I got my ’06 Uly inspected yesterday and the rear tire thread depth was 2/32” – the minimum to pass inspection. Normally I’d go a bit beyond this but I’m leaving on an overnight trip tomorrow, approx. 800 miles (no slab and no rain) over the next few days and I’m concerned about how quickly it might get to the belts.

Took 3K even to get this far: 2/32” thread, center inch of tire flat spotted. It’s my first D616 and it’s worn more quickly than I expected.

Threw a new Diablo outside this morning before leaving for work so that the sun can warm it up and it will be easier to spoon on if I need to do it – will change if there’s no feedback or if the feedback is that I’m less than 1000 miles or 25% of tire life away from the belts.
Any data - miles, percentage of total miles etc - on how quickly the D616 wears at the end of its life?

Wow, you go thru 'em quick. I get 5k out of my rear 616's...but I tend to swap them out when I get to the flatspot, haven't run one to cords yet.

What sort of 800 miles are you talking? Superslab, right down the middle of the tire? Or back roads? Heavy load (passenger, full bags, etc) or solo? When I did Buelltoberfest last year I was nearing the end of my rear's life...rode from Maryland to TN, met up with Etennuly and a bunch of others, rode to TWO (the long way), rode around for a couple days, rode home, and was about 1k overdue for my service and my tire at that point. I debated changing the tire before I left...and when I got back I had a lot more left than I expected. That one - Dragon included - netted me close to 6k miles. I probably could have gone a little longer....but didn't want to push it.

Comes down to personal choice.

Worst case, where are you going? Is there a shop nearby that can sell you a tire in a pinch if you have to have one?

800 miles of twisties in the mountains of Virginia and West Virginia. Loaded? no, me and a backpack on the seat - probably 200 lbs max.

No time for shopping on the road - it's a two-day ride and there's no time for hanging around a shop.

What's your safety worth?

Since I got 7K+ on my first 616's, and 6K+ on subsequent Syncs, I think I could do 800 miles easily on that tire.

But you're wearing it out faster than I did so I wouldn't gamble on it personally. Are you running stock pressures? What's the manufacturing date on that tire?

on my 1998 M2 Cyclone with the stock Dunlop tires. I think it was a D607, I ran it to 15,000 miles before I saw the white cord down the center of the tire. I switch my D616 at every 10,000 service. I could get more mileage out of them but why chance it.

I get about 10k out of the rear D616, nearly 15k on the front (lots of commuting)- that's when the funky wear pattern begins to drive me nuts...

when the rear tire on my M2 Cyclone had just over 15,000 miles on it I knew that I needed to replace it and was riding on my way to the dealer when stopped at a light, a car pulled up on my right side and said that my rear tire looked funny. So I pulled over to the shoulder and discovered I could see the white cord running down the center of the tire. I then proceeded slowly to the dealer and had them change it. That could have been really bad had I been zipping along and the rear tire blew out.

Thanks to all for the comments and data - there sure is a huge variation in tire life out there.

I took a good look at the tire after I came home and my comfortable guesstimate is that it's good for the trip. I've been running it at 38 psi and I'll up it to 42 to reduce flexing, heat build up, and wear. I'll update the thread when I get back.

I'd replace. If you're down that low, there's not as much rubber to squirm into road imperfections.
If you know you have to buy something now or later, might as well get it now and enjoy it 'til later.

May have oversold how worn they are in my first post. The pictures:





It's my first time with D616's but I'll be very surprised if I hit the cords in two days.

It's beyond my understanding why some riders are OK with riding down to the cords on a bike, or a car for that matter.

By the time the rubber wears down below the grooves it's extremely thin, hence the wear bars. Puncture magnet.

But, to each his own.

When in doubt, change it out...unless of course wanton endangerment is what your about, then minimal tread is perfect for a long route....

So your trip will be 400 miles out and 400 back. I would use that tire. But then I don't look at a 400 mile ride as much of a long trip.

Consider though, I am frugal about mine, I never run them through to the threads, but I squeeze out most of the miles that are in a tire carcass.

Replace it before you leave. One sharp rock could ruin your whole day. Or cost Alex Prior his second beer of the evening just when he starts to get settled in...

Is there a rule somewhere that only the thin parts of a tread can be hit by a sharp rock?

Last month I was doing about 55 to 60 mph in a slight turn when the rear jumped about a foot up in the air and six inches out to the right. It was flat before it landed. Not a issue for feeling at a loss of control. It just settled back in and rode like it was a bit loose, like it had a flat tire.

I rode it a total of about three miles with it flat to get to a gas station where I was comfortable waiting for my rescue. I did not want to hold up the other riders from their evening plans, so they were able to leave me there without concern. At 30 MPH, although squirrelly, I believe this Michelin carcass could have done at least ten miles before worrying about it coming apart.

I was about a hundred miles from home, where I waited for my son to come get me with my truck.

This was a Michelin Pilot Road II, I planned on another 2,000 miles out of it. These tires for me, have been doing nearly double the miles of the Syncs and D616's which I did 6,000 miles on average with.

The only thing about this tire event that would have pissed me off, would have been if I had put my new tire before this happened or if it were at the beginning of my day. It was a beautiful day of riding.

I'm here to steal a little of Jesse's thunder. While riding through the mountains of WVA and VA he, well, found out just how far the tire would go. No harm that I know of has come to him, just his wallet.

I got a call from him about 7PM Friday asking if there was a shop near him in Lexington, VA that could get a tire on his bike for the trip home. Long story shortened, (I'll leave you some thunder Jesse) he has a new tire, thanks to the GREAT folks at Wayne Cycle in Waynesboro, VA,(I didn't have an extra for him) and was back on the road by 11AM this morning.

That's the BRAN network at work!
BRAN, It's full of what you need to get YOU moving.
(yes Blake you can use that if you like)

Yes, my guesstimate was wrong...four hundred and sixty miles later and the tire was shot, the center half inch had started to shred and the cord was beginning to peek through. Wear up to lunchtime on Friday was barely noticeable but the 80 degree weather in the afternoon and the couple of passes up and down the mountains on 33 and 250 in Virginia did a number on the tire.



First order of business after checking in at the Days Inn in Lexington was to source a tire. The manager of the adjoining Pancake House heard us asking about bike dealers at the check in and told us about Wayne Cycles in Waynesboro where he had bought his Star cruiser and wrote us up directions on how to get there.

Netbook and Xbduck to the rescue. Got the answering machine at Wayne's...but BRAN is always open.

I was leery about putting all my eggs in the Wayne's basket, particularly on a holiday weekend. Scanning through the entries for Virginia I noticed one number with the same exchange code as Wayne's and decided to give it a shot. And what a stroke of luck that turned out to be.

Earlier in the afternoon, my riding buddy Garry and I were taking a break in Churchville and had a few words with the driver of a truck that pulled up briefly, the driver rode an XB9SL and gave us a thumbs up on the Uly. Turns out we were talking to Xbduck. When he answered the phone, Howard immediately recognized my voice, offered us a place to stay and said he'd contact a friend who worked at Wayne's to make sure they'd be able to take care of us in the morning. A couple of phone calls later we find out he's spoken to the owner and we arrange to meet there at 8:30 in the morning, they'll put on the tire if we bring in the wheel, woohoo!

Howard is there before us with tools,ratcheting straps,bungees,locktite and is on first name terms with everyone there. Garry scopes out the landscape and sees a new use for the handicap ramp in the front of the store - the first time it's being used this way according to Wayne's founder who's on his feet working while Garry and Howard relax.



Howard secures the bike



New Rubber



A big shoutout for Wayne's, for BRAN and Xbduck, and sincere thanks to your wife and family for taking you from them on the holiday weekend.

No where in your posts did you say you were going to rip the shit out of it on some twisties! It looks like it has been on a track day adventure. You had too much fun for that tire.

When someone is going on a trip with a tire that is in the condition of the one you had, one would presume you would take that into consideration as to how you are going to ride it, you know.....like being conservative.

The way you are riding it you should be stocking spare tires at home, mounted up a new one, and should have taken an extra one with you!

That definitely wouldn't work - my wife would start asking serious questions about what I was up to
