1962 Jensen C Tires

The 1962 Jensen C uses two primary tire sizes: 185R15 in radial construction and 670-15 in bias-ply construction. Both sizes are built for 15-inch wheels, so the fitment decision is centered more on construction type, tire profile convention, and desired appearance than on changing rim diameter.

A Jensen C owner should first confirm which setup is actually on the car now, especially if wheels or tires have been changed over the years. Once that is established, the next step is choosing within the correct size based on sidewall style, brand, and whether the goal is a traditional bias-ply presentation or a radial-format alternative.

The 1962 Jensen C uses a 15-inch rim diameter with both of its primary tire fitments. That applies to the 670-15 bias-ply size and the 185R15 radial size, so the wheel diameter remains consistent even though the tire sizing systems are different.

Rim diameter alone is only part of the fitment picture. Wheel width should still be checked before selecting a specific tire, especially when comparing a narrow vintage bias-ply fitment to a radial or evaluating one of the radial equivalents for 670-15, since construction and section shape can change how a tire sits on the wheel.

670-15 is a vintage numeric bias-ply tire size. The 670 portion refers to an approximate 6.70-inch nominal section width, and the 15 identifies the wheel diameter in inches. On a 1962 Jensen C, it represents the traditional bias-ply fitment style rather than a modern metric radial size designation.

That matters because a 670-15 tire is chosen differently than a modern radial. Sidewall styling, brand character, wheel width suitability, and the car’s intended use all become important, and a Jensen that has been converted to radial tires should not be assumed to need the same construction just because the wheel diameter remains 15 inches.

670-15 is a bias-ply tire size for the 1962 Jensen C. It uses the older numeric bias-ply sizing convention and is distinct from the car’s radial-format 185R15 option, even though both are intended for 15-inch wheels.

Choosing 670-15 keeps the car in a traditional construction style and opens up a wide range of blackwall, narrow whitewall, and wide whitewall choices. Moving away from it toward a radial setup should be treated as a separate fitment decision, with attention paid to wheel width, vehicle stance, and clearance rather than assuming the change is automatically compatible.

Radial equivalents for 670-15 include 195R15 as an 80-series metric radial, P205/75R15 as a P-metric 75-series radial, P215/70R15 as a P-metric 70-series radial, and 670R15 as a bias-look radial equivalent. These give the 1962 Jensen C owner several ways to compare a radial alternative to the original bias-ply sizing.

Each of those alternatives should be evaluated as a candidate size rather than an automatic substitute. A 5-7 inch rim-width range is associated with the equivalent group, and the actual wheel width, overall tire dimensions, and body or steering clearance should all be reviewed before converting the car from its 670-15 bias-ply setup.

A 670R15 bias-look radial can be considered for a 1962 Jensen C as a radial equivalent to the 670-15 bias-ply size. Its role is different from a standard metric radial because it is intended to offer radial construction while retaining a more traditional tire presentation.

That makes it especially relevant for owners who want to stay closer to the car’s vintage visual character without remaining on full bias-ply construction. Even so, the same checks still apply: wheel width, overall dimensions, steering travel, and fender clearance should be verified on the actual car before treating a bias-look radial as the right path.

A 670-15 tire for a 1962 Jensen C should be chosen first by confirming that bias-ply construction is the intended direction. From there, the main considerations are sidewall style, brand, tire series, and wheel-width suitability, since this size is available in blackwall, narrow whitewall, and wide whitewall forms across several vintage-style product lines.

The right pick depends on how the car will be presented and driven. A restoration-oriented Jensen may lean toward a traditional sidewall treatment, while a car meant for general road use may call for careful comparison of rim-width specifications and load figures where they are stated, rather than selecting by appearance alone.

The 1962 Jensen C has meaningful sidewall variety across its available tire choices. Depending on size and series, options include blackwall, narrow whitewall, wide whitewall, and redline, with the broadest variety appearing in the 670-15 bias-ply size and redline options appearing in the 185R15 radial category.

That variety allows the tire to influence the car’s look almost as much as the wheel does. A restrained blackwall gives a cleaner sporting appearance, whitewalls shift the car toward a more formal early-1960s presentation, and redlines offer a more distinctive period-style accent, but any choice should still start with the correct tire size and construction.

Tires for the 1962 Jensen C are available from several brands, including Michelin, Avon, Coker Classic, Universal Vintage Tire, Firestone, BFGoodrich, US Royal, Goodyear, Excelsior, and STA. Brand availability varies by tire size, with the 185R15 radial and 670-15 bias-ply categories each drawing from a different mix of product lines.

Brand choice is best used as one part of the selection process rather than the whole decision. It helps more to compare the actual size, construction, sidewall style, tire series, and wheel-width requirements within the brands that offer the fitment you want than to pick a name first and try to force the car into that option.

For a period-style 1962 Jensen C, the 670-15 bias-ply fitment is the natural starting point because it preserves the vintage sizing system and construction style associated with the car’s era. Within that size, blackwall, narrow whitewall, and wide whitewall choices allow the appearance to be tuned without moving away from the traditional format.

A radial can still suit a restoration-minded car, particularly if the goal is to balance vintage proportions with a later-style radial setup. When exact originality matters, the safest approach is to compare the tire choice against marque references, period photography, or build-specific documentation instead of assuming any current sidewall treatment was used when the car was new.

Tire construction changes the look of a restored 1962 Jensen C as much as it changes the driving setup. A 670-15 bias-ply tends to support a more traditional early-1960s visual impression, while a 185R15 radial or a radial equivalent can shift the car toward a slightly more modernized presentation even when the wheel diameter remains 15 inches.

That difference is why restoration planning should treat construction as an appearance decision as well as a fitment decision. Sidewall treatment then refines the final result, whether the car is being kept understated with blackwalls or given a more formal period-style look with whitewalls, but the size and construction should be settled before those details.

Modifications can absolutely affect tire fitment on a 1962 Jensen C. Even though the primary sizes use 15-inch rims, aftermarket wheels, different wheel widths, suspension changes, altered ride height, or bodywork differences can all influence how a 670-15, 185R15, or radial equivalent sits and clears the car.

Any Jensen that has been changed from its original wheel or suspension setup deserves a close fitment check before new tires are selected. Wheel width, steering clearance, fender clearance, and the space available at full suspension movement matter more once the car departs from a stock-style configuration, especially when switching from bias-ply to radial construction.

Before driving a 1962 Jensen C on new tires, inspect the wheels for correct diameter and condition, confirm proper tire pressure, and look over the rest of the chassis for anything that could affect tracking or clearance. It also makes sense to verify that the tires are seated properly and that there is no interference at full steering lock.

A collector car benefits from a broader once-over before road use. Brake function, suspension wear, alignment condition, and any signs of rubbing should be checked early, and the first miles should be treated as a settling-in period so the tires can be rechecked for pressure stability, clearance, and general behavior on the car.

Tires on a collector 1962 Jensen C should be maintained with regular pressure checks, routine visual inspection, and attention to age-related condition as well as tread. Low-mileage cars often spend long periods parked, which makes sidewall cracking, flat spotting, air loss, and unnoticed weathering just as important as visible tread wear.

Good storage habits help preserve both bias-ply and radial tires. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources is useful, and moving it periodically can help reduce stress from sitting in one position. Any tire showing cuts, bulges, severe cracking, or persistent pressure loss deserves closer evaluation before the car is driven.
