Directional Tire Flip?
 

Quick question...just purchased (4) 245 45 18 achillies atr2 tires from walmart...had toyota mount and balance the tires plus full synthetic oil change for $159...the tires are directional....the back passenger side is the only one that the arrow faces to the rear...did toyota mechanic install that one wrong? Can the tire be flipped and remounted to face forward? Or did walmart send me 1 wrong tire??......the tires feel great and better handling...no rubbing...plenty of room in the wheel well...will send pics when the rain stops. Thanxxx

Go back to the store, get the department manager, point out the shop error; and get it fixed. It might feel fine on a dry road, it sure won’t when you hit water or slushy snow.

Sounds like one of the tires is mounted backwards on the rim. You need to get it fixed otherwise you will get uneven tire wear and handling issues as Tootsall pointed out.

Thanx got it flipped...heres some pics for anybody whos thinkin of 245 45 18 tires as far as clearance...
