Bump OLD THREAD
Well I am actually looking at running 275-40-17 on my track rims.
The OEM tires are 195-40-17 which make them have a diameter of 24.7
The 275-40-17 have a diameter of 25.7, which is only 0.50 bigger on each side, which should clear the strut perch
Also I running a 17 X 9 with a 17mm offset, 5 x 100.
Its a Drag DR-31.
This will also be combined with 13mm of spacers that are used for my big brake kit.
Which equals a 17 X 9 with a 4mm offset, or next to zero!
I will keep posted on if this works or not.
