For a stock rear tire 240/40R/18

How can you tell when the tire is worn out? Other than being no tread on the tire. These wide rear tires can be deceiving. what is the new tread depth?

Thanks...

There should be a "wear bar" in the grooves of the tread. When it gets to the wear bar, it's done. I don't like to ride on a low tread tire, so right before it gets to be slick, I swap mine out.

On my stock rear my telltale sign was strings hanging out. It appeared ok one day. Then the the next it was cording. So you should have your next tire on standby because they go quick.

When you can see the belts - well you waited way too long. "Wear bars" on the tire will tell you when to change it or if you have uneven or improper wear.

When you get to the wearbar your tire is paper thin and a sharp stone can punch a hole in it. I don't wait for the wear bar to appears, when 2/32nds show up on the tread depth guage that tire is history. My brother in law tried to run one down farther and it blew on him. Could have been caused by anything, a stone, or piece of debris in the road is all it takes when they are that thin. I like running thru the gears, settling that need for speed every now and then and I am not doing it on a paper thin tire. You can do whatever you like and its definitely up to the comfort zone of the person riding the nine. But with all that power safe is better than sorry. Enough said.

No tread - Past Worn out. When you get a new one put on, Take a knife and cut the old one right down the middle like a bagel. See how thin it is and remember that when the new one gets worn down. The tread depth on a new tire is really not that deep. I have a new Metz unmounted that measures 7/32 in the middle of the tread. Other tires will differ but if I replace at 2/32 that only gives me 5/32 of riding tread. Not much.

:agree: watch your wear strip, go past that and this could be you :redfaced:

yep to all above

[My1st109]

Don't see the wear bars yet. So must be okay. Just looks a bit thin if caught in the rain.

Thanks for all the replies. :bigthumbsup:

The new tread depth does not really matter, only the tread left. I have took of a tire that had a couple of thousand more miles left on it to go to the meet. So I guess it all depends on the future road conditions. MD state minimum is 2/32 of an inch to pass inspection.

[My1st109]

I was thinking that if the tread depth was xxxx then I could tell by what I had left, xxxx.

Thanks

The wear bars are visible even when tire is new, its a raised rubber bump inside the tread groves so when the rest of tire wears to that point the long grove will look like its two shorter groves

You can measure from good tread to wear indicators and tell exactly how much you have before she is toast

Tons of info on tires here, the stock tires are junk. Low traction, fast wearing and expen$ive

Most love the E3 250 or Metz 260 for stock rims

Thanks Jimmy. I ordered an E-3. I have had those on other bikes and they wore really well. Of course the correct air pressure helps a lot too!

Thanks!
