The 1934 Lafayette 6 Cyl. came from a period when independent makes and companion brands competed on style, value, and smooth road manners in a rapidly maturing American market. For owners preserving one today, tire choice matters because the car’s stance, visual character, and road feel are closely tied to its original-era sizing. This Lafayette uses a 550-17 bias-ply tire on a 17-inch rim. Available choices stay within that traditional format while allowing a different presentation through blackwall, wide whitewall, or double-whitewall styling. The real decision is how closely the tire should match the car’s restoration theme and intended driving use.
Which Tire Size Is Right for The 1934 Lafayette 6 Cyl.
The 1934 Lafayette 6 Cyl. uses one primary tire size: 550-17. It is a bias-ply fitment on a 17-inch rim, and the covered Base sub-model uses that same size, so the main choice is not between multiple primary sizes but between sidewall presentation and the kind of period-style look you want to maintain.
A 550-17 tire uses a vintage numeric bias-ply size code in which the 5.50 designates the nominal section width in inches and the 17 identifies the wheel diameter. On the 1934 Lafayette 6 Cyl., that means a traditional bias-ply fitment that suits the car’s prewar proportions and original-era tire construction. In this size, BFGoodrich options are available in the Silvertown Classic Bias Ply series with blackwall, wide whitewall, and double-whitewall sidewall treatments. Choosing among them comes down to the look you want on the car and confirming that your wheels remain true to the original 17-inch setup.
Tire fitment is straightforward across the covered 1934 Lafayette 6 Cyl. sub-models. The Base model uses the same 550-17 bias-ply size, so the focus shifts from size selection to sidewall style, restoration appearance, and wheel-condition verification.

Owners of a 1934 Lafayette 6 Cyl. usually need clarity on the 550-17 tire size, 17-inch rim fitment, bias-ply construction, sidewall appearance choices, and the checks worth making before putting a collector car back on the road.
Tire Size & Fitment
What tire size fits a 1934 Lafayette 6 Cyl.?
The 1934 Lafayette 6 Cyl. uses a 550-17 tire size. That is a vintage numeric bias-ply size mounted on a 17-inch rim, and it is the primary fitment for this application.
That single-size fitment simplifies the search, but the car should still be checked carefully before purchase. A collector vehicle may have replacement wheels, mixed wheel sets, or long-unused rims that need inspection, so confirming the actual 17-inch wheel diameter and overall wheel condition is still an important step before selecting a new 550-17 tire.
What size rim does a 1934 Lafayette 6 Cyl. use?
The 1934 Lafayette 6 Cyl. uses a 17-inch rim with its 550-17 tire size. The tire code itself ends in 17, and the tire fitment for this application centers on that wheel diameter.
Rim diameter is only part of the fitment picture on an older vehicle. The wheel should also be inspected for condition, trueness, bead-seat integrity, and compatibility with the intended bias-ply tire, especially if the car has been stored for years or restored with replacement wheels that may not match the original setup exactly.
Does the 1934 Lafayette 6 Cyl. Base use the same tire size?
Yes. The 1934 Lafayette 6 Cyl. Base uses the same 550-17 bias-ply tire size. That keeps fitment consistent within the covered application and avoids the need to sort through multiple primary sizes by trim.
Even with shared fitment, tire selection is not entirely automatic. The practical choice becomes which sidewall appearance best suits the car, whether blackwall, wide whitewall, or double-whitewall, while also confirming that the wheels on the car are still the proper 17-inch rims and have not been changed during earlier repairs or restoration work.
Choosing the Right Tire
What should I consider when choosing a 550-17 tire for a 1934 Lafayette 6 Cyl.?
Start with the correct primary size, which is 550-17, and stay mindful that this application uses a traditional bias-ply construction. Beyond size, the main differences are the tire’s visual presentation and how closely it matches the car’s restoration goals or intended road use.
A blackwall gives a more restrained look, while wide whitewall and double-whitewall versions create a stronger period-style presence. Wheel condition matters just as much as appearance on a prewar vehicle, so inspect the rims closely and consider how often the car is driven, how original the restoration is, and whether the tire choice is meant for show presentation or regular collector use.
What sidewall styles are available for 1934 Lafayette 6 Cyl. tires?
The available 550-17 tires for the 1934 Lafayette 6 Cyl. include blackwall, wide whitewall, and double-whitewall sidewall styles. Each option keeps the same vintage-size format and bias-ply construction while changing the visual character of the car.
That makes sidewall choice one of the biggest decisions for this application. A buyer focused on a restrained driver-style look may prefer blackwall, while a restoration-oriented owner may want the stronger visual statement of a whitewall treatment. When exact historical appearance matters, it is wise to compare the tire choice with period photos, marque references, or restoration documentation for the specific car.
What brands offer tires for the 1934 Lafayette 6 Cyl.?
BFGoodrich offers tires for the 1934 Lafayette 6 Cyl. in the 550-17 size. The available products are part of the Silvertown Classic Bias Ply series and stay within the proper vintage bias-ply construction for this application.
Since the brand choice here is focused rather than broad, comparison shifts to sidewall treatment and how the finished tire supports the car’s overall presentation. It is still worth checking the actual wheel setup on the car before ordering, because an older restoration, replacement rim, or mismatched spare can create fitment questions even when the tire size itself is straightforward.
Restoration & Appearance
Which tire should I choose for a period-style 1934 Lafayette 6 Cyl.?
A 550-17 bias-ply tire is the right starting point for a period-style 1934 Lafayette 6 Cyl. because it preserves the original-era sizing format and construction style used on the car. That keeps the stance and general visual character aligned with a prewar presentation.
The remaining decision is mostly about sidewall appearance. Blackwall creates a more understated look, while wide whitewall or double-whitewall versions give the car a stronger formal and restoration-oriented presence. If exact historical authenticity is important, compare the final choice against marque-club references, period photography, or restoration records tied to the specific vehicle.
How does tire construction affect the appearance of a restored 1934 Lafayette 6 Cyl.?
Tire construction has a noticeable effect on how a restored 1934 Lafayette 6 Cyl. sits and presents. A bias-ply tire keeps the car in a traditional prewar format, which helps preserve the kind of visual proportions and road-going character buyers usually expect from a restoration in this era.
Appearance is not only about the size code on the sidewall. The blackwall, wide whitewall, or double-whitewall treatment changes the car’s personality just as much, ranging from restrained to more formal and show-oriented. Before finalizing a set, look at the wheel finish, body color, trim level, and the overall restoration direction so the tire supports the whole presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1934 Lafayette 6 Cyl.?
Yes. Even though the primary tire size for a 1934 Lafayette 6 Cyl. is 550-17, later changes can alter what actually works on the car. Replacement wheels, brake updates, suspension work, or body and fender changes can all affect clearance and wheel compatibility.
That is especially important with older collector vehicles that may have passed through several owners over many decades. A close inspection of the actual wheel diameter, wheel width, steering clearance, and tire-to-fender space helps prevent surprises. The same check should include the spare, since it may not match the road wheels after previous repair or restoration work.
What should I inspect before driving a 1934 Lafayette 6 Cyl. on new tires?
Before driving a 1934 Lafayette 6 Cyl. on new tires, inspect the wheels, valve hardware, and the general condition of the mounting surfaces. The suspension, steering components, brakes, and alignment should also be checked, because fresh tires perform best when the rest of the chassis is ready for road use.
Tire condition matters after installation as well. Watch for proper inflation, even seating, sidewall damage, unusual vibration, and any sign of rubbing during low-speed turning. On a vehicle that has spent long periods parked, it also makes sense to look over wheel bearings and related wear items before heading out on regular drives or event mileage.
How should 550-17 tires on a collector 1934 Lafayette 6 Cyl. be maintained?
A set of 550-17 tires on a collector 1934 Lafayette 6 Cyl. should be maintained with regular pressure checks, visual inspections, and careful storage habits. Bias-ply tires on low-use vehicles still age even when tread wear is minimal, so condition should matter as much as miles traveled.
Look for cracking, flat-spotting, bulges, cuts, and slow air loss, especially after the car has been parked for extended periods. Storage away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires. It is also smart to inspect them before tours or longer drives, since collector cars often accumulate time in storage between outings.
