Default Any Disadvantage to Running Wider Tires up Front. 265s or greater

I understand that there is less understeer with a wider tire up front, but does steering feel, turn-in or agility suffer?

I'm looking to put 265 or 275s up front.

Many seem to be happy with these tire sizes up front, yet I've been told by a few others that the car doesn't feel as "crisp" or "agile" with these sizes up front.

A square setup may be ideal on the track, but just wondering if a typical 245 or 255 up front would be more street-friendly.

Thanks for your input.

i am currently running a 245 and will be running a square setup very soon (275). the only disadvantages i could think of is the car following the groves on highways and hydroplaining will be increased because of the the wider stance. granted i do not drive the car in bad weather, the hydroplaining is of no problem to me and i can deal with the car following the highway grooves. i personally feel for my driving style, the pros out weigh the cons in this one

I had Michelin ps2 265/35/19 on my 19x9.5 before and they resulted in very heavy steering. Lots of grip and gave good amount of rubber upfront but looking back at it now, I don't think I will need to go that wide upfront anymore.

I currently have Vredestein 255/35/19 which feels very good when steering. Light but confident in steering.

I run a 265/30/19 front, 285/30/19 rear - steering is not at all heavy, and turn in response is fantastic - better than it was with my previous 245/40/18, 275/40/18 setup. When I had the NISMO front lower control arm bushings fit, combined with the Moonface RCA kit and had the car cornerbalanced (all done last fall), turn in response improved noticeably.

Remember, it's not a zero sum game. Everything has to be taken into consideration, from spring rate, to tire pressure, the specific tire, swaybar type and settings, alignment settings, offset, integrity of the bushings, etc. All of these together determine overall feel. The only way to know for you is to buy it and try it. You have to be willing to take a given set of parts and play with them in a variety of conditions, altering those things you can alter, taking notes, etc over an extended period of time. Only then can you really determine if its working properly for you or not. It can take some $, and take some time, but it is very rewarding.

As far as track setups, again, it will vary. What is 'ideal' for one person, can be horrendous for others. I've tried square setups on my own car, and didn't like how the car behaved. I vastly preferred a staggered setup. Others will prefer a square setup - whatever you are more comfortable with and quicker with, is the ideal setup.

^ the man speaks truth.

It's about setting up your suspension correct.
I have run square setups before and liked it
I still had a hint of understeer and working to
eliminate this.

Corner balancing and know what each individual adjustment
in your suspension will affect and how they interact with other
suspension components is paramount.

Well put. I actually really like our 265/35/19 PS2 up front. We ran a 275/30/19 up front for a while - I only changed because I wanted to change to a PS2, but couldn't easily find out in the 275/30 size. I think if you cheap out on tires, the larger tire (and most likely taller sidewall) may make the front feel "heavy".

Is your tire size smaller diameter than stock?

And the front suspension adjustablity you have most drivers don't. That is an important difference between your and most people's setups and should be taken into consideration.

My front suspension is nothing fancy - coilovers with adjustable a arms. Tons of people have these setups

Smaller that which stock? Smaller than my 04 enthusiast tires were? Yes...by a small amount. Smaller than the 04 Track came with standard? No, it's slightly bigger. Overall circumference is not important to me - contact patch + front/back stagger is

I have 265/30/19s up front as well and the steering is heavier but not terrible by any means. I prefer it. Car feels considerably more "agile" than stock, but again I also have a-arms, coilovers, sways, etc.

the roll center adjusters probably make a difference in feel as well.

absolutely did, steering got a bit lighter when I had them fitted, and I love the feeling that they gave, but it was never heavy to begin with...at least not noticeably so

I got a question, is a 10" wide wheel upfront overkill? I am thinking of running a 19x10 +20 all around.

the reason why i say hydroplaining will increase is because the psi of ground force is spread out throughout a wider tire and will act more like a wide padel istead of splicing through the water with a skinnier tire which will have more psi of ground force because the weight will not be spread throughout a wider tire. This is why winter tires are usually recomended to be some what skinny tread widths.

"Overkill" in what respect? What size tire do you want to put on it?

265 front 285 rear. Overkill meaning will it affect steering with such a wide wheel in front?
