Anyone know what the IS300 rim offset is? I tried doing a search on the forum and I couldn't find any answers. Thank you in advance.

stock 17x7 is about +50mm

Yep, they are 17x7 +50.

Christobol

no no no. They are +45

The most you'll want to go it 45 +- 5. Go any further and you'll start getting into trouble.

CAN SOMEBODY PLEASE HELP ME OUT???

18X7.5 WITH THE OFFSET OF +45, WILL THESE FIT IS300 FRONT AND BACK?????

Christobol

The rear will fit for sure. The front.... depends on the tires you go with. Worst case you'll have to do a little fender rolling (which isn't a large task). Chances are they will fit though. People usually don't run into problems until they get into 19" in the front. Some guys are running 19" 225/30/19 without a problem, but that is a VERY small tire.
