Goodyear Eagle F1 GS-D3's

It might be just my case that I can't feel a difference, I don't know. However see it from my point of view...I'm going from Toyo Proxes 4's with 225 rears (the improper size because my tire place is stupid) on my 16s for winter to Summer Only Eagle F1s with a much larger footprint. So no matter what size my 18" tires are, they'll always feel better

 

I don't know about the S, but on my miata, which was a bigger jump (14" to 18") The 18's made my car feel slower than before it was turbo.
They sucked so much ass. I'm not sure of the model or weight, but they were BSA 5 spoke wheels. I drove it for a week like that, switched back to my stock wheels, and it felt so much better.

Apples to Oranges, but I'll never buy bigger than 17" rims ever again.
Even those will be the lightest I can find.

 

Your 0-60 will be slower, your top end, and highway rolling would be slightly faster.

 

Diameter, weight, and weight distribution of the wheels effect acceleration. By getting a taller diameter wheel/tire setup [some taller wheels may have skinnier/lower profile tires which negate this] you are doing the opposite of what many people here do by 'upgrading' their 'gears'.

People spend thousands on lightweight wheels for racing. It makes a difference. Whether you can feel it or not doesn't contribute to whether a difference is actually made. But if the feel of the car is more important to you than actual performance, bigger diameter wheel/tire setups may not matter to you.

An identicle wheel/tire setup weight wise but is taller will require more force to rotate. Make that wheel/tire setup heavier and taller, the force required is magnified moreso.

If you are aren't they type of guy to get gears and like the looks of bigger wheels, 18's or whatever will probably be a good addition to your car. This is a car based on performance and I think adding 18" wheels to an already torque deficient car is not logical, especially when most pay well over a thousand dollars to degrade it in that manner. However, we all own our cars for different reasons. Some racecars do get bigger wheels because of traction issues, but this is not typical for s2000's.

 

Incorrect, but it's a typical assumption. Taller gearing decreases ALL accleration in all situations. Feel free to do some research on the gears topic here, it's a popular belief but unfounded.

The only way it would 'help' your top end is if you had the power to redline the final gear, which no n/a s2000 on near to stock gear ratios has. The taller gearing provided by the wheels would enable you to obtain a few mph greater mechanically.

Adding taller wheels could help your gas mileage slightly in top gear at cruising speeds proportionally to your decrease in acceleration caused by having the lower revs.

 

You are correct....I meant at the end of 6th, but we dont have the power to do that (only down a hill).....
