I have the standard 20" wheels and tires that come with all Platinums.

I was wondering if they make a 20" tire that isn't a low profile. The reason I'm asking is that I know the 18" ride a bit smoother than the 20". Although I really have no issues with the Platinum's ride (it is a slight bit more stiff than a Lariat I drove), if I can get a smoother ride, I'd consider changing tires if not completely going to 18" wheels.

Either way it's not a big deal. lol.

 

check out dubsesd's thread: 305's on a Platinum

 

To answer your question, they make every size imagineable for 20" wheels, from around 26" tall to 52" tall. The only limitation you'll have is what will physically fit under your truck.

 

Thanks for the link. I'm going to send him a PM and ask if those tires created a smoother ride then the stock tires.
