Reo 6 Cyl. Tires

Reo 6 Cyl. fitments in the years listed here include 30X5.77 and 30X5 for 1926, then 550-17 and 6.00-17 for 1933. The 30X5 products shown use a 20-inch rim, while both 550-17 products use a 17-inch rim. The 30X5.77 size is an earlier antique-style listing that needs to be matched carefully to the wheel and vehicle specification.

That means the correct tire cannot be chosen by make and model alone. Start with the year, then verify the actual wheel diameter on the car, and finally compare the stamped or measured wheel to the size family used in that year. On early cars, the overall tire diameter and the wheel diameter are not the same number, so the wheel itself needs special attention.

A 30X5 tire on a Reo 6 Cyl. uses antique diameter-by-section sizing. The 30 refers to the tire's overall outside diameter in inches, and the 5 refers to the nominal section width. It does not mean the tire fits a 30-inch wheel, and the available 30X5 products here are built for 20-inch rims.

That distinction matters because many modern buyers naturally read the first number as wheel diameter. On an early Reo 6 Cyl., the safe approach is to read the size code and the rim specification together rather than treating them as the same thing. If the car has 20-inch wheels and belongs to the early year group, 30X5 is the style of fitment you should be comparing.

Reo 6 Cyl. listings here cover two different rim diameters. The early 1926 30X5 setup uses a 20-inch rim, while the later 1933 sizes shown use 17-inch rims. That change is central to fitment because the wheel diameter is not interchangeable even when the vehicle name is the same.

Use the wheel as the final authority before selecting a tire. On the antique-style early size, the rim diameter is not stated in the 30X5 code itself, so the wheel must be checked directly. On the later 550-17 and 6.00-17 sizes, the 17-inch rim is part of the size code, which makes the later cars easier to sort once the year is known.

The available Reo 6 Cyl. products shown here are bias-ply tires, and the listed early and later size families are tube-type applications. That includes the antique 30X5 family and the later numeric 550-17 sizing. For a collector car of this age, tube fitment is part of using the tire correctly on the intended wheel type.

Inner tubes should be matched to the exact tire size and wheel condition rather than reused casually from an old assembly. During mounting, the wheel should also be inspected for rust, pitting, and bead-seat damage, because tube life depends heavily on wheel condition. That is especially important on prewar wheels that may have seen many decades of service or storage.

Begin with the model year because the Reo 6 Cyl. listings break into two separate eras: 1926 uses early 30X5-style sizing, while 1933 uses 550-17 or 6.00-17. After that, confirm the wheel diameter on the car, since the early setup is on 20-inch rims and the later setup is on 17-inch rims. On a 1933 car, the remaining choice is between the narrower 550-17 and the wider 6.00-17 fitment.

The most practical method is to compare the wheel, the existing tire markings if present, and any surviving service or restoration records. A car that has changed wheels at some point in its life can easily mislead the buyer if the year is treated as the only clue. Matching year, wheel diameter, and actual configuration will narrow the correct choice much faster than relying on appearance alone.

Reo 6 Cyl. products here include blackwall, wide whitewall, and double-whitewall sidewall styles. The 30X5 offerings include a blackwall Hartford tire and a wide whitewall Firestone option, while the 550-17 group includes blackwall, wide whitewall, and double-whitewall BFGoodrich versions. That gives buyers both restrained and more decorative period-style looks within the listed sizes.

Sidewall choice should follow the way the car is being restored and used. A blackwall usually suits a more utilitarian or understated presentation, while whitewall and double-whitewall treatments create a more formal prewar look. The key is to choose the sidewall style only after the correct size and rim diameter are settled, because appearance should not override the mechanical fitment.

The available Reo 6 Cyl. tires shown here come from Hartford, Firestone, and BFGoodrich. Hartford appears in the 30X5 size through the Hartford Aero series, Firestone appears in 30X5 through the Classic Bias Ply line, and BFGoodrich covers the 550-17 size through the Silvertown Classic Bias Ply series. All of the listed products are bias-ply tires suited to period-style collector use.

Brand choice on a car of this age is usually secondary to getting the year-correct size family and wheel diameter right. Once the fitment is settled, brand and sidewall style can help shape the final look of the restoration. Many owners also choose by visual character, since tread and sidewall presentation can change how an early Reo sits and reads at a glance.

Reo 6 Cyl. products here include Hartford Aero, Firestone Classic Bias Ply, and BFGoodrich Silvertown Classic Bias Ply series. Hartford Aero represents an early-style offering in the 30X5 size, while Firestone Classic Bias Ply and BFGoodrich Silvertown Classic Bias Ply are later collector reproductions within the listed size families. The practical difference in this set is less about radical construction changes and more about brand, visual style, and the specific size each series covers.

For most owners, the useful comparison is whether the series is offered in the exact size the car needs and whether the sidewall treatment suits the restoration. An early 1926 car and a 1933 car do not share the same tire family here, so the first filter is always fitment rather than series name. Once the size is correct, the series choice helps refine authenticity and appearance.

A Reo 6 Cyl. should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, ozone sources, and petroleum contamination. Tire pressures should be checked before storage and maintained during long idle periods so the casing is not left underinflated. On a prewar car, that routine matters because older-style bias-ply tires can flat-spot and age visibly when neglected.

If the car will sit for an extended period, roll it occasionally or use stands appropriately so one section of the tread is not carrying load month after month. Clean the tires gently and avoid dressings that leave a heavy gloss or chemical residue. Good storage habits do more to preserve a seldom-driven collector tire than mileage alone.

Tires on a Reo 6 Cyl. should be inspected before each drive and more thoroughly at regular intervals even if the car sees very little mileage. On a vehicle from the 1920s or 1930s, cracks, sidewall stiffness, tread separation, tube problems, and wheel-condition issues can appear long before the tread is worn out. Collector use does not reduce the need for inspection; it changes the type of wear and aging you need to watch for.

A practical inspection includes air pressure, sidewall condition, valve stems, tread surface, and the way the tire is seated on the wheel. Any vibration, pull, or sudden change in steering feel after the car has been sitting deserves immediate attention. Period vehicles benefit from having both the tires and the wheels looked over by a shop familiar with vintage tube-type assemblies.

A Reo 6 Cyl. tire should be replaced when age, cracking, hardening, distortion, persistent air loss, or casing damage appears, even if the tread still looks presentable. Collector tires often age out before they wear out, and that is especially true on low-mileage prewar cars that spend long periods parked. The visual condition of the tread alone is never a full measure of serviceability.

Replacement decisions should be made conservatively because an early car places a high value on predictable behavior at modest speeds. If a tire has an uncertain history, has been stored poorly, or shows any structural concern, retire it from road use and have the assembly reviewed by a specialist. Aged tires can still look acceptable while no longer being trustworthy in motion.

The Reo 6 Cyl. listings here show more than one period-appropriate size family rather than a single universal original tire. The early 1926 car uses antique-style 30X5 or 30X5.77 sizing, while the 1933 car uses 550-17 or 6.00-17 sizing. That tells you the original fitment changed over time as the model moved from taller early tires to later 17-inch applications.

To identify what belongs on a specific Reo 6 Cyl., match the year first and then confirm the car's actual wheel and restoration goal. Factory literature, surviving wheel markings, and marque expertise are the best guides when a car has been altered over the decades. The tire should support the car's period, stance, and wheel hardware rather than simply filling the fender opening.

Correct tire fitment absolutely affects how a Reo 6 Cyl. is judged, presented, and valued within the collector world. Size, sidewall treatment, and overall proportion change the stance of the car and can quickly make a restoration look either properly sorted or obviously off-period. On prewar cars, judges and knowledgeable enthusiasts tend to notice tire profile and wheel relationship immediately.

That does not mean every owner needs the same presentation, but it does mean the tire choice should fit the restoration standard you are aiming for. A touring driver may prioritize a tasteful period look, while a judged restoration may need a very specific visual treatment. Marque clubs and established restorers are useful references when appearance accuracy matters as much as mechanical fit.

Reo 6 Cyl. products here include blackwall, wide whitewall, and double-whitewall styles, and any of those can suit a prewar restoration depending on the presentation being pursued. Blackwalls create a more restrained and utilitarian appearance, while whitewall treatments can suit a more formal or dressed-up interpretation. The right answer depends on the specific year and the overall restoration character rather than on a single rule for every Reo 6 Cyl.

Choose the sidewall style after the size family is settled so the visual choice does not lead you into the wrong fitment. Period photographs, surviving unrestored cars, and marque references can help fine-tune that decision. The best-looking Reo 6 Cyl. restorations usually get both the proportions and the sidewall presentation working together.

A properly fitted modern collector-production bias-ply tire can be suitable for cautious public-road use on a Reo 6 Cyl., provided the tire size, wheel diameter, tube setup, and vehicle condition are all correct. Safety on a car of this era depends on the entire system, including brakes, steering, wheels, and suspension, not on the tire alone. The car should be driven with the limits of 1920s and 1930s design firmly in mind.

That means moderate speeds, generous following distance, and close attention to road surface changes. Before any real road use, have the wheel assemblies mounted and inspected by someone familiar with vintage tube-type tires. The right tire helps, but a prewar car still requires a deliberate driving style and sound mechanical condition to be used responsibly.

Before driving a Reo 6 Cyl., check tire pressure, visible sidewall condition, valve stems, wheel security, and any sign that a tube-type assembly has shifted or is losing air. Also look for cracking, bulges, or uneven seating at the bead area. Because the listed Reo 6 Cyl. applications are bias-ply and period-style, small issues that might be ignored on a modern daily driver deserve attention here.

A short, slow test roll after any tire work is wise before heading onto open roads. Pay attention to vibration, steering pull, brake feel, and how the car tracks, since those early warning signs often show up before a visible problem becomes serious. If anything feels different than usual, stop and inspect rather than trying to drive through it.

A Reo 6 Cyl. should be driven at modest, conservative speeds that suit prewar chassis design and bias-ply tire behavior. Even with newly made collector tires, the car is still an early machine with older steering, braking, and suspension characteristics. Tire capability should never be treated as permission to drive the car like a modern automobile.

The practical standard is to keep speed well within the comfort zone of the car, the road, and the driver, especially on crowned pavement, grooves, and uneven surfaces. Short pleasure drives, local events, and measured touring are much more in character than sustained high-speed use. If the car feels busy, wanders, or reacts strongly to road irregularities, reduce speed immediately.
