Any power loss issues when applying larger wheels other than stock????

[plane16j]

there may already be some threads out there about this. but i was wandering what kind of power loss would take place with appying larger wheels on a 240 (mostly stock) like 17's.a friend of mine threw some 17's on his 95' sentra. (those are some weak @$$ cars by the way ) and has noticed significant power loss durung acceleration.

I wouldn't say a power loss, possibly a lag in power transfer due to higher rotating mass of the larger wheels and tires. Only the rate of acceleration has decreased not the total power output of the engine.

The larger wheels are obviously heavier but more importantly a large part of that weight is now half inch to an inch or more depending on tire size away from the center. This causes it to have more rotational inertia, it takes torque to now turn that larger inertia which makes it and even bigger parasitic lose from the drive train. That and can have a negative effect on handling from more unpsrung mass, but lower profile tires offset that. but since where the mass is more important than how much it is pay attention to the farthest thing out, your tires, different ones do way different amounts.
