No, you're not. You are correct. As you stated, the Lexus pattern uses a 3 tire rotation scheme on the right side and a 2 tire scheme on the left. Tires on the left side will have more miles. For hypothetical 45k tires (5000 miles per rotation ) the 2 left side tires would have 45k miles each and 3 right side tires would have 30k miles each. For what I see as the correct rotation, the Discount Tire, Tire Rack, and BFG recommended patterns are all in agreement. That's what I'll be using.The difference in the Goodrich and Discount Tire sequence (vs. Lexus) is all five tires progress through both sides of the vehicle.
Lexus keeps the same two tires on the driver side and the same three on the passenger side ... evidently for the full life of the tires.
Here's my thinking:
Say you drive 100k miles on a set of tires -- not likely I know, but round numbers for this example. After 100k miles the two tires on the driver side both have 100k miles on them. However the three tires being rotated on the passenger side each have 66k miles on them (because they are each being used 2/3 of time over 100k miles). So the driver side tires have 33% more miles than passenger side. Am I missing something?
