1955 Kaiser Manhattan Tires

The 1955 Kaiser Manhattan uses a 670-15 tire size. This is a vintage numeric bias-ply fitment used on a 15-inch rim, and the covered 6-cylinder Manhattan application uses that same primary size.

That means the first step is usually simple: start with 670-15 rather than sorting through multiple original sizes. From there, the real choice becomes sidewall style, brand, and whether to remain with the original-style bias-ply construction or evaluate one of the available radial-equivalent alternatives after confirming wheel width and vehicle clearance.

The 1955 Kaiser Manhattan uses a 15-inch rim with its primary 670-15 tire fitment. Product offerings in this size show several rim-width specifications, so wheel width matters along with diameter when comparing tire choices.

Diameter is the basic starting point, but it is not the only measurement worth checking. A car that has had wheel changes over the years may still have a 15-inch rim while using a different width than expected, which can affect bias-ply selection and any move to a radial equivalent. Measuring the actual wheel before ordering helps avoid an appearance or clearance mismatch.

Yes. The covered 1955 Kaiser Manhattan 6 Cyl. application uses the same 670-15 bias-ply tire size as the core fitment for this model. That keeps the original sizing question straightforward for this sub-model.

Since the size itself does not change, attention can shift to the kind of 670-15 tire that best suits the car. A blackwall can give a plainer, more understated look, while narrow and wide whitewalls create a stronger mid-1950s presentation. Owners considering radial-equivalent alternatives should still confirm the actual wheel setup before changing construction.

For the 1955 Kaiser Manhattan, 670-15 is the primary bias-ply tire size. The available products in this fitment are bias-ply tires, which reflects the original construction style associated with this application.

Keeping a bias-ply tire usually makes the most sense when the goal is a traditional profile and period-style road feel. A move away from bias-ply changes more than the construction name on the sidewall, so wheel width, clearance, and the car's intended use deserve a close look before choosing a radial-equivalent size instead.

Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. Those represent an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial alternative.

Each of those sizes gives the 1955 Kaiser Manhattan owner a different way to approach radial construction, but none should be treated as automatic interchangeability. The recommended rim-width range for these equivalents is 5 to 7 inches, and it is smart to compare the tire choice against the car's actual wheels, steering clearance, and overall stance before making the switch.

Yes, 670R15 is available as a bias-look radial equivalent for the 1955 Kaiser Manhattan's original 670-15 size. It is intended for owners who want a radial construction while keeping a more traditional visual presentation than a modern metric sidewall usually provides.

That makes it especially relevant for a car that is driven regularly but still expected to look at home on a mid-1950s body. Even so, a bias-look radial is still a radial equivalent rather than the original bias-ply construction, so wheel width, tire dimensions, and body or steering clearance should be checked before making the change.

Start with the fact that 670-15 is the correct primary size, then narrow the choice by construction, sidewall appearance, and wheel compatibility. For the 1955 Kaiser Manhattan, the available tires are bias-ply, with product differences that include blackwall, narrow whitewall, and wide whitewall styles across several brands and series.

After appearance, compare the tire's rim-width specification and any stated load figure so the choice suits the car's actual wheel setup and intended use. A Manhattan that is being restored for period style may point toward one kind of sidewall, while a driver-quality car may be judged more by practical fit and overall presentation.

The 1955 Kaiser Manhattan's 670-15 tire options include blackwall, narrow whitewall, and wide whitewall styles. That gives the owner a broad range of visual treatments within the correct primary size, from a restrained look to a much stronger mid-1950s presentation.

Sidewall style can change the car's appearance almost as much as the wheel itself, so it is worth choosing with the whole vehicle in mind. A subtle whitewall may suit a driver or lightly restored car, while a wider whitewall can create a more formal, restoration-oriented look. The right choice depends on the exact character you want the Manhattan to project.

The 1955 Kaiser Manhattan's 670-15 tire options include Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA. Those brands appear across several bias-ply series, with both blackwall and whitewall presentations available.

Brand matters less as a ranking exercise than as part of the overall style and specification mix. Some owners begin with a preferred sidewall treatment, while others compare the series name, rim-width range, or load figure first. That approach is usually more useful than trying to choose by brand alone, especially on a collector-era car with appearance goals.

A period-style 1955 Kaiser Manhattan usually starts with the original 670-15 bias-ply sizing and then narrows the choice by sidewall treatment and brand presentation. Since this size is offered in blackwall, narrow whitewall, and wide whitewall styles, the visual effect can be tailored without leaving the proper primary fitment family.

The best appearance choice depends on how the specific car is being restored and how closely originality matters to the owner. A buyer aiming for a historically faithful presentation should compare the tire choice with marque references, period photos, or other vehicle-specific documentation rather than assuming every whitewall width or brand treatment is equally appropriate.

Tire construction influences both the look and the stance of a restored 1955 Kaiser Manhattan. Staying with a 670-15 bias-ply keeps the car in its original-style construction family, which generally preserves the visual character most enthusiasts expect from an independent American passenger car of this era.

A radial equivalent can change the way the tire presents on the car even if the wheel diameter remains the same. That does not make it the wrong choice, especially for road use, but it does mean appearance-minded buyers should weigh construction alongside sidewall style. On a restoration, the tire should support the car's visual story as much as its drivability.

Yes. A 1955 Kaiser Manhattan may still use the correct 670-15 tire size in theory, but aftermarket wheels, changed wheel widths, suspension work, ride-height changes, or body repairs can all affect how a tire actually sits and clears the car.

That matters even more when considering a radial-equivalent size, because the original fitment question then becomes a wheel-and-clearance question as well. Checking the actual rim diameter, measured wheel width, steering travel, and fender space before selecting a tire helps prevent surprises, especially on a collector car that may have been altered at some point in its life.

Before putting a 1955 Kaiser Manhattan back on the road, inspect the wheels, valve stems, and the overall condition of the suspension and steering components that influence tire behavior. It is also wise to verify that the tires are mounted in the correct size and that inflation is set appropriately for the specific tire being used.

A collector car can look ready for a drive while still hiding issues such as cracked rubber bushings, loose steering parts, or wheel damage from years of storage. Once the car is moving, recheck for air loss, rubbing, and any sign of uneven contact or vibration. Early inspection after installation can catch fitment problems before they become larger ones.

670-15 tires on a collector 1955 Kaiser Manhattan should be maintained with regular pressure checks, visual inspection, and careful storage habits. Look for sidewall cracking, cuts, bulges, uneven tread wear, or slow air loss, especially on a car that spends long periods parked between outings.

Collector vehicles often age their tires by time and storage conditions rather than by mileage alone. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the rubber, and moving the car periodically can help avoid long-term flat spotting. Any tire that shows age-related deterioration deserves closer evaluation before road use.
