Default Car rims

As some of you know, I bought a 2010 accord coupe last year. I am thinking of getting some rims for it. I heard that rims can damage a car and void its warranty. Is that true? What if I get rims with the same size and weight of the stock rims (18 x 8 in alloys). I was going to talk to the dealer about this too. Since the color of the car is black with black interior, rims would make the car stand out more. It would also match the door handles (V6 model comes with silver handles) and dual exhaust pipes.

The thing you want to becareful is that going with improper rims can drastically change the drivability of the car. Most people know that you must have the correct size and bolt pattern, but they ignore that rim offset is also important. So long as you don't do anything wierd, they will not be able to void your warranty. You will want to make sure that the overall radius does not change, or the change is extremely minimal since it would otherwise mess up your drivetrain calibrations.

If you plan on going with larger diameter rims, you are going to have to accept that it is going to ride drastically harsher as you must compensate by going with a lower profile tire. A larger diameter rim will also increase the weight of the rim. A good rule is that 1 extra lb of reciprocating weight is equal to adding another 7 lbs of curb weight to your vehicle. I guess I am not a big fan of aftermarket rims.....

If you want to have fun, head over to http://www.tirerack.com where they have an interactive tool you can play with where you load up your car and get a preview of what your car will look like. Quality is important as well, as bad rims can really be bad. I think almost all of it comes from China these days too. Walked into a Michael Tires Plus a few years ago to repair a flat and every single rim on display had a made in China sticker.

The only time wheels can 'damage' a car is if it's the wrong fit. A few years ago when I managed an auto service retailer, some kid went in with a Geo Metro. He had custom 18" chrome wheels he wanted to install. It was the wrong fit. It was the wrong offset. It was wrong everything. We tried to talk him out of doing something that stupid. He refused to listen. I told him I'm not going to have anyone work on that car because it would be a liability for us. Well, needless to say, the kid didn't listen. He still wanted the rims to go on the Metro. The funniest part was when he bypassed me in the showroom and went to the back to one of the mechanic. He offered straight cash if they did it for him. They refused. So he asked for a blow torch so he could do it himself. What a complete buffoon!!!!

Thx for the info. Cool site. If I get rims, I want them the same size, weight, radius, etc as my existing ones so my speedometer info is correct. I also plan to use the stock rims during the fall/winter months. A friend told me about a place that will swap them for free. I might talk to the dealer to see if they know of experience from other owners getting rims or get recommendations. I do like the stock rims since they have the honda name on them but I imagine the flashier honda ones would be pricey. One of my friends told me how he messed up his truck due to rims but he prob used ones that were too big for the vehicle because he likes to be flamboyant and show boat.

I use RonJon wheels on my Acura. They specialize in Honda/Acura wheels.

As everyone said you'll be fine if you keep the same basic offset and radius. There is some room to play with the radius if you can adjust the computer but the offset is very important too. If you stick a wheel too far out besides interference issues with the body you'll also put additional strain on the suspension parts because the center of the contact point will be farther away. Think of holding a stick with something on the end, the longer the stick the harder is is for you to hold.

Not to mention that you'll be needing a new paint job very soon from all of the pebble spray from your tire blasting the side of your car

Unsprung weight is very important for the best ride and handling characteristics.
The best forged wheels weigh the least, even less than stock even though the overall size may be larger.
Next up is low pressure cast rims. This is the process accepted and used by most auto manufacturers to meet specific safety standards, and they also have fairly good weight characteristics. A good choice in lower priced rims.
High pressure castings fill the after-market wheel inventories. They are cheap, and some actually well made, but in general are even heavier than stock alloys.
Generally, I would avoid them. Some of the most recent low pressure models are price competitive and offer other advantages.
Despite the common myth, high quality chrome plating adds very little weight to alloy based wheels. Again, it depends on the quality of the plating.
There are several reputable 'platers' out there that actually use 3 to 5 step processes. This is a lot more than just dumping in an eletro-plating bath. It involves a sputtering process, similar but more sophisticated than powder coating. The pre-treatment of these rims is the most time consuming process, including under coatings of nickel and copper, etc., and what separates them from a plain chrome rim.
Because of the labor involved they are often more expensive than off the shelf rims, especially alloy replacements. These shops carry chromed rims for the most common makes and models, and take your stock rims in trade ('core charges apply'). It is a quality way to upgrade the appearance of your car while maintaining the safety, reliability, and dimensions of a stock wheel. They have advanced clear coatings to protect the finish against harsh winters, etc. too.
Avoid 'painted' wheels that look chrome, in general they have the shortest life in terms of good looks.

Understand the form, fit and function of anything on your car before you consider replacing it. The simplest thing can compromise safety.

I considered upgrading to forged aluminum rims a while back on a previous vehicle until I saw the price tag on them. They are also extremely hard to find for anything other than the most common applications. I'm afraid that what you are stating here is so incredibly significant, because more and more aftermarket rims are no longer of decent quality. However, you get what you pay for and those rims that TireRack sells at super budget pricing are only going to be worth what you paid.

This exactly why I can't understand this obsession among some people to upgrade to the biggest diameter rim no matter what. Some of those rims are seriously heavy, and even require two people to mount on a car. It used to be the riceboys who were into this, but now you have others who are even going as far as putting lifts on old body American cars just to fit supersized SUV rims on them. I can't beleive how many old Caprices, Impala SS'(the original), old Firebirds, Crown Vics and so on I see rolling around like that.

I am not sure any sold by Tire Rack are of inferior quality. It would appear even the least expensive ones they sell, by description, are equivalent in quality to what comes stock on most cars these days. They also provide tutorials on differences and the weights of the wheels, which is very hard to find at retailers that carry a much greater number of assorted wheels.
TR's stock is quite small in comparison.
Are they all forged? Certainly not (but they do sell some), but neither are the ones supplied on production cars except for very expensive models as far as I know. There are a lot of caveats on the dangers of after-market wheels, but in many cases people just want something different, IMO. Going +1 in tire/wheel sizes is perfectly acceptable if guidelines are followed. Whether upgrades are 'needed' is certainly another issue entirely, but following safety guidelines in one's choice is wise. Not to say people will not put most anything on their car based strictly on looks, and there is no law to stop them. But you can't legislate common sense.

The problem with some of these homies running around with lift kits and dub + 10's on their cars is that it does become a huge safety issue that can affect others. A few years ago, there was a famous video of some guy who was running 30 inch rims on his old Firebird with a lift kit on it. It may still be on youtube, but the drivetrain in a typical car wasn't designed to be pushing rims that weigh so much. He floored it and his rear halfshaft snapped like a twig and sent his car barrelling out of control into a wall. It was kind of funny how his rim flew off the car. Also many of these lifts being done are being done by shady people who aren't even doing it right.

Uhh...with all the warnings I may not get rims after all. I may go for subs and amp instead. My car comes with the premium sound system. But it still can use more bass.

If you do this you'll be fine.

Agreed, or get the stocks ones chromed by a reputable shop. Not many around though.

Yeah, it isn't worth it trying to save money and get your wheels chromed by a discount place. Bad things happen when chroming isn't done right.
