We just took delivery of our Grand Touring with 21" wheels this weekend. We were looking at the treads on the tires and were shocked at how shallow they are, which got us to looking into the tires and the warranty on the tires - which was hard to find as it appears that the tires have no warranty at all. And the reviews of the Pirelli 21" are pretty dismal - expensive tire that wears out very quickly - as in like 10,000 miles, which is like once a year! We were excited for a minute that both goodyear and michelin were coming out this year with EV tires that looked to be more durable, but still made for EV's and their special needs. Sadly they are not making 21! I am seriously thinking of swapping to 19" - has anyone done this? What is involved with making that kind of change? We just thought the 21 looked much better, we had no clue the tires would be a major maintenance item every year. And no spare of any kind for the Lucid either! What are people doing when they get a flat? Just towing it?
