The 1998 Cadillac Seville came from the final stretch of Cadillac’s front-wheel-drive luxury sedan era, when the brand was blending traditional comfort with sharper, more contemporary road manners. In SLS and STS form, the Seville appealed to buyers who wanted a full-size Cadillac feel without giving up modern handling and highway composure. For this exact model year, the primary fitment is a 235/60R16 radial on a 16-inch rim. That keeps the decision focused less on size and more on sidewall presentation, tire series, and whether the car is being kept visually stock-appearing or driven as a road car. The right choice starts with matching the Seville’s 16-inch wheel setup and intended appearance.
Which Tire Size Is Right for The 1998 Cadillac Seville
The 1998 Cadillac Seville uses one primary tire size: 235/60R16. It is a radial fitment for a 16-inch rim, and that same size carries across the covered SLS and STS sub-models, including Touring Package versions. That means the main decision is not which primary size fits, but which 235/60R16 tire best matches the car’s appearance, wheel setup, and intended use.
Fit(s): SLS, SLS w/Touring Pkg., STS, and STS w/Touring Pkg.
Construction: Radial|Rim: 16 in
A 235/60R16 size uses a 235-millimeter nominal section width, a 60-series profile, radial construction, and a 16-inch rim diameter. On a 1998 Cadillac Seville, this is the standard modern radial format and it suits the car’s late-1990s luxury-sedan character well. Available choices include blackwall, narrow whitewall, wide whitewall, redline, and goldline sidewall styles, along with American Classic and Michelin offerings in different tire series. The practical choice comes down to whether the Seville is being kept with a traditional Cadillac visual theme or equipped for a more contemporary road-going presentation.
Tire fitment is straightforward across the covered 1998 Cadillac Seville sub-models because each one uses the same 235/60R16 radial size. Checking the exact sub-model still helps when narrowing down appearance and usage goals, especially between more traditional luxury presentation and sport-oriented trim identity.

1998 Cadillac Seville SLS
The 1998 Cadillac Seville SLS uses the 235/60R16 radial size on a 16-inch rim. Tire selection is mainly about choosing the right sidewall style and product character for a luxury-oriented sedan, rather than sorting through multiple primary fitment sizes.
The 1998 Cadillac Seville SLS w/Touring Pkg. also uses the 235/60R16 radial fitment. That keeps sizing simple, so attention can shift to wheel compatibility, preferred sidewall treatment, and whether the car is being preserved with a traditional Cadillac look or driven regularly.
The 1998 Cadillac Seville STS shares the same 235/60R16 radial tire size. With fitment unchanged, the key decision is selecting a tire that matches the car’s intended balance of upscale appearance, everyday road use, and the owner’s preference for blackwall or specialty sidewall styling.
The 1998 Cadillac Seville STS w/Touring Pkg. uses the same 235/60R16 radial setup as the other covered Seville versions. Because the primary size stays consistent, buyers can focus on comparing tire series, sidewall appearance, and wheel-width compatibility before making a final choice.
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 1998 Cadillac Seville?
The 1998 Cadillac Seville uses a 235/60R16 radial tire. That fitment applies across the covered Seville sub-models, including the SLS, SLS w/Touring Pkg., STS, and STS w/Touring Pkg., so the primary tire-size question is unusually simple for this model year.
Once the size is confirmed, the next step is choosing the right 235/60R16 tire style for the car. Available options differ by sidewall treatment, brand, and tire series, so the decision usually comes down to the look you want and whether the car remains on its correct 16-inch wheel setup.
What size rim does a 1998 Cadillac Seville use?
The 1998 Cadillac Seville uses a 16-inch rim with its 235/60R16 tire size. The tire size itself confirms the 16-inch wheel diameter, and the available products in this fitment are built around that same rim diameter for Seville applications.
Wheel diameter is the first thing to verify if the car has had wheel changes over the years. A Seville with aftermarket wheels, replacement factory-style wheels, or altered suspension should have its actual wheel diameter and width checked before choosing among 235/60R16 tires.
Do all 1998 Cadillac Seville sub-models use the same tire size?
Yes. The covered 1998 Cadillac Seville sub-models all use the same 235/60R16 radial tire size. That includes the SLS, SLS w/Touring Pkg., STS, and STS w/Touring Pkg., so there is no split fitment to sort out between those versions.
That consistency makes tire buying easier because the main variables are no longer the size or rim diameter. Instead, the useful comparisons are sidewall appearance, tire series, rim-width compatibility, and whether the Seville is being maintained as a traditional luxury sedan or driven more frequently.
Choosing the Right Tire
What should I consider when choosing a 235/60R16 tire for a 1998 Cadillac Seville?
Start with the correct size, 235/60R16, and confirm that the Seville still has a compatible 16-inch wheel setup. From there, compare construction, rim-width range, sidewall style, and the overall character of each tire, especially if the car is being kept as a luxury cruiser or driven more regularly.
A blackwall tire gives the Seville a more modern, understated look, while whitewall, redline, and goldline options create a more custom or traditional presentation. It also helps to compare details such as maximum load figures where given, tire weight, and the wheel-width range your specific wheels actually measure.
What sidewall styles are available for 1998 Cadillac Seville tires?
The 1998 Cadillac Seville has 235/60R16 tire choices in several sidewall styles, including blackwall, narrow whitewall, wide whitewall, redline, and goldline. That gives this car more visual flexibility than many late-1990s fitments, especially for owners who want a more distinctive appearance.
The right sidewall depends on how the Seville is being presented. A whitewall can complement the car’s formal Cadillac personality, while blackwall keeps the look more contemporary. Redline and goldline options move the appearance in a more personalized direction, so the best choice is usually the one that matches the car’s overall theme.
What brands offer tires for the 1998 Cadillac Seville?
235/60R16 tires for the 1998 Cadillac Seville are available from American Classic and Michelin. American Classic covers several appearance-driven options in this size, while Michelin offers a blackwall radial choice that suits a more modern touring-oriented presentation.
Brand choice should still be filtered through the basics of fitment and appearance. Some buyers will focus on whitewall or specialty sidewall styling, while others will prefer a blackwall touring look. Comparing the tire series, wheel-width range, and any available load details will narrow the field more effectively than brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Cadillac Seville?
A period-style 1998 Cadillac Seville usually starts with the correct 235/60R16 size and a sidewall treatment that matches the car’s intended presentation. Narrow whitewall or wide whitewall options can give the Seville a more formal Cadillac look, while blackwall keeps the appearance closer to a contemporary late-1990s road car.
The best visual choice depends on whether the goal is showroom-era luxury, a custom look, or a subtle modern replacement. When exact originality matters, it is worth checking factory literature, marque references, or vehicle-specific documentation before settling on a whitewall width, stripe style, or tire series.
Does correct tire fitment matter for a 1998 Cadillac Seville restoration?
Yes, correct tire fitment matters because the 235/60R16 size helps preserve the Seville’s intended stance, wheel-to-tire proportion, and overall visual balance. Even on a newer collector-era Cadillac, the wrong size can make the car look noticeably off and may change how it sits within the wheel openings.
Fitment also affects the restoration process beyond appearance. A Seville restored with replacement wheels, suspension work, or cosmetic changes should have its actual wheel dimensions checked before tires are chosen. Keeping the correct size is the foundation, then sidewall style and tire series can refine the final presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Cadillac Seville?
Yes. Even though the standard fitment is 235/60R16, modifications can change what works safely and cleanly on a 1998 Cadillac Seville. Wheel swaps, altered wheel width, offset changes, suspension lowering, or body modifications can all affect clearance and the way the tire sits on the car.
A Seville that has been changed from stock should have the actual wheel diameter and width verified before tires are selected. It also makes sense to check steering clearance, fender room, and the tire’s approved wheel-width range so the final combination suits the car’s current setup.
What should I inspect before driving a 1998 Cadillac Seville on new tires?
Before driving a 1998 Cadillac Seville on new tires, inspect the wheels for damage, confirm the wheel dimensions, and make sure the tires are inflated properly for service. It is also smart to check suspension condition, alignment-related wear issues, and any signs that the old tires were rubbing or wearing unevenly.
A careful road-use check should include valve stems, lug hardware, and visible clearance around the fenders and suspension at full steering lock. On a car that may have spent long periods parked, checking for age-related issues elsewhere in the chassis helps the new 235/60R16 tires perform as intended.
How often should tires on a 1998 Cadillac Seville be inspected?
Tires on a 1998 Cadillac Seville should be inspected regularly, especially if the car sees infrequent use or spends long periods stored. Look over tread wear, air pressure, sidewall cracking, bulges, cuts, and any signs of slow air loss, even when the car appears to be driven only occasionally.
Low-mile collector-era cars can still age their tires even when tread depth looks acceptable. A quick visual inspection before each drive and a more careful periodic check of pressure, condition, and wear pattern can catch problems early and help the Seville stay smooth, safe, and road-ready.
