20 in rim questions on tires

[project-c2]

What size rim and offset is everybody running with no rubbing issues. Should I just keep the 255 tire width or go wider? :dontknow: Trucks are new to me

Hey Im goin to order my wheels and just wanting to know if 255/35/20 would be the right tire size for 20x9'' wheels? I also will be dropn my X with the DJM 3/3 kit i just got so that will be my setup and i think 255/35/20 will work with the least amount of rubn...

What you all think... I think thats the tire size Jonathan told me to run...

just so u know 255 isnt the width of the tire 45 is

I thought it was 255=width and 35=height

are you sure, 255 is the width, 45 is the profile. maybe im wrong:dontknow:




anyhow i have 275 45 20s on and i rub, but you can get 275 35 or 40 and you wont rub

i am running 20x8.5 front +20 offset 255/35/20, 20x10 rear +25 offset 285/30/20. no rubbing and the wheels are flush with the fender.
and to clear up the confusion 255 = width in mm, 35 = aspect ratio(percentage of the width)which determines the height.

just so YOU know, your wrong. 255 is the width, 45 is the profile height. :eviltongue:

So the other person was saying the tire is 45mm wide and 255mm tall?:dontknow: Anyways. I think the correct terms are 255 is the section width of the tread surface in mm and 45 is the aspect ratio (ie:45% of 255mm) So 255x .45=114.75mm tall sidewall.:top: So I would be looking at a 20x 8.5 in rim front and rear with a 255/45-20 tire if I don't want to stagger.

a 255/45/20 is considerabllly taller than the stock tire height. 255/35/20 is the exact same.

35 series, damn, the side wall must be pretty skinny. Oh well, I'll see what shops have options for my truck later on. Thanks for the help.:top:

just so YOU BOTH know, i didnt KNOW that. but now i do, so thank you

No prob. :top:

 

[flyinbryan]

SOOOORRRRYYY i just always knew it as the lower the # ie. 55,45,30 etc. the wider the tire.


my bad...

 

[blackx-runner]

the lower the number the shorter the sidewall. Like they said that number has nothing to do with the width of the tire. It is the ratio of the sidewall height to the width of the tire.

 

[nick81olson]

So most people on here with aftermarket 20s run a 275/35/20 OR a 255/35/20... So what if you ran a 265/35/20 and be right in the middle of the two?

265 would fit nicely on a 9.5" wide rim. I think Jonathan said once that a 8.5" wide rim is optimal for our trucks which would need a 255.:dontknow:
