| Dickie,
You've really got me thinking now....
Here are some thoughts that I have currently:
- I have never had a 5in rim so I cannot comment about 190/50 on that size rim (I don't think it is recommended?)
- I was comparing a 190/50 on a 6in rim against a 180/55 on a 6in rim
- 190/50 tyre height is 190 x 50% = 95mm
- 180/55 tyre height is 180 x 55% = 99mm
- Perhaps the 4mm additional height of the 180/55 results in a tiny increase in head angle and results in a perceived quickening of the steering?
- Although a 180/55 is not recommended for fitment onto a 6in rim, the "spreading" of the tyre is only 0.25in per side. I would expect that this change in angle of the sidewall would not be transferred to the rolling profile of the tyre since the connection between the sidewall and rolling profile is "flexible" (in engineering terms, the angular deflection is not carried around the corner as there isn't 100% moment continuity at that joint)
- my comparison was conducted by comparing a worn 190/50 against a spanking new 180/55
- part of being in the club is that we are all allowed to have our own opinions, and those opinions stimulate healthy debate - so no need to worry about getting chucked out !
