Looking for info on a 37” tire or something close to it on a 17-19 with level kit or a 20-22 with 3 1/2” spacer it 2 1/2” coil lift. 35s will be too small since stock on my platinum are 34.1”. I did a 2 1/2” ready lift coil lift which raised my 2021 3 1/2” over stock.

 

Nobody has 37’s on stock wheels?

 

i have a 17 cclb with a leveling kit and 37's on stock wheels

 

I read about 1 person with 37'son stock wheels. he reported accelerated center tire wear . this is caused by the bowing of the tire surface due to the tire he used being put on a standard rim. the rim was too narrow.

 

I just don’t want to mess around with swapping wheels anymore. Was thinking a 37x11.5 would fit with no rubbing. 35s look like donuts

 

This is what it will look like. You'll have rubbing on the sway bar and radius arms.

 

that video helps a lot. I think I’m higher because I the ready lift spring kit says it’s 2 1-2” but it actually lifts the truck 3 1/2” on 2020 and newer they are incorrect in the advertising. Also I wonder if the 11.5” wide tire will help being 1/2” narrower on the inside?

 

In the case of radius arm and sway bar rub I wouldn't expect higher lift to make much difference. A narrower tire yes, but is 1/2" narrower enough to completely eliminate rub, maybe....or at least minimize it to a minor occurrence at full lock. You might not even notice it in the cab.

I saw a guy (youtube) who put 37x12.5's on stock wheels with a 2.5" spacer lift, he claimed to have only slight rub sometimes at full lock. They were an all terrain type tire. It's possible his tire choice ran a little smaller than some others in that size.

 

wouldnt tire height have zero affect on tire wear? It’s the width that would cause that. I have 35 12.50’s on the stock rim with no abnormal tire wear so stepping up to a 37 12.50 should be the same I would think

 

If you want zero rub and want to keep your factory rim with a 37x12.50, you need a 1'' spacer
