Thanks all. I'll keep them at 30/39... although 31/34 seems to be the most common thus far...

So, I just changed mine yesterday after almost 3 weeks at factory race setting of 36/44 to 32/35. Wow, what a difference! The ride is soooo much more smoother and a lot less jarring. I much prefer the comfort setting. It's like I am driving a new car again 3 weeks later! Glad i did it.

I changed mine from a ridiculously overinflated value of about 41/49 to 34/37 (I like to keep it a little on the firmer side). Not sure why they came so overinflated as the comfort setting was actually selected in the PCM.

I also have the Sport technos, which are wider than the standard tires in the rear. The manual does not seem to list separate pressures for them, though I'd think they should since the dimensions are different, no?

I'm playing around with my tire pressures as well now (19s on a C2), inspired by this thread. I lowered them to 31/39. The difference from how it came from the dealer - which I think was 36/45? - is huge. I can now actually drive over spots (like pavement- > brick stripe -> pavement ped-X-ings) on the road through town here without feeling like I have to slow down to 5mph. Muuuuch smoother.

I think I'm going to push the fronts back up a bit - maybe to 32/33 as well - and probably lower the rears a hair further to something like 36/37), but it's definitely worth messing around with. And I guess I'll see if my wife notices since that would be the real confirmation.

I also have Sport Techno's and the dealer Technician used same pressures as listed in manual (I went comfort, full load).

Thanks for that.

Thanks to everyone for this. My car now rides much better and there is far less road noise.

Nice read, and many thanks for the link!

Nice find! I'll have to try comfort/half-load if that's the general recommendation.

I think the ride is super even with the full 36/44. I wish they would have named the "comfort" setting something else, lol. Makes it sound soft. But if it provides better still handling, I may have to try it.

I can get a 2 to 4 lb swing when the tires warm up, and when driving on a hot sunny day in FL, it can be on just the side the sun is shining on.
