What is a good rim weight to get for my 6gen accord in order not to have too much rotating mass.

My current 18x7 rims + Kumho tires = 43 pounds each wheel

Are these super heavy? Seems like it to me since they are so much heavier than stock.

Thanks

The easiest way to reduce rolling mass is in the wheel itself. Any low profile tire is gonna be pretty heavy due to the thick sidewall, larger contact patch than stock, etc. In fact I think they are all pretty much close the same weight in a certain size that compaines/stores don't even generally post comparison weights like they do with wheels, cause they are all pretty close.

 

sorry, I meant Rim weight not tire weight. Always make that mistake!

Whats a good weight for 18 in rims? Or a rim/tire combo. Does the tire weigh anywhere near as much as a rim does?

Thanks

Haha, wheel weight makes better sense.

Well, one general guideline is that if a wheel weighs less in lbs than it's diameter, it's considered "lightweight". From what I've seen though, it's hard to find lots of lightweight wheels in 18. I guess cause if you are going for lightweight, you aren't going to get 18s.

Your tantrums in 18x7.5 weigh 23.2lbs. Not real heavy, not real light. Mine are about the same...24.0lbs.

So basically your wheel is 23, your tire is 20.

Forged SSR comps are about the lightest I've seen in 18x7.5 at 14.5lbs. Most all the lightweight 18x7.5 are forged, spendy, and unless can be custom drilled, won't work on our lug pattern.

Anything forged is gonna be money, and the lighter cast wheels I've seen in 18x7.5 don't get any lighter than 18lbs. Whether it's worth it to get new wheels for 5lbs less each corner is up to you. Personally, for what I use my car for, 24lbs does the job.

If you really want lightweight, the easiest and cheapest way is to downsize to 16s or 17s.

Well I used to have some aftermarket 16" wheels for my Accord. Each wheel/tire combo was 10 lbs. heavier than the stock setup (43lbs. vs. 33 lbs.) and it was a VERY NOTICEABLE difference, especially in braking. I ended up getting rid of the 16's because of it. This time, for my CL, I am getting some forged 18" wheels that are 15.5 lbs. each, compared to the stock 24lbs, so I am expecting an improvement over stock this time! Anyway as jschmid mentioned, 1 lb. per inch is a good guage for wheel weights...
