305/65/20. 305x.65= 198.25. 198.25/25=7.93. 7.93x2=15.86. 15.86+20=35.86. It looks complicated but it's easy the first number is the width of the tire and the second number what % of the width is to the side wall. Once you get your side wall you times it by two for both sides of the tire then add in your wheel size and Walah.
Well I have been on here researching what tire size I would go with on my 2012 2500 HD LTZ with factory 20's. Finally decided to go with the 305/55R20 even though some have issues with rubbing. Had mine installed today with no rubbing at all. The Ready Lift Keys put the front up enough to clear. Tires are Dick Cepek Radial FC II's.
I went with the 305 50 20's because they were close to the factory overall diameter by 0.30". The factory 17" tires were 31.7" tall, these are 32.0" tall, that way if I got a flat I could still use my spare safely. 2011 Chevrolet Silverado 2500 HD LTZ Crewcab Duramax/Allison.

THe new LMLs can take a larger tire than any previous gen Dmax in stock form. As for the OP qusetion the stock 18" rims are 8" wide. Every manufacturer will spec a recommended a range of rim widths for their tire. Most 305's that I have looked at recommend a 8.5" minimum rim width so 8" is pushing it a bit.
Looking for pics of tires and/or leveling kits on the 2020’s. Don’t care if it is a GMC or Chevy. Just want to see what everyone is doing. 2020 GMC 2500 HD Denali, 35x12.50R20 Nitto Ridge Grapplers & Mayhem Warriors-Traded. Now: 2022 GMC Sierra 1500 AT4, loaded, 295/70-18 Ridge Grapplers, & Rough Country leveling kit.
Also cant decide on tire size that will give best appearance without rubbing and trimming. 285/60/20, 295/60/20, or 305/55/20. Following... I was planning on running the stock 18" Dennali wheels and had decided on a set of 305/65/18 Falken Wild Peak AT's.

I had 305/55/20 on my LMM and the front isnt lowered or anything and it would rub so bad that the the fender got bent, but the again i have a -12 offset and 4.5 backspacing so that had alot to do with it. Now i am running a 285/50/20 and it doesnt rub
305/55/20 PSI advice. Im putting the rig in the shop next week to have my tire sensors reset so my "check tire pressure" light goes off. Ive been runnin all four corners at about 55psi to soften up the ride...I haul a 4 wheeler and a 19' flat bottom boat so 70 PSI isnt necessary. Before I pay the dealer to reset my PSI range Id like to hear any ...

Those tires have a max pressure rating of 65psi which makes them ride a lot smoother than the tires with the max pressure rating of 80psi, it is really noticeable how they smooth out the bumps going down the road.
