Seventeen years without a blowout is a good run. Thanks for the reminder to us not to procrastinate on important things like tires.
I'm seven years with no blowouts but I'm only averaging 1,000 miles a year (a lot of local camping) and don't drive over 60 mph (yea, I'm that guy) so not a lot of wear and tear on the tires as far as mileage goes. The TT is also stored where it doesn't get a lot of direct sunlight which probably helps preserve the tires.
Hopefully your next 17 years will be blowout free.
