With one constant tire pressure, your bottom line’s squeezed.
Field: Low Pressure & High Efficiency
Low tire pressures in the field fight pinch-row compaction and help your planter pull easier.
Yields- Fuel Efficiency
Road: High Pressure & Low Rolling Resistance
High tire pressures on the road allow your tires to carry a loaded planter without overheating, even at today’s fast transport speeds and long distances.
- Fuel Economy
- Secure handling
- Longer tire life

Fight Pinch Row Compaction And Boost Your Yields
Michelin Study
A 2021 study showed a 6.4% yield increase on pinch rows on John Deere NT planter and tractor with CTIS installed.

AgRevival’s 3-Year Study
Designed to test the effects of five different tire pressures during planting on yield: 35 psi, 28 psi, 20 psi, 12 psi, and 6 psi. We chose a wide pressure range to reflect the growers who run their tractor tires at roading pressures in the field (the 35 psi group) all the way down to more ideal field tire pressures. (All tractor and planter tires were set to the same pressure.)

Ag PhD Study
In the spring of 2022, NTS Tire Supply outfitted the Hefty Brothers’ (Ag PhD) John Deere 8R 370 and DB60 planting setup with a PTG central tire inflation system (CTIS).
Hefty recorded a 3.4% increase in yield using the optimized pressures made possible by the central tire inflation system.

Farmers Review CTIS
Tracks come with a lot of maintenance . . . tracks are 4 to 5 times more than what I have into my system. That’s a huge dollar amount. That takes a lot of saved money to get that money back in your pocket, and we just didn’t see it. [CTIS] is a clear choice . . . it just works.
I saw 4 bushels consistently. It wasn’t 4½, it wasn’t 3½, it was 4 bushels. I was skeptical at first, but it has proven itself very quickly . . . If you want more bushels, just give it a try.
It travels good. Doesn't take too long to inflate the tires . . . It just uses the factory compressor that the planter came with . . . It does its job of lowering compaction.
3 Strategies for Planter CTIS
Equip planter only.
Minimize yield-robbing compaction when you drop your planter’s transport tires to the lowest safe pressure in the field. Inflate tires to max pressure on the road for low rolling resistance to extend tire life and save fuel. NTS only recommends this strategy if you pull your planter with a track tractor.
Equip planter & tractor rear axle.
This is the minimum setup NTS recommends if you pull your planter with a wheeled tractor. A portion of your planter’s weight is transferred to your tractor’s rear axle on the road. The high tire pressures needed to protect your tires during road travel will impact your yields in the field.
Equip planter & both tractor axles.
This is the best solution for planting setups with tractor-mounted straddle tanks. Or if you want to optimize your planting tractor for other operations such as tillage, carting, and manure hauling.
