The shiny Thinderslot tires appear to be some form of Urethane, so like some of the NSR urethane based tires the sidewalls can crack – even with the ‘rubberized’ CA glues (such as those sold for RC tires). Last year I took a clue from Dave and tried ShoeGoo. If you need to glue your T/S tires you can fill the air-gap channel with a bead of ShoeGoo. Bonus – when removing old tires – it takes some persistence but with a really hard tug the Shoegoo comes off very cleanly.
To more fully fill the gap – two 13mm (1/2in inside diameter) faucet O-rings can be used. These are alternatives to the $9 foam-donuts sold by Thunderslot for filling the 14.3mm high gap in the OEM TRMR001AL wheels. The O-Rigs must be trued to match the height of the shoulder ribs – either
14.3mm for the OEM wheels (TRMR001AL) -or- 14.9mm for the Replacement wheels (TRMR002AL). I suggest using an Emory Board for the cutting rather than ruining your rims on a truing grinder-wheel.
#10 O-Ring 1/2in (13mm) inside diameter O-ring (3/32 thick)
#9 O-Ring 7/16in (12mm) inside diameter O-ring (3/32 thick)
Permatex Car Window Seal silicone glue works ok for a while, then seems to ‘shed’ from the aluminum.
Urethane glue is available – but apparently only in a 10-oz Caulk-gun size for $20.
