Where can you find low cost high quality foam donuts in white or gray compunds for front and rears?

I have rims and wanted to mount them for practice.

Also what is the best way to mount them? I read that you can apply contact cement on both sides, let dry and then soak'em in laqour thinner and they will slide right on.

When I used to mount them myself way back when I used PL185 (I believe that was the #) wallboard adhesive. You can find it in the wallcoverings area most home improvement stores.

First, take your dremel and rough up the surface of the rim, then apply the adhesive to the rim and carfully to the tire, let dry for awhile, soak them in the laquer thinner for a bit and put the tire on using a tire horn. A tire horn might be hard to find these days, it is basically just a cone though, you could jury rig your own or get by without it probably.

I know RC4less sells donuts, but only in a couple compounds. You could contact your tire manufacturer of choice and see if he'll sell you some donuts.

Mounting your own tires is a great way to save money. I'm not sure why it fell out of favor. Using the PL adhesive gives a better bond than I've seen out of any of the tire manufacturers.

I used the same process as Pat but I used contact cement. That worked good too. I do have a cone for sale if you desire one. Don't know of anyone else that sells just donuts outside of RC4LESS. Could contact someone at TM or BSR.

Back in the day I use to wrap my rims with surgical tap then apply glue to rim and tire. Soak tire in laquor thinner then apply to rim. When done with tire just cit down to tap and peel of. This made a nice clean way to remove your tire with out all the mess!

Right on. Cement both the rim and inside of donut, let sit about 15 minutes til cement sets up a bit, dip the rim, tire and even the cone into laquer thinner for just a second to get them wet, and put the cone over the rim and slip the donut on and get it as straight and even as you can before the thinner evaporates. I usually let the tires then sit a few hours to cure and then true them up.

Thanks all! I will let you knoe how it ends up after a get some donuts.

this is great but aside from not being able to tires wouldn't the rims be tough to find or am i missing something?

Some people like their old rims :)

I never used a tire cone.

You have to start out with a set of of new tires/rims. Then put on new donuts after you wear them out.
You can definitely save a few bucks per set if you are not afraid of a little extra labor on your tires.
