Federal Semislicks are on. There is a bit of rubbing in the rear with the 255/35-18 on the 8.5" wheel since I am currently using a 20mm spacer. Once removed it will be fine. Clerance on the front is great, and to me this actually looks like the perfect size (245/35-18 on 8.5" wide with 5mm spacers), they are however a bit wider than the Toyo T1R 245/35's.
Only downside is that the weather turned a bit cold so I have not been able to try them, only a short drive but initial feeling is good, they are pretty safe in cold/wet condition compared to the CUP and R888, which probably means that they lack the warm track grip of the other two.
