Wallace never did have much of an internet presence. In fact, if you have dealt with Wallace in person, he was still using the old "kuchunk-chunk" machine to process your credit card. End of the day, his prices are pretty much in the ballpark with the others, so unless you are buying from him in person at one of the conventions, you are likely better off buying from one of the places like summit tire or simple tire who offer the free shipping.
I see his facebook page is still there, with the last post from a customer just 4 months ago.
Oooops, just spotted on another site that it is reported that Wallace Wade tire shop has closed.
