I had my truck put up on a hoist to see if my spare 33"-ish tire would fit; not even close. Would be up against my exhaust for sure.

I put a 35" underneath, i do have a custom exhaust and doesnt interfere with the tire. I did grind the excess material from the hitch receiver on the spare tire end (towards the front of the truck)

Related question.

I have 285/65/20s on my truck and have just replaced them after 50k. (BFG AT KO2s).

I told the tire tech to take the best old tire and mount it on an aftermarket 20" wheel I bought for the purpose and sling it under the truck.

The tire will fit but the problem is the hole for the hubcap is too big for the keeper on the winch. The cross piece on the end of the cable is too small for the hole.

 

Anyone aware of any adapters that can accommodate that problem?

I don't know of an adapter but you could make your own.

Take a flat piece of steel bracing, and drill a hole in the center. Using an angle grinder, cut a diagonal line through it to the center so you can slide the cable through. Slide it on the winch cable above the jig that holds the stock wheel and let it drop.

Push that whole kit and caboodle through the hole at the wheel and crank it tight. It's not gonna go anywhere due to the clamping force.

You could also drill holes in the "hook" that holds the spare on both sides and attach small pieces of flat of steel or aluminum brace.

I get what you're saying. Problem is I'm not confident that the steel would last long enough. I figure I need something at least a 1/4" thick and then coat it with truck bed liner or something to protect against rust and the corrosion that would be caused by steel against aluminum.

 

I was told there are adapters out there that would do what I need but I haven't found one yet.

I know its an old thread, but I made an adapter to hold a Method NV305 with the stock tire hoist. Should work for any aftermarket wheel with a 108mm hub bore. Part is made of aluminum so it wont rust or damage the wheel. If people a re interested I could make a batch.

2017 1500 Z71 CREW CAB. 

I JUST INSTALLED 285/75R17 (33.9") TIRE IN THE STOCK LOCATION ON THE STOCK 17" STEEL SPARE RIM TOW HITCH ALSO. IT FIT WITHOUT ANY ISSUES. 

I HAVE DO A CUSTOM EXHAUST AND ABOUT 2-3" ROOM FROM THE EXHAUST TO THE TIRE.  UNLESS IT IS TOUCHING THE TIRE, GAS TRUCK TAILPIPES DO NOT GET TOO HOT WAY BACK THERE. YOU COULD ALWAYS COULD PUT SOME HEADER WRAP AROUND THAT PART OF THE EXHAUST ALSO.

Has anybody had a 17 inch spare on there 18 inch truck 

 

 

The factory spare for all wheel sizes is a 17 inch wheel already.  Stock spare tire is either 255/70R17 is used for trucks with 255/70R17 tires or 265/70R17 which is used on trucks that came with 265/70R17, 265/65R18, 275/55R20 and 285/45R22 tires from the factory.

I have 275/60/R20 mounted on my 2014 Silverado 1500 LT, with a 265/70 R17 10 year old spare.... i need to chage the spare because of how old it is...what is the closest size spare i can get to my mounted tires that will fit under the truck, that will allow me to use the spare tire for the remainder of my trip if i ever get a flat on the road? I guess the question is can i fit a 275/60/R20 under there? If not what is the closest to that size tire i can fit?

I've read on other forums that a 33" overall diameter tire will fit. That is the largest that will fit in the spare tire location.
These are all approximately a 33" overall diameter tire.
285/70/17
275/70/18
275/60/20

 

FYI - 17” wheel is the minimum that will clear the front brake calipers on 2007.5 - 2025 SUV and trucks. If you have the big brake kit (uncommon option) I believe 20” wheels minimum to clear the oversized front rotors that were offered as an option on RST trims.

      BAK MX4 EZ-Lift Install and Review

      By parthery · Posted

      I've been eyeing an upgrade to my tonneau cover for a bit now.  Intrigued by the BAK MX4 EZ-Lift with the torsion spring and went for the upgrade.  Thoughts and musings during unpacking, install and a few days of usage.   Once my order went into Realtruck, it took about 4 days to ship.  Unfortunately, FedEx Ground destroyed the box and contents and it was unusable upon receipt.  To Realtruck's credit, one email with pictures and an RMA was sent to me to send the first one back, and another unit was shipped out.  It arrived 3 days later, unscathed.   I opened the box and it looked like every other BAK MX4.   Biggest differences are the rails and retaining clamps, and of course the spring attached to the cover itself.     NOTE - if you are upgrading from a MX4 to the EZ-Lift, you will have to replace the rails.  The EZ-Lift rails have a notch cut in them to allow the new style retaining clamps to fit properly.  The new retaining clamps also have 2 knobs/carriage bolts and there are two tracks underneath the front panel. The strap clips are mildly different (more like the Undercover Flex clamps) in that the screws go in from the underside.  Personally I prefer these over the BAK clamps that use the nutserts that are a nuisance to install.  The remainder of the parts in the box (drain tubes, rail clamps, and bumper pads) are standard issue BAK.     I did not replace my front bed seal at the time because it seemed to be in decent shape.   BAK recommends shims on the GM trucks unless you place the clamps on the flanges about 1/3 of the way in from both the front and rear of the bed.  I shimmed the front and the middle, and initially placed the clamps equidistant.  This also turned out to be a mistake, because when I set the cover in place, the new style retaining clamps wouldn't clear the front clamp.   New style clamp inserted in the track:     And the issue which occurred because the front rail clamp was too far forward:     Once I removed the shim from the front of the bed, and slid the clamp back to the front flange, everything cleared fine.     The cover set on the rails without issue and I installed the strap clamps.  After I completed my adjustments, I pulled the pin to activate the torsion spring.  Mistake #3 on my part.  PULL THE PIN AS THE VERY VERY VERY LAST STEP!  The reason is, once you pull the pin, the torsion spring is activated.  If you have to loosen the front clamps and adjust the cover, the front panel will - by virtue of the spring, refuse to lay down.  The only way to get it to lay down so you can reinstall and tighten the clamps is to fully open the panel against the back of the cab, which will then allow the front panel of the cover to lay down and be tightened.  Not a big deal unless you haven't installed the foam pads yet (typically the last step) because minus the foam pads, you will need to place something between the frame of the cover and the back window so it doesn't get scratched.  The next time I install one I will install the foam pads before I pull the pin and activate the spring.   After using it for a few days:   The spring assist is great.  You literally can open it with one hand.  My shoulders aren't getting any younger and this was part of my motivation to swap out. The second panel latches and unlatches itself as you open and close the cover.  Neat in concept, however it took me a minute to get used to closing the cover and not hearing the "latching" sound that would tell me it was locked in place. The paddle handles are a huge upgrade and I wouldn't be surprised to see them become the standard across the Realtruck line.  They effectively eliminate the concern that a thief could coat hanger the cover open and get to the contents in the bed. I'm not sure why the very front panel on my cover has a different finish from the other 3 panels.  I have a request into Realtruck to find out if mine was not manufactured properly or if it was by design.   All in all I'm pleased.  Same level of protection, looks good, keeps stuff mostly dry (they all leak around the tailgate) and easy to install.
