Are these wheels/tyres an good for my car?

[MMT]

It's a 99 996 C4

Front 225 40 R18 - 8" x 18" ET 50
Rear 285 30 R18 - 10" x 18" ET 65

Is the rolling circumference close enough and are they likely to rub anywhere?

Thanks

Thanks for your reply.
I have done a bit more digging and found some info in Total 911 magazine showing the 993 C4S and turbo both had this set up. My worry is if the rolling circumference is out too much, can it cause any diff issues - winding up?
The ET offset is correct for my car I believe. A closer combination would be 295 30 as far a rolling circumference. It's just whether there would be any rubbing on a C4.

Ok thanks I'll try that. 👍🏼

Thanks for the replies.
My C4 currently has this set up, but they're winter tyres.

F 8" x 18" ET52 with 225 40
B 10" x 18" ET65 with 265 35

I've seen some wheels with half decent tyres for sale, but the back tyres are slightly bigger
at 285 30.

The 265 35 is 0.2"/0.8% bigger than the front.
The 285 30 is 0.4"/1.6% smaller than the front

The 285 is also 0.8" wider than the 265 too.

Great, thanks for your replies.
