I will be buying a reg cab soon and making it into as much of a street/strip beast as much as I possibly can. I am looking into how to lighten everything as much as possible and which on the rim and tire side of things it looks like the only weight savings can really be had in the rim. With still having a daily driveable tire it only varies a couple pounds from a R17 to an R20 (only sizes that have 275 or above width), but theres a 9 to 10 lbs difference in some rims but all I find for an R17 rim is a 30" tall tire so I would probably have to change to 3.42 gears. The basic questions I have are:
1. If I did the 17's with the 30" tire would it be worth it to to change the gearing and have the weight savings?
2. With a 30" tire and 3.42's I would likely end the pass in 5th which is past the 1:1 ratio so will that be a major downfall?
3. With having a smaller diameter tire will I be able to cut better 60's and just overall get going faster?
4. For the R17 tire the widest is 275, so would I would I be better off sticking with an R20 tire for the 305 and extra contact area, or have the rotational weight savings on the R17?
5. Is the look of having that small of a tire on a such a big truck enough to not even want to do it at all?
I plan to get deep into the 11's which from what I've seen shouldn't go past 130mph so i would be topping out 5th on a 30" tire and 3.42's.
