Ron,

My guess is that you voided your warranty by using those tubes.

Joking/jibing aside, do you store (park at home) your MGA in a garage? I ask because my concern about my 7 year old Cooper LT radials (with tubes) is their age. I've read that people should check date codes and not buy-or-use(?) tires that are more than 6-to-10(?) years old.

" . . . The danger of old tires has been known since at least September 2003 when the British-based Tyre Industry Council issued an unprecedented warning that previously unused tires should not be sold if they were more than 6 years old, and that all tires should be replaced 10 years after their manufacture.

It is curious that European and Japanese automobile manufacturers warn of this danger but NOT U.S. tire manufacturers. For example the Volkswagen manual states “WARNING – old tires can fail in use, causing loss of vehicle control and personal injury. Replace tires after 6 years regardless of tread wear.” . . . ".
