The 1977 Lancia Beta came from an era when Italian sporting cars and coupes balanced sharp road manners with everyday practicality, and the Beta range brought that character to the coupe, sedan, HPE, and spider body styles. For this exact year, make, and model, the primary fitment centers on a 175/70R14 radial tire on a 14-inch rim. That makes the decision less about sorting through multiple factory-size paths and more about choosing the right presentation within the correct fitment. A narrow whitewall radial is available in this size, giving the car a more distinctive vintage touring look. Before making a final choice, it still pays to confirm the actual wheels on the car and match the tire to restoration goals and intended road use.
Which Tire Size Is Right for The 1977 Lancia Beta
The 1977 Lancia Beta uses one primary tire size: 175/70R14 radial on a 14-inch rim. That same size carries across the covered Beta 2000 Coupe, Beta 2000 Sedan & HPE, and Beta 2000 Spider models, so the main decision is choosing the tire style that suits the car's appearance and use rather than sorting through multiple original fitments.
Fit(s): 2000 Coupe, 2000 Sedan & HPE, and 2000 Spider
Construction: Radial|Rim: 14 in
A 175/70R14 size uses a 175-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 14-inch rim diameter. On the 1977 Lancia Beta, this is a modern metric radial fitment that matches the car's late-1970s tire sizing convention rather than an older bias-ply format. Available choices in this size include a Travelstar UN106 radial with a narrow whitewall sidewall treatment, which adds a more traditional touring appearance than a plain black sidewall. Choosing this size keeps the fitment centered on the Beta's intended wheel diameter while letting appearance and driving use guide the final tire selection.
Tire fitment is straightforward across the covered 1977 Lancia Beta sub-models because each one uses the same 175/70R14 radial size. Checking the exact sub-model still helps confirm that the car has not been altered with different wheels or a non-stock suspension setup over the years.

1977 Lancia Beta 2000 Coupe
The 1977 Lancia Beta 2000 Coupe uses the same 175/70R14 radial fitment found across the covered Beta range. That keeps tire selection focused on choosing the right radial style and confirming the coupe still wears the proper 14-inch wheels before installation.
The 1977 Lancia Beta 2000 Sedan & HPE also uses 175/70R14 radial tires. For this sub-model grouping, the practical choice is deciding whether a more traditional narrow whitewall look suits the car while verifying the wheels and overall stance match the intended fitment.
The 1977 Lancia Beta 2000 Spider stays with the same 175/70R14 radial size as the other covered versions. That means the buying decision centers on tire presentation and general road use, along with a quick check that the spider still has the correct 14-inch wheel setup.
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.

Tire Size & Fitment
What tire size fits a 1977 Lancia Beta?
The 1977 Lancia Beta uses a 175/70R14 radial tire. That size applies across the covered Beta 2000 Coupe, Beta 2000 Sedan & HPE, and Beta 2000 Spider sub-models, making fitment more consistent than on many older collector cars that changed sizes by trim or package.
Using the correct size keeps the tire matched to the car's intended 14-inch wheel diameter and overall proportions. It is still smart to check the actual wheels on the car before ordering, especially if the Beta has been updated over the years with aftermarket rims, suspension changes, or a different stance than stock.
What size rim does a 1977 Lancia Beta use?
The 1977 Lancia Beta tire fitment is built around a 14-inch rim. The primary tire size, 175/70R14, is a radial size designed for that wheel diameter, so the final number in the tire code and the wheel itself need to match.
Rim diameter is the first thing to confirm because a 14-inch tire cannot be mounted on a wheel of another diameter. A quick wheel check matters even on a car with a known factory-style setup, since many classic imports have had wheel swaps over time that can change tire selection completely.
Do all 1977 Lancia Beta sub-models use the same tire size?
Yes. The covered 1977 Lancia Beta sub-models all use the same 175/70R14 radial size, including the 2000 Coupe, 2000 Sedan & HPE, and 2000 Spider. That shared fitment simplifies the search because the size itself does not change from one of these Beta variants to another.
Even with shared sizing, condition and configuration still matter. A restored coupe, a spider on replacement wheels, or an HPE with altered ride height can need a closer look at wheel width and clearance before mounting tires, so it helps to confirm the car's present-day setup rather than assuming every example remains unchanged.
Choosing the Right Tire
What should I consider when choosing a 175/70R14 tire for a 1977 Lancia Beta?
Start with the basics: correct size, radial construction, and a true 14-inch wheel match. From there, the choice becomes more about how the tire suits the car's use and appearance, since the 1977 Lancia Beta does not require sorting between multiple primary factory sizes in this fitment range.
A buyer should compare sidewall presentation, overall visual character, and whether the car is being preserved as a stock-looking road car or driven with a more personalized style. It also helps to inspect wheel condition and confirm that the tire selected matches the Beta's actual setup if the car has seen wheel or suspension changes.
What sidewall styles are available for 1977 Lancia Beta tires?
The available 175/70R14 option for the 1977 Lancia Beta uses a narrow whitewall sidewall style. That gives the tire a more vintage touring look than a plain black sidewall and can change the car's visual character without changing the underlying size or radial construction.
Sidewall style is mostly an appearance decision, but it matters on a car with clean late-1970s lines like the Beta. A narrow whitewall can complement a restoration-oriented presentation, while buyers pursuing a different look may want to compare how the tire's sidewall treatment works with the car's paint, trim, and wheel design.
What brands offer tires for the 1977 Lancia Beta?
The currently available tire choice in 175/70R14 for the 1977 Lancia Beta is from Travelstar. It is offered as a radial tire in the UN106 series, giving Beta owners a correct-size option that stays within the car's proper wheel diameter and sizing format.
Brand is only one part of the decision, especially when the fitment itself is straightforward. It still makes sense to compare the tire's sidewall appearance, confirm that the wheel and suspension setup remain compatible, and choose a tire that matches whether the car is being maintained as a roadgoing classic or shown with a more period-style presentation.
Restoration & Appearance
Which tire should I choose for a period-style 1977 Lancia Beta?
A period-style approach starts with the correct 175/70R14 radial size because that preserves the Beta's intended late-1970s fitment format and 14-inch wheel relationship. Within that size, a narrow whitewall radial offers a more traditional visual presentation than a plain contemporary-looking sidewall.
Appearance choices should still be made carefully on a restoration-minded car. If exact originality matters, compare the tire's visual treatment with marque references, surviving photos, or model-specific historical guidance, since a tire can be size-correct and still reflect a more restoration-oriented style rather than a proven factory-delivered appearance.
Does correct tire fitment matter for a 1977 Lancia Beta restoration?
Yes, correct tire fitment matters because tire size has a strong effect on the stance, wheel-to-body proportion, and overall presentation of a restored 1977 Lancia Beta. Staying with the proper 175/70R14 radial size helps keep the car visually balanced and consistent with its era.
A tire that is too tall, too short, or mounted on the wrong wheel diameter can quickly make a careful restoration look out of place. Beyond appearance, it is worth confirming wheel condition, suspension height, and clearance so the finished car not only looks right for its period but is also ready for regular road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1977 Lancia Beta?
Yes, modifications can affect tire fitment on a 1977 Lancia Beta even though the original fitment is straightforward. Wheel changes, altered offsets, lowering, replacement springs, or bodywork differences can all change how a 175/70R14 tire sits in the wheel opening and how much clearance it has in actual use.
That matters most on older enthusiast cars that may have passed through several owners. A quick inspection of wheel diameter, wheel width, steering clearance, and fender space before mounting new tires helps prevent surprises and confirms that the car's current setup still supports the intended size safely and cleanly.
What should I inspect before driving a 1977 Lancia Beta on new tires?
Inspect the wheels, valve stems, lug hardware, and the general condition of the suspension and steering before putting a 1977 Lancia Beta back on the road with new tires. It also helps to verify tire pressure, check for even mounting clearance, and make sure nothing contacts the tire at full steering lock.
A fresh set of tires cannot compensate for worn components or an incorrect wheel setup. Looking over alignment-related wear, wheel bearing play, brake drag, and any signs of rubbing gives a clearer picture of whether the car is ready for regular use, especially if it has been parked, restored, or driven only occasionally.
How should 175/70R14 tires on a collector 1977 Lancia Beta be maintained?
Collector-car tires should be maintained with regular pressure checks, periodic visual inspection, and clean storage conditions. On a 1977 Lancia Beta, that means watching the 175/70R14 tires for cracking, bulges, cuts, uneven tread wear, or slow air loss, particularly if the car spends long periods parked between drives.
Low annual mileage can hide age and condition issues, so tread depth alone is not enough. The car benefits from being stored away from prolonged sunlight, moisture, and ozone sources, and it is wise to inspect the tires before every outing so the Beta is not relying on rubber that looks acceptable at a glance but has aged in place.
