Plus sizing on 19s
So as I wait for my vehicle to come from japan. I'm looking at new wheels and tires as to pass bc inspection the tires from the celsior won't do since there not dot rated. My questions are as follows
My wheels are lexus f sport full face 19 inch rims staggered fit
19x8 in front 45mm
19x9 in back 60mm
Will 245 40 19 work in front
And 275 40 19 in rear
The reason I ask this size is because it's closest to factory and thats what I'm looking for without rubbing.
Also if I chose a different tire size does load index matter and speed rating
Original tires are 225 60 16 97v
I have upsize in the past on my wife's vehicle but only by one never by 3. So new at it. Thanks guys
Also I did use search feature on tire size but ls400 never came up only is350, gs and so on.
Also one last question does the celsior for those who have it , have day time running lights and are lights dot approved. Need that to pass inspection as well.

The wheels are VERY conservative, you'll need to make sure there's adequate clearance between the rear rim and the shock on the inside. Otherwise you should be OK provided the wheels clear your brakes. If they don't, you'll need a 10-15mm spacer in the front, which will mean the fenders will need a roll.
The tire sizes are incorrect, the rear you listed is too tall. You will need a 275/35-19 to maintain the correct diameter. The front is fine at 245/40-19. Load index and speed rating definitely do matter, you need a tire capable of supporting the weight of your vehicle. to simplify to an extreme, look for something with a comparable or better speed rating and load index. Plus or minus a couple points on load index is acceptable but you will have to check the load inflation tables to make sure you get the same loading capacity per tire. Tire manufacturers can help you with this if you get confused.
DO NOT RUN STOCK PSI ON LARGER TIRES. Generally you will under inflate and have problems. ALWAYS CONSULT LOAD INFLATION TABLES FOR PROPER PSI ON UPSIZED TIRES!

I'm debating on running 235/40r19 in front with 245/40r19 in the back but load is 96v in front rear is 98v or
What you said what's the proper size for what I'm looking for 245/40r19 in front and 275/35r19. Load exceeds 97v in those sizes
