Full sized spare?

[Capsaicin]

Picked up a huge bolt on the way to work today and the tire went completely flat in less than 20 minutes. Currently rolling on a spare.

Anyone able to put a full sized spare in the spare tire well? Was thinking of buying a single PPV steel 20" wheel and seeing if it would fit. Anyone have experience with this?

'22 Tahoe.

In that case, I don't see why it wouldn't fit. Size is within an inch or so in diameter of the stock spare and width isn't a limitation since there's nothing underneath. Why not pull one off yours and test fit before buying another wheel/tire?

Size it with your repaired tire and wheel before you put that spare back in its place.

Diff between the stock 265/70R17 temporary use only spare and the stock 275/60R20 is about 1.4” diameter. I looked under my Yukon XL, seems like it would fit, as there appears to be about an inch of room all around the current spare.

I might be tempted to go with an OEM Aluminum wheel to save weight. And if you match it to your OEM rims, you could include it in the rotation and get a little more life out of your tires. The 275/50R22 is almost the same diameter as the 20” size.

Although, pg 358 of the owners manual implies it won’t fit. See attachment:

275/55r20 is what the PPV runs which why the rumor i heard made it found like it fit. So its not the wheel that decides, its the total diameter. Boo.

Well, I've had no problems so far running full size spare tires on my 2015 Tahoe LTZ; utilizing the rear underside/winch storage area.
@WalleyeMikeIII posted pg. 358 of the owners manual, but that is states about storing a flat tire. I'm hoping this does NOT apply to an aired up spare...knock on wood. Gonna ask the dealer about the spare next time I'm in, that's for sure!

I've had an OE 20" wheel with LT275/60r20 (33.25") and am currently running an OE 18" wheel with LT295/70r18 (34.29") spare.

With it being the new model, with the flat floor, I thought the reason they went with a space saver was because they no longer had the depth from the flat floor, causing the spare tire in full size form, to be low?
