Tire Size Track Time?

[cj41foley]

How much of a difference at the track will I notice going from a stock tire to a 315/70. I know it will make a difference but how much? Maybe just add more power to make up the difference

what is the height difference?

[cj41foley]

32" stock vs 35" 315

it will give you more on the big end. it might help you on not spinning so bad. they can hurt you though, due to the weight and height

My 35's hurt me by about 0.5 -1.0 seconds in the 1/4 (estimated). If your 4wd, I would run stock tires at the track. Your able to spool and launch at nearly red-line b/c of the traction. Lauching in 2wd at anything over 1500rpms = no more rear tires and crappy times!!! LOL. I didn't goto 4wd on my first run and spun the tires through 1st and 2nd gear, 1/2 way down the track...cut a 18.989 at like 76 mph. 4wd ownes at the track!

You may lose alittle bit,but now you can launch at a higher rpm.

I would brake it up to 2100rpm's and run your tire pressure at 38-40psi.

I have 295's BFG's on my truck and I can pull 1.75..60's on NOS and 1.82's without so you will be fine.You just need to practice:burnout

well I'm only 2wd, thought if I could get them to fit the taller and wider tread might help me not spin to bad.

Sorry I wasn't paying attention that you are 2wd.
If you are pulling 1.89 with a 2wd that pretty dang good.
The taller and wider tire will help just play with tire pressure some to help with traction
