Hello, I am an amateur at wheel specs and am looking to purchase some 18x8.5 +44 245/40/18 runs&tires combo. I have an is250 2009. I’ve tried looking on previous forums but I can not find an answer so I’m curious as to if this setup will work on my Lexus is250 for the front and back. All comments much appreciated

You’ll be fine with those wheels and tires. You may need a pair of 20-25mm spacers on the back to bring the wheels closer to the fenders.

 

Here's a very good resource to use that should help you: https://www.1010tires.com/Tools/Wheel-Offset-Calculator

Also, as far as fitment goes, it will also depend if or how lowered you are as well. Hope that helps.
