GPM Hyper 7/MP7.5/ Micro middle-shape rubber tyre with insert BUGT895M - MP9/RC8  [BUGT895M]

Micro mid-shape rubber tyre with foam insert

Delivered as a matched pair, this micro mid-shape rubber tyre suits Hyper 7, MP7.5, MP9 and RC8 style on-road cars. The middle contour narrows the effective contact patch and alters sidewall flex so you can tune traction and steering balance without modifying wheel geometry.

Fitting is typical for on-road wheels: install the insert inside the tyre before mounting, ensure the bead seats evenly and wipe off any excess glue. Small trimming or wheel balancing may be necessary to cure vibration after fitment; allow adhesives to dry fully before driving.

As a tuning tool the middle-shape changes mid-corner grip and transient response. You will likely need to tweak damper settings and toe in small steps, then evaluate on short runs to judge handling changes.
