The EVO has a treadwear rating of 240 and isnt really comparable to the Toyo R1R, whereas the RS-R has treadwear 140 which is the same as the Toyo R1R.
Through our own testing in the Drift Australia series we have found that the 595RS-R offers almost identical grip (if not more due to lower void ratio) than the Toyo R1R, they're also both about the same price - for example: 235/45R17 RRP R1R=$323.00, 595RS-R=$325.00
