Yeah those are small suv tires (blazer, explorer).

Run a 245-35-20 or 255-35-20 either will work and look good.

well the plan was to run these tires on the back but they rub hard but my buddy has a set of really skinny tires that are p?/30r20 or p?/35r20. but i wanted a set of 18/20 combo but got these 20s for a killer price so i figure if i can run these tires on the back it would like like a meatier tire in the back but oh well. so the ones my buddy has should fit nicely then?

The 35 series will. 30 series will be too small unless your bagged or juiced.
Where do they rub on the back on the frame rail?
If you want the staggered size look, do the 245-35-20 on front and 255-40-20 back.

i dont know how familiar you are with gbodys but. they rub right on the frame in the back of the tire like not on the inside of the tire but the back of the car. and on the front they rub on the fender infront of the rim.

Its all good, i have a 86 monte. The 245 is the section width (width in mm of the tire)
The 35 is the aspect ratio (tire height not in inches or overall diameter)
The 20 as u probably know is just the rim size.

The overall diameter of the tires that are on the rims the 275-45-20 is 29.8" in height.
The overall diameter of the front tires i suggested (245-35-20) is 26.77" in height. BIG DIFFERENCE Over an inch and a half top bottom left and right.
The overall diameter of the rear tires i suggested (255-40-20) is 28"

They should give you ample room to turn and still clear your frame rail.

good info. well good to know about the 35 series tires too cuz my buddy bloew a tire yesterday so bought 4 of a buddy and it turned out to be the rim not sealing so hes gonna put the old tire back on after he gets the rim fixed and i got 4 pretty much brand new tires for 100 or 200 either way good deal.whats the widest tire i can fit on a gbody with out running into problems? keep in mind the rim it self is pretty close to the frame on the inside too i have a 1/4 inch spacer on there now with out it the rim would rub frame.
