Weight is important, but I wouldn't get too hung up on it...
I ran 235/40-17 NT01s on 17x9 6UL wheels (36 lb) back to back vs. 225/45-17 RE71Rs on 17x7.5 heavy factory wheels (42 lb.) at Palmer...

Yeah, they should feel similar. Flat torque up to near peak hp is a good feeling. My 2.9 Cayman had a torque curve that had a broad peak centered on the midrange and fell off more noticeably with...

I was initially fine with the factory dampers, though over the years/miles I got tired of the high-speed compression damping that IMO makes it *feel* a bit more sporty/go-karty initially. Ultimately...

We have both guy A and guy B running 235/40-18 tires, one on a 9.5" wide wheel and one on an 8" wide wheel.

All I'm saying is if I'm "guy A", I'd be running 245/35-18s on his 9.5" wheels, and if...

Don't worry... Peak power still at 7000rpm, it's not like it's falling on its face above 6800.

FWIW here's my effort at plotting my '17's dyno results (178rwhp on Dynojet) vs. the dyno plot shown on the '22 BRZ dash scaled by the same rwhp/hp factor of 178/205 = 0.87:

The wheel width range to run a 235/40-18 is 8" up to 9.5". So that tire size on 8" or 9.5" is legit, just at different ends of the envelope.
For maximum lateral grip and responsiveness, you would...
