From what I am reading with the frequent bubbles on the sidewalls of the 21 inch tires, I believe that Lucid should temporarily D/C the 21 inch tires and substitute with the 20 inch tires, until such time that the tire manufacturers can come up with a more reliable tire design for the weight of the car.
When I read that a number of owners are afraid to take their car on a long road trip, because of fear of a tire failure, then its time for reevaluation..
Yes, I know the 19 inch tires are a possible solution, but quite frankly I find them to be very generic looking and many owners want something that looks more appropriate on a expensive great looking Lucid sedan. The 19" wheels look only so so.
I expect to get some backlash on my last statement. But I feel for the money that I paid for the Grand Touring, I expect a nicer looking wheel.(the 20 inch wheels which look very nice were not available when I ordered and received my car).
I love the look of the 21 inch wheels on my AGT, but is seems too many owners are having too many problems with these Pirelli tires.
