I have a 2011 Chevy Silverado 1500. Recently put a rough country 3"lift/leveling kit on it. It is similar to this 2.5" on their website. For whatever reason I cannot find mine I bought. http://www.roughcountry.com/suspension/4wd-chevy/1500-leveling-lift-kit_1305.php

 

Currently running 275/60/20 with no issues. They are on a 20x8.5 rim.

 

I want to buy the 35x12.5x20 TOYO Open Country AT2 tires, but am afraid of possible rubbing (during turning). I've heard it all from yes it will to no it won't. That is why I am reaching out to those who would probably know more than anyone else.

 

I've ran all the tire-calculations. With the current 275's I have I am not worried about the height of the tires. I got plenty of room. With the 35x12.5x20 they are 15% wider than what I currently run.

 

Will there need to be cutting involved or will they work just fine with the lift kit I have? Or is there something else or different tire you recommend?

 

Please share any ideas and opinions. I need help before I spend a lot of money on these tires. I would love to get a tire on the rim somewhere so I can try it out before purchasing, but most places don't even carry those sizes stock and usually have to special order them in. Attached is a few pictures of my truck with the lift.

I am sorry looking for 35's. It is changed in my original post.

 

Please explain why they will not fit. Like I said I've heard 50/50 but no one has explained in detail why it will or will not. Thanks for the post. I've even used tire calculators and really only big difference is width (15% more than what I got now). Obbiously these are 12.5 wide. The 275/60 are like 11.6 wide or so. I know that difference van mean not much or a lot. Just trying to get some details.

 

Thanks.

You need to recalculate. A 275/60/20 is only a 32.99 x 10.83. Take into account tire variations from company to company and we'll just call them a 33x11, which would never come close to that size mounted. You want an additional 2.5" in width and 2" in diameter. That's a huge difference. You will have to cut metal out of your fenders and they'll still rub the sway bar. The rubbing of the sway bar will be due to the width of the tire and the conservative offset of the factory wheels. The only way around that is new wheels or wheel spacers which will worsen the rubbing in the fenders. Can you run the tires? Yes. Can you run the, without further modification and rubbing? ABSOLUTELY NOT. 100% guarantee.

It will rub for sure. Whoever told you it won't is a complete idiot.

 

I have 6" lift on 2500hd, lowered to 4" for perfect angles and it rubs with 35's. Even set @ 6" it still rubs. Even with custom bumper and some other fender mods.

Yeah I have 35's with a -12mm backspace on a 4-6" lift (cant really figure it out, RCX is retarded) and I had to trim valence, and bumper, as well as fender liner so they wouldn't rub. Fixed that with a body lift. I know yall are talking about the NNBS, but they are more square than my truck so it will definently rub

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
