DIY half-assed dual-stage foams

[durok]

This example used 1" wide cheap 2.2"wheels and 4.5" tall RC4WD Dune T/A trophy truck tires, they will be used on hardpack and possibly a little pavement.

The concept should be workable for many other applications, however.

Take one 11/16ths-inch wide beadlock inner ring and a roll of 5/8ths-inch wide weatherstripping, wrap the ring with the self-adhesive closed-cell black foam weatherstripping and CA-glue the ends together.

Then insert into low-profile tire with relatively soft stock foam and clamp front and rear beadlock wheel faces together.

Presto, half-assed dual-stage foams!

This idea really only works for either lower-profile sidewall tires or smaller than most diameter wheels and tires because you can't build up enough of a stiffer inside section with weatherstripping to make a noticeable difference in a large volume tire.

I'd imagine it'd work great in many 1.55", 1.7", and small diameter 1.9" tires, however.

If you can't afford or find real dual-stage or stiffer single-stage foams, using weatherstripping foam as the first layer will still allow you some additional firmness in the center of the tread.

If you found thicker and/or wider weatherstripping foam, you could make a more functional setup, especially if you have a wider wheel - this would help more for sidehilling and turning at speed.

I did this because the stock RC4WD foams were very soft, and I was using very narrow wheels - wanted to get just a bit more stiffness without going the extra mile of buying aftermarket foams.

Every little bit counts!

I read that thread when it was posted, while very creative and also functional - this is a different method.

The closed-cell EPDM sponge rubber used in weatherstripping is extremely dense and has rebound.

I have been eyeing my roll of it for many months, waiting for a wheel/tireset where it would come in handy.

Yes it is. It’s so dense that it seems to me that it would be almost like running a larger wheel with a recessed bead. (Makes sense in my head) I like where you’re possibly going with it though.

I tried that my issue was when they got wet they lost there stick and end up floating around inside the tire
