1958 Vauxhall PAS & PAD Tires

The 1958 Vauxhall PAS & PAD uses two tire sizes: 640-13 in bias-ply construction and 175R13 in radial construction. Both sizes are associated with a 13-inch rim, so the main difference is not wheel diameter, but the tire type and sizing system you want to use on the car.

Choosing between them starts with the car's current wheel setup and your goals for use and appearance. A 640-13 keeps the period-style numeric bias-ply format, while 175R13 follows a Euro-metric radial format. Any car that has had wheel changes, suspension work, or other modifications should have its actual setup checked before a final tire decision is made.

The tire fitments for a 1958 Vauxhall PAS & PAD are built around a 13-inch rim diameter. Both the 640-13 bias-ply size and the 175R13 radial size use that same wheel diameter, which simplifies the basic rim-diameter question even though the tire constructions differ.

Rim diameter is only one part of the fitment picture, so it helps to confirm wheel width as well before moving from one tire type to another. That becomes especially important if the car has replacement wheels rather than original-style rims. A 13-inch wheel can still vary in width and shape enough to affect how a bias-ply or radial tire sits and clears.

Yes. The 1958 Vauxhall PAS & PAD Base uses the same two tire-size paths found on this fitment: 640-13 in bias-ply construction and 175R13 in radial construction. The choice is consistent at the sub-model level, so there is no separate Base-only size to sort out first.

That means the real decision is about construction and presentation rather than trim-level differences. Owners aiming for a more traditional look may focus on the 640-13, while owners considering a radial-format option can evaluate 175R13. Checking the actual wheels on the car still matters, especially on a collector vehicle that may have been changed over time.

640-13 is a bias-ply tire size for the 1958 Vauxhall PAS & PAD. It uses the vintage numeric sizing system and represents the traditional tire construction associated with this fitment, while 175R13 is the radial-format alternative on the same 13-inch rim diameter.

That distinction matters because a bias-ply choice affects both the car's visual presentation and the overall direction of the tire setup. Owners preserving a period-style look often begin with 640-13, while anyone considering a move to radial construction should compare wheel width, tire dimensions, and clearance carefully rather than assuming the change is automatic just because rim diameter stays the same.

Radial equivalents for 640-13 include 175R13, P175/75R13, P185/70R13, and 650R13. Those choices cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial alternative that keeps a more traditional visual theme than a standard modern radial.

Each of those sizes should be treated as an alternative to evaluate, not as an automatic swap. The associated rim-width range is 4-6 inches, and that should be checked along with the actual wheel, available fender room, and suspension clearance. On a car that has seen wheel or ride-height changes, that step is especially important before converting away from 640-13.

Start by confirming the wheel diameter and width, then compare the radial size you are considering with the car's available space around the fenders, steering, and suspension. For a 1958 Vauxhall PAS & PAD, the common radial alternatives tied to 640-13 stay on a 13-inch rim, but they still need to be evaluated as complete fitments.

Construction changes can also alter the overall character of the car, so the decision is about more than just size code. A restoration-minded owner may prefer the traditional look of 640-13, while a driver may want to explore 175R13, P175/75R13, P185/70R13, or 650R13. Wheel condition and tire clearance should both be checked before the conversion is finalized.

A 640-13 choice for a 1958 Vauxhall PAS & PAD starts with confirming that you want to stay with the bias-ply construction and vintage numeric size used by this fitment. From there, the important comparisons are sidewall appearance, rim-width compatibility, load capacity, and how closely the tire suits the car's intended use and presentation.

The available 640-13 product includes a BFGoodrich Silvertown Classic Bias Ply with a 2.25-inch wide whitewall, which makes appearance a major part of the decision. Buyers using the car for shows, period-style presentation, or traditional restoration themes may prioritize that look differently than owners focused mainly on driving use. Wheel condition and actual width should still be confirmed before installation.

The visible sidewall style available in the 640-13 fitment for a 1958 Vauxhall PAS & PAD is a wide whitewall. In practical terms, that gives the car a strong period-style look and makes sidewall presentation a meaningful part of the buying decision rather than just a minor cosmetic detail.

Sidewall choice matters most when the car is being preserved or restored with a traditional visual theme. A wide whitewall can change the whole stance and character of a late-1950s saloon, even when the tire size stays the same. Buyers should separate appearance goals from construction goals, since a whitewall bias-ply decision is not the same thing as choosing a radial-format alternative.

BFGoodrich is represented in the available tire selection for the 1958 Vauxhall PAS & PAD, specifically in the 640-13 bias-ply size. That product sits in the Silvertown Classic Bias Ply line and combines the period-size format with a wide whitewall presentation aimed at traditional vintage-car appearance.

Brand is only one part of the decision, so it helps to compare the full tire character rather than shopping by name alone. On this fitment, the bigger questions are whether you want the 640-13 bias-ply route or a radial-format size such as 175R13. Once that is settled, wheel width, visual style, and intended road use become the next checkpoints.

For a period-style 1958 Vauxhall PAS & PAD, the 640-13 bias-ply size is the natural starting point because it keeps the vintage numeric sizing format and traditional construction associated with this fitment. It also supports a more authentic late-1950s visual character than a modern-looking radial size code tends to convey.

That does not automatically make every 640-13 presentation historically identical, so appearance details still matter. The available wide whitewall option creates a distinctly restoration-oriented look, but exact originality should be checked against marque references, photos, or other vehicle-specific documentation when that level of accuracy is important. Construction, stance, and sidewall treatment all shape the final result.

Tire construction changes more than the way the size is written on the sidewall. On a restored 1958 Vauxhall PAS & PAD, a 640-13 bias-ply tire gives the car a more traditional visual tone, while a 175R13 or other radial-format equivalent introduces a later sizing style that can look less period-specific.

That difference becomes even more noticeable when sidewall styling enters the picture. A wide whitewall bias-ply combination can strongly reinforce a late-1950s presentation, whereas a radial selection may appeal more to an owner who values road use over a strictly vintage look. The right answer depends on whether the restoration priority is authenticity of appearance, driving practicality, or a balance of both.

Yes. Modifications can change tire fitment on a 1958 Vauxhall PAS & PAD even when the tire size itself looks correct on paper. Aftermarket wheels, changes in wheel width, altered offset, lowered suspension, replacement springs, or body work can all affect how either a 640-13 bias-ply tire or a 175R13 radial sits on the car.

That is why the actual vehicle should be inspected before settling on a tire choice, especially when considering one of the radial equivalents tied to 640-13. Steering clearance, fender room, and suspension travel deserve attention on any modified car. A collector vehicle that has changed hands several times may have fitment differences that are not obvious at first glance.

Before road use, inspect tire pressure, valve stems, wheel condition, lug security, and visible clearance around the fenders and suspension. A 1958 Vauxhall PAS & PAD should also be checked for any rubbing at full steering lock, since even a correct-size tire needs to work with the car's actual wheel and suspension condition.

Collector cars benefit from a broader inspection before the first real drive. Look for aged brake components, loose steering parts, worn shocks, and wheel issues that could affect how the new tires behave on the road. A short, low-speed test drive followed by another visual check is a sensible way to confirm that the tire and wheel package is settling correctly.

Tires on a collector 1958 Vauxhall PAS & PAD should be checked regularly for pressure loss, sidewall cracking, tread wear, bulges, cuts, and signs of long-term aging. Cars that spend much of their time parked can develop tire issues quietly, so condition matters just as much as tread depth on a low-mileage vintage vehicle.

Storage habits have a major effect on tire life. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve both bias-ply and radial tires. It also helps to move the car periodically, maintain correct inflation, and inspect the tires before every extended drive rather than assuming occasional-use collector tires remain road-ready on appearance alone.
