bigger tire size on stock wheels?

I was wondering if i could put 245/35/19 tires on the front stock wheels, considering i have stock 305/30/19 in rear.

Worried about burning the differential.

Also would this benefit the handling?

Check out this thread here:

Has some very interesting info and a link to an online tire size calculator.

Also, PM Daemon at Tirerack. Knows his stuff.

Hope this helps.

thanks bro. According to the calculator it will be less than 1.5% change.

My question is tho, how will understeer/oversteer be affected? As well as the drive of the car.

Additionally will it rub? I ahve 7mm spacers infront with H&R springs

noo i was thinking 245 upfront to reduce understeer and make heavier steering

just concerned about rubbing because i am lowered with h&r springs as well as 7mm spacers upfront

I ran (I believe) that size when I went to PS Cups. I went through two sets of cups without any damage but it would lunge back and forth at low speed engine braking. The dealer was on about some issue of the PCM miscalculating the rotations of front and rear wheels in relation. I didn't believe them until I went back to stock PS2s and the problem stopped.

A 1.5% difference won't get anywhere near burning out the differential. It's a slow grind for the rare instances your differential is actually supposed to be static. Much like your front and rear diffs, the center one is always giving, and a slight diameter change won't exacerbate that much. But there might be some other symptoms.
