https://www.lucidupdates.com FAQ section:
Some 21" wheel owners have had sidewall bulges and tears due to road hazard and have opined that other tire brands may be more resilient. Some have suggested fitting Michelin PS4 tires to the vehicle.
Regarding tire bulges and blowouts: neither Lucid nor Pirelli will warranty against road hazards. It is highly recommended to purchase an aftermarket warranty from Discount Tire/America's Tire. COst is about $60 per tire. Some have also secured aftermarket roadside assistance for this.
Below is information about 21” tire load rating (older system) and load index (newer and more specific, see link below for more information on these).
Pirelli (approved by Lucid)
Load rating: XL
Front load index: 99 (1709lb per side = 3418lb)
Rear load index: 103 (1929lb per side = 3858lb)
Total load rating: 7276lb
Michelin PS4
Front load index: 96 (1565lb per side = 3130lb)
Rear load index: 101 (1819lb per side = 3638lb)
Total load index: 6768lb
Vehicle weight is 5236lb so:
-Pirellis allow for 2040lb of passengers and cargo.
-Michelins allow for 1532lb of passengers and cargo.
The 20" tires on the Touring are Michelin PS EV which are load index 99. This tire is not available in the 21" size for Lucid.
