    Thanks everyone.. That helps me . I think I might go with the 235/80R 16 Goodyear Endurance I now have 225/75R 15 on my 2016 Reflection and am trying to get my act together to make the purchase and do the up grade. I also have 6 lugs 6" rims. I need to get new wheels and then should be able to make my move. Thanks again !
    I went to Granddesign with these questions and they could not give me this information. Don't know why but was very surprised they couldn't help.. Glad I have the forum. I omitted any names.
    Our current units are using 16” wheel. I do not know if they will fit on your unit as I don’t have anything that cross references wheels.

    OK, can you tell me what size is being installed on the new 303 rls ? They have 16" tires and rims. Also I thought you could tell me if I can upgrade to the 16" tires as you have my vin number and can check that it will work with the 2016 Reflection I have ?

    What you have to be careful of is clearance above the tire on the bottom of the RV as the 16" tire/wheel combo will be taller than your 15" set up.
    If you are just looking at replacing the tires there are 15" E range tires available.

    Brian - in this thread post #23 he referenced having the 2" rise to the frame. He s/b GTG.

    https://www.mygrandrv.com/fo...033#post225033

    The addition of the 2" square channel was implemented by GDRV in 2016 on the 303 (and some other models possibly as I recall) to help level the trailer when being towed by the newer generation higher 2500/3500/etc. trucks and allow for clearance for the (at the time optional) 16" tires. 16" are now std. and have been for a couple or so years.

    Rob and I had the 2" tubes added by the GDRV factory service center. I also upgraded to 6K axles/16" tires and wheels. I believe Rob is running 15" yet but towing with his 1500 truck, I think he is towing pretty level.

    Dan, if you have a 2014 and have the 2" tube added to frame and upgraded to 16" wheels and tires then my Reflection 2016 with the 2" tube on the frame should be ok for the 16" upgrade. I am planning to stay with the original axles. With my setup I am pretty level I would imaging I would stay pretty close after going to 6"". Thanks for the information. I really would like Grand Design to give me some guidance. Like is the 2" addition the only change to allow 16" rims and tires. I am sure someone there knows. Especially if Grand Design chanced the Reflections to 16 " to help with reducing blowouts. That's a safety issue. Sure wish they would help . I know they didn't just install 16 " rims and tires for the fun of it !! The 16" Goodyear tires are rated 3420lbs and have a diameter of 30.8 I would think they will work. Thanks for your help. Duke !
