....are just starting to show on rear stock Dunlop. I am scheduled to leave on a 1000 mile round trip Thursday. Not sure my indy can get to it Tuesday/Wednesday and he is closed Monday. If he can't, I'm thinking the tire has another 1K in it but I'm usually not a risk taker with safety stuff. What y'all think? Pictures in post below...

 

It seems the lower they get the faster they wear but im sure it will be ok

 

I'd say no. But that's me. I don't trust a tire on the wear indicators. If you find yourself riding in a torrential rain, how would you feel? I wouldn't be able to get my mind off that tire that I knew was worn out.

 

When they hit the wear bars,they are worn out. Won't even pass State Inspection at that point. My experience has been when they get around that point it seems like they wear down even faster.
Even though we are in Texas,it might rain too.

I'd replace before your trip.

 

The one thing you can be sure of is that your tyre is about to wear out and won't last the trip! Ain't worth starting out on it IMHO. In my experience if you hit rain - well don't!

 

thanks for the words of caution. here are some pictures;

 

Just another opinion for what it's worth... Those tires look good for at least another few thousand. And as for wearing faster near the end of the tire life - that is simply not true. The wear rate actually slows as the tire wears because the contact patch gets bigger. If you don't believe that, measure your tire when new. I'll bet the farm that the first .100 of wear will occur in fewer miles than the next .100 assuming similar riding conditions.

I'd take your 1,000 mile trip without a second thought. The only caveat is that wet traction can be compromised with the shallower tread depth if there is enough water on the road.

I would take the trip with that tire tread.

 

Get a tread depth gage. Cheap and you'll know for sure. From the pictures I would say you have 2-3/32nds left. The wear bar is 1/32nd which is the replacement depth according to the service manual. I wouldn't be too concerned with that much tread since it has about 2-4K useful life if my tread depth guess is correct.
