Re: Tire Size Reply #2 – September 02, 2019, 12:35:44 am Look at 255/80/22.5 or a 255/70/22.5. Rim width is important. Quote Selected 1 Likes
Re: Tire Size Reply #3 – September 02, 2019, 01:43:10 am 255/80R22.5 is a good substitution/slight upgrade. OK on 6.75" or 7.5" wheels.Many of us have upgraded from 9R22.5 to the Michelin 255's-- so this is from experience, not just a chart. Quote Selected 1 Likes
Re: Tire Size Reply #4 – September 02, 2019, 09:32:46 pm I replaced our 9R22.5's with 265/75R22.5's. Quote Selected
Re: Tire Size Reply #5 – September 03, 2019, 12:05:37 pm Are you having trouble finding the 9R ? I like that size for the early light coaches. Quote Selected
Re: Tire Size Reply #6 – September 03, 2019, 10:29:27 pm Yep 9R's are getting hard to find and the dealers want a bunch for them. Quote Selected
Re: Tire Size Reply #7 – September 04, 2019, 02:27:25 am Probably not going to get any better, as manfactures trim down the number of tire sizes available at a reasonable cost.. ideal vs economics gets skewed pretty quickly, and then throw in again the local available factor. Quote Selected
Re: Tire Size Reply #9 – September 04, 2019, 10:41:44 am I don't understand why the 9R size is stiil around. Does it offer any advantages over the newer metric size? Quote Selected
Re: Tire Size Reply #10 – September 04, 2019, 10:47:53 am I believe it was one of the first radial truck size . Many early trucks and heavy RV OE size, It is about 80% tall/39in +-, and narrow for the 6.5- 8 in wheels. Perfect for my Bus. Quote Selected

Re: Tire Size Reply #12 – September 04, 2019, 01:10:19 pm Supply. No body makes the 255/80/22.5 Michelin? Quote Selected
Re: Tire Size Reply #13 – September 04, 2019, 10:17:06 pm Available, available, available. If you have a roadside tire issue your not going to be able to wait for someone to source a tire, you are getting towed to a safe place, vs a tire service doing a roadside swap. If you have a place to store a spare it's a different story. Or you may or may not be able to limp in with a different size. Optimum vs compromise, your roll of the dice. Quote Selected 1 Likes
