1966 Humber Super Snipe Tires

The 1966 Humber Super Snipe uses two recognized tire sizes: 185R15 in radial construction and 775-15 in bias-ply construction. Both are 15-inch fitments, so the car's tire choice is tied more to construction and existing wheel setup than to a change in rim diameter.

The practical next step is confirming what is already on the car. A Humber that has remained close to an earlier setup may still use 775-15 bias-ply tires, while another car may already be on 185R15 radials. Once that is clear, compare the wheel width, the available sidewall styles, and the overall appearance you want before making a final selection.

The tire sizes used on a 1966 Humber Super Snipe are built around a 15-inch rim diameter. Both the 185R15 radial size and the 775-15 bias-ply size share that same basic wheel diameter, which keeps the first fitment check simple.

Diameter is only part of the wheel question, though. Before choosing a tire, confirm the actual wheel on the car, especially if it has changed hands or seen restoration work over the years. Wheel width matters too, particularly when comparing radial and bias-ply products, so a quick measurement can prevent selecting a tire that suits the diameter but not the full wheel specification.

Yes. The 1966 Humber Super Snipe Base follows the same two primary fitment paths as the model overall: 185R15 as a radial option and 775-15 as a bias-ply option, both for 15-inch rims. The sub-model does not introduce a separate wheel diameter or a different primary size family.

That means the decision is really about the car's current setup and your intended use. A restoration-minded owner may stay with the traditional 775-15 bias-ply size, while a driver-oriented car may already be on 185R15 radials. Looking at the tires now on the car, along with wheel width and clearance, is the best way to narrow the choice.

775-15 is a bias-ply tire size for the 1966 Humber Super Snipe. It uses the older numeric bias-ply sizing system, and the available products in this size are bias-ply tires rather than standard radial tires. The radial fitment path on this car is handled separately through 185R15.

That difference matters because construction affects both appearance and setup. A car kept on 775-15 bias-ply tires can retain a more traditional period-style look, especially with sidewall treatments such as blackwall, whitewall, redline, or goldline. Before changing away from bias-ply, verify wheel width, check clearances, and decide whether the goal is original-style presentation or a radial driving format.

Radial equivalents for 775-15 include 195R15, P205/75R15, P215/70R15, and 670R15. In that group, 195R15 is the 80-series metric radial equivalent, P205/75R15 is the 75-series P-metric radial equivalent, P215/70R15 is the 70-series P-metric radial equivalent, and 670R15 is the bias-look radial alternative.

Each of those sizes gives you a different way to approach a radial conversion while staying in the 15-inch rim family. The associated rim-width range is 5-7 inches, which is useful when checking wheel suitability. Even so, an equivalent should still be compared against the car's actual wheel, clearance, and overall setup before treating it as the right choice.

Yes, a bias-look radial equivalent is available for the 775-15 size used on the 1966 Humber Super Snipe. That size is 670R15, and it is separate from the conventional metric and P-metric radial equivalents such as 195R15, P205/75R15, and P215/70R15.

A bias-look radial is worth considering when the goal is to move toward radial construction without giving up a traditional visual presentation. It still needs the same fitment review as any other conversion choice, including wheel width, overall dimensions, and clearance around suspension and bodywork. The best candidate is a car whose wheel setup has been confirmed rather than assumed.

Start with the role the car plays. A 775-15 tire on a 1966 Humber Super Snipe keeps you in the bias-ply size family, so the main factors become sidewall appearance, brand, tire series, and wheel-width suitability. Available choices span BFGoodrich, Firestone, and Goodyear, with several different visual treatments.

A period-style touring presentation may point one way, while a more sporting or display-focused look may point another. It also helps to compare load figures and rim-width specifications where they are shown, rather than choosing by sidewall style alone. That approach keeps the decision centered on both the visual character of the Humber and the mechanical realities of its wheel setup.

The 1966 Humber Super Snipe has a wide spread of sidewall choices across its two primary sizes. Depending on the size and product selected, available styles include blackwall, narrow whitewall, redline, goldline, blue dot, and raised white letter blue streak. The radial 185R15 range is narrower, while 775-15 bias-ply choices are especially varied.

That sidewall choice changes the visual tone of the car more than many buyers expect. A plain blackwall gives the Humber a restrained look, while whitewall, redline, or goldline treatments add a stronger mid-century character. Since sidewall style does not override basic fitment, choose the correct size and construction first, then narrow the field by the presentation that best suits the car.

Tires for the 1966 Humber Super Snipe are available from Coker Classic, Michelin, Avon, Universal Vintage Tire, BFGoodrich, Firestone, and Goodyear. Those brands cover both of the car's primary fitments, with radial offerings concentrated in 185R15 and bias-ply offerings concentrated in 775-15.

Brand choice should be used as one part of the decision rather than the whole decision. First confirm whether the car needs the radial 185R15 path or the bias-ply 775-15 path, then compare the tire series, sidewall treatment, and wheel-width details within that size family. That keeps the selection process focused on fitment and use, not just on the name molded into the sidewall.

For a period-style 1966 Humber Super Snipe, the 775-15 bias-ply size is the most traditional-looking starting point because it preserves the vintage sizing system and opens the widest range of classic sidewall treatments. Blackwall, narrow whitewall, redline, goldline, blue dot, and raised white letter blue streak options all appear in that size family.

A buyer aiming for a more road-friendly radial presentation can still keep a vintage flavor by using 185R15 or by evaluating the 670R15 bias-look radial alternative to 775-15. If strict originality matters, compare the tire choice against marque-specific historical references and restoration documentation, since period-style appearance and exact factory delivery are not always the same thing.

Tire construction changes the look of a restored 1966 Humber Super Snipe as much as it changes the driving setup. A 775-15 bias-ply tire gives the car a more traditional visual character, especially when paired with classic sidewall treatments, while a 185R15 radial usually presents a more modern interpretation of the same 15-inch wheel diameter.

That visual shift matters on a Humber because the car's formal lines respond strongly to tire profile and sidewall style. Buyers restoring for shows, touring, or mixed use should think about whether they want a distinctly vintage presentation or a radial-based look with less visual nostalgia. Construction should be chosen as part of the restoration plan, not as an afterthought.

Yes, modifications can affect tire fitment on a 1966 Humber Super Snipe even when the tire size itself is correct. Changes to wheel width, wheel design, suspension height, steering components, or body clearance can alter how either 185R15 or 775-15 sits and moves through its full range of travel.

A car with aftermarket wheels or suspension work deserves a hands-on check before tires are chosen. Measure the wheel, inspect inner and outer clearances, and look for signs of rubbing at full steering lock and normal suspension movement. Those checks become even more important when evaluating a radial equivalent for 775-15, because similar rim diameter does not eliminate other fitment variables.

Before driving a 1966 Humber Super Snipe on new tires, inspect the wheels, valve stems, lug hardware, and the general condition of the suspension and steering. Make sure the tires are inflated appropriately for the chosen product, and look over the car for any obvious clearance concerns around fenders, suspension parts, and steering components.

A short initial road test is worthwhile even after everything appears correct. Pay attention to pull, vibration, unusual contact noises, and any sign that the tire is touching bodywork under turning or compression. Collector cars that sit for long periods also benefit from a recheck after the first drive, since fresh tires can reveal wheel or chassis issues that old tires were masking.

775-15 tires on a collector 1966 Humber Super Snipe should be maintained with regular pressure checks, routine visual inspections, and careful storage habits. Look for sidewall cracking, cuts, bulges, irregular tread wear, and signs of air loss, especially if the car is driven infrequently or spends long periods parked between outings.

Storage conditions matter almost as much as mileage on a low-use Humber. Keeping the car away from prolonged heat, direct sunlight, standing moisture, and ozone sources helps protect the tires over time. It is also smart to inspect the tires before every longer drive, since collector vehicles can accumulate age-related tire problems even when tread depth still looks serviceable.
