Tire Pressures
Okay, I'm probably talking oranges and potatoes here because I have a Class A on a Workhorse chassis. Tires are 245/R 19.5.
Had new tires on it when I bought it. With 36K miles on them, the tread was still about 90% there. Could not balance them. After checking, they were out of round by about 1.5 inches. Sticker by the drivers seat calls out 95psi. Manual calls out 85psi.
Started checking and found that the tire dealer was trying to sell me a tire that had a SPEED rating of 31 mph (B). Load range G.
I ended up with Kellys on the front, Load range G, speed rating (L) 75 mph and Falkens on the back, Load range H, speed rating (M) 81 mph only because they didn't have 4 more Kellys.
You have to check the speed rating as well as the load. A (B) rating is only sufficient for a delivery truck running around town, not highway speed all day.
