🔧 Auto & Mechanics · Step 2/7

Wear bars and inner edges

Wear bars and inner edges — step 2 of 7 in Tire Rotation & Pressure. When tread is flush with the wear bars, replace. Inner-edge bald with outer still good is often alignment or camber, not a missed rotation.

FWD vs the rest

FWD vs the rest — step 3 of 7 in Tire Rotation & Pressure. Common FWD: fronts go straight back, rears cross to the front (unless directional). RWD often sends rears straight forward.

Chalk, jack, star torque

Chalk, jack, star torque — step 4 of 7 in Tire Rotation & Pressure. Mark LF RF LR RR. One corner at a time or all four off — just don't lose the plot.

Valve stems

Valve stems — step 5 of 7 in Tire Rotation & Pressure. If you are breaking beads (you shouldn't be for a simple rotation), protect the sensor. For a rotation you are only moving complete wheels.

Write it down and check the spare

Write it down and check the spare — step 6 of 7 in Tire Rotation & Pressure. Date, mileage, pattern. Full-size spare gets PSI too. Donuts have their own high pressure on the sidewall — don't set them to 35 and call…

Book an alignment if the wear is lopsided

Book an alignment if the wear is lopsided — step 7 of 7 in Tire Rotation & Pressure. Rotation equalizes wear that is already even-ish. It does not repair a car that eats the inside of the fronts every 8,000 km.
