I was wondering if anyone knew what is the biggest tire and rim combination that can fit on the rear of a 1980 Trans Am without doing any modifications to the body.

The largest that I have seen on there is a 295 series tire.  That is about the widest you can go.

is that the widest you can get to tuck inside the wheelwells? I don't want them to stick out, I want to lower the car and have the wheels tucked inside the wheels wells.

No, the 295's will stick out if you plan on lowering the car.  They are tight with a 295, and if you lower the car, then I think they will not make it.  Here is a couple of photos of the last car I did that had 295's on the rear.....

Depends on the offset of the wheels.. Have 295s on the 72 Formula, and have 285 65 15s on the 79 Formula. But the 79 has had the fender lips rolled.

If you dont want to roll he lip, and you dont want the rear lifted, then a 255 or a 265 is about the biggest that will fit on a stock rim and not rub anything with heavy people in the back seat. My 79 10th Anniversary TA had 255 60 15 BFGs all the way around it on the stock turbo rims.

With the right offset a 275 will fit on a low car, but the wrong offset even a 245 will rub.
Performance and general repair tech. Traditional Pontiac V8 is my specialty, as well as automatic transmission repair/diagonossis. 2nd gen speciality, and with the addition of the 98 Formula 4th gen LS1 I am getting to know them real well. Holley and Qjet advice as well.

Chalk mark restoration and date codes arent my thing. W.O.T. is my thing..

Is it strange to have 9 firebirds?
