Ok. I am ready for all the input. I had a winnebago 38G and I have inherited my parents 2007 Monaco Knight 38PDQ. My parents thought they would travel the country in style, then they discovered it was much better taking his plane and being in hotels. That aside, I was offered there motor home this year. My main reason for posting here is the variety of input of tire related questions that I have, and also I have heard. the tires on the unit are Goodyear 275/70R22.5 and the coach only has 5100 miles on it. It has been stored in there airport hanger on the levelers when parked for the time it was stationary. I have heard all the the horror stories from all posts about the date codes on the tires, tires blowing out, running off bridges, running over little old ladies, etc. My problem is that I dont know how to judge the tires on the unit versus the date codes. Of course you call Goodyear and they give you the company line. So I decided to take it to several truck tire stores to get there input. Three out of three told me tires were better than normal. Two out of three told me to have the front end checked since the coach mfgs. usually dont have the alignment right. So, here I am. I would like input from you guys on the tires. Keep in mind the date codes are middle of the year 2006 and the related storage listed above.Thanks,Bert

I have the same coach but a 2005. It is a great RV. You do need to change the tires. RV tires do not get enough use so the oils in the tires do not get distributed in the rubber and all the setting causes a lot of stress on them. I know it's hard to throw away all that trad but it the nature of the beast unless you are using it all the time. Yes you do need to check the alignment anytime you get tires but the chassis is usually done before they build on it and add the weight so yes it usually needs it when you first get it. I am about to get my 3rd set of tires this March. I use the Goodyears and have had great service with no problems. Take on here what you read with a grain of salt. Do you homework and fix your RV from a experienced source not recommendations from a lot of people you don't know whom are guessing most of the time. This is a great place to get ideas but it is a fraction of all the RV people on the road today.

Welcome to the forums and that's a nice MH. If I lived near you in TX I'd say replace all 6 so I could buy them and use them on one of my trucks. Unfortunately a 275/70 is not a normal truck tire size so selling them for $200+ each is not likely. Since you know the history and stored inside with some weight off the tires I'd replace the front two tires with Toyo or Hankook. Here's 61 posts on Goodyear and rivering. As you found out, truck tire places say they are fine while most on here will say replace all of them. I would carry one of the replaced front tires unmounted on the roof wrapped in alum foil and plastic wrap as I actually had a truck tire place laugh at me when I needed a 275/70. Here is a previous post on carry spare on the roof.We are into weighing our MHs when loaded up and adjusting the tire pressures for the weight. My educated guess is you will need 105 in the fronts and 95 in the rear tires. While 5100 miles is not enough to tell about the alignment by looking at the front tires, you can check the toe in by measuring between the two same spots on the inside of the tires (front/back) and you want 1/8" toe in.

If it were mine, I'd replace all the tires. They are 7 years old and that is my limit on RV tires. Goodyear G670's have reputation for 'rivering' on the front. I replaced my G670's on my previous coach with Hankook AH-12's in 275/70/22.5 and they were really nice tires with a great ride and handling. As noted, I would keep one of the existing tires as a spare if you have room to carry it somewhere in the coach. 275/70 is usually a size that has to be ordered.

If you have any intention of keeping the tires, I would have them inspected by a heavy duty tire company by taking them off of the rims. That will give you piece of mind if they pass their visual test by looking inside the tire. Personally, I wouldn't prefer Goodyear's as I had friends have trouble with them but yours are like new. That's why I would have them looked over really good and use them maybe for another year or so. I have ordered new Michelin's using the FMCA program that should arrive at the end of this month replacing my current Michelin's with 57,700 miles. I'm just leaning on the 'safe' side replacing them at 7 yrs. as my date codes run from the 20th-42nd week of 2006.Good luck and let us know what you decide.MM.

I'm replacing my 7 year old tires this year. But not putting the Michelin or Goodrear tires on it!
