Any thoughts on the tallest/skinniest tire for '06 Envoy Denali with 18" wheels? oem 245/60/18
Appears that spacer may be required for 30s on the front only, rear has plenty of room.
Would be nice to have taller tire to effectively lower the 3.73 gearing. Don't do heavy towing anymore, & the 5.3 jerks everyone's neck when light turns green.
Here's a handy chart for 16" & 17": http://forums.offroadtb.com/viewtopic.php?f=15&t=2290
