The 1933 Hupmobile K comes from an era when independent American automakers still competed on style, engineering character, and road presence. A surviving Hupmobile from this period is usually owned with preservation, restoration, or careful touring in mind, so tire choice affects both appearance and drivability in a very visible way. For this model, the primary fitment is a 6.00-17 bias-ply tire on a 17-inch rim. That keeps the decision focused less on size hunting and more on selecting the right period-style tire within the proper construction. Before putting the car back on the road, it also makes sense to confirm wheel condition, overall chassis health, and the kind of use the car will actually see.
Which Tire Size Is Right for The 1933 Hupmobile K
The 1933 Hupmobile K uses one primary tire size: 6.00-17. That is a numeric bias-ply size for a 17-inch rim, and the same fitment carries across the covered 6 Cyl. sub-model, so the main decision is choosing the right period-style tire within that size and making sure the wheel and vehicle setup remain compatible.
In a numeric bias-ply size like 6.00-17, the 6.00 refers to the tire's nominal section width in inches, while 17 identifies the rim diameter. This format is appropriate to the 1933 Hupmobile K's original-era tire construction and preserves the tall, traditional profile expected on a pre-war car. Tire selection in this size is usually centered on period-style appearance, restoration goals, and road-use expectations rather than choosing between multiple primary fitments. It is still worth confirming the actual wheel dimensions and the condition of the rims before mounting replacement tires.
Fitment is straightforward for the covered 1933 Hupmobile K sub-model. The same primary tire size is used here, so checking the sub-model mainly helps confirm that the car remains on its intended wheel and tire setup.

Frequently Asked Questions
Common 1933 Hupmobile K tire questions usually come down to understanding the 6.00-17 size, confirming 17-inch rim fitment, preserving a period-style appearance, and checking wheel, suspension, and tire condition before driving.
Tire Size & Fitment
What tire size fits a 1933 Hupmobile K?
The 1933 Hupmobile K uses a 6.00-17 tire size. This is a numeric bias-ply fitment, and it is the primary size associated with the model, including the covered 6 Cyl. sub-model.
That means the first step is not choosing between multiple original sizes, but confirming that the car still has the correct 17-inch wheels and a stock-type overall setup. On an older collector car, wheel replacements, long-ago repairs, or chassis modifications can change what is actually on the vehicle, so it is smart to inspect the wheels before selecting new tires.
What size rim does a 1933 Hupmobile K use?
The 1933 Hupmobile K uses a 17-inch rim with its 6.00-17 tire size. The rim diameter matters because the tire bead must match the wheel diameter exactly.
A 17-inch tire cannot be mounted safely on a different wheel diameter, even if the tire's overall look seems close. On a pre-war vehicle, it is also wise to check that the rim is true, free from serious corrosion or damage, and appropriate for the tire being installed before the car returns to regular road use.
Does the 1933 Hupmobile K 6 Cyl. use the same tire size?
Yes. The covered 1933 Hupmobile K 6 Cyl. uses the same 6.00-17 bias-ply tire size as the model core. That keeps fitment simple at the sub-model level.
Even with shared fitment, the car itself still needs to be checked carefully. Collector vehicles often accumulate replacement wheels, suspension work, or mixed-condition rims over the years, so matching the sub-model name alone is not enough. Verifying wheel diameter, wheel condition, and basic clearance helps avoid problems once the new tires are mounted.
Choosing the Right Tire
What should I consider when choosing a 6.00-17 tire for a 1933 Hupmobile K?
Start with the correct 6.00-17 size and bias-ply construction, since that is the primary fitment for the 1933 Hupmobile K. For a car from this era, the tire's overall presentation matters almost as much as the size because the tall profile is a visible part of the vehicle's character.
The next considerations are practical: inspect the wheel itself, think about whether the car is being restored, preserved, or driven on occasional tours, and choose a tire that suits that goal. A Hupmobile used mainly for show can be approached differently than one seeing regular road miles, but either way the wheel and chassis condition should be part of the decision.
How do I choose between the available 6.00-17 tires for a 1933 Hupmobile K?
Choosing among 6.00-17 tires for a 1933 Hupmobile K comes down to staying with the correct size while balancing appearance, construction authenticity, and intended use. Since there is one primary fitment, the comparison is usually about which tire best matches the character of the car rather than switching to another original size.
A restoration-oriented car may call for a tire that supports a more traditional visual presentation, while a regularly exercised car may place more emphasis on road manners and service condition. It also helps to compare the actual wheel setup on the car, because an old vehicle with changed wheels or uneven rim condition can affect which 6.00-17 choice makes the most sense.
What rim-fitment details should I compare when choosing 1933 Hupmobile K tires?
The most important rim-fitment detail for a 1933 Hupmobile K is the 17-inch wheel diameter required by the 6.00-17 tire size. Beyond diameter, the actual condition and dimensions of the wheel should be checked before any replacement tire is installed.
Older wheels can have wear, rust, prior repairs, or dimensional inconsistencies that matter just as much as the tire size on paper. It is also worth checking that the wheels match one another side to side and front to rear. That kind of inspection helps keep a pre-war car consistent in stance, clearance, and general drivability once fresh tires are fitted.
Restoration & Appearance
Which tire should I choose for a period-style 1933 Hupmobile K?
A period-style 1933 Hupmobile K should begin with the correct 6.00-17 bias-ply size. That sizing and construction preserve the traditional proportions associated with a pre-war American passenger car and provide the right starting point for a restoration-minded tire choice.
Appearance decisions should then be guided by the kind of restoration or preservation standard the car is following. When exact historical authenticity matters, marque references, period photographs, and vehicle-specific documentation are worth consulting. Even then, the practical side still matters, because a visually appropriate tire needs to be paired with sound wheels and a roadworthy chassis.
Does correct tire fitment matter for a 1933 Hupmobile K restoration?
Yes, correct tire fitment matters a great deal on a 1933 Hupmobile K restoration. The 6.00-17 size influences not just road use, but also the car's stance, visual balance, and the overall impression of an accurately presented pre-war vehicle.
Using the proper size helps the car look and sit as intended, but restoration fitment is not only about appearance. Wheel condition, suspension health, and the way the car will actually be driven should all be part of the process. A Hupmobile that looks right in the garage still needs dependable tire and wheel integrity before it is ready for the road.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1933 Hupmobile K?
Yes. Modifications can affect tire fitment on a 1933 Hupmobile K even when the intended tire size remains 6.00-17. Wheel substitutions, suspension work, altered ride height, brake conversions, or body repairs can all change the space available around the tire.
A collector car that has been rebuilt over many decades may not match its original wheel and chassis setup exactly. That makes it important to check steering clearance, fender clearance, and the actual wheel dimensions already on the car. Those inspections matter before choosing tires, not after, especially on a pre-war vehicle with specialized restoration history.
What should I inspect before driving a 1933 Hupmobile K on new tires?
Before driving a 1933 Hupmobile K on new tires, inspect the wheels, lug hardware, valve stems, and the condition of the suspension and steering components. Tire pressure should be set appropriately, and the tires themselves should be checked for proper seating and any visible issues after installation.
A short initial drive followed by a recheck is a sensible approach on an older car. Pay attention to air retention, vibration, rubbing, or changes in steering feel, since those can point to wheel condition or chassis issues rather than the tire alone. Pre-war cars reward careful inspection before longer road use.
How should 6.00-17 tires on a collector 1933 Hupmobile K be maintained?
6.00-17 tires on a collector 1933 Hupmobile K should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Even a low-mile car can develop sidewall cracking, flat spotting, air loss, or deterioration simply from long storage.
Storage conditions matter almost as much as mileage on a vehicle of this age. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition over time. It is also wise to inspect the tires before each outing rather than assuming that a seldom-driven Hupmobile is automatically ready for the road.
