Front end alignment & tires

I have had problems with wear on front tires since we bought our Prism three years ago. I can find no one that can align the front end with the modern alignment equipment. I even took it to Freightliner after I exhausted trying to get it aligned by Mercedes. The reason I am being told is that they cannot get a shot (beam) from the rear tires to the front because the Prism box blocks the beam for alignment. Has anyone else had this problem and can anyone offer advice. It is no fun driving the RV when you know it is not correctly aligned on the front end. That is about the only problem I have had but it is a real nuisance. Also can you tell me what tires you would recommend buying. It came with four season Continental tires that i have been told are not too good and cause a bit of a rough ride. Thank you - Mike Wagoner (832) 274-6542

Camber adjustment was a problem causing wear on my RV. Sprinters come without adjustment bolts, they had to be purchased but were less than $20 each for two required. Mine is not a Prism, Metcedes was able to do the alignment.

Thank you Aggie. Wish Mercedes could help me but the living quarters box hanging over the side of the tires prevents the electronic alignment. I have taken it to many places.

Mike, I had the same problem with my Prism. I found an RV dealer who can align it, but told me it that the alignment is fine, however I should rotate the tires every 5000 miles to avoid running down the sides. I am now diligently rotating the tires as advised.

Bumping this post as I am in the exact same boat with our 2016 Prism 2150LE. Also looking at new tires. 30k on the OEM Vanco 4 Seasons Continentals. I was not very diligent on rotations......The outsides of the front tires are absolutely gone.

I was told by Mercedes that when the build out these vans that the additional weight and it's distribution throws the alignment off thus outer edge tire wear. My local Merc dealer did a great job and rotated the tires to even the wear and installed the camber bolts. So according to my Merc service rep, EVERY Mercedes Sprinter should be aligned as soon as you take delivery to avoid this uneven wear. Said he's seen a lot of them with the same trouble. The RV builders could care less about what it does to the alignment. Glad I caught mine early.

My professional truck wheel/frame alignment shop advised me to set my alignment for max weight NOT nominal. result is I'm at 40K on my Michelins and appear to have 10k to go. IMHO, if these "boxes" are preventing alignment, remove them and get on with it.
Just my humble $0.02//Ed

Wow the original post is quite old, but I’ll chime in.

Rockford is correct, I caught mine with just over 9,500 miles (bought lightly used 2018 Prism 2200 from FL) on it during the trip to CA. It just looked funny sitting there when I stopped long enough during the trip to check it out from afar. By the I could see wear on the outside of the front tires.

Got it home, and began the process. Took it to MBZ local dealer I deal with too take care of Air Bag Recall I saw on Car-Fax, and to rotate & align. My unit is too large for them.

America’s Tire (Discount Tire Outside of CA) for rotation.

Local (small alignment shop) as recommended by MBZ. They didn’t have too elaborate alignment equipment that prohibited the younger generation from completing the job because of the earlier posted Big Box issues, but good enough digital equipment to corrected 1-1/2 degree & 2 degree on the other side camber issues. This corrected all of the (very slight) steering wheel looseness I felt driving it down the road.

Hope this helps others,
Lucas
