Default tire sizing

ive tried some different combos and i need some input....

cars setup
stock 99 heads, intake and tb and shortblock
232/234 cam on a 112
basic boltons etc
150 shot of gas
built 4l60e tranny with 3600 stall with a 2.2 str
ford 9 inch rear with 3.70 gear 35 spline axles and posi
kmember and arms
qa1s up front
comp eng shocks out back
shohn tq arm at -2, lcas and panhard
lil weight reduction

well.... ive had a 275-50-15 mt radial on the car...hooked great on motor and sometimes on the gas....

now i have a 275-60-15 mt dr on the car and it hooks like a **** but it knocks the breath outta it on the topend....3rd gear feels like a brick wall....

both of these tires are 11.5 inches wide....

what bout going to to the 255-60-15 which is a 27 x 10.5??


Or.....keep the 275/60s and put a 3.89 gear or a 4.11 instead of the 3.70?

as for 60 ft times...on the 26s it went a 1.46...average high 1.4x on gas (when it hooked).....now on 28s its 1.50-1.54s

what do you guys recommend??

Keep the tall tire, put a little gear in it.

I'm having the same issues Dabe. I'm running 27/10.5 ET Streets right now with a 150 shot out of the hole. My best 60' so far is like 1.58 (3.90 gear), but I have stock shocks and springs, and all my runs are down at 'Nam, which doesn't hook for **** in the first place.
