We understand that this is a big inconvenience for our buyers, however, this is ABSOLUTELY out of our control. For example, you can receive 3 tires in one day and the 4th one the next day or the day after, or one tire in one day and the second one day after. Tracking information can be checked by logging on to the courier website with the master tracking number you will receive via email. Besides, I think that most people assume that the 315s are the modern equivalent to the 12R22.5 size, but apparently not in every way.Attention! Due to the size of the tires, Packages might be SEPARATED in the courier facility and not be DELIVERED on the SAME DAY, even though we do ship them together. He ran a fleet of commercial buses, and I'm sure that he just had his guys install what they had on hand and didn't even look closely at the specs. My suspicion is that the previous owner put on the 315s because that was what he had on hand. Guess GM put the 12R22.5 tires on there for a reason. This would hopefully eliminate the problem with the 315s rubbing the air bags on a hard turn, since they are about 1/2" narrower than the 315s. While my current tires have a little life in them, I'm seriously leaning towards swapping them all for the Toyo 12R22.5 at the start of the spring driving season. ![]() What I'm referring to is the tires being able to slightly rub on the outside of the air bag when the steering wheel is turned to the extreme. ![]() This can be done without hooking up a pressure gauge?Īnd to correct what I wrote earlier - I'm not currently able to hit the stops when turning. This is really important, as if steering box is able to drive all the way to the physical stop, PSI in the steering sector goes way up and very easily blows the seals.Īn easy job once you understand the concept and have a second person to turn the steering wheel stop to stop. ![]() Then, (actually both done a little bit at a time) the plungers (tiny external screws) are adjusted such that there is a 1/8" gap between axle and stop. Yes, it is CRITICAL to adjust both the physical stops on the knuckles (adjust such that there IS clearance between tires and suspension/body components). This info for Sheppard steering box- let us know what you have: My guess is that the upper tire in this chart is the one that I'd want. The size I need apparently come in two variants, the width being the difference. The Toyo M170 have been used on other coaches, and the results appear to be good. The other thing that I've discovered is that there are adjustable stops on the front axle, and it should be very easy to adjust them so that the 315s on the coach now can't contact the air bags. Maybe I just need to have them shaved a touch to get them where they need to be. One thing that occurs to me is that the tread depth is much deeper on modern tires, and I think that this is what makes the rpm count off a little on modern 12R22.5 tires. I don't think that there is a really exact match for the tires that were on the coach from the factory. None of them are exactly at 495 rpm either, with most being about 500. I've looked at the 295/80R22.5 tires in a number of brands. I been running the Michelin XL Energy Z since 2014 and love them compare to the One years (Goodyear) that was on the coach. !/info/x-line-energy-z-coachĪnyone have any experience with this tire? Since some of the larger Class A coaches out there are running the 315/80R22.5 size tires, I'm hoping that at least a few people can let me know what they think of these tires. One tire I'm looking at is the Michelin X Line Energy Z. Not sure if they are better, about the same, or a step down. So, I looked at the Michelin tires available, and with the FMCA discount they would end up costing about the same as the Firestones. The tire dealer I'm hoping to work with is recommending Michelin, mainly I think because that is their main line and the Firestones will need to be ordered in. My initial thought was to replace them with a new set of the same. We've been happy with them, and other than the tires being seven years old there is absolutely nothing wrong with them. Right now we're running Firestone FS 400 in 315/80R22.5 size. I'm starting the search for new tires, hoping to get them installed in early spring.
