I will probably use J&P cycles.One thing I noticed before getting my Wide Glide was that owners complained of having to replace fr.tires more frequently.21in.and less contact is why,I imagine.So I looked em up before getting the bike they are right around $100 or less.Free shipping.I have seen some complaints on date of manufacture,but they were replaced by said co.Sometimes dealer has a special,there are more and more indy's popping up around here,too.As far as actually changing it.But the tire alone,J&P has had the best price I can find so far.
