1967 Singer Tire Fitment Guide

1967 Singer vehicles use four sizes across three models. The Singer Chamois uses 145R12 radial or 5.50-12 bias-ply sizes on 12-inch rims, while the Singer Gazelle and Singer Vogue use 600-13 or 650-13 bias-ply sizes on 13-inch rims. Rim width guidance is available for 145R12 at 4.5 inches, for 600-13 at 4.00 to 4.50 inches, and for 650-13 at 4.50 to 5.00 inches.

The practical takeaway is that year and make alone are not enough for a 1967 Singer. Start by confirming the model, then confirm whether your wheel is the 12-inch Chamois type or the 13-inch Gazelle or Vogue type. Once that is settled, the remaining choice becomes much simpler, especially if you are trying to balance restoration accuracy, sidewall appearance, and how you plan to drive the car.

On a 1967 Singer, 145R12 is a metric radial size. The 145 indicates a nominal section width of 145 millimeters, the R identifies radial construction, and the 12 is the wheel diameter in inches. In period-style metric sizing like this, the absent aspect ratio is conventionally treated as an 80-series profile rather than a modern low-profile design.

That decoding matters because 145R12 belongs only to the Singer Chamois and points you toward a different driving character than a bias-ply tire. It is also a 12-inch fitment, so it should never be confused with the 13-inch Gazelle and Vogue sizes. If your car wears later replacement wheels or has been altered over the years, verify the wheel diameter before choosing a tire.

No, 1967 Singer models do not all use the same tire size. The Chamois uses 12-inch fitments, with a choice between 145R12 radial and 5.50-12 bias-ply, while the Gazelle and Vogue share two 13-inch bias-ply sizes: 600-13 and 650-13. That split follows the different roles these cars played within the Singer lineup.

For a buyer, that means the badge on the boot or grille matters just as much as the model year. A Chamois owner may be deciding between construction types on the same rim diameter, while Gazelle and Vogue owners are comparing two bias-ply 13-inch sizes and often a whitewall treatment. Getting the model right first keeps you from chasing the wrong wheel diameter entirely.

That choice applies only to the 1967 Singer Chamois, since both sizes fit its 12-inch wheels. The 145R12 is a radial metric size, while the 5.50-12 is a traditional numeric bias-ply size. Radial and bias-ply construction differ in feel and presentation, even when they share the same wheel diameter.

Owners aiming for an original-looking Chamois often prefer the bias-ply route, especially if the car is being restored with an emphasis on period appearance. Owners who plan to use the car more regularly on modern roads may lean toward the radial option for a more contemporary driving feel. The right answer depends less on the wheel and more on how original you want the car to look and behave.

1967 Singer tire sidewall options vary by size. The 145R12 radial for the Singer Chamois comes as a blackwall, while 600-13 for the Singer Gazelle and Singer Vogue comes in narrow whitewall and wide whitewall versions. The 650-13 size also offers both narrow whitewall and wide whitewall treatments.

That gives Chamois owners a more understated radial appearance, while Gazelle and Vogue owners can tailor the look of their 13-inch bias-ply tires to suit the character of the car. Whitewall width can noticeably change the visual tone of a 1960s British saloon, so it is worth deciding early whether you want a subtler period look or a more prominent classic whitewall presence.

1967 Singer fitments are covered by several brands across the available sizes. Michelin covers the 145R12 radial, BFGoodrich covers the 600-13 bias-ply size, and Coker Classic plus US Royal cover the 650-13 bias-ply size. Those brand choices align with the split between a later-style small radial and traditional whitewall bias-ply offerings.

Brand matters most after you have narrowed the correct size and construction for your model. A Chamois owner looking at 145R12 is really choosing a radial path, while Gazelle and Vogue owners in 13-inch sizes can compare whitewall width and brand presentation within bias-ply construction. If authenticity is part of the goal, sidewall appearance can be just as important as the name on the casing.

Rim width guidance varies by size on 1967 Singer vehicles. The 145R12 radial uses a 4.5-inch rim, the 600-13 bias-ply fits 4.00 to 4.50-inch rims, and the 650-13 bias-ply fits 4.50 to 5.00-inch rims. Those ranges matter because two tires can share the same wheel diameter yet still favor different wheel widths.

This is especially important on Gazelle and Vogue models, where both 600-13 and 650-13 use 13-inch rims but do not share exactly the same rim-width range. Before mounting a replacement tire, measure the wheel or confirm its size through a trusted workshop. That step helps preserve the intended profile and keeps the tire from being squeezed onto a rim that is too narrow or spread across one that is too wide.

Tube use depends on the specific tire and wheel combination on a 1967 Singer. The 145R12 Michelin radial is marked TL, which means tubeless. The bias-ply 600-13 and 650-13 products do not carry a tube-type or tubeless marking in the size description here, so tube choice should be confirmed against the tire's sidewall marking and the construction of the wheel itself.

That distinction matters because many vintage wheels and tire designs were built around tube use even when modern buyers are more familiar with tubeless tires. If your Singer still has original-style wheels, inspect the rim condition and valve arrangement before mounting new tires. A tire specialist familiar with classic British wheels can help you match the tire and wheel correctly without assuming all 1967 Singer applications are the same.

Within each 1967 Singer model family, wheel diameter is the first checkpoint. The Chamois uses two 12-inch sizes, so both of its tire options share the same rim diameter. The Gazelle and Vogue use two 13-inch sizes, so those pairs also stay within a common rim diameter, but 600-13 and 650-13 call for different rim-width ranges.

That means original wheels can often remain part of the plan if the diameter is correct, but width still needs to be verified before you move between sizes. A Chamois owner comparing 145R12 and 5.50-12 should confirm the wheel suits the radial or bias-ply choice, while Gazelle and Vogue owners should make sure their 13-inch wheels fall within the proper range for 600-13 or 650-13.

A 1967 Singer stores best in a cool, dry, dark garage away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment. Keep the tires clean, maintain proper inflation, and move the car periodically so one section of the casing is not carrying the load for months at a time. Bias-ply tires tend to flat-spot more readily during long static storage than radials, so that matters especially for Gazelle and Vogue models and for Chamois cars running 5.50-12 bias-ply tires.

If the car will sit for a season, many collectors either roll it a short distance every few weeks or support it in a way that reduces sustained load on the tires. That extra care helps preserve the shape of the casing and the appearance of the sidewalls. It is a small step that can make a stored 1967 Singer feel much better when it returns to the road.

On a 1967 Singer, tire life should be judged more by age and condition than by mileage. Collector-car tires often cover modest annual distances, so sidewall aging, internal deterioration, and long periods of storage become more important than tread wear alone. A sensible routine is to begin evaluating them closely around the five- to seven-year mark and to treat around ten years as a serious replacement threshold, regardless of how much tread remains.

Check the date code on each tire and compare that age with how the car has been stored and used. A lightly driven Singer that lives indoors may still need replacement because rubber ages even when tread looks healthy. If the tires are older and the car is heading back into regular road use, replacing them before problems appear is usually the safer path than waiting for visible failure.

Tires on a 1967 Singer should be inspected before every drive and more thoroughly before any extended outing. Look for cracks in the sidewalls, bulges, cuts, irregular tread wear, and signs of air loss, then verify pressures with a dependable gauge. If your car uses a tube-type setup, include the valve stems and any signs of tube-related leakage in the inspection routine.

Frequent inspection matters because a collector car can sit for weeks and then suddenly be asked to run at road speed. Problems that develop quietly in storage often show up first in the sidewall or through pressure loss. A quick walkaround before each drive and a more detailed check before a weekend tour is one of the easiest ways to keep a 1967 Singer enjoyable and dependable.

For a 1967 Singer Chamois, the period-correct starting point is bias-ply construction, since bias-ply tires were still standard on many small cars of the era even as radials were becoming more common in Europe. The Chamois size set includes both 5.50-12 bias-ply and 145R12 radial fitments, which reflects that transitional period. No single original-equipment brand should be assumed without model-specific factory literature.

If you are restoring a Chamois for authenticity, begin with the original wheel diameter and then verify period sales material, owner literature, or a Singer and Rootes specialist before making the final call. Market differences and production timing can affect what was delivered new. That extra step is worthwhile because a concours-minded restoration may judge construction type and sidewall look as closely as the actual size.

Correct tire fitment absolutely matters when a 1967 Singer is prepared for judged events or a high-level restoration. Size, construction type, and sidewall appearance all shape whether the car looks appropriate for its year and market. A radial blackwall on a Chamois can present very differently from a bias-ply tire, while the wrong whitewall width on a Gazelle or Vogue can change the entire visual character of the car.

Show standards vary, so the right choice depends on whether the goal is general period character or strict originality. Club judging guides and marque specialists are the best final authority, especially for market-specific details. Even when two tire sizes fit the same rim diameter family, the more authentic choice for a show field is usually the one that best matches the car's original construction style and sidewall treatment.

For the 1967 Singer Gazelle and 1967 Singer Vogue, both 600-13 and 650-13 are bias-ply 13-inch sizes, but they are not identical. The 600-13 tires carry a maximum load rating of 1010 pounds at 32 psi and fit 4.00 to 4.50-inch rims, while the 650-13 tires carry 1150 pounds at 32 psi and fit 4.50 to 5.00-inch rims. Sidewall choices are similar, with narrow and wide whitewall versions available in both size families.

That means the decision is not just visual. Wheel width needs to match the tire, and the slightly larger size family changes the car's stance and overall presentation. For a restoration, it is wise to confirm which size best matches the car's original specification or the look you are trying to recreate, rather than choosing only by whitewall width or brand preference.

1967 Singer tires can be suitable for highway use when they are the correct size, in sound condition, and used within their design limits. The 145R12 radial carries an S speed rating, which corresponds to 112 mph. The bias-ply 600-13 and 650-13 products here do not show a speed letter, so their safe use depends on the tire's own construction limits, age, inflation, and the condition of the car itself.

In practice, a 1967 Singer will usually be limited more by vintage braking, suspension, and overall mechanical condition than by extreme tire speed capability during ordinary highway travel. The key is to treat the whole car as a period machine, not just the tires. Before longer road use, make sure the tires are fresh, properly inflated, and free from age-related cracking or deformation.

Inflation pressure on a 1967 Singer should follow the vehicle's original handbook recommendation for the specific model and tire size, with the tire maker's maximum load-and-pressure figure treated as a load reference rather than a blanket operating pressure. For the bias-ply sizes here, 600-13 is rated at 1010 pounds at 32 psi and 650-13 is rated at 1150 pounds at 32 psi. Those figures should not be transferred between sizes or treated as universal settings for every Singer.

The smartest approach is to confirm the car's factory pressure guidance first, then compare it with the tire's sidewall information and how the car is actually used. A lightly loaded collector car may not need to run at the tire's maximum rated pressure. Getting this right affects ride quality, steering feel, tread wear, and the long-term health of the casing.

Before a longer drive in a 1967 Singer, inspect every tire for sidewall cracking, punctures, cuts, bulges, uneven wear, and proper inflation. Check the spare as well, since many vintage cars still rely on an older spare that has been forgotten for years. If your tire and wheel setup uses tubes, include valve stems and any signs of slow leakage in the inspection.

Tires are only one part of the pre-drive routine on a 1960s British car, so it also makes sense to review brakes, cooling, steering, and fluid levels before setting out. The goal is not to overcomplicate a pleasant drive, but to reduce the chance that an age-related issue appears far from home. A careful inspection takes only a few minutes and suits the way a collector Singer is actually used.
