A number of posts mention Costco as a good place to buy the tires and I have had great luck with them in the past. I called my local Costco and they told me they only carry up to 19".
Has anyone been able to get 20" tires from Costco? Special order?
If that route is unavailable, any other suggestions? I have bought tires from Discount Tire in the past, but have not been particularly happy with them.
I am in San Diego.
Thanks for any help.
