a strange wear pattern has emerged on my rear 205 (2000 M2) . . . . .. there's a small slice (or what appears to be a slice) from the outside edge of the treat to about 75% of the way to the center of the tread area, on both sides of the tire . .. . . less than 3000 miles on the tire, all other wear looks normal . . . .. any ideas? | ||

Bomber, is that all the way around the circumfrence of the tire on both sides or a spot of unusual wear? Can you post a photo? | ||
| Road_Thing |
Could it be damage from road junk? Or maybe a belt trying to come loose from the carcass? Just a couple of WAG's... r-t | ||

I had the exact same thing on my 2000 M2 (a D205 or D207, mine was the touring one not the sport one, I can never remember which number is the touring one and now I run D220's so it no longer matters). Anyway, I was initially blaming the tire, but in hindsight I suspect I hit a sharp edged road hazzard. Around here when they button up street repairs for a time, they put down 1 inch thick plates of steel, I suspect one of those. I also recall hitting a raised curbish looking thing when I went over a railroad track at some point. On mine I could see no cords were cut, and I ran the tire for a long while (including a trip to Deals Gap and the Cherohola). I replaced it a little earlier then I would otherwise, but not until it was REALLY worn. No problems. On mine, the cut was on both sides of the center, with about an inch along the center not cut. It was almost a "smile", curving up at the edges (actually I don't remember if it was a smile or a frown, but you get the idea). When I asked the same question, Blake mentioned that he had the exact same thing when he nailed a curb. Bill | ||

gents . . . photo tomorrow (I hope) . . . . it looks like someone took an exacto knife, started at the sidewall, and went towards the middle for 2 inches or so . . . . . and then stopped . . . .on both sides . . . .. there was a discuission about this very topic a few months aog, but I couldn't find it (my lack, not the search engine's) | ||

I had the same exact thing happen to a D205 rear. I assumed it was the result of slamming into the far edge of a sharp edged hole cut into the pavement, but I've since heard of other instances and one in particular where the dealership recognized that the tire was indeed defective. I ran mine through two track days before it was completely worn out never had a problem. Knowing then what I know now, I would have asked for a replacement. | ||
| Bomber |
All thanks . . .. . I swore I could remember a thread about this (and a pic or two?) . . . .. I'll try to post a pic, and will also check with the dealer . . . .. it ain't causing any trouble, but I'd just as soon not wait for trouble to find me (does that mean I should try to hunt it down?) | ||

When I got rearended my rear tire was horizontally "sliced" across the tread, sounds like what you describe. Could be a manufacturing seam gave way, or a sharp edge or pothole or steel ditch cover got you. How's the tire pressure? | ||
| Bomber |
Tire pressure held to with 1.5 pounds (all winter!) . . . . . . . the slice is only about 1/32 inches deep . . . . rubber only (obviously) . . . . I would have thought that striking a shrp object woulda sliced the middle of the tire first, rather than the sides . . . . . . | ||
| Road_Thing |
Yeah, you'd think so, but the sides get put in a bind first, against the raised edges of the rim, before the center of the tread hits anything hard. Are there any marks on the sidewalls? | ||
| Reepicheep |
Also remember that is a dual compound tire, with the center (the uncut part) being harder tougher rubber and the edges (cut part) being soft stuff. I've got that tire as part of the kids playset, I will look and see if I buried that scar or if it is face up, and post a picture if it is visible. Sorry, I am not dedicated enough to dig it up for you unless you get REALLY desperate! (addendum... I went and looked, sorry, scar is buried... I can dig it up if you need ammo for dealer / dunlop, but I don't know what it would proove). | ||
| Bomber |
Reep . . .don't go diggin on my part, but thanks for the offer . . . . . . . thang .. .. . you're right about getting mashed against the rim, and, nossir, no marks on the sidewall | ||
| Road_Thing |
OK, here's my best guess: Aliens landed in your garage and cut the edges of your tire while they kept you in suspended animation! r-t | ||
| Hoser |
Almost every D205 I have ever used has done that , which would be about seven pairs , Good luck trying to get warranty. D220's in use since being released , I like em . | ||
| Bomber |
thang . . . .. .excellent! do you think they might have installed Nallin heads while they were at it? | ||
| Road_Thing |
Alien head job? Naahhh.... | ||

reminds me of an evening I spent in An Hao . . . | ||

We saw a lot of those slices on NEW tires at one time in the past: "Parts Pro's" were using a box cutting knife to remove the wrappings that the tires came in. Slices didn't really show until the tires were filled with air, and sometimes not until somewhat later. CAREFULLY inspect rear tires when they've been mounted and before you leave the dealer/shop. | ||

Can anyone tell me how does the 205's compare to 207's on everyday cury adventures? any help would be appreciated. | ||
| Blake |
The 205's allowed me to scrape pegs. The 207's provide even better grip but not so good durability. It is a trade off. For evey day riding, and if durability is important to you, the 205's are the way to go. The 205's however have been superceded by the D220 series that are supposedly improved. You might consider a set of those. | ||
| Dynarider |
Blake is dead on with that. Had the 207's & they lasted maybe 4000 miles. Swapped to 205's & couldnt really tell any difference in grip..well they would slide a little bit when cold but once warmed up they stuck fine. 7000 miles outta a 205. | ||
| Blake |
I am SOOOOO jealous of you guys that get such great mileage out of your tires. I NEVER get more than 5,500 miles out of a rear tire, even on long trips where I am riding very conservatively. | ||
| Mikej |
Take the huge green couch out of your saddlebags and your mileage will go way up.  (Just playing and seeing if the old commands still work.) | ||
| Road_thing |
Yeah, and isn't Blake the guy that travels with THREE Crescent wrenches in his tool bag? I mean, I can understand having an SAE Crescent and a Metric Crescent, but what's the third one? Whitworth?? r-t ...just raggin' on ya, Blake--seriously, thanks again for the time and effort on this board! Cold malted beverages are on me when we meet! | ||
| Blake |
Four! Two biguns and two littluns. | ||
| Road_thing |
Oh, tent pegs, now I see!  r-t | ||
| Knickers |
I concur w/Blake. I'm down to the wear bars on my rear D205 at 5600 miles. If 207's are giving 40% less milage I'll prolly stick with 220's. Kurt | ||

A friend of mine is just starting up a new bike shop mainly for parts and he told me he had some dunlop 204's in stock are 204's and 205's the same tire? | ||
