Wheel Spacers and 0 Offset

I'm narrowing down my wheel choices and the wheel I like most has a 0 offset. I'm currently running stock sport wheels with 1.25" Spidertrax spacers. Ideally, the wheel I really want would have around a -12 offset.

All of that being said, how bad is it to run a wheel with 0 offset with my spacers? I'm very attached to a wheel I found, but I'm struggling to change my opinion on the offset.

Also, if I run the wheel without the spacer, can I fit 285/70R17 major trimming or a CMC? From everything I've read you can run 285/70R17 with only removing mud flaps, but I've only been considering that for a wheel with a -12 offset.

I should also mention that I'm running a Bilstein 887 coil set-up, to give myself 2.75-3" of lift.

Any help on this would be great, because I've been looking at wheels for 3 months and I can't sleep at night

 

Any help?

 

What's the back spacing of the new wheels? That's going to affect fitment and rubbing vs the offset.

 

Read through this thread as there is great info here

5" I wish I would have read that before now

This is what I bought

I'm also looking for big help on tires. Most likely, I'll be buying BFG's KO2s

 

4.5" of back spacing is the minimum required to fit 285's. so the less back spacing makes it easier to fit wider tires. for example 4" is less back spacing than 4.5". So if your new rims are 5" of bs, and you run your 1.25 spacers, that makes your total bs 3.75" which is a good amount of clearance needed to fit the 285's and them not rub suspension parts like upper control arms or the spindles. The stance will look aggressive and you'll only have to deal with light trimming and maybe a cab mount chop.

I'm running the trd tx rims with have 4.5" of bs. I have 285's, did a cmc and slightly trimmed plastic, and had no rub offroad with my swaybar off. I recently added 1.5" spacers which brought my total back spacing to 3". I am now dealing with rubbing of the plastic of the front bumper (which i literally just got done trimming). I've not yet gone offroad of flexed my from suspension to see where I'm really rubbing as it was only rubbing in reverse when turning.

 

I looked at running 275's, but they aren't recommended online for a wheel over 8.5". It looks like I've left myself no option but to do the CMC and trim any rubbing.

This is all really disappointing, especially since every other wheel I considered was 4.5" bs.

So I guess I'm locked into running 285's and spacers as well?

 

I do agree that the rims you are set on look badass, but it may not be a bad idea to have a set of other rims to fall back to if you don't really want to run spacers or have to trim alot.

Also, do you offroad? That's where rubbing really shows itself, plus the potential to screw up rims. But if you just stay on the street, you can get away with those rims and spacers with some trimming and maybe a cab mount chop, that part really depends on your alignment; more specifically caster.

 

I've never gone offroad before. I'll maintain my stock rims, but I probably won't buy new tires for those.

Should I get the CMC done before or after the wheel/lift install?

 

I'd say after, you may not need it, but the way to tell is to install the lift and tires and see.

 

According to his first post, the wheel he's looking at is a 0 offset. Assuming it's a 17x8 wheel, his backspacing will be 4.5 as is. With the addition of the spacer, that would put his backspacing at 5.75 which would give you him an offset of roughly +31-32ish. Holy Poke Batman.

Offset is the key as it's calculated using backspacing and width of wheel. 0 offset is the target number. 4.5 backspacing on a 16x9 wheel = -12.7 offset which means it wouldn't clear the control arm. 4.0 backspacing on a 16x7 = 0 offset which would work...The more positive the offset, the more clearance from the UCA you will have; HOWEVER, this doesn't change the puny size of the taco wheel well. You will most likely still need slight trimming and CMC if you want no rubbing, especially if you off road.

I'm running 16x8 wheels with 4.5 BS/0 offset and 285/75/16's. I rub the cab mount at full lock reverse and still need to trim the liners a bit as I rub while wheeling. Nothing major though.

 

I don't know. To be honest, I'm actually not very good at this job

Looks like i have more learning to do.

 

Hey man, no worries. You were trying to help and you were mostly right, just missing some stuff. Wasn't trying to call you out, just adding on to what you said.

It wouldn't be bad per se, your wheels would just stick out pretty far. At a 0 offset with my setup (which is similar to what your looking to do except in a 16) my wheels are almost flush with the widest part of my fender, but still pokes out a little. You would be adding another 1.25'' to that. If that's the look you're going for, go for it.

You will NEED the spacer if you get a wheel with a -12 offset. You will need to trim and CMC. You can run a 0 offset wheel without the spacer. You will need to trim and CMC. You can run the rim with the spacer. You will need to trim and CMC. See where I'm going with this? the backspacing/offset will get you the clearance you need to not rub the UCA, the size of the wheel well doesn't change.

All cars/trucks are slightly different. I've also read that some people get away with just removing the mudflaps running 285's on a 2.5'' lift and 0 offset, but I think that's more the exception than the rule (and probably poor alignment). With a 0 offset, the rubbing isn't as bad as you think. You'll only rub the cab mount when reversing and the steering wheel turned almost all the way and the rubbing on the front is a quick fix.

 

The wheels I bought are 17" x 9" wide. It sounds like I should buy the 285 BFG's, throw everything together and see what happens.

I just don't want to be stuck with a truck that I can't drive or that I am going to risk causing damage to. This is my daily driver for the foreseeable future.

Anyone else want to weigh in before I pull the trigger on tires? Can I run 275's even though the BFG specs don't recommend it for a 9" wide wheel? Would it even make a difference if I did use 275s?

 

17x9, but 0 offset right? If so you'll be fine. You're not going to damage anything except maybe some inner plastic in the wheel well.

 

How'd it go. I'm running 18"x9s and 0 offset on 285/65 and not rubbing. You should be more than fine.

 

I'm all good with the 285 BFG's. No rubbing at all after alignment.
