Opinions on this tire tread?

Respectfully, I know ground vehicle tires are not always held to critical standards that aircraft tires are, but this is one of many good references for those that might care. If they were mine, I'd change 'em. YMMV

Just my opinion. I would buy new tires. When I go on a trip or drive at highway speeds I don't want to even have to think about my tires.

 

based on what the OP explained, the tire is OK and should be usable to 8 years, after that there is increased risk. what is the speed rating of this tire?

 

I had some GY Comfortreds on the rear about 90000 miles and maybe it was 5.5 yrs. Tread looked OK but day before I was scheduled to put on new Tire Rack tires was rainy and my wife spun out with a little fender bender. I'd have felt better if I'd had the new tires on there.

 

Probably not a problem if it has been stable for over a year and if you can't see anything but rubber looking into it in good lighting. I'd watch to make sure it doesn't start growing.

 

i looked it up. it's V-rated, excellent. the NHTSA study on tread separation showed that the tire aging problem was mostly limited to south USA (=high temps), low speed rating (=low quality), and some brands (again, low quality).

 

That goes to the carcass. Out of limits.
