I need to swap my rims out. The 15"s are just a lil too tight on clearances with the inside of the rim. I'm movin on up to 16"s. Now...

I'm buying rims to last the life of the truck. 16x8 or 16x10? Tires will stay 33x12.5. I'm a firm believer in the 8" wide rim for 12.5" tires but have been stalling the order due to reconsideration of the 10" wide rim. Usually when I get these things in my head, there's something to them.

Anyone have any real world advice and not what your gut or voices in your head tell you?

 

10 nuff said

 

My question would be why do you think the 15 is to tight on clearance? If it's not hitting, it's not too tight. You should see the clearance on some of the race cars we build, the outer lip of the caliper has to be ground down to clear and if it's within .060, I call it good. Never had one fail yet.

Now for the size, I would stick with a 10 simply for tire wear factors. It's not too wide by any means and an 8 inch rim can be used as well but the fact remains it wasn't designed for it. The only reason you can get away with it on a larger tire is the amount of sidewall it has to allow the added bulge of a 4 inch difference.

 

I've got scrapeage issues on the insides on my front rims. I just bought these rims/tires to get me by. The time has come to get what I want now.

I got some picture taking to do tomorrow and I'll snap on or two of the carnage. It's not horrible but when the steering is at full lock there's something digging into the rim and has scored a ring around the inside of the rim.

Rears are fine. I've been kinda wanting to go to a 10" wide rim anyhow.

 

the brand and offset with matter in how the inner angle is on the rim 1 company can be different then another with clearness thats why with the bigger rotors edge plus 15" wont fit but alcoa's will. is the angle on the inside of the rim.. just something to chew over

 

So if I went with a 10" rim, what'd be the ideal backspacing considering I don't wanna go more than 1-2 inches outside the flares?

 

well the 15x10 are like somewhere around 3.83 i think i cant remeber its on summit. and you have seen bills truck thats what he had

 

ideal BS I'm not sure, but since the RCD calls for 4in BS and the stock alcoas are 4.5 in BS (which you don't have the alcoas), I'm shooting for 3.75BS. Right now I'm entertaining 15x8 mojave teflons. My only problem is I want something "strong" like the alcoas (they're forged aluminum, thus strong and light). Finding forged aluminum wheels = $$$$$ so far.

 

I have 3.75 with 15x10 and at full lock I have no rubbing at all.

 

^^^I have the RCD to worry about as well....

 

if you get Mickey Thompson, your size should be 15x10 with 3 5/8 backspacing.....that is what all the guys running Mickey Thompson's have for backspacing.......are you talking tight around the brakes or other parts? if it is around suspension parts, then your wheel backspacing now is too big......stay with a 15" wheel because larger tires are cheaper for them.......when you get into the 16" wheel you have to get metric tire sizes.....so you would be running a 305/70/16 for a 33" tire...

15x10 w/ 3 5/8 backspacing is what i say

 

RCD says that the wheel MUST NOT exceed 4" on backspacing....so if you went with the 15x10 w/ a 3 5/8 backspacing then you would be good....

you are the 1st person i have heard to have problems with the RCD and 15" wheels....i would bet it is because the Level II Alcoa's have a 4.5" backspacing....that .5" makes a big difference...

 

his arent alcoas.
i was wonderin if you ever figured this issue out. i would be interested in seein pics of the scrapage, to see exactly what you are rubbin on. also findin out exactly what BS those rims you are runnin have.

those things would help pick out a better fitment. the rest is all speculation.

 

awwww i thought he was on stock wheels.....

i would still say you have too much backspacing in those wheels...

lets just say that it isnt wheel diameter causing scrapeage

 

get some 20's j/k

but 16's would be nice

 

oh, but it could.
if he wants to keep the tires under the truck, dependin on where the scrapage is occuring, a 16" wheel with similar BS to what hes got now might work out.
for instance, if the 15" rim is rubbin on the upper balljoint due to the combination of the taller spindle and current BS then a 16" rim w/the same BS might clear the BJ.

like i said, its all speculation w/o specifc knowledge of his situation

 

if you stick with a 33, get an 8" wheel. unless you want width..

good backspacing to stick around is 3.5-3.75.

 

Cleaned my wheels last night =] Pretty proud of my lazy self...Then had to drive through nasty puddle to get in my driveway

It was getting close to sundown by the time gumby reminded me. My fiance has the digicam so the cell phone and garrity lifelite had to do, lol.

 

Check out my sweet calipers =] I'm so lazy. I have new calipers and pads just sitting too.

 

looks like scorin is on the lip, not in the barrel of the rim, correct? all the clearences inside the barrel of the rim look ok from what i can see there

if so id be lookin at the the upper balljoint to see whats goin on up top...

 

the oval is showing the scoring, it's about an 1/8" deep now. The circle is showing what is doing it. With the wheel perfectly straight, I could maybe stick two or three sheets of paper between that and the rim.

 

ok, it is in the barrel then. hard to tell cause some wheels have a divet there on the inside of the barrel relating to contours inside the rim that deal with tire mounting.

16's or lower BS will cure that. your choice dependin on what look you are after for wheels and tires.

 

I'd much rather stay with a 15" cuz like Maurice said, the tires are hella cheaper than 16"s.

 

well RCD calls out a max BS of 4" like maurice stated above, so id follow those guidelines for a 15" rim and youll be fine

jus gotta decide on width and how far you want em hangin out of the fenders now

 

let me go get a picture.. i think it will fix your issues...

going to the garage now...
