Need input on rim and drag radial combo

[DetailsUnlimited]

Should i get 17's or 18's, and i'm looking at MT drag radial II but which size? I know the bigger the better but not much to choose from. And also the weight factor! And maybe tire pressure. Getting ready for next year. have to plan my funds!
Thx

bigger is def. not always better... guys seem to like the 305/45/18 MT Drag Radial, I personally run some M&H DR's 275/55/16 on PYO's

My buddy is a direct dealer for MT and in the DRII the biggest size is the 305, which is a 33 inch tire? I think? There are not to many size to choose from, maybe a 28/29

305 is the width in millimeters, which is just under 12 inches. The second number is the height of the sidewall as a percentage of the width. For total height you have to double the sidewall height and add in the rim size. For Example:

My street tires are 305-50R20
305mm wide ~ 12 inches
50% of 12" = 6"
20" rim + 6" sidewall on each side = 32" tire
So my street tires are approximately 32" x 12"

The MT 28 x 11.5 ET Street cheater slicks for 16" rims work very well on these trucks up to about 125mph.
