7820 tires
I founded this photo in the John Deere 7020 series brochure. Can anyone tell me if the rear dual tires of this tractor are 620 or 710? I appreciate your answers.

Re: 7820 tires
710/70R38 and 600/65R28 it is the standard size in europe together with the 650/65R42 and 540/65R30 but these are the 710s.

I think 710/70 R38.

Lennart in my area they put 710/ 70 R42 under the 7020/30 series.

Re: 7820 tires
guys thank you all for your answers. It´s very rare to see one of these tractors with 710/70R38 duals as this one.

Re: 7820 tires
Yes Victor, I... third... that. They're definitely 71070R38s, Firestones it looks like. It is also possible 710/75/R34s, but unlikely.

We have 710/70/R38 Michelins on our 7630 and I'm rather regretting it. Doing it again, I'd get the 710/70R42s. I think the added height would be good for a number of things, including clearance over the hay swathes.

The neighbor has 710/70R38s on his 7920, and the tiniest damned tires you ever did see on his 7820.

I'm glad to see you finally got your hands on the 7020LF brochure. ;-)

Re: 7820 tires
Josh, thank you very much for your answer. I didn´t knew a few inches in tire size could make such a difference. In CR most of the 7800s, 7810s and 7820s come with 710/70R38 single tires (I haven´t seen any 7830 yet).
Is it difficult to see a 7000 tractor with 710 dual tires?

Re: 7820 tires
It doesn't make much of a difference really. Overall diameter of a 710/70R38 is 76.7 inches, while the R42 is 80.9 inches. The R42's are capable of handling more weight, although a downside is you have to be running higher tire pressure.

I have yet to see a 7000 with dual 710s. It is unlikely to see 710s period in this area, and usually not until you get to big 4wd articulating tractors.

People here are finally starting to take tires into consideration. Before, people couldn't have cared less about height, width, or brand of tire, just made sure it had a normal tread and that was that. Half of the guys in this area couldn't even tell you which way their tires face without looking at them.

Even the neighbor with the 7920 sitting on 710s, he didn't get them on purpose, it was sitting on the lot like that and he didn't even know the size when I asked him.

Prior to 2006 we didn't think about tires at all, but when we got the 7630 I made sure I ordered what I wanted.
My salesman just went "O_O that's a lot of rubber!"

Re: 7820 tires
Josh you´re absolutely right, when people are making such an important investment as a tractor, they should know which tires are the best for the tractor purpose.
Thanks for the answer.
