Need to give some tires back from spider search

i need to return the tires that were lent to me for the search at spider lake. they would not let us in to the trail system with high rollers which were the same tires the lost biker had been using. so i think that sean and his wife brought up a set but i am not certain as things were a bit frantic. so i need some help in getting this rubber back to it’s owners. they are michellin mountain extreme dual compound. thanks folks.
