Did a first test fit of the rim today.
Never mind the 255 tyre, the rim itself doesn't fit without a spacer. FML
Here's a pic:
Tein SS strut obviously on the left, rim on the right
Here's how my set of 17x9 +42 Mach V Awesomes sit with 245/40/17:
So, if I put on a 3mm spacer, the 18x9 +45 I'm trying to install would effectively fit the same as my Awesomes.
Looking at the pic above, will a 255 tyre fit OK in there?
