Our Acme dolly is older so it isn't galvanized; its powder coated black. I have found that the dolly tires leak a little: have to top them off before every trip--including the spare I picked up.
As far as getting it as far forward as possible I've found that the car & dolly have to be almost perfectly aligned when loading. If not one side or the other will be away from the front guide. I'm usually pretty bad at it after winter since I haven't loaded up the car in a while--I'm sure spring 2021 I'll be horrible at it ! LOL
On two of the cars we've put on the dolly I found that I compressed the front tires after driving a while and tightening it up at the odd rest stop. (Once at a gas station we had to turn so tight that one of the front tires popped out of the straps and we had to basically unload/reload the car to get them straight again.) I've never caused a flat due to it and the tires returned to normal after unloading.
The Bolt also has pretty low ground clearance causing the bottom to barely scrape at the front rail of the dolly. So far it hasn't caused any damage, however.
Here is the collection of vehicles we've put on the dolly, LOL
