Largest tire to run on 2.7l auto?

what is the largest tire a 2.7l auto trans handle? without any mods to diff

 

235x85 will roll on flat ground but don't even like hills

 

p265/70/16

 

well I was trying to go for a 265x70r17

 

you have 17 inch rims?

 

I wouldn't go with anything larger than a 285.

 

my biggest fear is hurting the transmission I am hoping someone else on here has tried different options and can let me know there experience

 

If you're afraid of damaging something, then don't change sizes?

265/75/16 or 265/70/17 and be done with it.

Modding has risk. If you're afraid to create a problem, then don't mod.

 

I ordered these wheels 17x9 I already have a 3 inch pro comp lift just want to see what tire size I should go with

 

bigger heavier tires hurt 4 cylinder performance,power,mpgs. if your going for looks than go bigger, if your looking for retaining performance with a better look >p265/70/16 would be best if you have 16 inch rims, there are plenty of threads about this in the Tires/ wheels or 4 cylinder forums just search the subject you can find lots of info there.

 

Weight (rotational) is a big issue too, stay away from E Load rated.

 

That should be fine. Won't hurt the trans but will hurt your ego going up hills on the freeway

 

This needs to be mandatory reading

 

Stop posting and read your thread.

Extra rolling resistance = extra forces applied to stock parts.

If you don't want to deal with increased maintenance/increased breakage of parts - don't mod.

Plenty of 3" lifts with 265/75/16 or 265/70/17s.. I wouldn't go any bigger than a 285 on a 4 cyl auto and stock gears, and my truck was slow enough with 265/75/16s, so much so that I'd personally never get 285s without re-gearing or without a manual transmission instead.

Your truck will be a dog, it will work harder to turn bigger tires, you will cause premature wear to parts therein.

 

I'm not afraid to mod just want to see if there are any other persons that have experienced with the 2.7l auto

 

Yeah lol, some chick on here threw a 6"lift and 35s on that and then complained about loss of power for about a hundred pages hahaha.

 

You're talking to one.

You're not listening to anything I say, except what you want to see.

Good luck.

 

okay thanks for the advice everyone! I can remember when I had a 89 pick with 22re and 33's not fast but had no problem running them

 

I'm running 265 70 r17 and there is a noticeable slowdown on hills. If you're planning on getting larger tires, you can't go much larger than this without re-gearing.

Also if you've go an auto, just drop it into 3 when you need to pick up some speed.
