I noticed during my build (about five months) that my tires/tyres flat spotted a bit. However, I found once I was out on the road for a day that fixed things.
I have also had the car up on four stands and found that once lowered there appeared no obvious adjustment or settling was evident.
Have you got enough room to move the Cobra forward and back every now and then in your garage..
Would personally hate to have to park and leave my Cobra for any length of time. Guess I'm in an area a bit like Cal.
Sorry don't know much about the Good Year big letter tires/tyres. I have the B. F .Goodrich - TA's x 15" on 10" and 8"'.
