Rear rire size

[DriftersWay]

I'm about to purchase a new rear tire for my 14 RT-L
Going with the General Altimax RT-43
I saw someone post a size that would compensate for speedo
I believe it was a 215/55 R15.
Can anyone tell me if this is right or not.

Thanks

You have a Limited. Just check the new tire with your GPS against the speedometer and you'll know.

I just put a 205/50 r15 on the back of my 2013 RT. Checked it against the GPS and :spyder2: is going 2 mph faster than GPS....to me that's no big deal....

Use a 215/60/15. I am using it on my RT and it works well with no problems and fixes the speedo error.

OEM is 225/50-15

The typical size used to correct for speedometer error is 215/60-15
The 215/55-15 should bring you to within about 1 mph of what your GPS reads...

And....
205/55-15 is just about the same overall diameter as the OEM size.

Thanks All.

215/60/15 will put the speedometer right on with the GPS with no worries.
