fix bent rims & chunked tires
I've been saving some bent rims and chunked tires for a while, hoping to come up with a way to salvage them. I went to a glass blowing show and was watching and it hit me to try something.
When I got home, I took the tire truer out and got my map gas for my torche. I put a bent rim on the tire truer, turned it on and lightly hit it with the heat from the torche. The rim, started to "fix" itself, but with a little help, I was able to save 21 front tires. They may show a little "discoloration" from the heat and dirt that I burnt into the rim, but they are smooth and round again.
Then I had some chunked tires. Nothing new for us, but don't you hate it when you chunk a tire when its new. Not a problem anymore. I found a tire cement #902 from TRC. cutting a squar chunk from the tire and one from a donar tire with the same shore foam, I globbed on the glue to oriinal tire and placed the donor piece and put a rubber band around it to hold. after about 30min, I took the rubber band off and trued the tire down smooth. With this cement, there is no hard ridge like when using CA. I even chunked these tires again and where the new chunk came from, it tore into the patched area, but didn't take the patch out.
I was able to salvage a total of 27 tires in about an hour.
(I could just learn to drive better and not hit things,
and save the Hour)

Thanks for the suggestions. Reduce/reuse/recycle also means savings in $$$. One may also buy new donut rubber too by remounting to old rims. This is a good time of year to be getting ready for next year.

Very good idea about fixing bent rim and chunk tires....for chunk tires, I use CA and dremel sanding drum to sand it off....take a little bit more time then using a tire truer...but sanding drum can sand off the extra foam very nicely.
The way I fix my bent rim.....easy, return them to the tire mfr....I did that on JACO and GQ....they replace me the new tires. including CRACK rims, these 2 tires MFR are very confidence about their rim construction and they will fully support their products....of course, those rims that I am returning are usually very NEW rims....they are defect rims, if you have some rims that are cracked and bent with barely any foams left...forget it, that is not under warranty.

I have never tried to straighten wheels, but I do repair my chunked foam wheels. I race a 1/10 scale Custom Works GSX nitro sprint car on a oval dirt track. With the speeds we are traveling, minor contact with another car results in some dandy chunks in your tires. I take my tire truer and mount a tire that is chunked. I then cut the bad section off ( a complete ring ) and remove it from the wheel. I remove a similar section from another chunked tire and glue it back on to the first wheel. You end up with a multi-ringed tire similar to some of the high end tire manufacturers. Contact cement works good for this. I also have a larger Out Front Frames sprint car that I build rear tires for. I use 1/8 scale on-road foam donuts and wheels. The foam is always about 3/4 inch wider than the wheels, so when I trim off the extra width, I save it to make repairs with later on. A tire truer is the best piece of RC equipment that I have ever purchased.
