? ? ? Why just the tire seller. Would not any installer be similarly put at risk ?Yup, Costco does the same thing here in Canada. They can only mount tires that is listed on the car doors. They are covering their asses because probably some dufus had them place a different sized tire in the past, got in an accident and sued them.
I don't blame them.
You can purchase the tires from them and have them mounted somewhere else. It's simple.
Supposedly the info on the door is what makes the tire shop liable regarding the wrong size tire - this being the case the only way the fix-it shop could plead ignorance would be if you brought the car in without the door - if this is obvious to us then any dirt-bag lawyer could just as easily file suit on the same basis -The tire shop would be knowingly selling and mounting the wrong sized tire -- and could be held liable. The fix-it shop would just be doing what the customer asked -- and could plead ignorance if it came down to it.
Lot of these shop's around here too, ( Phoenix )You obviously don't have many fly-by-night Mexican tire shops in your area. Around here, if they can squeeze it on the rim, they'll mount it. Lots of folks buy tires off Tire Rack or FleaBay and take 'em to the Mexican tire shops because they'll mount and balance for $5-10 a wheel on the car.
False, a common misconception. If the tires are inflated equally, the footprint is exactly the same area (square inches or square cm). Think of the meaning of PSI as "pounds per square inch" and you'll get it. Roughly 3000 pounds with driver and gear, divided by 4 is 750 pounds per tire, divided by 33 psi is 22.7 square inches per tire. Consider weight distribution and perhaps the front tires have more like 27 square inches and the rears 18 square inches, but you get the point.Since wider tires do not have same traction per sq. in. of
