With the correct B/S and a fender lip roll you can easily fit a 255/60/15

and most likely a 275/60/15.

You would have to double check on the 275's with a Monte owner here.

Okay this is how much space I have

Okay but I’m tying to use the same tires I have if I get 15x8 wouldn’t I have to buy new tires for the rear? And if I do 15x7 I can use the same tires I have right?

Yes but..............

Always look to the future!!!

As Wraith stated that is strictly a front runner rim requiring a skinny tire, you would probably want to look for a 15 x 7 with around 3.75"-4.00" of backspace with a 5 x 4.75 bolt circle.

have another question for the back wheels . If I order the 15x8 what backspacing do I need? 4.5 or 5.5?
And would it require a skinnier lug nut

4.5" backspacing

I wouldn't even try a 4" b/s; 3.75 is the way to go in a 15" rim. I had the wheels off the 67 (<---- see avatar) which were 15x7 front and 15x8 rear with 4" b/s, with 1/4" spacers (makes it 3.75), and the 275/60s rubbed pretty bad in the rear.

Some wheel companies allow for custom ordered backspacing. I know American Racing does on their Torque Thrusts. You generally have to wait longer on them. AR waits until they get several custom orders before they set up shop and make those. For example, on my 68 Cougar I custom ordered 17X7 with 4.5" backspace. Standard is 4.25" I waited 10 weeks for them. But oftentimes, that's what it takes to get the right stuff to fit.

On the G-Body front, my non-winter wheels on the rear are 15X10 with 4.75" backspace and a 275/60/15 tire. Thanks to the great quality control on these cars from the factory, the driver side fits fine and I get plenty of clearance all around after I trimmed and rolled the fender lip. I also trimmed and rolled the fender lip on the passenger side. But the 4.75" was too much and the inner sidewall rubbed on the frame rail. It was really only the raised white letters that I always turn inside anyway. But I bit the bullet and notched and replated just that one side.
