I am limited with tire size for my gnX wheels. 16 x 8. 255's is about as big as I can find for the rear. Only a few make 255's. Anyone have good things to say about Sumitomo tires. They have a HTR Z model in 255's and 245's which is what I need. Also, what about BFG g-force sport in 255's. It is not a KDW model. It is listed as a sport model in 255 and 245. Are these as good as the KDW's.
