The 1999 Audi A6 came from a period when Audi was firmly establishing the A6 as a refined midsize luxury sedan with all-weather confidence, understated design, and everyday road manners that still appeal to enthusiasts and well-kept driver owners. For this model year, the 1999 Audi A6 uses a 195/65R15 radial tire on a 15-inch rim, keeping the fitment decision focused and straightforward. Because the primary fitment is already a modern metric radial size, the main choice is less about converting construction and more about selecting the right tire within the proper dimensions. That makes wheel condition, intended driving use, and maintaining the car's balanced ride especially important.
Which Tire Size Is Right for The 1999 Audi A6
The 1999 Audi A6 uses one primary tire size: 195/65R15, a radial tire built for a 15-inch rim. The 1999 Audi A6 Base uses this same size, so the main decision is not which size fits, but which tire best matches the car's condition, wheel setup, and intended road use while staying within the correct fitment.
The size 195/65R15 is a metric radial designation: 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 1999 Audi A6, this format reflects a modern passenger-car tire sizing system rather than an earlier vintage bias-ply convention. The important buying differences within this size usually come down to the tire's overall character, wheel compatibility, and how closely the tire suits a stock versus altered chassis setup. It is the right starting point for preserving the A6's intended proportions and everyday drivability.
Sub-model fitment is straightforward for the 1999 Audi A6 covered here. The Base model uses the same primary tire size, so selection centers on choosing the right tire within that fitment rather than sorting through multiple size combinations.

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 1999 Audi A6 usually want quick answers on the 195/65R15 fitment, 15-inch wheel compatibility, sub-model consistency, and what to inspect before putting a maintained or newly purchased car back on the road.
Tire Size & Fitment
What tire size fits a 1999 Audi A6?
The 1999 Audi A6 uses a 195/65R15 tire size. That is a radial metric size designed for a 15-inch wheel, and it is the primary fitment for this model year covered here.
Using the correct size is only the first step. It is still important to confirm that the car has the proper 15-inch wheels, especially if it has been modified or acquired used, and to compare the condition of the suspension and available clearance before installing new tires.
What size rim does a 1999 Audi A6 use?
The 1999 Audi A6 fitment here is built around a 15-inch rim. That rim diameter matches the 195/65R15 tire size, where the final number in the size code identifies the wheel diameter in inches.
Rim diameter should be confirmed before choosing tires, since a tire meant for a 15-inch wheel cannot be mounted on a different diameter wheel. It also helps to inspect the actual wheel width and condition, particularly on an older vehicle that may have replacement or aftermarket wheels.
Does the 1999 Audi A6 Base use the same tire size?
Yes. The 1999 Audi A6 Base uses the same 195/65R15 radial tire size as the core fitment covered for this model year. That makes the sub-model fitment simple compared with vehicles that split tire sizes across trims.
Even with shared sizing, it is still worth checking the car itself before purchase or installation. Wheel changes, suspension alterations, and long-term wear can affect how a tire sits and performs, so the practical check is the actual wheel and chassis setup rather than the trim name alone.
Choosing the Right Tire
What should I consider when choosing a 195/65R15 tire for a 1999 Audi A6?
Start with the correct size, which is 195/65R15 for the 1999 Audi A6 covered here. Since this is already a modern radial fitment, the key considerations are proper 15-inch wheel compatibility, the condition of the wheels, and choosing a tire that suits how the car will actually be driven.
A regularly used A6 may call for a different emphasis than a low-mileage car kept mostly for occasional drives. It helps to inspect suspension wear, alignment condition, and any signs that the vehicle has been altered, because those factors can influence ride quality, tread wear, and clearance with the chosen tire.
How do I choose between available 195/65R15 tires for a 1999 Audi A6?
The smartest way to compare 195/65R15 tires for a 1999 Audi A6 is to begin with fitment basics, then narrow the choice by the car's use and condition. A tire that suits a carefully maintained driver may not match the priorities of a car that spends long periods parked between short outings.
Focus on the combination of correct dimensions, wheel compatibility, and the overall character you want from the car rather than chasing a generic answer. Ride comfort, steering feel, storage habits, and the condition of the suspension and alignment all influence whether one tire choice will make better sense than another.
What rim-width specifications should I compare when choosing 1999 Audi A6 tires?
Rim width matters because even the correct 195/65R15 tire size needs to be matched to a compatible wheel. The 1999 Audi A6 fitment starts with a 15-inch rim diameter, but width should also be confirmed on the actual wheel before final tire selection.
That check becomes especially important on cars that may have had replacement wheels installed over the years. A wheel that is the right diameter but the wrong width can affect tire shape, handling feel, and clearance, so measuring or verifying the wheel itself is a worthwhile step before mounting new tires.
Restoration & Appearance
Which tire should I choose for a period-style 1999 Audi A6?
For a period-style 1999 Audi A6, the best starting point is the correct 195/65R15 radial size on the proper 15-inch wheel. Because this Audi already uses a modern metric radial fitment, preserving the original visual proportion usually begins with keeping the stock sizing format and overall stance intact.
Appearance on a late-1990s luxury sedan is often tied more to correct dimensions and wheel presentation than to vintage-style sidewall treatments. A careful choice should support the car's understated factory-era look while also respecting wheel condition, suspension height, and the intended use of the vehicle.
Does correct tire fitment matter for a 1999 Audi A6 restoration?
Yes, correct tire fitment matters on a 1999 Audi A6 restoration because tire size strongly affects the car's visual balance and how it sits on its wheels. Staying with the proper 195/65R15 fitment helps preserve the proportions expected from this generation of A6.
A restoration-minded owner should look beyond tread alone and confirm wheel diameter, wheel width, and ride height before selecting tires. Even a clean-looking car can lose its intended appearance if the tire size is off, so proper fitment plays an important role in both presentation and road manners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Audi A6?
Yes, modifications can affect tire fitment on a 1999 Audi A6 even when the nominal tire size remains 195/65R15. Changes to wheel width, wheel offset, suspension height, alignment, or body clearance can alter how a tire fits and behaves on the car.
That is why an owner should verify the actual wheel and chassis setup before mounting new tires. A used A6 may have aftermarket wheels or suspension parts fitted years ago, and those changes can influence clearance at the fenders, steering components, and suspension through normal travel.
What should I inspect before driving a 1999 Audi A6 on new tires?
Before driving a 1999 Audi A6 on new tires, inspect the wheels for damage, confirm the tire size matches the 15-inch rim, and look over the suspension and steering for obvious wear. It also makes sense to check alignment condition and verify that all tires are inflated evenly.
A short road test should be paired with a quick follow-up inspection for rubbing, uneven stance, vibration, or unusual noise. On an older car, fresh tires can reveal issues that worn tires were masking, so treating the first miles as a fitment and condition check is a sensible habit.
How often should tires on a 1999 Audi A6 be inspected?
Tires on a 1999 Audi A6 should be inspected regularly, not just when tread appears worn. A routine visual check for cracking, cuts, bulges, uneven wear, and air loss is important, especially on a vehicle that may sit for extended periods or see seasonal use.
Monthly pressure checks and a closer inspection before longer drives are good practice. Age, storage conditions, and suspension wear can matter as much as mileage on an older Audi, so frequent inspection helps catch problems early and keeps the correct 195/65R15 fitment performing as intended.
