Sorry mods if I posted in two places, but I realized this might be a more appropriate place to post and might get some help here as well.

I decided to get some 19" wheels for my 2IS, 19x8.0 with 40mm offset in front and 19x9.5 with 40mm offset on the back. My car isn't dropped and I probably won't drop it, at least not anytime soon. I also don't want to cause any rubbing so I'm sticking with 40mm offset even if it's not flushed (doesn't worry me much whether it's flushed or not).

I don't really want to compromise the ride comfort of my car (that's why I'm not lowering at the time) and my question is, what's the best tire size for a 19" tires to get for the most comfortable ride with a 19" wheels as possible? Some say the bigger the tire, the more comfortable the ride is, if that's true then I guess the question becomes whats the biggest tire I could get without causing any problems such as rubbing, etc...?

Thanks for any the help, it will be appreciated.

What are the factory tyre sizes?

I'm running 19" wheels on my Soarer (8.5" front and 9.5" rear)... 235/35 and 265/30. They do put more feel through the steering wheel but I usually have my tyres pumped up to about 38~40psi when cold.

i thought the original diameter should be either 205/55/16 size or 225/45/17 size....

instead of comparaing to the option sport package spec?
