Largest tires that will fit a Trailblazer 16s

A buddy of mine put some larger tires on his wife's TB and it really filled in the wheel wells. Looks nice. I think they are the next larger size. He had to do a little grinding on the pivit joint above the inside of the tire. Only about a credit card width though. He was looking for some spacers to offset the factory wheels, but couldn't find any. I am thinking about doing the same thing when these tires wear out.

My 2004 has 17" wheels on it and trying to find tires are alot harder then 16". My buddy that just did the grinding traded in his 2002 with 16's for a 2004 with 17's. I had told him to swap the 17s for the 16s so he would have a better tire selection. But he didn't

i replaced my 245x70 with 255x65.. it looks a little better but this change was very minor.... tire is only 10mm wider and rolling diameter stayed the same.....

Search chevy wheel spacers on ebay, they have them for the trailblazer. 1.5 in spacers for 90.00 a pair

Not a good idea, makes the lugs weaker

doesn't make the lugs weaker. They are not any different than putting on offset wheels

RE Wheel spacers.

1. If they are just spacers then your lug nuts may not completely engage the studs.

:bs:

 

2. If the spacers are bolted on to the hub first and are aluminum then think about the fact that normal lug studs are grade 8 in steel and now you are using grade ? in aluminum. :D

 

3. No matter what you are now loading the ball joint and suspension in a manner they were not designed for. So will need to keep an eye on these parts over the long run. Yes different offset wheels do the same loading thing. :lol:

 

Just remember that you are modifying the vehicle and now YOU are responsible for result.

and your point is...... :banghead: You drive it off the lot and it is prettty much your problem. Yes some stuff will get covered by warranty. All I mostly was getting at with the spacers is that if you look at your suspension in the front you would see that larger tires would scrape on the upper section of the suspension. The spacers would bring the tire out so as to avoid the scraping which then allows bigger tires to be run. I do however think that a 265 or a 31in. will be as big as you can go without them rubbing when turning

245/75/16 bf goodrich AT no rubbing even under full compression. I've seen guys put 285/75/16.'s with a 2" lift. He had to trim a little in the wheel well though. If you dont want ot deal with the trimming 265/75/16 with a 2" lift will work just fine.

    • 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.
