I have 18" rims with the Nitto NT05R 305/45R18 with a 28.9 inch diameter that I used for drag racing my 2010 RT Classic. The question I have is that some have speculated that if I don't have the tire pressure sensors in the rim it will cause the Hellcat to bog done or cause electronic issues. Now with my 2010 I had an interceptor gauge pod that allowed my turn off traction control and outside of my tire light showing on the dash it caused me no bogging issues.
The stock tires look like they measures i at 28.66"
So without having a tuner the variance is;
Revolutions per mile (km) 700.11 (435.03) for the 305/45/R18 compared to stock 703.67 (437.24) 3.56 (2.21) which is less than 0.5%.
I know with my stock tires on my RT of 245/45/20 the car would go into limp mode as the revolutions did not match or was outside of tolerance.
With the stock tires being a 275 and the Nitto's in a 305 I'm as close as I'm going to get.
With the new Hellcat is this an issue?
