235 75R15 Truck Tires, See How Big Tires Can Change Wheel Horsepower-Great, nice tires for off-road use are important components for the construction of off-road, because they have ground clearance and traction. They also look very good. But they also cost a bit of performance and you can see how accurately you are doing in this dynamic test. Recently it seemed popular for Subarus to give a thick rubber band. We have seen the off-road outbacks on off-road trails, and the owner Crosstrek has a large screw thread for Fork that comes with a small hatchback.
One of these modes is the changing of wheels and rims. As in the video, this car has been driven with Yokohama Geolander Subaru 225 / 60R17 all-season on the 15-inch off-road wheels with tires Goodyear 235 / 75R15 BF companies Allrich.
The upgrade will certainly contribute to clearing the ground and removing the road. Namely, BFGs are about an inch higher than Yokos shares. They also add weight: the video description shows that each well received 11.6 kilograms of undamaged mass.Let’s get the results. The Subaru CrossTrek 2018 is standard equipped with 152 hp and 145 Nm start. On the day that this video was made on that specific sofa, the car produced 141 hp and 131 l.

The wheels will continue to see lower levels of power than on their knees due to the parasitic losses from the engine to the road so that the base line looks solid.
If you release large BFGs, the result of Dynamo is reduced to 127 hp and 122 lv.
What happened then: Rotational inertia, which takes into account the mass of the wheel, will probably contribute to that difference. Simply put, heavy tires and tires mean less power on the road. My friend Jason Fenske of Engineering Explained spoke more about science in this video in 2013.
Of course, our own David Tracy has an excellent guide to everything you need to know about the conditions of slipping and reports on off-road vehicles to supplement their knowledge on the subject before selecting a new wheel for your truck, Jeep or Subaru . It is one of the most important points that emphasizes: Even if you do not take into account the weight of the wheels / tires, the radius of the tire increase without causing a lower force between the tire and the ground, resulting in lower gear.
That the Crosstrek in this video added wheel diameter an inch and a weight of 11.6 kg, but that does not mean the loss of 14 hp and 9 Nm of torque on the wheels do not affect. to change the wheel size on the other wheels for extrapolation. Vehicles.
Also note that the testers have activated this Dyno Mustang only once in every configuration. In general you need to obtain reproducible results in studies to reach a conclusion. However, this remains an interesting example of strength measured by the wheel, which can be changed by changing the wheel of a car.
In view of the practical consequences of big band in this small Subaru, I can promise you that the owner of this Subara will not go through so quickly to an aggressive race. Crosstrek cherry on wheels is the most obvious weakness vehicles, and I can not imagine how this car feels slowly after he fell to his knees for extra weight of 46. 4 kilograms. what happens to fuel consumption ………….
