No, he's not.

A half inch is HUGE.

There is no need for a tire that tall, especially when all ya gotta do is get a smaller profile.

I thought the 1/2" was off too... So I ran calculations.

Diameter
205/55/16 (stock size) - 24.87
265/40/17 - 25.34
275/40/17 - 25.66

The 265 is better but still not ideal. Any particular reason you are set on those sizes?

height is gonna be different depending on the tire

the 'size' of the tire is not always the same as you think it is......until you measure it it isnt really known

and going that big is moving a LOT of mass farther away from the axis of rotation and it will make the car sluggish

thinking that ya need big, dumb, heavy wheels and tires is doin it wrong

The stock 2011+ wrx tire height is already a bit tall for the gearing.

That's why I am trying to stay as close to the height of the 235/45 as I can. The 265 is about the same.

I am going with one of the lightest wheels out there (rpf1) which I am sure is lighter then the stock 17x8 and just adding an inch to the width. the 265 should not be that mich heavier then the 235. So if anything it may be a bit lighter or right around the same weight

i dont think you understand what is actually going on

and if you did your suspension properly, you wouldnt need such overlarge tires and you would gain lots of perfoemance by NOT going to a too big a tire

you are wanting to do it wrong...and for all the wrong reasons, im sure

a 255/40 is PLENTY of tire and a LOT lighter than a 275 will be

stop trying to look all race car and **** and edit that k00ness from your thought process and ya be better off

http://www.federaltire.com/en/images...1233035187.pdf

275 is only roughly 2.4# heavier than 255

and 5# heavier than 235/45 (stock)

235/40 from federal is actually heavier

First of all, I am not trying to be all race car and ****, I am not trying to go for way bigger look, I am trying to get a tire that is the same height as the stock 235, and that fits correctly on a 9 inch wheel (I ain't trying to go the stretched look) and being I am going to purchase a higher end tire (not no federal or nexen pos) I am sure the weight will be fine.

This post really shows how little you know. 255's that scotty suggested aint stretched on a 9" tire, and if you get a wider fitting tire (such as a federal or star spec) itll give you the width you want while keeping sidewall height where you want it. As i mentioned, the stock 2011 tires are already too tall for the gearing.

Federals are fiving awesome tires, an it has nothing to do with cost. In fact, I don't know of any other tire manufacturer whose CEO holds a current F1 lisence.....

Lol I was just giving you some examples of weight difference. Get off your high horse, bud.

and federal is probably just as good as what you are thinking is "higher end"

Such as? I'd be curious to know - I've heard some people have had experiences of them chunking during track use but nothing other than that.
