Lightweight, nimble, and deeply tied to Colin Chapman’s early design philosophy, the 1959 Lotus Fifteen & 7 Super sits in a very focused corner of British sports-car history. These cars are prized less for excess and more for responsiveness, simplicity, and a direct connection between chassis, road, and driver. For this exact fitment, the 1959 Lotus Fifteen & 7 Super uses a 5.15-15 bias-ply tire on a 15-inch rim, which keeps the tire decision centered on proper vintage sizing and construction. The main choice is within period-style bias-ply presentation rather than a broad range of fitment paths. That makes wheel confirmation, overall stance, and restoration intent especially important before putting the car back into regular road use.
Which Tire Size Is Right for The 1959 Lotus Fifteen & 7 Super
The 1959 Lotus Fifteen & 7 Super uses one primary tire size: 5.15-15. That is a bias-ply fitment for a 15-inch rim, and it stays consistent for the covered Base configuration. With the size already established, the real decision becomes choosing a tire that suits the car’s vintage character, intended road use, and wheel setup while preserving the proper look and fitment relationship.
A 5.15-15 size is a vintage numeric bias-ply designation in which the first number reflects the nominal section width in inches and the final number identifies a 15-inch rim. On a 1959 Lotus Fifteen & 7 Super, that sizing keeps the tire choice rooted in the type of fitment associated with lightweight British sports cars of the period. Bias-ply construction also plays a major role in the car’s visual character, sidewall shape, and traditional presentation. Selecting this size calls for close attention to wheel condition, actual rim dimensions, and clearance on any car that has been modified or restored with non-original components.
Fitment is straightforward for the covered 1959 Lotus Fifteen & 7 Super sub-model. The tire size remains consistent, so the main reason to confirm the sub-model is to make sure the car still carries the expected 15-inch wheel setup and vintage-style bias-ply fitment.

The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Owners usually reach this page to confirm the 5.15-15 fitment, understand what that vintage size means, and sort through practical questions about bias-ply construction, restoration appearance, wheel compatibility, and road-use checks on a lightweight 1959 Lotus Fifteen & 7 Super.
Tire Size & Fitment
What tire size fits a 1959 Lotus Fifteen & 7 Super?
The 1959 Lotus Fifteen & 7 Super uses a 5.15-15 tire size. This is a vintage numeric bias-ply fitment and it is the primary size associated with the covered vehicle configuration, including the Base sub-model.
That makes the key fitment task less about choosing between several sizes and more about confirming that the car still has the correct 15-inch wheel setup. On a Lotus of this era, it is also wise to check whether prior restoration work, race-oriented changes, or wheel substitutions have altered the tire and wheel relationship before selecting a replacement.
What size rim does a 1959 Lotus Fifteen & 7 Super use?
The primary tire fitment for the 1959 Lotus Fifteen & 7 Super is built around a 15-inch rim. The 5.15-15 size designation ends with 15, which corresponds to the wheel diameter used with this fitment.
Rim diameter is only part of the picture, especially on a lightweight vintage sports car. It still helps to confirm the actual wheel width and inspect the wheels themselves for age, damage, or prior modifications. A car that has seen restoration work or competition use may not still be carrying the same wheel setup it originally used.
Does the 1959 Lotus Fifteen & 7 Super Base use the same tire size?
Yes. The 1959 Lotus Fifteen & 7 Super Base uses the same 5.15-15 bias-ply tire size as the model core. That keeps fitment simple and avoids the need to sort through different primary sizes for the covered sub-model.
Even with shared fitment, it is still worth checking the car in front of you before ordering tires. Vintage Lotus cars are often restored, modified, or fitted with replacement wheels over time, so confirming the current wheel diameter, wheel width, and available clearance remains important before putting the car back into active road use.
Choosing the Right Tire
What should I consider when choosing a 5.15-15 tire for a 1959 Lotus Fifteen & 7 Super?
Start with the basics: the 1959 Lotus Fifteen & 7 Super uses a 5.15-15 bias-ply tire on a 15-inch rim. The first priority is staying with the correct size and making sure the wheel itself matches that fitment, especially on a car that may have changed hands, seen racing use, or been restored.
Beyond size, think about how the car will be used and what appearance you want to preserve. A restoration-oriented owner may focus on a traditional vintage presentation, while a road-use owner may place more emphasis on tire condition, wheel integrity, and predictable fitment. The right choice depends on the car’s actual setup rather than assumption.
How do I choose between the available 5.15-15 tires for a 1959 Lotus Fifteen & 7 Super?
The selection process begins with staying within the correct 5.15-15 size and bias-ply construction for the 1959 Lotus Fifteen & 7 Super. Once that is established, the meaningful differences usually come down to how closely the tire suits the car’s intended presentation, the condition of its wheels, and the type of use the vehicle will see.
A lightly driven collector car and a Lotus that sees regular road miles may be evaluated a little differently, even when the size is unchanged. Compare the tire’s overall vintage character with the car’s build goals, then verify wheel dimensions and clearance so the chosen tire complements the vehicle rather than simply matching the size code.
What rim-width specifications should I compare when choosing 1959 Lotus Fifteen & 7 Super tires?
Rim-width comparison matters because a 5.15-15 tire must work with the wheel that is actually on the car, not just the correct diameter. On a 1959 Lotus Fifteen & 7 Super, wheel width helps influence how the tire sits on the rim and whether the finished setup preserves appropriate clearance and visual proportion.
This is especially important on a low, narrow, lightweight sports car where wheel changes can alter the relationship between tire, fender, and steering components. Measuring the installed wheels before choosing tires helps avoid preventable fitment issues and is a smart step any time the car has been restored, modified, or fitted with non-original wheels.
Restoration & Appearance
Which tire should I choose for a period-style 1959 Lotus Fifteen & 7 Super?
For a period-style 1959 Lotus Fifteen & 7 Super, the starting point is the correct 5.15-15 bias-ply size. That keeps the car aligned with the vintage sizing and construction associated with this fitment, which matters on a Lotus where proportions, stance, and visual lightness are central to the overall presentation.
Appearance-focused owners should also consider the car’s exact restoration direction before making a final choice. A track-influenced build, a roadgoing restoration, and a preservation-minded example may call for slightly different priorities. When exact historical authenticity matters, marque-specific photos, period references, and Lotus community knowledge are valuable final checks.
Does correct tire fitment matter for a 1959 Lotus Fifteen & 7 Super restoration?
Yes, correct tire fitment matters a great deal on a 1959 Lotus Fifteen & 7 Super restoration. A small, lightweight sports car is visually sensitive to tire height, width, and sidewall shape, so using the proper 5.15-15 bias-ply format helps preserve the car’s intended stance and overall character.
Fitment also affects practicality, not just appearance. A wheel or tire choice that strays too far from the established setup can create clearance concerns or change how the tire sits within the bodywork. Checking the actual wheels, suspension condition, and the finished body fit helps the restoration look right and remain usable on the road.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1959 Lotus Fifteen & 7 Super?
Yes. Modifications can change tire fitment on a 1959 Lotus Fifteen & 7 Super even when the original tire size is 5.15-15. Aftermarket wheels, altered wheel width, suspension changes, brake conversions, or body adjustments can all affect how a vintage tire sits and whether it clears the surrounding components.
That is why the current configuration should be checked before replacing tires on any older Lotus. Confirm the installed wheel diameter and width, then inspect steering clearance, suspension travel, and fender space with the car at normal ride height. A fitment that worked years ago may no longer match the car after later changes.
What should I inspect before driving a 1959 Lotus Fifteen & 7 Super on new tires?
Before driving a 1959 Lotus Fifteen & 7 Super on new tires, inspect the wheels, valve stems, and overall mounting quality, then make sure the tires are inflated appropriately for the setup being used. It is also wise to look over the suspension, steering components, and brake hardware on a car this light and mechanically direct.
A short, careful test drive is a smart next step. Watch for rubbing, vibration, pull, or unusual steering feel, especially if the car has sat for long periods or has had recent restoration work. Rechecking tire pressure and a quick visual inspection after the first drive can catch problems before they become larger issues.
How should 5.15-15 tires on a collector 1959 Lotus Fifteen & 7 Super be maintained?
Collector-car maintenance for 5.15-15 tires starts with regular inspection rather than mileage alone. On a 1959 Lotus Fifteen & 7 Super, look for sidewall cracking, tread separation, bulges, cuts, flat spotting, and slow air loss, since low-use vintage cars can age their tires long before they wear them out.
Storage conditions matter almost as much as road use. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires between drives. Pressure checks should be part of every outing, and any tire that shows age-related deterioration deserves close evaluation before the car returns to normal road service.
