Exactly.. So wouldn't you want to be able to fit a larger drag tire back there? Assuming there is 1.25" of room to extend outward and inward, a 64 offset would allow for a 12" wide rim and extend the same distance inward and outward. I know there is room for that and probably with any tire too. I need to go measure the total distance from the fender to the inner areas. This will give an idea of the total width tire that can be achieved. Then I can chose a rim width that will fit that.

MT says the max recommended rim for the 275 Pro is 9.5"
I gonna talk to a few ultra and X275 guys and see what width they're using. I may go 11" or even 12"

Ya I guess Im just confused. 275/60 is not a very big tire at all.. I mean the ET streets I have now are 26x11.5 which translates to 295/60. And there's literally 2.5 to 3 inches of space around the tire. Especially towards the inner wheel well. I plan to go larger for sure. Im not totally sure yet, but Im thinking Ill be fitting a tire with a section width of around 13" maybe?? which will need a rim thats 11-12" wide?? I would assume..

Besides.. the ET "Street" was always a DOT street legal tire. Now its not while retaining the name ET Street. Not very well thought out in that area..
And anyone with a lowered vehicle will have to raise it back up to accept the 28.2" diameter.
Now I dont know about the compound in this one, but here is just an example of a 26" tall tire with 12" of actual tread on the ground that fits a 10" rim. Im just saying. There are a lot of options out there.

The taller the tire, the less effect the gears have. Ive heard its best to stay with a smaller diameter if possible.

Alrighty, Ive done a bit more research and found whats out there and the options. Its surprising how few sizes of tires there are to choose from in a certain diameter etc. for a given width rim. I realize now that a 10" rim accepts a pretty big tire when it comes to drag slicks, unlike street tires.
Here is my current choice for my next drag pack:
Wheels: Weld Alumastar 2.0 size 15"x10' rear and 15"x3.5" Front. http://weldracing.com/alumastar-series.html#6
Tires: MT ET Drag 26"x11.6" rear. http://www.summitracing.com/parts/mtt-3053
And Im thinking the 25x4.5 MT ET front runners. http://www.summitracing.com/parts/mtt-3001
Should be fine with 1" difference between the front and rear if I remember correctly?? Something about the TC system. Not that Id be using it anyway. There is a 24"x4.5" option in this front runner too.
Now heres where I have questions. I am trying to consider the correct backspace. I can choose either 7 or 8 inches for the rear rim. The stock wheels are 18x9.5 with a 7.5" backspace. So if Im doing the 10" wide and used the 7" back space, that would in effect push the tire outwards while deepening the dish?? And the 8" a little inwards (tucking the tires under towards the body)?? Am I on the right track, or do I have it backwards?

The 24" front is really short and looks funny. I would probably use the 25". Currently I have the 26", but next time I buy fronts, I'm going with 25". It'll help a little with R/T.
You are correct in your assessment of the back spacing. If you have flared rear quarters, get the 7" BS. I would think they'd stick out too far with stock quarters. I'm getting the RT-S at 15x10 and 7.5" BS.
Good luck. The 2.0 is a really cool looking wheel.

But then again, if I do the 8" it will allow for future growth in tire size without flaring the fenders. I just would like to have a little more of a deep dish look. They look a lot better that way. But of course, practicality is more important than looks..
