Will this rims&tyres scratch the fender?

Its Avus mk2 18 rims from s8,the tyres are 245/45
Will they fit ok under urs4 with -30mm h&r springs?

Someone?

I would use this to compare the total height of the wheel+tyre with what you have now, so you know approx. where it will sit in the arch and if you are clear of any suspension components.

And this to compare ET.

Here is from calculator,the other site i dont know how to use?

My current set up is 205/55 r16,and i am found rims with 245/45r18

Well, from that your car will sit 23mm higher and the gap between the arch and the wheel will be 23mm less. So ig you want to lower your car by 30mm that means that the gap between arch and the wheel will be 52mm less than it is now. What I found out when looking at my s4 is the gap between the strut and the wheel is quite small, so check that.

I belive that this tyres wont fit then,argh...Thanks for info mate

Just found this http://www.willtheyfit.com you can put et and width in as well, and it shows in comperison how it will be.

Any toths?

So from that. Arch gap will be 22.9mm smaller (52.9 when you lower it). Clearance between the wheel and strut housing will be 16mm less (wheel will sit closer to strut) and wheel will sit 3.7mm deeper in the arch.

If the wheel will be 16mm closer to strut housing, check if gap between wheel and strut (height wise) is 22.9mm etc. See what happens when you do a full lock to either side, check all the gaps.

So get the ruler out and get measuring.

Impressive stuff hunker.

I don't think anyone on here runs 245 tyres. Only thing you can do is get someone who runs the same setup as you, and ask nicely to do some measurements.

But I doubt you can fit 224/45, because I was looking to fit 225/50/18 and strut would be in the way height wise, so I have to get 225/45 instead.

Have a play with that calculator, you might be able to fit narrower tyres or lower profile tyres.

Even if you can get the height right, most worry will be the gap between strut housing and the wheel.

Well,i am going then to buy rims w/o tyres.I belive it will sit nice on my urs4 avant,its avus mk2 from s8

And if the gap is too small, you can always use some wheel spacers to sort it out.

You have build thread of your urs4 by any chance?
