Long story, cut short. If you're ever in Nacogdoches, TX & need a tire fixed, repaired or trouble shot-pls call El Indio Tires. It's a small (emphasis on small !!) minority owned & operated tire shop in town, about 2 miles from the main drag - that's Hwy 59 to & from Houston. They have a mobile repair truck too but we drove into town to their shop. They could've taken me for a real ride but were so fast & fair, I had to write. They removed a tire that kept losing air, & put on the spare. They found that the value stem was bad and that was the cause of my slow leak. Chg'ed the valve stem and did all this in about 10 minutes. Cost-$10. Great folks. Muchas gracias, El Indio. I hope some other vets give you their business too.
