sjordan2 Posted August 30, 2015 Share Posted August 30, 2015 I have a 1/16 Jag XJ-S that has flimsy soft rubber tires that I can almost guarantee to flatten out over time. Any experience out there in firming them up on the inside? Quote Link to comment Share on other sites More sharing options...
wilderness1989 Posted August 30, 2015 Share Posted August 30, 2015 Fill them with Silicon like you seal a bathtub with. Quote Link to comment Share on other sites More sharing options...
Pete J. Posted August 30, 2015 Share Posted August 30, 2015 I go to my local R/C shop and get the foam inserts that they use in R/C car tires. I have used them on the Tamiya 1:12 935 tires and they hold up nicely! Quote Link to comment Share on other sites More sharing options...
Cato Posted August 31, 2015 Share Posted August 31, 2015 Pack them with cotton balls. Quote Link to comment Share on other sites More sharing options...
Tom Geiger Posted August 31, 2015 Share Posted August 31, 2015 (edited) cotton will depress over time. Who knows if there will be a chemical reaction from silicone, Do what the demo derby drivers do.. fill them with sand Edited August 31, 2015 by Tom Geiger Quote Link to comment Share on other sites More sharing options...

Who knows if there will be a chemical reaction from silicone, Do what the demo derby drivers do.. fill them with sand The cotton I advised Skip about, which is in my GT-40 tires has not depressed in 5 years. Nor my 935 after 26 years. Has it happened to you? Quote Link to comment Share on other sites More sharing options...
Casey Posted September 2, 2015 Share Posted September 2, 2015 Any Home Depot or similar hardware store should carry backer rod, which comes in various diameters: Quote Link to comment Share on other sites More sharing options...

bismarck Posted September 2, 2015 Share Posted September 2, 2015 I use that silicone rubber tubing Cut to your need diameter, make a small connector, and presto. Won't react with the tire over time either. I get mine from work, but you can pick this stuff up pretty cheap at any craft store. Quote Link to comment Share on other sites More sharing options...
