XRAY 389543 Medium Rear Foam Tyres for Consistent Traction

What Makes XRAY 389543 Rear Foam Tyres Stand Out

  • Hex Hub Design: Tailored to hex adaptor wheel setups to reduce slop and keep torque transfer direct.
  • Medium Density Foam: Provides a predictable contact patch that resists rapid wear while maintaining traction.
  • 40-Degree Hardness: A neutral hardness that performs across a wide range of indoor and outdoor smooth surfaces.
  • Set of 2: Supplied as a pair for easy swapover on the rear axle at the track.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Are these compatible with standard hex adaptors?

Yes, they are made to mount on standard hex adaptors. They are not compatible with the original M18 wheel mounting without modification or adaptor.

Which driving style suits these foams?

Their medium compound suits balanced driving and aggressive corner exits alike, giving consistent traction without excessive wear for most club track sessions.

Can I glue these to aluminium rims?

These come mounted on hex hubs. If you plan to transfer foam to different rims, use a foam-compatible adhesive and ensure the hub and rim interface matches your setup.

How do I know when they need replacing?

Look for flattening of the contact patch, chunking, or a noticeable loss of grip. Replace them as a matched pair to keep balance.
