1/2 mile time for tire size change

[3rdcoastmrauder]

anyone know the stock 1/2 mile time for rauders w/ 255/55/18s on the back?

I have no idea what you are talking about :confused:

If you are referring to revs/mile, then the value is anywhere from 694-705, depending on where you look.
Just set it at 695 (like I do) and it will be fine.

sorry (drunk while posting) what i mean is that without any other mods what is the 1/2 mile time (not revs/mile) for a bone stock marauder running 255/55/18 size tires instead of the stock 245's on the back. I noticed a slight (seat of the pants) slowing of my rauder after I got the new tires put on (even with a re-tune) and I'm trying to get an idea of what she'll run in a 1/2. im guessing like 15.7 or something along those lines but I was curious if anyone had any concrete proof

o yea

If you have stock 3.55 gears going to a 255/55-18 tire will give you an effective rear gear ratio of about 3.50. If you feel that your going slower then you need to get more mods lol. Get some 4.10 gears to help correct the problem which will give you an effective rear gear ratio of about 4.04 with 255/55-18 size tires.

Honestly if you just have a tune, there shouldnt be any real difference in time, larger tire equals larger contact area to help you launch better off the line. Are you sure you that it's a 1/2 mile or is it 1/4 mile time that you want to find out?

You must mean 1/4 mile bescause if you figure on doing 15.7 in a 1/2 mile you will have one hack of a fast 1/4 Marauder.

P.S. - Pass the JB this way! :D
