Hi,

Has anyone run 245/275 setup?

I need to get some rears. Was considering going to 255/275 - whilst I understand that many people are ok with this, I have seen posts where some say they lose a bit of steering sharpness going to 255 in the front.

So was thinking that a 245/275 setup would keep steering as it is, but give a bit of extra rear grip, however, I guess that there is a risk of that it may start understeering.

Any thoughts/experience on this appreciated.

Thanks.

I don't have experience with running 30mm difference between front and rear.

But I have experience with running square 245 winter set and the difference is quite noticeable.

I also have experience with running more aggressive alignment (0 toe front, half of the OEM toe rear). That is also very noticeable.

So based one that I would say it doesn't matter which tire you run at the front. Try it and if you don't like it then change the alignment.

Also depends on how your aero is set up. If you have a front lip you might be okay.

I'm running 255/275 and I noticed when I installed my front lip the car now has a very slight tendency to oversteer (vs. slight tendency to understeer) at the limit, which is fine as I can control the car with the throttle and my front tires aren't so beat up after heavy driving. I'd imagine if I went to 245 in front it'd probably go back to neutral or very slight understeer again.

Thanks for letting me know re that. I may get a front skirt in future, so great to know the potential impact.

I have decided not to risk understeer and have ordered a 255/275 set of PS4S which will go on at the end of the week.
