler CM6, but it should be approached as collector-car equipment rather than modern high-speed transportation. The car's pre-war chassis, braking, steering, and tire construction all shape what safe operation looks like in present-day traffic.

That means a Chrysler CM6 should be driven conservatively and only after the complete vehicle has been checked mechanically. Tire condition is only one part of the picture. Wheel integrity, tube condition, alignment, brake performance, and steering play all need to be right before regular road use is considered responsible.

Before driving a Chrysler CM6, inspect tire inflation, sidewalls, tread condition, valve stems, wheel hardware, and the general integrity of the tire-and-wheel assembly. On a pre-war car, it is equally important to check brakes, steering response, wheel bearings, and whether the spare matches the mounted tires closely enough to serve in an emergency.

A short walk-around before every outing can prevent the most common collector-car problems from becoming roadside failures. Chrysler CM6 owners should also pay attention to how the car feels at low speed in the first few minutes of a drive. Any pull, wobble, vibration, or unusual sound is reason to stop and inspect before continuing.

A Chrysler CM6 on correct vintage-style tires should be driven at moderate, sensible speeds that respect both the pre-war tire construction and the capabilities of the car itself. Even with fresh tires, the experience is fundamentally different from driving a modern vehicle, and sustained high-speed use is not the point of a 1931 Chrysler.

The practical rule is to treat a Chrysler CM6 as a touring or show car, not as a machine for fast freeway traffic. Build speed gradually, keep generous space around the car, and let road, weather, and mechanical condition dictate how quickly you travel. The safest pace is the one that keeps the car settled and fully under control.
