2000 xr650r love this pig with monster meat teraflex tire

if any body wants to know my pig loves its new shoes,,,,, rode it today with the 150 teraflex tires on it and love it. only had to take the shock gaurd fender out. it hooks up and powers thru awesom know i just need to dial the suspension in cause this poor pig is ridden by 250+ boy. more riding like today and ill lose wait do to the terror of being lauched into outer space powerfully lmao

We've been using them since the 80's, but recently my buddy was told they don't make them anymore. is that true? was yours purchased from someones existing stock? is there any indication that they are still available?
a terribleteraflex is a hard thing to beat, and a hard addiction to let go of. it's the only steel belted dirtbike tire I ever heard of.
I would love to know where to get them if possible.
thanks.

Does it fit with plenty of clearance? I have a 140 series D908RR and it barely clears.
