The 1993 Audi 90 came from an era when Audi was refining its reputation for solid road manners, understated styling, and confident all-weather usability in a compact luxury sedan. Buyers looking at one today are often balancing daily-driver practicality with the appeal of a well-kept German modern classic. For this exact model, the primary fitment is a 195/65R15 radial on a 15-inch rim, which keeps tire selection fairly straightforward. The main decision is less about sorting through multiple sizes and more about choosing the right radial tire for appearance, intended use, and wheel compatibility. That makes careful attention to wheel condition, overall tire age, and actual vehicle setup especially important.
Which Tire Size Is Right for The 1993 Audi 90
The 1993 Audi 90 uses one primary tire size: 195/65R15, a radial fitment for a 15-inch rim. Both covered sub-models share that same size, so the fitment question is usually straightforward. The real choice comes down to selecting the right radial tire for the car's intended use, confirming the wheel setup is still stock or compatible, and checking overall condition before putting the car back on the road.
The 195/65R15 size uses a modern metric radial format: 195 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On a 1993 Audi 90, this is a contemporary fitment style that suits the car's original-era balance of comfort, handling, and everyday road use. Because the sizing is familiar and widely understood, the focus shifts to choosing a tire that matches the vehicle's use and wheel condition. It is also wise to confirm that the car still has the correct 15-inch wheels before making a final selection.
Tire fitment stays consistent across the covered 1993 Audi 90 sub-models, which simplifies size selection. Even so, checking the exact sub-model is still worthwhile so the tire choice matches the car's wheel setup and current condition.

1993 Audi 90 CS
The 1993 Audi 90 CS uses the same 195/65R15 radial fitment as the other covered sub-model. That keeps size selection simple and lets the decision center on choosing the right radial tire while confirming the car still wears the proper 15-inch wheel setup.
The 1993 Audi 90 S also uses 195/65R15 radial tires, so there is no size split to sort through between covered versions. The practical next step is making sure wheel diameter and overall vehicle setup remain correct, especially if the car has seen replacement wheels over the years.
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.
Frequently Asked Questions
Common questions for the 1993 Audi 90 usually center on its single tire size, 15-inch rim fitment, radial construction, and what to inspect before putting a low-use or recently revived car back into service.
Tire Size & Fitment
What tire size fits a 1993 Audi 90?
The 1993 Audi 90 uses a 195/65R15 tire size. This is a modern metric radial size, and it is the primary fitment for the covered model range, including both the CS and S sub-models.
That single-size fitment makes the first step fairly simple, but it is still smart to confirm that the car has the proper 15-inch wheels before selecting tires. On an older Audi, replacement wheels, long-term storage, or previous owner changes can alter what is currently on the car, so a quick check of the wheel and existing tire markings helps avoid ordering the wrong setup.
What size rim does a 1993 Audi 90 use?
The primary tire fitment for the 1993 Audi 90 mounts on a 15-inch rim. The 195/65R15 size itself confirms that wheel diameter, since the final number in the size code identifies the rim diameter in inches.
Rim diameter is only one part of the fitment picture, so it should not be the only thing checked. A 15-inch wheel still needs to be appropriate in width and properly suited to the car's setup. On a vehicle of this age, it is also worth inspecting for bent wheels, corrosion, or non-stock replacements before mounting new tires.
Do all 1993 Audi 90 sub-models use the same tire size?
Yes. The covered 1993 Audi 90 CS and 1993 Audi 90 S both use the same 195/65R15 radial tire size. There is no sub-model split here that sends one version to a different primary size.
That consistency simplifies shopping, but it does not remove the need to verify what is actually on the car today. Collector-age sedans often pick up aftermarket wheels or mixed replacements over time. Matching the new tires to the correct wheel diameter and confirming there are no clearance issues from prior modifications is still a sensible final check.
Choosing the Right Tire
What should I consider when choosing a 195/65R15 tire for a 1993 Audi 90?
Start with the correct size and construction: the 1993 Audi 90 uses a 195/65R15 radial tire. Once that is established, the important factors become wheel compatibility, intended driving use, and the overall condition of the vehicle's suspension and steering components.
A car used for occasional fair-weather driving may lead to a different choice than one covering regular road miles, even within the same size. It also helps to inspect the existing wheels for damage or corrosion and confirm that the Audi still has a proper 15-inch setup. Choosing by size alone can miss issues that affect ride quality, clearance, and long-term satisfaction.
How do I choose between the available 195/65R15 tires for a 1993 Audi 90?
With a single primary size, the 1993 Audi 90 is less about deciding between fitments and more about deciding between tire characteristics within 195/65R15. The key is selecting a radial tire that suits how the car is actually used and the condition of the wheels it will be mounted on.
Think about whether the Audi is a regularly driven sedan, a lightly used preserved car, or something in between. A careful buyer should also look at the current tire wear pattern, which can reveal alignment or suspension issues before new tires go on. That approach makes the final choice more informed than simply replacing what is already mounted.
What rim-fitment details should I compare when choosing tires for a 1993 Audi 90?
The first rim-fitment detail is diameter, and for the 1993 Audi 90 that means a 15-inch wheel to match the 195/65R15 tire size. Beyond that, the wheel itself should be in good condition and appropriate for the tire being installed.
Aging wheels can develop corrosion, impact damage, or bead-seat issues that affect how a tire mounts and seals. If the car has replacement wheels, it is also wise to confirm that the setup still clears suspension and bodywork correctly. Those checks matter just as much as choosing the proper size, especially on a car that may not have seen frequent recent use.
Restoration & Appearance
Which tire should I choose for a period-style 1993 Audi 90?
A period-style approach for a 1993 Audi 90 starts with staying in the correct 195/65R15 radial size. That keeps the car aligned with its original-era fitment approach and preserves the proportions expected on a compact luxury sedan from the early 1990s.
From there, the right choice depends on whether the goal is a clean driver-quality presentation or a more carefully researched restoration. Tire appearance can influence the overall look of the car, but exact originality claims should be checked against marque references, period photos, or model-specific documentation. Size and overall stance should remain the foundation of any appearance-minded decision.
Does correct tire fitment matter for a 1993 Audi 90 restoration?
Yes, correct tire fitment matters because tire size has a direct effect on stance, visual balance, and how authentically the 1993 Audi 90 presents. Using the proper 195/65R15 size helps keep the car in the right visual range for its era and intended character.
Restoration-minded owners should also look beyond the size stamp and inspect the wheels themselves. A clean, properly sized tire on a damaged or incorrect wheel can still undermine the finished result. Even on a driver-focused restoration, keeping wheel diameter and overall tire proportions appropriate usually has a noticeable effect on the car's appearance and road manners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 Audi 90?
Yes, modifications can affect tire fitment on a 1993 Audi 90 even when the intended tire size remains 195/65R15. Aftermarket wheels, altered suspension height, or body changes can influence clearance, steering travel, and how the tire sits within the wheel opening.
A car that still uses a 15-inch wheel is not automatically configured like a stock example. Wheel width, offset, and suspension condition all deserve a quick review before new tires are installed. Taking those measurements and checking for rubbing marks or limited clearance helps prevent fitment surprises once the car returns to regular road use.
What should I inspect before driving a 1993 Audi 90 on new tires?
Before driving a 1993 Audi 90 on new tires, inspect the wheels, valve stems, alignment condition, and the visible state of suspension and steering components. It is also smart to verify that the old tires did not show uneven wear, since that can point to issues that new tires alone will not correct.
Air pressure should be set correctly and checked again after the first few drives, especially on a car that has been sitting. A short test drive can reveal vibration, pulling, or rubbing that was not obvious during installation. Catching those problems early helps protect the new tires and gives a clearer picture of the car's overall road readiness.
How often should tires on a 1993 Audi 90 be inspected?
Tires on a 1993 Audi 90 should be inspected regularly, especially if the car is driven infrequently. A quick visual check before use and a more careful inspection at routine service intervals helps catch cracking, air loss, tread wear, bulges, or damage before they become bigger problems.
Low-mileage collector-era cars can age their tires out long before the tread is gone, so appearance and condition matter as much as mileage. Checking pressure, sidewalls, and the tread surface after storage is a sensible habit. Consistent inspection is particularly important on a preserved sedan that may spend long periods parked between drives.
