Obese Passenger and Tire Blowout

So I am currently sitting waiting for the tow truck to come and pick up my car to take to RimTyme to get a new tire, as they are the only ones that carry said size, and am beginning to connect the dots. I am driving on lowered suspension (coilovers) and just have the tires slightly tucked. Today while riding on the interstate with my coworker who is a HEFTY 450 +/- lbs of solid muscle/fat (think sumo build) for the first time ever, I happen to get a random tire blowout on the front passenger side. Needless to say I think he knows the real reason behind it but 1. I’m not an insensitive pos and 2. I did have the choice to ride in his vehicle so I’m not going to “place blame” out loud. In the third image you can see where there is a clear slice through the tire at the top (I’m assuming from the weight causing the undercarriage to dip and cut the tire going over any bumps/holes). I’d just like you all’s input on what you think?

Edit: Praying to the good Lord above that there is no wheel bend/suspension damage, as either repair would definitely rip my pockets
