bushman57 Posted May 14, 2019 Share Posted May 14, 2019 I have some excellent rear tires left over that are 190/55 ZR17. Has anyone ran one on their 2019 Tracer? Thanks Link to comment Share on other sites More sharing options...
jsp Posted May 15, 2019 Share Posted May 15, 2019 Don't put a 190/55ZR17 on a 5.50 inch wide rim. You won't like it. john Link to comment Share on other sites More sharing options...

What you have to account for is the increased height - the 190/55 is a taller tire than a 180/55. The bike will steer a little quicker (not a bad thing - many people drop the front end to get the same/similar effect). The change could also make the bike slightly less stable. 1 Link to comment Share on other sites More sharing options...
RandyN Posted May 15, 2019 Share Posted May 15, 2019 If you go with a slightly taller tire please let the rest of us know your experience. As said it most likely will make it quicker to turn in but it could throw off the ABS/Traction control system because of a larger circumference. I'm not knowledgeable enough to say that it will do that, but it might. Anybody had any experience with that? Link to comment Share on other sites More sharing options...
jsp Posted May 16, 2019 Share Posted May 16, 2019 Tire engineers spend a lot of effort perfecting tire profiles. A 190/55-17 is designed for a 6.00 to 6.25 inch wide wheel. Now put that tire on a 5.50 wheel and you have drastically changed it's profile. The center becomes noticeably more pointed, reducing stability and it becomes a wobbler on a rain grooved freeway. It also causes the center to flat spot quickly causing an uncertain feeling as you transition entering corners. Another change in the profile is the edge of the tire becomes unusable. The last inch to inch and half is now at too steep of an angle to be used. If you want to try something different, try a 180/60ZR17. john 1 Link to comment Share on other sites More sharing options...

The difference between 6" and 5.5" is 1/2". Take a 190/55 and squeeze the bead 1/4" in on each side. The profile of the tire barely changes in any way. Go to any roadrace track in the country - everyone from novices to pros are using the bigger tires on their 600s. Do you need that extra performance on the street? Nope, not at all. Might as well stick to the cheaper 180/55 size. But it absolutely won't hurt anything to try it. Oh and FYI - the Pirelli 180/60 measures out at 190mm - It's just a renamed 190/55. 2 Link to comment Share on other sites More sharing options...
koth442 Posted May 17, 2019 Share Posted May 17, 2019 So long as tire clears the chain, a 190 rear will be fine. As noted above, many track guys run 190/60's or 190/55's on 5.5" rims for extra contact patch. 1 1 '15 FJ09 Link to comment Share on other sites More sharing options...
bushman57 Posted May 24, 2019 Author Share Posted May 24, 2019 Thanks for all the answers! I will definitely report back when I try out a 190/55R17 It won't be much longer. I've already raised my shock tubes up 10 mm. So after the rear tire install it should turn in even quicker. Link to comment Share on other sites More sharing options...
kilo3 Posted August 4, 2020 Share Posted August 4, 2020 Bumping this thread. I had a line on a local chap slinging michelin road 5's for $400 installed out of his garage. Sounded good so I took the wheels off and headed over. He had a 180/55 rear tire in hand, looked at me, looked at my old tire, went back and swapped it for a 190/55. He said it would suit me better. Not sure what that means but no rubbing issues and no concerns. Yeah the tire turns in better, but all new tires do. I don't know, seems fine to me, happy new tire day! 3 Link to comment Share on other sites More sharing options...
Dodgy Knees Posted August 4, 2020 Share Posted August 4, 2020 How was the wear on the old tyre.? Not sure why he would do this, should be OK though. 👍 Link to comment Share on other sites More sharing options...

I was just as confused but don't know enough to question. Looked like he knew what he was doing by the size of his race trailer. Link to comment Share on other sites More sharing options...

kilo3 Posted August 4, 2020 Share Posted August 4, 2020 Whoa, I got a blazing deal with the bigger tire. Whether or not that's better, sounds like an oil thread to me. 2 Link to comment Share on other sites More sharing options...
draco_1967 Posted August 4, 2020 Share Posted August 4, 2020 I ran a larger rear on my FJR a couple of times (same stock size 180/55). I noticed very little change. No fitment issues either. Link to comment Share on other sites More sharing options...
