I've had a 2001 Corolla LE for about four years now, and I've just bent one of its steel wheels beyond repair for the third time. Once hitting a block of wood that fell out of a truck, once hitting a piece of tire tread on the freeway, and this time I'm not even sure how I bent it. I do not think that it is normal for wheels to bend so easily, and the Toyota Dealership here wants something ridiculous for them. I do not remember exactly, but I think it was in the $90 range. I've looked around a little and have been completely unsuccessful at finding them at wheel and tire shops. Because I do not want to have to buy any more of them, I have decided to buy aftermarket wheels.
I am aware that changing the diameter, width, or offset of the wheels can have effects on the steering and suspension, but I don't know how different they have to be for the effects to be noticeable or what the effects would be. Somewhat more importantly, I don't know exactly what size my wheels are. I'm pretty sure that they are 15" x 6" with a 4-100 bolt pattern, but I haven't been able to find this information anywhere.
I think that a lot of people put aftermarket wheels on a car because they think it looks better, without regard to effects on performance. It's not uncommon to see Civics and things with camber issues or tires that have been rubbing on things because of aftermarket wheels that don't fit properly, and I want to avoid that. In fact I would rather pay $90 every year or two than sacrifice any handling or ride quality.
So, if anyone knows the offset of the stock wheels for a 2001 LE, how much they weigh, whether or not 15" x 6" 4-100 is correct, or how changing these things will affect the car, that information would be very helpful.
I am currently considering the MSW Type 15 on tirerack.com. I've never heard of MSW, but they are cheap, reasonable looking, and pretty close to the dimensions of the stock wheels (I think).
