The 1930 Pontiac 6 Cyl. sits in an interesting pre-war moment, when styling, road manners, and mechanical refinement were advancing quickly but tire sizing still reflected older conventions. Owners of these cars often balance authentic presentation with the realities of careful road use, especially on vehicles that now spend more time touring, showing, or preserving than commuting. For this Pontiac, the primary fitment centers on 19-inch bias-ply tires in 29X5.00 or 500-19 form. Available choices lean toward traditional blackwall presentation, including Excelsior and Firestone offerings with distinct series character. The key is confirming which period-style size language matches the wheel and intended use before selecting a tire.
Which Tire Size Is Right for The 1930 Pontiac 6 Cyl.
The 1930 Pontiac 6 Cyl. uses two primary tire size designations, and both are bias-ply fitments tied to a 19-inch wheel setup. Because the same sub-model can be associated with either size expression, the real task is confirming how the wheel and tire are marked and choosing the tire style that best suits restoration goals, road use, and the type of period presentation you want.
29X5.00 is an older tire format that expresses the tire by approximate overall diameter and section width, rather than by modern metric sizing. On a 1930 Pontiac 6 Cyl., it represents a traditional bias-ply fitment used on a 19-inch wheel arrangement even though the rim diameter is not embedded in the size code itself. This type of sizing is especially familiar on pre-war vehicles where earlier naming conventions remained common. It is the right size to evaluate when preserving an early-period look matters and when wheel markings and existing fitment should be matched carefully.
500-19 is a numeric bias-ply size in which the leading number refers to nominal section width and the final number identifies the 19-inch rim diameter. For the 1930 Pontiac 6 Cyl., this size provides a more explicit wheel reference than 29X5.00 while still staying within the period bias-ply fitment story. Available products in this size include blackwall options from Excelsior and Firestone, with series differences such as Comp H and Dirt Track. This is the size to focus on when comparing actual product choices, rim-width suitability, and intended driving character.
Fitment is straightforward here because the covered sub-model shares the same period bias-ply sizing path. Checking the exact sub-model still helps confirm that the tire size language on the car matches the replacement tire you are considering.

1930 Pontiac 6 Cyl. Base
The 1930 Pontiac 6 Cyl. Base is associated with the same two bias-ply size conventions used across this fitment, so the main question is not trim variation but which size expression matches the car's current wheel and tire setup. That makes tire selection more about preserving a traditional look and confirming wheel details before choosing among the available product styles.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1930 Pontiac 6 Cyl. Tires for Sale
Available 500-19 products give the 1930 Pontiac 6 Cyl. buyer a focused comparison between Excelsior and Firestone blackwall bias-ply tires. The main differences come from tire series, rim-width specifications, and whether the car is being equipped for restoration-style driving or a more specialized vintage performance presentation.
Common questions for the 1930 Pontiac 6 Cyl. usually center on interpreting 29X5.00 versus 500-19, confirming 19-inch wheel fitment, choosing among available blackwall bias-ply tires, and checking the car carefully before returning it to road use.
Tire Size & Fitment
What tire size fits a 1930 Pontiac 6 Cyl.?
The 1930 Pontiac 6 Cyl. uses two primary bias-ply size designations: 29X5.00 and 500-19. Those sizes reflect period tire naming conventions rather than modern metric sizing, and both belong to the same vintage fitment story for this vehicle.
The practical step is confirming how the tires and wheels on the car are actually marked. A pre-war vehicle may have replacement wheels, older restoration work, or mixed components, so matching the existing wheel diameter and the intended period-style size expression is more important than assuming every 1930 Pontiac 6 Cyl. is currently set up the same way.
What size rim does a 1930 Pontiac 6 Cyl. use?
The 1930 Pontiac 6 Cyl. uses a 19-inch rim with its primary tire fitment. That rim diameter is stated directly in the 500-19 size, while the 29X5.00 designation uses an older diameter-by-section format that does not spell out the wheel diameter in the same way.
Wheel diameter should still be verified on the car before ordering tires, especially on a vehicle this old. Replacement wheels, long-ago repairs, or previous restoration choices can change what is currently installed, and a 19-inch tire should only be selected after the wheel diameter and general wheel condition have been checked carefully.
Does the 1930 Pontiac 6 Cyl. Base use the same tire size?
Yes. The 1930 Pontiac 6 Cyl. Base is associated with the same two bias-ply size conventions used for this fitment: 29X5.00 and 500-19. There is no separate alternate sub-model tire size here that changes the basic fitment path.
That means the decision is less about trim level and more about matching the wheel and tire setup already on the car. On an older Pontiac, it is wise to inspect the wheels, compare the existing size markings, and make sure the selected tire supports the appearance and road-use expectations of the restoration or preservation plan.
Choosing the Right Tire
What should I consider when choosing a 500-19 tire for a 1930 Pontiac 6 Cyl.?
Start with the correct size, bias-ply construction, and 19-inch wheel fitment. From there, compare the available 500-19 options by brand, tire series, sidewall style, and rim-width suitability, since those factors shape how closely the tire matches the look and intended use of the car.
A restoration-oriented owner may focus first on traditional blackwall appearance and period character, while another buyer may pay closer attention to series type or more specialized use. It also helps to review wheel width, general vehicle setup, and whether the car is meant for display, casual touring, or vintage event use before settling on one tire.
What brands offer tires for the 1930 Pontiac 6 Cyl.?
In 500-19, the 1930 Pontiac 6 Cyl. has product options from Excelsior and Firestone. Both are bias-ply blackwall tires, but they differ by tire series and related product characteristics rather than by a change in the vehicle's basic fitment size.
Brand choice should be weighed alongside the tire's intended role on the car. Some owners want a straightforward traditional presentation, while others may be comparing a more specialized vintage performance-oriented design, so it makes sense to look past the brand name alone and consider wheel compatibility, use, and appearance together.
What tire series are available for the 1930 Pontiac 6 Cyl.?
The available 500-19 tire series for the 1930 Pontiac 6 Cyl. include Excelsior Comp H and Firestone Dirt Track. Both stay within the correct bias-ply size family, but the series names point to different product character and intended presentation.
Series matters because two tires in the same nominal size can still serve different ownership goals. A buyer trying to maintain a traditional road-car look may evaluate a tire differently than someone considering a more specialized vintage performance style, so the best comparison is size first, then series purpose, wheel suitability, and visual fit with the car.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Pontiac 6 Cyl.?
A period-style 1930 Pontiac 6 Cyl. should stay with the correct bias-ply fitment family, using 29X5.00 or 500-19 as the starting point. Those sizes preserve the pre-war sizing language and construction type that suit the vehicle's age and overall presentation.
From there, the right choice depends on how strictly the car is being restored and how it will be used. Buyers pursuing exact historical authenticity should compare the car against marque references or restoration documentation, while a general preservation approach can focus on correct size, blackwall appearance, and a tire that complements the vehicle's era.
Does correct tire fitment matter for a 1930 Pontiac 6 Cyl. restoration?
Yes, correct tire fitment matters on a 1930 Pontiac 6 Cyl. because the tire has a strong visual effect on a pre-war car's stance, proportions, and overall character. Size format and bias-ply construction both contribute to whether the finished vehicle looks appropriate for its era.
Fitment also affects how comfortably the restoration comes together in practical terms. A tire that matches the wheel correctly and respects the car's original style direction is less likely to create avoidable clearance or appearance issues, so tire selection should be treated as part of the restoration plan rather than as an afterthought.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Pontiac 6 Cyl.?
Yes. Modifications can affect tire fitment on a 1930 Pontiac 6 Cyl., especially if the car has replacement wheels, altered suspension components, brake changes, or body and fender work from an older restoration. Even when the intended tire size is correct, those changes can influence how the tire sits and clears.
A careful check should include wheel diameter, wheel width, and visible clearance at steering and suspension points. Pre-war vehicles often have long service histories, so it is smart to inspect the actual car rather than relying only on what should be there, particularly before mounting fresh bias-ply tires for road use.
What should I inspect before driving a 1930 Pontiac 6 Cyl. on new tires?
Before driving a 1930 Pontiac 6 Cyl. on new tires, inspect the wheels for damage or corrosion, confirm the tires are seated correctly, and check inflation, valve condition, and overall clearance. A quick visual review of steering components, suspension condition, and brake function is also worthwhile on a collector vehicle of this age.
Tires are only one part of getting a seldom-driven pre-war car back on the road. Roadworthiness improves when the rest of the chassis is checked for looseness, leaks, or wear, and a short low-speed test drive can help reveal rubbing, pull, vibration, or other issues before the car is taken on a longer outing.
How should 500-19 tires on a collector 1930 Pontiac 6 Cyl. be maintained?
500-19 tires on a collector 1930 Pontiac 6 Cyl. should be maintained with regular pressure checks, visual inspection for cracking, cuts, bulges, and uneven wear, and periodic rotation in service when appropriate. Collector cars that sit for long periods also benefit from clean storage conditions and routine checks for slow air loss.
Storage habits matter as much as mileage on an older car. Keeping the Pontiac away from prolonged sunlight, excess moisture, and ozone sources helps preserve tire condition, and it is wise to inspect the tires before every meaningful drive because age, storage, and inactivity can affect a collector vehicle long before tread wear becomes the issue.
