I guess this is a physics question of sorts...

I recently replaced a 7 year-old set of Sumitomo HTR-Z IIIs with Hankook Evo2s and while I'm enjoying a quieter and softer ride, I've noticed a significant (and new) delay in s steering response.

Turn the wheel...wait a second...car turns in.
Mostly noticeable under enthusiastic canyon driving.

So here's my question: The tire place inflated the tires to around 38psi all around.
I deflated them to 34 F / 35 R (cold) which was closer to the 32psi I'd been running on the previous set of tires.

I will experiment with tire pressure (and reply with my findings) but do you think inflating or deflating the tires will give me better steering response?

Thx in advance...

I never owned a set of of those v12 evos but I heard they have very soft sidewalls.

Mr Dave

...meaning they don't have as sharp a turn-in?

less feedback due to soft sidewalls and s2k likes stiffer sidewalls. There was another thread here recently about less steering response after a tire change. I doubt changing tire pressure would do much. The tire compound isn't going to change. adjusting tire pressure will change contact patch and adjusted accordingly to get maximum grip out of your tires, I don't know about steering feel through tire pressure.

I don't know much about your tires besides the stuff I've heard about them. Just saying it could be the tires and changing tire pressure won't do much.

edit

I may not have answered your question directly. But yes you can loose turn in feel because of less feedback from soft sidewalls but the effects of the tires are not limited to turn in. As you felt has a softer rider all together. I think s2k has enough absorption from the stock suspension setup that you really should avoid soft sidewall tires all together.
I don't believe I know enough to get too technical with my explanation. Hopefully someone with more experience, knowledge can chime in.

found the thread. https://www.s2ki.com/s2000/topic/1082024-lazy-steering/

Mr Dave

Thank you for the response!

I read through the thread you linked...Yikes -- I was hoping it wouldn't be something I have to live with.

Mr Dave

Ahhhhhhhhh
