Michelin x line energy z 315 80r22 511/8/2023 ![]() UPDATE: Looks like the turning stops are adjustable, and it should be possible to adjust to prevent this from happening in the future, removing it as a problem. But, I suppose that this is reason enough to go back to the 12R22.5 tires. At this time I only see that they've touched the dirt layer, as there is no visible damage to the rubber. Obviously on full turn the wider 315s are causing a problem. In looking at the bus more closely, I do see that at some time the edge of the tires have touched the air bags in the front. There are not nearly as many options, which is maybe why people are running the 315s instead. Oh, and they turn 490 revs/mile, which is pretty darned close to the GM spec'd 495 on your coach.įollowing some of the suggestions, I've been looking to see what tires are available in the 12R22.5 size. I've only got about 100 miles on the Toyos at this point, but I'm very happy with the ride, plus they're very quiet on the different freeway surfaces in my area. This would work out to about $3975 for your 4108, if you went for the same tire. was $5300 out the door, which was $940 less than Michelins on the FMCA program. Thus, after three days of pouring over website after website and review after review, I ended up with eight 12R22.5 LR H Toyo (Japanese) M170s from our local Les Schwab store (a company that has over 400 stores on the West Coast.) Mounted, balanced, new stems, taxes, etc. Continental also didn't have a dealer nearby, so they were scratched. Another busnut suggested I consider Sailun tires (which I'd never heard of, found out they're a Chinese product), but they don't have a dealer w/in 250 miles of me, so they were out. ![]() I looked into the FMCA's Michelin program, looking at both the Michelins and the Continentals. This tire will fit on an 8.25" rim, per the T&RA specs. The stock OEM tire on your 4108, as with our XL, is a 12R22.5, Load Range H. All eight of the Alcoas on the Prevost were 8.25", so the 315s were out. ![]() ![]() The Tire and Rim Association does not recommend installing 315/80R22.5s on rims that are less than 9" wide. Turned out the front two and the four drive tires were all 12 years old, and the tags (Firestones, very, very badly cracked) were 16 years old! Scary.Īnyway, after much research, discovered several things: We lost a tire on our "new to us" Prevost about three weeks ago, inside dual. Not sure how that will affect performance, and since I'm already feeling that the bus is short on low-end power I don't want to do anything to make it worse. The other tire I'm considering is a Conti Coach HA3, but it spins at only 488 rpm. !/info/x-line-energy-z-coachĪnyone have any experience with this tire? 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. (4) Internal 2012 study on MICHELIN X® LINE™ ENERGY™ Z 315/70 R22.5 tyres compared to MICHELIN X® ENERGY™ SAVERGREEN™ XF 315/70 R22.5 tyres.I'm starting the search for new tires, hoping to get them installed in early spring. (3) Internal 2016 calculation: fuel savings up to 2.5 litres/100 km for new tyres and 1.25 litres/100 km on average for the 1st life of tyres with a tractor/tractor-trailer ensemble with a cargo load of 40 tonnes equipped with MICHELIN X® LINE™ ENERGY™ Z 295 / 60 R22.5 or 315 / 60 R22.5, MICHELIN X® LINE™ ENERGY™ D 295 / 60 R22.5 and MICHELIN X® LINE™ ENERGY™ T 445 / 45 R19.5 compared to a tractor-trailer/tractor ensemble with a cargo load of 40 tonnes equipped with MICHELIN X® ENERGY™ XF 295 / 60 R22.5 or 315 / 60 R22.5, MICHELIN XDA2 + Energy 295 / 60 R22.5, and MICHELIN XTA2 + ENERGY™ T 445 / 45 R19.5 tyres (rolling resistance reduced by 26%). Internal comparison carried out at the Michelin research and development centre by comparing the average weight of MICHELIN REMIX™ tyres with the average weight of new MICHELIN tyres in several sizes. (2) MICHELIN REMIX retreading requires, on average, only 20 kg of additional raw materials, which comes out to a savings of 50 kg in raw materials when compared to the production of a new MICHELIN tyre.
