The 1998 Saturn SW2 came from the final years of Saturn’s original compact wagon formula, blending practical cargo room with the lightweight, polymer-bodied character that made the S-Series stand apart in the small-car market. For owners keeping one on the road today, tire selection is usually straightforward because the SW2 uses a single primary size, 185/65R15, in radial construction on a 15-inch rim. The real choice is less about fitment and more about presentation, since available options in this size include BFGoodrich Silvertown Radial tires with either a wide whitewall or redline sidewall. That makes this page especially useful for balancing everyday drivability with a more distinctive period-inspired look.
Which Tire Size Is Right for The 1998 Saturn SW2
The 1998 Saturn SW2 uses one primary tire size: 185/65R15, a radial tire for a 15-inch rim. The SW2 Base uses that same size, so the main decision is not which size fits, but which version of that size best matches the car’s look, wheel width, and intended use.
185/65R15 is a metric radial size in which 185 identifies the nominal section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 15 is the rim diameter in inches. On the 1998 Saturn SW2, that means a modern radial fitment rather than a vintage numeric or alphanumeric bias-ply size. Available choices in this size include BFGoodrich Silvertown Radial tires with either a wide whitewall or redline sidewall treatment. For an SW2 owner, the key is choosing the right visual style while confirming the wheel remains within the supported 5.00 to 6.50 inch rim-width range.
Sub-model fitment is simple for the 1998 Saturn SW2 because the covered configuration uses the same tire size throughout. Checking the exact sub-model still matters, but the SW2 Base stays with the same 185/65R15 radial setup on a 15-inch rim.

1998 Saturn SW2 Base
The 1998 Saturn SW2 Base uses the 185/65R15 radial tire size, so tire selection centers on choosing the right version of that fitment rather than sorting through multiple primary sizes. That keeps the decision focused on sidewall appearance, wheel-width compatibility, and the kind of road use the wagon is expected to see.
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.

Common questions for the 1998 Saturn SW2 usually center on 185/65R15 fitment, 15-inch wheel compatibility, sidewall-style choices, and what to inspect before putting a surviving S-Series wagon back into regular road use.
Tire Size & Fitment
What tire size fits a 1998 Saturn SW2?
The 1998 Saturn SW2 uses a 185/65R15 radial tire. That size combines a 185-millimeter section width, a 65-series profile, radial construction, and a 15-inch rim diameter, making it a modern metric radial fitment rather than an older bias-ply size designation.
Because the SW2 uses one primary size, the decision usually comes down to selecting the right tire style within 185/65R15 instead of choosing among multiple fitments. It is still smart to confirm the actual wheel on the car, especially if the wagon has had replacement wheels installed over the years or has been modified from its original setup.
What size rim does a 1998 Saturn SW2 use?
The 1998 Saturn SW2 uses a 15-inch rim with its 185/65R15 tire size. Available tires in this fitment are built around that 15-inch rim diameter, and the supported rim-width range for the applicable products is 5.00 to 6.50 inches.
Rim diameter is the first number to verify before mounting any new tire, since a 15-inch tire cannot be used on a different wheel diameter. Width matters too, particularly on an older daily driver or collector-kept wagon, because replacement wheels may not match the original setup even when the bolt pattern allows them to be installed.
Does the 1998 Saturn SW2 Base use the same tire size?
Yes. The 1998 Saturn SW2 Base uses the same 185/65R15 radial tire size as the covered 1998 Saturn SW2 fitment. That keeps sizing straightforward and avoids the kind of trim-level variation that can complicate tire selection on some vehicles.
Even with shared fitment, the tire choice can still vary by sidewall appearance and wheel-width compatibility. A buyer comparing options for an SW2 Base should focus on staying with the correct 15-inch radial size, then decide whether a more understated look or a more distinctive period-inspired sidewall better suits the car.
Choosing the Right Tire
What should I consider when choosing a 185/65R15 tire for a 1998 Saturn SW2?
Start with the correct size and construction: 185/65R15 in radial form for a 15-inch wheel. From there, compare the tire’s supported rim-width range, sidewall treatment, load capacity, and whether the overall look matches the way the 1998 Saturn SW2 is being kept or driven.
A wagon used as a clean survivor may call for a different visual presentation than one being refreshed with a custom touch. It also helps to look at the actual wheels on the car, since a tire can be the right size on paper yet still need a width check to make sure the wheel and tire combination stays within the intended fitment range.
What sidewall styles are available for 1998 Saturn SW2 tires?
For the 1998 Saturn SW2 in 185/65R15, available sidewall styles include a 1.75 inch wide whitewall and a redline. Both are offered in the BFGoodrich Silvertown Radial series, so the difference is primarily visual rather than a change in the basic size or construction.
That makes sidewall style an appearance decision more than a fitment decision, but it still affects the personality of the car. A wide whitewall gives the SW2 a more unusual custom or retro presentation, while a redline adds a sportier period-style accent without changing the underlying radial size or 15-inch wheel requirement.
What brands offer tires for the 1998 Saturn SW2?
The available products for the 1998 Saturn SW2 in 185/65R15 come from BFGoodrich. Both applicable options use the Silvertown Radial series and share the same radial construction, load figure of 1168@35 psi, and 15-inch rim diameter.
Since brand variety is limited here, the buying decision shifts toward sidewall style and wheel-width compatibility rather than comparing several manufacturers. That can actually simplify the process for an SW2 owner, because the core fitment stays the same and the most visible difference comes down to whether the tire should look more conservative or more custom.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Saturn SW2?
A period-style choice for a 1998 Saturn SW2 starts with the correct 185/65R15 radial size on a 15-inch rim. Within that fitment, the available BFGoodrich Silvertown Radial options let the owner decide whether the wagon should carry a more understated look or a stronger visual statement.
For a restoration-oriented project, the best choice depends on the character you want the car to present rather than on size changes, since the primary fitment remains the same. When exact originality matters, it helps to compare the tire’s sidewall presentation against period photos, showroom literature, or Saturn enthusiast references before settling on a final look.
How does tire construction affect the appearance of a restored 1998 Saturn SW2?
On a restored 1998 Saturn SW2, construction has less visual impact than it would on an older collector car because the primary fitment is already a radial. The more noticeable appearance difference comes from sidewall treatment, with wide whitewall and redline versions creating very different impressions while keeping the same basic size.
That means a restoration-minded owner can stay with the proper radial format and still shape the car’s personality through sidewall styling. A subtle presentation usually favors a cleaner, less attention-grabbing look, while whitewall or redline accents can push the wagon toward a custom or nostalgic theme without changing the 185/65R15 fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Saturn SW2?
Yes. Even though the 1998 Saturn SW2 uses a straightforward 185/65R15 radial fitment, changes such as aftermarket wheels, altered ride height, replacement suspension parts, or body modifications can affect how that tire sits in the wheel opening and how it clears nearby components.
A modified SW2 should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and normal suspension travel before new tires are chosen. Small wagon platforms do not leave much room for guessing, so it is worth confirming the current setup on the car rather than assuming every 15-inch wheel and tire combination behaves the same way.
What should I inspect before driving a 1998 Saturn SW2 on new tires?
Before driving a 1998 Saturn SW2 on new tires, inspect the wheels for damage, confirm the wheel size matches the tire, and check that the valve stems, lug hardware, and overall wheel condition are sound. It also makes sense to look over alignment-related wear points such as steering and suspension components.
A fresh set of tires can only perform as intended if the surrounding hardware is in good condition. Tire pressure, visible clearance around struts and fenders, and even wear during the first miles are all worth monitoring, especially on an older wagon that may have spent long stretches parked or may have unknown maintenance history.
How often should tires on a 1998 Saturn SW2 be inspected?
Tires on a 1998 Saturn SW2 should be inspected regularly, not just when tread looks low. A visual check for cracking, cuts, bulges, punctures, uneven wear, and slow air loss is a good habit on any aging vehicle, and it becomes even more important when the car sees occasional use rather than steady daily mileage.
Collector-kept and lightly driven cars can age tires out before they wear them out, so condition matters as much as tread depth. Checking pressure and sidewall condition before longer drives is especially wise, since an older wagon may spend time sitting between outings and can develop problems that are easy to miss during routine around-town use.
