Drag Radial Question

I did a search but couldn't find anything conclusive...

What BFG Drag Radial tire size would be best to run on the OEM E55 18" wheel (drag strip only)?:

265/40 R18
-- 26 lbs.
-- Diameter 26.2"
-- Width 9.5"

275/35 R18
-- 27 lbs.
-- Diameter 25.6"
-- Width 9.5"

295/35 R18
-- 29 lbs.
-- Diameter 26.2"
-- Width 10"

I don't think the additional 3 mm of sidewall on the 265 would give you an advantage over the 295/35, especially since you're getting 30mm in width with the 295. If the 295 fits, I would use that. I have 315 Nittos on my F-body and when new, they hook up like a mad dog.

Does anyone know if the 295/35/18 will fit?

Not sure the "best" but 275/35 R18 are the ones I ran at the track with no problems. Big D-FSU ran those too, before the MT's of course.

i too was noting the diameter.. if you can get traction, the smaller diameter is effectively like dropping your diff ratio a little bit, while small can help your 60ft time if traction permits, and will help the car rev out a little quicker. Not sure if the difference is that significant, but by the end of the track it may pay off...
