Hey all,

 

So I've been reading these forums since I bought my truck last July and have yet to been unable to find an answer to any of my questions. Whether it be lift size/install or common problems or mods or anything under the sun...until recently haha.

 

So I'm currently in the market to buy new rims and tires. I've tried searching for someone who has a 20x9 rim with +1mm offset on a leveled gmt900 but have been unsuccessful. I'm worried that this rim is going to stick out to far with just the level and running cooper zeon ltz's (305/50/20). Also, would a 275/60/20 be a better fit??

 

I know the stock offset is +31 but the rim is more narrow, so I dont know how these will compare. I'm also wanting to make sure that this rim will be okay to run if (more likely when) I go from the RC 2" to the BDS 6".

 

The rims also come in a +14...

 

Any help would be much appreciated!

In theory the 305 on the +14 offset will stick out the same as the 275 on a +1. 275/60 on a +1 will defo rub, I have 275/60 on 20x9 +14, I wish I had around zero tho, that extra half inch would be perfect just at or maybe a touch outside the fender.

275/60/20 with a 14mm offset has no rubbing? Looks like i found my answer, thanks!

 

Well you need to trim the very bottom of the front fender liner at the back for 275 60 20 +14 but nothing major

i am going to run a 20x9 with 0 offset and 305/50r20. Ive seen a few post on here with that setup and i like it! the 275/60 are taller and much skinner but i know u will rub bad with 0 offset. The 305/50 shorter but will look taller IMO and meaner with the being so much wider

I need help! What offset do I run to not rub and to have just about an inch and a half sticking out of the fender?

 

ANYBODY?

Not possible friend. You'll want a -12 offset or 4.5" backspacing to stick out that far and you'll need a sawzall to alleviate the massive rubbing you'll have. Might be better off with 0 offset / 5" bs, but still gonna need that sawzall. You might consider a 305/50/20.

Ok understand all I'm getting -12mm and 4.5 BS from the shop I'm working with too.

When will this rubbing occur? Only at full lock or hard turns? Or will it be bad just whenever I turn. Also the sawzall you mention is for the inner wheel lining plastic correct? I'm ok with that as long as the damn rims and tires don't stick out with the deep dish look. can you confirm that a -12mm and a 4.5 BS will look fairly normal and not create the deep dish rim look, that is simply the only answers I'm looking for before I pull the trigger. Thank you!

Depends on the wheel design. Sounds like you need to go look at some wheels since you have really specific wants. The sawzall will be for the metal behind the plastic liner.

      ‘25 Silverado purchase- back to dealership for bumper/radio issue

      The no sound problem is the audio amplifier. The audio amp has a heatsoak issue in some circuitry which causes it to miss the wakeup handhake. If it doesn't respond within a certain time parameter, then you get no sound. I brought it in and had the software update, but after further testing the tech made the call for a new audio amplifer. The software update I belive gives more time for the amp to respond, but if the amp is defective then you can still get no audio at times. After the update it went 12 days before no sound. After doing some research, apparently the fix is a new (updated) audio amplifer, the circuitry internally has been improved to better deal with heat. I had to wait 2 1/2 weeks because at the time, it was on backorder with no eta. Well the amp came in earlier this week. I had the amp and programming work done today. After picking it up I stopped at a few places, and whenever I started my truck, the audio was on instantly, so whatever they did it appears to work because it's never had sound that quickly......Hope this helps

      Make sure the latch mechanism is properly greased. Look at the catch for fresh marks/scratches. And see if it has moved a little, too.

      Thoughts on these wheels?

      By PBNB · Posted

      I have the 18" black mutilspoke wheels that came with my truck. I like them as they are very subdued and look good with the 295/70's    I am sure that the next set of wheels I get will be some after market all black wheels. Or maybe some AT4X wheels.

      OCI, not when but why?

      Interesting question which you partly answered in the word 'potentially'. I think that is going to be a 'point of reference' inquiry. What are the touchstones?    This will sound petty but it is the main source of end fighting in threads on this topic. Define a motors "Life". Think about the various arguments that have been entertained on these pages in that very argument.    I can only speak from my viewpoint. Engine "Life" in my world is defined by power cylinder integrity. For the majority of engines it is the bore/ring interface that quits first. Loss of seal. Oil consumption and loss of power. Most Pro motor builders would agree and there is a good deal of information on using "Leak Down" as a primary indicator of bore integrity. At home a compression test is more the thing. If we can agree on that then I think CC Jensen has done its homework and I'd find it valid.    Now by my own definition, Dizzy, wife's Ecotec 2.4 I-4 has been dead since about 80K miles. And yet we have logged over 200K miles more on it. "Life" and "Usefulness" are therefore independent.      I know a mature fella right now who has just hit 300K on a Mitsubishi 3A92 NA MPFI motor and has done compression test every 100K. It was 205 psi after break in and is now about 195 and still even. He uses shelf oil but good filters and adheres to a 3K mile OCI. He even do UOA's on each of them for the first 50K.      I also know a fleet mechanic with that same motor that gets 300 to 500 K out of them but the are oil using, wristpin sloppy, skirt slapping motors. He ran one with a piston pin so loose the piston was bouncing off the cylinder head for about 20K miles before he called TOD. Both of them claim success.

      Shouldn't the fault be saved and able to be pulled with a reader? Otherwise, maybe start taking pictures of it which will have a date and time stamp, so you can build your case.
