After driving on my new wheels for about a month now, I've noticed a couple things different about the handling.

Most notable is the squirminess accelerating along sweeping on-ramps. Its seems to get kind of bouncy and squirmy as I push it to 80mph (TC/VDC off). When I'm doing this, I'm not close to losing control, but it just seems to be less stable than before.

Has anyone noticed this with larger/wider/different offset wheels?

FYI: I have 245/35/19 and 275/35/19 toyo t1s on 19x9.5 +22(f) and 19x10.5 +22(r) rims. Tire pressure at 35psi on all fours, stock suspension.

I'm thinking of putting my stock wheels back on this weekend, and do a canyon run to compare.

 

New tires will feel a little squishy until you get a few miles on them. That and the Toyo's are probably a little softer compound than the Potenza's.
