      If you still have a set of the BW15-275-093-375 or BW15-275-093-450 consider yourself very lucky. For those that do not the CB Design Insert Wheels (15 x 7mm) PART NUMBER IW1507S are an appropriate and cost effective aluminium wheel to use in any of the following classes:

      • Sportscar
      • Classic Stock Car
      • Trans Am
      • 1960’s Grand Prix (Group 2 Cars – ONLY)
      • Classic LeMans (for any car taking narrow wheels, such as the Carrera 6)

      Some of the confusion stems from the fact that for the CB Design line of 15″ wheels it is unclear what the 15 stands for (likely scale 15″) added to the fact that with each wider version of the 15 series wheel the overall diameter changes. The IW1507S measures 14.06mm in diameter and 7mm in width which accords with our R32 rules for these classes. Other wider versions of the 15 series may be too large in diameter and therefore not permitted under R32 rules. (The reason stems from the fact that in any fixed gear class you can change the gearing by using a taller wheel/tire combination.) Nevertheless the IW1507S remains a competitively priced, readily available and safe bet alternative to the old BWA wheels for each class listed above. It makes sense to buy a bunch and then know that they are eligible for several of our classes. Of course there are other makes and types out there, some of which are also eligible for some of the classes listed herein.

      The IW1507S takes any DArt D8 or D9 tire (or other Ninco classic alternative). Glue on your tires for best performance – when gluing make sure that the rib in the tire is tightly set against either side of the rib to ensure there is no wobble. [One difference between the BWA wheel and the CB Design wheel is that the wheel ‘rib’ is a hair narrower on the CB than the BWA.] If you do not wish to glue on your tire then the NC0202 or SC0805 tires are the most snug fit. No truer? Then stick to the NC0202.

      You can try your luck at RaceHaven if Ron has them in stock, or at MiniGrid, or you can order from Slot Car Corner Canada at:

      I now have inserts to fit these wheels. The inner diameter for sizing inserts is .490″ (or 12.45mm). There are three insert wheel styles which fit these wheels: 490steel60; 490mag5snut & 490minilite, but more will be added over time.

      Note: These wheels may be listed as ‘made in Canada’ but there is nothing Canadian about their manufacture, nevertheless they remain a suitable and well performing alternative for several of our classes and therefore worth suggesting here.

        Unfortunately Slot Car Corner Canada has closed its doors. You can still get CB Wheels at Slot Car Corner in the USA.

        CB Wheels are a bit lighter than RS-Slots (not always an advantage). A bit heavier than Slot-It. But have more range of sizes than Slot-It. CB Wheels also offer some odd sized diameter wheels. Check the actual wheel measurements on their chart/site before buying. Just because it says it’s a 14×7 wheel doesn’t mean it’s 14mm diameter (it might only be 12mm).
