foam inserts. what do i do?

[Ryu James]

can anyone please tell me what to do when you get a tire and foam insert setup like these panthers? do you cut the foam? doesnt that make your tire off-balance? i have only had tires with molded foam inserts that fit perfectly into the tire. what do i do with this thing?

[_paralyzed_]

open it up and shove it in. if there are fitment issues it can be trimmed(squish it down with a straight edge and cut with a sharp razor blade to keep from getting off balance).

the more foam that's in there, the less likely the tire is to balloon.

amain says that the Panther 2.0 switch tires fit 38 series wheels like the proline LPR. i thought 38 series was the revo 3.8" wheel and LPRs are 3.7". has anyone tried the panther tires on a set of proline LPRs and do they fit snug?
