exhaust shop, melt spare tire?

Chopped as little as I could a while back, for whatever reason
-clearance
-hide it
-seemed weird having the exhaust tip be so low and wrapped around (HC bumper)

and moved the spare to the bed, locked and ratchet strapped to tie-downs

as a bigger 33', it's quite the difficult squeeze to fit in stock location
I want to try and shove it back under the truck, to make room in the bed

Is it too late at this point, given the chop? Would it melt the tire?
I honestly don't think so, because:
With the truck warm, I got underneath and eyeballed where the exhaust would exit relative, and put my hand to feel where it goes and temperature
even sitting without moving at idle, it didn't feel hot or like it'll cause an issue with the tire



I do need the bed space so honestly I'll probably just try it and see what happens. Worst case scenario can go to an exhaust shop for a slight extension, or turndown tip facing another direction for hopefully cheap

 

I'd imagine it would take a lot of heat to melt a tire. Spares are cheap enough anyway, send it.

 

That looks exactly like my “chop” and I’ve had my 33” spare there for years even with LOTS of idling hours. You could always add some heat shielding. Easy peasy. Even some aluminum foil would work to test things…

 

If you’re worried you can get flexible clamp on tubing at a parts store and make a cheap angled exit. It won’t look pretty but no one can see it anyway.

 

gonna send it, thank you all

wanted to mount a WaterPort daytank and make a bed platform with sliding storage drawers, potentially using kid snow sleds
Or BamBed

and it was the spare in the bed really getting in the way of that
Not running a swingout tire carrier yet

 

Granted this is a pic of my rear with the spare removed, my chop was closer and I never had an issue

 

You'll be fine.

You may have to move the hanger back one set of holes to get it to clear the diff.

 

Almost a year on the tundra with the dump right next to the spare. No issues

 

With the amount of length piping that runs out to the rear it/ they would have to be touching the tire and be on it for a very long time to melt it.

Full send.

 

Anytime your exhaust temps are high enough to melt the tire you've got bigger problems

 

i have the stock tire. but ive a similar chop and it looks good, and ive seen a 33, well a 285/75 16 there

 

You're not going to melt the tire. BUT... excessive heat and sunlight will accelerate the rubber breaking down. Since most spare tires are not exposed to sunlight they generally hold up longer than the tires on the ground. They recommend replacing tires between 6-10 years old because of this. I wear out a set of tires long before 6 years, but I've left a spare under the truck for 10+ years before.

The excessive heat from the exhaust MIGHT lead to some long-term breakdown of the spare. It might not get hot enough to cause any problems either. But that is the only potential problem I can think of, and it may not even be a problem at that.

 

My exhaust runs right by the tire too, chopped pretty close to it. I think it has a bit of shielding there too. No problems to report. 33" tire too... 285/16.

But the reason I'm writing is to suggest more generally, in these modern times, if you're worried if something will get too hot, you can use a thermal camera to find out. You can find cheap thermal cameras that plug into your phone. It has a ton of uses. I remember thinking it would just be a fun waste of money when I bought one, but I turn out to use it on all sorts of jobs, I'd say it definitely paid for itself by detecting and preventing problems. Engine bays, heating and air conditioning, hot and cold water plumbing, circuit boxes, wiring, circuit boards... it's amazing what temperature can reveal.
