Kissel 73 Tires

Kissel 73 uses two tire sizes across the years covered here. The 1929 Kissel 73 appears with either 30X6.00 or 6.00-18, while the 1930 Kissel 73 uses 6.00-18. The 30X6.00 size corresponds to a 20-inch rim, and 6.00-18 corresponds to an 18-inch rim.

The practical step is to identify the car by both year and wheel size, not by year alone. A 1929 Kissel 73 can fall into either fitment, so the wheel itself needs to be checked before choosing tires. Once the rim diameter is confirmed, the correct size becomes much easier to narrow down.

On a Kissel 73, 30X6.00 is an antique diameter-by-section tire size. The first number, 30, is the overall outside diameter of the inflated tire in inches, and 6.00 is the nominal section width. It does not mean the tire fits a 30-inch wheel; the associated rim diameter is 20 inches.

That distinction matters because modern buyers often assume the first number is the wheel size. On a Kissel 73, selecting 30X6.00 without checking the wheel can lead to ordering the wrong fitment entirely. If your car has 18-inch rims, the correct direction is the later 6.00-18 size rather than the antique-style 30X6.00.

The 1929 Kissel 73 has two tire sizes listed because that year includes a rim diameter split. One application uses 30X6.00 on a 20-inch rim, while the other uses 6.00-18 on an 18-inch rim. The difference is not just wording on the sidewall; it reflects two distinct wheel diameters.

A 1929 owner should start by measuring or verifying the wheel before comparing tire options. Looking only at the model year is not enough for this particular car. Once the rim diameter is confirmed, you can match the tire size correctly and avoid confusing the antique size code with the later numeric size.

Kissel 73 uses two rim diameters across the years shown here: 20 inches and 18 inches. The 30X6.00 application in 1929 uses a 20-inch rim, while the 6.00-18 application used in 1929 and 1930 uses an 18-inch rim. That means the change to the smaller rim diameter appears during 1929.

Because 30X6.00 is an antique size, the wheel diameter cannot be read directly from the first number in the code. Owners should verify the rim on the car itself before selecting tires. That one check usually resolves the biggest fitment question on a Kissel 73.

Start with the model year, then confirm the wheel diameter on the actual Kissel 73. A 1930 Kissel 73 uses 6.00-18, but a 1929 Kissel 73 may use either 30X6.00 or 6.00-18 depending on whether the car carries 20-inch or 18-inch rims. That wheel check is the key step on this model.

Original literature, restoration records, and marque expertise can help if the car has had wheels changed over time. Measuring the rim directly is often the most reliable approach on an unrestored or long-stored car. Once the rim diameter is known, you can match the size code with much more confidence.

Kissel 73 fitment here spans two different sizing traditions rather than a long list of modern-style tire families. The earlier 30X6.00 uses an antique diameter-by-section convention tied to a 20-inch rim, while 6.00-18 uses the later numeric bias-ply convention tied to an 18-inch rim. The main difference is how the tire is sized and the wheel it fits.

For a buyer, that means the first decision is not tread style or appearance but which wheel diameter the car carries. A 20-inch wheel points you toward the antique-style size, while an 18-inch wheel points you toward the numeric bias-ply size. Matching the right sizing system to the right rim is more important here than comparing names alone.

A Kissel 73 owner should verify the model year, the actual rim diameter, and the size format used on the car. The critical split is between 30X6.00 on a 20-inch rim and 6.00-18 on an 18-inch rim. Both sizes appear in 1929, so the wheel itself matters as much as the year.

It is also wise to inspect whether the wheels are original to the car or were changed during earlier restoration work. Collector cars sometimes pick up non-original rims over the decades, which can make a year-based assumption misleading. Treat the size listing as the starting point and the wheel measurement as the deciding check.

A stored Kissel 73 should be kept in a cool, dry, dark environment away from direct sunlight, electric motors, ozone sources, and petroleum contamination. Tires on collector cars age more from time and environment than from mileage, especially when the car spends long periods parked. Clean floors, stable temperatures, and proper inflation all help preserve the casing.

If the Kissel 73 will sit for extended periods, move it occasionally to avoid flat spotting and concentrated stress in one footprint. Long-term storage is easier on the tires if the vehicle weight is reduced with stands placed correctly under the chassis. Period cars also benefit from regular visual checks for sidewall cracking, tread separation, and tube-related air loss.

Tires on a Kissel 73 should be inspected before each drive and more thoroughly at regular service intervals, even if the car covers very few miles. A brief pre-drive check should include inflation, visible cracking, cuts, bulges, loose valve hardware, and any sign that the tire has shifted on the rim. Low-use collector cars often reveal age-related issues before they show tread wear.

A more detailed inspection by a shop familiar with older wheels, tube-type assemblies, and vintage bias-ply construction is a good habit at least once a season. That is especially important if the car has been stored for years or is newly returned to service. Catching a casing problem early is far easier than dealing with a roadside failure in a pre-war automobile.

Tires on a Kissel 73 should be replaced when age, cracking, hardening, separation, repeated air loss, or structural damage appears, even if the tread still looks usable. Tread depth alone is not a reliable measure on a collector car because the tires may age out long before they wear out. Any tire that has spent decades mounted, stored poorly, or sitting flat deserves close scrutiny.

Pre-war cars place a premium on cautious inspection because their driving dynamics and braking distances leave less margin for tire trouble. If there is any question about the condition of an older tire, replacement is the conservative path. That approach protects both the car and the people riding in a vehicle that was designed for a very different era of road use.

Kissel 73 appears here with 30X6.00 in 1929 and 6.00-18 in 1929 and 1930, showing that more than one period-appropriate fitment existed during this short production run. The key distinction is wheel diameter: 30X6.00 pairs with a 20-inch rim, while 6.00-18 pairs with an 18-inch rim. That means originality depends on the specific year and wheel setup of the individual car.

For restoration work, the best approach is to match the tire size to surviving wheels, factory literature, and established marque references for that particular chassis. A 1929 Kissel 73 especially deserves careful checking because both fitments appear in the same year. Getting that detail right helps preserve the car's visual stance as well as its historical accuracy.

Correct tire fitment can absolutely affect how a Kissel 73 is judged and how convincingly the restoration presents. Vintage cars are evaluated as complete objects, and wheel diameter, tire profile, and overall stance all contribute to whether the car looks authentic for its period. A visibly incorrect rim-and-tire combination can stand out even to casual observers.

For owners pursuing serious show judging, marque clubs and established restoration references remain the best arbiters of what is appropriate for a given Kissel 73. Even outside judged competition, proper tire fitment supports the proportions the car was meant to carry. It is one of the few details that affects appearance, drivability, and historical credibility all at once.

A correct sidewall style for a Kissel 73 restoration should follow the car's period character and the exact tire line chosen for the proper size. Late 1920s and early 1930s cars can vary in presentation depending on how the vehicle is being restored, from restrained touring use to more formal show presentation. The sidewall look should complement the wheel diameter and tire profile the car actually uses.

Because 1929 Kissel 73 fitment can fall into either a 20-inch or 18-inch application, the first restoration step is still confirming the wheel before settling on appearance details. Owners concerned with authenticity usually compare surviving photos, literature, and marque guidance for similar cars. That prevents a visually attractive tire from undermining an otherwise accurate restoration.

A properly fitted, correctly installed tire can make a Kissel 73 usable for careful collector-car driving, but safety depends on the entire vehicle, not the tires alone. Wheel condition, tube installation, brake performance, steering play, suspension integrity, and long-stored mechanical components all matter on a pre-war automobile. A correct size is only one part of the equation.

Public-road use should be approached conservatively, with speeds and distances matched to the car's era and condition. A recently revived Kissel 73 deserves a full mechanical review before regular driving. Even with fresh tires, these cars should be treated as historic machinery rather than as modern transportation.

Before driving a Kissel 73, check tire inflation, visible sidewall condition, valve stems, wheel fasteners, and any sign of casing damage or tread separation. On an older car, it is equally important to inspect brakes, steering response, wheel bearings, and fluid leaks before moving the car onto the road. A short walk-around often reveals issues that have developed during storage.

For a Kissel 73, the smartest routine is to think like a caretaker rather than a commuter. Slow, deliberate pre-drive checks reduce the chance of discovering a problem at speed. That habit is especially valuable on cars with tube-type tires and wheels that may have seen decades of intermittent use.

A Kissel 73 should be driven at conservative speeds that respect both the age of the design and the condition of the individual car. Even when fitted with the correct size tires, a late 1920s or early 1930s automobile does not behave like a modern vehicle in braking, steering, or emergency maneuvers. The right pace is one that leaves generous stopping distance and avoids sustained high-speed running.

Owners should let road conditions, mechanical condition, and tire condition set the limit rather than traffic flow alone. Short pleasure drives, tours with sympathetic pace, and event use are more appropriate than pushing the car hard. If the Kissel 73 has just returned to service after long storage, begin with very modest speeds until the whole car proves itself.
