These tires seem to be both low budget and very popular.
Sumitomo is part of the Goodyear-Dunlop family somehow as i understand it.
One observation that is striking to me is the SIMILARITY between the Sumitomo Srixon and Dunlop Sport SPA2!!
The HTR+ looks like a ultra high performance but budget (vs. Michelin Sports, GY F1's etc) tire.
