Hey guys I need some quick advice. I have 33x12.50r17s nittos on stock 17s. Love the tires but I wish I would've gone a little taller. I've seen people running 35s with just a level but I decided to stick with the 33s. I now have a chance to trade my tires for a set of 315/70r17 duratracs. I understand they're about the same width and about an inch taller. Would you recommend this trade? Both almost brand new and even trade. Thanks!

Hello, I have done tire swap outs before. The main thing you need to make sure is, when the wheel is in full lock, will it hit anything. Bigger tires add issues, if they are not on the right set up.

The taller the tire that you install on your truck, the higher the gear ratio will become. Larger tires will also have a larger rotating mass due to the increase in weight. Both of these issues will result in a loss of low end torque. Your engine will have to strain harder to get the wheels rolling at the start. The stock drive-train and suspension components of most truck's are not built to withstand the extra stress that the heavier over-sized tires put on them. The added stress will accelerate the wear on these components and lead to failure much faster than a stock set-up.

Is there a real big difference between the two? I find the 315s to be a couple lbs lighter than the 33s according to manufacturer specs.

I'm guessing you'll have rubbing issues at full lock.

I don't mind rubbing. I don't do rock crawling or crazy off road. My main concern is gears/driveshaft/tranny holding up. Some people say I have to re-gear but I know guys running 35s on f-150s, rams and even Tacomas with no problems.

ur gonna run into a problem with the width of the taller tire. i rub with a 34/12/18 urs will be wider and taller. you will deffinetly need to get the top .5 spacer to make it a 2.5 level kit if you want to try it. stock wheels u will have a better chance than offset tho, if you dont mind a little work to make them fit you prob will be happy. I have been running 71lbs trail grapplers for 10k miles not there deffinetly alot heavier than my stocker size duratracs but i dont drive on the highway alot so it doesent bother me.

Have you measured them? My "33s" only measure 32 mounted

I'd keep your 33's. The only positive is a perceived improvement in looks. Your truck looks great the way it is now, imo, and larger diameter wheels will only detract from performance.

Yes, but you will soon be wanting 37's!

This is the best advise on this thread. Your truck looks GREAT like it is and I'd be very surprised if those 33s aren't already rubbing somewhere. If you want to run 35" tires properly, you need a 4-6 lift. 35s on a level look overstuffed.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.
