Tire size for lowered trucks ???


Recommended Posts

Posted

hey everyone, i have a ? about choosing the correct tire size when upsizing to a set of 20" wheels on a 2wd reg cab that has been lowered 2" in both front and back. hind sight being 20/20 i ordered a set of 20" wheels and tires that i thought would fit but when installed the front tires rubbed and just did not look right. they are 275/55/r20 and the front look way to tall. i like the raked look i had with the drop what size tire should i have used in the front to keep the raked look? i had to put my stock spindles back on and have the front end realigned to use my new wheels and tires but when i wear them out i want to know what size i should check out. thanx in advance for any advise!!!

yea it did until recently, make sure that your bumpstops arecut in half. i also put helper bags on because i pull a little trailer the bags helped amazingly well.

check your bumpstops, drop shocks should also be a big help

i took the bump stops off and still bottomed out, even bought bell techs nitro drop shocks.

I've got a set of 22"s coming and I need to know what size tires I should go with. Right now I've got a stock 06 GMC 2wd Crew. I've considered doing 2" shackles with gas shocks/helper bags, because I need to tow a car hauler with around 3-4K. I'm thinking 265/35/22s!

I installed 2" drop shackles on my 07 classic and now i get a rubbing noise from under the bed, below the rear of the cab (reg cab). I hear it when I come to a stop or slow down quickly and sometimes when I go over bumps. I think it may be the rubber supports that hold the bed on the frame but Im not exactly sure. Im also not sure it is due to the 2" drop. I didn't install drop shocks. The truck has less than 4k miles on it. Anyone else have this problem? Any help is appreciated.

275-45-20 is the perfect size if you want a rake you can try 285-50-20 in the rear possibly..

this is what it looked liked with 2/4 drop on stock wheels and tires.

Holy Crap, big difference!!! It looks lower with the stockies. Waaaaaaaaaaay low!

i had problems with the leaf springs hitting the bed on my 92 truck using longer shackles to lower it, maybe check for that?

sounds like you may have the shackles to tight. what type are the shackles. some have the polyurethane bushing which if you do not lube when you installed could make a rubbing sound when the truck weight shifts forward or back. i would put a shot of wd40 on the leaf springs where ever they could rub and see if it went away. i also picked up a squeak in the rear of the cab below the drivers side and it ended up being rubber washers on the grounding strap between the frame and the cab. just a few things i've seen . lol, jd

My vote goes for 275/45r20's as well. I had 305's on my Avalanche and they rubbed a bit, 22's though.

 

 

same here, go with the 275/45R20.

I got a 2006 Chevy Silverado 2wd reg cab short bed I installed the BellTech 6400 Rear Lowering Shackles kit. when I idle at 30-35mph it make's sounds if I give it gas it stops. I know it's not exhaust but at the same time I installed power Stopped crossed drilled and slotted rotors but it don't sound like it's the rotor it sounds under the truck in the rear but can't figure out what

 

 

Also has anyone used BellTech Nitro Drop 2 Performance Shocks on a 03-06 Silverado?

I find them not to bad price on Ebay brand new I was wondering since It says front are 0-5" Drop and the rear is 2-4" drop dose these shocks drop your truck also or is it just saying you should only use them if you have drop the truck in those ranges? And how well are the shocks dose it ride better I know mine is rough ride compare to the newer silverado now days.

 

Also on my truck with 20" Helo wheels I'm running 275/50/R20 tires that are Front Sumitomo H/P and Rear is same tire size 275/50/R20 Goodyear Eagle GTII I don't run at all I had a stock factory height truck and only installed Belltech 6400 Rear Lowering Shackles kit you guys might be lower then I am.

    • 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.  
    • 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. 😉
    • 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.
