How much gas and speed will i lose with 19's

[NMBDC]

I drive an acura rsx type S it runs at about 200hp. it has 16" rims with a 55 tire. I am looking at getting a 19" rim with 35 tire. First of all how much will that raise it? Second how much speed will it lose and how much of a difference will it make with my gas mileage? the rims i am looking to get are ACE Manta if that will help at all. I am not sure of the weight but any help would be great.

If you go 215/35-19 you will have the exact same diameter as your original tire so no change in gearing. If you gog 235/35-19 you would have 1% taller gearing which would be better for fuel economy but any gain would be outweighed by the heavier rotational weight.

As for specific changes in fuel economy due to heavier wheels and tires best to check with what other RSX owners have experienced by going to the RSX section of this site or a RSX specific site.

Ace Manta 19" is going to be over 30 lbs. each, that's just the rim. You are definitely going to slow your 0-60 time and your gasoline usage depends on your driving style. If you want bigger and lighter rims, check out 17" O.Z. Racing Superleggera, Racing Hart CP-035s, or any rim by Volk Racing.

Putting on 19's is a huge step. First of all, besides the fuel economy and loss of torque, your suspension will get really beat up. 19's with rubber band tires will really let themselves be known. With time, they can kill your suspension. Suspension geometry may be upset by such a large change in diameter and especially by such a large increase in weight (even with overall diamter still same as original). If you really are considering buying such monstrosities, go with the lightest possible rims- but they cost a pretty penny. Also, get a beefier suspension- that is, shocks and stiffer springs. Regarding torque, you will notice a decrease in acceleration. And with plus 4 sizing it'll be significant. Since your car has rougly 200 hp and probably about the same in torque- you'll definitely feel the difference. The lightest 17*8 that I have seen, for example, were 12.9 lbs per rim, tire not counted. Imagine, the lightest 17's*8 being roughly 13lbs without tire. Compare with 19's....they'll probably be about 16lbs the lgihtest. Add about 8 to 10 lbs for tire (if not more) and you got some serious rolling mass on your car. Compare with stock rim and you'll get a 5-8 lb difference without tire. Also, larger and heavier rims will wear your brakes more than stock. There will be a difference in braking distance. Heavier rims require more force to stop. So a new set of rotors will be a good idea (preferably cross drilled and vented). Considering all these nuances it's a good idea to think this over. My suggestion- 17's. Maybe 18's. Engineers obviously have rim size in mind when they design the suspension. And it isn't a 19". Case in point. I had 205/65/15 tires and 15*6.5 rims on my '02 Accord. Switched to 215/50/17 tires and 17*8 rims that probably weigh about 6 lbs more than stock. I feel a difference in acceleration. Less torque. And brakes work harder. THere you go. Hope this helps.
