Timtin 4 Pcs Dual Stage Closed Cell Inner 1.9 Inches Soft Outer Foam Inserts Car Crawler Tire Foams Wheel Inlay Foam Sponge for 1.9 Inches Wheel Tires Rock Crawler Car Axial, Blue

Ok, when you first pull them from the tight plastic bag, they look distorted or poorly cut, but take them apart and let them sit 24 hours to regain original shape (see before and after pictures). These are sized to fit XL tires approx 4.75 `s. The inner sidewall foam is not cut with precision like Prolines are, but in the end, I dont think it will matter for a crawler, Also, the inner blue foam is 1/4 inch wider and fills up the side walls of your tires. I am running the Proline 4.75 "Krawlers" and they fill the side walls as opposed to the Proline Dual Stage that leave some space. I kinda like the sidewalls being filled out better. I can tell it's going to help save the rims from damage because the side walls are pushed out to full form. You will still need to vent your tires to get the best "Aired Down" traction. ...Also, the inner blue foams fit tighter to the inner beadlock ring...So much that they dont slide "side to side" like my Prolines do... I think these will work pretty good by the looks of it...

Got 2 sets. Cheap but good. Not the prettiest things to look at but there inside the tire so I don't care they do the job. Outer Foams are alittle deformed from package take them off the inner foam and hit them with a hair dryer or heat gun quick and they go back round.

They arrived a bit deformed, they performed great, these should be listed for 2.2 inch rc tires as well. They're a very tight fit on 1.9 inch 120mm tires though.

If you’re in the market for duel stage phones, do not waste your money on big name brands. These are top-notch.

Oops. Thought I was buying proline. They are not. They are decent though. Kinda stiff. A little more so than I'd like or expect but working decent ,. Way better than my old worn out foams. Sidewall strength is stout. Not much give, so sidehill work is great. Out of the package they aren't round. They are kinda packed too tight. Take the outter ring off and let it set for a bit. It'll come to round again. But really its not gonna matter if you're not obsessive. Pretty snug for for my 1.9s, but no mounting issues. So far,. Good for the price. We'll see how they hold up.

These are shipped in a bag 2 sizes too small!! The foams have been sitting out for a week, and they're still smashed and flattened in spots?! Terrible quality, just bust out the bucks and buy the quality brand, you'll thank me later.

I’ve tried several different styles of foams. These are absolute junk. I would recommend spending $4 and getting the proline version

Tire feels soft but sturdy and no side flex.
