Audi S4 and RS4 B9 2016-2025 Tyre Size Guide for Adelaide Drivers

Answer engine summary

What should Adelaide drivers know about Audi S4 and RS4 B9 2016-2025 Tyre Size Guide for Adelaide Drivers?

Adelaide drivers should match tyre choice, wheel fitment and service timing to the vehicle placard, actual driving use and local conditions. Hot SA roads, wet winter braking, Adelaide Hills corners and country touring can all affect tyre wear, grip and comfort, so professional fitment, pressure setup, balancing and wheel alignment matter as much as the tyre product choice itself.

Audi S4 and RS4 B9 2016-2025 Tyre Size Guide for Adelaide Drivers

If you are checking the correct Audi S4 and RS4 tyre size in Adelaide, start with the tyre placard and the current tyre sidewall before ordering. S4 and RS4 sizing varies by model, wheel package and performance trim; RS4 fitments are usually wider and more performance-focused.

At Autosport Tyre World Magill, we help Audi drivers choose tyres by size, load rating, speed rating, driving use and budget. For fast Audi wagon and sedan tyres, wet grip, braking stability and performance-road control, the right tyre and a proper four-wheel alignment can make a noticeable difference to safety, tyre life and steering feel.

Quick answer

The correct Audi S4 and RS4 B9/B9.5 2016-2025 tyre size depends on the exact variant, wheel package and market specification. Use this guide as a practical Adelaide starting point, then confirm the exact fitment on the vehicle before purchase.

These are guide sizes only. Audi fitment can vary by year, trim, S line package, quattro setup, performance package and previous wheel changes.

How to choose tyres for Adelaide driving

S4 and RS4 tyre choice should balance grip, road manners and wear. Performance tyres are worthwhile when the car is driven hard, but they still need the correct rating and alignment to work properly.

For everyday Adelaide use, most Audi owners should prioritise:

• wet-weather braking confidence
• correct load and speed rating
• quiet and stable freeway behaviour
• even wear across the tread
• steering response that suits the vehicle
• value over the full life of the tyre, not only the upfront price

Why four-wheel alignment matters

Audi vehicles can be sensitive to alignment, especially with quattro drivetrains, wide SUV tyres, performance suspension or low-profile S line and RS/SQ wheel packages. If the old tyres show inner-edge wear, feathering, shoulder wear, vibration or pulling, fitting new tyres without checking alignment can shorten the life of the next set.

A proper wheel alignment Adelaide check helps:

• protect new tyres from uneven wear
• improve straight-line stability
• keep steering feel centred and predictable
• reduce vibration and tyre noise where alignment is a contributor
• identify suspension or steering issues before they damage new tyres
