It is paired with a new, lighter Hussla wheel, the Winton changes expected to give drivers greater freedoms on camber set-up.
They also deliver a significant ride-height reduction, paired with changes introduced earlier this month at the PIRTEK Perth SuperSprint.
Running at Winton on Friday consists of two practice sessions and ARMOR ALL Qualifying, with three races to be held across Saturday and Sunday.
“The new wheel and tyre package follows the introduction of modified front dampers and the repositioning of rear frames in Perth, which saw teams drop their ride height by 10mm,” Supercars General Manager – Operations, Kurt Sakzewski said.
“At Winton the SuperUtes will run 45mm lower again.
“As we move forward we will continue to make technical enhancements to the category as part of our program to improve the ECB SuperUtes series for both the fans and the drivers.”
A field of 13 SuperUtes will tackle Round 3 of the 2019 season this weekend.
That includes five debutants; father-and-son pair Gerard and Jaiden Maggs, Craig Thompson, Jeff Watters and Keven Stoopman.
Gerard Maggs and Thompson will be in Toyotas, and Jaiden Maggs a Mitsubishi Triton alongside Dakar Rally winner Toby Price, making his first start of 2019.
Aussie Racing Car regular Watters is racing a second Ford Ranger, and Stoopman the Peters Motorsport Holden Colorado.
Price comes into the field for Elliot Barbour, who misses the Winton event due to a broken ankle.
Kiwi Tom Alexander leads the 2019 ECB SuperUtes Series having won the first ever races for the Isuzu D-MAX in Perth earlier this month.
The Ross Stone Racing driver, who took out two of the three Winton races in 2018 in a Holden, leads Barbour by eight points.
Defending champion Ryal Harris sits third in his Mazda BT-50, 12 points behind Alexander.
