Notable Points for XRAY 389543 Rear Foam Tyres

  • Hex Hub Design: Engineered to work with hex adaptor wheels to maintain a secure interface and minimise slippage.
  • Medium Density Foam: Gives a steady mix of traction and service life for both practice laps and race days.
  • 40-Degree Hardness: A balanced compound that adapts across indoor and outdoor smooth venues.
  • Set of 2: Packaged as a pair so you can change both rear wheels quickly and keep handling consistent.
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.

Will these mount on my hex adaptor wheels?

Yes, they are intended for cars that use hex adaptors. They will not fit vehicles that rely on the original M18 style wheel mounting without an adaptor conversion.

What are the best conditions for 40-degree foam?

This mid-hardness foam performs reliably on carpet circuits and smooth tarmac tracks where predictable, steady grip is required.

How should I pair these with my setup?

Fit as a matched rear pair and check balance with your existing front tyres. Adjust suspension or toe settings to fine tune rear traction if needed.
