Let me start by saying that I don't know the answer to your question. Now that that's over, I had 20" rims on an 2008 F350, 18" rims on a 2013 Tundra and 17" rims on my current 2005 F150. For me no comparison in ride quality or looks, I'd take the 20" rims any day of the week over the rest. Loved my F350. The other trucks are good but F350 was like cruising in a limo compared to the rest. Tires wore quickly, esp. in back, but I think that had more to do with the weight of the vehicle and the fact that the rears had to be kept at 80psi for the TPMS. Personally, given the choice I'd go with the 20" over the rest.

 

Ah okay maybe that's what the difference is. I'm pretty sure my lariat was only 18" or 20"

 

I had 16" wheels with 35" tires on my 99 f350 for years. Ran great, handled well. Plenty of give for off roading.

Recently, I found a good deal on a set of 20" wheels. So I bought them and put them on with 37" tires. It rides different. I can't say better or worse. Just different. The bigger mud tires don't hold the road as well, but that's to be expected going from a mild all terrain to a mud tire.

It looks better, and is a bit taller. And the tires cost twice as much. that's about it.... I might go back to my old wheels when these tires wear out.

If I had the choice id go with 17" wheels.

 

If you're coasting to get replacements maybe you need to stop and get fuel first. That said they will coast a little further, given the same tire, 20" wheels have less rolling resistance but will cost more when you finally coast all the way to the tire store.

 

Stock Michelin tire specs when I purchased my 2012 F350:
.............................. tire wt... rev/mi... max load @ 80psi.... cost
265/70R17, 121R ..... 49.1 lb... 657.............2910 lb.............$266
275/70R18, 125R ..... 60.7 lb... 628............ 3640 lb............ $322
275/65R20, 126R ..... 61.1 lb... 606............ 3750 lb............ $405

When I purchased my truck the 20 in wheels could not be on 3.31.
The diameter of the 18 in tire is 33.2 in and for 20 in is 34.4.
I'm happy with the 20's that I have.

I hope this helps you, JG

 

them big rims look bad, get the smaller ones.

 

Do the 20's get stolen more often?

you can, but there is very little clearance. I'm surprised when Ford went to the bigger brakes in 2013 they didn't delete the 17" wheels.

 

It's a weight capacity issue. You can see it in the commercial order guide for C&C F350 SRWs with 17" wheels, they're required to have the Payload Downgrade package to de-rate GWVR to 9800#. SRW trucks won't have a RGAWR over 6390# with 17s because of the tire load index, 18 ans 20s will have a higher RGAWR.

 

I agree to a point. 20's on 38" or larger tires looks nice but what looks stupid is when you have 3" of tire and a rim that is way too big

 

but then again, it all comes down to personal preference, even tho you might not like them, other people do, and if all they do is road driving then for them it might be a good choice for them. That is the beauty of living in this country, we are free to make our own choices and have our own opinions.
I myself don't have an opinion either way, 25 - 30 years ago I would probably had my truck sky-high and the biggest wheel/tires I could run, but now with getting older and harder to get into a lifted truck I don't want something I need a 10' ladder to get into, same with wheels/tires, I am running stock wheels/tires right now but may upgrade to a nicer wheel with the same size tires. Dodge has been running 20" wheels for several years now and honestly if you were just looking at the truck you wouldn't know it.

 

You get better fuel mileage with 20 inch wheels.......because your wallet is so much lighter.

 

Not the same bolt pattern as Hondas and Toyotas.

 

I would think that a set of rims and tires would outweigh the little
Ricers anyway

But know how thieves are. It it's not nailed down...
