thanks for the positive reports re canadasmoto , kenf
to be clear , they weren't ignoring me , they somehow copied wrong contact info , so they couldn't reach me despite trying . i probably will give them a chance to make me a satisfied customer however i am one of those guys who likes to actually see what i am going to buy , and having a guy sell from experience is reassuring .
that said , i'm sure any new tires would be better than the worn out TW's , but i'm pretty glad i wound up with the tires i did get .
as for the mounting , all i gotta say that was a helluva lot easier than i thought it was going to be .... not saying i didn't get a little warm , but i've seen guys have more trouble with DH tires on bikes .
heres what i did for the install ... i put a bit of air in the tube and then put it into the tire . i laid the tire on the ground , and then placed the rim on top , inserting the valve into the hole . i stepped on the rim at that point , forcing it into the bead of the tire . then i basically walked around the rim working it into the bead , eventually the opposite side popped in .... no tools . i stepped on the rim to push it right down to the bead on the bottom side of the tire . then i levered the bead of the upside edge onto the rim , last lip at 90* to the valve .
disclaimer : this was a second install , after i had mounted it backwards the first time . the upside was that the entire bead in and out as well as the rim was well lubed .
in addition , the long , curved iron was essential ... don't know if i'd leave home without it .
TW , i had them in the shop with the heat cranked all night ...
