Going to try 26" tire insted of 28".
I am running a 275-60-15 M/T DR right now and it is working good but I want to try a 26" tire and see if it will bring my 60' down any if I can get it to hook. I have a set of 26-11.5-15 M/T ET-Streets that are almost new and want to give them a try but I have a few questions and want your opinions.
1) the car is 60'ing 1.50 right now with a best of 1.47 on the 275-60-15s do you think I will get the 26"s to hook at all?
2) We have an 1/8th mile we run here and the cars best pass is a 6.72 @ 106mph, if it will hook will I see any difference?
3) how much will it change my shift points?

Here is what I have always been told (I know very little about playing with tire sizes and what not)..
A taller tire such as a 28" will 60' worse but let you pull better up top..
A short tire such as a 26" will 60' better but hinder up top.
Reason being is because it doesn't take as long for the 26" to start its rotation but once it does it has to spin more to get you the same distance.. Hope that made sense..
Of course this theory is taking in that you can dead hook on the 26" and the 28".. I always thought you stayed with the smallest tire possible until you couldn't hook anymore and then you moved up.
I am on a 26X10-15 Hoosier slick right now.. I am in the 1.47-1.50 range on motor and have not sprayed it yet, sure I will dead hook even on the spray.. I run 1/8 mile. Race weight is 3500 or so.

I 60' amazing for my power levels I suppose.. I only put down 375... Although on a normal dyno it would be around 400-410, but for its weight and power level I think it does well above average..
I am just wondering if I would benefit with any other tire granted traction with all sizes on hand.

This is the way I thought it worked and I went with 3.73 gears and a 28" tire and now I am wondering if I should have went with 3.90's or 4.11's with the 28" tire. This is the main reason for trying this to see how the car reacts with a little more gear the cheep way.

I think the point ER was trying to make was that although stock eliminator cars are very limited, due to rules, in making power they still 60' VERY well in order to get the most out of the cars.
Alot of SE guys run 30x9" tires and I followed their blueprint as far as suspension goes with my own car. My car makes more power than a SE car so I used a slightley wider tire but the same concept applies, IMO, up to around mid 9's (N/A of course).
That concept is to get good weight transfer with little resistance and you do that with a tall, thinner tire (and with alot of other stuff).
I've seen SE cars on a hot day 60 in the mid 1.3's while only turning a low 11 sec 1/4 mile and YOU CAN DO IT TO with simple stock style replacement components and some chassis stiffening (subrames, 6 pt etc.)
OP, I have no doubt you will after your very 1st track outing with a set of 26"ers

The RPM threw the traps is what determines my tires. Rule of thumb is go as tall as possible while not dropping the RPMs to low or shifting into OD crossing the line. Both kill ET.
You want to be at the limiter crossing the traps. Gearing also plays a big part in this.

I'm from the club that says go with more tire than you need (particularly in a bracket race), and match the tire / redline via the appropriate gear.
If you run tire limited class guess you can't go w/ more tire than you need.
I love watching these big tire cars that run in the 10's with open headers. I think to myself "what a waste".
