1927 Kissel Tire Fitment Guide

1927 Kissel vehicles use two tire sizes: 33X6.00 and 600-21. Both sizes apply to the full 1927 Kissel model range covered here, including the Kissel 55 and Kissel 75. The listed products for 600-21 mount on 21-inch rims, and that same 21-inch rim diameter also applies to 33X6.00 in this application.

The practical question is not which model needs a different size, because the 55 and 75 share the same pair of sizes. The important step is confirming which size format is already on your car, since an antique diameter-by-section marking and a numeric bias-ply marking are not simply interchangeable by name alone. Checking the actual wheel and existing tire before choosing will keep the car consistent and avoid ordering the wrong style of vintage fitment.

A 33X6.00 tire on a 1927 Kissel uses an antique diameter-by-section format. The first number, 33, refers to the tire's overall diameter in inches, while 6.00 refers to the nominal section width. It is a bias-ply type size commonly associated with earlier automotive tire conventions.

That older sizing style matters because it identifies the tire by outside diameter rather than by the more familiar later width-and-rim shorthand many modern buyers recognize. On a 1927 Kissel, 33X6.00 is shared by both the 55 and 75, so the issue is not model fitment but whether your car is currently set up for that antique size system. If you are restoring a prewar car and want to keep the visual language of the period intact, this size usually deserves close attention.

A 600-21 tire on a 1927 Kissel is a numeric bias-ply size. The 6.00 refers to the nominal section width, and the 21 refers to the wheel diameter in inches. For 1927 Kissel applications, this size is offered in bias-ply construction from Lester and BFGoodrich, with blackwall and wide whitewall versions available.

This format is more familiar to many vintage tire buyers because it clearly identifies the rim diameter in the size code itself. Since both 1927 Kissel models use 600-21, the decision comes down to whether your car is already fitted for that numeric size and what appearance you want from the sidewall. A blackwall keeps the look restrained, while a wide whitewall gives the car a more formal late-1920s presentation.

A 1927 Kissel can use either 33X6.00 or 600-21 depending on the setup of the car, and both are bias-ply rather than a bias-versus-radial decision. The main difference is the sizing system and the way each tire presents itself within a prewar restoration. Both the Kissel 55 and Kissel 75 share these sizes, so the choice is not tied to one specific model.

Owners focused on strict period character often start by matching the exact size format already associated with their wheels and restoration plan. Owners who want a recognized numeric replacement size with listed brand and sidewall options may lean toward 600-21, especially when choosing between blackwall and wide whitewall presentation. The smartest approach is to inspect the current tires and wheels first, then stay consistent with the car's established fitment direction rather than choosing by appearance alone.

1927 Kissel tires in 600-21 are available in both Blackwall and Wide Whitewall form. Lester offers a blackwall version, while BFGoodrich offers both blackwall and a 3.50-inch wide whitewall in this size. Both sidewall styles are tied to bias-ply construction, which is appropriate to the late-1920s character of the marque.

Sidewall style changes the car's visual impression more than many buyers expect. A blackwall generally gives a more restrained and workmanlike appearance, while a wide whitewall brings a dressier luxury-car look that many owners prefer on upscale prewar automobiles. If your 1927 Kissel is being judged or restored to a particular market presentation, check period photos, club references, or event standards before deciding which sidewall treatment best supports the car's intended finish.

Lester and BFGoodrich both offer tires for 1927 Kissel vehicles in the 600-21 size. Lester appears here in a blackwall classic bias-ply version, while BFGoodrich offers classic bias-ply choices in both blackwall and wide whitewall form. Both brands fit the collector-car world well and suit the era of the Kissel name.

Brand choice on a prewar car is often as much about restoration taste as about fitment. Some owners prefer the understated look of a basic blackwall tire, while others want the visual presence of a whitewall from a historically familiar American brand. Since both 1927 Kissel models share the same listed 600-21 brand options, compare the appearance, load information where given, and the overall look you want the car to carry at shows or on tours.

For 1927 Kissel tires in size 600-21, listed BFGoodrich products specify a rim width range of 3.00 to 3.75 inches on a 21-inch rim. The 33X6.00 size is also used on 21-inch wheels in this application, but a rim width range is not listed alongside it here. Both the Kissel 55 and Kissel 75 share these same size options.

That means 600-21 buyers have a clear benchmark for wheel compatibility on products where rim width is stated, while 33X6.00 owners should compare carefully against the actual wheel already on the car. Prewar wheels can vary after decades of repairs, substitutions, or earlier restorations. Measuring the wheel and matching it to the specific tire's approved range is more useful than assuming all 21-inch wheels are equivalent just because the nominal rim diameter matches.

1927 Kissel tire listings here do not show tube-type or tubeless markings in the size field for the available 600-21 products. Since these are late-1920s bias-ply applications on prewar-style wheels, tube use is a setup detail that should be confirmed against the specific wheel construction and the exact tire being chosen rather than assumed from size alone.

That matters because many collector cars use wheels and rims that have changed over time, and the wheel often determines whether a tube is appropriate just as much as the tire itself. Before mounting tires on a 1927 Kissel, inspect the wheel condition, valve stem arrangement, and the wheel's sealing surfaces. If the car has split-ring or other specialized prewar wheel hardware, a marque specialist or experienced vintage tire installer is the right person to consult.

Both listed 1927 Kissel sizes use 21-inch wheels, so they share the same rim diameter in that sense. That applies across both the Kissel 55 and Kissel 75. Rim diameter compatibility is the first requirement, and both sizes meet it.

The next step is not to assume that every original wheel suits every tire choice equally well. Wheel width, wheel condition, and the way the car has been restored over the years all affect whether a given tire is the right physical match. If your car already carries one of these two sizes, staying with that established format is often the most straightforward path unless you are deliberately correcting an earlier fitment decision during restoration.

A 1927 Kissel should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber. Bias-ply tires also benefit from proper inflation during storage and from occasional movement of the car to avoid long-term flat spotting. Clean floors and stable temperature help preserve both the tire casing and the sidewall finish.

Prewar cars often sit for long stretches, so tire care becomes more about time and environment than miles. If the 1927 Kissel will remain parked for months, some owners use tire cradles or support the car in a way that reduces sustained load on the same contact patch. Even when the car is stored indoors, check pressure periodically and look for sidewall drying or cracking before the next touring season.

Tires on a 1927 Kissel should be evaluated by age more than by mileage, because collector cars often cover few miles but still experience rubber aging. A good rule is to inspect them closely once they reach about five to seven years of service and to give serious replacement consideration as they approach roughly ten years, regardless of tread depth. The DOT date code on the tire helps establish age on modern reproduction products.

A prewar car can appear to have excellent tread and still be riding on aged rubber that has hardened or begun to crack internally. That is especially important on a heavy, substantial automobile such as a 1927 Kissel, where tire condition directly affects ride quality and confidence on the road. If the car's history is unclear, date the tires first and treat appearance alone as an incomplete measure of serviceability.

Tires on a 1927 Kissel deserve a quick inspection before every drive and a more thorough inspection before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, embedded debris, and any loss of air pressure. The valve area also deserves attention, especially on older wheels or cars that may use tubes depending on their wheel setup.

Frequent inspection matters because a low-use collector car can develop issues while parked, not just while being driven. A tire that looked fine at the end of last season can show weather checking or a pressure problem by the next start-up. Before taking a 1927 Kissel on a tour, also inspect the spare, because roadside support for prewar sizes is far less straightforward than it is for modern daily-driver tire sizes.

A 1927 Kissel 55 would have been fitted in the bias-ply era, and the two listed sizes for the year and make are 33X6.00 and 600-21. Both are period-appropriate bias-ply fitments for the late 1920s, and both also apply to the Kissel 75. Original-equipment branding can vary by market, dealer practice, and restoration history, so construction type and size format are usually the first authenticity checkpoints.

For restoration work, it is wise to confirm what was on your specific car through surviving photos, factory literature, old invoices, or marque-club knowledge rather than relying only on broad year-make fitment. The late-1920s transition between antique-style and numeric size conventions means the exact marking on the tire can matter almost as much as the wheel diameter. Matching the original style more closely will usually make the finished car look more coherent and convincing.

Correct tire fitment absolutely matters when showing a 1927 Kissel, especially in preservation, restoration, or concours settings where judges and knowledgeable spectators notice the relationship between tire size, construction, and sidewall appearance. On a car from 1927, bias-ply construction is in keeping with the era, and details such as blackwall versus wide whitewall can change whether the finished car looks historically consistent.

What counts as correct can vary by event, judging standard, and the exact presentation you are aiming for. A tire that fits mechanically may still look out of step if its size format or sidewall style does not suit the car's period image. Before finalizing a show-oriented 1927 Kissel, compare your intended tire choice against period photography and consult a Kissel club or event rulebook so the car's stance and sidewall treatment align with the standard being used.

For a 1927 Kissel in 600-21, Lester offers a blackwall classic bias-ply tire weighing 20 pounds, while BFGoodrich offers blackwall and 3.50-inch wide whitewall classic bias-ply versions weighing 31 and 34 pounds respectively. The BFGoodrich versions also list a maximum load capacity of 1350 pounds at 36 psi and specify a 3.00 to 3.75 inch rim width range. All of these choices remain within the same vintage 600-21 bias-ply size family.

That makes the comparison mostly about presentation and the level of specification detail you want to work from. A restorer seeking a formal luxury-car look may gravitate toward the BFGoodrich wide whitewall, while a simpler touring appearance points naturally toward a blackwall. Since all are intended for the same 1927 Kissel size, use the wheel's measured width and the car's visual goal as the two deciding factors rather than assuming the brand name alone settles the choice.

1927 Kissel tires can be suitable for highway use when they are the correct size, in sound condition, and maintained properly, but the available products shown here do not list speed ratings in their size markings. Because these are prewar bias-ply applications, overall road behavior is influenced as much by the car's own steering, braking, suspension, and wheel condition as by the tire itself. Mechanical condition matters greatly on an automobile of this age.

That means highway safety is less about chasing modern-style speed capability and more about realistic touring speeds, careful inspection, and proper setup. A well-sorted 1927 Kissel on fresh, correctly fitted tires can be enjoyable on public roads, but it should still be driven with the manners and margins appropriate to a late-1920s automobile. Before longer highway travel, make sure the full chassis, not just the tires, is prepared for sustained running.

Inflation pressure for 1927 Kissel tires should follow the tire manufacturer's rated limits and the vehicle's original recommendations rather than borrowing a number from a different size. In the listed 600-21 BFGoodrich products, the published load figure is 1350 pounds at 36 psi. That is a product rating reference, not a universal inflation instruction for every 1927 Kissel tire or every tire in both listed sizes.

The best practice is to start with the factory guidance for the car, then confirm that your chosen reproduction tire's rated pressure and load information align with the way the vehicle will actually be used. Older luxury cars often respond noticeably to even small pressure changes in ride and steering feel. Keep the front and rear pressures appropriate to the car's needs and avoid assuming that one 21-inch tire size should be inflated exactly like the other.

Before a longer drive in a 1927 Kissel, inspect each tire for cracking, cuts, bulges, irregular wear, and stable air pressure. Check the valve stems, verify that the spare is usable, and make sure the wheel hardware is secure and appropriate to the type of wheel on the car. A prewar touring car should also be reviewed beyond the tires, including brakes, steering, fluids, and cooling condition.

Longer runs place steady heat and load into a tire system that may spend much of the year parked. Even if the tread looks healthy, age, storage conditions, and prior restoration work can affect reliability once the car is driven for an extended period. Give yourself enough time for a short local test drive first, because a 1927 Kissel will often reveal pressure, balance, or chassis issues early if something in the overall setup needs attention.
