I'm about to purchase a GS430 that I have all the confidence in the world in except for the 62-75mph vibration. The Pirelli PZeros on it are needing replacement so the seller and I worked out a deal to have the tires replaced and road force balanced. If this corrects the vibration, I'm going home with this otherwise excellent GS. If not, I'm paying for 2 tires and half the balance and he has four new tires on his car that he is selling. So, wanting to keep the investment down but also wanting to get good tires that hopefully will be on MY new ride, which tires would be a good choice for a daily driver that will never see the track and will be driven "spirited" on occasion for fun? Right now my short list is the Falken FK-452 and the Sumitomo HTR ZIII. These are going on 17" OEM chrome 5 spokes. Please post your opinions on these tires or others suggestions based on experience

 

Toyo Proxis 4

The best tire I've had on my GS -- Quiet, never let go grip with great performance, no traumaling.

 

Thanks Scott. I'll check em out. Nobody else got any suggestions?

 

i'm surprised you need a road force balance for 17" rims... are you sure nothing else is wrong?

i'm having vibrations with my 20's that i think i need to get road force balance, i think i might set up a poll and see how many people needed to get their tires road force balanced for vibration issues..

 

how old a car, mileage?

Check lower control arms for wear, and ball joints as well. They degrade and can cause irregular tire wear at a minimum and may be causing vibration.

Just thinkin out loud-

D


Good luck

 

Thanks for the suggestions. I'm not sure really what to do. I love the vehicle after looking at it and everything else checks out but I don't want to start a love/hate relationship from day 1. The tires are just what we both thought of that could be tried to correct the issue. I've been reading alot of positive reviews on the Falkens on many different car forums.
BTW the car is a 02 GS430 w/77,000mi.
