1934 Pontiac sat in the heart of the prewar American market, offering stylish, value-minded cars with a stronger, more upscale presence than many buyers expected at the price. By this period, Pontiac had established itself as a key General Motors marque, and its eight-cylinder offerings gave buyers a smooth-running alternative in an increasingly competitive field. For 1934 Pontiac, the tire picture is refreshingly straightforward: one model core uses one size, 6.00-17, in bias-ply construction. That makes the first step simple but still important, because the right choice comes down to confirming you have a 1934 Pontiac 8 Cyl. and matching the tire to the correct 17-inch wheel.
Which Tire Size Is Right for Your 1934 Pontiac
One tire size is available for 1934 Pontiac vehicles, and it is used by the full model range covered here. The main decision is not between multiple fitment paths, but between products within the same period-correct bias-ply size, starting with confirmation of the correct 17-inch rim. Understanding that distinction before choosing a product saves time and helps match the tire to the car.
Year(s): 1934|Fit(s): 8 Cyl.|Construction: Bias Ply|Rim: 17-in rim
6.00-17 is a numeric bias-ply size in which 6.00 represents the nominal section width in inches and 17 identifies the wheel diameter. Available products in this size span brands including Firestone, BFGoodrich, and US Royal, with sidewall styles that include blackwall and whitewall. It is the correct year-and-make size for the 1934 Pontiac 8 Cyl., so the practical choice is usually about restoration character and sidewall appearance rather than changing fitment.
One model core is covered for 1934 Pontiac. Because the year uses a single tire size across the model range here, the focus is less about sorting through multiple fitments and more about selecting the right bias-ply product for the car's restoration style and road use. Select the model below for model-specific fitment history and products.
1934 Pontiac 8 Cyl.
The 1934 Pontiac 8 Cyl. represented Pontiac's effort to give mid-priced buyers a smoother, more prestigious driving experience during the prewar era. Its tire fitment centers on a 17-inch wheel, which suits the tall, proper stance expected of an American car from this period. Buyers usually narrow the choice by sidewall appearance and intended authenticity level rather than by switching between multiple tire sizes.
These FAQs cover the single 6.00-17 fitment used on 1934 Pontiac, what that size code means, how to think about sidewall appearance and brand choice, and the storage and road-use checks that matter on a prewar collector car.
Size Basics & Fitment
What tire sizes fit 1934 Pontiac vehicles?
1934 Pontiac vehicles covered here use one tire size: 6.00-17. That size applies to the 1934 Pontiac 8 Cyl., and it is a bias-ply fitment built for a 17-inch wheel. Because there is only one size in the year-and-make range, buyers are not choosing between multiple rim diameters or alternate section widths at this level.
That simplicity helps narrow the search quickly, but it is still smart to confirm the actual wheel before choosing a tire, especially on a car that may have seen decades of service or restoration work. Once the 17-inch wheel is verified, the next decision is usually sidewall appearance and brand character rather than a change in nominal size.
What does 6.00-17 mean on a 1934 Pontiac tire?
On a 1934 Pontiac tire, 6.00-17 is a numeric bias-ply size. The 6.00 refers to the tire's nominal section width in inches, and the 17 refers to the wheel diameter in inches. It is an older sizing convention typical of the prewar era, and it does not read like modern metric radial sizing.
Knowing how to read that code helps prevent one of the most common ordering mistakes: confusing a vintage numeric size with a later alphanumeric or metric format. For a 1934 Pontiac, the key point is that the tire is meant for a 17-inch wheel and should be chosen as a proper bias-ply application for the car's period-correct proportions.
Do all 1934 Pontiac models use the same tire size?
Within the 1934 Pontiac range covered here, yes. The 1934 Pontiac 8 Cyl. uses 6.00-17, so there is no split in tire sizing across multiple model cores on this page. That makes year and make selection more straightforward than on many later lineups where body style or trim can change wheel and tire dimensions.
Even with a shared size, it is still worth confirming the exact model and checking the wheels already on the car. Older Pontiacs can pass through many hands over the decades, and replacement wheels are not unusual on collector vehicles. Verifying the wheel before final selection keeps the fitment process clean and avoids chasing the wrong vintage size.
Buying the Right Tire
What sidewall styles are available for 1934 Pontiac tires?
1934 Pontiac tires in 6.00-17 are available with both blackwall and whitewall sidewall styles. That gives owners a meaningful visual choice even though the size itself remains the same. On a prewar American car, sidewall appearance has a strong effect on the car's overall stance and whether the finished look feels more formal, restrained, or upscale.
Whitewalls are often chosen when the goal is a more dressed-up period presentation, while blackwalls suit a simpler or more utilitarian visual approach. The right answer depends on how the car is being restored and how it will be judged or displayed. If authenticity is the priority, compare the sidewall style to period photos, club references, and the car's intended presentation standard.
What brands make tires for 1934 Pontiac vehicles?
Three brands serve the 1934 Pontiac 6.00-17 fitment: Firestone, BFGoodrich, and US Royal. All are offered in the same vintage-style bias-ply size, so the basic fitment path remains consistent across brands. The choice is not about changing the Pontiac to a different tire format, but about selecting the brand presentation and sidewall treatment that best suits the car.
For many owners, brand choice comes down to restoration taste and visual fidelity to the era. Some buyers prefer a marquee American heritage name that complements a prewar GM product, while others focus on a particular tread or sidewall look. Since the size remains fixed at 6.00-17, compare the brand options with the specific appearance you want the finished 1934 Pontiac to carry.
How do I choose the right 6.00-17 tire for a 1934 Pontiac?
Choosing the right 6.00-17 tire for a 1934 Pontiac starts with three things: confirm the car is the 1934 Pontiac 8 Cyl., confirm it is on the proper 17-inch wheel, and decide what sidewall style best suits the car. The fitment itself is straightforward because the year and model covered here use one size and one construction type: bias-ply.
After that, narrow the choice by the car's mission. A formal restoration may point you toward the brand and sidewall look that best matches period expectations, while a driver-focused collector may simply want a clean, era-appropriate bias-ply presentation. Looking at the wheel, the car's finish level, and the intended use together will usually make the right 6.00-17 option clear.
Fitting & Setup
Do 1934 Pontiac tires require inner tubes?
1934 Pontiac tires use a prewar bias-ply fitment, and inner-tube use should be confirmed against the specific tire's sidewall marking and the wheel being used. Vintage-style applications from this era often involve tube-type setups, especially when original-style wheels are retained. The safest path is to match the tire, tube, flap if required, and wheel condition as a complete assembly rather than treating them as separate choices.
Wheel age matters just as much as tire size on a 1934 Pontiac. Before final assembly, inspect the rim for corrosion, rough edges, and any distortion that could affect sealing or tube life. If the car still carries older restored wheels, a marque specialist or experienced vintage tire installer can help confirm the correct setup and avoid pinched tubes, chafing, or poor bead seating.
What rim width do 1934 Pontiac tires require?
The 1934 Pontiac fitment shown here is built around a 17-inch wheel, since 6.00-17 identifies a tire for a 17-inch rim. Rim width still matters for proper section shape, sidewall behavior, and bead seating, but the first fitment checkpoint is always the wheel diameter itself. On an older car, that verification is especially important because wheel swaps can happen over many decades.
Once the 17-inch diameter is confirmed, compare the actual wheel to the tire maker's approved fitment guidance for the exact product you are considering. That step is more useful than assuming every old 17-inch wheel is interchangeable. A correct vintage tire can still perform poorly if mounted on a wheel that is too narrow, too wide, or in poor structural condition.
Maintenance, Storage & Longevity
How should I store a 1934 Pontiac when the tires are fitted?
A 1934 Pontiac should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that accelerate rubber aging. Bias-ply tires also tend to flat-spot more readily than modern radials when the car sits in one position for long periods. Clean floors, stable temperatures, and protection from standing moisture all help preserve both the tires and the wheels.
If the car will sit for an extended season, keep the tires properly inflated and move the car occasionally to change the contact patch. Some owners also use stands to reduce sustained load, but the car should be supported carefully and safely. Storage habits make a visible difference on a prewar Pontiac because sidewall cracking and set-in flat spots can spoil both appearance and drivability.
How long do tires on a 1934 Pontiac typically last?
On a 1934 Pontiac collector car, tire age matters more than mileage. A good rule is to evaluate the tires closely once they reach about five to seven years of age and to treat roughly ten years as a serious replacement threshold, even if the tread still looks presentable. Collector vehicles often accumulate few miles, but time, heat cycles, and storage conditions still age the casing and sidewall.
The practical move is to check the tire's manufacturing date code and judge the tire as an aging rubber product, not just as a treaded component. A lightly driven Pontiac that looks fine at a glance can still be running on rubber that has hardened or begun to crack internally. Replacing on age rather than waiting for obvious failure is the more prudent habit with prewar cars.
How often should tires on a 1934 Pontiac be inspected?
Tires on a 1934 Pontiac should be inspected before every drive, and they deserve a more thorough check before any extended outing. Look for sidewall cracking, cuts, bulges, unusual tread wear, and loss of air pressure. On an older bias-ply application, it is also wise to check valve stems and pay attention to any signs that the wheel or tube setup may need attention.
Frequent inspection matters because collector cars can spend long periods parked between drives, and problems often develop while the car is sitting rather than while it is being used. A short walk-around catches most visible issues before they become roadside problems. On a 1934 Pontiac, that routine should include the spare as well, since it may be the only practical backup on a longer trip.
Restoration & Authenticity
What tires were originally fitted to the 1934 Pontiac 8 Cyl.?
A 1934 Pontiac 8 Cyl. would have been fitted in the bias-ply era, and the size used here is 6.00-17. That aligns with what buyers expect on a mid-1930s American car, when bias-ply construction was standard and modern radial sizing was still far in the future. The essential original-equipment character is therefore a tall 17-inch bias-ply tire in the proper vintage numeric format.
For a factory-style restoration, construction type, size, and sidewall appearance matter more than guessing at a specific original tire brand. Market variations, dealer practices, and later wheel changes can complicate exact originality claims on any prewar car. If your Pontiac is being judged closely, compare your chosen tire against marque-club guidance, period photos, and event-specific standards before finalizing the fitment.
Does correct tire fitment matter for showing a 1934 Pontiac?
Correct tire fitment absolutely matters when showing a 1934 Pontiac. Judges and knowledgeable enthusiasts often notice whether the size, construction type, overall profile, and sidewall style suit the period. On a prewar American car, a visibly modern-looking tire can change the entire character of the vehicle, even if the wheel diameter itself is technically compatible.
A proper 6.00-17 bias-ply keeps the Pontiac's stance and visual proportions in line with the era. Sidewall choice also plays into authenticity, since a formal restoration may call for a different presentation than a simpler preservation car. If concours accuracy is the goal, align the tire selection with the judging rules and the historical look expected for a 1934 Pontiac rather than choosing by appearance alone.
How important is sidewall appearance on a 1934 Pontiac restoration?
Sidewall appearance is a major visual detail on a 1934 Pontiac restoration because the tire occupies a large part of the car's profile. In 6.00-17, both blackwall and whitewall options are available, and each gives the car a noticeably different period impression. On a prewar body with tall tires and substantial fender openings, that difference is more pronounced than many first-time restorers expect.
The best choice depends on the style of restoration you are pursuing. A more formal, upscale presentation may favor one look, while a simpler, more restrained finish may favor the other. Before committing, compare the tire's sidewall treatment to period photography, surviving cars, and club guidance so the final result supports the way you want the 1934 Pontiac to be interpreted.
Safety & Road Use
Are 1934 Pontiac tires safe for highway driving?
A properly fitted, correctly inflated 6.00-17 bias-ply tire in sound condition can be used for normal road driving on a 1934 Pontiac, but safe use depends on far more than tread depth alone. Bias-ply tires have different handling behavior than modern radials, and a prewar car also brings older steering, braking, and suspension expectations into the equation. The tire must be judged as part of the whole vehicle, not in isolation.
For practical driving, the key is to respect the car's age and drive within the limits of both the tire and the vehicle's underlying chassis. A careful pre-drive inspection, proper inflation, and realistic cruising expectations matter more on a 1934 Pontiac than chasing modern-car behavior. If the car has been stored for long periods, inspect age and sidewall condition before planning sustained highway use.
What inflation pressure should I use for 1934 Pontiac tires?
Inflation pressure for 1934 Pontiac tires should be set with two references in mind: the factory recommendation for the car and the tire manufacturer's guidance for the specific 6.00-17 product you are using. Those are not interchangeable ideas, because an original-era vehicle specification and a modern reproduction tire's rated limits serve different purposes. Pressure should never be guessed from appearance alone.
Start with the vehicle reference for operating pressure, then confirm that the chosen tire is being used within its own stated limits. Avoid borrowing pressure numbers from another size or another car just because the tires look similar. On a 1934 Pontiac, correct inflation affects ride height, steering feel, tread wear, and overall road manners more noticeably than many owners expect from a collector vehicle.
What should I check before taking a 1934 Pontiac on a longer drive?
Before a longer drive in a 1934 Pontiac, inspect each tire for cracking, cuts, bulges, uneven wear, and pressure loss, and look over the valve stems and spare as part of the same routine. Since this is a prewar bias-ply application, also pay attention to how the car has been stored and whether the tires have developed flat spotting. A vintage tire that appears acceptable at rest can reveal problems once the car is moving.
That tire check should be one part of a broader pre-drive inspection that includes brakes, steering, wheel fasteners, and fluid levels. Older cars ask more from the owner than a modern daily driver, and tires are only one element of road readiness. Giving the Pontiac a thoughtful inspection before departure greatly improves the odds of a smooth, uneventful trip.
