The rear IRC GP-110 was bald at 6,000 miles. I should've replaced it back at 5,000.
They're good tires. $130 a set for the G/S which isn't cheap but at least it's on the cheap end. They look cool. Mileage is about average for a 50/50 dual sport tire but they're listed as 90/10s. They handled better offroad than the Distanzias so I think the 90/10 rating is off.
Conspiracy Theory of the Week: they might've put the 90/10 rating on the tires because more folks buy 90/10s than 50/50s
I mounted a rear Distanzia today.....backwards. Okay, I screwed up but I thought it'd be an opportunity to see if the whole 'backwards tire' thing really changes performance much. I'll cautiously take it on the road this afternoon. If it's okay I'll try it in the woods.
