New Cedar Creek tires

For one thing on your 2006 Cedar creek your rims are only rated for 80 P.S.I. most newer big 5er's about 2011 or so on rims are rated for 110 P.S.I tires,on my 2015 Montana 5er I have Geostar G574 14 ply G rated LT tires 235/85r16 rated at 3750 lbs per tire and a speed rating of 80MPH(not that I would ever go that fast) but stock they came with E rated ST Trailer Kings rated at 3400lbs that are just not the right tool for the job on a heavy 5er, Montana and others brands have a option for Goodyear G rated LT G614's but on my 2012 trade in I already had Geostar G574's and had them put them on the new 2015 and the difference is amazing the G rated LT's I bought do not Sag like the lame stock E rated ST's and after 10K miles on them on all kinds of rotten roads around the US not one problem do yourself a favor and get rims that will handle 110PSI Tires and get G rated LT Goodyear G614's or Saliun's or like my Geostar G574's and RELAX!!!!!
