Now these are for towing with small 5th wheel and as a driving around town vehicle.
We live in Ontario so we get our fair share of snow and ice and want a tire that can also handle this kind of weather.
Pondering if I should just get rims and go down to 17 inch tires?
these tires already are expensive so lets just say money isn't in the equation for rim and 17's vs 20's
going to 65 instead of 60 will change my speedo and gear ratio
would going down to 17 with new rims do that to?
if you drop to a 17" rim then you need to keep it at a 33" tire to keep the speedo correct or get a superchips programmer so you can adjust it to make the speedo correct.
275/60/20 is a 33" tire.
less rim and more tire = the diffrence will be a mushy ride
more rim and less tire = harder ride since the side wall does not flex.
my truck came stock with the 20" wranglers - I added a 6" lift and went to 305/70/18 (35" tire) and noticed the diffrence right away.
also if you go with aftermarket rims - watch the back space cause it will cause your turning radius to be greatly reduced - wider turns
I would add a rear sway bar - if will get rid of the teater totter feeling when you hit corners no matter what tire you go with.
