ramble2gether Report post Posted November 14, 2016 New to FMCA and the forums, so we wanted to say HI! Also looking to find out if anyone might have any help they can provide on tires for our coach. At this time, we have 5 Goodyear G159 265/75R22.5 (all drive positions and passenger steer) and one Sumitomo 11R22.5 on drivers side steer position and we are looking to get new tires (the youngest of the tires on the coach was made in 2008!!!) but are having issues finding out what Spartan or HR would have put on the coach from the factory or in the showroom. We have seen videos where they have 275/70R22.5, 265/75R22.5, etc, and want to get the RIGHT tires for our rig. Goodyears or Michelins, we have no preference so yet another place we would ask for direction. Thanks for your time Chad and Sarah Share this post Link to post Share on other sites
wolfe10 Report post Posted November 14, 2016 Ramble2Gether, Welcome to the FMCA Forum. By law there will be a GVWR plaque with the OE tire size and recommended PSI (the PSI based on each axle being loaded to GAWR (Gross Axle Weight Rating). This plaque is normally located near the driver's seat, often outboard on the wall. It will also list the OE wheel size. Please post both OE tire size and wheel size and we can help with good, current choices. Share this post Link to post Share on other sites

Our coach came with Goodyear from the factory. We tried Michelin for the second set and noticed a marked improvement in ride quality.

ramble2gether Report post Posted November 16, 2016 Wolfe10- We contacted Spartan to get info on the OE tires that were on our coach, and it turns out that it was delivered to the original owner with Goodyear G159 265/75R22.5s. Goodyear no longer makes the tire, as I'm sure FMCA owners are aware, and the suggestion from Spartan is to go with Goodyear G670RVs in all positions, but that brings a hefty price tag, and although we're aware that pinching pennies is not the best idea when it comes to tires, we would like some guidance on other possible options that will keep us safe and on the road without incident. Thanks in advance for all your help Chad and Sarah Share this post Link to post Share on other sites
wolfe10 Report post Posted November 16, 2016 Many tire manufacturers make the 265/75R22.5. You can also look at Michelin 255/80R22.5 XZE or XRV through the FMCA Michelin Advantage Program. The 255/80 if virtually identical to other manufacturer's 265/75. Share this post Link to post Share on other sites
wildebill308 Report post Posted November 16, 2016 Chad welcome to the forum. Like Brett, I see no reason you couldn't run a 275/70 22.5 X2A2 Energy from Michelin. One other tire is the 255/80 R22.5 XRV in the right load range. Here is a tool that you can use to compare size. https://tiresize.com/comparison/ Bill Share this post Link to post Share on other sites
ramble2gether Report post Posted November 16, 2016 Any thoughts on positives or negatives of going with an import like Toyo? Chad and Sarah Share this post Link to post Share on other sites
manholt Report post Posted November 17, 2016 Chad. Have never heard a negative and know folks that have them. I run NITTO'S on my Jeep, Import and like them better than Baja's...2nd set. Just make sure they fit your rims and have the same carry capacity...there are some posts, under tires..2014 & 15 or you can enter Toyo under Search at top of main page.

abyrd Report post Posted November 17, 2016 (edited) I have KUMHO on my MH and am please with their performance, have run them for three years 15,000 miles. Jim Edited November 17, 2016 by abyrd Share this post Link to post Share on other sites
manholt Report post Posted November 17, 2016 Jim, that's a brand that I know nothing about. I currently run Michelins, replaced them in 8/14 by Superior Tire in Oregon, no tax, got to love that ! I carry a lot more weight than you do and drive an avg of 14, 000 miles a year! Back in the 70's I used Cooper tires, and in the 80's it was 19,5" Kelly's...ever since that I've had 22.5's I have run Michelins...mostly because of availability! That all started to change in 2014 about the time I got my last set of 8...I have 315x80x22.5 on steering and 295's on rest. I probably wont have to do that again, as I'm fondly looking at Marathon and Newell. That's why you see old geezers rolling down the road in high dollar sports cars...it's a need, for one more time, then we hang up the keys! Carl Share this post Link to post Share on other sites
ramble2gether Report post Posted November 23, 2016 Thank you everyone for your input. We do have another question for the group though. We are hearing a broad spectrum of opinion on this issue and wanted to ask other FMCA members for theirs. Back to the original post, our G159s are in amazing condition, however, the dates on them are a bit of a concern, with the youngest tires having a DOT date of 2008! Tire centers are saying with a 2008 date they won't even inspect them for us and are warning that we risk our safety and potential major damage every time we are on the road. We see no sidewall disintegration and the tires, like I said, look to be in incredible condition. So the question is, what would other members do? thoughts? suggestions? Do we have time before replacing them? Thanks in advance, Chad and Sarah Share this post Link to post Share on other sites

There is no absolute that they will pose any threat in any way, but there there is no absolute that they will not. Probability is much against any favorability that they will not. IMHO, I would make swings out of them, and spring for new ones, just for my own comfort of mind, if not for the safety of others. A blowout could be lethal!

wolfe10 Report post Posted November 23, 2016 At that age, the likelihood of failure is much higher than with new tires. Not sure you want a statistical analysis-- they just need to be replaced. Share this post Link to post Share on other sites
five Report post Posted November 24, 2016 What Brett said. I had a set of GYs on my former coach, they were dated 08 and the RF blew in May 2015. Share this post Link to post Share on other sites
wildebill308 Report post Posted November 24, 2016 Welcome to the forum Chad and Happy Thanksgiving. The problem with tires is it is what you can't see. Here are some good reference links. The first one talks about service life of tires. In the first bulletin they talk about having your tires inspected by a dealer at 5 years and some where I have the bulletin that states after 5 they should be dismounted and inspected https://www.michelinb2b.com/wps/b2bcontent/PDF/3_TB_Service_Life_RV_Motorhome.pdf http://www.michelinrvtires.com/assets/pdf/MotorHomeTireArticle.pdf http://www.michelinrvtires.com/reference-materials/videos/ Look at the FMCA Michelin plan. You can also buy tires for your other cars with it to. I just saved $172.00 on the tires for my toad. We are waiting to hear about a plan with Continental to be announced, soon I hope. I know the cost is high to replace your tires but one blow out can cost you much more. Bill Share this post Link to post Share on other sites
jrock Report post Posted November 24, 2016 Chad listen to these guys they have put a lot of miles behind them. When we got our coach tires looked like new all shined up with tire dressing I didn't look at date and after hearing some of the stories went and looked they were the original tires 12 years old don't let looks fool you old tires are time bombs. Had 6 new Michelins installed and ride was so much better it told me that they must have been getting stif from age and I was headed for a disaster . Is stinks to put the monies out at first but after you do the first few miles will make you know it was a good investment. Share this post Link to post Share on other sites
ramble2gether Report post Posted November 25, 2016 Thanks, Jrock, we are definitely planning on listening to folks that have been RVing for many miles, and in the process of getting tire prices and info together. And thank you Bill for the links. Now we come to another query. Spoke with a local rep from Goodyear and he was talking about the fact that certain tires that we are looking at don't come in the OE size. I know in the beginning of this thread we talked about going from OE size of 265/75R22.5 to 275/70R22.5 or 255/80R22.5, but the rep made a suggestion that he says will be a smoother ride and a more common tire size for today of 295/70R22.5 and that only adds 1/2" to the overall diameter of the tires (after using the link Bill provided up top, https://tiresize.com/comparison/ , we see that it adds .7" to the diameter.) Can anyone provide any thoughts on this suggestion? Thanks Chad and Sarah Share this post Link to post Share on other sites
wolfe10 Report post Posted November 25, 2016 Chad, Can't imaging going from a 255/80R22.5 or 265/75R22.5 to a 295/70R22.5. Doubt that you wheels are even wide enough for that large a jump-- VERIFY. And, doubt you will get a smoother ride from a tire with a shorter sidewall (less sidewall to absorb bumps). Share this post Link to post Share on other sites
wildebill308 Report post Posted November 25, 2016 Like Brett said I would verify the rim with will work. The dealer should be able to do that. As to ride there are many components beside size of the side wall. The composition of the material and rubber make more difference. I am thinking these will be a little higher rated(weight wise) and you may be able to run less air pressure and improve the ride. You will need to weigh your coach to do that. New tires will give you a smoother ride any way. Bill Share this post Link to post Share on other sites
