Rear traction solution for XRAY 389581 M18MT

The XRAY 389581 M18MT Rear Foam Tires combine a high-density foam body with a 25-degree white compound to produce dependable traction. They offer predictable rear-end behaviour that many drivers prefer when fine-tuning their setup.

Design focused on stability

Fitted to 34mm-wide XRAY Starburst wheels, the tyres benefit from a wheel profile that is slightly softer to boost contact consistency. Factory pre-truing means minimal prep before heading out on track.

Installation and setup guidance

Made to fit the XRAY M18MT platform, these tyres install cleanly and allow simple adjustments. For precise trimming, use a HUDY Tire Truer with the matching adapter to set the diameter and achieve even wear.

A sensible upgrade for M18MT racers, these XRAY foam tyres provide stable grip and easy setup for race day tuning.
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 tyres fit wheel rims from other brands?

They are optimised for XRAY Starburst wheels and the M18MT hub. Other rims may need adapters or modification and could change handling characteristics.

How should I store foam tyres between events?

Keep them clean, away from direct sunlight and heat, and store flat or on a wheel rack to avoid distortion. Proper storage stops premature hardening and deformation.

Is truing required before first run?

They come pre-trued for convenience, but many drivers check diameter and roundness and may perform light truing to match front tyre behaviour or specific track grip.

What is the effect of the 25-degree compound compared to softer mixes?

A 25-degree white compound favours consistent grip and predictable wear rather than extreme stickiness. It suits tracks where balanced handling and repeatable lap times are priorities.
