2019 GMC Sierra Limited (so the older body style 2016-2019) with 22x9 (is that right? they're 22s for sure) stock 7-spoke LPO wheels. That may not be what they're actually called. That's just what the dealer site said they were when I bought the truck.


4" BDS lift customized with rear lift springs instead of blocks (because I tow a boat and lawn trailer a lot), the Fox shocks because why tf not, and no recoil system because it's only a 4" lift.


I asked BDS themselves, and they gave me the generic "specified tire size" from their site. With this lift, BDS says I can run a 33x12.50 with 17 or 18x9 and 5" backspacing...or a 35x12.50 with a 20x9 and 5.75" backspacing. Trimming may be required of course.


Does anyone know the actual largest tire size I can run? Was gonna go with a Mud Grappler, but their smallest is a 37" tire with 22s. Don't need your thoughts on the tire choice. It's what I want.


I've had Toyo Open Country M/Ts on a previous truck. They make a 33 and 35x12.50 for 22s. Or even a LT295/55R22. Which of those would fit best?


What could I run if I traded out these 22s for some aftermarket something in a 20x9? Grapps make a 33 or a 35 that should fit then.


Pic for attention, not the actual truck. Thanks in advance, everyone.

33”s will fit fine. 35” are cutting it close with a 4”, and will rub. Have to trim up some plastics, and Norcal mod to go full lock in reverse. Basically exactly what BDS said.

A 33” tire is 33 inches tall. First number is overall heigh x width. So 33x12.50r17 and 33x12.50r26 are both 33” tall and 12.50 wide, it’ll fit. A 35” tire will not.
