The 1930 Nash 6 Cyl. comes from an era when tire choice was closely tied to body style, passenger capacity, and the visual character of the car itself. For owners restoring or maintaining one today, getting the tire size right is as important as preserving the proper stance and road presence. This Nash uses bias-ply fitments in two 19-inch sizes, with 600-19 and 550-19 depending on the sub-model. Available choices include blackwall and wide whitewall presentations, giving the car either a more restrained or more formal period-style look. The key step is confirming the exact sub-model before choosing a tire for appearance, fitment, and intended road use.
Which Tire Size Is Right for The 1930 Nash 6 Cyl.
The 1930 Nash 6 Cyl. uses two primary tire sizes, and the correct one depends on the specific sub-model. Both are bias-ply tires for 19-inch rims, so the first step is confirming whether the car is the 7 Passenger model or the Base model before comparing sidewall style, tire series, and overall presentation.
A 600-19 size uses a numeric bias-ply designation in which the leading number represents an approximate 6.00-inch nominal section width, while the 19 identifies the wheel diameter. On the 1930 Nash 6 Cyl., this is a traditional bias-ply fitment that suits the car's pre-war driving character and appearance. In this size, the available option uses a wide whitewall treatment in the Lester Classic Bias Ply series, giving the car a notably formal and restoration-oriented look. It is the size to evaluate for the 7 Passenger configuration, with wheel condition and actual vehicle setup worth confirming before installation.
A 550-19 tire follows the same numeric bias-ply system, with the 5.50 indicating an approximate 5.50-inch nominal section width and the 19 indicating rim diameter. This size keeps the 1930 Nash 6 Cyl. in its original bias-ply construction style rather than shifting the car toward a later radial format. Available choices include BFGoodrich options in both blackwall and wide whitewall form within the Silvertown Classic Bias Ply series. It is the size associated with the Base model, making it the right starting point for buyers balancing period-style appearance with correct sub-model fitment.
Sub-model fitment matters on the 1930 Nash 6 Cyl. because the covered versions do not all use the same tire size. Both use 19-inch bias-ply tires, but identifying the exact sub-model comes first so the correct width and overall presentation can be chosen.

1930 Nash 6 Cyl. (7 Passenger)
The 1930 Nash 6 Cyl. (7 Passenger) uses the 600-19 bias-ply size on a 19-inch rim. That makes tire selection more about choosing the proper period-style appearance and confirming wheel condition than sorting through multiple primary fitments.
The 1930 Nash 6 Cyl. Base uses the narrower 550-19 bias-ply size on a 19-inch rim. In this version, the main choice is between blackwall and wide whitewall presentation while staying with the proper sub-model tire size.
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 Nash 6 Cyl. Tires for Sale
Available 1930 Nash 6 Cyl. tires focus on traditional bias-ply construction, with BFGoodrich and Lester offerings across Silvertown Classic Bias Ply and Lester Classic Bias Ply lines. Choices differ mainly by size, sidewall style, and the visual effect of blackwall versus wide whitewall presentation.
Common 1930 Nash 6 Cyl. tire questions usually center on the correct sub-model size, 19-inch rim fitment, bias-ply construction, sidewall appearance, and the checks worth making before putting a collector car back on the road.
Tire Size & Fitment
What tire size fits a 1930 Nash 6 Cyl.?
The 1930 Nash 6 Cyl. uses two primary tire sizes: 600-19 and 550-19. The 7 Passenger model uses 600-19, while the Base model uses 550-19, and both are bias-ply tires for 19-inch rims.
That means the first decision is not brand or sidewall style, but confirming which sub-model the car actually is. Once that is established, the correct size can be matched to the wheel and then narrowed down by appearance details such as blackwall or wide whitewall.
What size rim does a 1930 Nash 6 Cyl. use?
The covered 1930 Nash 6 Cyl. fitments use a 19-inch rim. Both primary tire sizes, 600-19 and 550-19, are built around that same rim diameter even though the tire widths differ by sub-model.
Rim diameter is only one part of the fitment picture on an early car like this. It still helps to confirm the wheel itself is the correct 19-inch type for the vehicle, in sound condition, and appropriate for the tire size being installed before the car returns to road use.
Why does the 1930 Nash 6 Cyl. have more than one tire size?
The two tire sizes exist because the covered sub-models do not share the same fitment. The 7 Passenger model uses 600-19, while the Base model uses 550-19, so tire selection changes with the exact version of the car.
That difference is important because both sizes may appear visually similar at a glance, yet they are not the same fitment choice. Checking the sub-model first helps preserve the car's intended stance and avoids choosing a tire simply because it has the correct 19-inch rim diameter.
Choosing the Right Tire
What should I consider when choosing a 1930 Nash 6 Cyl. tire?
Start with the correct sub-model size, since the 1930 Nash 6 Cyl. uses either 600-19 or 550-19 depending on configuration. Both are bias-ply 19-inch fitments, so the core decision is choosing the right size first and then selecting the appearance that best suits the car.
After size is confirmed, compare sidewall style, tire series, and wheel compatibility. A blackwall can give a simpler period look, while a wide whitewall creates a more formal presentation, and collector-car owners should also inspect wheel condition, age-related tire concerns, and intended driving use.
What sidewall styles are available for 1930 Nash 6 Cyl. tires?
Sidewall choices for the 1930 Nash 6 Cyl. include blackwall and wide whitewall, depending on tire size. The 550-19 BFGoodrich options are available in both blackwall and wide whitewall, while the 600-19 Lester option uses a wide whitewall presentation.
That gives buyers a meaningful appearance choice without changing away from the proper bias-ply format. Sidewall style can strongly influence how a pre-war car looks, so it is worth deciding whether the goal is a more understated road look or a more formal restoration-oriented presentation.
What brands offer tires for the 1930 Nash 6 Cyl.?
The 1930 Nash 6 Cyl. has available tires from BFGoodrich and Lester. BFGoodrich appears in the 550-19 size through the Silvertown Classic Bias Ply line, while Lester offers a 600-19 option in the Lester Classic Bias Ply series.
Brand choice should come after confirming the correct size for the specific sub-model. Once the fitment is settled, compare each option by sidewall treatment, series character, and wheel suitability rather than assuming a brand name alone determines the right tire for the car.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Nash 6 Cyl.?
A period-style starting point for a 1930 Nash 6 Cyl. is the correct bias-ply size for the sub-model: 600-19 for the 7 Passenger model or 550-19 for the Base model. Staying with the proper size and construction preserves the car's traditional stance and visual balance.
From there, the appearance choice usually comes down to sidewall treatment. Buyers focused on restoration detail should compare blackwall versus wide whitewall carefully and, when exact originality matters, consult marque references or vehicle-specific history before treating any one presentation as unquestionably authentic.
Does correct tire fitment matter for a 1930 Nash 6 Cyl. restoration?
Correct tire fitment matters on a 1930 Nash 6 Cyl. because tire width, construction, and sidewall style all influence how the car sits and how complete the restoration looks. Using the proper 600-19 or 550-19 bias-ply size keeps the car visually consistent with its era.
Fitment also affects practical details beyond appearance. The right size helps maintain intended proportions at the wheel opening, while the wrong size can change the car's presentation even if it mounts to a 19-inch rim, so sub-model verification is a key restoration step.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Nash 6 Cyl.?
Yes, modifications can affect tire fitment on a 1930 Nash 6 Cyl., even when the nominal tire size seems correct. Changes to wheels, suspension height, brake components, or body clearances can alter how a 600-19 or 550-19 tire sits and moves through its steering range.
A modified car should be checked more carefully than an untouched one. Wheel diameter, wheel width, and clearance at the fender, suspension, and steering components all matter, especially on an early vehicle where replacement parts and past repairs may have changed the original setup.
What should I inspect before driving a 1930 Nash 6 Cyl. on new tires?
Before driving a 1930 Nash 6 Cyl. on new tires, inspect the wheels for damage or corrosion, confirm the tires match the car's correct sub-model size, and make sure each tire is seated and inflated properly. It is also wise to check overall suspension and steering condition.
A collector car can have problems that are unrelated to the new tires themselves. Brake condition, wheel hardware, alignment, and any signs of rubbing should be reviewed before regular road use, since an early car may have sat for long periods or received non-original parts over time.
How should 600-19 and 550-19 tires on a collector 1930 Nash 6 Cyl. be maintained?
Collector-car tires in 600-19 and 550-19 should be maintained with regular pressure checks, visual inspection of the sidewalls and tread, and routine monitoring for cracking, cuts, bulges, or air loss. Long periods of storage make condition checks especially important on a 1930 Nash 6 Cyl.
Storage environment matters almost as much as mileage on a low-use car. Keeping the Nash away from prolonged heat, direct sunlight, moisture, and ozone sources can help preserve the tires, and occasional inspections of wheel condition and clearance remain worthwhile even when the car is driven sparingly.
