does anyone installed 245 40 19 tires on there GS350 AWD F sport wheels? will it work fine? I just purchase the car a week ago, and notice the tires are Turanza which not a great tires for winter, wanna see more options of tires instead 235 40 19.

 

Absolutely..

Just go to trdparts.co.jp..look under Lexus GS, Parts list..

The recommended tire size is 245/40/19 for the 19X8 TRD Forged wheels, 45mm offset wheel.

Our OEM wheel is 19X8, 45mm offset as well. So, it's the exact same specs..

I can't see an issue if you go with what's recommended by TRD..

 

Same tire size on my fronts. No issues.

 

thats great gonna get me some new tires, thanks!

 

YEP! I have the 245/40R19 Michelins on my F-Sport and Its perfect! I have told others to do the same. The turanzas are JUNK. I tossed them in 2 weeks after buying the car last year. I have the Michelin Primacy MXM4 tires 94V and I love it.

 

Does anyone know if these fit on a stock RWD F-Sport with the staggered set-up? That is, can I use the stock wheels that are slightly wider in the rear and still put 245/40/19 all around?

 

Yes you can no problem at all, I ran 19x10.5 and put 235 tires on it.

 

I'd advise against putting the same tire size front and rear on the staggered wheels. I did put the Michelin SS on with a 245/40 in front and a 275/35 in the rear. Works great!

 

It also doesnt hurt too have even track
