I rotate regularly using the rotation pattern given in my owner's manual. Drive wheels go straight to the other end and non-drive wheels also go straight to the other end. I checked a 2012 Tundra owners manual and it shows the same recommended rotation pattern as for the Sequoia. No "X" for any wheels.
Can anyone explain why the tires should or should not be rotated with an X pattern. The owner's manual for every car and truck I have owned since radial tires came out have recommended the same straight front-to-back pattern; no "X" for any wheels.
Is the front-to-rear (without X) rotation pattern given in the owner's manual simply over-conservative to cover the case where someone might mount directional tires? If not using directional tires, is it better to ignore the owner's manual and use Big Shasta's rotation pattern?...
Huh. You are correct...page 426 of the 2017 Tundra owner's manual DOES show only front/back on the same side. That's the first time I ever remember seeing that recommended.
This new Tundra is my first new Toyota in a long time, simply because the last one lasted a very long time. I could have checked the Toyota Repair Manual on my 86 4Runner, but it went with the truck to the new owner...sold for classic money. My "other" car company experience has been the opposite of yours.
All cars in-between my Toyota cars have been those made by Big Three companies that start with a "G", or an "F", but will remained unmentioned to avoid an avalanche of childish red thumbs.
The latest model is a 2008 of "G" persuasion, and the owner manual shows moving front drive wheels straight to the rear, and "Xing" the rear tires to the front. Aren't tires essentially the same today as they were in 2008? The next latest model was a 2006 American sports car of the longest production history...no rotation on that one; all four tires were directional, and the rears were much larger than the fronts, which were pretty huge.
As to why present-day rotation pattern SHOULD be different than for the old bias tires, I was told long ago that the direction of rotation, and therefore the mounting sides, should not be changed with steel-belted radial tires. I have no idea if that changed with the movement from steel to fiber belts. Toyota's recommendation executes that steel-belted tire protocol to the letter; other car companies and tire authorities now seem to think it's not that critical.
If it makes no difference to today's fiber-belted tires, then I suspect the recommendation of "other" car companies does equalize the wear a little better, since all tires will eventually be in all four locations. I don't know myself, but it's probably better to stick with the OEM recommendation; Toyota's is certainly easier.
