Reinforcing soft rubber tires

[sjordan2]

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?

Fill them with Silicon like you seal a bathtub with.

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!

Pack them with cotton balls.

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

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?

Any Home Depot or similar hardware store should carry backer rod, which comes in various diameters:

Lots of good ideas. Thanks.

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.
