2010 RS Rims/Tires

[Skurpio]

Hi...stupid newb questions here...

Little back ground...
JUST picked up a 2010 2LT w/RS like 3 days ago.
Has x4 brand new tires. They put 4 new tires on the vehicle. (Of course they are the cheapest Ironman things you can get.) All the rims look like stock so I do not believe they replaced any of them.
245/45ZR20 103W on Front.
245/45ZR20 103W on Back.

Yes....all same 4 tires in a square setup.

I did some reading through posts and found the stock list for the 2010. And I have come to learn that Stock has offset tires/rims (245 F vs 275 R).
And you can run a square setup with 245s all around because the 245s will fit the rear too. BUT the 275s will NOT fit the front rims.
1 - Is that correct?

2 - If that is correct - then is there a way I can measure the size of my RIMS without disassembling one of the 'rear' tires.

Thank you.

You may have four front wheels on the car. Measure the inside of the tire barrels to see if they are the same width. Stock wheels are 20x8 and 20x9. You can also look on the back of the wheel and see if you see an 8j or a 9j. 8j would be an 8 inch wide wheel...

^^^ This. Or another way to tell is the front 245's will look normal on the sidewall on an 8 inch wheel, and the rear 245's if they are on the stock 9 inch wheel will look a bit "stretched", and won't look like the fronts. If the rear wheels are in fact 8 inch like the front, they will both look exactly the same, front to back...

All the info is stamped on the inside of each rim, Just pull wheel off and see size and offset
