190 Tire
Has anyone replaced the 200 series tire for a 190 and what kind of results did you get. One more question, does everyone get thier tires from tireexpress.com???? Let me know, any feedback would help.

A bunch of guys have been doing this for a while and I finally got around to it my last tire change.
Since I live in the Deals Gap area and ride the twisties (slowly) I can say that it DID make a difference in handling for the better in my case.
I would recommend trying it, if ya don't like it you can change back soon enough.

190 tire
I'm on my 2nd rear 190 tire. I remember the only difference I could tell was in the tight twisties. Long sweepers really didn't seem that different. I would like to try a 190/55 or even a 180 on the next rear.

Knee dragger. Prefer the 200. Don't like the 190. jonwright & I debate over this subject. But no way would I ever recommend a 180 on a six inch rim.

K, we can definately agree that 180 isn't good for haulin' arse. I'm glad I went back to a 190.
Now, I did go from 200 to 180, then up to 190. So, I'm not sure if I'm losing tire contact patch at high lean angles (as K contends - and I don't necessarily disagree).

I could tell a big difference when I switched to a 190. I have had both dunlop 208s and bridgestone 012ss. I prefer the bridgestones and they seem to work pretty well. I did a track day and 2 trips to the gap and they lasted about 2500 miles.

i just went to a 190 after running 3 different 200's. I am very happy with the handling with the 190...the only ill effect I have seen is a slight head shake at very high speeds....like 170 and higher......but how often do you go over 170? i usually get 3500 miles or so out of a back tire, depending on how much time I am spending in the mountains....

Why is that?? Suzuki issured the Gixxer 750s with a 6" rim/180 rear tire. THe 180 I have on my bike works fine.. though Im going back to a 190.

I think that the rear rim on the 12R is 6.5"? No?

I believe it's a 6". At least on the A series.
Dunlop's tire guide and many others have always said that the preferred rim width for a 180/55 is 5.5". It should be noted that they also find the 6" rim to be acceptable, just not preferred. It the opposite with the 190/50, with the 6" being preferred.
A quote from Dunlop's website:
Correct rim width may be crucial to handling and stability. A tire that is installed on a rim wider than recommended will have a flattened profile, and a rider may easily reach the edge of the tread during cornering. A narrow rim will alter the tire profile, concentrating tire wear in a very small area during cornering, with a smaller contact patch during braking. Remember: Tire clearances are important.
Still, this statement really does not answer the question concerning a 180 on a 6" rim. Even though the "recommended" size is 5.5", they still acknowledge that a 6" is acceptable. Luckily, in my case, I do not have the riding skills to exceed the tread's edge during cornering. I will all be a moot point for me anyway. I'll be buying 190's for a different bike after the first of the year.

Metlzer Sportec seems to be the "cant go wrong" brand . Get a 190/55 120/55 setup. You can always go back to the 200mm rear if you really feel like you need to.

180........
I've ran 3-180 Series rear tires on my bike. 2 M1 Sportecs, and 1 Pirelli Supercorsa. They work fine for me and they hold the road great. Just this past week at the Gap I rode several miles 2-up with the 180 Sportec rear. I'm not talkin' about pussy footin' around either. 2-up riding at a toe slider draggin' pace, anyone of the guys who were there can attest to it, and the 180 worked perfectly.
I am looking at two brochures, one is a Pirelli Supercorsa, the other a Metzeler Rennsport. In the "Rims Permitted" column they both state - 5.50" - 6.00" for both the 180 & 190 series tires. I don't doubt that the 180 will be a little flatter, but after looking at 190s on some of the guys bikes at DG6 I can't see much difference in the profile. I'd like to see some hard numbers on how much, if any, the contact patch will vary between a 180 and 190. I'm sure there are several factors to be considered. Rider weight, what air pressure will be ran, etc.
To each his own when it comes to tire choices. I say run what you feel comfortable on. I like the 180, and the 12R seems to like them too. I've pushed the bike pretty good on the past 2 gap trips with 180 tires and it did fine, even with the added weight of a passenger. I do have a new 190/55 Supercorsa mounted on my other rear wheel that I will eventually run, but I suspect I'll stay with the 180. They are cheaper and the do the job for me, the 200 makes my bike feel like a barge. I will never willingly run a 200 ever again.
Here's a 180 equipped 12R hustling 2-up @ The Gap -
Like I said, run what you feel comfortable with. I just wanted to say that you CAN run a 180 on a 6" wheel and have good results.

I am running a 190/50 and a 120/70 M-1 Sportec, seems to be the best combination I have run on my bike....Dunlop 208's were a very close second, only because of cost did the 208 not my favorite......the Pilot Sport HPX is a good tire but I was running a 200 on the back with those......

To me the 190/50 aint shit.
I screwed up bad. I put Pilots H2's Race on for Deals Gap trip. And I had a sweet set of 190/55's Dragons which I thought I'd save and also the same tire I removed for trip. Kicking myself baddly removing my dragons. I thought what the hell. Can't be that big a difference. I WAS WRONG.
I had to raise the rear to get the bike to stop wallowing like a whale and then I had a real bad rebound problem which I cured with removing rebound and adding compression. About the time the bike felt comfortable it went in the trailer to come home. But it never did come around to the way it was before the tire change.
My frist impression is 190/50's suck like the 200. I'm keeping notes on my tweaking so I can return settings when I put my 190/55 back on.
I'm a rookie at changing settings and height for tires but If I don't do it whos gonna?
Just remember any slight change in tire, height, and settings start a domino effect. So keep notes.
Don't get me wrong for some the difference would mean nonthing. if riding city and stright roads. But in the twisties the difference is huge.

It's really interesting to see everyone's different passion come out when it comes to debating tires. And as I've said before, the most important aspect is your individual comfort level with whatever tire you choose. So many things have to be considered, and those things have been pointed out here by others.
So much depends on your riding level. Leaning over and going around a corner smoothly is one thing. Grabbing a handful of throttle and attacking the corner and powering out is another, and a completely different set of perimeters to judge a tire by. That's how I evaluate them. So that may not be applicable to you and that's cool. My comments are completely biased towards dedicated hard mountain riding and track days. No two up, no cruising, no moderate pace when it comes to corning. I'd love to ride with some other 12 owners (if you're in SoCal) and then more realistic notes can be compared. Unfortunately, I don't get to ride with any guys with 12's, only full-on "Sportbike" wiennes. I've got to really hustle to keep the 12 on par. So make sure you read everyone's opinions while trying to make you own assesment.
I'm not recommending this for everyone, because exploring the limits of cornering attitude and laying the lead to it into/out of said corner on the 12 in particular, will get you in trouble very quickly. Enjoy and keep it on at least one wheel.

I am someone who usually doesn't notice much. The 190 handled much better, but I went through the tire much faster
Now this is subjective. The 200 felt much more cushy sp? or smoother!

There is also one consideration when comparing tires. It is that usually - at least us mortals who have only on set of wheels and limitid money - buy new tires when the old are worn out. So whenever You put a new tire it is going to be better than the worn out. I very well remember when I changed my first set of Pilot Sports to the second ones. I almost dropped the bike in the firs turn - leaving my home yard!!! They turned that much easier! And usually all the tires are nowadays good - some maybe better in one thing and the others in other things but to everyone what they like. And also about the 200. When I'm measured the actual width of my Pilot Sports in 200 they're actually 'only' 190! Where as the Avons(but don't ever buy them) where really 200. And if I remember right so were the Bt010:s also. So that maybe the reason I really like the Pilots allthoug they're kind of expensive... :-(
