If you have them post pics and what you had to do to make them fit. Ive seen a couple cars on google but no info given on what they did to make them fit. Im hoping someone here has them and can give me more info.

You've gotta do a flare to make it right. Car in picture has 345/35/18's in the rear, 335/30/18's in the front, all on 18x12 wheels. The 345/35/18 has similar overall dimensions as a 345/30/19. The picture is during a left turn so the fender is rolled out a bit on the right hand side of the car.

You *can* get 345's on a 12" wheel under stock fenders, but it rubs the SHIT out of the inside of the wheel well.

Im looking at putting them on 19x11 wheels. Ive seen a ton of pictures with 18x11's and a 345 30 18 tire.

Yeah 345 is WWAAAYYYY too big for an 11. especially with a 30 sidewall. A 315 is pushing it.

345 on a 12 is honestly not enough wheel.

A 305 would be ideal on a 11" rim. Use the correct ET, and it all fits and clears nicely. Plug + play.

Dimora managed to install 335mm wide rear tires, but had his 10" roush wheels widened to 11 7/16".(by weldcraft). To make it all fit, barely, he had to remove the protective covers on the top ends of the rear shocks, (gained aprx 1/4")... and also re-locate the bump stop assy. (So it won't rub on the inner wheel well). His is a 2008.

This is a 325 30 19 on a 19x11 with no issues. The 305 30's just look too small to me.

You say no issues. I say lots of bulge.

I suppose it depends on the application.

You think the nittos have bulge? They look good to me. A lot better than the 275 35 20's i have on a 20x10 wheel now.

Yeah. Most low-profile summer tires are designed to fit like this, for best contact patch, sidewall shape, pressure, etc. I'm speaking from the point of view of someone who does track and autocross events however. If you're not into lateral G's, I suppose it doesn't quite matter so much.

My Nitto NT-555 285/30-20's are perfectly flush with my 20x10's. This is about the best photo I have of the sidewall. As you can see they run really narrow and thin. Ended up lowering the car again after I got them mounted because there was so much fender gap.

They are nitto invo's

I have seen 315 Nitto invo's... on a 11" wide rim... but that was 20" wheels, and it looked and worked good. Not much side wall on a 20" rim, and not my cup of tea.

I have 305 nittos on 20x11"s. Pretty straight sidewall, another 40mm of section width would be a pretty solid bulge.

Edit: Did some research, go with a 325/30R19 if you already have the wheels. The measuring wheel for the 345 is a 12", which means it is a bunch wider than the 305's that I have, as the measuring wheel was an 11".

And for nittos running narrow, it's not that they run narrow, you can't lie about numbers. The measuring wheel is a much more important piece of info that people seem to ignore. A tire on a 10" wide wheel will measure smaller than if you mount it on an 11" wide wheel. Depending on the tread width, it could be a reasonably big difference.
