Where to Find the Correct Tyre Size for Your Q5

Because of the variety of factory configurations and the possibility of wheel changes by previous owners, the most reliable tyre size reference is always the vehicle itself. Audi provides clear, model-specific guidance on each car.

Checking the Tyre Sidewall

The simplest way to confirm what is currently fitted is to read the information printed directly on the tyre sidewall. This shows the complete size, load index, and speed rating.

The following ordered list explains how to read and interpret a typical tyre-size marking for a 2013 Audi Q5.

1. Locate the code – Look for a sequence like 235/60 R18 103V on the tyre sidewall.
2. Read the width – The first number (235) is the tyre width in millimetres.
3. Check the aspect ratio – The second number (60) is the sidewall height as a percentage of the width.
4. Identify construction and rim size – The letter (R for radial) is followed by the wheel diameter in inches (18).
5. Note load and speed ratings – The following number and letter (e.g., 103V) indicate how much weight the tyre can carry and the maximum rated speed.

Reading the sidewall ensures you know not only the physical dimensions but also whether the tyre’s load and speed capabilities are appropriate for the Q5’s weight and performance.

Using the Door-Jamb Sticker and Owner’s Manual

For a definitive reference to Audi’s approved tyre sizes and pressures, drivers should consult the vehicle’s official documentation and labels. These sources detail both factory-standard and alternative approved fitments.

The unordered list below describes where to find these references and what information they typically provide.

• Driver’s door-jamb label – Usually a sticker on the driver’s side B-pillar, listing recommended tyre sizes and cold tyre pressures for front and rear axles.
• Fuel-filler flap label (in some markets) – May repeat or supplement tyre pressure and size guidance.
• Owner’s manual – Contains a dedicated section outlining standard and optional wheel and tyre combinations, including notes on winter tyres.
• Service or build-sheet records – On dealer printouts or digital records, often showing the car’s original wheel and tyre specification (useful when wheels have been changed).
• Manufacturer or dealer website – VIN-based lookup tools can sometimes confirm the factory wheel and tyre option originally installed.

Checking these official references helps ensure that replacement tyres match Audi’s technical recommendations, preserving safety, legality and performance.

Why the Correct Tyre Size Matters

Tyres are a critical safety component, and fitting the wrong size on a 2013 Audi Q5 can affect handling, braking, fuel economy and even legal compliance. In a vehicle with all-wheel drive like the Q5, tyre sizing consistency is especially important.

Impact on Handling, Braking and Quattro System

The Audi Q5’s suspension, steering and electronic systems are tuned for specific rolling diameters and load capacities. Deviations from the recommended size can disturb this calibration, particularly on quattro all-wheel-drive models.

The following list summarises key reasons to adhere closely to Audi’s specified or approved-equivalent tyre sizes.

• All-wheel-drive integrity – Mismatched rolling diameters front to rear can stress the quattro drivetrain, leading to binding or premature wear.
• Handling balance – Incorrect sizes can alter ride height and suspension geometry, changing understeer/oversteer characteristics.
• Braking performance – Tyres outside recommended specifications may lengthen stopping distances or affect ABS and stability-control calibration.
• Speedometer and odometer accuracy – Large changes in rolling circumference make the speedometer read too high or low.
• Legal and insurance implications – In some jurisdictions, non-approved tyre sizes can cause vehicle-inspection issues or complicate insurance claims after accidents.

Keeping tyre size within Audi’s approved range ensures that the Q5’s safety systems and quattro drivetrain function as designed, reducing the risk of mechanical problems or compromised road manners.

Winter, All-Season and Performance Tyre Choices

Many 2013 Audi Q5 owners change tyres seasonally or choose different tyre types while attempting to stay within approved size ranges. Audi typically allows multiple diameter and width combinations as long as overall rolling diameter and load ratings remain appropriate.

The ordered list below outlines typical strategies owners follow when selecting tyre types and sizes for different driving conditions.

1. Winter setup on smaller wheels – Some drivers downsize to 17- or 18-inch wheels (e.g., 235/65 R17 or 235/60 R18) for winter, gaining taller sidewalls and better snow performance.
2. All-season, year-round fitment – Many stick to the factory size such as 235/60 R18 but choose an all-season pattern to avoid seasonal tyre swaps.
3. Summer or performance focus – Enthusiasts with S line or sport packages often choose 19- or 20-inch options like 235/55 R19 or 255/45 R20 with performance-oriented tread designs.
4. Matching load index and speed rating – Regardless of season, owners maintain or exceed the OEM load index and speed rating to keep the vehicle within specification.
5. Consulting tyre professionals – Before departing from factory sizes, drivers check with tyre dealers or Audi specialists to ensure new sizes are compatible with the vehicle.

By selecting tyre types within Audi’s dimensional and load limits, Q5 owners can tailor their vehicles to climate and driving style without undermining safety or mechanical reliability.
