15x10, will they fit ?

[E30Jim]

I'm looking to widen my RS's by swapping the 5.5'' rear barrels for 6.5'' ones. My question is: can I fit15x10 et25 on my E30 without spacers ?

If they fit, do you know where I can find some 215/45/15 tires in America ? Nobody seems to offer them...

dunlop has 215/45/15's
and also toyo proxes T1-R

also try looking for 205/50/15's

Why don't you measure if you got a inch of clearance there? and irc, you need about et 20ish.
What are the specs of your RS right now? 15x9 et 38ish?

The car is stored and I can't go see it right now. At the moment they're 15x9 et00 and if I add 1'' to the rear barrels they'll be 15x10 et25.

no they wont, the will be et13.

changing the width x amount only changes the centerline x/2 which is where offset is measured from. all you ever need to know:

+1" lip = -12.7mm offset
+.5" lip = -6.35mm offset
-.5" lip = +6.35mm offset
-1" lip = +12.7mm offset

+1" barrel = +12.7mm offset
+.5" barrel = +6.35mm offset
-.5" barrel = -6.35mm offset
-1" barrel = -12.7mm offset

-i thought you wanted to change the lip at first, thats why i asked if they where et 38. But you should be good to go with et12,7.

Ok I was thinking that adding 1'' to a et00 wheel will give and et25.4. SHit I'm confused..

Exactly what I was going to tell him. Glad to see there's someone who isn't scared off by this stuff.

can i get some quote recognition?

it's not too confusing as long as you consider offset is measured from the centerline of the wheel. when narrowing/widening the wheel from 1 side of the centerline (i.e. new lip OR new barrel) you are only moving the centerline half of the amount changed.

[E30Jim]

Thanks a lot guys. So they'll be 15x10 et13

Now I need to find a good source for some 215/45/15.

If they clear the brakes already, giving them a wider lip won't affect the clearance?

... dude, if you got an apple and i give you a banana. What do you have then? A apple and a banana...
1+1=2, why would it affect the break clearance if you add a bigger lip. The only thing that the wider lips bring with the, its a helluva lot more awesomeness and clearance "problem" between the fender and lip.

Thats my point? I'm confused why he's asking if he would need spacers if all he is changing is the lip size?

I think my question mark confused you lol

He's changing the barrel size and I believe he wants to know if he can still clear the rear strut.
