1967 Triumph 2000 Tires

The 1967 Triumph 2000 uses two primary tire sizes: 175R13 in radial construction and 650-13 in bias-ply construction. Both sizes are built for a 13-inch rim, so the key difference is not wheel diameter but the tire-sizing system and construction style used on the car.

That means the first step is confirming whether the car is currently set up for bias-ply or radial tires. A restored car kept close to period appearance may stay with 650-13, while a car already running radial-type fitment may use 175R13. Wheel width, clearance, and any previous wheel changes are worth checking before choosing between the two.

The 1967 Triumph 2000 uses a 13-inch rim with both of its primary tire sizes. That applies whether the car is fitted with the 650-13 bias-ply size or the 175R13 radial size, so rim diameter stays consistent across the covered fitment choices.

Rim diameter alone does not settle the full fitment question, because wheel width still matters when selecting a tire. The available 650-13 bias-ply products are built around relatively narrow wheel widths, and radial alternatives should also be checked against the actual wheel on the car. Measuring the wheel already installed is a smart step on any older vehicle.

Yes. The 1967 Triumph 2000 Sport uses the same two tire-size paths: 175R13 in radial construction and 650-13 in bias-ply construction. Like the model core, both fitment routes stay on a 13-inch rim rather than changing to a different wheel diameter.

That keeps sub-model confusion to a minimum, but the car still needs to be matched to its current setup. A Sport that has remained restoration-oriented may be a strong candidate for the 650-13 bias-ply size, while a car already using radial-style fitment may point you toward 175R13 or another equivalent radial option after wheel and clearance checks.

On the 1967 Triumph 2000, 650-13 is the bias-ply tire size. It uses a vintage numeric bias-ply sizing format and represents the traditional construction choice for this car, while 175R13 is the radial-format size associated with the same 13-inch rim diameter.

That distinction matters because construction affects both presentation and setup decisions. A buyer choosing 650-13 should focus on period-style appearance, available whitewall treatments, and wheel-width compatibility. Anyone moving away from bias-ply should compare radial-equivalent sizes carefully instead of assuming every 13-inch radial will behave the same on the car.

Radial equivalents for 650-13 include 175R13, P175/75R13, P185/70R13, and 650R13. In that group, 175R13 is the 80-series metric radial equivalent, P175/75R13 is the 75-series P-metric option, P185/70R13 is the 70-series P-metric option, and 650R13 is the bias-look radial equivalent.

Those choices give the 1967 Triumph 2000 owner several ways to compare profile and visual style without leaving the 13-inch rim format. The recommended rim-width range for the equivalent path is 4 to 6 inches, and the final choice should be checked against the car's wheel width, suspension condition, and available clearance rather than treated as automatic interchangeability.

Start by confirming the wheel diameter and actual wheel width on the car, then compare the radial-equivalent size you are considering against the existing setup. For a 650-13 fitment, the radial-equivalent path includes 175R13, P175/75R13, P185/70R13, and 650R13, with a recommended rim-width range of 4 to 6 inches.

A conversion also deserves a close look at fender and steering clearance, suspension condition, and how the car will be used. Some owners prioritize traditional appearance, while others want a radial alternative that still suits the car's dimensions. On an older Triumph, previous wheel or suspension changes can matter as much as the tire size itself.

Begin with the role the tire needs to play on the car. A 650-13 tire for the 1967 Triumph 2000 is a bias-ply fitment, so the main considerations are maintaining a traditional look, matching the tire to the wheel width in use, and deciding which sidewall presentation suits the car best.

Available 650-13 choices also vary by brand, tire series, and whitewall style rather than by size alone. Coker Classic and US Royal offerings share the same general fitment category, but buyers can still compare wide whitewall versus narrow whitewall appearance, classic bias-ply series identity, and load specifications before deciding what best fits the car's purpose.

For the available 650-13 products used on the 1967 Triumph 2000, the sidewall choices are narrow whitewall and wide whitewall. Both treatments appear in classic bias-ply offerings, giving the car owner room to shape the visual presentation without changing the basic tire size.

That choice is mostly about appearance, especially on a restoration-minded sedan where sidewall detail makes a visible difference. A wide whitewall creates a more pronounced vintage look, while a narrow whitewall keeps the presentation subtler. The best match depends on the car's trim, stance, and restoration direction rather than any universal rule about what every Triumph 2000 should wear.

The 650-13 bias-ply fitment for the 1967 Triumph 2000 is available from Coker Classic and US Royal. Both brands appear in classic bias-ply series with whitewall variations, so the comparison is less about size differences and more about visual treatment within the same fitment category.

A buyer choosing between them should focus on the tire series offered, sidewall style, and whether the overall look matches the car's intended presentation. Since both remain within the same basic 650-13 bias-ply format, wheel-width compatibility and the appearance goal of the vehicle usually matter more than the brand name alone.

For a period-style 1967 Triumph 2000, the 650-13 bias-ply size is the natural starting point because it preserves the vintage numeric sizing format and traditional construction. Available options also include narrow whitewall and wide whitewall versions, which lets the owner shape the car's visual character without moving away from bias-ply fitment.

The right choice depends on how strictly the car is being restored and what appearance you want from the finished sedan. If exact historical accuracy matters, marque-specific references and period photos are worth checking before choosing a whitewall width. For many owners, the goal is a convincing period-style presentation rather than an unsupported claim of factory originality.

Tire construction changes the look of a restored 1967 Triumph 2000 more than many buyers expect. A 650-13 bias-ply tire presents the car in a more traditional visual language, especially with whitewall options, while a radial-format choice such as 175R13 tends to give the car a more modernized fitment impression.

That does not automatically make one choice right and the other wrong; it depends on the restoration goal. A car aimed at authentic vintage character usually leans toward bias-ply presentation, while a driver-oriented restoration may consider a radial route. Sidewall treatment, wheel width, and stance all influence the final look alongside the construction type itself.

Yes. Modifications can affect tire fitment on a 1967 Triumph 2000 even when the tire size itself seems correct. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body repairs can all influence whether a 650-13 bias-ply or 175R13 radial setup has the clearance and wheel support it needs.

That is why the actual car should be checked instead of relying only on year-make-model identification. Measuring the installed wheel, looking at inner and outer clearance, and confirming steering travel can prevent surprises. On older cars, decades of changes by previous owners often matter as much as the original fitment pattern.

Before driving a 1967 Triumph 2000 on new tires, inspect the wheels, valve stems, lug hardware, and visible suspension components. The tires themselves should also be checked for proper seating, inflation, and any obvious interference at full steering lock, especially if the car has changed from one construction type to another.

A short, careful test drive is a sensible next step on a collector-era sedan. Listen for rubbing, feel for vibration, and recheck air pressure after the first miles. It also helps to look over the older braking and steering systems at the same time, since fresh tires often reveal problems that worn or aged tires had been masking.

650-13 tires on a collector 1967 Triumph 2000 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Bias-ply collector tires deserve close attention for sidewall cracking, cuts, bulges, uneven wear, or slow air loss, especially on cars that spend long periods parked between drives.

Good storage conditions help as much as mileage-based maintenance. Keeping the car away from prolonged sunlight, moisture, excess heat, and ozone-producing equipment can help preserve the tires' condition over time. Even a seldom-driven car should have its tires inspected routinely, because age and storage environment can matter just as much as road use.
