Hello,
I'm in the process of deciding on new wheels and tires. I've decided on staggered 18x10 and 18x9 black deep dish bullets.

I'm looking at getting them with Sumitomo High Performance HTR Z II Tire (255/45-18) on the front and Sumitomo High Performance HTR Z II Tire (275/40-18) on the rear.

My question is, will this give me roughly the same sidewall height that I have on my stock 07 fanblades? Anything else I should consider? The car will be lowered just slightly on Roush Rear Springs.
Also, for just over $1300 with TPMS sensors installed, is this a decent deal?
Thanks all!

i just ordered my staggerd fr500s black with nittos same front as you but 295/45/18

I had the stock 18" fanblades and went to 275/40/18's all around and only had to make a minor change with my tuner to adjust the speedometer. Without the adjustment, you're speedometer will read about 3.3 MPH too fast. Here's a link to a tire comparison website that'll give you the approx differences...

I went with the Sumitomo HTR ZII 275/40/18 and they are great tires. I put a picture up on american muscle. Red mustang on there with the steeda wheels under the sumitomo tires. There great tires, and a huge improvement over stock. Just remember there summer only specific tires.

As said all you have to do to change the speedometer is use a tuner and change revs per mile.

i went with kdw2 295/35 rear 255/40 front on 18s

if you don't have a tuner and are concerned about the 3+ MPH difference, the 45's will put you about 1 MPH faster than the stockers on the speedo.

WOW! I thought i was the only one with Sumitomo tires! I had those tires since Oct 08 and they haven't giving too many problems. Wear is minimal even though i drive over the speed limit most of the time.

Cool. Thanks everyone. I don't mind my speedo being off by 3 or so MPH but will my Odometer be affected? I don't want to mess with that...
Thanks again!

You got the fronts right.

But, you should get 285/40/18 on the rear wheels to match the stock overall diameter.
275/40 would be shorter than the fronts and it would look wrong IMO.

Now if you want to go for a better look, and that's what I did, consider getting 295/45.

Thats not a bad deal but like someone said go with 285/40 rears, thats what I have and they are exactly stock height so no speedo/odom problems.
