Hi all,

I had a heck of a time finding my way back to this post string.  Anyway, I have done the axel flip and bought new brackets for the fifth wheel hitch lower it about 2 inches.  The picture is before the installation of the brackets and now I'm pretty close to level.  I currently have ST225/75R15 tires that need to be replaced.  They have dry rot damage and was wondering if there is a larger tire that would fit on the 15" rims?  I'm only about 1-2 inches from being completely level.  Also, what brand is best at a reasonable cost?

To stay with 15" rims,  larger tires come from wider tires i.e. ST225 --> 235 or 245 tires  and / or from higher profile  i.e. /75R15 -->/80R15.  Make sure there is room for either, including suspension travel.  Make sure ANY tire has the load rating to handle your camper. 

The 225/75 15 tire is 28.87 inch diameter.  A 245/75 15 is  29.46 inch diameter.  A 245/80 15 is 30.43 inch diameter. 

I can calculate 16" diameters if you choose to go that way.  Remember only of that diameter is below the axles and will raise the camper only of the increase.

It's not a dumb question if you do not know the answer.

Thank you Grashley, that is great info going forward.  You all are an awesome group or folks! 

We are headed out this coming week for the maiden voyage, so I had new tires put on today.  I went with the 225/75R15's, but the tire shop recommended 10 ply (instead of 8) since I am loading 2-3 touring motorcycles in it, and with a L speed rating (75 mph) since the highways out have a 75 mph speed limit.  Not that I will run at that speed, but I figure at max pressure they will not run as hot with them being over rated. 

I was trying to get completely level, but I think I am close enough to not have issues with running the propane frig while traveling.  Guess I will find out.  If not I will look at moving to the 245/80R15 you mentioned and/or go to 16" rims.  Where I am now the stabilizers are good and the steps aren't too high, so hopefully all will be good.

Another question, if you look at the picture I posted earlier the spot light mounts and the door window framing is yellowing.  Question is, is there anything I can do to get them white again other than replacing or painting the plastic?  Was hoping there was a treatment or chemical that would do it?  It sticks out to me since everything else looks fine.

CybexRV,
Don't know the answer to your question but thought I should suggest that you start a new post so that you get a much larger audience. I think you'll have a better chance of getting your question answered.

Don't know of any product that will change the yellowing plastic, likely due to UV rays over time.  I would paint them with paint special designed for plastic.

Also as far as running the fridge while moving.  Run the fridge at home to cool everything down before you leave, down to about 34 degrees.   I'll freeze a dozen or more 16.9 oz.water bottles, before hand, and place them through out the fridge and freezer.  When they thaw you can drink the water.  That will keep the fridge cold for 6 to 8 hour of travel.  Don't open the fridge if not necessary.  Use a small cooler for drinks and food and snacks while traveling. Think about it. a refrigerator is insulated as good if not better then a cooler.   Running the fridge while it's not level creates unnecessary heat in the cooling unit.

Those 10 ply will serve you well.  As you said, keep the speed down.  You have a safety factor based on lower than rated speed AND less than max load.  Wise move!

As for the yellow, UV will discolor the plastic over time.  The only fix is to paint or replace.
