I got some rather old Shelby Cal 500's for the back of my truck. Fitted some new tyres, but unfortunately they aren't quite air tight and go flat over a fortnight or so.
Checked the seal around the rim and the valve and all is ok there, so I've figured that the rims are porous. As I want to park it up in the garage for most of the winter, I'd like to sort it out so's not to have to keep blowing tyres up every time I want to take it out.
So, does anyone recommend a wheel sealer that I can pop the tyres off and use, or would I be better with tubes, bearing in mind that they are 265's on 8 1/2 rims?
