I stopped for fuel yesterday (at $4.40 per gallon) in Needles, CA at a Shell Station at the intersection of I-40 and US 95. A worker at the station tried to sell me new tires for my A-Liner popup. He said I had passenger tires and needed RV tires. I was skeptical since those tires had driven over 10,000 miles with no problem, but I thought I should at least check this out. Maybe this is legitimate or maybe this person is a con artist. If this is a con, then others, beside me, should know about it. Similarly, if using passenger tires on a RV poses a risk, then others should be aware of this safety hazzard. I welcome your input.
