1970 Lotus Europa Tires

The 1970 Lotus Europa uses two primary tire sizes: 560-13 in bias-ply construction and 155R13 in radial construction. Both sizes fit a 13-inch rim, so the fitment question is less about wheel diameter and more about which construction and size format matches the car’s current setup and the owner’s goals.

That distinction matters because a 560-13 bias-ply tire and a 155R13 radial do not present the same way even though they share the same rim diameter. Checking the actual wheels on the car, the intended appearance, and any prior wheel or suspension changes will help narrow the choice before moving on to brand, sidewall style, or tire series.

The 1970 Lotus Europa uses a 13-inch rim with both of its primary tire sizes. That applies to the 560-13 bias-ply fitment and the 155R13 radial fitment, so the wheel diameter remains consistent even though the tire sizing systems and construction types are different.

Rim diameter is only the starting point, because wheel width still affects which tire makes sense on the car. Before selecting a tire, it helps to confirm the actual wheel width, especially if the Europa has had replacement wheels fitted over the years, since a radial and a bias-ply option can have different rim-width requirements.

The 1970 Lotus Europa Base is associated with both 155R13 radial and 560-13 bias-ply sizes. In practical terms, that means the Base model is not locked to a single primary size format, and the buyer may be choosing between a radial fitment and a traditional bias-ply fitment on the same 13-inch wheel diameter.

That shared sub-model fitment shifts the decision away from trim differences and toward the tire itself. A restoration-oriented owner may focus on the period-style look of 560-13, while a driver evaluating radial options may start with 155R13 and then compare wheel width, tire profile, and the car’s overall stance before making a final selection.

On the 1970 Lotus Europa, 560-13 is a bias-ply tire size. It uses a vintage numeric bias-ply format, with 560 indicating the nominal section-width class and 13 identifying the rim diameter. That makes it the traditional construction choice among the two primary Europa fitments.

Choosing 560-13 usually means focusing on a more traditional presentation and selecting among available whitewall styles and bias-ply series. It is still important to verify wheel width before purchase, because the available 560-13 products do not all share the same rim-width range, and older cars may no longer have their original wheel setup.

Radial equivalents for 560-13 include 155R13, P155/75R13, and P155/70R13. Those choices represent three different radial sizing approaches: an 80-series Euro-metric radial, a 75-series P-metric radial, and a 70-series P-metric radial. Each is an alternative format tied to the original 560-13 size family.

The recommended rim-width range attached to this equivalency group is 4 to 5 inches, which makes wheel confirmation especially important before any conversion. Even when the rim diameter remains correct, overall tire dimensions and clearance still need to be checked against the Europa’s wheelhouse, steering movement, and current suspension condition.

That choice depends on how the 1970 Lotus Europa is being used and how closely the owner wants to stay with a traditional presentation. The car is associated with both 560-13 bias-ply and 155R13 radial fitments, so either path starts from a recognized primary size rather than from an improvised substitute.

A buyer aiming for a more period-style look may lean toward the bias-ply size, while someone prioritizing a radial construction may begin with 155R13 or evaluate the radial equivalents tied to 560-13. The key step is confirming wheel width and checking clearance, since construction choice should still suit the car’s actual wheels and setup.

Start with the correct primary size and construction for the direction of the car. The 1970 Lotus Europa is associated with 560-13 bias-ply and 155R13 radial fitments, both on 13-inch rims, so the first decision is whether the goal is a traditional bias-ply look or a radial tire in a Euro-metric format.

After that, compare the details that affect actual selection: wheel width, sidewall style, brand, and tire series. A whitewall bias-ply creates a very different visual result from a blackwall radial, and the available products also vary in rim-width ranges and load figures, so the best choice depends on both appearance goals and wheel compatibility.

The available sidewall styles for 1970 Lotus Europa tires include blackwall in the 155R13 radial fitment, along with narrow whitewall and wide whitewall choices in 560-13 bias-ply form. That gives the car a clear split between a more understated radial appearance and a more visibly vintage whitewall presentation.

Sidewall style should be matched to the look the owner wants from the finished car rather than treated as a minor detail. A blackwall radial suits a cleaner sporting presentation, while narrow or wide whitewalls push the car toward a more restoration-oriented appearance, so it helps to choose style and construction together instead of separately.

The 1970 Lotus Europa has tire options from Michelin and Dunlop in 155R13 radial fitment, plus BFGoodrich and Firestone in 560-13 bias-ply fitment. Those brands are spread across different constructions and tire series, so the brand question is tied closely to whether the buyer is choosing radial or bias-ply tires.

Comparing by brand works best after size and construction have already been settled. Once that is clear, the real differences become sidewall treatment, tire series character, and wheel compatibility, rather than brand name alone, especially on a car as visually sensitive to tire choice as the Europa.

A period-style 1970 Lotus Europa usually starts with the 560-13 bias-ply fitment, because it preserves the vintage size format and opens the door to traditional whitewall presentations. That does not automatically make every available 560-13 tire historically exact for every restoration, but it is the natural starting point for a more traditional look.

The final choice should reflect how authentic the restoration needs to be and how the car will be used once completed. When originality matters down to specific appearance details, marque-club references and period photographs can help narrow the right look, while the available sidewall treatments help shape the finished stance and character.

Tire construction changes more than road feel on a restored 1970 Lotus Europa; it also changes the car’s visual character. A 560-13 bias-ply tire presents in a more traditional vintage style, especially with whitewall options, while a 155R13 radial blackwall gives the car a later, more understated sporting appearance.

That visual difference is worth deciding early in a restoration, because wheels, stance, and trim details all read differently once the tires are mounted. Owners trying to capture a distinctly period presentation often choose construction and sidewall style together so the finished car looks intentionally restored rather than mixed between eras.

Yes, modifications can affect tire fitment on a 1970 Lotus Europa even when the tire size itself is correct. Changes such as aftermarket wheels, different wheel widths, altered offset, lowered suspension, or bodywork repairs can all influence how a 560-13 or 155R13 tire sits within the car’s limited available space.

A modified Europa should be checked at full steering movement and through suspension travel before settling on a tire. The fact that both primary sizes use a 13-inch rim does not remove the need to verify wheel width and clearance, especially on a compact sports car where small dimensional changes can have visible effects.

Before driving a 1970 Lotus Europa on new tires, inspect the wheels for correct diameter and width, confirm the tires are seated properly, and check inflation pressure. It is also wise to look over suspension and steering components, since worn bushings, loose hardware, or alignment issues can affect how a lightweight car responds on fresh tires.

A short initial road test should focus on vibration, rubbing, pulling, or unexpected contact under steering input. After a brief drive, recheck air pressure and look again for any clearance marks, because the Europa’s compact packaging leaves less margin for unnoticed fitment issues than a larger collector car.

Collector-car tires on a 1970 Lotus Europa should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Whether the car wears 560-13 bias-ply tires or 155R13 radials, it is important to watch for cracking, bulges, cuts, uneven wear, and slow air loss, especially on a vehicle that may sit for extended periods.

Storage conditions matter just as much as mileage on a low-use sports car. Keeping the Europa away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition, while periodic inspection before each drive helps catch age-related problems that may not be obvious from tread depth alone.
