running on 225/45 19z

and rear is 245/40 19z

 

You could use those tires on the Advans. When you're mounting them on the car, you can test fit the Rear on the front and see if it rubs or not.

the fronts are 19x8.5. The rears are the 19x9z

 

That's alright. The OEM 18's on the first gen coupes are 18x8 all around with 225/45 front tires and 245/45/18 rear tires.

You could always go with 225/40/19 all around when its time to replace the tires. Or 245/40 if they fit the front.

Are the 225/40/19 skinnier in rubber size in comparison to the 245/40/19

 

They are 20mm smaller in width and have .32" less sidewall.

how did the decrease in 20mm width happen?...i was thinking the width would at least stay the same..or close to it

 

The first number in the size of a tire 225/40/19 is the section width of the tire in millimeters. So 245-225= 20. 20mm is the equivalent of about 3/4"

The sidewall is only .32" smaller.

Thanks for clarifying! This opens up a lot of doors in my brain now haha

 

yeah, there's many many many factors that play into having the perfect setup for your needs.

Thats the thing with ordering JDM wheels...it can take a while to get to my front door. How long do u think itll take...i read in that one forum that kid was waiting for two months! DAAAAAMN! haha but that thread was put up about two years ago...so things might have changed....i hope

 

it can take anywhere from 2-6 months when ordering JDM wheels. It all depends on who you order it from and if they have their **** together.

But on average, it takes 8-10 weeks. Where do you plan on ordering them from?

Vivid is a legit company. But i'd see if any of our site sponsors can get them and save you a few dollars
