Minimum Wheel Diameter

[Puckwall]

Hi All,
Looking at a 2019 1500 Bighorn which I will want to put aftermarket wheels on.
Does anyone know what the minimum diameter needs to be?
I have Rebel 17" on my 2015 but its my understanding these will not fly on a 2019.
Any help would be appreciated.

Thanks,
Doug

Check caliper clearance and wheel offset

18 inch is the smallest on a 2019 5th Gen DT.

Do you have the 6 lug or the 5 lug classic.

If you have the 6 lug your old rebel wheels wouldn't fit anyways

If you have the 5 lug classic it is the same truck as your old rebel.

That said the 6 lug truck has a minimum of 18 and you have to buy very specific 18 inch or bigger.

The 5th Gen got bigger brakes and an extra lug nut

Agreed that the minimum is 18". I recently installed aftermarket 18's on my 2020 big horn. The clearance between the caliper and wheel is VERY tight. So tight, in fact, that the stick-on balancing weights (wheels and tires came already mounted and balanced from online retailer) were scraped off by the caliper. So 18's will work, but you have to be mindful of how/where the balancing weights are applied.
