Hey I just replace my rear tires with 245-45-16 kuhmos but my front have the bridgestone oem tire but in good condition 225-50-16, I was wondering if my handling go affected by using two different size tire? thanks

Yep

JoeD

good answer.

technicallly, you will understeer a little more with a wider tire in the rear.

I doubt it would understeer with those slippery Kumhos on the back, even with the extra 20 mm of width. I'd be watching out for oversteer.

JoeD

did you not see the "technically" in my post??

SleepR1

You're both right!

can u explain understeer a little more to me please? thanks

JoeD

understeer is when the front end plows or pushes. the opposite of oversteer, when the back end swings out.

this is caused by inadequate front end grip, or overwhelming grip in the rear.

I have kumhos all around 265 in the rear and 240 up front. JoeD is right, it should have more understeer, but in practice the rear end feels more loose. Also the kumhos scream bloody murder when you nail the throttle. Just the same-what a bargain. $600 for the whole set.

erm, which khumos did you get? Some of them aren't exactly what I would call slippery. Hell, you can get a set of R compound khumo's from tire rack for $600
