i have a 2008 base model trailblazer... i wanna put bigger tires on it... like an all purpose tire... without having to lift it or anything becuz im not into that... how big of a tire can u put without rubbing or causing any damage... and how big of a rim would i need? i heard the fuel lines run next to the tires and it will damage them if i put bigger tires on.. is this true?
