Audi A1 Tyre Size: The Complete, No-Nonsense Guide for Every Generation

Understanding the Importance of Choosing the Correct Audi A1 Tyre Size

When we look at the Audi A1, we see a compact premium hatch with personality stirred into every corner. But beneath its polished exterior and confident stance lies one of the most underrated components affecting how it drives: the tyres. We often overlook them—until a warning light flickers on, the tread looks worryingly low, or we’re stuck choosing between mysterious numbers like 195/55 R16 and 215/40 R18.

Selecting the right tyre size for your Audi A1 is more than matching digits; it’s about steering feel, braking distance, fuel efficiency, comfort, and even insurance approval. And because different trims—from Sportback SE to S Line Competition—wear different factory tyre sizes, it’s crucial to get it right. That’s exactly what we break down here, calmly and clearly, like chatting with a friend who knows their stuff.

Audi A1 Tyre Size by Year, Trim, and Wheel Option

Why Tyre Sizes Vary Across Models

Even though the Audi A1 sits in a small footprint, Audi designed distinct personalities depending on the trim. Basic trims lean toward comfort and efficiency, while mid- and high-spec models chase sharper handling with wider tyres and larger alloys. That’s why you’ll find different tyre sizes between SE, Sport, S Line, and the more athletic S Line Competition or Black Edition.

Below, we break down the exact tyre sizes for both generations of the Audi A1.

First Generation Audi A1 (2010–2018) Tyre Sizes

Standard Factory Tyre Sizes (Gen 1)

What These Tyre Sizes Mean When Driving

• 15-inch setup – noticeably more comfortable; ideal for city use and poor roads.
• 16-inch setup – balanced ride, quieter motorway cruising.
• 17-inch setup – sharper steering, firmer suspension feel, sportier dynamics.
• 18-inch setup – maximum grip and aesthetics, but harsher ride and higher cost.

Think of it like choosing footwear: 15-inch is a cushioned running shoe, 18-inch is a stylish but stiff trainer you wouldn’t wear on a long hike.

Second Generation Audi A1 (2019–Present) Tyre Sizes

Factory Tyre Sizes (Gen 2)

How These Sizes Reflect the Driving Character

• 15-inch – focuses on efficiency and comfort.
• 16-inch – widely considered the “sweet spot” for daily use.
• 17-inch – sporty with better responsiveness.
• 18-inch – eye-catching and performance-oriented.
• Citycarver – slightly higher profile for rougher surfaces and extra ride height.

Audi continues the same philosophy from the first-gen: choice, personality, and tailor-made driving feel.

Understanding Tyre Size Numbers (Quick Breakdown)

Let’s decode a typical tyre size: 215/45 R17

• 215 → tyre width in millimetres
• 45 → aspect ratio (height is 45% of width)
• R → radial construction (standard modern tyre type)
• 17 → wheel diameter in inches

Once you understand this, you suddenly see tyre sizes not as random numbers, but as a recipe controlling comfort, grip, and cost.

General Tyre Pressure Ranges (May Vary Slightly)

Always check the sticker on the door frame for exact values. Audi loves precision—and so does your fuel gauge.

OEM Tyre Brands Typically Fitted to the Audi A1

Common Factory-Fitted Brands

• Continental
• Bridgestone
• Pirelli
• Hankook
• Michelin

These brands show up repeatedly in Audi A1 delivery photos and service schedules. Each brings something different to the table:

• Michelin – long life, premium feel
• Continental – superb grip, especially in wet
• Pirelli – sporty handling
• Bridgestone – predictable, reliable performance
• Hankook – efficient and cost-effective

Choosing an OEM-equivalent keeps the handling characteristics closest to Audi’s intent.

Choosing the Best Tyre Size for Your Audi A1 Driving Style

Choose:

• 15-inch
• 16-inch

Higher profile = smoother ride.

If You Want Sportiness

Choose:

• 17-inch
• 18-inch

Lower profile = faster response but firmer feel.

If You Want Versatility

Stick with 16-inch or 17-inch.
They offer the best of both worlds.

Can You Change Tyre Size from Factory?

Common Audi A1 Size Upgrades

Many owners upgrade wheel sizes, especially from:

• 15” → 16”
• 16” → 17”
• 17” → 18”

This is perfectly acceptable as long as you follow the correct rolling diameter range (±2% tolerance). Going too extreme risks:

• speedometer inaccuracy
• suspension stress
• rubbing inside wheel well
• MOT failure or insurance issues

Audi A1 owners commonly retrofit S Line wheels on Sportback SE or Sport trims, gaining a visual upgrade without compromising safety.

Audi A1 Winter Tyre Size Recommendations

Best Sizes for Snow and Ice

Recommended:

• 185/60 R15 (Gen 1)
• 185/65 R15 (Gen 2)

Why? Narrower tyres cut through snow more efficiently, offering better stability and grip.

Best Winter Tyre Picks

• Michelin Alpin
• Continental WinterContact
• Goodyear UltraGrip

Stick to 15” or 16” if you want the best winter performance.

Fuel Economy Differences Between Tyre Sizes

Tyres affect MPG more than you think.

Smaller Tyres (15"–16")

• lower rolling resistance
• lighter weight
• higher MPG

Larger Tyres (17"–18")

• heavier
• increased friction
• slightly reduced MPG

Expect a difference of 1–3 MPG between extremes.

How Tyre Width Affects Audi A1 Grip and Comfort

Wider Tyres (215mm+)

• more grip
• better cornering stability

But:

• heavier steering
• more tyre noise
• higher fuel consumption

Narrower Tyres (185–195mm)

• smoother ride
• improved efficiency
• better snow performance

Choosing width is like balancing strength and agility.

Signs You’re Using the Wrong Tyre Size on Your A1

• Steering feels heavier than usual
• The ride becomes unexpectedly harsh
• MPG drops significantly
• Wheel arch rubbing at full lock
• Speedometer reads incorrectly
• Insurance becomes invalid

The wrong size affects multiple systems—not worth the risk.

How Often Should You Replace Audi A1 Tyres?

General Replacement Intervals

• Every 20,000–35,000 miles for regular tyres
• Every 15,000–25,000 miles for performance tyres
• Every 5–6 years regardless of mileage

Check the DOT code for manufacturing year:

• Example: DOT 3021 = made in week 30 of 2021.

Understanding Load Index and Speed Ratings

Typical Audi A1 Ratings

• Load Index: 84–88
• Speed Rating: H, V, or W

Higher performance trims like S Line usually wear V-rated tyres.
