I have 305/40/22's 4.8 and 3:23's I have heard of losing gas milage then I have heard of gaining milage because of the tire size.Oh this is when switching to 4:10's. Please help I believe I'm going to switch either way but I would like to know.

Bump
Going with a set of 4.10 gears will help out a lot. City mpgs will get probably 2-3 better because your main enemy is the ECSB 4.8 with 22" rims. With 4.10s, your motor and drivetrain won't have to work as hard to get the pig rolling. Hwy mpgs will either stay the same or get slightly (1 mpg) worse. I would recommend going to 4.10s. If 4.10s seem a bit to high for your needs, you could always get a set of 3.90 Yukon gears...
Thanx now I can show this to my dad for proof and 4:10's are on the way!!!:)
yeah if he doesnt buy it then break his hip
Shut I wish he would buy it, he makes me buy all the parts performancce wise but he still has to ok it.:(
Pffff. If I have the money for it I buy it. The only exception was the '02 WS6. I would have been kicked out of the house if I came home with a TA with straight pipes.
I replaced the 3.42's with 4.10's in my '99 Z28. Went from 29 MPG hwy to 24 MPG hwy, but got me into the high 11's.
3.73s seem like they would be a happy medium. That's what I want to go with when I start school this year and can get it done for free.
3.73's in my truck, 19.8 MPG when N/A on the highway.
Got me beat. My city/highway average is 16 or 17 with a 4.3 with cold air intake, flowmaster, all synthetics, and the tb mod.
You need more torque. I suggest a 6.0.
samething happen to a friend here, hit him from 22 down to 18 mpg hwy, pay to playQuote:

Don't forget the s/c LS9 if money were no object. :laugh:
If money was no object I guess I could go with a twin turbo 572.... or just have two 4.3 engines in line with the 2nd in the bed. You have to admit that a sc 4.4 liter Northstar would be unique... and with 469 horsepower it would embarass just about any 5.3 or 6.0 I passed.
Talk about being able to pass everything but a gas station :laugh:Quote:
