My 2007 Fleetwood Excursion came with the G670s in size 275/70R22.5 mounted. Recently, I needed replacement tire "right now" and, even though I was within 70 miles of San Francisco, there was not one available, and I tried several sources.
I finally allowed myself to be convinced to install a G169 instead. It is installed on the inside rear passenger side position.
The only differences I can determine from the online specs on the Goodyear website is that the tread on the G169 is 3.5 32nds deeper (18 vs 14.5) and the OD is .1" (37.6" vs 37.7") greater. All other specs, including max load (6940@125psi), width (10.4"), and load range (H) are identical.
Oh, yes, the G169 is about $150 less than the G670.
My question is, did I do a "bad" thing by not waiting for a G670 to be shipped in?
When the time comes to replace the other G670s, are they worth the extra bucks?
