use ratchet straps, much easier and safer to use.

 

i'm fixing to go to walmart in about 30 minutes, anything from there you think would work?

 

yup, you can get a good 4 pack of ratchet straps from wal-mart for pretty cheap.

should be all you need.

 

The cover? You're talking about the thin sheet of vinyl that covers the trunk? That's not going to do anything for protection. A 20lb donut will rip right through that.

You can ratchet it down using X or Y or W or whatever, but I really doubt it will hold a full-sized tire down in a wreck. If you're still wanting to do this (I still don't get why you can't get a hitch mount or modify the exhaust.), at least reinforce the D-brackets with something beefier and some gigantic washers.

 

i was just saying that it would offer more protection than it just sitting in the back like it is right now...

 

if the tire is securely tied-down with ratchet straps in an "x" formation, then the tire should not move during the event of a wreck...i mean, think about it: the only times you here of a "projectile" type deal in an accident is when something isn't tied down. when they aren't tied down, then energy can be transferred to them, causing them to be launched towards your head. but if it's tied down in an "x", then no energy should be transferred and it should stay in place...so i say don't worry about altering the already cool exhaust you have or buying some expensive tire carrier, just strap it down...

 

But you might still have to beef up the tiedowns in the cargo area to hold 100lbs of tire from ripping them out and being launched (some engineer on here must be able to calculate the force generated 100lbs, 60mph).

 

well, since i'm an engineering student, i'll give it a shot: let's see, if the 100 pound tire is accelerating at 60 mph, then it's accelerating at around 26.82 meters per second and the 100 pounds = 45.36 kilograms. then, since force = mass * acceleration, you should be able to say 26.82 m/s * 45.36 kg = 1216.56 newtons, which is then = somewhere around 897.33 ft/pound of force. so, in conclusion, you don't want that 100 pound tire hitting you at 60 mph...haha!

 

You really think that a 100lb tire at 60mph would be bad for your health? WOW i would have never guessed! lol

But wow that is even more force than i thought!

 

haha, i know, who would've guessed...haha! and yeah, it sure is a lot of force that'd be hitting you... i didn't think it would've been that much either...

 

Your telling me, i mean i knew it would take out the back seats easy and possibly the fronts as well but that much force would just go right through the back seats the front seats and ram you right through the the firewall into the engine bay!

 

yeah, there's no doubt that if the tire wasn't secure and made it to your head, that your head would be forced through the windshield...hate to think a/b it, but it's all the more reason to secure any type of cargo, especially speaker boxes, as those can weigh more than 100 pounds!

 

but, the full size spares are NO WHERE NEAR 100lbs. think about it. maybe 40?

 

true there...i was just figuring on what they were saying as an example. but if it were 40 pounds, then it would be around 358.93 ft/pound of force. by far not as much, but i still wouldn't want that hitting me in my head...lol!

 

I think he is running a bigger tire on his truck and they can easily be 100lb with steel rims.

 

its a stock 2wd 3rd gen.

 

So it is, i now see that it was someone elses spare that was 100lb that gave everyone that number. The stock still weighs about 50lb+ though.

 

yea i just took the thing out and see if it would go back in the factory location, and thats a big negative. it weights nowhere near this 100 pounds people keep bringing up. also i bought some bungee cables and have it locked down. i plan on doubling them as well. just out of curiousity though, should i also strap down my fold out chairs and tennis rackets in the back?

i guess its a good idea that i didnt plan on adding subs for awhile to lol

 

sure, if you can, i see no reason not to strap it all down, b/c we all know by now that it may be launched at your head, and i really don't want to figure out the force of a tennis racket @ 60mph...lol!

 

securing sub boxes is a good idea also. It is as easy as screwing a handle in each side and ratcheting it down. It sure saves on unwanted short-to-grounds or pulled out grounds as well.
