@Neurio. I would to, but I am no longer having nightmares about my 21" Pirellis. As
@Bobby @borski and others have said, they have tens of thousands of miles with 21 and never a bulge. On my OEM Pirellis, I now have 4k of fast rough highway and Colorado back roads. I have smacked potholes. No issues.
I dare say driving style plays a role. While I only have anecdotal proof, in my heart of hearts and racing experience, I am convinced tire pressure plays a role in these Pirelli issues. I believe Lucid recommended 42 is too low. And if you set at 42, you are immediately loosing air below 42.
I run 45 or 46, cold, measure early AM, with a good gauge. The TPMS sensor is +- 3psi. Not consistent. For a tire to develop a sidewall bulge, it must have hit something that causes the sidewall to fold over so much that the side plies separate. It's the air in your tire that holds the car up. The less psi, the less pressure and air volume to hold up.
In SCCA racing we would try, for fun, putting the tires at max AP. The car rode like hell, but tires ran cool and never ever suffered internal damage. And then we lowered slowly. Many here will tell you TP is always a compromise, usually between comfort and heat and rolling resistance. And now with our low profile tires and heavy steamroller Lucids and shitty roads, the chance of inner sidewall ply separation.
And, your 20s are still low profile. Keep your chin and tire pressure up! And EVEN withour Lucid 19s, with a big 45 ratio,Lucid requires 49 PSI!!! That should tell you something about Lucids thoughts on TP.
