trying to decide if i should buy Nitto NT555R 285/40ZR18 to replace my Continental DW Extreme contact 275/40r18
Nitto says will fit a 9.5 wide rim and my 2007 SVT GT500 rim's spec says 9.5
Helmet is purchased but need local mechanic to do inspection..cant wait until May 6th
The '555R is a drag radial, isn't it?. Most land speed guys doing the Texas Mile are using more handling-oriented tires. I've heard of people using Hoosier A7 autocross tires even.
The Continentals are Y rated so it will be good to 186mph as opposed to a Z rated tire which is rated for 149+mph, if that matters. I've never run a 1/2 mile event so I don't know how crucial launching traction is, but I don't think it's worth the hassle of switching to stickier tires if your current tires are decent enough.
Either way a 285 width tire will fit the GT500 wheels just fine. 285/40 is a OEM GT500 size, IIRC.

R7 is what most of the serious cars run, they hold the heat better. 555r will be more than ok for the speeds he's trying to hit but I think the Conti DW would be better as well.
Best of luck on your run. Weather will be perfect!!! Highs in the 60's with a crisp breeze. Let us know your numbers.
Nice runs!!!
You getting any hood flutter?
Glad you had a good time and returned safe and with no breakage- what was your set up again - didn't you add a blower this winter to the car?
