Guys what would the ramifications of running 4.10s with 255/70r16s sized tires be. I need new tires, and was thinking about regearing in a year or so (I have a baby coming soon, so there will be no gear and DTT money for a bit). But when I do regear the tires will still probably be good, so I would probably have a year where I had both the 4.10s and the 255/70r16s. Any negative ramifications (transmission for example)? I know it would actually give me better acceleration and torque (which would be useful in D.C. traffic). Would it just run a little higher RPMs at highway speeds, and thus less mpgs on highway (but better in city)? |

255's are right on that borderline of wanting a regear, the saving grace of the 255's is generally they're P's and quite light i run 255's prior, and currently running the same tires again, after wearing out a set of 245-75 E's in mastercraft m/t flavor, there's only 1/2" difference overall roll out height between what i have now, and the 245's i had, but the comparison was night and day I actually like the 255 profiile more than the 245 profile and wish there was a larger variety of tires in 255 than there are because other than straight street tire, there's not a ton to choose from in any case, i wouldn't foresee any ramifications and other than churning higher rpm's at say, 65-70mph, (70 on 3.73's with 255's is about 2150-2200 RPM ish) just guessing the 4.10 would put it at about 2400 your highway will go down, but not drastically, your cruise function on the highway will work much better especially with long hills i would regar mine in a heartbeat just for the extra acceleration and crawl ratio, but.. with my combo, other than crawl ratio it performs about equally to one running 4.10s so I haven't bothered Go for it, can't fathom that you'd regret it |

I ran 4.10's with 245/70R16's and 245/65R17's before the lift. You will lose some highway mpg's. You will also lose some city mpg's if you can't stay off the skinny pedal. The acceleration is pretty cool though. |

Do you need to do any modifications when going with a 255/65/16 size tire? |

pound the pinch for 255/70 's and rubbed on fog light doors but neither were major |
