RBbonfire Posted December 31, 2017 Share Posted December 31, 2017 Just bought for my wife a 2010 GS350 with 18in wheels and new Dunlop Signature HP 40 profile tires. The ride is much harsher than any of my previous Lexus vehicles, including her 05 GS300. She blames the 40 profile tires. Would changing to a different tire help or am I going to have to change to a 17in wheel with a higher profile tire? Thanks for any recommendations.

RBbonfire Posted December 31, 2017 Author Share Posted December 31, 2017 One follow-up question. Can I exchange the wheels with the 16in wheels on my 05 GS300? I know it won't handle as well, but she is much more interested in comfort. The harsher ride doesn't bother me. Quote Link to comment Share on other sites More sharing options...
Samsonn25 Posted June 10, 2019 Share Posted June 10, 2019 Make sure the struts and strut mounts are in good shape, they usually wear out at 50-60k Quote Link to comment Share on other sites More sharing options...
