The 1978 Lancia Beta belongs to the period when European cars were blending sharp, modern styling with everyday road manners, and the Beta stood out for doing that in coupe, sedan, HPE, and spider form. Its front-wheel-drive layout and distinctly Italian character make tire choice especially important to the way the car looks and feels on the road. The 1978 Lancia Beta uses a 175/70R14 radial tire on a 14-inch rim. That keeps the decision focused less on size changes and more on selecting the right radial in the proper format, including details like sidewall appearance. For a restoration-minded driver, the key is balancing period-style presentation with sound road-use fitment.
Which Tire Size Is Right for The 1978 Lancia Beta
The 1978 Lancia Beta uses one primary tire size: 175/70R14, a radial tire fitted to a 14-inch rim. That same size carries across the covered 2000 Coupe, 2000 Sedan & HPE, and 2000 Spider models, so the main decision is not which size fits, but which tire style and product details best suit the car's intended appearance and use.
Fit(s): 2000 Coupe, 2000 Sedan & HPE, and 2000 Spider
Construction: Radial|Rim: 14 in
The 175/70R14 size is a metric radial format: 175 refers to nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On the 1978 Lancia Beta, this is the standard fitment format and keeps the car in a modern radial sizing convention rather than an older bias-ply system. Available choices in this size include a Travelstar UN106 with a narrow whitewall sidewall treatment. That makes this size especially useful for owners who want to stay with the correct dimensions while still choosing an appearance that complements a restoration or driver-grade car.
Tire fitment is straightforward across the covered 1978 Lancia Beta sub-models, with each one using the same 175/70R14 radial size. Even so, checking the exact sub-model is still worthwhile when confirming the car's current wheel setup and overall restoration direction.

1978 Lancia Beta 2000 Coupe
The 1978 Lancia Beta 2000 Coupe uses the same 175/70R14 radial fitment as the other covered Beta variants. That keeps tire selection centered on staying with the proper metric radial size and choosing the sidewall presentation that best matches the coupe's intended look.
The 1978 Lancia Beta 2000 Sedan & HPE also uses 175/70R14 radial tires, so there is no separate primary size to sort through. The practical decision is choosing a tire in the correct dimensions while confirming that the car still retains the expected 14-inch wheel setup.
The 1978 Lancia Beta 2000 Spider shares the 175/70R14 radial size used across the covered range. That means owners can focus on correct sizing, radial construction, and the visual character of the tire rather than sorting through multiple primary fitments.
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.

These 1978 Lancia Beta tire FAQs focus on the car's 175/70R14 radial fitment, 14-inch rim compatibility, product selection, restoration-minded appearance choices, and the basic checks worth making before putting a classic Beta back on the road.
Tire Size & Fitment
What tire size fits a 1978 Lancia Beta?
The 1978 Lancia Beta uses a 175/70R14 radial tire. That size applies across the covered Beta 2000 Coupe, 2000 Sedan & HPE, and 2000 Spider models, so the primary fitment question is unusually straightforward for this year and model.
That consistency makes tire selection easier, but it is still smart to confirm the actual wheel setup on the car before replacing tires. A Beta that has been modified over the years may have different wheels than expected, and checking the current rim diameter, wheel width, and clearance helps keep the new tires aligned with the car's present configuration.
What size rim does a 1978 Lancia Beta use?
The 1978 Lancia Beta tire fitment centers on a 14-inch rim, paired with the 175/70R14 radial size. The 14 at the end of the tire size is the rim diameter in inches, which is the wheel diameter the tire is built to mount on.
Rim diameter is the first measurement to verify before ordering replacement tires, because a 14-inch tire cannot be mounted on a different wheel diameter. It also helps to inspect the wheel width and the condition of the wheels themselves, especially on a collector car that may have seen wheel swaps, refinishing work, or years of intermittent use.
Do all 1978 Lancia Beta sub-models use the same tire size?
The covered 1978 Lancia Beta sub-models all use the same primary tire size: 175/70R14. That includes the 2000 Coupe, the 2000 Sedan & HPE, and the 2000 Spider, all in radial construction.
Shared size across the sub-model range simplifies replacement, but it does not remove the need to inspect the individual car. A Beta that has been altered with aftermarket wheels, suspension changes, or body modifications may need closer checking for tire clearance and wheel compatibility, even when the original fitment is the same across the model family.
Choosing the Right Tire
What should I consider when choosing a 175/70R14 tire for a 1978 Lancia Beta?
Start with the correct 175/70R14 size and radial construction, since that is the primary fitment for the 1978 Lancia Beta. From there, the meaningful differences are product character and appearance details, including tire series and whether the sidewall treatment suits a more understated driver or a restoration-minded presentation.
Wheel compatibility still matters, even when the nominal size is correct. Compare the tire against the car's actual wheel setup, and think about how the car will be used, whether that means occasional show use, local driving, or regular road miles. On a classic Beta, visual presentation and proper fitment usually matter just as much as the raw size designation.
What sidewall styles are available for 1978 Lancia Beta tires?
A narrow whitewall sidewall style is available in 175/70R14 for the 1978 Lancia Beta. That gives the car a more traditional visual accent than a plain blackwall, while still staying within the correct tire size and radial construction used for this application.
Sidewall choice is mostly an appearance decision, but it can strongly affect how the car presents. A narrow whitewall can complement a restoration-oriented Beta or add a period-flavored look to a driver, while owners aiming for a more restrained European appearance may want to compare that visual treatment carefully against the car's trim, paint, and overall finish.
What brands offer tires for the 1978 Lancia Beta?
Travelstar offers a 175/70R14 radial tire for the 1978 Lancia Beta. The available example in this fitment is the UN106 series, which combines the correct metric radial sizing with a narrow whitewall presentation.
For a single-size application like the Beta, brand comparison is less about sorting through many fitments and more about matching the available tire to the car's needs. Look closely at the tire series, sidewall style, and basic wheel compatibility, then decide whether the goal is a cleaner road-going presentation, a more restoration-minded look, or a practical replacement in the proper size.
Restoration & Appearance
Which tire should I choose for a period-style 1978 Lancia Beta?
A period-style approach for a 1978 Lancia Beta starts with the correct 175/70R14 radial size on a 14-inch rim. Keeping the proper size and radial construction preserves the car's intended stance and sizing relationship better than drifting into a different fitment without carefully checking the results.
Appearance then becomes the deciding factor. A narrow whitewall can give the Beta a more vintage visual character, but exact originality is a separate question and should be checked against marque-specific references if that level of accuracy matters. For most restoration-oriented owners, the goal is a tire that looks appropriate on the car while still respecting its original sizing format.
Does correct tire fitment matter for a 1978 Lancia Beta restoration?
Correct tire fitment matters a great deal on a 1978 Lancia Beta restoration because tire size has a direct effect on stance, wheelwell fill, and overall visual balance. Staying with the proper 175/70R14 radial format helps the car retain the proportional look associated with this Beta application.
Restoration decisions are not only cosmetic, though. A mismatched tire size can create unnecessary clearance questions and can make the car look visually off even before it is driven. Owners chasing a highly accurate presentation should verify wheel and tire details against trusted Lancia references, while driver-level restorations should still keep sizing and rim compatibility at the center of the decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1978 Lancia Beta?
Yes, modifications can affect tire fitment on a 1978 Lancia Beta even when the original tire size is 175/70R14. Changes such as aftermarket wheels, altered wheel offset, suspension lowering, spring replacement, or bodywork changes can all influence how much room the tire has during steering and suspension movement.
A Beta that no longer sits on its original-style wheels should be checked carefully before new tires are installed. Measure the current wheel diameter and width, then look at inner and outer clearance at full steering lock and under compression. That extra inspection is especially important on older cars, where decades of owner changes can leave the current setup quite different from stock.
What should I inspect before driving a 1978 Lancia Beta on new tires?
Before driving a 1978 Lancia Beta on new tires, inspect the wheels, valve stems, lug hardware, and overall tire mounting condition. It is also wise to check inflation, confirm that the tires clear the body and suspension, and make sure the steering turns freely without rubbing from lock to lock.
On a collector-era car, the surrounding chassis deserves attention too. Brake condition, wheel bearings, alignment, and suspension wear can affect how a fresh set of tires behaves on the road. A careful once-over helps the new 175/70R14 tires perform as intended and reduces the chance that an old mechanical issue will be mistaken for a tire problem.
How should 175/70R14 tires on a collector 1978 Lancia Beta be maintained?
175/70R14 tires on a collector 1978 Lancia Beta should be maintained with regular pressure checks, visual inspections, and periodic attention even when the car is not driven often. Look for cracking, bulges, cuts, tread irregularity, and signs of slow air loss, since stored classics can age tires without accumulating many miles.
Storage conditions matter just as much as mileage on an occasional-use Beta. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition, and moving the vehicle periodically can reduce long-term stress in one contact area. Before any longer drive, inspect the tires again and confirm that age and condition still support safe road use.
