I haven't had any customers complain about the pneumatic wheels, high quality.
I think the biggest concern for me with solid wheels would be the weight.
The lighter the better when it comes to tools in the crawl space. I'm using aluminum, not steel.
Also for me to ship one crawler from California to New York costs about $100 by UPS and that's the most affordable.
The highest quality and the least weight is the goal. If anyone had a wheel/tire issue I would take care of them anyhow.
Truthfully I have not experienced that issue.
