What are the most likely effects of mixing the front and rear tire brands? Currently I got the oem Yokohamas both front and rear. The rears needs replacing and lods of thread left on the front.I'm thinking of trying out Eagle GDS2s for the rears, which have good reviews for both wet and dry. Just wondering if it would have a significant impact on grip and performance with different fr/rr setup. Perhaps a little like mixing different brand 'Duracell' batts?
