i have a line on 4 new 19x9 forged Fsport wheels et 40. I want to buy them but am concerned about fitment in the front. What size tires can I run on that setup? I am on the stock sport suspension now, but may go lower in the future with mild springs. The lowest would be H&R springs. I do not want to roll or pull fenders. Thanks everyone!

Are you looking to run a square tire setup? Do you want to rotate?

You could run a slightly stretched tire up front and a slightly wider tire in the rear to still give it a staggered feel possibly..

I run a 8.5" wide rim (19") et 40 with a 225/35/19 up front and I rub when I full lock reverse.. which I don't really care about I just manage accordingly

You could run a 235/35/19 on the 9" wide wheel - I ran this setup on all 4 corners lowered on f sport suspension on my 08 IS250

What were the specs on your previous 9 inch wide setup?

I will run whatever tires work, I dont want to increase the circumference a bunch for power reasons.

i can also run the staggered setup that is available, but it seems like the 9s all around would look better due to offsets and I think they are slightly more concave.

i am running 18x9 square ET40 with 255/35/18, 5mm spacer in front

Jwconeil

is the spacer for looks or clearance? Are you lowered?

strikeraj

for wheel spoke clearance from brake caliper

Jwconeil

im guessing you have aftermarket brakes. You should fit fine without spacers on stock brakes I would think.

I'm on stock is350 front brake. It is the wheel spoke design that cause the problem. I run stock 17 wheels in the winter without spacer.

I may use 255/35/19 rear or 275/35/19. Will the 275 fit? I'm considering 235/35/19 for the front. Is it safe to run 235 on a 9 and will it cause
premature failure?

id love to run 255 front and 275 rear if it would fit!

strikeraj

255/30/19 should fit in front, since it is similar to 255/35/18 in size
