Performance rear foam tyres for XRAY 389581 M18MT

The XRAY 389581 M18MT Rear Foam Tires use a dense foam mix and a 25-degree white compound to produce steady rear traction. These tyres are aimed at drivers who want consistent feel and durability across laps.

Wheel design that helps grip

Mounted on 34mm-wide XRAY Starburst wheels, the tyres benefit from a slightly softer wheel design that improves tyre compliance and lateral hold. They are supplied pre-trued so you can get on track without lengthy prep.

Compatibility and trimming options

These foam tyres are cut to suit the XRAY M18MT chassis and install easily. For those who tune aggressively, a HUDY Tire Truer with the appropriate adapter will let you dial in exact diameter and roundness for specific track conditions.

Specifications

  • Tire Compound: 25-degree white

A practical upgrade for M18MT owners, these XRAY foam tyres balance traction and wear for regular race use and setup development.
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 tyres ready to race out of the box?

Yes, they arrive pre-trued to a sensible starting diameter, though many racers check and fine-tune diameter to match front tyres or track grip levels.

What maintenance keeps foam tyres lasting longer?

Avoid aggressive glueing that distorts the tyre, store away from heat and sunlight, and true lightly rather than removing large amounts in one session to prolong life.

Can I adjust tyre diameter for different tracks?

Yes, use a truer like the HUDY with the correct adapter to reduce diameter incrementally. Smaller diameter can increase responsiveness, while larger helps stability.

Will these tyres require special glue or inserts?

They mount to the Starburst wheels without inner foam inserts; standard foam tyre glue or contact adhesive used for foam tyres is suitable. Follow wheel manufacturers guidance when applying adhesive.
