Which M/T would you keep?

[TheWizard]

I have two sets of M/T ET Streets.
I have a set of 26x11.5x17 M/T ET Street slicks on 17" bullets.
Best 60' on stock suspension is 1.94 with 130 degree track temp.(hot!)
I've been happy with this same tire on my old 07', but I picked up a set of 275x60x15 ET Street Radials with 15x10 Race Stars. (I know relo's req.)
I have never been down the track with the Street Radials so I don't know how they would be any better. I'm also concerned with a 26" tire vs a 28" tire on my ET (12.38@113 best).
I have someone who wants to buy my 26" tires.
Do I let the 17's go and keep the 15's.
Do I offer him the 15's and just keep the 17's? IDK?

Suggestions?

Are you a auto or manual?
What gear do you have?

 

[TheWizard]

Auto with 3.73's

My vote is to keep the 28's.

I think 28's are too tall, but I would keep the 15's if you track quite often.

These would be track only tires.

IMO the 26" tires will be better for your power level unless you have very short gears.
