Hey guys I'm having a problem with steering my stand up wheelies. I'm not new to it so I do know about bp body shifting (leaning). Its a 06 cbr 1000 I was find with changing lanes passing cars all that good stuff. Just the other day I went to a 190/50 from a 190/55 rear tire. Now it seems like a cant steer it to save my a$$ what going on. Also I run my tire pressure around 34 pis cold.

 

psi should be around 20 to 25 that might help a little

 

20 to 25 psi for a lot stunting! all there is to 55 is that the wall is a bit bigger, (higher profile) try to go higher psi

 

My buddy runs 22ish psi in his, yet i run 35 in mine, so psi wont always make a difference, its more rider preferance. However you could certainly try and play with it a bit and see if it helps.
