Gonna go from my 20" Tahoe LTZ aluminum 5 spoke wheels with 275/55/20 good years, and gonna put on the stock 17's steels with 245/70/17 tires on them.. How much time do u think I will drop in the quarter and how much weight if any? Royal purple 1/4 mile on Friday night if anyone is interested !!!

I'm hoping you meant to type 265/70/17. If so atleast .3-.4 but if they are 245 prolly none cuz ur gonna burn them off and them being so much shorter it won't shift right

For some reason my truck doesn't do spin those 20's Even with a stall ... I think that's asking too much for my little 8 lol.

Ya that is pretty narrow now that I think about it, but I'm gonna get it set for somewhere between my two tire sizes .. Well atleast propose that to my tuner .

It's a super cheap set on Craigslist for 260 wheels, sensors, and 85% tires

What stall do u have?!?! My old 4.8 with a 3200 would spin til I let off the skinny pedal!!!

I watched a bud drop 3/10's swapping to 17's.
My truck is running around on the same rock hard general 245/70/17's!
My truck didn't even think about spinning when i was there in November and it was 50*.

You should be fine if the track has decent prep!

Correct, I went from a 13.99 @100 to 13.55 @ 102.5 with better air and 17's. I would say its worth .3 forsure.

Good luck and keep us posted on the results.

It's a 3200, but it's pretty tight, it foot brakes up to 2800 or so ... I'm ready to get out and run her, I haven't ran it since I put the cam in, built the trans or stall, and now I'm puttin different tires and wheels. I'm hoping to take it easier on my components with less rotational mass.. Lol
