HI Phil,
I kinda figured that as I have a car I store for the winter and fill the tires to 40 psi to avoid the "flat spots".
And I hope I didn't open a can of worms with that as I have seen that debated before....
? Have felt mine at the 30-40 mph range.
No all the time, usually at slight turns.
makes me think a tire issue....
Oddly enough when I bought mine he had that 45 psi from the dealer...WTF.
Does no one check these out before hand?
I do get the storage high PSI..but damn..not out the door...
