anybody have an opinion? 18" wheels vs. 20"
Which, in your opinion, is a better size for tow vehicles and why?
Forum Discussion
PSI, E's, etc without their our yay robustness is out of context
In these larger dia wheels, in order to keep the rev's per mile (tire OD) requires lower as spect ratio tires
Meaning that high PSI creates a ballooning issue on the very flat tread area
So 80 PSI is out of context
Another issue with over sized (dia) wheels is that they have a higher centrifugal force issue....both getting it going and stopping....rubber weighs less than aluminum...and since a half ton....unstrung weight....ride quality degrades
If more than looks...the larger dia will have lower aspect ratio tires ov the smaller dia wheels
Lower aspect ratio has a higher POTENTIAL performance levels...but that is mostly boy racer stuff (track) on cars...TV's not so much boy racer....but... Those lower aspect ratio sidewalls does help or makes for better towing heavy in the twisties
IMHO...
