Replace when tread depth reaches 2/32 inch, when sidewall damage is present, or when tires are 6+ years old. Don't wait for a blowout.
Many German luxury cars use staggered tire setups (wider in rear) and run-flat tires. Run-flats cost 30-50% more and can't be rotated front-to-back.
EVs wear tires faster due to instant torque. Budget for replacement every 25,000-35,000 miles.
Subaru AWD systems require all four tires to match in circumference. Replace all four tires at once, or match the tread depth of existing tires within 2/32 inch.
