**** that! Do you see the profile on that thing? It looks like a horseshoe! I'll definitely be going with a 160 on the Kat.

lol

Got a closer pic of the top of the tire looking from the rear so we can see the profile?

Profile is the same as the 160
both are designed for a 4.5" rim, Ive run both the 160 and 170 Conti's no noticable handling difference.

currently running a 170 conti motion
ill get a pic of that later

170/60 is a taller and wider tire. It can't have the same profile as a 160/60, it's just not possible.

really ?
you do know that the 170 has a more "cut in" shallow side wall upto the bead right !
it is VERY POSSIBLE
There is a reason why these tires or any wide range of tires from some mfgs ie. 140-170 are designed for given sizes of wheels ...to maintain thier shape/profile. Dimentions are slightly different but shape is the same. Its not flexed, buldging and distoreded on the wheel.
if you tried to put this tire on a smaller wheel it would distort the profile. But because its designed for the wider wheel it maintains its proper profile.
If the profile was changed because of being distoreded it would not be 170mm wide it maintains its proper profile as a 160 would on the same rim. Both tires maintained thier profiles and have the same shape without distortion

If you would like, I will point out the obvious profile distortion on that 170 that is much more dramatic than on a 160 when i get home and have a moment to blow up and illustrate it clearly. Your pic does show it really clear to me though...

Hint, the last 1" of the right side bottom... you can see a drastic change in the radial curve.

Please do. I'd like to see as I'm looking at new tires.

normally I don't get involved in this. however I recently bought a set of Motions. the 160 was backordered so I got the 170/60. it was made to fit my 4.5" wheel.[according to tire info] I didn't get very good mileage, replacing it after only 2500 miles. the replacing 160/60 tire I got about 6K. never got to the edge on either. I now run a 150/70. I get to the edge plus it feels better on turn in. I did not like the PR3s I had in between. had no fitment issue with any.

So what tire do you like?

it looks like that because its looking directly down/ following the tread slot the last one inch is not distorted.
Also if you notice there is no chicken strip, there is but its about 1/8"
no matter if its a 150 or 160 or 170, I wear all my tires to the edge.

if a tire is distorted its not at the edge that you see it. its in the middle.
a 170 thats pulled in would measure somewhere between 155-165 Not its actual 170 width.
also if it was distorted I would not be riding to the edge on a ****ty conti motion in the winter in canada.
IveI measured every tire from 150 to 180 on my rim. Conti and Bridgestone are the only tires that are oversized that do not distort up to 170. A 180 measures less then a 170 on a post rim

Well I'm not going to get into an argument over the webs about a pic you took that you now say is "misleading" (but... it was posted originally to prove your point wasn't it?... ... I look at all 4 corners of that profile and see the same thing... it drastically changes the radius of the profile on the last 1/2-1" of the tire, and it does much more so than a 160 on that rim.

I'll just say that I don't agree with your statement that 2 differnt sized tires would have the same profile on the same rim size and move on.

That 170 looks like **** HD...sorry...nice and pinched.

[hardlydangerous]

I said I would get a pic LATER

the second pictures are a 160 Conti motion I took last fall. I posted so you could see the profile is the same as the 170 .
it looks that way because its 60% worn flat down the middle.

Once I can wash my bike ill get a pic of the 170. But right now its freezing and snow on the ground.

FWIW Im on my 3rd tire this season 16k

You guys need to learn a lot about different tire profiles, the different shapes for different riding styles and track conditions.
There is very good reason why some are more flat area while other are more peaked.
Also MFG's dont recommend tire sizes for two small of wheels. Plain and simple.
Just because a tire LOOKS one way to you guys means nothing.... different model tires are designed that way
