I run a car tire on my VTX1300 since 2011. Can't wait til the back tire on my Valk wears out so I can switch. But I will put a GW rear wheel on since it is a 16" wheel and tire choices go WAY up when you go from 17 to 16 inch. Needs to have a spacer machined to work tho but it is very doable.
The first tire was a Pirelli P4 205/75-15 and I had to replace it due to picking up a nail too close to sidewall. I got tired of putting air in it every 2 weeks so I replaced the Pirelli with some cheap tire thats sized 205/70-15. The height difference between the 2 tires is small but I did notice it. It needs more effort to turn than the 205/75.
Skinnier tires require less turn effort than wider tires.
Taller sidewall tires net more rubber on the road in a hard tire than shorter sidewall tires. Short sidewall tires also require more effort in a turn due to "climbing" up on the edge of the tire in a lean.
Sidewall height is EVERYTHING when it comes to which tire works better than others. The higher the sidewall the more the tire will "squat" in a turn and the more rubber you end up with on the road. The 205/75-15 in a turn, dragging pegs and making sparks, nets almost exactly 50% of tire width on the ground.On a 205 thats a lot of rubber. I actually have a pic of the bike doing just that on the dragon.
The 205/70 has a little less rubber on the road under the same circumstances. My brother-in-law rides behind me and he brought it to my attention. He rides a harley so he is usually behind me. Especially in the curvy stuff. I didnt realize when I changed tires I asked for a 70 series instead of the 75. Thought it was my imagination about the amount of increased steering effort til he asked me about the difference in tread on the ground.
The picture takers on the dragon are an excellent source of info when you examine the on-the-ground tread when the bike is in a hard lean. I have seen the 60 and 55 series on bikes that have very little tread on the ground in a hard lean. Nowhere near as much as my tires have under the same circumstances.
Any other questions just ask. I will be happy to tell you my experiences. They do ride different but if you choose the right tire it makes all the difference between choosing one that works well and choosing one that works but just not as well as others.
Hope this helps
