I am currently running 285/50/20’s. What will going to 275/65/20 do? Will it be much different in size, i.e. if I have no rubbing issues now will I with these?

 

ya you'll rub your going from a 31" tire to a 34" tire

I'm just joking bro, here's a metric converter to actual height and width http://www.4x4sites.com/techreports/...ator/index.asp

 

Thanks for making me sweat man!

I used this calculator and the specs don't seem that far off.

I run the 285/50 and its a great size IMO, they're wider and just a hair shorter than the 275/55s and always cheaper. good luck

 

Slap 'em on and see if you do or don't. If yes then just trim the plastic skirt in the wheel well. I stuffed 35"x13.5" Mickey T's into my avalanche (I have a 6" lift though so height may be an issue for you)

 

Are you sure 275/65 is the correct size, or could that be a typo and you meant 275/55?

If it is a 65-series sidewall, you will undoubtedly have fitment issues. Most folks I know have gone with at least a 2" lift to run 33" tires. Since these are a bit over 34", you'd need to go up, I'm guessing by at least 4".

If it's the 55...no sweat. It's actually the same spec as "stock" and just a wee bit taller than your 285/50's.

 

Yeah, I gave up on the tires for now. Thanks for all the help guys!
