what tire is this in the middle and would it be okay to ride on the streets?
Nope, that's right 190mm, sidewall height is 55% of that =~105mm, whereas a 190/50 has sidewall height of 95mm. Put on a 17" rim, you've got an overall diameter of 25.27in for the 55 versus 24.48in for the 50. Steering shouldn't be affected as it's the same width (?)...catman said:A 190/55 tire would be taller. It will steer quicker and be more curved.
If i remember correctly ??
The second number is the percentage of the profile hight /to the total with of the tire ??
Someone correct me if I'm wrong.:nuts:
