hi everyone- first post here. i read through a lot of posts to get very good info, but there's one thing that i just can't comprehend...wheel offset and backspacing etc. it's like i'm reading chinese!!

anyways- i have no lift: i'm looking to get 20x9 rims.

i'm looking at 285/50/20 or 305/50/20 nitto terra grapplers, but that's not 100%. or do i need to look at a different size tire? i don't want them to be super super thin...

what backspacing or offset do i need? and which tire size is going to look better? which one would stick out further: 285 or 305? i'd like for them to stick out just a tad.

i don't know what any of it means...

thankssss

This may help answer your questions.

My Off Road package Titan has 285/70/17
I've got 275/50/20 as well.

Side by side difference isn't bad and the 275's are lighter so I get better gas mileage.

But I bought a set of 305/50/20 and they are fairly equal-about an 1.85 difference in sidewall height.

I have 285/50 20's MB bruzers. they weigh 10lbs. more each than my stock 18's with the wrangler tires on. The offset is where the wheel bolts up to your axle hub so the more tucked in you want your wheels to be the higher offset you want... the lower offset puts the wheels out towards the fenders. I went out and look at my old wheels just now and the offset is not stamped on them but I am guessing 20 to 30mm? My buddie in nissan parts didn't know it either. You can look at my trucks album and see the bruzers on my truck are 18mm offset.

thanks guys! i would want my tires to stick out an inch or two farther than yours...

what about the backspacing?

if i were to choose a 20x9" wheel, what is the widest tire i could get without having to do any trimming or anything? could i fit a 305/50/20? or would 285/50/20 be better?

305 is perfect imo... I only went with the 20 8.5 285 because the tires and wheels only cost me $800 from a friend. My buddys 06 titan rides on 24 with 305 with no problems. You could even go 22's and lowered and be clear.

The 305/50R20 is only 32" diameter and should clear on a 20x9" rim with 5.71" backspacing, but the outside of the rim will only stick out 3/4" more than stock rims.

A 9" width rim with 4.5" backspacing sticks out 2" more than stock, but can rub at the pinch weld when turning when running 33's on a leveled Titan. So a 32 might clear on this rim if, leveled. For non leveled, a 9" rim with 5" to 5 1/4" would have a better chance of clearing, (with the 32), but wouldn't stick out as much.
