Wheel sizes (1 Viewer)

[donjuanmiguel]

Hi all. Many of us have changed wheel sizes rather than stick with the 18s. Are there advantages/disadvantages to 16, 17, 18" wheels? My initial thought would be torque - smaller wheel size = more torque but this is just a guess.

Just for clarification, wheels are rims in my mind. Please feel free to correct me if my assumption is incorrect.

Pretty sure you can't fit 16s onto the 200, but no real advantages for 17 vs. 18. About the only thing that comes to mind is that there may be more options for a 17" tire than 18", and it may be cheaper for the 17s too. Other than that, you may be able to air down a 17" tire more than 18", but I'm not sure what that difference would be, and if it would make much of a difference.

When I hear wheels...I think rims too.

You can't go 16 as the brakes won't fit.

There is no torque advantage if you have 33" tires on a 16 vs. 33" on 17 or 33" on 18 -- the final circumference is all 33"

Dealing with the same size outer circumference tire, there is more rubber (higher aspect ratio) when dealing with smaller rims. So in theory, a 33" on 17's will cost more than a 33" on 18's, but I don't think the price is significant -- especially if you have to buy a 17" rim just to get it.

Chimyz is right -- there are more options for 17" rims, but that is slowly changing.

You can also air down the same circumference tire on a 17" more than on an 18" because there is a higher aspect ratio.

17's ride smoother than 18's, but not by much. Much less difference than say an 18's vs. 20's.

I'd say stick with the 18's unless you really have a preference towards 17's.

One day I'd like to do a Tundra brake swap and those kits are going to require 18's fyi.

Thanks for the info. No plans on changing to 17s just curious as to why some went from 18 to 17 on the 100 thread, a couple here too, I think. Availability could have been the primary reason.

I'm no spring chicken but the 100 and the 200 are my first 4WD vehicles so I have a bit of a learning curve. Needless to say, I've never moded either. More to point, I used to think when someone had 18" tires that meant the width of the tread. :whoops:

Great site, learning lots.

Different country/aera has got different rim dia.
To my understanding, Toyota's policy is, better road larger dia.
So, in country like Australia, Middle East, China have 17", USA 18", Europe and Japan 20".

17" better offroad.
20" better hiway. (LC is not good at hiway originally.)
