"Matrix" was Trek's house brand rims and were OEM on most Trek bicycles before they started to used the Bontrager name. Having owned a couple and worked on several more Treks with Matrix rims I never found them particularly difficult to install and remove tires. Some tires were a struggle and others fit fairly easily but that's true of all the other make rims I've dealt with.
