Default Best 19" Tire Size for Optimal Comfort?

I've been going back and forth about this for a while now about purchasing wheels and since my saving acount dropped to less than 4%, I decided to start moving money but I digress.

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.

19's will not be as "comfortable" as 18's, and 18's are not as comfortable as 17's. More sidewall = more comfort. Less sidewall = less comfort. 19's and 20's have the least amount of sidewall, 17's the most.

I got that part down, it's just when it gets into specifics that I get lost. I was going to get 18's but since I'm not dropping the car, I figure 19's is the other best option of closing in the wheel/fender gap without sacrificing too much ride comfort.

Get 265/35/19 and 235/35/19 with 19x8.5 up front and 9.5 in the rear here are some pics of my car with that set up and it rode fantastic, but then again I did have PS2s on it, which are the best tire by far you can buy.

The greater the overall tire difference from stock, the more your speedometer/odometer will be out-of-spec.

Also, the 19" may just make your car all the higher, and not fill in the wheel-well-gap unless you drop or go with a bigger tire that increases overall diameter without rubbing.

Thanks for the suggestion guys. Which one would have a bigger sidewall?
225/40 or 225/35? I'm assuming this is for the front?
265/35 or 265/30? I'm assuming this is for the rear?
