High speed 1/5 tires?

[Banana RC]

Anyone aware of good high speed tires for 1/5 scale?
The GRP are small diameter for something like a 1/8 or 17 scale. Looking for something with a larger diameter for a 1/5 scale.
I came across the Louise X-Rocket but have not seen anyone using them over 50mph. At nearly $200 usd a set I'd like to be sure of the quality/capabilites.

Currently I am running the MadMax 1/5 super grip wheel/tires and have hit 71.5mph but they are stretching bad "pizza cutters"
I am considering having some custom foams made but wanted to check if I was missing some other option.

Thanks,

I am looking for some too for my Kraton 8s. Going for 100mph plus with a 12S rig. Have you had any joy ?
