2019 Audi TT RS Wheel Interchange

2019 Audi TT RS Wheel Fitment Guide

This page helps you swap or upgrade wheels on a 2019 Audi TT RS without rubbing, vibration, or hardware issues. The problem most owners hit is balancing brake clearance, fender space, and hardware match under real road loads. We will move from constraints to a verified setup using the on-page calculator.

1. Goal

Choose wheels and tires that fit the 2019 TT RS safely, match hardware, and keep handling and speedometer behavior within acceptable limits.

2. Prerequisites

• Know your OEM baseline to compare against.
• Measure your car for clearance if brakes or suspension are modified.
• Have basic tools for validation and install.

Notes from practice:

• TT RS front brakes are large. Spoke-to-caliper clearance is a primary constraint.
• M14 x 1.5 hardware is required. Seat type and bolt length must match the wheel. Audi OEM is often ball seat, but this can vary by wheel. Verify on your existing wheels or with OEM documentation.
• Center bore is 57.1 mm. Aftermarket wheels with larger bores need hub-centric rings sized to 57.1 mm on the car side.

Helpful tools:

• Torque wrench 1/2 inch
• Wheel hanger guide pin M14x1.5
• Hub-centric rings 57.1 mm

3. Step by step

3.1 Set your baseline in the calculator

• Open the calculator on wheelinterchange.com.
• Set Installed on (your vehicle) to 2019 Audi TT RS.
• Confirm the OEM wheel and tire show as 19 x 9.0 ET52 with 245/35R19.

3.2 Compare a donor wheel or custom size

• If using wheels from another vehicle, choose that in Wheels from (donor vehicle). The tool will load the donor specs.
• Or use Custom wheel size to enter rim diameter, width, and offset. Use Custom tire size for section width and aspect ratio.
• Changing rim diameter updates tire diameter in the comparison, so watch the rolling diameter change.

3.3 Apply constraints and trade-offs

• Offset trade-off: Lower ET pushes outward and risks fender rub. Higher ET tucks inward and risks strut or liner contact.
• Width trade-off: Wider wheels add inboard and outboard poke. Use the calculator’s inner and outer position deltas to maintain clearance similar to OEM.
• Brake clearance: Maintain at least about 3 mm spoke-to-caliper clearance. More is recommended for heat and flex.
• Rolling diameter: Keep total tire diameter within about ±3 percent of OEM for speedometer and ABS behavior.
• Hardware: Keep 5x112 pattern and M14 x 1.5 bolt threads. Match seat type and ensure proper bolt length engagement.
• Centering: If wheel bore is larger than 57.1 mm, plan for hub-centric rings.

3.4 Select tires for the wheel

• Use the calculator to see recommended tire widths per wheel width and to check sidewall shape assumptions.
• Watch the “poke” and “inset” changes as you adjust section width and aspect ratio.
• Confirm the load index meets or exceeds OEM rating.

4. Validation

Before buying, validate on paper and with measurements. Before driving, validate on the car.

• Paper check in the calculator: Ensure inner clearance change is not more inboard than OEM by more than your measured strut gap. Ensure outer change does not exceed fender space.
• Measure on the car: With OEM wheels on, measure from tire shoulder to fender lip and from inner tire to strut at the tightest point. Use these as your clearance limits.
• Brake template: If available from the wheel maker, overlay their caliper template to confirm spoke clearance.
• Test fit one wheel without the tire: Spin by hand and check caliper, knuckle, and liner clearance.
• Mount and torque: Install hardware hand tight, then torque in a star pattern to the Audi-specified value in the owner’s manual.
• Road test: Low-speed steering lock to lock. Hit bumps while turning. Listen for rub. Re-torque after 50–100 miles.

5. Troubleshooting

• Vibration at speed: Confirm hub-centric fit. Add proper 57.1 mm rings if the wheel bore is larger. Recheck balance and torque.
• Rubbing on turns or bumps: Compare your outer position delta to OEM in the calculator. Raise offset or reduce width or tire section width. Check liner clips and fender screw points.
• Inner contact or scraping: Your inner clearance went negative vs OEM. Increase offset or narrow the wheel. Verify strut perch and knuckle clearances at full droop and compression.
• Bolts bottoming or short engagement: Confirm M14 x 1.5, correct seat type, and length. You should achieve safe thread engagement. Do not stack spacers without longer bolts designed for the total stack.
• TPMS or speed error: If tire diameter changed beyond about ±3 percent, recalibrate if possible or choose a closer overall diameter.
• Brake interference: Spokes or barrel hitting calipers means offset or spoke design is incompatible. Use a wheel with more concavity or verified brake clearance. A thin spacer can help, but confirm fender space and bolt length first.

6. Wrap up

The 2019 Audi TT RS responds well to careful wheel and tire changes, but the brakes and tight arches set clear constraints. Use the calculator on wheelinterchange.com to compare inner and outer position, brake clearance assumptions, and tire diameter against the OEM 19 x 9.0 ET52 with 245/35R19. Match 5x112, M14 x 1.5 hardware, and a 57.1 mm hub interface. Validate with measurements, a controlled test fit, and proper torque. If a value is unclear or varies by trim or market, confirm it with the on-page calculator data and OEM sources before purchase. With these checks, you move from guesswork to a confident, rub-free install.
