Tires on Pontiac Trans Sport (Понтиак)

The Pontiac Trans Sport minivan was produced from 1990 to 1999, spanning two generations that differed significantly not only in appearance but also in concept. The change in design, approach to materials, and technology led to the fact that early versions were perceived as experimental "space" capsules, while later ones became much more traditional family cars.

First Iteration

The debut version, released in 1990, was built on the U-body platform and immediately stood out with fiberglass body panels installed on a steel space frame. This reduced the risk of corrosion, but the body's rigidity had to be ensured by an enhanced power structure and rather specific solutions. In particular, the body panel mounts received special dampers. The glazing line was huge, and the long sloping nose made the minivan look more like a space aggregate.

At the same time, the chassis was distinguished by simplicity: McPherson struts at the front and a rigid beam at the rear. At the start of sales, a 3.1-liter gasoline V6 was located under the hood, which was later supplemented by a 3.8-liter power unit of the same design. Both engines used an electronic fuel injection system and a control unit with a self-diagnostic function. They were combined with a 4-speed "automatic" with adaptive switching logic and an oil cooler integrated into the transmission housing.

The interior looked unusual even for the 90s. The instrument panel was wide, with a deep tunnel, the plastic was soft at the top and more rigid at the bottom to withstand constant loads. Textured inserts under graphite and dense velour on the seats were often used. The sliding side door worked on rollers with protection against dirt ingress. The equipment included climate control, a separate rear heater control unit, an advanced audio system for its time, and an on-board computer with an enlarged display.

Second Iteration

In 1997, the Trans Sport underwent a radical change. The concept of a "futuristic shuttle" gave way to a design with classic minivan proportions. The body panels were now fully steel, except for a few plastic elements, which improved passive safety and simplified repairs. Additionally, the car technically broke its connection with its predecessor, transitioning to a significantly modernized U-body platform developed by GM. The chassis changed not only in components but also in settings. It became noticeably softer, while the car's rolls were significantly neutralized by transverse stabilizers with an increased cross-section. Another innovation was the 3.4-liter gasoline V6, which underwent a modernization cycle, during which it received a fuel injection system with an extended range of air-fuel mixture correction and a modified exhaust system. This significantly increased traction at low revs, reducing fuel consumption. The automatic transmission received a different hydrotransformer, and the cooling radiator had a separate circuit, which substantially reduced the risk of transmission overheating during prolonged high-speed driving.
The interior became more familiar: the front console lost a significant part of its futurism, providing a more ergonomic arrangement of controls. Another important difference was the plastic with a soft texture. A separate audio system block for rear passengers and an updated air conditioning system with a more powerful evaporator appeared.

Most of the produced specimens were equipped with 15- and 16-inch alloy wheels and tires. When choosing them, it is necessary to consider the sensitivity of this car to the height of the profile and the stiffness of the tire sidewalls, the load-carrying capacity of the wheels. For this reason, it is best to select this product in the "Mosavtoshina" online store.
