Combines anybody make a decent tireIJ

It sounds more like a ply rating problem if you blew Firestones and Goodyears. And how many bushels are you hauling full grain tankIJ It states very clearly in my Gleaner Rotary manual that loaded, you should not exceed 5 mph as tire failure is very likely, with other structural damage or failure is likely. Too few of sidewall plys will definitely make a blow out failure possible. If it is the same dealer for both Firestone and Goodyear's then the dealer isn't giving you a heavy enough tire for the machine.

It would be interesting to know how many plies, what head size you run, and if you are operating on side hills.

25-30 n seems quite high to me. Havn't looked for specs but on that big a tire 30n is exerting exstreme force on the sidewall area. The ride must also be lousy. Here we use duals on slopes like this _ with no problem at 8-12n. lol

I like using big diameter Trelleborg's as I get considerably better flotation as well. They have heavy ply ratings now as well.

I have a couple more thoughts on tire failures as well. Are you "punching" the sidewalls with corn stalksIJ We went through a bunch of tires before Firestone people put log skidder tires on ours. That stops the BS of stuff going through sidewalls. One other thing you might consider is going with smaller tires and running duals.

Go with the Trelleborg 900_60-32. It will fit right on your current rims, or if you want to you can have you rims widened about 2-3". It has a max combine load rating of 26,554 lbs at 45 psi. If you follow the pressure recommendations your sidewall problems should be a thing of the past. Where are you locatedIJ Do you know what your max loaded weight isIJ

The Goodyear service manual lists MAXIMUM pressures for 30.5-32 tires as 18 psi for 10 ply and 20 for 12 ply. Good luck.

Goodyear 30.5 x 32 14 ply rating has 9900 pound load rating at 22 psi. They used to allow a 70% increase (16,830 per tire) for speeds less than 5 mph. Goodyear's 900_60R32 has 15,700 pound load rating at 26 psi and 30 mph, but the tires must cost big $$$.

Are you sure its really the tires faultIJWhat I mean is some newer varieties of corn (bt corn)have stalks that can spear a tire causing a slow leak which in turn causes you to run a low tire which leads to sidewall failure. I have found that header mounted stalk stompers smash the stalks and save wear and damage to my tires.May-wes makes and sells them. A word of caution,my tire guy says to be very careful airing up a low combine tires,sometimes the sidewall can be damaged without you knowing it and it could explode violently killing anyone nearby.He said he seen it happen.BEWARE and Be safe!

I have Michelin tires on an R50 and farm very hilly ground with grain bin extentions. I run a 6 row 30 inch corn head and a 20 foot platform. They have three choices in the XM28 large volume tire and one in the XM27 style. They have larger tires if you would want. I have the XM28 on the drive and XM108 on the rear. I have never had a flat after changing and they were put on in 2000. They have a great warranty, if needed, and the combine roads with out tire hop and rides like your on air
