The 1976 Fiat 131 came from an era when compact European sedans and wagons balanced practical packaging with crisp road manners, and the 131 earned a following for exactly that blend. For owners preserving a Brava sedan or wagon today, tire choice is less about chasing oversized modern fitments and more about staying true to the car’s 13-inch radial setup. The 1976 Fiat 131 uses 160R13 and 165R13 radial sizes, so the key decision is confirming which of those two applies to your car. Available choices center on blackwall radial options, brand preference, and whether a restoration-minded or road-use-focused presentation matters most.
Which Tire Size Is Right for The 1976 Fiat 131
The 1976 Fiat 131 uses two primary tire sizes, both in radial construction on 13-inch rims. Because the Sedan (Brava) and Wagon (Brava) can use either 160R13 or 165R13, the first step is confirming the exact wheel and tire setup on the car before choosing a replacement. Once size is verified, the decision shifts to brand, tire series, and how closely you want to stay with a traditional Euro-style radial presentation.
160R13 is a Euro-metric radial size in which 160 refers to the nominal section width in millimeters, R indicates radial construction, and 13 is the rim diameter in inches. On a 1976 Fiat 131, this size reflects the traditional narrow-profile radial look common to compact European cars of the period. It suits buyers who want to preserve the car’s light, original-style tire proportions and should be matched carefully to the wheel actually installed on the vehicle. Checking current wheel width and existing tire clearance is especially important before settling on this narrower fitment.
165R13 is also a Euro-metric radial size, with 165 indicating nominal section width in millimeters, radial construction marked by the R, and a 13-inch rim requirement. For the 1976 Fiat 131, it represents a slightly wider period-style radial option within the same basic sizing family. Available choices include Michelin and Dunlop blackwall tires in series such as XAS-FF, XAS, and SP Sport Aquajet, giving buyers some variation in brand and tread-era character. This size is worth evaluating when the car already wears 165R13 tires or the wheel setup favors that fitment.
Tire fitment for the covered 1976 Fiat 131 sub-models is straightforward in one sense and still worth verifying in another. Both the Sedan (Brava) and Wagon (Brava) use the same two radial size families, so the real job is confirming which of the two is on your specific car.

1976 Fiat 131 Sedan (Brava)
The 1976 Fiat 131 Sedan (Brava) uses either 160R13 or 165R13 in radial construction. That means tire selection starts with confirming the sedan’s present wheel and size setup, then choosing the replacement that best matches your intended road use and traditional appearance goals.
The 1976 Fiat 131 Wagon (Brava) also uses 160R13 or 165R13 radial tires. For wagon owners, the important step is making sure the current wheels and tire size agree before comparing available blackwall radial options in the correct 13-inch 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.

Available 165R13 choices focus on blackwall radials from Michelin and Dunlop. The product grid is most useful for comparing tire series such as Michelin XAS-FF, Michelin XAS, and Dunlop SP Sport Aquajet, along with rim-width compatibility and other specification details.
These FAQs for the 1976 Fiat 131 focus on the two primary radial sizes, 13-inch rim fitment, product selection, restoration-minded appearance, and the basic checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 1976 Fiat 131?
The 1976 Fiat 131 uses two primary tire sizes: 160R13 and 165R13. Both are radial tire sizes designed for 13-inch rims, and both appear across the covered Fiat 131 Sedan (Brava) and Wagon (Brava) sub-models.
That makes size confirmation more important than simply ordering by year and model alone. Checking the tire already on the car, verifying the wheel size, and confirming that the current setup has proper clearance will help determine whether your Fiat 131 should stay with 160R13 or 165R13.
What size rim does a 1976 Fiat 131 use?
The 1976 Fiat 131 uses a 13-inch rim diameter with its primary tire fitments. Both 160R13 and 165R13 are built for 13-inch wheels, so the rim diameter remains consistent even though the tire width changes slightly between the two sizes.
Rim diameter is only part of the fitment picture, especially on an older car that may have had wheels changed over time. It is wise to confirm the actual wheel width and current tire size on the car before choosing between the two radial options, since width compatibility can affect how the tire sits and performs.
Do all 1976 Fiat 131 sub-models use the same tire size?
The covered 1976 Fiat 131 sub-models share the same tire-size range rather than one single exclusive size. Both the Sedan (Brava) and Wagon (Brava) can use 160R13 or 165R13 radial tires on 13-inch rims.
That means sub-model identification alone does not settle the question the way it does on some vehicles. The better approach is to confirm the exact wheel-and-tire setup already on your sedan or wagon, then choose the correct replacement size within that shared fitment range.
Choosing the Right Tire
What should I consider when choosing a 165R13 tire for a 1976 Fiat 131?
Start with the basics: confirm that 165R13 is the size currently suited to your 1976 Fiat 131 and that the car is still running the correct 13-inch wheel setup. For this size, available choices include blackwall radial tires from Michelin and Dunlop in series such as XAS-FF, XAS, and SP Sport Aquajet.
After size is confirmed, compare the tire’s overall character rather than looking for one universal answer. Buyers often weigh brand preference, period-style appearance, rim-width compatibility, and how the car will be used, whether that means occasional collector driving, regular fair-weather road use, or a more restoration-oriented presentation.
What sidewall styles are available for 1976 Fiat 131 tires?
The available 165R13 product choices for the 1976 Fiat 131 use a blackwall sidewall style. That keeps the presentation faithful to the clean, understated look most buyers expect from a compact European car of the mid-1970s.
Sidewall appearance matters because it strongly influences how the car sits visually, especially on a sedan or wagon with relatively modest wheel diameter. If maintaining a traditional road-car look is important, a blackwall radial preserves that character without drawing attention away from the Fiat 131’s original proportions.
What brands offer tires for the 1976 Fiat 131?
For the 165R13 fitment used on the 1976 Fiat 131, available tire choices include Michelin and Dunlop. Michelin appears in the XAS-FF and XAS series, while Dunlop is represented by the SP Sport Aquajet, all in radial construction and blackwall form.
Brand selection should be treated as one part of the decision, not the whole decision. Once the correct size is confirmed, it helps to compare each tire’s series, intended visual character, and wheel compatibility so the final choice suits both the way the car looks and the way it will be driven.
Restoration & Appearance
Which tire should I choose for a period-style 1976 Fiat 131?
A period-style approach for a 1976 Fiat 131 starts by staying with one of the correct primary radial sizes, 160R13 or 165R13, on a 13-inch rim. That preserves the car’s proper tire profile and avoids pushing the Fiat 131 toward an oversized or overly modern appearance.
From there, the visual choice is mostly about maintaining a traditional Euro-car presentation. A blackwall radial in the correct size generally suits that goal well, but buyers pursuing stricter originality should also compare the car against marque references, period photos, and restoration documentation before settling on a final tire series.
Does correct tire fitment matter for a 1976 Fiat 131 restoration?
Correct tire fitment matters a great deal on a 1976 Fiat 131 restoration because these cars rely on relatively small-diameter wheels and narrow radial proportions to look right. Moving away from 160R13 or 165R13 can change the stance and visual balance even before the car turns a wheel.
Fitment also affects how authentic the finished restoration feels in use. Keeping the proper 13-inch radial format helps preserve the Fiat’s period character, while careful confirmation of wheel size and tire width helps avoid rubbing, odd proportions, or a look that seems noticeably out of step with the car’s era.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1976 Fiat 131?
Yes, modifications can affect tire fitment on a 1976 Fiat 131 even when the replacement tire is one of the correct primary sizes. Wheel changes, altered ride height, suspension work, or body modifications can all influence how a 160R13 or 165R13 tire sits within the available space.
A Fiat 131 with aftermarket wheels should have its actual wheel diameter and width checked before any tire is chosen. Clearance at the fenders, steering range, and suspension travel are worth verifying as well, since an older car may no longer match the setup it had when it originally left service decades ago.
What should I inspect before driving a 1976 Fiat 131 on new tires?
Before putting a 1976 Fiat 131 back on the road with new tires, inspect the wheels, valve stems, and overall condition of the suspension and steering components. It also helps to make sure the chosen tire size matches the car’s current setup and that there is no obvious interference at full steering lock.
A careful pre-drive check should also include tire pressure, lug fastener security, and a quick look for any uneven stance that might point to alignment or suspension issues. On a collector-era Fiat, a short local test drive followed by a second inspection is a smart way to confirm that everything has settled properly.
How should 160R13 or 165R13 tires on a collector 1976 Fiat 131 be maintained?
Tires on a collector 1976 Fiat 131 should be maintained with regular pressure checks, visual inspections, and sensible storage habits. Whether the car uses 160R13 or 165R13, pay attention to tread wear, sidewall cracking, cuts, bulges, and any sign of slow air loss before routine driving.
Low-mileage classics often age out their tires before they wear them out, so time and storage conditions matter as much as mileage. Keeping the Fiat 131 away from prolonged sun, heat, moisture, and ozone sources can help preserve the tires, and any questionable condition should be evaluated before longer trips.
