I have a question about the size of wheels, such as 17,18 or 20 inch. Is there a purpose behind this other than looks. I might sound stupid but the way i understand it myself if you have 20 inch rims and get 34's is it less tire or maybe its the same amount I'm not sure.

The only reason I'm asking is because i plan on getting a 2.5 inch and 3 inch rear block, and I'm not sure what size would be the best option for rim size and tire size.

Thanks.

 

No input on this?, Must of been a real stupid question lol

 

I don't think this is a stupid question. I am also interested in the same thing. I have the stock 20s and am putting on a 2.5 and 3 inch block over Christmas. I am considering selling the tires I have on now but I do not know which size to upgrade to.

 

Looks, everyone thinks bigger is better. The only reason I can see putting bigger diameter rims on trucks is to fit bigger rotors and pads behind them for better stopping performance.

There will be less sidewall on a 34" tires that is meant for a 20 inch rim vs a 34" tire on a 15" rim.

Usually the bigger the rim the more expensive the tire will be, but how common the tire size is also plays a role.

You can fit 35's I believe with your lift. I'm going to do the same lift this coming summer and keep the tire size at 33".

 

Most 4x4's that do some offroading use 17 or 18 inch diameter wheels. The tires have more sidewall protection from rock's, stump's and other obstacles then 20 inch tires that have a shorter sidewall. 20 inch tires with less sidewall have a little rougher ride on the highway then a 17 or 18 inch too. I ran 17 and 18's on my '04 and have the stock 20's on my '11. The 17 and 18 inch tires are usually less expensive then the 20's also.

 

Pretty much covered it. I'd say it's personal preference. I like the look of more tire sidewall around the rim so I run 17" rims with a 295/70 tire. Plus it's cheaper so win/win for me. Depends on the look you want, plus the above mentioned about the ride.

 

I have 20s on mine specifically because I liked the way they looked. After having my truck a year and a half I still love the way they look, however if I had to do it over again, I would go with the 18" rims as I off-road more than the average person and think they ride better.

 

I have a Lariat with 20's that I thought rode a bit rough with some road noise. This was confirmed when I took it in for service and they gave me a loaner that had 18's - much smoother and quieter ride. Personally, in hindsight I prefer the look of the 18"

 

Thanks for the input guys, and Thank you PawPaw you answered my question very well, Ive always liked 18 inch rims myself.

 

The Raptor comes with 17"s doesn't it? More sidewall for offroad. A lot of guys will swap their 18"s and 20"s for the 17"s because of it.
