    Default L2900 Replacing 7.2-16 R1s???

    I need to replace the Goodyear 4 ply 7.2-16 R1s on the front of my 4wd L2900.

    Local tire shop said that Goodyear did not make that tire any more but that Titan had a 7-16 R1 6PR that would work. They ordered the tires, mounted them on the rims I had dropped off. The tires looked like they had been sitting out in the sun for a long time. I checked the manufacture date and found that the tires were over 2 years old so I returned them.

    Where can I check the diameter of the 7.2 vs. 7.0 vs. 7.5?

    Anyone have any experience with Starmaxx or BKT tires?

    Thanks!

    I spoke with J Ogden at Titan / Goodyear Ag regarding the rolling circumference of the factory original Goodyear 7.2-16 Dura Torque tires. The rolling circumference was 88.6".

    Titan has a 7-16 6 R1 Hi Trac Lug TL with an 89" rolling circumference.

    Also, Titan still makes the Goodyear 7-16 DUra Torque TL (also a 6 ply) with an 87" circumference. And since I still have the original rear tires on the tractor, which have to now have a shorter circumference, I'm going with these tires.

    FYI, J said that tractor manufacturers usually shoot for a 1-5% lead ratio for the front tires, and that it would be good to know if the original tire combination was closer to 1, 5, or in the middle if you have to decide whether to go up or down slightly.

    I have a L3010 with GoodYear R1 tires. Rear: 12.4 X 24 Front: 7.2 X 16
    My dealer told me that the lead was about 5%. Don't know if yours is the same or not.
    I am interested in your problem because my fronts are quite worn while the rears look almost new after 10 years.
    I am not sure but I believe that I have read some complaints about Titan. Something you may want to check out.
    Good Luck and let us know what you do in the end.

    I've got 7.00x16 Carlisle Farm Specialist R1's on the front of my L3400. They're probably a good bit cheaper than the Goodyear/Titans are. I've had pretty good success with them, and they definitely stand behind their products.

    Last summer I was doing a lot of heavy loader work, and noticed the sidewalls had bulged at the base of each tread lug, and there was air in the bulges. Obviously the tire was becoming delaminated. I found out after the fact that I was about 11 pounds low on inflation pressure for loader work. Either I overstressed them or they were defective, the end result was the same. I called Carlisle, told them what happened. 3 days later I had 2 new tires delivered to my door free of charge.

    They warrant them 100% for the first year, and pro-rate them for the next 4 years. These were 2 years old, but they still replaced them for free. I call that pretty good support. I installed them with tubes this time, if they do delaminate again because of underinflation at least the air will be contained.

    Hi Mac,

    Starmaxx and BKT are both quality import brands, however much more experience with BKT.
    BKT only makes the 7x16 in 4 ply...not good for tractor with front bucket loader.

    Gordon and Mac,

    Industry "rule of thumb" with 4wd tractor and ratios front to rear = keep within 1/2". Now this relates to using different size tires on the front or back (usually happens when going to ag tread to turf tread). So when you are talking about 88.6 to 89" rolling circumference (7.2x16 vs 7x16), no problems. Imagine how big a difference the rolling circumference of a worn our 7.2x16 and a new 7.2x16? Hope that helps.

    BTW OTR still makes a 7.2x16 and in an 8 ply.

    Sean,

    Carlisle is definitely a quality brand and to make a dent in the farm tire aftermarket, they need to be head and shoulders above the competition in customer support. They are the new guys in town (ag and ind) so they need to impress.
