I guess I have the 650Brah HR2 EXO in 60a compound, but Maxxis (and seemingly hardly anyone else these days….) don't really want people to know exactly what the composition of their tires is. From this table I can confirm that my tires are black and have an ETRTO of 61-584. The tires also have threads and they are floppy…. As for compound, genuine width (my 2.4 is massive compared to a 29er 2.3 that I had), weight….who knows! Max PSI….yeah 60PSI FTW :cow: Durometer reading? Who knows! 'Single' compound? WTF is that?!
Anyway, ignoring companies' complete lack of ability to supply simple facts, I'd describe the tires as 'reasonably good'. Despite not having 'TR' written on them, they aired up fine on my RF Turbine rims with just black tape covering the holes, the supplied plastic tape and some random valves that I found. Ideally I'd like a 50 durometer tyre up front (I don't really need anything super…umm….tacky) just to give a bit more confidence on the steeps in the wet.
So to summarize, I don't really know what tires I have, but they are big, black and round, and work OK. I hope that helps ;)
