Spare Tire Heat Shield

Does the exhaust really get hot enough to mess with the spare tire? My 18 Colorado has the heat shield and it stands out bad. I'd like to remove it or paint it with high heat black paint to help it blend in. Has anyone doe either idea?

I'm in the same boat.. subbed. I wish there was a way to suck the tire up more into the bottom of the bed so it's not as visible. And no I don't want to put it in the bed..

Several owners have posted about a larger tire, no heat shield and no problems. I wanted to get the spare out from under the truck and use a Hitchgate Offset carrier.

IMO...get the HT black paint fm auto store and give it a few coats...then it will blend in.

If you have a gasser, I don't see an issue. If you have a non-deleted diesel, the spare tire may heat up during a regen. I am guessing they were concerned with the rubber compound in the spare tire getting heat cycled from the exhaust and changing the characteristics of the rubber compound in the spare tire in one localized area of the tire. Probably overkill and realistically has no substantial effect on the tire. If you're worried about one spot of the tire getting heat cycled all the time just rotate the tire a little every oil change.

I initially turned my nose up at the 'Rados over the bulbous spare. I thought it would get caught on high points offroading. That would suck. And it looks like an engineering afterthought.
When I chose the 'Rado for my next truck, reducing the spare profile was a high priority, especially because it interfered with my totally awesome Hellwig sway bar, at least for me it did.
My solution was to get the 18X4.5 "compact spare" GM22890102 that was being supplied with the 4 bangers and WTs.

I couldn't get one from any parts seller or the local dealer parts dude. I think they're discontinued.
I had to lurk around till somebody sold me one (you know who you are, THANK YOU!)

The donut really cleans up the underside. If you look at 'Rados and don't see a spare, it probably has the donut.
I will still throw my full size spare in the bed for extended trips as the default.
Even if you don't need this compact spare, you might still consider getting one if your a long term owner. Its cast aluminum and a very odd size made for the 'Rados; you won't find anything else like it later on. Maybe a steel version if you're lucky. Having said all this, I do feel they went too thin on the donut. I think it could be an inch wider and still not protrude much. Maybe there is no rubber for that?

I washed, sanded and painted the heat shield and the exhaust pipe from the heat shield back. Mainly because I put a black rip on the exhaust pipe and the black/lighter stainless looking color side by side looked stupid. Used black heat paint from the parts store. Gives it a lot cleaner look.

If you use your truck as a "Car" the"Doh" nut is fine... But haul weight, or a trailer,you need the full size spare! My friend found a deal on 4 wheels/Tires alum Colorado WT 4 for $400, with tires had 630 miles on them He Is going to give me one of his Colorado OEM Base Steel wheel for a Full size spare.

No need for high temp paint, regular gloss black on the shield has worked just fine for me.

If there was not a need for the shield, GM would not put one on there. There may be some long uphill incline pulling a trailer where the exhaust temperature might get high but there definitely is a reason that it is there. I painted mine with black VHT header paint.
