2010 or The 2011 Rockwood 8314ss

We were at a local rv show at Reicharts Camping Center yesterday in Hanover PA, and I saw where someone bought a new 8314ss I don't know if it was a 2010 or 2011 but I had looked at the tires on it and noticed that it came with ST225's, now this unit did not have the bedroom slide out. My camper is the same model but it is an 06 and mine came with ST205's. My question is this a standard size tire now on this model?
A year after I had my camper I put ST225's on It.

Mine is a 2010 8317ss, and it came with ST225's.

Not only have the tires been upgraded, the axles have also been upgraded to 4000 lb capacity. The brakes and hubs remain as before.
