1962 Jensen Tire Fitment Guide

1962 Jensen vehicles in this range use two tire sizes, and both apply to the Jensen C: 185R15 and 670-15. Both sizes mount on 15-inch rims, but they do not share the same construction. The 185R15 is a radial size with product fitments covering rim widths from 4.5 to 6.5 inches depending on the tire, while 670-15 is a bias-ply size with product fitments ranging from 4.5 to 6.0 inches depending on the brand and version.

That means the first step is not identifying a different model, but deciding which tire philosophy fits your car and goals. A Jensen C restored toward period appearance will often point buyers toward 670-15, while owners who prioritize a later-style radial feel may gravitate to 185R15. Before ordering, compare your actual wheel width to the approved range for the exact tire you want, because compatibility can change within the same nominal size.

On a 1962 Jensen, 670-15 is a numeric bias-ply size. The 6.70 figure refers to the tire's nominal section width in inches, and the 15 identifies the wheel diameter in inches. Unlike a modern metric radial code, there is no radial "R" in the designation, and the size belongs to the older numeric system widely used on classic cars of this era.

That older sizing format matters because it usually goes hand in hand with the visual profile and driving character many restorers want on an early-1960s British grand tourer. If your goal is a traditional look with blackwall or wide whitewall choices, 670-15 is the size to investigate first. You should still check the approved rim-width range of the exact brand and sidewall style you prefer, because those details can differ across bias-ply offerings.

On a 1962 Jensen, 185R15 is a Euro-metric radial size. The 185 denotes a nominal section width of 185 millimeters, the R identifies radial construction, and the 15 is the wheel diameter in inches. In this style of older metric sizing, the aspect ratio is not written out, and it is conventionally treated as an 80-series radial format.

That code signals a different tire era and a different ownership choice than 670-15. Buyers looking for radial construction, including blackwall, narrow whitewall, or redline treatments, will usually start here. Within 185R15, details such as speed rating and approved rim-width range can change by product, so it is smart to match the exact tire to how the car will be driven rather than assuming every 185R15 version is interchangeable in every respect.

For a 1962 Jensen C, the main difference is construction and the character that comes with it. The 670-15 is a bias-ply size that aligns closely with the period look and feel expected on an early-1960s car, while the 185R15 is a radial size that reflects a more modern tire format on the same 15-inch wheel diameter. Both are valid paths for the Jensen C, but they point toward different priorities.

A show-focused or authenticity-minded restoration will often lean toward 670-15, especially if the sidewall look is part of the car's presentation. A driver that sees more regular road use may be better served by starting with the 185R15 radial options and then narrowing the choice by sidewall style and speed rating. The key is to decide whether originality or later-style road manners is more important before comparing individual tires.

1962 Jensen tires are available in several sidewall styles across the two sizes. The 185R15 radial range includes redline, narrow whitewall, and blackwall versions. The 670-15 bias-ply range includes blackwall and wide whitewall choices. That gives the Jensen C owner room to match the tire not only to construction preference, but also to the visual tone of the restoration.

For an early-1960s British GT car, blackwall is often the safest starting point for an understated factory-era appearance, while a narrow whitewall or redline can push the car in a more individualized direction depending on market taste and restoration theme. Wide whitewalls are available in 670-15 if your car is being styled with a stronger period accent. If authenticity matters for judging, compare your chosen sidewall treatment against marque-club guidance and period photos of similar cars.

1962 Jensen vehicles have coverage from several brands across the two sizes. The 185R15 radial is available from Coker Classic and Michelin. The 670-15 bias-ply is available from Firestone, US Royal, Coker Classic, and Universal Vintage Tire. That mix gives Jensen C owners access to both traditional American-brand styling cues and established European radial offerings within the same year-and-make fitment range.

Brand choice should come after you settle on size and construction, not before. A buyer pursuing a radial 185R15 may focus on Michelin's blackwall or narrow whitewall options or Coker Classic's redline version, while a buyer staying with 670-15 can compare Firestone, US Royal, Coker Classic, and Universal by sidewall style and approved wheel range. Once the tire type is decided, brand becomes a more meaningful way to narrow the final selection.

Rim-width requirements for 1962 Jensen tires depend on the exact size and tire version. Within 185R15, approved rim widths run from 4.5 to 6.5 inches depending on the product, with some tires fitting 4.5 to 6.0 and others 5.0 to 6.5. Within 670-15, approved rim widths run from 4.5 to 6.0 inches depending on the brand, with some versions suited to 4.5 to 5.0 and others to 5.0 to 6.0.

That variation is important because two tires with the same nominal size do not always share the same wheel-range window. Measure your actual wheel width before finalizing a choice, especially if the car has replacement rims or a long restoration history. If your Jensen C still has original-style wheels, use the exact product's approved range as the deciding reference rather than assuming any 15-inch tire in the correct nominal size will sit correctly.

Tube requirements are not the same across the 1962 Jensen size range. The 185R15 radial options here are tubeless, with Michelin versions specifically marked TL. The 670-15 bias-ply options do not carry a tubeless or tube-type marking in the available specifications, so the correct setup should be confirmed against the actual wheel design and the exact tire's sidewall information.

That matters most on an older car because wheel construction and condition play a big role in whether a tubeless tire is appropriate in practice. If your Jensen C uses original or older restored wheels, inspect them carefully for bead-seat condition, valve-stem integrity, and overall airtightness before assuming any setup. When there is any doubt, match the tire's sidewall marking and manufacturer guidance to the wheel you actually plan to use.

A 1962 Jensen C can often use the same original wheels with both 185R15 and 670-15 because both sizes share a 15-inch rim diameter. Rim diameter alone, however, is only part of the story. The exact wheel width still needs to fall within the approved range of the specific tire, and those ranges differ across both the radial and bias-ply choices.

In practical terms, the shared 15-inch diameter makes this a realistic comparison for many Jensen owners, but wheel width decides whether a specific tire is a sound match. Before changing from bias-ply to radial or vice versa, measure the wheel and compare it against the tire you have in mind. That simple step helps avoid sidewall shape problems, compromised handling feel, or an appearance that does not suit the proportions of the car.

A 1962 Jensen should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment. Keep the tires clean and properly inflated, and move the car periodically if it will sit for long stretches. Because the Jensen C can run either bias-ply or radial tires, it is worth noting that bias-ply tires generally develop temporary flat-spotting more readily during static storage than radials.

If the car will be parked for months at a time, rolling it a short distance every few weeks can help reduce stress concentration in one contact patch. For extended storage, some owners also use tire cradles or place the vehicle on stands while keeping the suspension appropriately supported. Good storage habits matter as much as miles driven on collector cars, especially when the sidewalls are chosen partly for appearance and originality.

On a 1962 Jensen, tire age is usually more important than mileage because collector cars often spend far more time parked than driven. A sound rule is to begin evaluating tires closely once they reach about five to seven years of age and to treat ten years as a strong point for replacement consideration regardless of remaining tread. The DOT date code on the tire helps establish age, and that should be part of the car's maintenance record.

A Jensen C that sees occasional weekend use may still have tires that look decent long after their safest service life has begun to close. Sidewall cracks, hardening rubber, repeated pressure loss, and vibration are all warning signs even when tread depth appears acceptable. Age-based replacement is especially important on specialty tires, where preserving the car's manners and appearance should never come at the expense of ignoring rubber that has simply grown old.

Tires on a 1962 Jensen should be checked before every drive and inspected more carefully before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, and any sign that the car is losing pressure between drives. If your Jensen C is running older-style wheels or a setup that may use tubes, valve stems and related sealing components deserve close attention as part of the inspection routine.

Frequent checks matter because collector cars often sit long enough for small issues to grow quietly between use cycles. A short pre-drive walkaround can catch low pressure, weather-checking, or a damaged sidewall before the car reaches speed. Before tours or highway trips, add a pressure check, inspect the spare, and make sure the tires on the car still match as a complete set in size, construction, and general condition.

A 1962 Jensen C would have belonged to an era when bias-ply construction was still the standard original-equipment expectation on most production cars, including specialist British makes. Within the available fitments here, 670-15 is the size that most naturally reflects that period construction. The 185R15 radial is a valid fitment option for the car today, but it represents a later-style radial path rather than the default early-1960s factory norm.

If you are restoring a Jensen C with originality as the first priority, start by evaluating 670-15 and then narrow the choice by blackwall versus whitewall presentation. If your car has a specific export-market history or unusual restoration target, consult marque-club material and period photography before finalizing sidewall treatment. Those resources are often the best way to sort out details that go beyond broad era-correct construction type.

Correct tire fitment absolutely matters when showing a 1962 Jensen, especially in judged settings that care about authenticity. Size, construction type, and sidewall appearance all affect whether the car looks convincingly of its period. On an early-1960s Jensen C, a modern radial in the right diameter may still be viewed differently from a proper bias-ply if the event emphasizes originality over road-use practicality.

That does not mean one choice is universally right for every owner; it means the intended use of the car should shape the tire decision. For concours-style presentation, pay close attention to whether blackwall, narrow whitewall, redline, or wide whitewall makes sense for the car's restoration theme and market history. Marque clubs and event rulebooks are the right authorities for fine-point judging standards, especially when authenticity will be scored closely.

Within the 185R15 radial fitments for 1962 Jensen, Michelin XVS and Coker Classic radial options differ in sidewall presentation, speed rating availability, and wheel-range details. Michelin XVS appears in blackwall and narrow whitewall form, with H-rated and V-rated versions and approved rim-width ranges spanning 4.5 to 6.5 inches depending on the exact tire. The Coker Classic radial appears here as a redline 185R15 with a 5.0 to 6.5-inch approved rim-width range and a published load figure of 1355 pounds at 35 psi.

That makes the comparison less about basic fitment and more about the final character you want from the car. A Jensen C owner seeking a European-style radial presentation may naturally compare the Michelin options first, while someone wanting a redline look on a radial construction may focus on the Coker Classic. Once sidewall appearance and intended driving speed are clear, the remaining decision usually comes down to which exact specification best suits your wheels.

1962 Jensen tires can be suitable for highway driving when they are correctly sized, in sound condition, and used within the limits of their construction and speed rating. In the radial 185R15 range, Michelin options include H-rated tires with a 130 mph ceiling and V-rated tires with a 149 mph ceiling. The 670-15 bias-ply choices do not carry a speed letter here, so they should be treated as traditional bias-ply collector tires rather than as modern high-speed performance tires.

On a Jensen C, tire capability is only one part of the highway question. Brake condition, steering, suspension, alignment, and the overall mechanical health of a low-production early-1960s GT car matter just as much at normal road speeds. If the car will spend meaningful time on modern highways, many owners begin by considering the radial 185R15 options, then confirming wheel compatibility and choosing a speed rating that matches how the car is actually driven.

Inflation pressure for a 1962 Jensen should not be guessed from size alone. Within the available fitments, the Coker Classic 185R15 radial carries a published load figure of 1355 pounds at 35 psi, while several 670-15 bias-ply options show 1450 pounds at 32 psi and another reaches 1550 pounds at 32 psi. Those figures describe the tire's rated load relationship at a stated pressure, but they are not automatically the same thing as the car's ideal operating pressure.

For the best result, use the factory guidance for the car as your baseline and then compare it with the tire maker's specifications for the exact reproduction or radial tire you choose. Do not transfer a pressure number from 670-15 to 185R15 or vice versa simply because both fit a 15-inch wheel. Construction type, sidewall design, and intended use all influence where the tire performs properly on the car.

Before a longer drive in a 1962 Jensen, inspect each tire for cracks, cuts, bulges, uneven wear, and any sign of pressure loss. Confirm that all four tires match in size and construction, verify cold pressures, and examine the valve stems closely. If the car is running older wheels or a setup that may involve tubes, the sealing components and the spare tire deserve the same attention as the road tires.

A Jensen C should also be treated like the hand-built early-1960s grand tourer it is, so the tire inspection ought to be part of a wider mechanical check. Look over brakes, steering play, fluid levels, cooling condition, and wheel fastener security before setting out. Long drives are where age-related issues tend to appear, and a careful pre-trip inspection greatly reduces the chance that a small garage-level problem turns into a roadside interruption.
