Rim and Tire questions

I have a 2005 Moostang GT and have a few questions about tires and rims I'd like to ask.

I'm thinking about getting the American Racing Muscle Razor rims in 18x9 all the way around (only size they make besides 20x10 and I'm not getting 20's).





My question is, what is the offset? I'm guessing +40mm? What is the backspacing? I honestly have no clue on this...

What is the smallest tire I could go with and largest? I was thinking about 265/35/18 up front and 295/35/18 out back. Is that too big/small?

Thanks in advance for any input!

the razors don't have the right back space or offset they are 26mm and we need at least 34 to 45 depending on width of the wheels. the back space on razors are 6 in and most 9 in width wheels come with 6.29 or more. the size tires you mention are not tall enough, you need 255 45 18 , 285 40 18 like the shelby to keep tire height the same as stock. good luck and hope this helps you out.

I found them on Tire Rack in +40mm offset.

The link is really long so click here to get to the site.

I just need to know what backspacing I would need to make it fit on my car.

Thanks about the tire sizes, I'll have to go with the 255's up front then
