WIll these fit My ISF without rubbing?

Front: 20x9 245/35/20 +38 Offset Front
Rear: 20x10 275/30/20 +45 Offset Rear

Thank you.

 

No. You can't run a wheel wider than 6" or an offset higher than -14.

 

It will fit perfectly.

 

Agreed with shyguyF. That is a good fit. But just to note, all tires aren't created equal. Some tires are wider and taller than others even when both are labeled 275/30. A 275 in one brand can very drastically in dimensions compared to other brands. YMMV

 

So was Reaper21 kidding?

 

^haha....welcome to the "I have a question about fitment" club! Yes, that was sarcasm. There will be some odd responses. It just keeps things loose, I think. But CL does have a fitment calculator on it's tire/wheel page, so that can help you determine if your tire sizes are right for your car.

The sizing I think you have will fit fine. I've seen that combo run a few times with owners, and there is still some room between the bead of the tire and the inside fender lining.

 

Yes, and I sure hope you are too!

As others have said, both wheels & tires will fit perfectly.

 

You can go more aggressive offset in the front.
