if thats it it should be a easy fix. just gota take off the tireI ran into this problem with my Razr2s. It turned out to be the rim. I got ITP T-9 pros and the rim itself was leaking. To make a rim they have to weld 2 pieces together and it was leaking around the weld. I couldnt figure out why my tire would leak 1lb of air a day and the rim was the problem. You might want to check that out. Hope that helps.
I am a Brit and I would never get an MG Midget.Baxter,
Upon reading you recommendations for the tire leak, I was taken back to my days of restoring a 1975 MG Midget. Your quote "Let the air out of the tyre" reminded me of all the bloody knuckles and profane language. Between that and the bonnet, sparking plugs, Lucas electrics and the boot I guess I am just a hopless British car romantic.:lol:
Sorry, I am off topic.
Baxter,I am a Brit and I would never get an MG Midget.
Best bet get 5 gallon of petrol and a box of matches.
