I measured them today with a gauge. I get 6/32 on them. So that leaves plenty of tread/life on the tires.
I almost never get up to STC. Sorry, if you want them I can meet you somewhere. Plymouth? Maple Grove?
After a better examination today. The tires actually range from about 5/32 to 6/32. Mostly even wear. Price is changing to $40.
My buddy built a bubble balancer and uses a manual tire changer he got from Northern Tool. Works pretty well. He's been doing his own tires for 2-3 years now.
