Best Wheels

I've had my '93 Honda Accord for the past 8 years. I have 17 inch wheels and have not changed the springs or shocks since I've had it. Lately I've noticed a rougher ride, when someone is an the back seat, the tires rub, and if i hit a bump the car is extra bouncy. I'm hoping to upgrade to 18 inch wheels. Should I upgrade the suspension too?

I've had several dogs over the years and for some reason, they have all been strangely fascinated by the smell on car wheels/tires. They seem to be more interested in the wheels. I understand that the tires are probably going across a wide variety of interesting-smelling surfaces, but their interest definitely seems to be on the wheel itself. Anyone have any ideas?

I have a 2005 all terrain fisher price 4 wheeler that we paid 9. It has a detachable cart and is battery powered. My son used it for two summers so the tires are a little worn. Some friends said they would buy it but I don't know how much to charge.

I just put 20" wheels/tires on my 2004 Pontiac Grand Prix GT. I want to lower the car now and would like suggestions of possible damage to car, engine, suspension or any part of car. Any ideas for price and product to lower car safely would be helpful as well. thank you.
The regular size that I bought the car with was 16" tires. Can I get information on lowering the car without issues down the road. I would rather do all work at once to prevent problems later.

I drive a '02 Volvo S40.

Its a good car, and I don't want to get rid of it, but its plain and a bit more conservative than I would like.

If I were to put larger wheels and low-profile tires on it, how large of rims could I fit without cutting into the wheel-wells? The standard wheel on my car is a 15" diameter.

I have a cadillac cts that comes stock with 16inch alloy. I would like to upgrade to some 18inch black wheels but a friend of mines told me that i will lose a certain amount of horsepower/torque for every inch i go above the factory specs. A friend of mines had a 2000 pontiac grand prix that came with 16inch alloys and when he upgraded to 18inch wheels his car did seem a bit slower. What do you think? Do you think adding bigger wheels and tires to a car slow it down? If so, by how much?

I want to put 16x7" custom wheels on my car. My factory ones are 16x6.5". Will I be able to use the same tires or will I have to buy new tires, too? I am not sure about the 1/2" difference.
tgomez, is there a way to contact you?

If I were to simply take my wheels off my car to paint them (with the tires still on) and put them back on, do I need to have any adjustments\balancing done to them again? Or will they still be the same as before I took them off?

Thanks

My Nitro RC car wont keep the front tires on the ground when turning so i cant turn real sharp and its really frustrating. Is there any way i can tweak the suspension or something to make it stop?

I need to get new tires and there is a make/model of my car with aluminum wheels and one without and I don't know the difference (yes, I'm a girl!)
