2018 Audi TT RS Wheel Fitment Guide

This page lists the known OEM wheel and tire specs for the 2018 Audi TT RS and explains how to use the on-page calculator to evaluate alternate wheel and tire setups. Values that are not provided here can vary by trim and market. Always confirm critical specs with the Audi owner’s manual, service information, or your dealer. Use the calculator on this page to compare dimensions before you buy.

How To Use The Wheel And Tire Comparison Calculator

  • Select Installed on as 2018 Audi TT RS.
  • Choose Wheels from to match a donor vehicle or set Custom wheel size if you already have a target size in mind.
  • Adjust rim diameter, width, and offset. The tool will show inner clearance change, outer poke change, and backspacing differences relative to stock.
  • Set Custom tire size. When you change rim diameter, the calculator updates overall tire diameter in the comparison so you can track ride height and speedometer impact.
  • Brake caliper clearance is not guaranteed by dimensional math alone. Always confirm with a physical test fit or a brake template from the wheel manufacturer, especially on the TT RS due to large front brakes.

Fitment Tips Specific To The 2018 Audi TT RS

Hub bore and centering. The car’s hub is 57.1 mm. Wheels with a larger center bore can be used with 57.1 hub-centric rings. Wheels with a smaller bore will not fit. Use high quality rings and verify the ring lip fully seats in both the wheel and hub.

Bolt pattern and hardware. The car is 5x112 with M14 x 1.5 bolt threads. Audi typically uses wheel bolts rather than nuts. Confirm the correct seat type for your wheels, ball seat vs cone seat, and ensure proper bolt length, especially if spacers are used. Do not mix seat types.

Offset changes. Reducing offset moves the wheel outward and increases fender poke while reducing inner clearance to the fender liner edge is unchanged but inner clearance to the suspension may increase or decrease depending on width. Increasing offset moves the wheel inward and can contact struts or control arms. Use the calculator to visualize inner and outer changes before purchase.

Width changes. Wider wheels add poke on both sides if the offset is unchanged. The calculator will show how much further inboard and outboard the wheel extends compared to the OEM 19x9 ET52 baseline.

Tire sizing. Keep overall diameter close to the factory 245/35R19 to maintain speedometer accuracy, gearing, and ABS behavior. The calculator highlights diameter and sidewall changes. Always maintain at least OEM load index and speed rating or higher.

Spacers and adapters. If spacers are required for clearance, use hub-centric 5x112 spacers with a 57.1 mm center bore. You must use appropriately longer wheel bolts to maintain safe thread engagement. Torque in stages and recheck after a short drive. Adapters that change bolt pattern should be avoided unless engineered for the application and installed by a professional.

TPMS. Sensor type can vary by market. Check your owner’s manual to confirm whether your car uses direct in-wheel sensors or an indirect system that uses ABS data. If direct sensors are required, ensure the new wheels and valve stems are compatible.

Safety Checks Before You Drive

  • Hand spin each wheel after mounting to verify no contact with calipers, knuckles, or liners at full droop.
  • Lower the car and check clearance at full steering lock both directions.
  • Torque wheel bolts to the value in your Audi manual using a calibrated torque wrench. Re-torque after 50 to 100 miles.
  • Verify that the wheel seats fully on the hub and that hub-centric rings, if used, are not deformed or loose.
  • Confirm that center caps do not interfere with axle ends or dust caps.

Common Tools And Helpful Searches

Troubleshooting And Notes

Vibration at speed often points to hub-centric issues or imbalanced assemblies. Confirm that the wheel is truly hub-centric to 57.1 mm and that rings are round and seated. If vibration starts only under braking, inspect rotor runout and wheel seating surfaces for debris or paint.

Brake clearance. The TT RS has large multi-piston front calipers. Even when diameter, width, and offset look acceptable in the calculator, spoke design can still contact the caliper. Obtain a printable caliper template from the wheel manufacturer or test fit before mounting tires.

If you are uncertain about any dimension not listed above, consult Audi parts catalogs, a dealer, or the factory service manual. The calculator on wheelinterchange.com helps you compare what you have to what you are considering, but it does not replace physical verification.

Methodology and sources

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:

  • Bolt pattern / PCD
  • Center bore direction (donor wheel bore must not be smaller than the hub)
  • Wheel diameter, width, and offset against known OEM ranges
  • Lug thread / hardware differences (vehicle-side hardware)

A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
