Yeah ive seen some reviews where people say dont air the down. Popping a bead or damaging side wall and seen some say they so it all the time.. from my experience with off roading the side wall on the 20s suck. My 08 hemi I had before this one. I swapped the 20s for 17s and was a good switch. And yes the 17 inch tires are WAY cheaper. I know alot of jeeps and even the ram rebel have the 18in wheels. The 17s ive always had good luck withJust my 2 cents like you said airing down with shallow sidewalls is a gamble. Not to mention 20” tires to fit are expensive as heck. My thoughts on 17” is a good thought
Yeah there isnt much for a good tire in a 20 inch.On road feel is nice with 20" because theyll feel more firm; however the 17" wheel profile will be more forgiving off road and like Ben mentioned above the 17" options will be much cheaper and likely have more options for tires.
Almost every good/popular tire is available in a 20 inch version, BFG, Cooper, Goodyear, Toyo, etc.[/QUOTE
Yes you can get into any tire for a 20 wheel. But you have to be picky about size. 35. 11.5 20. Is hard to come by unless you go with nittos. I dont like the wide 12.5 tires. But if you get into weird tire sizes twentys arent the way togo
That is an aspect ratio issue, not a wheel size issue. Running a 20 inch wheel with a 45% aspect ratio is just as silly as running a 15 inch wheel with a 45% aspect ratio wrt to off-roading.Just my 2 cents like you said airing down with shallow sidewalls is a gamble.
Thats the size i am thinking about running on my ram if I keep the twentys. that is leveled up with 5100 bilstiens and a one inch spacer in the back. Brings the front up 2.8 inches ans the back up one. At the time the 285s were just fitting with stock coil overs35.4 or so
Do you have todo any suspension tweeks to get the bigger tire on GC? Saw a Cherokee the other day that looked pretty sweet.Interesting read. Our Grand Cherokee Overland has the 20" wheels, and surprisingly, tires for it are cheaper than for an 18" wheel. One of the tire shop guys said though, it all comes down to popularity/availability. The size I am looking it is larger than factory, but still a size that comes stock on a lot of pickup trucks (275/55R20) which explains the lower price.
Bet that sucker will scream down the road!No tweaks at all. The stock tire size is 265/50R20, but a lot of guys are swapping to 275/55R20 because they fit perfect. Anything wider or taller, nope. Not with the air suspension on the Overland. And having the Hemi plus tow package means HD brakes, which rules out fitting a 17" wheel. Would have loved to grab a set of used Wrangler Rubicon wheels and the stock 32" BFG mud terrains that come on them, but they won't clear the brake calipers!
