4020 TIre Sizes

[esox21]

Just wondering what everyone feels the best front and rear size tire on a 4020?

 

[tomstractorsandtoys]

I like 18X34 rears and 9.5X15 or 11X15 fronts

 

[rockyridgefarm]

16.9-38 rears and 11L-15 fronts

My 4020 has 18.4-34's on the rear and 7.50-18's on the front. Works for me.

I would not want anything more narrow than 18.4 on the rear.

Here is what I do when I don't know what I like 1rst how tall do I want the step , 2cnd what width do I like , then I can match the center , 24.5 x 32 would be different but 16.9 x 38 would be similar in overall height . I am partial to 20.8 x 38 and 11 x 16 , my opinion.

Dad has 18.4-34 rear and 11L-15 fronts and I have 18.4-34 rear with 10-16 fronts. I have a slight "nose up" look and he doesn't. I like how both look. I am not a fan of narrow front or rear tires. I am not sure if the 13.6 or 15.5-38 has any traction advantages but I still favor the 18.4-34 size for function looks and economical cost to replace them. Both of ours are half time loader tractors so front tire weight ratings are a concern for me. The manual listed the 11-15 and 10-16 as having the highest ratings for factory options with the 10-16 as the highest. I haven't looked at this in years and tire qualities have changed I am sure so if that has changed let me know.

our spares for the front is an old set of 9.5-15s and they are so short when on the other end of the axle from the 11-15 let alone the 10-16s. I had the shorty and tall thing most last fall as I donated a tire to the gravity wagon lol. I thought the 9.5-15 was perfect for the 2010 we used to have.

My vote is 18.4-34 - Rears, 10-16 - Fronts.

18.4-34 rears work well with both 11L-15 and 10:00-16 fronts. The 11Ls being a tad shorter if you like a level to slightly nose down effect. The 10:00s are a bit taller and will give you a slight nose up effect. Both have a nice wide footprint that is much better for loaders. I personally do not like skinny front tires. If I had to choose between the two, I would choose the 10:00-16s.

We also have one 4020 narrow front with 15.5X38 rear tires and 7.5 X 15 fronts. It is more of a chore tractor and we cultivate,rake hay and pull silage wagons with it.

I usually have 18.4x34 Firestones with 11L15 fronts .I prefer 16.9x38 over 18.4x38 as they look a little more in proportion to the tractor it takes 10x16 fronts to even them out.The 16.9x38 will give you a few MPH . I have seen some with 20.8x34 with the bigger fenders but prefer smaller fenders.15.5x38 look out of place as do 16.9x34 but you see some that way.Just what I like

 

[Mike Aylward]

I run 18.4-38 rear and 11:00-16 fronts on both of mine. Mike

 

[sideconsole4020guy]

18.4x38 and 11Lx15

 

[ASG]

16.9-38 or 18.4-34 rear with 10.00-16 or 11L-15 front.

 

[rockyridgefarm]

18.4-38 is just too much rubber unless you have the 4020 turboed or you're not actually farming with it.

 

[sideconsole4020guy]

I got a kick out of that comment. We farm with 2 4020's with 18.4x38's. Dads has had them since the 80's. And they are not turboed

 

[coonie minnie]

I must not be farming with mine either. Or when I have 18.4 34 and a set of duals on.

 

[sideconsole4020guy]

This must not be farming either. Please tell me the definition of farming.

 

[sideconsole4020guy]

I am really kinda bummed that dad and grandpa lied to me all those years ago by telling me we were farmers. And I must be a liar when I tell people I farm along with having my tech job at a JD dealer. I mean since tire size dictates if you are a true farmer here are some non farming 18.4x38s on a non farming 4020. This is dads 4020, the other one was mine.

 

[rockyridgefarm]

I'm glad you like your 18.4-38s. Allow me to rephrase my comment -

18.4-38 is too much rubber when working on hilly ground. Makes a 95 hp tractor poochy when climbing.

JD engineers must no have agreed with you as 18.4X38 rear tires were an option for late model 4020's when I sold them when they were NEW. 20.8X34 rear tires were also offered for 4020's

 

[sideconsole4020guy]

Most of our ground was not table top flat we had plenty of hills as well. Pulled 5x14 pull type plow, 16' disk and 16' field cultivator all day long. The best part of the larger tires is 22 mph road speed.

 

[rockyridgefarm]

In my area, a 4020 is unlikely to be happy in front of a 5-14s, especially with big rubber. 4-16s would be a struggle, 4-14s would be fine. 16 foot disk will gave a 4430 a workout if you're pulling harrows behind it.

 

[sideconsole4020guy]

I don't doubt that. I should ads that the cabbed 4020 of ours has repeatedly put 120hp on the dyno and is full of fluid and weighs in at 13,000 so it is set for getting work done. It had 16.9x38 on it when dad bought it but it sat nose up and he didn't like that. He also went to the big rubber because of the faster road speed because they used it for pulling the corn sheller around as they did custom corn shelling.
