i ended up with 35"12.5R17 cooper on 17/8 pro comp...
everything is difficult in germany...
in order to get the tires approved i had to make sure they would not stick out (even a hair) over the fenders.
to make that work i installed some wider flares from xenon. i like that they are rubber and won't brake when running them into a rock like the bushwackers do...
There is no instructions on how to take off the stock flares, so figuring that out is the biggest challenge. After all, I didn't want to mess up the sheet metal. Once the inner fender is removed, the outer pops off easily. The plastic mounting clips broke during this process, but they are not needed any longer.
The inner fender is temporarily put in place to be marked for trimming at the sheet metal edge.
The Xenon fender simply gets bolted on with the provided hardware. Then the inner fender is attached.
The rear flares get mounted accordingly, only that the existing holes need to be drilled out slightly and revit nuts are installed with a provided tool.
The provided tool proves a little soft and wares out quickly. Another pair of hands is very helpful for the installation of the revits!
Then the flares can be bolted on. The entire installation took me about six hours.
