Hello Alexander,
The tyre Freightmaster CX is manufactured in china for Watts Industrial Tyres as part of a J/V with another company. We have been buying & sold these tyres for a long time now and have had no complaints about them other than they are a bit narrow in profile. I believe they are changing profile to suit European market demand.
Years ago Watts made a 2 part solid tyre called the "Freightmaster" and to my knowledge they did not perform too good. The new Freightmaster CX is a better construction & quality tyre.
