The upcoming Cadillac Escalade IQ is going to have an optional 24" wheel fitment. With the 50mm sidewall, this makes the total outside diameter of the tire 35". That's the same tire diameter as you'd put on a rock crawling Jeep Wrangler to take to Moab, but it's instead on a (estimated) 8500lb (3855kg) full-size luxury crossover marketed as an "executive" vehicle.

For comparison, the Hummer H1's tire outer diameter was 37". We're quite nearly to that level of insanity.

I'd reckon just a tire is going to weigh nearly 50lbs (22.6kg), with the wheel about the same. I can't imagine how "fun" changing a 100lb wheel+tire is going to be when rotating tires. Moreover, the reality is the cost of the those tires will be comparable to near R-compound top-end performance car tires. Never having personally considered tires/wheels that weighed anywhere near this, I wonder what the point was when shops had to get entirely new wheel balancing machines, etc. to adequately accommodate these ever larger sizes and weights.

The battery impact for an EV is also going to be substantial, as is the impact to braking performance. It's really just maddening.
