Does anyone have 245/40/18 tires on their GS300? If so, what's the ride like on the parkway @ high speeds and when you're going over bumps or grooves?

Thanks alot...I'm going to order tires this week...Do u have a cold air intake or exhaust on your GS?

I have 245/45/18 on the front and rear, but was considering changing front to 245/40 because the car is kinda all over the place when i hit a bump. It just feels like i dont have total control, like i did with the factories. Does anyone have any suggestions? Can i put the 40's on the front, with the 45's on the back? Or do i need to go 245/40 on the front and 275/35 on rear?

Can anyone give me advice on using 245/45/18 tires on my GS. When I get to about 65 or 75mph my steering wheel shakes a little. I had the wheels harmonicly balanced @ American Tire Sat and I still get it. I didn't get it with my factories. I'm wondering if I should just go 245/40/18 in the front and leave the back the way it is. Can someone point me in the right direction?
