Tire size under 3” lift?.... And does OVtune void warranty?

A couple of questions... first. What size tires are you guys fitting under a 3” lift with no rub?.... and. Does an OVtune void the warranty? I’m sure these questions have been asked numerous times, I’m just hoping someone can save me the trouble of searching old threads.

 

265/75/16 or 265/70/17. No it doesn’t void the warranty but good luck getting any drivetrain related issues fixed if they find out you’ve installed it.

 

The tune is completely undectable in the techstream software. The only way the dealership would know is if they were told the tune was installed.

 

So we’re saying the same thing?

 

Really??? I’ve got 265/75/16 Toyo M/T’s installed right currently with no lift and no rub. Was hoping to go a little bigger than that.

 

It’s good to know that the OVtune is undetectable.

 

Lift doesn’t solve rubbing, anything that will rub stock will rub lifted when you cycle the suspension. If you’re just cruising the mall then you may be able to go larger without rubbing, but most 33s are going to requiring cutting and possibly a CMC.

 

Good to know. I definitely am not driving a Mall Crawler.lol I’ll look into the CMC. Thanks for your help.

 

I’m actually running a 33” but it’s a tall skinny, 255/80/17 and I had just had to trim some plastic on the fender. I also have JBA UCAs which with 3 degrees of castor help push the wheel farther forward to avoid more rubbing.

 

You can go up to a skinny 33”. If you don’t mind a little bit of a rub, or if you do a cab mount chop, you can go with a fat 33”. I’ve heard that if you get a little happy with a sawzall, you can go up to a 35”. Not sure about the OVtune.

 

Do you have pics?

 

Best I can do right now. I need to take some better pictures of the truck. Gotta get the wife to break out her camera instead the shitty iPhone pics.

 

Good looking rig! I always thought these trucks look good in white. Thanks for the reference.

 

I’m running 1.8” of lift in the front with 255/75/17 (32”) no rubbing.



No OVtune doesn’t void your warranty. It’s friggin awesome though and you can actually enjoy your truck

 

Awesome!!! Thanks for the info.

 

You should be able to fit 275/75/16 or 255/85/16. Anything larger will need a cmc.

 

Really great information. I appreciate everyone’s help. My goal is a 285/75/16. Seems like I will have to chop the cab mount to get this done.

 

Truck looks great! I love the softopper. I can't wait to get my OV tune in the mail and loaded to the truck.

 

The newest revision of the tune, 1.05, does change your ECU ID. And yes, it does show up in techstream.

So you’ll need to flash back to a stock map prior to service. But once you’re back stock, it’s undetectable.

 

Tire fitment will depend heavily on proper wheel fitment. Put 'em on the wrong aftermarket wheel and you've got issues.
