My new wheels! (PICS)

I thought your goal was just to get better gas mileage on your Lanos, and other than that, you would keep it stock.

Couldn't resist the urge to mod, right?

LoL, I'm just kidding, keep up the good work, looks nice.

Actually, I said I was going to leave the engine stock, other than modifications to it to get better gas milage. The only thing I can think of that may help gas milage is possibly a new exhaust. I just hope that if I do replace the exhaust, the milage goes up & not down.

It is my Leganza that is being left 100% stock.

wheels probably can increase mph if they're smaller or if they're just lighter... well i think it would

hey oz.. you should at least get a UD pulley for the leggy!!

The new wheels are considerably lighter in weight.
Each one is only 18 pounds.

And no, I'm leaving the Leganza stock. It still even has the orrigional valve stem caps! LOL

OZ, do you know how much the sport rims weigh? Because I thought they were pretty light...

even if you go lighter if the wheels are bigger in diameter you lose power.... which im guessing wouldnt help gas either. I gets tricky though... i mean basicly if the wheels are the same weight, but bigger you lose power... but if they're lighter to it gets complicated

I went from the stock 14" wheels that had 185/60/15 tires to 15" wheels with 195/50/15 tires.
By making the side wall height smaller, from 60 series to 50 series, the outside diameter of the wheel is the same as the orrigional stock wheels.

So, with this in mind, the outside is the same size, but the weight is less.
However, there is slightly more tire to ground contact area as the tires are slightly wider. This may or may not be a big enough area increase to reduce gas milage. So far, I have not seen any increase in how much gas it uses.

It doesnt matter if you have a smaller profile tire... there is still more weight on the outside. But you going with only an inch bigger and being lighter its probably equal.. its really hard to figure out.

Think of it this way...if you spin a bowling ball around its not too bad.. but then put the bowling ball on a string and try to swing it around, much harder, right? Thats what i mean. Even though i was going to move up to an 18inch wheel (over 17) and i was going to drop 4pounds per wheel i was told that i would probably still end up losing power.

Only because your stock wheels are lighter??...
Maybe they were comparing your stock wheels to your aftermarket ones.

nope.. comparing current wheels to ones i planned on getting.

The stock 15s are the same weight as the 17s i have now even with the extra thick sidewalls tires

I understand what you are saying, but what I have is not what you are thinking about.

The wheels I have are now 15" and the old stock wheels were 14".
While the diameter of the metal has gotten larger, the tire has gotten smaller.
The overall outside circumference of the unit as a whole has not changed and has not gotten any larger. The radius from wheel center to tire tread edge is still the same.
Because of this, the wheels are rotating the same circumference, which keeps the speedometer and odometer reading correctly.
If you were to take a tape measure and measure around the outside of the old tire, it would be almost identical to the distance measured around the outside of the new tire.
Because the metal part is now bigger, the rubber part is now smaller.
The wheel will rotate just as it did before.
Because the new wheels are now an aluminum alloy and there is physically less rubber for the tire, the overall total weight of the new wheel and tire is less weight than that of the orrigional overall weight of the orrigional stock steel wheel and tire.

The circumference is the same and the total weight is less.
Therefore, there is less power lost due to the weight of the wheels.

Yeah i understand that too.. but still there is more weight towards the outside with a bigger rim.. your still probably did gain hp to the wheels though since its only an inch bigger
