I've done a lot of research and it seems that in order for me to correctly run NON-oem tires on my 2000 s2k, i should run this tire fitment: FRONT: 205/55/16 REAR: 245/45/16

However, I've seen an s2k with oem 16 inch rims running 225 tires in the front. Would it be alright to run a 225/245 setup, or will there be a negative impact on the handling and performance?

I'm an aggressive driver, and I'm trying to obtain peak performance/handling using my stock rims. I'm curious if running 205 in the front is better for my type of driving, or if 225 in the fronts is better than 205.

Thanks anyone for the help.

 

the question you would have to ask is.. what are you trying to do?

because going to a 225/245 setup will increase your overall grip, but it will also introduce some oversteer.

 

i'm trying to obtain the best handling possible, meaning harder cornering, less oversteering to reduce chances of spinning out.

How come a 225/245 setup would introduce oversteer? Wouldn't the increase in overall grip cause the s2k to reduce the oversteering?

 

A wider tire up front will increased grip on that end of the car therefore increasing your potential to oversteer.

I don't believe that you would have issues with this setup if you were to run a front anti sway bar. You may also be able to get away with this setup if you increase your negative camber in the rear and run 1/4 or so toe in in the rear.

I would say that if you are not familiar with how certain changes affect a vehicle's handling that you should stay with the stock stagger and run a couple high performance driving events.

 

well, it seems we have mixed opinions of the best handling possible. i would like less understeer on my car personally.

so, if you're trying to get more cornering speed, while keeping oversteer out of your way, a 225/245 tire setup with a comptech adjustable bar would probably be the best bet.

however, and don't take this offensive. . i would say the one thing you need right now is either some time on a track, autocross, or with an instructor at a hpde. the s2000 in stock form is very neutral and if you pay enough attention to it, the car will only do what you ask it to. i found this out over time with my car.

i was having trouble with oversteer when i first got mine, however i'm to the point now where i can go into a turn and decide what i want the car to do, understeer, oversteer or a nice 4 wheel slide. .or nothing at all

 

hmm.. thanks for the detail. I'm actually running around 1.5 to 2 degrees of camber in the rear, the car is dropped an inch all around using tein RA coils. I'm just wondering if more people recommend using 205 in the front rather than 225, or if there's hardly a difference.

 

225's on a 16 inch rim up front? I wouldn't recommend it. Too much tire and not enough rim width for optimum handling.

Weak sidewalls during hard cornering.

Get a set of OEM 17's and run the 225f/255r setup or stick with the OEM 17" setup.

Regardless, if you go wider up front with the 225's and stay stock on the rear width...you are going to induce oversteer. It's an equation, once you change once side of the equation you better change the other or else it's not going to equal out. Your handling and performance will suffer at the limits.

If you understand "plus sizing" then you can modify from there to fit your driving style and preference... ie camber, toe, tire size, rim width, offsets, etc.

JMO.

Stock tire widths on the stock rims.

Go larger on the wheels and tires if you feel the need for more tire.

I've driven a friend's R comp-shod S2K at autocrosses a few times and he has 225's on stock 16" wheels up front. The overal grip is higher (most likely just due to the tire composition), but the feel is completely gone. Turn in takes about 3 seconds as the tires decide what they feel like doing.

S2Kpuppy, if you are terminally understeering in turns and your car is set up properly, you are probably entering the turn to hot or just plain getting on the gas too soon.

AP2-2NV, how would a 225/245 FR with an ajustable anti-roll bar be the best possible option?

 

for every day use i have the larger size on mine, when i went to buy tires all they had was the 225/17's. the car seems more stable now and has a better turnin. i like the outcome. pirelli p0/neros.

 

well, i would say it would be a good option until you brought up the fact of the wheel width, forgot the ap1 wheels are thinner than the ap2's.

but, i would say that's a good option because you get more overall grip but can tune out some of the oversteer.
