2018 Audi Q5 Wheel Interchange

2018 Audi Q5 Wheel Fitment And Interchange Guide

Known OEM Fitment For 2018 Audi Q5

The values below are recorded from at least one 2018 Audi Q5 OEM configuration. Trim, package, brake size, and market can change fitment. If a value is not listed as universal, assume it may vary. Confirm your exact specs using the calculator on this page, your door-jamb tire placard, the owner’s manual, or an Audi parts catalog by VIN.

Seat profile of OEM hardware and torque spec can vary by wheel. If you are not sure, check the owner’s manual or an Audi dealer by VIN.

How To Use The Wheel Interchange Calculator

• Open the calculator on this page. In Wheels from (donor vehicle), select the vehicle you want to source wheels from. In Installed on (your vehicle), confirm 2018 Audi Q5.
• If you are evaluating aftermarket wheels, switch to Custom wheel size and enter the rim diameter, width, and offset the seller provides.
• If you are changing tires, enter a Custom tire size with your desired section width and aspect ratio.
• When you change rim diameter, the calculator will update tire diameter in the comparison so you can track rolling diameter differences.
• Review the comparison numbers displayed. Use them to understand how inner clearance and outer poke change relative to your current setup, and how overall tire diameter compares.
• Aim to keep total tire diameter close to stock for accurate speedometer and ABS behavior. Many owners try to stay within about 3 percent, but always prioritize safe clearance and OEM guidance.
• Before you buy, physically test fit one wheel on front and rear to confirm caliper, barrel, strut, and fender clearance under steering lock and suspension compression.

Fitment Checklist Before You Buy

• Bolt pattern: Must match 5x112.
• Center bore: Vehicle hub is 66.5 mm. If the wheel bore is larger, use hub-centric rings to 66.5 mm. If smaller, do not force fit or machine unless done by a qualified shop.
• Fasteners: Thread size is M14 x 1.5. Verify the correct seat type for your wheel (ball vs cone) and correct bolt length, especially if using spacers. Do not mix seat types.
• Offset and width: Use the calculator to compare inner clearance to the strut and outer position to the fender. Verify both front and rear. Wider wheels may require offset changes.
• Brake clearance: Confirm spoke and barrel clearance over calipers. Some trims have larger brakes. Ask sellers for a brake template or test fit.
• Rolling diameter: Keep the tire diameter close to the OEM size shown on your door placard. Large changes can affect speedometer and driver aids.
• Load rating: Wheel and tire load ratings must meet or exceed the OEM requirement for the Q5.
• TPMS: Confirm sensor type and compatibility. Transfer OEM sensors or use compatible replacements where required by law.
• Spacers: If needed to correct offset, use hub-centric spacers with matching 66.5 mm center bore and proper extended hardware.

Plus Sizing And Common Upgrades

Plus sizing increases wheel diameter and often width while choosing a tire with a lower aspect ratio to keep overall diameter similar. Minus sizing does the opposite for more sidewall, often for winter use. Actual fitment depends on brake size, suspension, and wheel design. Do not assume an upgrade will fit without using the calculator and test fitting.

• Starting point examples you can model in the calculator:
  • If your Q5 has an OEM 19x8.0 ET35 wheel, try evaluating a hypothetical 19x8.5 with an offset adjustment, or a 20 inch option with suitable tire sizing to maintain diameter. This is an example only. Verify all clearances.
  • If you are considering a winter package, you can explore a narrower wheel and tire for better snow traction. Some 2018 Q5 packages used 17 inch tires, but brake clearance varies. Confirm by VIN and test fit.
• Use the calculator to:
  • Keep total tire diameter near your OEM placard value.
  • Balance inner clearance and outer poke when changing width. Half of any width change moves inward and half outward unless you change offset.
  • Check that the new tire’s section width does not contact fender liners at full lock or on compression.

Installation Tips

• Work on a level surface. Chock wheels and use a proper jack and stands rated for your vehicle.
• Clean the hub face and the wheel mounting pad. Remove rust and debris so the wheel seats flat.
• Dry-fit one wheel on the front and rear before mounting tires if possible. Confirm caliper and barrel clearance.
• If using hub-centric rings, install them fully seated in the wheel bore that is larger than 66.5 mm.
• Hand start all lug bolts to avoid cross-threading. Audi typically uses bolts, so a wheel hanger guide pin can help align the wheel.
• Tighten in a star pattern in stages. Apply torque to the value in your owner’s manual. Do not lubricate threads unless OEM procedure specifies it.
• After 50 to 100 miles, recheck torque and inspect for any rubbing under full steering lock and over bumps.
• Set tire pressures to the door placard and initialize TPMS if your system requires it.

FAQs

• What is the bolt pattern on a 2018 Audi Q5

  5x112 is recorded for the 2018 Q5. Verify against your VIN or wheel stampings if unsure.

• What center bore do I need for aftermarket wheels

  The vehicle hub is 66.5 mm. Aftermarket wheels often use a larger bore and require hub-centric rings to 66.5 mm for proper centering.

• What lug hardware does the 2018 Q5 use

  M14 x 1.5 wheel bolts. Seat type and length depend on the wheel. Confirm with the wheel manufacturer and your OEM manual before purchasing hardware.

• Will wheels from another 5x112 vehicle fit my Q5

  Maybe. Bolt pattern is only one factor. You must also match center bore or use rings, confirm offset and width, ensure caliper clearance, and use correct seat type hardware. Use the calculator and test fit.

• Can I run 17 inch wheels

  Some 2018 Q5 packages used 17 inch tires. Brake size and wheel design determine clearance, so verify with the calculator, a brake template, and a physical test fit before buying.

• What offset should I choose for wider wheels

  It depends on how much width you add and your brake and fender clearance. Use the calculator to see inner and outer position changes, then test fit. There is no single offset that fits all trims.

• What tire diameter change is acceptable

  Many installers try to keep within about 3 percent of OEM rolling diameter for speedometer and system behavior. Always prioritize clearance and follow OEM guidance.

• Do I need new TPMS sensors

  Depends on your market and sensor type. If your Q5 uses in-wheel sensors and you are buying new wheels, plan to transfer or purchase compatible sensors. If your system is indirect, follow the reset procedure in the owner’s manual.

• What is the correct torque for the lug bolts

  Refer to the owner’s manual or an Audi dealer for the official torque spec for your VIN. Use a calibrated torque wrench and tighten in a star pattern.
