So, it sounds like the 305's aren't taller, just wider, right? Anyone know the equation to convert them into inches? Isnt like 305/50 plus the rim diameter for overall height?
I wouldn't mind getting something a hair wider to make it sit a little more substantial, but nothing that'll require fender flares.
Also, I got the 2" level kit because I hated the stock nose dive look.

1. take the first number (the width in millimeters) and divide by 25.4, this give you the width in inches
2. multiply be the second number (aspect ratio) divide by 100 (percentage), this gives you the sidewall height
3. multiply by 2, the add the 3rd number (wheel diameter)
Example: 275/60 R20 (factory 20" Ram tires)
1. 275/25.4= 10.82677 inches
2. 10.82677*60/100 or 10.82677/.6 = 6.496 inches
3. 6.496*2 = 12.992 + 20 = 32.992 = 33" tire height.

had 305/50/20 toyos on my 05 ram. they are 32"tall and 12.5" wide. the wider tire handles much better on dry roads and fills out wheel well nice. didnt run the tires in the winter. had them on aftermarket wheels so not sure if they will rub with stock wheels.
