SILVER Star
I experimented with rotating 5 tires on my FJ62 and other vehicles. I did not like the tread wear and now do only 4. I do have a new matching tire as a spare and when I replace the 4 on the ground it will go on the ground and a brand new one as spare. That way it does not age out. This assumes you like your tire choice and do not plan on changing.
