Correct foam width for CF MT tires? - Chitown R/C - Chicago's Largest RC Car and Truck Community

DAVEC-NITRO-RS4 · (#1 (**permalink**))

The foams that come with Proline Crimefighter MT tires are 3-3/16" wide. The tire is 2.72" wide. Do you have to trim the foams to 2.72" width to fit the tire properly?

Second part of the question: If using three parts foams, like Racers Edge foams, do you trim the outside rings, or the center ring, to get to the proper width?

Thanks!

Roc, you gotta be kiddin' me man!! That RE foam is a full inch wider than the tire!

Read the same thing that Rocco's talking about. Stuff them in there Dave. Should work out great.

Foam is squishy. No biggie if it's a little bigger than the tire

Those RE foams are Maxx sized and the CF's are narrower than Maxx tires. I'm gonna trim 'em down to the same width as the PL foams that came with the tires.

Never force anything, there is a properly sized hammer for every task.

I wouldn't cut them Dave, I cut my Trinity 3-stage foams to fit better and now the foams seem too small. They move around in there in the turns and stuff.

If you do cut, cut a very small amount. Personally I wouldn't cut them at all.

I fpro racers are doing it... its good enough for me... Jam it in!!

Like I said before, I gotta think proline knows what width they want in the tire, and that's the foam they include.

I am going to trial fit the tires with the RE foams forced in there and see if the tires are bulged. If they are, I'm trimming them to proline width for glue up.

Just fit one up and to me it looks like the sidewalls are really pushing out. I'm going to radius the edges and see how that looks.

The foam they include with the crimefighters is junk! Learn from my mistake. My tires have flat spots because of the crappy stock foam. Rocco will be me up on it, as he saw it first hand. I'll be pulling those tires off the rims and changing out foams (shoulda done it right the first time, but oh well).

I used Trinity 3-stage and cut the center foam before glueing. I cut off about a 1/4 of inch off. I have almost a gallon on them and the foams are as good as the day I put them in. Very tight in the tire and very firm.
