285/35-19 rear would probably work fine with that front.

Why do you want so much tire? That's my question, is there a goal or a purpose? Or just because? Just curious.

How is someone giving advice on a subject they are confused about helpful in any way? You're still missing it...the aspect ratio measures the ratio of sidewall height to width. A wider tire with the same aspect ratio will result in a wider sidewall and taller diameter.

I think both sides are confused mainly due to the OP!

I fault the OP in this one!

OP are you still at stock height? Is this on the stock wheels? Endly is this for looks or performance?

Like I stated, a 305/30/19 has a SMALLER side wall than the stock 265/35/19 and he wanted to go with a 265/40/18 up front, causing his front wheels/tires (as a whole) to be taller then the rears. I have a great idea, since you are the expert here, how about you give him some of your advice? I'm sure we ALL could learn so much from you!

285/40/19: Actual speed 100.0 MPH. Speedometer will read 94.02 MPH.

I can provide you with the tools to make a proper tire selection, but if you do not use them I may as well be talking to a brick wall.

please don't make me figure things out

just suggest something with good backup lol

I'm planning both autocross and some track time during summer and I talk to one of my

friend and he told to to stay with same section height.

so my final decision is to stay with 265/40/18 on the front and get a set of 285/40/19 in

the rear.

response please and thanks
