Tire age

i tend to follow mfgr's recommendation on tires, which some list 6yrs and others 10yrs as maximum service life. i'll go for 10 but if i'm having traction problems at 6 years, then so be it.

if you're experiencing loss of traction, then regardless of them passing the eye test i'd be fibbing if i didn't say you should be looking for new donuts.

think about the cost of new shoes for your baby vs what your insurance deductible is if, in the unfortunate event, you broke traction randomly and slammed into a curb or another car.

at speed i lost the tread on a left rear that was just past its sell by date, mercifully my wheel lip trim was spared and besides the code brown in my pants i was fortunate that nothing else of note happened.
