The 1998 Saturn SL2 came from an era when Saturn leaned hard into compact-car practicality, polymer body panels, and a distinct small-car identity in the American market. As the upscale sedan version of the S-Series, the SL2 blended economy-car efficiency with a more finished, everyday-driver feel than many late-1990s compacts. Tire fitment for the 1998 Saturn SL2 is straightforward, using a 185/65R15 radial on a 15-inch rim. Within that size, the available choices focus less on fitment changes and more on presentation, including Silvertown Radial options with wide whitewall or redline sidewalls. That makes selection largely a matter of wheel compatibility, appearance, and the kind of period-inspired look you want the car to carry.
Which Tire Size Is Right for The 1998 Saturn SL2
The 1998 Saturn SL2 uses one primary tire size: 185/65R15, a metric radial designed for a 15-inch rim. The SL2 Base uses that same size, so the main decision is not which size fits, but which version of that size best matches your wheels, your intended look, and the style you want the car to present on the road.
185/65R15 is a modern metric radial size where 185 indicates nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1998 Saturn SL2, that makes it the primary fitment for a 15-inch wheel setup. Available choices in this size center on BFGoodrich Silvertown Radial models, with sidewall treatments including a 1.75-inch whitewall and a redline. That gives the buyer a straightforward path: keep the correct size, then choose the sidewall style and wheel compatibility that best suit the car's appearance.
Sub-model fitment is simple for the 1998 Saturn SL2 because the covered sub-model uses the same primary tire size. Checking the exact sub-model still matters, but tire selection here is mostly about choosing the right version of the correct 15-inch radial fitment.

1998 Saturn SL2 Base
The 1998 Saturn SL2 Base uses the same 185/65R15 radial fitment as the model core, keeping tire selection straightforward. That lets the focus shift from size changes to choosing the sidewall treatment and confirming the wheel matches the tire's intended rim-width 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.

Common questions for the 1998 Saturn SL2 usually come down to the 185/65R15 tire size, 15-inch rim fitment, sidewall style choices, and what to inspect before putting a collector-minded or lightly driven car back on the road.
Tire Size & Fitment
What tire size fits a 1998 Saturn SL2?
The 1998 Saturn SL2 uses a 185/65R15 radial tire. That size is the primary fitment for the model, and the SL2 Base uses the same 185/65R15 size as well.
Since fitment is centered on one size, the key step is making sure the car still has the correct 15-inch wheels and that wheel width falls within the tire's compatible range. If the car has aftermarket wheels or suspension changes, confirm wheel specifications and clearance before choosing between the available sidewall styles.
What size rim does a 1998 Saturn SL2 use?
The 1998 Saturn SL2 uses a 15-inch rim with its 185/65R15 tire size. Available tires in this size are built for that 15-inch wheel diameter, so matching the wheel diameter is essential before any tire is installed.
Wheel diameter is only part of the fitment picture, so it also helps to confirm actual wheel width. The available 185/65R15 products in this application are suited to rims from 5.00 to 6.50 inches wide, which gives a useful checkpoint if the car has replacement wheels or has been changed from its original setup.
Does the 1998 Saturn SL2 Base use the same tire size?
Yes. The 1998 Saturn SL2 Base uses the same 185/65R15 radial tire size as the overall 1998 Saturn SL2 fitment. That keeps size selection simple and avoids the sub-model split seen on some vehicles.
Because the size stays the same, the real choice becomes how you want the tire to look and whether the wheel on the car matches the tire's intended specifications. A buyer can focus on sidewall style, tire presentation, and wheel compatibility instead of sorting through multiple primary fitment sizes.
Choosing the Right Tire
What should I consider when choosing a 185/65R15 tire for a 1998 Saturn SL2?
Start with the correct size and construction: the 1998 Saturn SL2 uses a 185/65R15 radial. From there, compare wheel compatibility, sidewall style, and the kind of appearance you want, since the available options stay within the same size and Silvertown Radial series.
A practical choice comes down to how the car will be presented and driven. Confirm that the wheel is a 15-inch rim and that its width suits the tire, then decide whether a wide whitewall or redline better matches the car's look. For a clean installation, also inspect clearance and the overall condition of wheels and suspension parts.
What sidewall styles are available for 1998 Saturn SL2 tires?
The available 185/65R15 tires for the 1998 Saturn SL2 include two distinct sidewall treatments: a 1.75-inch wide whitewall and a redline. Both are offered in the BFGoodrich Silvertown Radial series, so the size and basic construction remain consistent while the appearance changes.
That makes sidewall style the main visual decision for this fitment. A wide whitewall gives the car a more classic, dressed-up presentation, while a redline creates a sportier vintage-style accent. Either way, the smart next step is confirming wheel compatibility and choosing the sidewall that best fits the Saturn's intended finish and use.
How do I choose between the available 185/65R15 tires for a 1998 Saturn SL2?
The available choices are closely related, so the biggest difference is visual treatment rather than basic fitment. Both options are BFGoodrich Silvertown Radial tires in 185/65R15, with the same 15-inch rim diameter and similar load and wheel-width specifications.
That means selection should be driven by the look you want the car to carry and whether the wheel setup is correct. Compare the whitewall and redline presentation against the car's paint, trim, and overall style, then verify that the wheels measure within the tire's intended width range before making the final choice.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Saturn SL2?
A period-style starting point for a 1998 Saturn SL2 begins with the correct 185/65R15 radial size on a 15-inch rim. Within that fitment, the available BFGoodrich Silvertown Radial options allow the car to lean toward a more traditional visual presentation without changing the underlying size.
The choice then becomes one of character rather than basic fitment. A wide whitewall gives the SL2 a more formal retro look, while a redline adds a sportier accent. If exact restoration authenticity matters, compare those appearance choices against marque references, period photos, or other vehicle-specific historical sources before deciding.
How does tire construction affect the appearance of a restored 1998 Saturn SL2?
On the 1998 Saturn SL2, the available fitment stays within radial construction, so the appearance difference comes more from sidewall treatment than from switching between bias-ply and radial forms. In practical terms, the visual impact is created by choosing a whitewall or redline in the correct 185/65R15 size.
Keeping the proper size helps preserve the car's stance and overall proportion, while the sidewall style shapes how restoration-oriented or customized the final presentation feels. Before focusing only on appearance, make sure the wheel diameter and width are correct so the finished look is supported by sound fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Saturn SL2?
Yes. Even though the standard fitment is a 185/65R15 radial on a 15-inch rim, modifications can change what actually fits on the car. Aftermarket wheels, altered wheel width, suspension changes, or body modifications can all affect clearance and overall compatibility.
A careful check should include wheel diameter, wheel width, and visible clearance at the fenders and steering components. Cars that have been lowered or fitted with non-stock wheels deserve extra attention, because the correct original tire size does not automatically mean the current setup has enough room in every driving condition.
What should I inspect before driving a 1998 Saturn SL2 on new tires?
Before road use, inspect the wheels for damage, confirm the wheel diameter and width, and make sure the new tires are mounted in the correct 185/65R15 size. It also helps to check for suspension wear, alignment concerns, and any signs that the previous tires rubbed or wore unevenly.
Once the new tires are installed, verify air pressure, look for any immediate clearance concerns at full steering lock, and keep an eye on how the car tracks during the first miles. A brief recheck for air loss, unusual vibration, or contact marks can catch small installation or fitment issues early.
How often should tires on a 1998 Saturn SL2 be inspected?
Tires on a 1998 Saturn SL2 should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Look for cracking, bulges, cuts, uneven wear, low pressure, and any change in how the car rides or steers.
Collector-minded or low-use cars can develop tire condition issues long before the tread appears worn out, so visual checks matter as much as mileage. A good habit is to inspect the tires before longer drives and after storage periods, while also watching for slow air loss and checking that the sidewalls remain clean and undamaged.
