You are certainly on the right track. Those Nitto drag radials in size 245/50-16 are at 25.67 inches tall (inflated tire diameter).
Just as a note: the 275/50-15's which I see everyone purchasing are 25.75 inches inflated overall diameter.
*I expect later this summer the Nitto DR 275/60-15's will be out and they are ....get this....27.76 inches tall, inflated diameter!!
**ALSO, just some advice, don't give up on those Nittos just yet. There are some FAST cars running on these exact same tire but there is a "cushion" to use them. Follow these guidelines and you might have better luck.
Nitto company advice on drag radials:
To get the most out of your drag radials, we recommend doing a mild burnout to properly heat the tires. The most important thing to remember is that the optimum operating temperature for the drag radial is **100 degrees Fahrenheit**.
>>LSM note: believe me when I say there are people running 8's and 9's and they make sure to use a infrared pyrometer when
running these tires for contigency (Rebco makes one, $204.99 through ME).
The optimum inflation pressure varies per application. We recommend starting at 20 psi and then tuning it from there. Be sure to never drop below 15 psi, or exceed the maximum inflation pressure.
The NT555R does not have a break-in procedure, and does not need to be heat cycled. You can put them on and go straight to the track!
