01 Silverado

[fumble]

I know this topic has been covered many times, but I can't seem to find an answer to my question. I went from 245/75/16 to 265/75/16.

 

Did any of you notice that there was a loss of "Gitty up" when you get on the pedal? I just feel like the truck is doggin now! Will this change when I get the speedo recalibrated?

 

Any help would be greatly appreciated.

 

Thanks,

 

Dan

You increased the tire size and increased it's rotating mass, so of course you are going to lose some accelleration and decelleration.

 

Typically when you jump to a bigger tire size you change out the rear end gear and install larger brakes. a 245 to a 265 swap doesn't seem like that big of a change, maybe it just seems like it has lost some of it's oomph

A tune will straighten out your speedo/odometer calibration and restore a bit of lost power...But gears are what's really going to help.

It currently has 4.10 rearend. What would be optimal?

[Wingnut]

I'd say that those gears are perfect. I'd kill for 4:10 gears in my 2wd with 265/75/16's

With 4.10s thats about as good as you'll get with that setup. I went from 265 to 285 and it was very noticeable (I only have 3.73 gears).

I have 265's with 3.73's and my new gear ratio is something like 3.56 I believe.

It has to be in your head. You are only 1.18 inches taller.

Original tire

245x.75x2 Divide by 25.4=14.7+16=30.47inches

New tire

265x.75x2 Divide by 25.4=15.65+16=31.65inches

Probably is! When I had the Jeep, everytime I did a mod, it seemed like something was right as soon as I got in!

if the old tires were p245 and the new tires are lt265s they will wiegh quite a bit more, more plys=more wieght.

i went from p245s to bfg lt285s w/4.10 and could tell the difference right away.

that's not necessarily the case ... although they say they are 265 the actual diameter of the tire varies from manufacturer ... if you look up the specs it will tell you. just in the 265 size it can vary by as much as an inch
