i was wondering if my 60fts would improve with a shorter tire height,88 dakota 3340# 418cid, 9.7 compression, pump gas small block stroker,about 470 hp,driven to the track, 727 reverse pattern lba tranny.ptc 10" converter, flashes 4200, 8 3/4 3.91 posi,stock front /rear shcks with cal/trac bars, m/t drag radial 295/65-15.1st time at track with new motor it ran 7.31@94.5 with a 1.64 60ft.im thinking about going to a m/t drag radial 275/60-15 or a 325-50-15 which are 28"tall instead of 30 like the current 295-65-15?i was thinking the tall tire was hurting my off the line gearing?

Yes, shorter tire will definitely help your 60 foot.I tried to go as small up front as possible without the car looking ridiculous.

Granted those are tall tires for your gear but better shocks would also help you
the shorter tire also reduces contact patch and may cause traction issues if the car is not set up well. so it could actually slow you down if you can't hook.

Also think of it this way... its cheaper to change a gear than it is to buy a set of tires.... tires about $450 and a gear and set up is $320 or less

I think your combo would be helped with a shorter tire BECAUSE the combo should have a taller gear in it.
BUT ... if the car is geared correctly .... I don't see how a shorter tire would help 60 foot times. Now reaction times ... that is another story.
