1929 Peerless 125 Series Tires

The 1929 Peerless 125 Series is associated with two primary bias-ply tire sizes: 31X6.20 and 650-19. Those are not modern radial substitutions; they are the actual vintage-style fitments tied to this vehicle. The covered 1929 Peerless 125 Series 8 Cyl. can appear with either of those sizes.

That means the right choice starts with the car in front of you, not a broad assumption about the model name alone. Check the existing wheel and tire setup carefully, confirm that the wheel is a 19-inch rim where applicable, and compare the size already on the car before selecting a replacement tire.

The 1929 Peerless 125 Series uses a 19-inch rim with its primary tire fitment. The 650-19 size states that rim diameter directly, and the vehicle's covered tire applications are tied to 19-inch wheel use overall. That rim diameter is central to choosing a correct vintage-style replacement.

Rim diameter should be confirmed on the actual car before ordering tires, especially on an older vehicle that may have had wheel changes over its lifetime. Wheel width matters too, since some 650-19 products are associated with specific rim-width ranges such as 3.25 to 3.50 inches or 3.25 to 4.25 inches.

31X6.20 is an antique diameter-by-section tire size. In that format, 31 refers to the tire's approximate overall diameter in inches, while 6.20 refers to the section width. It is a bias-ply fitment and reflects the tall, early tire sizing conventions used on many late-1920s luxury automobiles.

That older format can look unfamiliar next to later numeric sizes such as 650-19, so it is worth reading the sidewall carefully before buying replacements. On a Peerless, understanding the format helps avoid mixing sizing systems and keeps the focus on confirming the wheel, the current setup, and the traditional appearance you want to preserve.

Start with the basics: confirm that 650-19 is the actual size used on the car, that the wheel is a 19-inch rim, and that the tire remains bias-ply to match this vintage application. Then compare the available product details, including brand, tire series, sidewall style, and any stated rim-width compatibility.

For many Peerless owners, the real decision comes down to appearance and use. A blackwall gives a restrained period look, while a wide whitewall creates a stronger restoration-style statement. Where specifications are shown, details such as product weight or a load figure like 1430@36 psi can also help separate one 650-19 option from another.

The available 650-19 tire choices for a 1929 Peerless 125 Series include both blackwall and wide whitewall sidewall styles. Those two looks create very different visual results even when the tire size stays the same. Firestone, Lester, and Excelsior offerings cover the traditional blackwall side, while wide whitewall options are also available in this size.

Sidewall style is largely an appearance decision, but it should still be made after the size and wheel setup are confirmed. Buyers aiming for a subdued touring-car look often lean toward blackwall, while a more formal restoration presentation may point toward wide whitewall. Historical photos, marque references, and the car's intended finish can help settle the choice.

For the 650-19 fitment used on the 1929 Peerless 125 Series, available brands include Firestone, Lester, and Excelsior. Those options appear across several vintage-style lines, including Firestone Classic Bias Ply, Firestone Balloon, Lester Classic Bias Ply, and Excelsior's Comp H series. All of them stay within the traditional bias-ply character of the car.

Brand choice is only one part of the decision. It helps to compare the series name, sidewall treatment, wheel-width range where stated, and overall presentation you want on the vehicle. A Peerless restored for formal display may call for a different visual approach than one intended for regular touring on period-style bias-ply tires.

A period-style 1929 Peerless 125 Series starts with the correct primary size already associated with the car, either 31X6.20 or 650-19, and with bias-ply construction rather than a modern-looking substitute. That sizing and construction combination preserves the tall-profile stance and visual character expected from a late-1920s luxury automobile.

Once the size is confirmed, appearance becomes the deciding factor. A blackwall keeps the presentation understated, while a wide whitewall creates a more formal restoration-oriented look. For owners pursuing exact historical authenticity, marque-club references, period photos, and vehicle-specific documentation are the best way to narrow the final sidewall and series choice.

Correct tire fitment matters a great deal on a 1929 Peerless 125 Series because tire size has a strong effect on both appearance and stance. On a car from this era, an incorrect size can look noticeably out of place even before road behavior enters the conversation. Bias-ply construction is also part of that authentic visual profile.

Beyond appearance, proper fitment helps the tire work with the wheel dimensions and body clearances the car actually has. Since this Peerless can be associated with both 31X6.20 and 650-19, a careful check of the wheel and current setup is essential. That extra step helps avoid compromising the restoration's overall presentation.

Yes, modifications can affect tire fitment on a 1929 Peerless 125 Series. If the car has replacement wheels, altered wheel widths, suspension work, body repairs, or stance changes made over the years, those changes can influence which of the two primary tire sizes remains appropriate and how much clearance is available.

Older collector cars often carry decades of changes that are not obvious at first glance, so the safest approach is to inspect the actual wheel and tire combination on the car. Check rim diameter, wheel width, steering clearance, and fender space before selecting either 31X6.20 or 650-19 for continued road use.

Before driving a 1929 Peerless 125 Series on new tires, inspect the wheels for condition, verify that the tires match the wheel setup, and confirm that the beads are properly seated. It also makes sense to check valve hardware, inflation pressure, and general clearance around the fenders, steering components, and suspension at full lock.

A brief shakedown inspection after the first miles is just as important on a low-use collector car. Look for rubbing marks, uneven seating, air loss, or anything unusual in how the car tracks and steers. Vintage vehicles reward careful observation, especially when fresh bias-ply tires are being introduced to an older chassis.

650-19 tires on a collector 1929 Peerless 125 Series should be maintained with regular pressure checks, visual inspections, and careful storage habits. Keep an eye on tread condition, sidewall cracking, bulges, cuts, and any sign of air loss. On a car that sees limited use, age and storage conditions deserve as much attention as mileage.

Heat, direct sunlight, moisture, and ozone sources can all shorten tire life on vintage vehicles that spend long periods parked. Periodic movement helps avoid long-term flat spotting, and a pre-drive inspection is wise before every outing. That routine is especially important on a heavy pre-war automobile running tall bias-ply tires.
