This is a regional steer tire. I thought Sean at one time recommended long haul steers and regional drives, but I couldn't find the message with a search.
Brian, I can't say anything specifically about Roadmaster brand, but I can confirm that I recommend regional tires all the way around for the kind of use our coaches see. You and I talked about this once before:http://www.busconversions.com/bbs/index.php?topic=20174.msg220513#msg220513
"Long haul" or "Linehaul" tires are meant for service that includes 95% or greater non-stop Interstate driving, with the only "local" driving being at the beginning and end of each long-haul run, between the terminal and the freeway. On the other end of the scale, "Local delivery" and the similar transit coach tires are optimized for around-town driving that is mostly stop-and-go, backing in to docks, plenty of turns (some of which will involve hitting curbs), etc.
"Regional" tires are meant for a mix of freeway driving and local roads, which is what most RVs will also see. Very few people get in their coach, drive directly to the Interstate, then go 2000 miles before getting off the freeway to drive ten miles to the campground. To put the term "regional" in perspective, these are interstate carriers (in all but the largest states) whose service territory includes a handful of neighboring states, or they are LTL carriers who make several stops with the same truck. A typical regional route may be a few hundred miles, whereas a typical longhaul run can be a thousand or more.
Long haul tires will generally deliver slightly better fuel mileage, but at the expense of sidewall and tread characteristics with greater durability for non-freeway driving.
It appears they might even be made in the USA still.
You can not tell in what country a tire is made from the brand name. All the "Japanese" (Bridgestone/Firestone, Yokohama, Continental, etc.) and even those "French" brands (Michelin/ BF Goodrich) have truck tire plants in the US, and the lone major US-based brand (Goodyear) has plants overseas. The only way to know is to actually look at the code on the tire itself. I described how to do this in this post:http://www.busconversions.com/bbs/index.php?topic=11274.msg118361#msg118361
