i thought i scored today. got a DIABLO SUPERCORSA SC for $30. keep in mind that im low on cash do to a broken arm. has 75% tred on it. its super soft and feels really good on a ride. (have broken arm only riding at 30%) is it bad to run a 190 55?? i do track days and like to ride aggresive when im not in a cast. also i have a bt-003 on the front. is it bad to miss match.. thanks guys

 

"ideally" tires should match. But I look at it this way, which is worse, a tire that has tread that may not be the recommended size, or a worn out tire? I'd rather ride at 30% with a mis-match than not al all.

i mistakenly installed a 190x50 on a 5.5" rim thinking it was 6" and it works but changes some things. Basically you're squeezing the tire a little (beads in) which increases the the slope of the tire near the edges. I ran it for 1000 miles and found that when I leaned it over to the end point of the OEM size, it would start sliding. Despite this slipping, upon inspection of the tire after rides, the chicken strip indicated i was not to the tire edge. I don't know how much more lean i would have had to employ to get to the tire edges because I didn't have the ***** to try it on the street.

if I were using it on the track, I wouldn't be adverse to a little more experiment with the lean angle of the larger tire on the OEM rim, but i took it off for the road because I didn't feel I could anticipate what it was going to do after slipping started.

Also, my experience is with a bto-16 and your pirelli may be a different shape and be better or worse than what i experienced. I started out with cold pressure of 28. For the track, you may want to go a little lower, maybe 24 cold and see how it feels and looks when you're done with a few laps.

 

its very very bad. but not as bad as riding with a broken arm!!!
You are obvisouly insane, so in your world, if you put both things together its probably a very good idea.

More seriously, as noted above, your unlikely to notice much difference riding moderatel sanely. It will change the profile being on a narrow rim than intended and probaly be an overall taller tire. So it will change some handling characteristics and probably add some ride height which isn't all bad usually on these bikes.

good luck, but riding with a cast? hope its not in traffic.

 

haha thanks guys ... sorry for the delay. hit some twisties with it pressure at 22 psi. i was inches from draging a knee. could not get it all the way down. the grip was great way better than the old tire. its that soft compound. slid a little on painted lines. soon as it hit the road back on its path. most diffrence i felt was it being naked. anyways like the tire. way diffrent angle when turning. had chicken strips of half inch. i normaly have none. would not reccomend it but like nath said better than what i had.. thanks guys. cast come off in a month... ready for the track...

 

sounds like you're having fun. Almost got the knee down,huh. Good feeling. Either wait til you get the right tire or get thicker pucks,hahaha, or maybe you don't have pucks? whatever, just proceed with caution or if your going to take risks, take only calculated ones. Have fun.

 

22 psi for a SC is too low. pirelli tires have soft a carcass and need a little more pressure.

the problem with the 190 is the tire rubbing on the singarm ( besides pinching a tire for a 6" rim onto a 5.5" ) compound that with low tire pressure and you 'may' find yourself in trouble.

SC ( 1, 2, 3 ) SC 1's don't like a lot of heat cycles, 2 &3's are ok - they just take a bit to warm up.

in a 120/180 combo the SC 2 is probably my favorite tire.
