alright, i work at a gas station with a garage, theres a pile of tires out back which i can give away,
but as always for something free there is a downside, the condition of the tires are unknown, i wont give away any that have visible issues but i cant gurantee they will all hold air or last longer than a run or two, most of them have been chucked due to very uneven or excessive wear
or have a puncture and the owner just decided to replace other than patching a tire thats at the end of its life
but for tires with punctures in them you can pick up a 5 dollar plug kit that will fill 10 punctures (just cut the strips in half they are rediculously long)
so shoot me an ideal size and i will see what i can do for you
ill try to pair tires up but if your okay with mismatches let me know
