Audi 8J TTS Wheel & Tire Fitment Guide

Models Covered in This Guide

2009-2014 Audi TT S (8J)

With Audi's legendary Quattro AWD system, the TT S offers a ton of performance in a relatively lightweight package. With the right modifications, these cars can be incredibly quick and competent both on the street and at the track.

Taking into consideration the Quattro AWD system and front-biased weight distribution of the TT S, a rotatable square setup is a must to ensure a neutral handling balance and even tire wear at all four corners. Shedding unsprung weight by downsizing to an 18" wheel will also improve upon the overall handling, braking, and acceleration characteristics of the car.

Our 18x9" ET42 fitment compliments the 8J TT S perfectly for both street and track use. With a 5x112 bolt pattern and a 57.1mm center bore, our VW/Audi-specific wheels provide a complete bolt-on fitment without the need for centering rings, spacers, or hub adapters. Designed with brake clearance as a priority, the 18x9" ET42 can clear the factory brakes, as well as a plethora of aftermarket BBKs with ease.

These fitments are ready-to-bolt-on, typically without any modifications, and provide a meaningful increase in wheel width over stock. Available in both 17" and 18" diameters, the fitments listed in this section are an ideal choice for the enthusiast who regularly drives their Audi on the street but still wants to participate in a few HPDE's as well. These fitments are a great match for a completely stock or lightly modified TT S.

Whether you are a casual weekend track warrior that still enjoys your car on the street, or a hard core racer competing for a spot on the podium, negative camber is a vital part of chassis setup that has many benefits. Not only will adding negative camber create more room for wider wheel and tire configurations, it more importantly improves handling, turn-in and tire longevity.
