285s and auto trans

I was wanting to hear if anybody out there had trans trouble after going to bigger tires.

 

I wasn't sure have had problems whit autos before ,and the tires on the first gens are to small for my liking.

 

The newer trucks have better meat under them from the the factory.

 

You should'nt have any issues with a bigger tire size. i have people come through my shop all the time with bigger tires and no issues. It would help if you have a factory or installed a aftermarket trans cooler. The tires do reduce power and torque so the engine and tranny have to work harder. If you tow often you should keep how big of a tire into consideration and make sure you have a trans cooler. Other then that, you should be just fine.

 

What size of tire do want to run?

 

285 70 17

 

I think your fine. I have read when you bump up to 35's there can be some trans searching.
It's just a fact that larger heavier tires will cause transmission search and reduced mpg's.
Something I would not be happy with. Some guys do the regear thing to run 35" to 37"larger
tires a lot more $$$ than I am interested in spending for the look.

FWIW..
