Yes and no. If you use a tire size calculator such as this one--- http://www.miata.net/garage/tirecalc.html
And keep the overall size the same it will make it a smaller profile tire and it will ride worse and tires will be much more expensive I would think. If you go with the same sidewall height (does not mean it will be 60 series to 60 series as a wider tire will be taller at the same number series) it should ride similar but it would be taller overall and will be harder to stop. That is why big brake upgrades go hand in hand with the upsizeing of wheels. Also if you go bigger rim with a smaller sidewall to keep the overall size close it will preload you suspension and that will affect ride. You will in effect have less shock. No easy answer it is a game of compromises. That is why I stayed with a stock 16 on my Camry and just changed rims. I am too practical and drive way to many miles to put up with a harsh ride and broken lips, shocks, etc.

To me there really isn't much change in the ride from my Avalon going from 17s to 20s if anything it helped with road feel and was a benefit. In my old car (04 Acura TL) I also went from 18s to 20s and could say ride felt pretty much the same. I think as long as you stay with at least a 35 series tire you will be fine in regards to ride.

Buy the lightest wheels you can afford. At least try and avoid buying a larger wheel that is heavier than the stock wheel. Best case is buying new wheels that are lighter than your stock wheels, but that means forking over a lot more money.

Wheel weight has a lot bigger effect than the weight inside the car. The weight is un-sprung and rotational. Heavier wheels decrease mileage, lower the handling performance, reduce braking distance (which is why heartdisease recommends a big brake kit upgrade), wear out your brakes faster, and wear out suspension components faster.

Here is a short explanation that is easy to understand.

If you upgrade to wheels lighter than stock, then you don't need to upgrade the brakes really. The lighter weight will offset the rotational internia from the larger diameter.

Upgrade your brakes if you decide to install much heavier wheels that are also larger. If the wheels are only slightly heavier, then it shouldn't really be a problem either.

heartdisease was just wanting to make sure that you don't go install 20"+ DUB chrome wheels that will add 60lbs+ a wheel over the stock weight, and have you burn through your brakes, or get into an accident, shortly afterwards.

Tirerack lists weight for a lot of their wheels, but not for all. You can research wheels on Tirerack, and then shop around for the best deal.

I do not know what the stock 16" wheels weigh though. Are they Steel with hubcaps? heartdisease may know the answer to this.

Someone here on TN weighed them in at 23lbs for the Gen 6 steel wheels, and other 16" steel wheels from other cars are around the 20-25lb mark. So that should be you are aiming to get below. Worst case scenario, do not go heavier than 25lbs per wheel. Best case scenario would be to get wheels less than 20lbs, but 18" wheels that weigh less than 20lbs are expensive. (I warned you earlier :p:)

Do you have a Gen 5 or Gen 6 Camry?

See if this link works.

It should have a list of 18" wheels listed from lightest to heaviest that should fit your car. You can take a look at the list and find the styles you like. There are some low cost light 18" wheels, but they are also "cheap" in craftsmanship and should be avoided.

The Enkei's that are listed are of good quality, and are light without being too expensive (about $300 a wheel), but I do not think the skinny spoke design will look good on a Gen 6 LE. But, it is all up to your opinion of what looks good. OZ is an excellent brand, but are some of the most expensive wheels, but if you can afford them they are well worth it.

EDIT: Also, I would recommend sticking to 8" width or wider wheels. There are a few 18x7.5 wheels listed and 18X8 or bigger will give you a better tire selection to choose from as not as many tires are made for 18x7.5 wheels, plus the wider tire will give more traction.
