Does anyone know the weight of the new 19” Sport wheel or the weight of the wheel/tire combo? Logically, they must be heavy. I am assuming that’s why our cars have a 2 mpg penalty for both motors as compared to the 17s on other Accords. Of course, added wheel weight serves to negatively affect virtually all driving dynamics; ride, handling, acceleration, and braking. They only improve lateral grip. There is another possible downside by changing to aftermarket wheels. Our OE wheels are beautiful.

I'd assume it'll be a few pounds extra per wheel, but the information isn't listed on the owner's manual at all. Honda only reveals the tire size and pressure psi for the tires. Maybe the service manual will have it, but that's usually reserved for the dealership unless you buy one from somewhere.

Yeah I cant find any information about the weight of the stock set up. Didn't think it would be enough to cause a 2MPG difference between trims, is that the only difference in components? I think its more than likely that those who are focused on their Accords performance, will go for aftermarket set ups anyways. Larger tires make sense on a FWD car.

Not necessarily. Larger tires can negatively affect handling precision. These tires are are very large anyway, at least for the size/weight/performance of the car. I have noticed some tramlining with mine. As we know about mass, it wants to remain at rest when at rest and remain in motion when in motion. Increasing the speed of rotating mass (acceleration) requires more power and, by definition, fuel. Decreasing the speed of rotation (braking) requires more braking. This is a flywheel effect. Reducing the unsprung weight allows the wheel to follow the changes in the road surface improving both ride and handling.

Car manufacturers are concerned with durability and cost. This can compromise performance characteristics of the wheel design. Current styling trends seem to demand very large wheels and lower profile tires. A few years ago Car and Driver magazine compared performance characteristics of 15/16/17/18” wheels on a VW. Tires were sized to keep the OD the same. In every case the larger the wheel the slower the acceleration, the longer the braking distances, and the most fuel consumed. No, there is no other apparent difference between the Accord with 17” wheels and one with 19” wheels. The 2 mpg difference applies to both the 1.5 and 2.0 engines. During my car shopping, originally I had decided on an EXL 2.0T because of the difference in the cafe numbers. I assume there is a similar difference in the braking and acceleration. For me, the value factor was better with the Sport model.

I purchased aftermarket wheels for my 2011 GTI and reduced the wheel weight from stock by 10 lbs per wheel...significant! On my 2015 GTI, I did the same with 6 lb reduction per wheel. All wheels for both cars were 18”. Tire weights seem pretty similar. Guys tracking their GTIs are getting good results by reducing the wheel diameter and upsizing the tires to compensate. I am thinking of 18” wheels for my Accord. Tire Rack has lots of dimension data on their web site.

Well I can understand automakers trying to save on cost for the oem wheels, but durability is another issue altogether. 10lbs a wheel is a huge amount of lost weight, and I can see the loss of 40 pounds overall being pretty significant in terms of performance. There are no concerns with durability with these lighter aftermarket rims? Definitely let us know what you decide on for aftermarket wheels as it seems you do your research aha.

I purchased Enkei wheels for both VWs. Certainly not top of the line, but Enkei is a reputable Japanese company manufacturing their wheels in the US. Actually I had no issues with these aftermarket wheels, but did have lots of dented wheel problems on the 17x7.5 OE wheels on a ‘10 Accord I used for extensive sales travel, 175,000 miles over several years. Both sets of Enkei wheels totaled no more than 50,000 miles in summer only. Still have the ‘15 GTI with the Enkei’s.

I need to start with the wheel weight of my 19” Sport wheels. May have to drag my old body out to the garage with my bathroom scales, jack, and lug wrench. Wheel weights for possible replacements are easily available.

Maybe your dealer is willing to divulge that information if you give them a call, otherwise it's the bathroom scales. Couldn't even find the wheels on those OEM Honda parts sites.
Even if they're a bit hefty, are you planning to just use the OE wheels until they get dents and then move on to lighter aftermarket ones?

No, I plan to make my move soon. Might as well enjoy the best combo through the life of my new toy. Just need to do my research on wheels and tires for the best performance/value. I am going to 18” wheels. Found the weight on our Sport wheels., 31.6 lbs. Enkei has several styles at 20-21 lbs, a very significant saving.
