They also get turned into shoes.

Tires can also be recycled into armor.

While not quite as aesthetically appropriate kevlar/aramid reinforced conveyor belt has numerous benefits over tire rubber. Stronger, lighter and available in large lengths.

Noice. Been thinking about what would get repurposed first. Improvised body armour is a no brainer. But how would it be stat'd?

BTW, berms made out of soil/rock filled stacked tires is so appropriate. Ta muchly.

For example, some research shows that steel-belted radials are about DR 10 per .25 inch thickness. In David Pulver's armor system, they would have a stat line of:


Code:
TL  Material                       WM    Cost  DR/inch  Max DR  Notes           Construction
6   Steel-belted Radials	   0.2	 $0.00	  40	  20	C, F, S*	segmented plate, scale, solid
So many tires lying around, you should be able to get the material for free with a scavenging roll. Then its an Armoury (Body Armor) roll at +3 and 3 hours work per 100% coverage to get steel belted radial lorica segmentata at DR 10, semi-ablative, combustible. 20.3 lbs for torso, groin coverage. Maybe slap it with -1 DR without a really good roll on your Armoury skill check, as it will come out "Cheap".

<SNIP>
These number are I think based on a 1/4 inch thick tire being about DR 10. At a guess add 2 DR (4 ply kevlar replacing the steel belt). Maybe reduce weight by 10%. Easier to work with than tires. Numerous specialized types exist (chemical resistant, heat resistant, etc). I would personally drop the semi ablative aspect.

Those stats for using radials for armour give it better DR/pound than RHA, and DR/inch better than good aluminium armour and the same as good kevlar. Your suggestion for the belts makes them better than all but the best TL8 flexible armour in terms of DR/inch, and better DR/weight than all TL8 rigid armour other than 'Improved Ceramic'.

If steel and kevlar reinforced rubber was this good it'd be used for body armour and vehicle armour already.

A quick perusal of youtube videos shows people putting 9mm hollow points through the tread of steel-belted radials, and through sidewall and tread (and that means the bullet is going through the tread at quite an angle, which is bad for penetration). That makes a normal steel-belted car tyre tread about DR4, and the sidewall probably DR1, and that's being fairly generous, IMO.

If you cut/sanded off the tread to make layering easier you'd be getting about DR16/inch from the belted part vs bullets. Cutting-Edge Armor Design (Pyramid 3/85) gives straight rubber DR14/inch and 0.45 ibs per DR per ft^2, but it's halved vs all but crushing. I'd be good with improvised armour from belted tyres better, but DR32/inch as the base seems excessive. It should retain the properties of rubber - combustible and semi-ablative, but the 'half vs non-crushing' could be removed, with the assumption that the steel doesn't help vs crush damage, but does vs other damage types. Then we can stick with DR16/inch, and go with that 0.4 lbs per DR per square foot.

A kevlar belt should be worse than the kevlar in CEAD, and thus weigh more than 0.1/DR and give less than 33DR/inch. It should also keep the limitation of being terrible (1/4 DR) against anything but cutting and piercing damage. Also, all kevlar armour should be semi-ablative if you're being realistic about it (as should ceramic inserts), but if you don't bother tracking this for normal body armour not bothering for the improvised stuff isn't unfair.

So, kevlar belts will be good vs pistol bullets, and types decent vs melee weapons, especially blunt ones, but otherwise it won't be great armour - as you'd expect from improvised pieces. A good all-round improvised vest might be conveyor belt cut so it warps around the torso well, with strips of tyre tread on the outside over the shoulders and front for added impact protection. Stripe them vertically or horizontally as your sense of aesthetics dictates.

Ta muchly.

The later may be dictated by Vicky's Monastic ćsthetes... one of the more curious groups of the Wastelands...
