Purchased 2006 lexus is250 w/ bridgestone potenza re92 in nov 2005 - tires do not provide adequate traction in wet or dry driving conditions. when turning right, vehicle tends not to straighten out without increased effort. ability of tire to hold up under semi-wet conditions is very bad. tires are 3 5psi front (225 45/17) and 37 psi rear (245 45/17). *jb
