A tire on my Volvo was losing air every day. Another shop claimed that the rim was bent and/or corroded and that I needed at least one new rim - probably more than one. ALL TECH investigated the issue and pointed out that the previous mechanic had damaged my tire when they removed it, then attempted to "glue" the damage tire thus causing it to completely lose air within eight hours or so. Semir told me I did not need new rims, only NOW a new tire. That cured the problem! Thank you Semir!
