I had 9R22.5 on the Sahara but was having a hard time finding them. The manufacturer also recommended 25570R22.5 as well. I bought a set of 6 Yokohama RY023 tires for $2500. These are 16 ply H rated tires. The only issue is the smaller diameter makes my speedo read high. Here's a thread on the 661s. When you change tire sizes you can get a CAT or Cummins to reset the "Pulse" rate for your speedometer to read accurately. Takes under 15 minutes and for me was no charge. Service manager did it and called the others over for a teaching moment.Re: Monaco manual source?IRV2 Monaco Owners Thread It may be of help AlsoRe: Breakdown InformationTwo Different Motorhomes: First New Year's Day 1999 in the Lower Keys went to start and air had gotten into fuel delivery system when we tried to start in campground. Service done Jan 2 through RV Road Help Sign and Drive Two Front tire catastrofic tire failures: First North of Tampa 32000 miles on tire no spare and ruined Al Rim. Olsen Truck Tire whom we had purchased six tires from refused to do road service because we did not have corporate account. Olin Mott Tires brought tire and found rim and were very helpful. Tire maker was very generous in adjustment and damages caused to coach. Was (not a Michelin tire) and Olson Firestone are never getting any more of our business (think now Service Plus or something like that now) Olin Mott has and will continue to get our business. Second Tire East of Jacksoville, wheel was usuable but scared again no new tire dealer was as nice as Olin Mott, Tampa and FHP called provider who required cash and sold us a used square tire for $100 plus service. After promising to refund tire cost if I left it at a new tire dealer and after writing the FHP (a month later) he sent me a money order and a thankyou note expressing thanks for me getting the FHP to remind him to send me a refund. Again the tire maker (who we cannot name because we agreed not to tell the name as part of settlement) stood up and took care of the damages. Sorry not in specific order requested but I do not care what grade you give me.Re: Breakdown InformationMost diesel engine breakdowns are probably fuel delivery problems or elictrical. Most gas engine breaksowns are overheating including vporlock or electrical. Biggest cause for breakdown is flat tires.Re: Anyone make a mistake buying first MH ?We have backpacked, had a pop up, a class C, two class A gas and two class A diesel. Our current 40' Slide would have been a mistake 25 years ago because we were not ready for it then but it is ideal for us now. A mistake would be buying a motor home that does not fit your lifestyle or budget. We used to do a lot of state parks and needed a smaller coach. Now we are going to a bit more upscale places and my wife is a 50amp girl.
