Rear foam tyre option for XRAY 389581 M18MT

Upgrade your handling with the XRAY 389581 M18MT Rear Foam Tires, featuring a compact high-density foam profile for improved response. The 25-degree white compound keeps traction consistent across a variety of track conditions, helping drivers dial in predictable rear-end feel.

Purpose-built wheel and tyre pairing

These tyres sit on 34mm-wide XRAY Starburst wheels designed with a slightly softer wheel wall to aid tyre compliance. Pre-trued from the factory, they allow fast installation and immediate track testing.

Installation and setup tips

Specifically matched to the XRAY M18MT chassis, these foam tyres fit without fuss and accept routine adjustments. Use a HUDY Tire Truer with the correct adapter to fine-tune diameter and roundness for local track grip conditions.

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.

Can I use these tyres on non-XRAY wheels?

They are optimised for XRAY Starburst wheels and the M18MT hub. Fitting them on other wheels may require adapter rings or machining and could affect performance.

How often should I true foam tyres?

Check tyre roundness before each meeting and true as needed. Small, frequent truing keeps balance and contact patch consistent without removing too much material.

Do these tyres need any prep before first use?

They come pre-trued, but some drivers lightly scuff the surface or check diameter against a reference tyre to match front and rear behaviour for their setup.

Will wheel width affect handling?

The 34mm wheel width is chosen for a balance of sidewall support and tyre footprint. Wider or narrower wheels will change contact patch and tuning characteristics.
