By 1965, Singer occupied a distinctive corner of the British small-car market, offering tidy, badge-engineered Rootes products with a more upscale flavor than many economy cars of the period. The Chamois, Gazelle, and Vogue gave buyers three very different personalities under one make, from compact city transport to more traditional small saloons. Tire choice across 1965 Singer models varies by model rather than by a single make-wide size, with the Chamois using 12-inch options and the Gazelle and Vogue sharing two 13-inch bias-ply sizes. Before choosing a tire for a 1965 Singer, the first step is confirming the exact model, then deciding whether originality or driving character matters most.
Which Tire Size Is Right for Your 1965 Singer
Four tire sizes apply across the 1965 Singer range, and they are not shared by every model. The main decision starts with confirming whether you have a Chamois or a Gazelle/Vogue, since those cars use different rim diameters, and then choosing between bias-ply and radial construction where both are available. Understanding that split before choosing a product saves time and helps match the tire to the right Singer model.
Year(s): 1965|Fit(s): Chamois|Construction: Radial|Rim: 12 in
145R12 is a radial size with a 145 millimeter nominal section width and a 12-inch rim diameter, with the unstated profile conventionally treated as an 80-series metric radial. This size is specific to the Singer Chamois and is available from Michelin in a blackwall tubeless design with an S speed rating, which carries a 112 mph ceiling. It suits Chamois owners who want a more modern radial construction while staying within the correct 12-inch fitment family.
Year(s): 1965|Fit(s): Chamois|Construction: Bias Ply|Rim: 12-in rim
5.50-12 is a numeric bias-ply size in which 5.50 denotes the nominal section width and 12 denotes the rim diameter. This size is specific to the Singer Chamois and represents the period bias-ply fitment route for that model's 12-inch wheels. It is the more era-correct choice for a traditional small British-car restoration where preserving original driving character matters more than moving to radial construction.
Year(s): 1965|Fit(s): Gazelle, Vogue|Construction: Bias Ply|Rim: 13 in
600-13 is a numeric bias-ply size, with 6.00 indicating nominal section width and 13 indicating rim diameter. This size is specific to the Singer Gazelle and Singer Vogue, and it is available from BFGoodrich with both narrow whitewall and wide whitewall sidewall styles; load capacity is 1,010 pounds at 32 psi. It is a strong fit for owners who want a traditional 13-inch bias-ply look on the larger Singer saloon models, especially when whitewall appearance is part of the car's presentation.
Year(s): 1965|Fit(s): Gazelle, Vogue|Construction: Bias Ply|Rim: 13 in
650-13 is a numeric bias-ply size, with 6.50 indicating nominal section width and 13 indicating rim diameter. This size is specific to the Singer Gazelle and Singer Vogue, and it is available from Coker Classic and US Royal in both narrow whitewall and wide whitewall styles; load capacity is 1,150 pounds at 32 psi. It appeals to Gazelle and Vogue owners who want a fuller period look within the proper 13-inch bias-ply category.
Three Singer models are covered for 1965. They do not all share the same tire sizes, so identifying whether you have a Chamois, Gazelle, or Vogue matters before narrowing down the correct fitment family. Select a model below for model-specific tire history, size guidance, and applicable products.
1965 Singer Chamois
The Singer Chamois was the more upscale companion to the Hillman Imp, blending compact rear-engine packaging with a slightly more polished Singer presentation. Its tires mount on 12-inch rims, and the choice here centers on either a period-style bias-ply size or a radial alternative in the same small-car fitment class.
The Singer Gazelle carried the familiar small British saloon formula with slightly more trim and formality than its Hillman relatives, making it one of Singer's best-known postwar models. Its tires mount on 13-inch rims, with both available sizes remaining within the traditional bias-ply family for a distinctly mid-1960s look and feel.
The Singer Vogue was the Singer-badged version of the Rootes small saloon with extra trim and a slightly more premium identity than mainstream stablemates. It also uses 13-inch rims, and both applicable tire sizes stay within the era-correct bias-ply category rather than introducing a radial-versus-bias decision.
Seven products are available across three tire sizes for 1965 Singer vehicles. 145R12 has one Michelin radial in blackwall, 600-13 has two BFGoodrich bias-ply options in narrow and wide whitewall, and 650-13 has four Coker Classic and US Royal bias-ply options in narrow and wide whitewall. Confirm your model first, then your construction and sidewall preference.
These FAQs sort out the model split between Chamois and the larger Gazelle and Vogue, explain the difference between 12-inch radial and bias-ply choices, and cover whitewall selection, setup, storage, and road-use considerations for a mid-1960s Singer.
Size Basics & Fitment
What tire sizes fit 1965 Singer vehicles?
1965 Singer vehicles use four sizes across three models. The Singer Chamois uses either 145R12 radial or 5.50-12 bias-ply tires on 12-inch rims. The Singer Gazelle and Singer Vogue use 600-13 or 650-13 bias-ply tires on 13-inch rims. Rim width guidance also differs by size where it is established: 145R12 fits a 4.5-inch rim, 600-13 fits 4.00 to 4.50-inch rims, and 650-13 fits 4.50 to 5.00-inch rims.
That means year and make alone are not enough to choose correctly. A Chamois owner should stay within the 12-inch family, while Gazelle and Vogue owners should remain in the 13-inch family and then decide which of the two bias-ply sizes best suits the car's intended look and setup. Checking the actual wheel before ordering is especially important on restored British cars, where wheel swaps over the years are common.
What does 145R12 mean on a 1965 Singer tire?
On a 1965 Singer, 145R12 is a metric radial size used on the Chamois. The 145 refers to a nominal section width of 145 millimeters, the R identifies radial construction, and the 12 is the wheel diameter in inches. In this style of older metric sizing, the profile is conventionally treated as an 80-series radial unless another aspect ratio is stated. Michelin offers this size as a tubeless blackwall with a 72S service description, and S corresponds to a 112 mph speed ceiling.
For a Chamois owner, that code matters because it points to a more modern tire architecture than the car's bias-ply alternative. It does not mean the tire belongs on every 1965 Singer model, since the Gazelle and Vogue use 13-inch sizes instead. If your goal is easier road use and you already have correct 12-inch wheels, 145R12 is the radial path to investigate.
Do all 1965 Singer models use the same tire size?
No, 1965 Singer models do not all use the same tire size. The Chamois stands apart with 12-inch fitments, using either 145R12 radial or 5.50-12 bias-ply. The Gazelle and Vogue share the same two 13-inch bias-ply sizes, 600-13 and 650-13. That split reflects the fact that Singer sold a very small rear-engine car alongside more conventional small saloons in the same model year.
The practical takeaway is simple: identify the model before worrying about sidewall style, brand, or construction. A Chamois tire search should begin with 12-inch options, while a Gazelle or Vogue search should begin with 13-inch options. Once the model is confirmed, you can narrow the decision to a radial-versus-bias choice for the Chamois or to whitewall style and section width for the Gazelle and Vogue.
Buying the Right Tire
Should I choose the 145R12 or the 5.50-12 for my 1965 Singer?
That choice applies only to the 1965 Singer Chamois, since the Gazelle and Vogue use 13-inch bias-ply sizes instead. The 145R12 is a radial with a 145 millimeter section width on a 12-inch rim, while the 5.50-12 is a traditional numeric bias-ply size on the same rim diameter. The radial route brings a more modern tire construction, while the 5.50-12 keeps the Chamois in a more historically familiar bias-ply category.
Most buyers decide between those two by asking what kind of ownership experience they want from the car. A preservation-minded Chamois often leans toward the bias-ply size, while a driver-focused car may lean toward the radial alternative. Either way, verify that the wheels are true 12-inch Chamois wheels and that the tire you choose matches the car's intended use rather than assuming every small British size is interchangeable.
What sidewall styles are available for 1965 Singer tires?
1965 Singer tire sidewall options vary by size. The Chamois radial option, 145R12, comes as a blackwall. The 600-13 size for the Gazelle and Vogue is available in narrow whitewall and wide whitewall forms, while 650-13 is also available in both narrow and wide whitewall styles. Those choices suit the mid-1960s British saloon market well, especially on Gazelle and Vogue models where whitewalls can complement a more formal presentation.
Choosing among those sidewall styles is usually more about appearance and restoration character than basic fitment. A blackwall tends to look more understated and compact on a Chamois, while whitewalls can give a Gazelle or Vogue a more period-dressed look. If authenticity matters for judged events, compare your choice with period photos, market-specific literature, and marque-club guidance rather than treating every 1965 Singer as visually identical.
What brands make tires for 1965 Singer vehicles?
Four brands cover 1965 Singer applications across the available sizes. Michelin makes the 145R12 radial for the Singer Chamois. BFGoodrich covers 600-13 bias-ply fitments for the Gazelle and Vogue, while Coker Classic and US Royal both offer 650-13 bias-ply choices for those same 13-inch Singer saloon models. Brand selection therefore depends first on model and size, not simply on make and year.
That brand spread gives Singer owners a few different ways to match the car's character. A Chamois owner looking at 145R12 is really choosing the radial route, while Gazelle and Vogue owners can compare whitewall presentations within 13-inch bias-ply offerings. Start with the correct size family, then compare sidewall look, construction type, and any load or rim-width differences before settling on a specific product.
Fitting & Setup
What rim width do 1965 Singer tires require?
Rim width requirements for 1965 Singer tires depend on the size and model. The 145R12 used on the Singer Chamois fits a 4.5-inch rim. The 600-13 used on Singer Gazelle and Singer Vogue applications fits 4.00 to 4.50-inch rims, while the 650-13 fits 4.50 to 5.00-inch rims. All three of those sizes are tied to specific wheel diameters as well, so width and diameter need to be checked together.
That makes wheel verification an important step before mounting tires on a restored Singer. A Gazelle or Vogue wheel that suits a 600-13 may not be ideal for a 650-13, even though both are 13-inch sizes. Measure the wheel or confirm its specification before changing section width, especially if the car has had cosmetic wheel changes or substitutions during earlier restoration work.
Do 1965 Singer tires require inner tubes?
Tube requirements vary by size on 1965 Singer applications. The Michelin 145R12 for the Singer Chamois is a TL tire, meaning tubeless. The 600-13 and 650-13 bias-ply products do not carry TL markings in their size designations, so they should be treated as tube-type fitments unless the specific wheel and tire manufacturer guidance clearly supports another arrangement. Construction and wheel design matter as much as the size code itself on cars of this era.
For a buyer, the safest approach is to confirm the tire's sidewall marking and the wheel's intended tube or tubeless service before final setup. British collector cars often have original wheels, refurbished wheels, or replacement wheels from related models, and each can change the right answer. Tubes, valve stems, and wheel condition should all be considered together rather than as separate decisions.
Maintenance, Storage & Longevity
How should I store a 1965 Singer when the tires are fitted?
A 1965 Singer should be stored in a cool, dry space away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment that can age rubber. Keep the tires clean, maintain appropriate inflation, and move the car periodically so the casing does not sit on one contact patch for months at a time. Bias-ply tires such as 5.50-12, 600-13, and 650-13 are especially prone to temporary flat-spotting during long static storage compared with the Chamois' radial 145R12 option.
Long-term storage works best when the tires are treated as part of the car's preservation plan rather than an afterthought. If the Singer will be parked for an extended season, occasional rolling or properly supporting the car can help reduce stress on the carcass. Good storage habits preserve appearance as well as function, which matters on a small British classic where the tires are a visible part of the overall presentation.
How long do tires on a 1965 Singer typically last?
Tires on a 1965 Singer should be judged more by age and condition than by mileage. Collector-car tires often age out before they wear out, so a careful inspection around five to seven years is wise, and replacement becomes a serious consideration as they approach ten years from the DOT date code, even if tread depth still looks healthy. That principle applies to both the Chamois radial option and the Gazelle/Vogue bias-ply sizes.
A low-mileage Singer can still be riding on tires that are no longer suitable for regular road use. Sidewall cracking, hardening rubber, repeated pressure loss, vibration, or visible casing distortion are all stronger warning signs than odometer readings alone. If the car's service history is unclear, checking the tire age should be one of the first steps before planning tours, club drives, or sustained highway miles.
How often should tires on a 1965 Singer be inspected?
Tires on a 1965 Singer should be inspected before every drive and again before any longer outing. Look for sidewall cracking, uneven tread wear, cuts, bulges, embedded debris, and signs that the tire is not holding pressure consistently. On tube-type applications such as the period bias-ply sizes, valve stem condition and any slow loss of air deserve extra attention because tube and stem issues can show up before external wear becomes obvious.
Frequent inspection matters because these cars are often driven intermittently rather than daily. A Singer that sat for several weeks in the garage can reveal age-related issues that were not obvious on the previous outing. Developing a quick routine around pressure, sidewalls, and general appearance is one of the simplest ways to avoid tire-related trouble and preserve the confidence to use the car more often.
Restoration & Authenticity
What tires were originally fitted to the 1965 Singer Chamois?
For a 1965 Singer Chamois, bias-ply construction is the historically familiar baseline for originality-minded restoration, and 5.50-12 represents that period style within the Chamois fitment family. The 145R12 radial is a later-style construction choice within the same 12-inch diameter group rather than the default originality path. As with many 1960s British cars, market differences, dealer practices, and running changes can influence what an individual car wore when new.
That means the most accurate answer for a particular Chamois comes from comparing the car's surviving wheels and literature with marque-club knowledge. If the goal is judging or a highly faithful restoration, confirm not only size but also construction and sidewall appearance. If the goal is sympathetic road use, the correct 12-inch fitment family still matters, even if the final decision leans toward a radial rather than a bias-ply tire.
Does correct tire fitment matter for showing a 1965 Singer?
Correct tire fitment matters on a 1965 Singer because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall style immediately. A Chamois wearing a modern-looking radial can present differently from one on a period-style bias-ply, and a Gazelle or Vogue can look noticeably different depending on whether it wears narrow whitewalls or wide whitewalls. Even when the tire physically fits, the visual effect can change the car's authenticity in a show setting.
What counts as correct depends on the event and the standard being applied. Some shows emphasize broad period correctness, while others reward very exact market- and trim-specific details. If you plan to show the car seriously, use period photos, factory literature, and Singer or Rootes specialists to decide whether blackwall, narrow whitewall, wide whitewall, bias-ply construction, or radial construction best supports your restoration goals.
What is the difference between 600-13 and 650-13 for the 1965 Singer?
Both 600-13 and 650-13 are 13-inch bias-ply sizes used on the 1965 Singer Gazelle and 1965 Singer Vogue, but they are not identical. The 600-13 fits 4.00 to 4.50-inch rims and carries a maximum load rating of 1,010 pounds at 32 psi, while the 650-13 fits 4.50 to 5.00-inch rims and carries 1,150 pounds at 32 psi. Sidewall choices are broader in 650-13, with Coker Classic and US Royal offering narrow and wide whitewall versions.
For restoration work, the choice often comes down to wheel width, desired stance, and the appearance you want the car to project. A Gazelle or Vogue already sitting on narrower wheels may naturally point toward 600-13, while a wider correct wheel may open the door to 650-13. Confirm the actual rim before changing widths, because staying within the correct wheel range is as important as choosing a size that looks right.
Safety & Road Use
Are 1965 Singer tires safe for highway driving?
1965 Singer tires can be suitable for highway use when they are the correct size, in sound condition, and used within their construction limits. The 145R12 Michelin radial for the Singer Chamois carries an S speed rating, which corresponds to 112 mph. The 600-13 and 650-13 bias-ply sizes for the Gazelle and Vogue do not carry a speed letter here, so they should be treated with the more conservative expectations appropriate to traditional bias-ply collector tires.
On a mid-1960s Singer, overall roadworthiness usually depends as much on brakes, steering, suspension, and general mechanical condition as on the tire alone. A healthy tire does not override the limitations of an older British chassis. For regular road use, match the tire to the way the car will actually be driven, and avoid assuming that a period-style bias-ply should be pushed like a modern performance radial.
What inflation pressure should I use for 1965 Singer tires?
Inflation pressure for 1965 Singer tires should begin with the car's original handbook or factory recommendation for the exact model, then be checked against the tire manufacturer's own rated limits. Two of the 13-inch bias-ply sizes carry clear load-and-pressure figures: 600-13 is rated at 1,010 pounds at 32 psi, and 650-13 is rated at 1,150 pounds at 32 psi. Those figures are tire capacities, not universal instructions to use the same pressure in every Singer application.
The important point is not to transfer one pressure number casually from one size or model to another. Chamois, Gazelle, and Vogue applications are different, and front-to-rear pressures may also differ on the car itself. Use the vehicle maker's guidance for normal service, stay within the tire's own limits, and recheck pressure when the tires are cold, especially after the car has been parked for a while.
What should I check before taking a 1965 Singer on a longer drive?
Before a longer drive in a 1965 Singer, inspect each tire for cracking, cuts, bulges, uneven wear, and signs of age-related hardening. Confirm cold pressure, look closely at the valve stems, and make sure the spare is usable and inflated. On tube-type bias-ply applications, any slow leak or stem deterioration deserves immediate attention because the car may sit long enough between drives for small issues to grow unnoticed.
A proper pre-drive check should also include the broader basics that matter on an older British car: brakes, fluid levels, wheel fasteners, steering feel, and suspension condition. Tires are only one part of the equation, but they are the part that touches the road. Spending a few minutes on inspection before a tour or club run can prevent the kind of avoidable roadside problem that undermines confidence in an otherwise enjoyable Singer.
