morning fellas. what would be the widest tire i could go with keeping all 4 corners the same size on a 19x8.5 wheel with 45mm offset on a 2015 is350 f sport? not wanting to stagger the wheels if i can get all 4 the same size without looking goofy or not perform well.
thanks,

After upgrading to 19" wheels, I think 18" might be the perfect size. I also liked the staggered set up (thicker tires in the back), car felt more planted on the road but with the same tires all 4 corners, I can preserve tire life. I have 9" wide rims which sit pretty flush so 8.5 would be a bit more tucked but not bad. Won't look bad, just depends on the rims and tire size you are going for.

Also, for AWD system, you need to maintain the same diameter as the OEM wheels (or close to it) to prevent any AWD issues

 

my 18 inch oem wheels are full of rash from previous owner so they're gonna be my winter beaters. In the meantime Im thinking of running 19x8.5s in the front, 19x9.5 in the rear.

Not to sure which tires to run, but from scouting around the forums, i'm hoping the following will fit:

front: 235/35/19
rear: 275/35/19

Don't know if its the widest tho.

 

how would 235/35/19 look and perform on all 4 corners?
