1966 Vauxhall Victor & VX 4/90 Tires

The 1966 Vauxhall Victor & VX 4/90 uses two primary tire sizes: 155R13 in radial construction and 560-13 in bias-ply construction. Both sizes are tied to 13-inch rims, so the fitment question is less about wheel diameter and more about which construction and tire style best match the car.

Choosing between them starts with confirming the actual wheel width on the car. The radial and bias-ply options use different rim-width ranges, and that matters just as much as the size code itself. If the car has been modified with different wheels over the years, measure the rims before selecting a tire.

The 1966 Vauxhall Victor & VX 4/90 uses a 13-inch rim diameter with both of its primary tire sizes. That applies whether the car is running the 560-13 bias-ply fitment or the 155R13 radial fitment, so rim diameter remains consistent across the available tire choices.

The more important follow-up is rim width, since the radial and bias-ply offerings do not share the same width requirements. A 560-13 bias-ply may call for a narrower wheel than a 155R13 radial. Verifying both diameter and width helps prevent choosing a tire that matches the code but not the wheel.

560-13 is a vintage numeric bias-ply size. The 5.60 designation refers to nominal section width in inches, and the 13 indicates the wheel diameter in inches. On a 1966 Vauxhall Victor & VX 4/90, it represents the traditional bias-ply fitment and a more period-style tire construction.

That matters because a 560-13 is not interpreted the same way as a modern metric radial size. Buyers often compare it with radial equivalents such as 155R13 or P155-series options, but those are alternatives rather than automatic replacements. Wheel width, overall dimensions, and vehicle clearance should be checked before making a construction change.

560-13 is a bias-ply tire size on the 1966 Vauxhall Victor & VX 4/90. It uses the older numeric sizing system and is offered here in classic bias-ply form, including whitewall versions that suit a traditional mid-1960s presentation.

That makes it the right place to start for an owner who wants the car to keep a vintage visual character and a period-style construction. A switch away from 560-13 should not be treated as automatic just because the rim diameter stays at 13 inches. Wheel width and clearance still need to be confirmed.

Radial equivalents for 560-13 include 155R13 as the 80-series metric radial option, P155/75R13 as the P-metric 75-series radial option, and P155/70R13 as the P-metric 70-series radial option. These are alternative radial sizes associated with the original 560-13 bias-ply fitment.

Each equivalent uses a different sizing convention, so the decision is not simply radial versus bias-ply. The recommended rim-width range for the conversion is 4 to 5 inches, and that should be checked against the actual wheels on the car. Clearance around the fenders and steering should also be reviewed before changing sizes.

Either can be appropriate, because the 1966 Vauxhall Victor & VX 4/90 has both 560-13 bias-ply and 155R13 radial fitments within its 13-inch setup. The choice depends on whether the priority is a traditional period-style appearance or a radial construction more aligned with later tire technology.

A bias-ply selection keeps the car closer to an earlier visual and construction style, especially with whitewall options. A radial choice moves toward blackwall modernized fitment within the same rim diameter. The smartest approach is to match the tire to the wheel width already on the car and to the way the vehicle will actually be used.

Start with the correct construction and size for the car’s current wheel setup. The 1966 Vauxhall Victor & VX 4/90 uses either 560-13 bias-ply or 155R13 radial tires on 13-inch rims, so the key decision is whether the car is staying with a traditional bias-ply look or moving to a radial format.

After that, compare wheel-width compatibility, sidewall style, brand, and tire series. The available bias-ply options lean toward whitewall presentation, while the radial offerings are blackwall. Tire weight and load figures can also help narrow the choices, but only after the correct size and wheel match have been confirmed.

The available sidewall styles for the 1966 Vauxhall Victor & VX 4/90 include blackwall, narrow whitewall, and wide whitewall. Blackwall appears with the radial 155R13 options, while the 560-13 bias-ply choices include both narrow and wide whitewall presentations.

That split makes sidewall choice an important part of the overall direction of the car. A blackwall radial gives the Victor & VX 4/90 a cleaner, more understated look, while a whitewall bias-ply pushes it toward a stronger period-style presence. Appearance should still be balanced against construction preference and wheel-width compatibility.

Michelin, Dunlop, BFGoodrich, and Firestone all have applicable tire offerings for the 1966 Vauxhall Victor & VX 4/90. Michelin and Dunlop cover the radial 155R13 fitment, while BFGoodrich and Firestone appear in the 560-13 bias-ply range with restoration-oriented whitewall options.

Brand choice is best treated as part of a larger comparison rather than the first decision. Construction, sidewall style, tire series, and wheel-width suitability usually narrow the field more effectively. Once the correct size and type are established, the brand and series become a more meaningful way to choose among the remaining options.

For a period-style 1966 Vauxhall Victor & VX 4/90, the 560-13 bias-ply fitment is the strongest starting point. That size keeps the car in a traditional numeric tire format and is available in classic bias-ply series with whitewall treatments that suit a restoration-oriented presentation.

The exact look still depends on how the car is being finished. A narrow whitewall and a wide whitewall create noticeably different visual results, and period style does not always mean one universal appearance. If exact originality matters, compare the tire choice against marque references, period photos, or vehicle-specific historical documentation.

Tire construction changes the look of the 1966 Vauxhall Victor & VX 4/90 as much as it changes the fitment format. A 560-13 bias-ply carries a distinctly vintage presentation, especially in narrow whitewall or wide whitewall form, while the 155R13 radial options are blackwall and visually more modern.

That difference can influence how the whole car reads from the curb, particularly on a restoration where wheelcovers, ride height, and trim details are already being considered. Construction should not be chosen on appearance alone, though. Wheel-width compatibility and the intended road use of the car still deserve equal attention.

Yes, modifications can affect tire fitment on a 1966 Vauxhall Victor & VX 4/90 even when the tire size looks correct on paper. Changes such as aftermarket wheels, altered wheel width, suspension work, or body and fender adjustments can all influence how a 560-13 or 155R13 tire sits on the car.

That is especially important when considering a radial equivalent for the original bias-ply size. A different wheel width or offset can change clearance at the fender edge or during steering movement. Measuring the wheel and checking for available space around the tire is the safest way to avoid fitment surprises.

Before driving a 1966 Vauxhall Victor & VX 4/90 on new tires, inspect the wheels for correct diameter and width, check that the tires are seated properly, and confirm there is no interference at the fenders or suspension. Tire pressure, valve condition, and overall wheel condition also deserve attention before road use.

A collector car often has age-related issues beyond the tires themselves, so it also helps to look over suspension components, steering play, and brake condition. After the first short drive, recheck pressure and look for any signs of rubbing or unusual wear. Small problems are easier to correct before they become expensive ones.

Collector-car tires on a 1966 Vauxhall Victor & VX 4/90 should be inspected regularly for cracking, cuts, bulges, uneven tread wear, and gradual air loss. That applies whether the car is on 560-13 bias-ply tires or 155R13 radials, since both can age out long before they wear out on a lightly used vehicle.

Storage conditions matter just as much as mileage. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires between drives. It is also wise to check pressure before each outing and after longer periods of storage, since underinflation can cause avoidable stress on an older vehicle’s setup.
