The 1984 Renault R18i came from a period when practical European sedans and wagons were defined by efficiency, road manners, and compact packaging rather than excess. In U.S.-market collector circles, the R18i stands apart as a distinctive front-wheel-drive Renault with a very different character from domestic cars of the same era. Tire choice centers on two 13-inch radial sizes, 155R13 and 185/70R13, so the key question is matching the car’s actual wheel and setup. Available options range from traditional blackwall European-style radials to redline and wide whitewall treatments in 185/70R13. That makes fitment, appearance, and intended use just as important as simply matching the rim diameter.
Which Tire Size Is Right for The 1984 Renault R18i
The 1984 Renault R18i uses two primary tire sizes, both built as radials on 13-inch rims. The first step is confirming which wheel and vehicle setup you have, because 155R13 and 185/70R13 differ in size format and section width even though they share the same rim diameter. Once that is settled, the real choice becomes appearance, brand, and the type of driving or restoration presentation you want.
155R13 is a Euro-metric radial size in which 155 refers to nominal section width in millimeters, R indicates radial construction, and 13 identifies the wheel diameter in inches. This format is commonly associated with an approximately 80-series profile and suits the R18i’s compact European tire sizing character. Available choices include Michelin and Dunlop in blackwall form, with series such as Michelin XAS-FF and SP Sport Aquajet. This size makes the most sense when you want a narrower, traditional European-style fitment and need to confirm compatibility with the car’s actual wheel width.
185/70R13 is a metric radial size where 185 is the nominal section width in millimeters, 70 is the aspect ratio, R marks radial construction, and 13 is the wheel diameter. On a 1984 Renault R18i, it represents a broader modern metric format than 155R13 while staying on the same 13-inch rim. Product choices are much wider here, including BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, with blackwall, redline, and wide whitewall sidewall treatments. It is the size to evaluate carefully if appearance options and product variety matter as much as basic fitment.
Sub-model fitment is straightforward here, because the covered Renault R18i sub-model uses the same two 13-inch radial tire sizes. Checking the exact sub-model still matters so the tire choice stays aligned with the wheel setup and the style of replacement you want.

Tire Size & Fitment
What tire size fits a 1984 Renault R18i?
The 1984 Renault R18i uses two primary tire sizes: 155R13 and 185/70R13. Both are radial tires designed for 13-inch wheels, so the basic fitment question is not bias-ply versus radial, but which of these two radial sizes matches the car’s actual wheel and setup.
A buyer should confirm more than the wheel diameter before choosing between them. The two sizes use different sizing conventions and differ in section width, so wheel width, clearance, and the car’s current configuration should all be checked, especially if the Renault has been fitted with replacement wheels or other changes over the years.
What size rim does a 1984 Renault R18i use?
Both primary tire sizes used on the 1984 Renault R18i are built for 13-inch rims. That applies to 155R13 and 185/70R13, so the wheel diameter remains consistent even though the tire formats are different.
Rim diameter is only the first step in a sound fitment decision. Wheel width still matters, particularly because available products within these sizes call for different rim-width ranges, and that can affect whether a specific tire is appropriate for the wheel already on the car.
Does the 1984 Renault R18i Sportwagon use the same tire size?
Yes. The 1984 Renault R18i Sportwagon uses the same two primary radial tire sizes associated with this application: 155R13 and 185/70R13. Both are intended for 13-inch rims, so the Sportwagon follows the same overall fitment pattern.
That does not mean every tire choice should be made only by size code. The practical decision is whether the wagon is on the narrower Euro-metric type of fitment or the wider 185/70R13 setup, then selecting a tire that matches the wheel width, desired appearance, and the way the vehicle will actually be used.
Choosing the Right Tire
What should I consider when choosing a tire for a 1984 Renault R18i?
Start with the correct primary size for the car: 155R13 or 185/70R13, both on 13-inch rims. After that, compare the tire’s sizing format, wheel-width compatibility where stated, brand, sidewall treatment, and the overall look you want from a period European blackwall to a more stylized redline or wide whitewall presentation.
Intended use matters just as much as appearance. A lightly driven collector car may call for a different choice than a Renault that sees regular road miles, and any vehicle with aftermarket wheels or suspension changes deserves an extra clearance and wheel-spec check before a final decision is made.
What sidewall styles are available for 1984 Renault R18i tires?
Blackwall is the most common sidewall style offered for the 1984 Renault R18i, appearing in both 155R13 and 185/70R13 selections. In 185/70R13, there are also redline and wide whitewall options, giving the car a broader range of visual treatments than a basic blackwall-only fitment.
The right sidewall style depends on the presentation you want from the car. Blackwall usually preserves a more understated European look, while redline or wide whitewall can create a more customized or restoration-oriented appearance, so the decision should follow the car’s styling direction rather than size alone.
What brands offer tires for the 1984 Renault R18i?
Tires for the 1984 Renault R18i are available from Michelin, Dunlop, BFGoodrich, Avon, and Vredestein. Brand availability depends on the tire size, with 155R13 offered in a smaller European-style selection and 185/70R13 carrying a wider mix of brands and tire series.
The best way to use that brand variety is to compare how each option aligns with the car’s needs. Some buyers focus on traditional blackwall European character, while others are more interested in sidewall appearance choices or matching a specific wheel-width range within the selected size.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Renault R18i?
A period-style 1984 Renault R18i usually starts with the correct 13-inch radial size already associated with the car, then narrows the choice by visual character. The 155R13 format has a distinctly traditional European feel, while 185/70R13 opens the door to a broader mix of classic-looking radial products.
Appearance should still be balanced against the car’s actual wheel setup and intended use. For a restoration where exact originality matters, marque-specific references and historical photos are worth consulting, since a period-style tire can look appropriate without automatically being the exact tire style delivered when the car was new.
How does tire construction affect the appearance of a restored 1984 Renault R18i?
Construction is simple on the 1984 Renault R18i because both primary fitments are radial, so the appearance difference comes more from tire format and sidewall treatment than from choosing between bias-ply and radial. A narrow 155R13 blackwall presents differently than a wider 185/70R13 with redline or wide whitewall styling.
That means restoration appearance is shaped by proportion as much as decoration. Tire width, profile, and sidewall presentation all affect how the Renault sits visually, so it is worth comparing the look you want at the car itself before settling on a tire simply because it shares the correct 13-inch rim diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Renault R18i?
Yes. Even though the 1984 Renault R18i uses 13-inch radial tire sizes, modifications can change whether a particular tire is still appropriate. Aftermarket wheels, different wheel widths, suspension changes, lowering, or body alterations can all affect clearance and the way either 155R13 or 185/70R13 sits on the car.
A modified car should be checked at the wheel rather than by size code alone. Verifying wheel width, steering clearance, and space at the fender and suspension helps prevent choosing a tire that is technically the right diameter but mismatched to the Renault’s current setup.
What should I inspect before driving a 1984 Renault R18i on new tires?
Before putting a 1984 Renault R18i back on the road with new tires, inspect the wheels, valve stems, lug hardware, and basic clearance at full steering lock. It is also wise to confirm that the mounted tire size matches the car’s intended setup and that inflation is set appropriately for the tire in use.
The vehicle itself deserves attention too, especially on a low-use collector car. Check for worn suspension parts, brake drag, uneven alignment behavior, and any sign that the previous tires rubbed or wore irregularly, because those issues can shorten the life of a fresh set very quickly.
How often should tires on a 1984 Renault R18i be inspected?
Tires on a 1984 Renault R18i should be inspected regularly, not just by mileage. A car that is driven infrequently can age its tires in storage, so tread condition, sidewall cracking, bulges, cuts, and air loss deserve routine attention even when the Renault does not see many miles.
A quick check before each outing and a more careful inspection at regular intervals is a sensible approach for an older vehicle. Storage conditions matter as well, since prolonged exposure to sunlight, heat, moisture, and ozone sources can shorten tire life even when the car spends much of its time parked.
