I am looking for a wheel adapter that will let me use modern wheel/tire combinations with my Ultimas and Optimas. I've seen a couple of parts on eBay that claim to do this, but none look very durable. Any experiences/recommendations?

Thanks!

Follow what mikedealer posted and you should be fine, for the new 2.2 wheels the new axles spin on two bearings, not the wheel spinning on the bearings, It's kind of weard. He has all the part numbers for Koysho America in his writing. Here is the how to for the wheels

and here is the site for Koysho America

and here is a couple of pictures of my Ultima Pro with the 2.2 wheels un-cut on the front end.

Thanks! Did you have to adjust the gearing at all to accommodate the new larger tires?

BTW, those wheels look awesome...which ones are they? I even like the tires too...can you post the brand/part #s if you have them?

Thanks again.

Those wheels are HPI super star for the super nitro RS4 and Kyosho Super Ten cars. HPI PN's 3031,3032,3033 (not sure which PN is which, but they come in grey black and white). Chrome also - don't know that PN though.

The chrome one is actually HPI 3032 - 57mm x 35mm with 12mm hex standoffs.
