Thanks for the responses. It is the front n a mt21. It's hard to see in the pic n I'm not very good with a camera. I'm trying to figure out how to explain this better...
That tire has kind of a 2 1 2 center knob pattern kinda like =-= if they were centered on each other. There are other knobs these are just the main center ones. The angled knobs in the pic would be the =. At the high side of these in the center they measure 7/32. The - knob measures 9/32 at the low side.... This is only the second front tire I've ran down. The first was the deathwing... The deathwing had an angled wear also but all the knobs had it evenly... It seems weird to me that one set of lugs is wore down more than the other.. If I look down the front of the tire instead of seeing all the tops of the knobs I only see the top of the - knobs... I didn't measure n compare low side to low side but I'd guess the difference is .25" or more... It almost seems to me like the knobs would have to be made out of different compounds to make it wear this way... Not that I always brake when the bike is straight up but if I have to brake hard I try to keep her as straight up as possible...
Dunno if that will make sense to anyone... Tried to explain it without assuming you know the mt21 tread pattern... Does this still seem normal to you? I think I thought about it too much tho....
