I have a set of silver Rota RB's with carbon fiber caps wrapped in new Yokohama Advan a032R's.
-Wheels are 13x8 with +4 offset. Tires are 215/50/13 and have been driven on for about a week.
-Two of them have some very minor rash on the lip (just needs some polishing to get rid of it). Other than that they're in new condition.
These tires are considered street legal race tires and provide the maximum amount of grip for maximum performance. For the tires themselves I paid just under $800 and for the wheels after shipping was just over $600. A combined total of $1400 new.
