2010 IS350 with 19" F-Sport wheels - Lowered on F-Sport shocks/springs. Lexus recommends the 225/35/19 for the front, I am running that now. Will there be any negative effects if I move to a 235/35/19 tire instead?

Thanks

It's tough to say, the car was built with the front and rear tires at different heights. If you move to 235/35R19 it closes the gap in height from front to back, so now the front tires will be spinning less times per mile and perhaps could trigger the ABS warning light. The IS-F runs taller tires than the IS350, so as far as rubbing issues with the wider taller tire in the front of the IS350, I couldn't say either way? Since the car is so new and probably still under factory warranty I would just err on the side of caution and just stay with the Lexus recommended sizes.

I'm runing 225-40-19 on the front and 255-35-19 on the rear, with eibach prokit dropped with 19x8" +30 offsets, i get rub on the front tires on dips and bumps on the fwy. it getrs annoying, and I already purchased 225-35's up front for the next pair.

I do not get the ABS light at all.

I'd think that 235 might be good if you want more grip up front to reduce understeer, but 225-35 shoudl suffice.

Youll be fine if you want to move to a 10mm wider tire. Its not drastic.
