My 5 year old tires had 5/32 in the rear and 7/32 in front. The rears could maybe have gone another summer and I definitely could have kept the fronts, but decided to replace them all at the same time. Note: I also have a set of drag radials for the track or rears would be toast. I was surprised for a couple of minutes when I thought the old set lasted 38K miles. The car has 38K since I bought the last set, but I drive it year round and have a separate set of winter tires. In anyone in the Ohio/Xichigan area needs an emergency set of front tires let me know.
