Agree! That means Pirelli is not ready to support so heavy Lucid Air. Maybe no one is ready to. If so, Lucid needs to recall this kind of weel and tires. However, Lucid even didn't take care of warranty. I have to pay full amount in front to the mobile service.
There have been enough reports from others of bulges on the Pirelli LM1's to indicate there is an engineering/manufacturing problem with this tire. A bulge should definitely be covered by the tire warranty, but the tire warranty is issued by the manufacturer, not by Lucid. Have you pursued a warranty claim with Pirelli?
However, the slit on the sidewall you pictured would seem to be the result of curbing the wheel, and that would not normally be covered by manufacturers warranty. (This is why retailer warranties such as Tire Rack provides can be helpful.)
Building tires for EVs is new ground for the manufacturers that are attempting it. All tire design involves balancing competing demands. Higher grip usually means shorter tread life. Run-flat capability usually means stiffer sidewalls and a harsher ride. Low rolling resistance can mean less precise handling. Optimizing tread design for water dispersion can mean higher trie noise.
Etc.
EVs up the ante. They are heavier than ICE cars, they produce more torque at the wheels, their weight increases braking demands on the tire, range imperatives dictate lower rolling resistance. The lack of drivetrain noise accentuates the presence of tire noise in the cabin, so sound suppression becomes another heightened demand. On top of all this, the handling aims and the suspension sophistication of the Lucid require a tire with especially responsive handling dynamics.
We have had eight Pirelli LM1 21" tires on our Lucid, and we have been lucky in not encountering the bulging issue. We replaced both rear tires when one of them picked up a sheet metal screw in the road. We replaced both front tires due to a blowout on the right tire at about 50 mph caused by hitting a piece of metal in the road as we passed a large construction site. While the tire lost pressure instantly, we were able to brake safely and drive the car about a mile until we could make a U-turn to get to a service station with a safe place to park. (This happened on a curbed 6-lane roadway with no pull-off shoulder.) To my astonishment, the deflated tire protected the rim, which had no damage at all.
While I am worried about the reports of bulging on the LM1, my own experience is that the tire meets the challenging demands put on its design. It's reasonably quiet, it has very good grip in the wet and the dry, it stays planted under hard acceleration and brakes aggressively with good control, it handles the prodigious torque our Dream P puts down under my heavy foot, and its tread wear is not bad given the fairly skinny rubber for a car of the Lucid's weight and power.
! However, I've only driven that car 4 times and parked in private garage since the new tires replaced last month. I even don't remember any hitting event happened. Maybe the tire has good silence feature
. Just now, I checked other tires and find a bulge on the rear-left tire, which is a new tire changed last month too. Isn't it a quality issue? Do you think that should be covered by a warranty?
