Cool 245/75R16 to 275/60R20

I have a 99 ram 1500 4x2 stock height and am trying to figure out if I can run 275/60R20’s on my truck without modifying anything. Thanks

Thats a 33" tire and almost 3" taller than your current size. I believe it will fit but your speedo will be off by 5 mph at 60. Moved this to the 2nd gen Ram section so others will add their experience.

Yeah, speedometer will be off by 8.2%..... The shorter sidewall will make it ride rougher. And watch backspacing on your rims, to keep the tire from rubbing on turns.

I put 285/70/17 on my 2wd 2500 and they fit just fine, but the speedo is off as stated before
