We have a 2011 Montana which just had all new tires put on. The tires are stamped for 110 # of pressure. It seems high and in talking with other RVers they run around 90#?? Also when the mechanics put the tires on they put smooth tread tires on one side of RV and cross treads on other side, is this correct?
Thanks
 
One thing you want to make sure is your rims are rated for 110 psi it should be stamped on back off rim.
As far as tires sounds like they put two different tires on your rig instead of the same all around
 
What model Montana do you have? It really helps if you provide at least the Year and Model of your Montana in your Signature and Profile.

Depending on your model, the weight of the RV varies and may affect the proper P.S.I. 110 P.S.I. ensures you get the maximum load capacity out of the tires and isn't a bad place to start (assuming your 2011 has the capacity (as stated above)). 90 P.S.I. may be appropriate depending on the RV weight and how much you carry. If you have not weighed the RV then I would err on the side of caution and run 110 P.S.I..

As for the tires. different treads implies different tires. What tires were installed?

Yes, that is our model and year. My question regarding tire tread was shouldn’t the treads match for driver side and passenger side. The tires are configured currently with one style tread on driver side and different style tread on passenger side??
 
One normally installs four tires of the same kind. There is no reason to have different treads. Different treads on one side v. the other is an indicator that different tires were installed. Look at each tire, note the brand, size, and any other pertinent data. Pictures wouldn't hurt. Compare that to your sales receipt. It seems that someone made a mistake and installed different tires.
 
In addition to what Carl said, check the date codes on the tires. You may find that 2 tires are older and the tread style changed even if they are the same brand/size.
