The 1981 Nissan 200SX came from an era when compact Japanese coupes were blending everyday drivability with sharper styling and a more European-influenced road feel. For owners today, that makes tire choice an important part of preserving both the car’s stance and the way it responds on the road. The 1981 Nissan 200SX uses a 185/70R14 radial tire on a 14-inch rim, so the fitment decision is more about selecting the right version of that size than sorting through multiple primary sizes. Available choices include traditional blackwall radials as well as a wide whitewall option, giving room for either a sportier or more customized presentation.
Which Tire Size Is Right for The 1981 Nissan 200SX
The 1981 Nissan 200SX uses one primary tire size: 185/70R14. That is a radial fitment on a 14-inch rim, and the same size carries across the covered 200SX Base model, so the main decision is choosing the right tire within that size based on sidewall style, tire series, intended use, and wheel compatibility.
185/70R14 is a metric radial size in which 185 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 14 is the wheel diameter in inches. For the 1981 Nissan 200SX, this is the core fitment size and keeps the car in the sizing format associated with its era. Available choices in this size include blackwall offerings from Avon, Dunlop, Michelin, and Vredestein, along with a BFGoodrich Silvertown Radial wide whitewall. That gives buyers room to match the tire to a stock-style road car, a more sporting presentation, or a custom look while still staying within the correct primary size.
Tire fitment is straightforward for the covered 1981 Nissan 200SX sub-models. The available sub-model shares the same primary size, so the focus shifts from identifying a different fitment to choosing the right tire style and construction details within that size.

1981 Nissan 200SX Base
The 1981 Nissan 200SX Base uses the same 185/70R14 radial fitment found on the model core. That keeps tire selection centered on blackwall versus wide whitewall appearance, tire series, and confirming that the wheel width matches the tire’s intended range.
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 1981 Nissan 200SX?
The 1981 Nissan 200SX uses a 185/70R14 radial tire. That size applies to the covered 200SX Base model as well, so there is one primary fitment to focus on rather than multiple factory tire sizes within this page.
Once the size is confirmed, the real choice becomes which 185/70R14 tire best suits the car’s intended use and appearance. It is still smart to confirm the actual wheels on the car, especially if a previous owner changed rims, altered suspension height, or installed aftermarket wheels that could affect width compatibility or clearance.
What size rim does a 1981 Nissan 200SX use?
The primary tire fitment for the 1981 Nissan 200SX is built around a 14-inch rim diameter. That matches the 185/70R14 size, where the final number in the size code identifies the wheel diameter the tire is designed to mount on.
Rim diameter is only part of the fitment picture, so wheel width still matters when comparing tire choices. Several available 185/70R14 products are intended for slightly different width ranges, making it worthwhile to measure the wheel before choosing a tire, especially on a car that may no longer be wearing its original rims.
What does 185/70R14 mean on a 1981 Nissan 200SX?
In 185/70R14, the 185 is the nominal section width in millimeters, 70 is the aspect ratio, R means radial construction, and 14 is the wheel diameter in inches. It is a modern metric radial format rather than an older numeric or alphanumeric bias-ply size code.
Understanding the code helps when comparing products that share the same basic size but differ in series, sidewall style, or detailed specifications. It also helps prevent buying a tire that looks close on paper but belongs to a different diameter or sizing system, which can create mounting or clearance problems on the 200SX.
Choosing the Right Tire
What should I consider when choosing a 185/70R14 tire for a 1981 Nissan 200SX?
Start with the correct primary size, which is 185/70R14, then compare construction, sidewall appearance, intended wheel-width range, and the tire series available in that size. For the 1981 Nissan 200SX, all of the listed choices are radials, but they vary in presentation and detailed specifications.
A blackwall tire usually suits a cleaner sport-coupe look, while the wide whitewall option creates a more customized appearance. Beyond looks, check the wheel width on the car, compare load information where relevant, and think about whether the 200SX will be used for occasional shows, regular fair-weather driving, or more enthusiastic road use.
What sidewall styles are available for 1981 Nissan 200SX tires?
The available 185/70R14 tires for a 1981 Nissan 200SX come in both blackwall and wide whitewall styles. Most of the choices in this size are blackwall radials, while the BFGoodrich Silvertown Radial offers a 2.25-inch whitewall for a distinctly different visual treatment.
Sidewall style does not change the basic fitment size, but it can change the entire character of the car. A blackwall generally keeps the 200SX looking more understated and sporting, while a wide whitewall leans toward a custom or nostalgic presentation, so the best choice depends on the look the owner wants to preserve or create.
What brands offer tires for the 1981 Nissan 200SX?
185/70R14 tires for the 1981 Nissan 200SX are available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein. Those options cover several radial tire series, including Silvertown Radial, CR6ZZ, Sport Classic, Michelin XAS, and Sprint Classic.
Brand choice is only one part of the decision, because sidewall style, wheel-width range, and the overall character of the tire matter just as much. Comparing those factors side by side helps narrow the field more effectively than choosing by brand name alone, especially when the goal is to match the tire to the car’s use and appearance.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Nissan 200SX?
A period-style approach to a 1981 Nissan 200SX starts with the correct primary size, 185/70R14, and then narrows the choice by visual character. Blackwall radials usually preserve the coupe’s era-appropriate sporty presentation, while the available wide whitewall introduces a more customized and less typical look for this kind of car.
The best choice depends on whether the goal is a stock-appearing driver, a personalized show car, or a restoration influenced by period accessories and regional style. When exact originality matters, period photos, sales literature, and marque-specific references are the right tools for deciding which sidewall presentation best suits the individual car.
Does correct tire fitment matter for a 1981 Nissan 200SX restoration?
Correct tire fitment matters because it affects both appearance and proportion on a 1981 Nissan 200SX. Staying with the proper 185/70R14 size helps keep the visual balance of the car intact and avoids the oversized or undersized look that can quickly make a restoration feel off.
Fitment also matters beyond looks, since wheel compatibility and clearance still need to be respected even on a carefully restored car. A 200SX that has sat for years or changed hands several times may no longer have its original wheels, so checking the actual rim width and overall setup is a worthwhile part of the restoration process.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Nissan 200SX?
Yes, modifications can affect tire fitment on a 1981 Nissan 200SX even when the tire size remains 185/70R14. Aftermarket wheels, different wheel widths, suspension changes, lowering, and body alterations can all change how much clearance the tire has at the fender, suspension, and steering components.
That is why the actual wheel and chassis setup should be checked before choosing a tire by size alone. On a modified car, the important details include wheel diameter, width, and offset, along with lock-to-lock steering clearance and available space under compression, so the selected tire suits the car as it sits now.
What should I inspect before driving a 1981 Nissan 200SX on new tires?
Before driving a 1981 Nissan 200SX on new tires, inspect the wheels for damage, verify the rim diameter and width, and make sure the tires are mounted and inflated properly. It also helps to check for suspension wear, alignment issues, and any interference points that could affect the new 185/70R14 tires.
A careful walkaround should also include looking at valve stems, lug hardware, and general brake and steering condition, especially on a car that has spent long periods in storage. The first miles are a good time to listen for rubbing, feel for vibration, and recheck pressure so any fitment or mechanical issue is caught early.
How should 185/70R14 tires on a collector 1981 Nissan 200SX be maintained?
Collector-car tire care starts with regular pressure checks, routine visual inspections, and attention to age-related condition even if the tread still looks good. On a 1981 Nissan 200SX, 185/70R14 tires should be watched for cracking, bulges, cuts, flat spotting from storage, and unexplained air loss.
Storage conditions matter almost as much as mileage on a lightly used coupe. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires, while occasional movement and periodic inspections help catch developing problems before a weekend drive or longer road outing.
