I recently replaced my factory 20 in tires with some Yokohama Parada Spec-Xs from the local Discount Tire. With the TPMS aggravation, mounting, force balancing etc, it came to about 1000.00. I also ended up going +1 on the size.
After putting a few thousands miles on them, I definitely can say that outperform the factory tires. They are quieter, and have better grip, both wet and dry. The 300 has a fat ass, so it needs it
