I’m looking at getting some Rocket Racing wheels made for the challengers. Mine is an 09 SRT 8. 20x9 front 20x10’s on back. I just got this car so I just started research what tires fit on these cars. I came across something about the cruise control not working if you run a little shorter tire on the front. Is this a real thing? Do I need to keep the tire height as close to the same as I can? I was looking to do a 275 on front and 295 out back. By my research that seems to be doable. Any opinions on experiences with those sizes or any others are wanted...thanks!

To keep your tire diameters as close as possible, you should buy a 275/40-20 for the front and a 295/35-20 for the rear. The 275 has a 28.7" diameter and the 295 has a 28.1" diameter.

That was the plan. Try to keep it close to the factory tire height front and back. So to not mess up the speedo and have to have it reprogrammed.
