- My understanding on this comes from working in a tire shop and some racing
- experiences too. Some tires (mostly really high performance) are unidirectional
- and thus cannot be switched from side to side. Others are asymmetric and
- cannot be rotated without following the manufacturers directions.
- Most however are free. I believe that early radials had big problems with
- having their direction changed (ie, lefts to right), but that now this is
- not a consideration.
- Some people I have spoken to about this claim to have had vibration problems
- from switching sides with tires, but personally I have never had any problems.
- I always keep tires in pairs and rotate sets.
- Thus rears become fronts and fronts rears. Or lefts become rights and rights
- lefts. Or both, left front to right rear, right rear to left front. And when I
- worked in the tire shop, I also rotated the tire on the rim, so that the inside
- became the outside. This allowed for much longer life of tires with the outer
- edge worn off due to hard cornering, but gave some problems with vibrations and
- strange resulting wear.
- I would suggest that for a Tercel, front to back is enough, and easy to do.
- The rears should greatly outlast the fronts, so you could do like my sister
- and use two sets of fronts and one set of rears in the same amount of time
- and no rotation, or like me and rotate quite frequently and get perhaps 10%
- more distance out of the 4 than the much simpler 'no rotation' method allows
- for.
- If any wear shows up on one set of tires (left or front), rotate them off that
- side/end.
