That seems like an excellent suggestion. I started doing some research to see if it would be a viable solution, but I need to look into it further (or get additional information from forum members) before I’ll know one way or another. Based on information I found on the thread linked below, the original steel Coker rim was close to 3lbs heavier than the subsequent aluminum rim. In addition, the original Coker button tire was claimed to be around 5lbs, though I believe it is closer to about 3.25lbs. So depending upon the weight of the tire I get, I may need to add anywhere between three to maybe three and a half pounds of weight to the wheel (in the vicinity of the rim).
I haven’t done too much research on the puncture-proof liners yet, but the two brands I found quickly on Amazon (linked below) are about 3.5oz and 3.7oz per liner, respectively.

Since I probably need to increase the weight of the aluminum rim I purchase by at least 3lbs, I’d need nearly 13 of the heavier 3.7oz liners to achieve that additional three pounds of weight. As such, I assume that you’re probably suggesting that I add lead weights or something similar and then place the liner on top of the lead weights (or strips of code-4 lead flashing) that were suggested by the other forum members, is that correct? I don’t see how it could work any other way unless there are much heavier puncture proof liners on the market. If that is the case, I would be most interested in any information on the heavier liners (if you know of any) in order to save me the time of searching to see if I can find them. Even if I wind up having to use weights or a weighted strip, adding a liner as well makes sense, so your suggestion is quite good and I appreciate your input very much.
