. Occasionally the cheap tyre places will have old stock, which is why they are cheap...
No that's false.....When there is odd sized tyres, they tend to sit around for longer than more common sizes....These tyres that aren't so common, get sold to ANY tyre store from the wholesaler if a customer is sold on them....Sometimes they are on sold cheaper to the store due to age and it's UPTO the tyre store whether they pass on the saving to the customer.....Some tyre stores mention to the customer that they are older stock, hence the cheaper price and they might even mention how long to expect out of them in terms of years....
Another reason tyres might get discounted is pattern run out (like model run outs on cars) or the wholesaler is over stocked with particular sizes (also like particular model cars).
