I upgraded to 7000# axles and 'G' tires. Now I think I should have stayed with the 6000# axles and 'E' tires and then upgraded to Michelin 'E' tires after it got here. The new BC came in with Freestar tires so the $1500 upgrade still has crappy tires on it. Could have done nothing and upgraded 6000# axles to new tires for that price. Or will I be surprised and find out that the Chinese tires are now good. I talked to tire dealer about a trade and he wouldn't take them at any price. Said he had a lot of people coming in with Freestar with separations. New GY 614's about $250 a tire mounted. Need to factor in $1000 for whatever Heartland you get if it comes in with Chinese tires. Hmmm, if they cut corners on tires where else did they cut? This doesn't just apply to Heartland but any trailer manufacturer.
