The 1983 Renault R18i reflects the practical European front-wheel-drive family-car thinking that defined many imported sedans and wagons of the era. Its appeal today often comes from that blend of everyday usability, distinctive French character, and the challenge of keeping a less-common collector car on the road with the right details. Tire selection for the 1983 Renault R18i centers on two 13-inch radial sizes, 155R13 and 175/70R13. That creates a clear choice between a traditional Euro-metric radial look and a lower-profile metric radial alternative, with blackwall offerings from Michelin, Dunlop, and Avon. The key is matching the car's actual wheel setup and the owner's originality or road-use priorities.
Which Tire Size Is Right for The 1983 Renault R18i
The 1983 Renault R18i uses two primary tire sizes, and both are radial tires for 13-inch wheels. Because the Deluxe Sedan and Deluxe Wagon can use either size, the first step is confirming which size is on the car now and whether the wheels remain stock in width and overall setup before comparing appearance, profile, and available tire choices.
155R13 is a Euro-metric radial size in which 155 refers to the nominal section width in millimeters, R indicates radial construction, and 13 identifies the wheel diameter in inches. In this format, the aspect ratio is not stated, and it is commonly understood as a taller-profile Euro-metric radial style. For the 1983 Renault R18i, this size supports a more traditional imported-car presentation and is available in blackwall form from Michelin and Dunlop through the Michelin XAS-FF and SP Sport Aquajet series. It is the size to evaluate when preserving a period-style look matters as much as maintaining proper 13-inch fitment.
175/70R13 is a metric radial size with a 175-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 13-inch rim diameter. Compared with older Euro-metric sizing conventions, this format gives a more modern size expression and a lower-profile profile than an unstated-aspect-ratio 155R13. For the 1983 Renault R18i, this size is available as a blackwall Avon CR6ZZ, giving the buyer a distinct series choice within the correct 13-inch radial fitment. It is worth considering when the car already runs this size or when wheel width and overall clearance have been checked carefully.
Tire fitment is straightforward across the covered 1983 Renault R18i sub-models because both the Deluxe Sedan and Deluxe Wagon can use the same two radial sizes. Even so, checking the exact sub-model and the wheel setup still helps confirm whether the car is staying with 155R13 or 175/70R13.

1983 Renault R18i Deluxe Sedan
The 1983 Renault R18i Deluxe Sedan can use either 155R13 or 175/70R13, both in radial construction on 13-inch wheels. That gives the sedan owner a choice between a taller Euro-metric style and a lower-profile metric radial, with the final decision tied to the wheels on the car and the desired appearance.
The 1983 Renault R18i Deluxe Wagon also uses 155R13 or 175/70R13 radial tires on 13-inch rims. For wagon owners, the main selection point is confirming which size suits the existing wheel width and overall setup before choosing among the available blackwall tire series.
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.
Best 1983 Renault R18i Tires for Sale
Available 1983 Renault R18i tire choices center on blackwall radial options in 155R13 and 175/70R13. Buyers can compare Michelin, Dunlop, and Avon offerings by tire series, sizing format, and rim-width compatibility where that specification is stated.
Common 1983 Renault R18i tire questions usually come down to choosing between 155R13 and 175/70R13, confirming 13-inch wheel fitment, and deciding which radial tire series best suits the car's appearance and road use.
Tire Size & Fitment
What tire size fits a 1983 Renault R18i?
The 1983 Renault R18i uses two primary tire sizes: 155R13 and 175/70R13. Both are radial tires built for 13-inch wheels, and both appear across the covered Deluxe Sedan and Deluxe Wagon configurations rather than being limited to one body style alone.
That means the real fitment question is not simply whether a tire fits a Renault R18i, but which of those two sizes matches the wheels and overall setup on the car. Checking the current tire size, wheel width, and any past changes to wheels or suspension will help narrow the right choice before comparing brands or tire series.
What size rim does a 1983 Renault R18i use?
The 1983 Renault R18i uses a 13-inch rim diameter with both of its primary tire sizes. The two applicable radial sizes, 155R13 and 175/70R13, are both built around that same 13-inch wheel diameter rather than requiring different diameter wheels.
Rim diameter is only part of the fitment picture, so it helps to confirm wheel width as well before selecting a tire. Some available 155R13 and 175/70R13 products include stated rim-width ranges, and that can matter when comparing a traditional Euro-metric radial with a wider, lower-profile metric radial on the same car.
Do all 1983 Renault R18i sub-models use the same tire size?
The covered 1983 Renault R18i sub-models share the same fitment choices. Both the Deluxe Sedan and Deluxe Wagon can use 155R13 and 175/70R13 radial tires, so the difference is not tied to one sub-model receiving a separate wheel diameter or a separate construction type.
Even with shared fitment across the sub-models, the right tire still depends on the actual wheels fitted to the car today. A sedan or wagon that has been changed over time may already be set up around one size, so confirming the existing wheel and tire combination is more useful than assuming either size belongs on every example automatically.
Choosing the Right Tire
What should I consider when choosing a 155R13 tire for a 1983 Renault R18i?
A 155R13 tire for a 1983 Renault R18i should first match the car's existing 13-inch wheel and overall setup. Within that size, the main choices come from radial tire series such as Michelin XAS-FF and Dunlop SP Sport Aquajet, both offered as blackwall tires with a traditional Euro-metric presentation.
Selection usually comes down to how closely the owner wants to preserve a period-style look versus simply maintaining correct size and wheel compatibility. It also helps to compare any stated rim-width specifications, along with details such as load capacity or tire weight when those figures matter for the way the car is driven and maintained.
What brands offer tires for the 1983 Renault R18i?
Tires for the 1983 Renault R18i are available from Michelin, Dunlop, and Avon across the applicable 13-inch radial sizes. Michelin and Dunlop cover the 155R13 size, while Avon appears in 175/70R13, giving the car a mix of traditional Euro-metric and more modern metric radial choices.
Brand choice should follow size and wheel confirmation, not replace it. Once the correct size is established, comparing the available brand offerings by tire series, sidewall treatment, rim-width suitability, and overall presentation will do more to narrow the right tire than choosing a brand name first.
What tire series are available for the 1983 Renault R18i?
The available tire series for the 1983 Renault R18i include Michelin XAS-FF, Dunlop SP Sport Aquajet, and Avon CR6ZZ. Those series are tied to the vehicle's two radial sizes, with Michelin and Dunlop appearing in 155R13 and Avon appearing in 175/70R13.
Series choice matters because it shapes the kind of tire presentation available within the correct fitment, even when all of the options use blackwall sidewalls. A Renault owner choosing among these series should start with the proper size for the car's wheels, then compare the tire's style, stated dimensions, and intended use on the road.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Renault R18i?
For a period-style 1983 Renault R18i, 155R13 is often the more traditional-looking starting point because it uses the older Euro-metric radial format rather than the lower-profile 175/70R13 metric size. Michelin XAS-FF and Dunlop SP Sport Aquajet both support that kind of blackwall imported-car presentation.
A restoration-oriented choice should still follow the actual wheel and tire setup on the car. Owners chasing exact historical accuracy should compare the car against marque references, old photos, or other vehicle-specific documentation, while drivers more focused on road use may simply want the size and overall appearance that best suits the car's current stance.
Does correct tire fitment matter for a 1983 Renault R18i restoration?
Correct tire fitment matters on a 1983 Renault R18i restoration because tire size strongly affects the car's stance, proportions, and overall period character. On a car of this era, moving between 155R13 and 175/70R13 changes more than the sidewall shape on paper; it changes how the finished car reads visually.
Fitment also matters mechanically, since restoration work often includes wheel refinishing, suspension service, and alignment changes that can influence the final tire choice. Before settling on a replacement, it helps to confirm the wheel diameter, wheel width, and whether the car is being restored to a traditional presentation or set up for more regular road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Renault R18i?
Modifications can affect tire fitment on a 1983 Renault R18i, even though both primary tire sizes use the same 13-inch rim diameter. Changes such as aftermarket wheels, altered wheel width, suspension work, lowering, or body clearance changes can influence whether 155R13 or 175/70R13 remains the better match.
That is especially important on older imported cars that may have changed hands several times. A careful check of wheel dimensions, tire-to-fender clearance, and steering clearance will give a better answer than relying on model-year fitment alone, particularly when choosing between a narrower Euro-metric tire and a wider 70-series metric radial.
What should I inspect before driving a 1983 Renault R18i on new tires?
Before driving a 1983 Renault R18i on new tires, inspect the wheels for correct diameter and condition, verify that the tires are seated properly, and confirm that inflation is appropriate for the tire and vehicle setup. It is also smart to check for suspension wear, alignment issues, and any rubbing at full steering lock.
Collector-era cars often sit for long periods, so the tire change is a good time to look beyond the rubber itself. Brake condition, wheel-bearing play, cracked valve stems, and uneven old-tire wear can all point to issues that should be addressed before regular road use or a longer first drive on the new set.
How should 155R13 and 175/70R13 tires on a collector 1983 Renault R18i be maintained?
155R13 and 175/70R13 tires on a collector 1983 Renault R18i should be maintained with regular pressure checks, periodic visual inspection, and routine attention to tread wear and sidewall condition. Even on low-mileage cars, aging, flat-spotting from storage, and slow air loss deserve as much attention as miles driven.
Good storage habits also help preserve tires on a lightly used Renault. Keeping the car away from prolonged sun, excess heat, moisture, and ozone sources can reduce premature deterioration, and occasional movement helps avoid one spot carrying the vehicle's weight too long. Any sign of cracking, bulging, or repeated pressure loss deserves prompt professional inspection.
