Gary Dymond quotes some tire prices and forgot to change the $ sign to Pesos. At least I hope so!! This knocks them down to around 150 and 244 US dollars. ,pricy, yes ,but not out of line with what the supposedly top line tires cost up in anglo-land at the fancy dealerships, plus installation,balance,tax.The trick is to keep an eye on your tire wear and head to one of the larger centers before you are in desperate need . Guadalajara,Cd.Mexico and Monterrey are the surest bets for immediately finding what you want because they have the national h.q. of most of the parts-,tires-, and motorcycle importers. Do check out availability of tires and other parts at any of the ubiquitous Tiendas de repuestos y motopartes, i.e. private motorcycle parts and accesory shops, as well as the branded dealerships. If you are in a bind they can order in any tire you need and you can enjoy the wait of one or two days by exploring the local area or be a pedestrian in town .Last year the battery on my KLR died in Colima and none of the dealers had the correct one , but the Kawasaki shop put me in contact with such a parts store which did have it in stock. The Kaw shop put it on the charger overnight for free , great people.If my tires upon leaving home appear to have enough life left in them to do even half the trip I do not bother changing them , I have never been disappointed trying to find replacements en route in Mexico or Central America or USA.
