I'll be putting 315 30 18's on and they will fit with little hammering. I know plenty of people who have installed 315s and did nothing. My car is lowered 1.5" and shouldnt have a problem. IMO the 45's are too big. yes softer ride but with a 18 you need to drop to a 35 maybe a 30. and 17s a 40 at most. it will look better and fit easier. A 45 is just too damn tall to me

Well mine are315/40/18 so mine are a tad bit smaller. I would have gotten a 35 but Nitto didn't make NT05r's in this size. I wonder if I run a 35 tire up front and a 30 out back will there will be any issues. I still have time to return these but only other tire to really get is the NT555R's.

The 30 on the rear will probably have less sidewall. It will look like the fron tires are taller than the rear. I didn't run a spacer at all. No rubbing on the inside at all. Even with someone in the back seat. It would actually tuck a inch or more of the tire with someone in the backseat.

Go on there, put in the sizes and it'll give you a good idea of the difference between what your front and rear tires will be.

I don't get how it is that some people do roll the fenders and then some say they don't and a get a perfect fit. NovaCain383 any way you could walk me through the process of rolling the fenders, I have everything but a fender roller but Im sure I could get one.

Yup lowered around 1.5 or 1.2 i believe but i bought rims 18 x 9.5 front and 18x10.5 rear so i'm deciding on the tires. I have heard so many people who have bought the falkens for 59 each (its driving me nuts i didnt see that) but anyways i need tires just deciding on the size

So I just remove the wheel, attach the fender roller while and start rolling while applying heat with the heat gun. Do I have to have jack stands on all four corners to have the car suspended evenly? Ill be working out of my garage that's why I ask. I was thinking of doing the same, rolling them enough just have them clear.

Why not send them back and go with a different brand in the size that you want? That could be easier and might not have to mod as much just to make a certain brand fit..

Just set the back on stands, do a little at a time until you get it where you want it.

Well got my rims today and got the tires mounted. Did a test fit on the car and no issues except for the inner fender is really tight at h 9oclock side of both the fender wells. Did a little bfh mod but its late and I'm tired now so ill work on it tomorrow but it seems to clear good enough. I might still have my buddy roll the fenders a bit just be on the safe side.
