Aftermarket alloys on a C70 Coupe

[asbo1980]

I have a 2000 Coupe C70 and have been meaning to change the wheels for a while.I have the choice of two sets of alloys and just wonderd which set would fit best without any rubbing, problems etc.
There a set of Black Momo Arrows 17 x 8 and a set of Chromes 205/45 ZR17 88W.
Your help would be appreciated, thanks

if you use this tyre calculator it will show you how the new tyres compare to your factory ones so you can see if its likely that they'll rub, but you also need to take into account the offset of the new alloys compared to the factory set. If the aftermarket alloys have a much bigger offset than the factory wheels then even if you are running a smaller width/profile tyre, because the wheel will be sitting further away from the hub they could still rub

PS just noticed, a 205 tyre on a 8" wide wheel is going to be quite undercut. You might need to either go thinner on the wheel or wider on the tyre to match them up right

i am running 18s with 225 40s and have no problem at all other than full lock but it rubs with the standard tyres on it

Provided the wheels have a PCD of 5 x 108, what is the offset of the wheels you're looking at? Without that info, any advice on tyre sizes etc is fairly pointless.

Still have some tasty 19s for sale.
