I've got a 2005 4x4 Diesel Ram Quad Cab. Currently running 265/70R17 Load E. Whats the largest tire I can fit on there? Also, how much to recalibrate for a larger tire size? Is there a 33 or 35 E range tire? Lastly, will this void my warranty if I go to a larger tire? This is my work truck so I don't want to lift it, but these little street a/t's are hell off-road. Thanks all.

If you don't offroad it you should be able to fit 35s. They might rub if you flex it out though. They shouldn't void the warranty for that. They can only void a warranty if they can proove that the aftermareket item caused the problem in question. So obviously there won't be any tire warranty from them, but that should be it. If you get a real a$$hole service writer they may try to blame the tires for trans or axle problems but it's unlikely.

As far as the speedo, I dunno how it is with the new style trucks but for my 2000 I just got a Superlift Truespeed for like $120.

my father has a 05 2500 HEMI with a 2" leveling kit with 35" BFG mudds and they come pretty close to rubbing if he flexes they rub bad but on the street everyday, no problem

I'd probably go with 33x12.5's then. They might look a tad small but will do a lot better offroad.

I had the 35/12.50/17 baja claws on my stock 05 2500 on factory wheels and I don't remember any rubbing...

You don't have to do that. I have taken mine back for warranty work a few times with the 35's on and the tech's have come up to me to compliment me on the truck's look. I had the 35's on with no lift and they rubbed the control arms at full lock. Since adding the Daystars, no rub at all. If you go offroad, then the 33 would probably work better for you. I run the 33 ProComp M/T's now for the winter and they ride pretty good and aren't too loud.

:withstupid: 35's rub on my buddies 05 ctd at full lock like my truck does. but if your gonna be offroading, 33's would be perfect, plenty of room to stuff em.

Mine only ever rubbed the control arms slightly at full lock...never got them to rub even when twisted up some.

From what I have read at TDR, there is a debate right now about whether you can have the speedo corrected on a 05+...something about the way they were entering it on the older models has changed with the 05 and they can only calibrate up so big now (not even close to a 35).
