Wow those tires are toast!Replaced another bad tire! Started hearing the rhythmic sound again yesterday, but this time the intensity increased rapidly! I was 15 miles from home, so turned off highway, used back roads and slowed down. Last tire was on right rear, this time left rear, same age and condition.
I think there 2 or 3 causal factors here. The tires were old and well worn, this one was made mid 2011. It has been pretty warm here recently, temps in upper 90F range. Lastly I bumped pressures up to 60psi or so 2 months ago. Looks like old tires don't like that!
I think it may be time to break down and spend some money on NEW tires, not just new to me!😆 View attachment 86292
eBay! The quality is pretty good, although one thing that irks me is the stitching only goes down three sides, not four like it should based on the design. Hey, it was only like $10 though so not bad.
Yes, LIKE my avatar, I stole that pic from the net as I didn't have a better one. I could always use my Googlle Street View one:Good work. Is it a citrus like your avatar?
