I know of 14 different combines that have the 900 metric tires and they blow the bead . These tires are not mounted on the heavy duty rim like a 35.5x32. My assumption is the rim is eating into the bead and weakening the wall. If they would mount the metric tire on the heavy duty rim I believe we wouldnt be having this problem.. Are there anyone else out there having this trouble? Goodyear will adjust the tires at about 40% of new tire price. I think we have a rim problem,not a tire problem.
I've also heard of this happening. Those 900's are junk. I've seen ones that are 4 years old and they're completely shot- cracked sidewalls and beads, constant flats even with tubes, and Goodyear says take a hike, no warranty. 35.5x32's are much better. Haven't seen any trouble with them and they're very popular around here. But I really think large duals are the real answer. Better stability for wide headers and more floatation.
I don't care for them because they don't have as large a footprint as 800/70R38's as they're
considerably shorter and on a dualled tractor creates excessive width, well, more so.
Gleaner had trouble with 800's busting out the sidewall about 10 years ago on the 2 series, and 10 years ago we couldnt get goodyears to stop power hopping on big 4wds. Went to Firestones on the newer 4wds we've bought, and run Firestones on the gleaners now. I'll pay extra for a Michelin before I ever run a goodyear again
900's running on Combines with bin extensions with no problems. Some running the stock rims but they are all Michelin and Firestone no Goodyear. Sounds like your problem might be brand specific.
You need to beaware that most 900 tyres are in fact rice design tyres, meaning they are designed for mud and wet conditions. If these tyres are used for normal hard dirt with high loads as such with a harvester because the treads are so far apart they put the load back onto the bead causing cracks around the bead and also on the side wall where it isn't supported. Have seen this all combines we have sold, yet not one failure with 800/70R38 that are designed for the job. Sorry about the length of post but hope this helps
I'm afraid I have to argue opposite sides of your statement.
900 tires, to the best of my knowledge, were only offered as R1's therefore not specifically intended mud and wet.
However
I agree 800/70R/38 are pretty good combine AND tractor tires.
No apologies needed on post length in fact most here wish I would limit posts to
900/65R32 are R-2 and only available in Goodyear (unfortunetly), I've blown one myself. Don, you may be thinking of 900 60 32's. When I took my blown tire to my local Goodyear dealer (heavy truck and passenger vehicle tire specialists!) He tried to tell me that I had spun the tire on the rim! After we got the new tire a week later we took the blown tire to "farm specialist" goodyear dealer that we should have gone to in the first place, sent the tire to Goodyear and recieved a prorated warranty credit.
So what psi is everyone running with 900s on a combine? I had a 9860 with 900s for a year and I didn't like the tires at all but they gave no trouble at 25psi with a 7500lb header and a full hopper.
In at the tyre service yesterday and saw a 900 firestone off an 8010 that had holes in beetween the the side wall and the lugs. New combine this season and it had only run 100 hours, they were running 44psi.
It seems that the Good Year/Titan tires are having issues with the tire bead breaking down, then the tire looses air then the sidewall goes away. We have Titan 320-50's on sprayers that are doing the same thing. Titan just blames the operator and washes their hands of the problem.
In the 30.5 and 35.5x32 size rice and cane we always had much better luck out of Goodyears over the Firestones. The Firestones would always have the sidewall seperate after about 3-4 years of running. Lots of road miles didn't help much. I lost both front tires on my 9600 in about a week and both had the same problem. Replaced them with Goodyears and when the combines left years later they were still going.
We have a 9769STS ('06) with 800-38 Titan tires front, and 600-28 titans on the rear...one front tire sidewall went the 2nd day of wheat harvest, so I replaced both of them with Michelins...they say you pay for the name but the Michelin is rated to carry 10,000 lbs. more. WHAT A TIRE!! They are very nice. The rear tires started to crack and the facing was spitting, so I called the titan/goodyear dealer and they traded them in ...gave me $500 ea., all told I spent $8600 on 4 new tires to get rid of the Titans...no problems now.
Actually the CEO of Titan said that they will not warranty tires any longer if not mounted on the proper rims... how many failures are caused by using the same rims guys put their 30.5-32 tires on?
What needs to happen then is the factory needs to not mount these 900 metric tires on any rim other than the heavy duty one with strong sidewall steel ring. They are probably charging us for it anyhow, just not getting it on our machines. Please factory dudes-----TIGHTEN UP
The only rim should be the one a 35.5 x 32 is mounted on. It is heavy duty, wish I had picture to show the difference. Somehow you guys got confused with tire size. I started with the 900 metric tire and forum got to talking about 30.5. The 27 inch rim pulls the sidewall inward and therefore cuts into the bead of tire. Will try and get pictures of the 2 different rims that deere is using for 35.5 x 32 tires. Just because it is allowed dont mean it works. Deere just puts the rims on and then its up to the tire manufacturer to fix if something goes wrong with tire. When it actually isnt the tire at all.
