Default 275/60/20...

Will a set of 275/65/20 tires fit on rims that came with 275/60/20. I know it's a dumb question i just want to be sure and will they fit without rubbing on a 05 stock 2wd single cab?

You will be fine. They are they same width. The 65s are just a little taller

Default Tire Size

When you look at the tire size, the first number is the nominal width of the tire at the widest point. Nominal meaning under ideal circumstances (correct tire pressure, no excessive load, etc.) The second number is the hight of the tire as a percentage of it's nominal width. The "R" between the second and third number signifies a radial ply tire (as opposed to a bias ply tire.) The third number is obviously the diameter of the rim it was intended to fit on.

So with the stock tires (275/60R20)

275 = 275mm wide at widest point
60 = the height of the tire is 60% of it's width (165mm)

The ones your looking at are 275/65R20, so the only difference is the height is 65% of the width, which is 178.75mm. This means your tire diameter will be 13.75mm more, which is just over a half inch. Running them will not be an issue at all.

You're good.

It will actually be 27.5mm taller, a little bit bigger than an inch. The aspect ratio is each sidewall (so need to times by 2 to get the height)

275/65r20: 275*.65 = 178.75 * 2 = 357.5 + 508 (rim) = 865.5mm (34.07inches)
275/60r20: 275*.60 = 165 * 2 = 330 + 508 (rim) = 838mm (32.99inches)
