In my “Tire Replacement Strategy?” thread I got varying answers as to whether to replace 2 or all 4 (original) tires on my 2007 Yaris.
I ended up replacing all 4 tires. The rear tires looked as though they still had almost as much tread as they did when they were new but the front tires were one step away from being bald.
I know I said in my other post that there was no cracking and the rear tires looked great - but I took a much closer look at the tires and could see fine hairline cracks in the sidewall and around some of the tread. There were so many of those cracks that it looked like a chunk could possibly fly off if I were to hit a pothole - and eventually maybe even without hitting anything. I didn’t see any of this when I first looked because I wasn’t up as close as I needed to be.
The tires (RE92 Bridgestones) are at least 7 years old and my car is kept outside - although the climate is very moderate here in Redwood City CA.
The shop that was recommended by tirerack and here at cartalk put the new (General Altimax RT43) tires on in about 40 minutes. I immediately experienced a smoother and quieter ride and the handling seems a slightly better than before.
In closing, thanks for all of the good advice and I have one more question. The tires are supposed to be inflated to 32 PSI according to the manual and the template on the door. I checked each tire after getting home (and letting it sit for a couple hours) and each tire was set at 28 PSI. It is no big deal to me and very simple to correct but I still wonder why they did that. I think I’ve written here before that I’ve never bought new tires that had the recommended inflation - ever!
Is there some logic in that? Is a difference of 4 PSI statistically insignificant? : ) I know some people keep their tires over inflated or under inflated for reasons that make sense to them but I’m just curious why the shop wouldn’t follow the template inside the door.
I know I could ask them why they did what they did but I prefer right now to hear the opinions of people here.
Thanks in advance for any comments.
