I recently retrieved 4 tires out of my shed to find two of them deflated. When inflating them, I could hear hissing-through the sidewalls!! They were rotted and cracked. When I put these (used one winter) studded snows away about 9 years ago, they were inflated and treated with either Armorall or spray silicon. The shed is open-front so they were placed against the back wall,out of direct sunlight. Ironically, my occasionly driven '90 Nissan truck(58K miles) has it's ORIGINAL Firestones. Yes, their sidewalls are cracked, but they don't leak and have inspectable tread. The truck is kept in a carport. Over the years, I may have once or twice sprayed the tires. Every spring, I religiously wash under the truck and spray all the rubber-like parts(CV boots, engine and body mounts, etc., which would be a hassle to replace) with either Armorall or spray silicon. Both are preservatives, right? Well, maybe not. I seem to remember from the Michelin website that they do not recommend putting anything on their tires. I don't care about making these parts pretty (who said tires were supposed to be shiny, anyway?) I just want these parts to last. Have I been wasting my time and money under my truck with a spray can - or worse, actually harming these rubber components?
