the tires keep coming off the rims on my jammin x1 RTR
I have glued them back on but wherever the factory glue was they keep coming off
OFNA says to change the diffs from grease to silicone oil??
can someone tell me the idea behind this?

also anyone in the Cranbrook area wanting to run the cars let me know

I was told you cant just regue the tires because the old glue wont let it bond right. Do a search for reusing tires or rims and they will tell you how to get them off so you can put them back on clean. From what I read you could either boil them or use nail polish remover but look it up first.

For the diff oil I think adding silicone wouldnt let the wheels balloon as much which wouldnt cause the tires to pull from the rim. (Its just a guess)

Thats correct.
Fill the diffs with silicoe oils will help transfer drive more evenly or controlled compared to grease which makes the buggy diff ie the wheels spin excessively when coming of the ground or under accelleration.Suggest you change the front and center diffs to 5000wt silicone oil and 1000 or 3000wt in the rear diff.

for the jammin 4-6-2 works really well

Ive never tried this, but I was told nail polish remover will remove old glue? Clean off the old glue. Make sure you pull back the tire so you can get the glue tip inside the rim area where the tire seats. Thats where you want to apply the glue. I put a little drop on then push it around with the tip. Drop, push, drop, push until you get all the way around. I HATE glueing tires, but this is the way I do it, and it has worked fine for me. As far as grease vs diff oils/lubes, just like the guys said. It helps you tune how your buggy reacts to when you hit the throttle. You can have it set up so your front tires get power first, or your rear tires. Also the outside tires vs the inside tire (In turns that is) Grease is only one weight, thinckness. You cannot get this type of action with grease. Actually you can if you find/use differnt weights of grease. But then youd be on your own. No one else could help you. Get the diff lubes like they said. They are designed specifically for this. A bottle of OFNA lube costs about 8 bucks. It will last you a long time. The wieghts are entirely up to you, but generally the heaviest is in the center, next lowest in the front, and the lowest weight in the rear. You shouldnt go any higher than 10k in the center. I used to run 5k, 10k, 3k. I was told 10k was too heavy. I said ok, and changed to 7.5k. Didnt have any 7k, so a 50/50 mixture of 10 and 5 makes 7.5. I didnt see any difference.

Try using some zip-kicker. It's makes tire glue dry quickly and strongly when you spray it on. I use it for quick repairs at the track, of which I have very few.

Take a dremel if you have one, a piece of sandpaper if you don't. Lightly sand the rim and tire where they are to be reglued. This should be done before they are glued originally, they don't do it when they come preglued.
