This is why you don't run low profile tires

Except the extra set of 20" factory Dodge wheels I have that I didn't use have "made in China" proudly cast into them. I would bet if the GM ones don't say "made in China" it's only because they actually were but told them not to print it on the wheel itself.

In defense of the low profile tires, my Aspen handles much better with the 20's compared to the 17's but it's only really noticeable if I was autocrossing the thing. Then again I was the only guy with a pickup at the autocross events I entered LOL!

If I was running a 20-24" rim, you can bet that I would have it wrapped in a 35-40" tire. No rubber bands here, no sir.

(37x13.50 on 22x14s)

Yes sir!

That's not low profile, that's just gigantic.

I would not put it past GM to lie through omission on something like that.

Yes, putting taller wheels helps up to a point.
The over all #1 thing you can do to a 3rd generation Camaro like mine or firebird or T/A to increase the lateral skid pad G forces the car will hold is to put 17 inch wheels on it. But you still continue to run a 26 to 27 inch over all diameter tire (not exactly rubber bands).
You can go larger than 17 but it become hit or miss with that platform for some reason.

It affects 'turn in', the time it takes for the vehicle to respond to steering wheel input.

Supply vs demand prolly. Maybe just a more common size rim so a larger market.

I can show you a similar thing (large crack in the side bead) with a regular profile tire, from hitting a rock that rolled down the mountainside.

Super low profile tires are the stupidest thing ever. Is there a handling benefit? maybe a very small one, at the expense of a harsher ride. I just can't see going any lower than a 50. And people that go lower than that on a truck should be beaten. It looks like ****.

Maybe. There are a lot of variables in play there, even just in the wheel/tire realm.

It's merely the only thing I could think of in favor.

The best turn-in I've had was on 145/15s on 5.5" rims. But they couldn't keep up with the brakes (downhill in the mountains), so I went to 165-50/15.
