The 1993 Audi 100 Quattro comes from an era when Audi had firmly established its reputation for refined all-weather performance, understated design, and confident highway manners. For many owners, this model sits at the intersection of modern drivability and emerging collector interest, especially because the Quattro system gives it a distinct place among early 1990s European sedans. Tire fitment is refreshingly straightforward, with a single 195/65R15 radial size on a 15-inch rim. That simplicity shifts the decision toward choosing the right road-oriented tire character and confirming wheel compatibility. For a well-kept driver, the focus is less on size confusion and more on condition, proper fit, and intended use.
Which Tire Size Is Right for The 1993 Audi 100 Quattro
The 1993 Audi 100 Quattro uses one primary tire size: 195/65R15 in radial construction on a 15-inch rim. The covered Quattro sub-model shares that same fitment, so the main decision is not between multiple factory sizes, but between tire choices that suit the car's original road-going character, wheel setup, and current condition.
195/65R15 is a metric radial size in which 195 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 1993 Audi 100 Quattro, this modern sizing format matches the car's more contemporary tire and wheel layout rather than an earlier bias-ply or vintage alphanumeric system. Its role is to preserve the intended fitment baseline for a 15-inch wheel. Before choosing any tire in this size, confirm the actual wheel dimensions on the car and inspect for suspension, alignment, or clearance issues that could affect fit.
Tire fitment is simple across the covered 1993 Audi 100 Quattro sub-models because the same primary size is used throughout. Checking the exact sub-model still helps confirm that the car remains on its proper wheel and tire combination before comparing replacement options.

1993 Audi 100 Quattro CS
The 1993 Audi 100 Quattro CS uses the same 195/65R15 radial fitment as the core model, keeping tire selection straightforward. That makes the process less about sorting through multiple sizes and more about confirming the 15-inch wheel setup and choosing a tire that suits the car's intended street use.
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
Owners of a 1993 Audi 100 Quattro usually want quick answers on the correct 195/65R15 size, 15-inch rim fitment, tire selection, and what to inspect before putting a well-kept Quattro back on the road.
Tire Size & Fitment
What tire size fits a 1993 Audi 100 Quattro?
The 1993 Audi 100 Quattro uses a 195/65R15 tire size in radial construction. That is the primary fitment for this model and it uses a 15-inch rim, which keeps size selection much simpler than on vehicles that had multiple factory tire options.
The key next step is confirming that the car still has the correct 15-inch wheels and has not been changed to a different wheel package over the years. A tire with the right size marking still needs to match the actual wheel and leave proper clearance at the suspension and body.
What size rim does a 1993 Audi 100 Quattro use?
The 1993 Audi 100 Quattro uses a 15-inch rim with its 195/65R15 tire fitment. In tire sizing language, the final number in 195/65R15 is the wheel diameter, so the tire is built for a 15-inch rim rather than a 14-inch or 16-inch wheel.
Wheel diameter should be confirmed before ordering tires, especially on a used Quattro that may have seen aftermarket wheel changes. It also helps to verify wheel width and overall condition, since a tire can carry the correct diameter but still be a poor match if the wheel setup has been altered.
Does the 1993 Audi 100 Quattro CS use the same tire size?
Yes. The 1993 Audi 100 Quattro CS uses the same 195/65R15 radial tire size as the main 1993 Audi 100 Quattro fitment. That means owners of the CS are not sorting through a separate original tire size within this covered application.
Even with shared fitment, it is still worth checking the actual wheels on the car before replacement. A Quattro CS that has been modified, fitted with different wheels, or sitting on worn suspension parts may need extra clearance and condition checks before a new set of 195/65R15 tires goes into service.
Choosing the Right Tire
What should I consider when choosing a 195/65R15 tire for a 1993 Audi 100 Quattro?
Start with the correct primary size, which is 195/65R15 radial on a 15-inch rim. Since there is only one main fitment here, the choice is less about decoding multiple factory sizes and more about selecting a tire that suits the car's intended road use and current wheel setup.
A careful selection should also take the car's condition into account. Check that the wheels are the proper diameter, the suspension is in good shape, and there is no unusual wear pattern pointing to alignment issues, because even the correct size will perform poorly if the surrounding setup needs attention.
How do I choose between the available 195/65R15 tires for a 1993 Audi 100 Quattro?
Use the 195/65R15 size as the non-negotiable starting point, then compare tires by overall fitment suitability for a 15-inch wheel and the kind of driving the car actually sees. A regularly driven Quattro sedan and a low-mile collector car may call for different priorities even within the same size.
It helps to look beyond the size marking alone and consider the age of the current tires, the car's ride expectations, and whether the wheels are original or aftermarket. Choosing carefully at that stage keeps the tire decision aligned with the vehicle's road manners rather than treating every 195/65R15 tire as interchangeable.
What rim-fitment details matter when choosing 1993 Audi 100 Quattro tires?
For the 1993 Audi 100 Quattro, the most important rim-fitment detail is the 15-inch wheel diameter required by the 195/65R15 size. That diameter must match exactly, because the tire bead is designed for a 15-inch rim and cannot be safely used on another wheel diameter.
Beyond diameter, the actual wheel setup on the car still matters. A Quattro with replacement wheels should be checked for width, offset, and clearance at the strut, fender, and steering components so the correct tire size can operate properly without rubbing or other fitment surprises.
Restoration & Appearance
Which tire should I choose for a period-style 1993 Audi 100 Quattro?
A period-style approach for a 1993 Audi 100 Quattro starts with staying in the correct 195/65R15 radial size on a 15-inch wheel. Because this is a more modern early 1990s fitment, the goal is usually to preserve the car's proper stance and road-going character rather than recreate an earlier vintage tire look.
Appearance still matters on a clean Audi sedan, so the best approach is to keep the sizing and proportions appropriate to the car. Owners pursuing higher-level originality should also compare any replacement choice with marque-specific historical references and the actual wheel setup on the vehicle before finalizing a set.
Does correct tire fitment matter for a 1993 Audi 100 Quattro restoration?
Yes, correct tire fitment matters because the tire size has a strong effect on stance, wheel-well appearance, and the overall presentation of the 1993 Audi 100 Quattro. Using the proper 195/65R15 radial size helps maintain the look and proportions that suit this generation of Audi sedan.
Fitment also affects how convincingly the finished car comes together as a restoration-oriented project. A mismatched wheel diameter or noticeably different tire profile can change the visual balance, so careful owners usually verify the wheel package first and treat tire size as part of the restoration details, not an afterthought.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 Audi 100 Quattro?
Yes. Modifications can change how a 195/65R15 tire fits on a 1993 Audi 100 Quattro, even when the size itself is correct for the original application. Aftermarket wheels, altered offset, suspension changes, or ride-height changes can all affect clearance at the fenders, struts, and steering components.
That is why a modified car should be checked as an individual setup rather than assumed to behave like a stock example. Verifying wheel diameter, wheel width, and clearance through the full steering range helps prevent rubbing issues and keeps the tire choice tied to the car's actual configuration.
What should I inspect before driving a 1993 Audi 100 Quattro on new tires?
Before driving on new tires, inspect the wheels for damage, confirm the 15-inch wheel diameter, and make sure the suspension and steering components are in sound condition. It is also wise to check alignment, valve stems, and any uneven wear pattern on the old tires that might point to a mechanical issue.
A fresh set of tires cannot correct worn tie-rod ends, weak shocks, bent wheels, or poor alignment on its own. Looking over the car first helps the new 195/65R15 tires wear evenly and lets the Audi deliver the stable road manners owners expect from a well-sorted Quattro sedan.
How often should tires on a 1993 Audi 100 Quattro be inspected?
Tires on a 1993 Audi 100 Quattro should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Collector-era and low-use cars can develop aging issues such as cracking, flat spotting, or slow air loss even when the tread still appears usable.
A good routine is to check pressure, tread condition, and sidewalls before longer drives and to look the tires over periodically during storage. Paying attention to age, cuts, bulges, and uneven wear is just as important as watching tread depth, because older tires can deteriorate long before they look worn out.
