Best foams for stock tires?

[redbarton]

I have a sport kit and will be using the stock tires with some cheap eBay beadlock wheels. What would be the best foams to use for trail running? If applicable, what size and foam firmness?

Edit: I'm leaning toward some Crawler Innovation Lil Novas, but I'm not sure which to select. Or, maybe some cheaper options if anyone can recommend something?

Nevermind. I found the following thread:

Trx4 Tires

I'm going with the Pro-Line 6173-00 Single Stage foams instead.

I am VERY happy with Proline dual stage in stock trx4 tires, especially with the small center lugs clipped. I think they may be my favorite tire - or at least equal - to G8 TSL, Hyrax and RockBeast.

I would suggest CI medium all around.

I ended up finding some Proline dual stage foams in a local hobby shop. I'm still finishing the build of my sport kit. It's been a slow process. I have 3 of the four stock tires mounted up on some cheap eBay beadlocks. That's a lot of work between cutting out the small center lugs, washing the tires, stuffing the foams in and then putting together the beadlocks. Phew!

Either the prolines or the CI 'novas are good. Match the density to the rig weight. All of my rigs are in the 6-1/2 to 7-1/2 lb range.
I run CI's in all mine - some standard inners and lately some comp-inners. I do find the outer foam tends to breakdown over time and kind of flatten out, so I've started buying the firm outers.

You also want to match the size to your INNER tire diameter, not outer. I've got some 4.5's in XL size tires, like my KM3's, and they work super well - just the right amount of sidewall squash to match about 8psi on a 1:1. Not what I would likely do for a trail rig - single stage work fine for that, but for comp-crawling in the rocks it's super effective.

I had a set of SSD steelies, so that's what I put on my sport chassis. They're super easy to mount up and look and work great. I also have quite a number of 'chanquish' knock-offs and they all work very well.

I have I.C. CWR-3005(single stage foam 1.9 XL tires) in my stock tires,they seem to fit fine but are way narrower the the stock tires
