i have never used any other size then 190/50 for the life of my RC51 , in the past i heard riders using 180/55 for faster turning , 190/55 is the tire used now days , will the 180/55 work on my 02 ? 190/55 how much taller is it over the 180/55 , ,, please only info , im so new to asking ??? on a forum ,
i found this --- A 190/55 is roughly 1/4 of an inch taller than a 180/55. The 180/55 still has better turn in because the profile on the 180 is steeper/pointyer.......I run the 190/55 because its the best comprimise between the contact patch of the 190/50, and the great turn in of the 180/55 ---- i tried all 3 sizes in the BT-016, liked the 190/55 for my 929. turns in faster than both 190/50 and 180/55. And that's not from rear ride height change since i adjusted my Fox TCR shock length to compensate. I'll guess the 180/55 is too narrow for 929's 6" rim and that flattens the profile. 180 noticeable less traction on rear braking or botched downshifts. 190/55 also best bump absorbtion when leaned over, feels less skitish on rough pavement. Tire life was about the same across the three: 2500 miles. ...alex --- I've ran the 190/50 that came on the bike then switched to the 180/55 when it was time. It definately turned in noticably quicker. A lil too quik for me on the street anyway. I just put on a new Michelin PilotPower 2CT 190/55. Racked up about 1200 mi. so far and I agree with MAC4LIFE it is the best of both worlds. Turns in a little quicker without sacrificing the corner stability that the 190s bring to the table.
thanks for the info and time you took to look it up for me , have a great night
Not a problem, anything for a fellow RC rider. I reread that thread every time I need a new rear when I see the price diff from a 180 to the 190/55. BTW every time I get the 190/55. Oh yeah one should be coming tomorrow from our friends at STG.
And it was a PITA, to find while on my phone.

I've currently got a 180 mounted on mine but it's a Q2 which has a wider profile than most. I've never measured it but I know most manufacturers don't follow the exact measurements on the side of the tire. For example, Dunlop makes the 211GPA's in 190/55 and 200/55. 600's use 190's, 1000's use 200's. So where does the bastard mid size RC51 fall with it's 6" wheel? I've got a couple 190 GPA's, when I finish a 200 off I'll throw it on and see the difference.
I can say that the difference between a 190/55 and a 200/55 on a 1000RR is amazing. Getting on the gas with the 190 and the rear end squirms a lot. The 200 stays planted and drives hard out of turns. This is all on track though.
thats where i got my tire info from.. i am currently running a 180/55 tire, but unfortunately i dont have anything to compare it to because it was what came on the rc51 when i purchased it. what i can say is, i am definitely leaning towards the 190/55 when the time comes to replace it because it does feel a bit squirmish at times. i like the sound of more tire contact with the road =P
