How many times did you align the vehicle during this 35K miles?
Tire Tech Information - Alignment average alignment time frame i think is 10K or 1 year which no one does but i would do one around 15 to 20K or every other year but as in this article explains anytime you think something might have been damadged as hitting curbs, tires and alignment need checked. My wife called me one night and said HELP!! i had a flat and being about 1/2 mile from home i went to help her and she did not have 1 flat she had 2 flats, also a curb jumped in front of her and blew out both rt hand tires and ruined both rims and rt front strut bent. tires need an alignment if you want the best tread wear possible, 30 or 35K on a set of tires and no alignment will show wear depending on front end measurments and what has worn.
So which tire Toyo makes were you using on your Rav4, size? type? lotta info not given ? little carrot about being oversized did not help anyone much or was that all we were ever going to hear?
