Guys I recently bought a set of 20" wheels for my 04' gs300, they came with 255/35/20 kuhmo spt but i noticed after these times rode kinda harsh but handeling was good. Moreover, after these tires starting getting loud and shaking vibrating on me when i drove between 65-70 I gave up on them. A guy at discount tire recommened going with falken 542 255/35/20 as soon as I put these on I noticed a HUGE diffrence in the comfort of the ride and handeling. So my recommendation is if you drive on 20"s and need a good tire for cheap price go with the FALKENS ALL DAY!!
