I had 2.5 years on the tires on our 1st TT (X23B) and I worried about the tires constantly as we rumbled down the road. I get a little comfort from the TPM that I bought (Tire Minder). Seems to work well and when we upgraded to a 5th they came with me.
Will it catch a problem (blowout) in time? I'll let you know when I find out. I'm the same way about electrical service, the former TT had a surge suppressor (30amp) and I got one for the new 5th (50amp). Can't say if either has made a difference but I sleep better (at night - not behind the wheel)
