Spare Tire Question

[SilveradoSaver]

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.

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.

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.

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.
