Default 1999 Ls400 tire help/suggestions

I got some new to me wheels and am having trouble finding tires that I like. The wheels are staggered 18x8(F), 18x9(R)
the tires I want to run are 225/40 front and 235/40 rear.the problem is that the tire sizes I want don't meet OEM load rating. I found 245/40 works for the rear but am stuck on the front. Now my question is will I be ok running g the set up I want? Is it safe enough to daily drive seeing as the load for the front would be 5 points lower and the rear 2 points lower. I've looked far and wide around Google for the past week and can't really find a straight answer.
Thanks!

Welcome to Club Lexus.

We see this discussion come across now-then, this has not been an issue posted on the forum that I've read. Most of us don't load our cars to reach that maximum spec in the first place. As you are aware stretching and using a lower load rating can be a risk. My interpretation is that there are rubbing issues that going with a 10mm wider F-R tire isn't going to clear the fenders?

I run a 235/45/18 on SC430 wheels in front with 15mm spacers and it clears fine. In winter I run 245/45/18 snow tires with no spacer since they're IS350 wheels and it barely clears the fender lip.

Yes, that's what I've been looking for, if anyone has had any troubles. But you're right, as far as I've seen, no one has. As for the rubbing, if any, I will have my fenders rolled to fit.
